March 29, 2024
Audubon has joined partner conservation organizations to propose “Cooperative Conservation” as an alternative for the federal Bureau of Reclamation (Reclamation) to study as they consider how to manage the Colorado River after 2026, when current management rules expire. Reclamation has initiated a process expected to assess multiple alternatives before they establish new operational rules.
In recent weeks the Upper Basin (Colorado, New Mexico, Utah and Wyoming) and Lower Basin (Arizona, California and Nevada) have each submitted proposals of their own. They appear to be in broad agreement that Colorado River water uses need to be reduced, not only because the Colorado River’s water is over-allocated, but also because climate change is shrinking the river. But alignment between the Upper Basin and Lower Basin ends there, with significant dispute over whose water uses should be reduced.
Cooperative Conservation has a different focus. It prioritizes stabilizing the Colorado River water supply, provides opportunities to make management more equitable, and creates mechanisms to improve environmental outcomes [ed. emphasis mine]:
Water supply reliability would be improved by consideration of recent trends as well as assessing the health of the entire system, departing from the current operations that have not kept up with changing conditions such that in 2022 federal managers were worried about the continued ability release water through the dams.
Ecosystem health would be addressed with stewardship and mitigation provisions. Today’s operations are based on a policy framework that has not prioritized Colorado River habitats, leaving many used by birds such as Yuma Ridgeway’s Rails and Yellow-billed cuckoos degraded and vulnerable.
Colorado River Delta habitats and flows have been restored in recent United – States Mexico agreements, and the opportunity for future binational agreements to extend and expand commitments to these resources would be preserved. Most of Colorado’s Delta was desiccated as the river was developed through the 20th century, and these agreements have developed a path towards restoring some of what was lost.
A Conservation Reserve program to incentivize water conservation, that improves on the current system of “Intentionally Created Surplus” by adding to the stability of water supplies, offering an opportunity for state and federal governments to forge an agreement with Colorado River Basin Tribes looking to realize greater benefits from their water rights, and create ecological benefits through flexible management that puts water where it is needed in the Colorado River.
These innovations could help the diversity of birds and wildlife and more than 35 million people who depend on the Colorado River. But Reclamation will not be able to move forward with them if the states cannot answer important questions about who should reduce water uses to bring demands into balance with supplies. Without consensus, Colorado River management could be headed to the courts, and opportunities for improved management will be lost. We remain optimistic that over the coming months the states will negotiate a solution, and urge them to recognize that reaching agreement on how to share water shortages is essential.
In the meantime, Audubon will be promoting Cooperative Conservation and all that it offers. Reclamation is expected to publish their analysis of Colorado River management alternatives by the end of 2024.

A federal rule to put conservation on par with extractive industries will not be subject to the Congressional Review Act that could allow it to be easily overturned, a U.S. representative from New Mexico said Monday.
The Bureau of Land Management has drawn criticism from Wyoming’s governor, its D.C. delegation, industrial leaders and agricultural interests after finalizing the Public Lands Rule last week. But a coalition of conservationists defended the BLM in a press call Monday organized by the Conservation Lands Foundation and The Wilderness Society.
The rule will allow the BLM to consider “mitigation restoration leasing” equally with other uses like grazing, mining and oil and gas development.
The rule identifies conservation tools to keep natural landscapes intact and restore them where degraded, a move advocates say marks a shift from what the BLM has considered or ignored when setting frameworks for use of its 18.4 million acres in Wyoming.
Although Republican U.S. Sen. John Barrasso, a staunch advocate for the energy industry, has said he would use the Congressional Review Act to block the rule, U.S. Rep. Melanie Stansbury, a Democrat from New Mexico, said that’s not going to happen.
The review act, successfully employed by former U.S. Rep. Liz Cheney to block another BLM planning effort in 2017, is subject to time limits and deadlines that make its successful use improbable in this instance, Stansbury said. “This rule being finalized now should protect it from a rollback by Congress,” she said. “It should be fine in terms of making it ineligible for Congressional Review Act repeal.”
Wyoming native Jordan Schreiber, a lobbyist for The Wilderness Society, said she was “very confident” about defending the rule. “I’m not losing sleep over it,” she said of congressional discomfort.
A durable measure
To thwart the rule, Barrasso last year introduced a bill that targets the BLM initiative. Nine senators, including U.S. Sen. Cynthia Lummis, another Republican, joined as sponsors. The bill has not advanced.
Industrial users also have challenged the plan, as has Gov. Mark Gordon, who questioned the constitutionality of the BLM action. The Petroleum Association of Wyoming called it “a new, extra-legal, executive branch authority.” That suggests lawsuits will be filed.
BLM supporters said the rule will survive such legal challenges. “We are confident that the rule will prove durable over time and we intend to strongly defend the rule … in the courts,” said Michael Carroll, BLM campaign director with The Wilderness Society.

New Mexico’s Stansbury also dismissed misinformation. “This is not a land grab,” she said, blaming Republicans for inaccurate spin.
“This is not an attempt by the federal government to take away activities on public lands,” including utilizing resources “that we use in everyday life,” Stansbury said. “This is really about modernizing the way that we do land management. It’s about putting conservation and cultural uses on par with extractive uses.”
Congress stated that the BLM “should not emphasize the greatest short-term economic element,” when outlining how to manage its 30% of Wyoming’s land and 245 million acres nationwide, said Chris Winter, a professor at the University of Colorado Law School. The U.S. 10th Circuit Court of Appeals has said that “conservation to protect environmental balance” is one of the uses the BLM must weigh along with oil and gas development, grazing and so on, Winter said.
Lander resident Bailey Brennan, an attorney and farmer, said her 3-year-old daughter has been with her on three pronghorn hunts on public lands, all possible because of intact migration corridors. With the rule, restoration leases will allow the National Wildlife Federation she works for to help fight cheatgrass and restore riparian areas along those routes.
That type of work will ensure daughter Frances could have the same pronghorn hunting experience “when she is a grown-up with her children,” Brennan said.

Conservationists point to graywater uses as a way to cut down on water consumption in the West
A bill that would allow graywater systems to be included in new homes throughout Colorado received rare unanimous approval from the Colorado House on Friday…The bipartisan House Bill 2024-1362 (Measures to Incentivize Graywater Use) is sponsored by Rep. Meghan Lukens, D-Steamboat Springs, and Rep. Marc Catlin, R-Montrose, Sen. Dylan Roberts, D-Frisco, and Sen. Cleave Simpson, R-Alamosa…Currently, local governments are permitted to opt into graywater programs. Under the bill, the whole state would be automatically allowed to include graywater systems in new constructions, but local governments could choose to opt their community out…
Since the state gave initial approval for local governments to opt into graywater programs in 2013, only six jurisdictions have chosen to do so including Pitkin County, Grand Junction, Denver, Castle Rock, Fort Collins, Broomfield and Golden. If approved by the Senate and signed by the governor, the bill would go into effect at the start of 2026.
Graywater is mentioned in the Colorado Water Plan as a possible tool for the state to meet current and future water needs. It notes there are challenges with the technology, including the effort of retrofitting existing buildings with the systems. It also includes a “general lack of interest on the part of local governments to enact local graywater ordinances,” a “lack of interest from developers” and “concerns that property owners could be resistant to operating and maintaining a graywater system within their residences” as challenges.

March 13, 2024
This story is part of ongoing coverage of the Colorado River, produced by KUNC in northern Colorado, and supported by the Walton Family Foundation.
The Gila River Indian Community says it does not support a three-state proposal for managing the Colorado River’s shrinking supply in the future. The community, which is located in Arizona, is instead working with the federal government to develop its own proposal for water sharing.
The tribe is among the most prominent of the 30 federally-recognized tribes that use the Colorado River. In recent years, it has signed high-profile deals with the federal government to receive big payments in exchange for water conservation. Those deals were celebrated by Arizona’s top water officials. But now, it is diverging from states in the river’s Lower Basin — Arizona, California and Nevada.
Stephen Roe Lewis, The Gila River Indian Community’s Governor, announced his tribe’s disapproval of the Lower Basin proposal at a water conference in Tucson, Ariz., while speaking to a room of policy experts and water scientists.
“This is not the time to be standing on the sidelines,” Lewis said. “We all have a responsibility to do what we can. And that’s why The Community can’t support the current Lower Colorado River approach as it stands now.”
The announcement adds a new wrinkle to an already-complicated process. Last week, the seven states that use the Colorado River unveiled competing plans for managing its water. The Lower Basin states revealed one, and the Upper Basin states – Colorado, Utah, Wyoming and New Mexico – revealed another. The opposing plans represent stark ideological differences between the two groups of states, marking the latest disagreement between rival camps that have argued over water management for decades.
Lewis, who has positioned his tribe as an ally to the federal government in helping save water, outlined a few major sticking points that led Gila River to work on its own proposal.

One issue, Lewis said, is that the Lower Basin’s proposal creates an “unfair burden” on the state of Arizona. Under the proposed plan, all seven states would have to cut back on demand for water if levels in the nation’s largest reservoirs — Lake Mead and Lake Powell — drop below a predetermined trigger in the future. Arizona would take the largest of those cutbacks.
Another, he said, is that the Lower Basin’s plan does not explain how it would mitigate the impact of those potential new water cutbacks. Lewis said he would like to see plans to identify new sources of water away from the Colorado River that could replace water lost to cutbacks, or financial compensation.
States are under pressure to agree on plans to manage the river before 2026, when the current guidelines for sharing its water expire. Both of last week’s plans came just ahead of a deadline from the Bureau of Reclamation, the federal agency which manages the West’s dams and reservoirs. The deadline was an effort to get the ball rolling on new river rules with enough time to implement them before a potential change in administration after the upcoming November election.
Reclamation officials said they expect to work with states over the spring and summer and reach a draft for post-2026 river management rules by the end of 2024.
Now, Lewis and his staff are working with Reclamation on what could potentially be a third competing proposal. He said he hopes a proposal will be released in “weeks,” rather than months.
“It’s potentially not just the Gila River, because this will affect other tribes as well,” Lewis said. “I wouldn’t be surprised if other tribes started to register their concerns as well.”
As states and the federal government draw closer to a new set of river management rules, some tribes have repeatedly expressed frustration about being excluded from negotiations. Tribal communities often lack reliable access to clean water due to aging infrastructure and a history of underinvestment, and many are calling for greater inclusion going forward.
Lewis said that was not the issue in this case, and that the Gila River Indian Community was included in talks.
“We were at the table,” Lewis said. “It’s just the proposal, the finished product as it is right now, doesn’t reflect our concerns.” [ed. emphasis mine]

On behalf of our respective organizations, the undersigned conservation groups (Conservation Groups or Groups) submit the Cooperative Conservation Alternative (Cooperative Conservation) to contribute to the ongoing dialogue shaping the future of the Colorado River through the post-2026 NEPA process for developing Colorado River Guidelines and Strategies.
The Groups request the Bureau of Reclamation include Cooperative Conservation in its analysis of post-2026 Colorado River Guideline Operations and Strategies as a forward-looking, comprehensive approach for addressing the pressing and evolving challenges facing the Colorado River Basin, its ecosystems, and the diverse community of sovereigns and stakeholders who rely upon its resources.
Cooperative Conservation is designed to inform and enhance one or more alternatives for consideration in developing the post-2026 Colorado River Operations and Strategies Environmental Impact Statement (EIS). It emerges from a synthesis of lessons learned, a deep understanding of the Basin’s environmental dynamics, and a commitment to collaborative, equitable water management, and endeavors to introduce innovative strategies that balance the needs of human and natural systems under the shadow of climate change and increasing water scarcity. [ed. emphasis mine]
The urgency to redefine the framework for Colorado River operations cannot be overstated. The Bureau of Reclamation’s (Reclamation) notice of intent to prepare an EIS for the post-2026 Colorado River marks a critical step toward addressing the Basin’s future needs (“Notice of Intent To Prepare an Environmental Impact Statement for Post-2026 Colorado River Operational Guidelines and Strategies for Lake Powell and Lake Mead,” 88 Fed. Reg. 12345 (June 16, 2023)). The existing guidelines, while pioneering at the time of their inception, are now recognized as insufficient to navigate the complexities of prolonged drought, escalating impacts of climate change, and pressing needs of a diverse array of sovereigns and stakeholders. Cooperative Conservation is rooted in the recognition that the Colorado River Basin has entered an era of uncertainty, where traditional management approaches must be reevaluated in light of scientific advancements, changing hydrological patterns, and the imperative of sustainability.
“New plot using the nClimGrid data, which is a better source than PRISM for long-term trends. Of course, the combined reservoir contents increase from last year, but the increase is less than 2011 and looks puny compared to the ‘hole’ in the reservoirs. The blue Loess lines subtly change. Last year those lines ended pointing downwards. This year they end flat-ish. 2023 temps were still above the 20th century average, although close. Another interesting aspect is that the 20C Mean and 21C Mean lines on the individual plots really don’t change much. Finally, the 2023 Natural Flows are almost exactly equal to 2019. (17.678 maf vs 17.672 maf). For all the hoopla about how this was record-setting year, the fact is that this year was significantly less than 2011 (20.159 maf) and no different than 2019” — Brad Udall
The significance of this Alternative lies not only in its aim to expand consideration of ways to address the immediate challenges, but also in its vision for a resilient and adaptive future that honors the interdependence of all who share this vital river. By embracing a holistic perspective that integrates scientific insight, stakeholder inclusivity, and environmental stewardship, our alternative is a framework for optimizing every drop of the Colorado River to better ensure it can remain a life-sustaining resource for future generations.
As the Conservation Groups submit this Alternative, we are mindful of the collective effort required to steward the Colorado River through the challenges ahead. We look forward to engaging in a constructive dialogue with Reclamation, the Basin States and Tribes, and all interested stakeholders involved in this essential process, united by our shared commitment to the River that sustains us all.

This is an installment of the Landline, a monthly newsletter from High Country News about land, water, wildlife, climate and conservation in the Western United States. Sign up to get it in your inbox.
In 2018, Brian Richter, a hydrologist and water sustainability expert, hooked a camper trailer to the car, and he and his wife embarked on a road trip up the spine of the Rocky Mountains. It was one of the driest years in a two-decade-long regional megadrought, and the entire Southwest was parched. Wildfires raged from British Columbia to Colorado, while reservoir levels continued to plummet.
As Richter traveled through the West’s uplands, he saw all the expected signs of drought: Tinder-dry forests, diminished streamflows, stressed vegetation and a ubiquitous pall of smoke that irritated eyes and lungs and blotted out the view. But he also noticed something that struck him: Nearly every valley bottom was still relatively verdant, even lush, despite the desiccating conditions.
The reason, of course, was irrigation. A major part of the settler-colonial project has been a determined effort to harness the West’s rivers and streams to raise crops and support a growing population. This has not only succeeded, it has altered much of the landscape, establishing a stark dividing line between irrigated and non-irrigated lands. “It’s part of our aesthetic as Westerners,” Richter said.
While golf courses, turf and booming desert cities gulp up a lot of water, the lion’s share of the West’s water still goes to growing crops and turning rural valleys green. Richter got to wondering: Precisely where was all that water going, and how were the different uses affecting various ecosystems? So he set out with a team of researchers to deconstruct the drivers of Western water consumption.

They found that 86% of the water consumed in the Western U.S. is used to irrigate crops. Everything else — from energy development to swimming pools to Las Vegas’ elaborate casino fountains — gets by on the remaining 14%. In the Colorado River Basin itself, things are marginally more balanced, with agriculture consuming about 79% of the water. Most of that, however, is used to grow food for cattle — alfalfa, hay and grass.
“We were quite surprised to see how large a proportion was going to cattle crops,” Richter told me in a Zoom interview earlier this month. The findings were published in Nature Sustainability in 2020. The article’s title — “Water Scarcity and Fish Imperilment Driven by Beef Production” — grabbed media attention and sparked many a news story that blamed the Colorado River’s demise on our appetite for cheeseburgers and steaks and the hay necessary to create them.
This spring, Richter and his team published an update of sorts, this time focusing entirely on the Colorado River. It’s the first-ever complete accounting of the system, encompassing water use from the Gila River, a tributary in New Mexico and Arizona, and all the consumptive uses[1] of the Colorado’s water, including reservoir evaporation and riparian and wetland evapotranspiration, as well as out-of-basin exports to places like Denver and the Rio Grande watershed, and water use in Mexico.
Sadly, this more complete tabulation exonerates neither bovines or beefeaters. Still, though the percentages going to cows and alfalfa farmers didn’t change significantly, it did provide more detail on those uses. Findings included:
Irrigated agriculture is by far the dominant consumer of Colorado River water, accounting for 52% of overall consumption (which includes reservoir evaporation and riparian and wetland evapotranspiration) and 74% of direct human consumption.
Cattle-feed crops (alfalfa and other hay) consume more Colorado River water than any other crop category, accounting for 32% of all water from the basin; 46% of direct water consumption; and 62% of all agricultural water consumed.
Cattle-feed crops consume 90% of all the agricultural irrigation water in the Upper Basin — three times more than is consumed by municipal, commercial and industrial uses combined.
19% of the water supports the natural environment through riparian and wetland vegetation evapotranspiration along river courses.
This accounting can help guide water managers in making the estimated 2-to-4 million acre-feet of cuts from the total annual consumption necessary to stabilize reservoir levels. Even larger reductions will be required to bring water consumption into balance with availability, as climate change-exacerbated drought and heating continues to further diminish the Colorado River. And yet, so far, the Upper Basin and Lower Basin states aren’t even close to agreeing on how those cuts should be made, or who should bear the burden.
Alfalfa and other cattle-feed crops consume 90% of all the agricultural irrigation water in the Colorado River’s Upper Basin.
The Lower Basin states — California, Nevada and Arizona — use far more water than the Upper Basin states. But when drought years shrink the Colorado River, the Upper Basin is forced to cut consumption under the 1922 Colorado River Compact. Therefore, the Upper Basin’s representatives argue, the Lower Basin should bear the burden of future cuts. The Lower Basin is willing to accept 1.5 million acre-feet of cuts, but beyond that, it wants its upstream counterparts to share the load. That amounts to an 814-billion-gallon gap between the competing proposals.
There’s a tendency to believe that rapidly growing desert cities — and ostentatiously profligate water-users, such as golf courses and lawns and swimming pools — ought to bear the burden of the cuts. But even if you cut off all the pumps in Lake Mead that serve Las Vegas, it wouldn’t make much of a difference. Southern Nevada’s consumptive Colorado River water use is about one-tenth of the Imperial Irrigation District’s in Southern California, where monumental amounts of water go to growing alfalfa and other food crops. And even as its population soars, Las Vegas is using less and less water, a phenomenon Richter terms “decoupling.”
“The only dial we have to work with is irrigated farming,” Richter said. His accounting would seem to offer an easy out: Just stop growing alfalfa and fallow the fields, or shift to less water-intensive crops. But it’s not quite that easy.

Alfalfa is a paradoxical crop: It’s thirstier than other crops, yet also relatively drought-tolerant. It doesn’t need to be replanted every year, meaning that less tilling of the soil is required. It can be harvested by machine, so it doesn’t require a lot of increasingly hard-to-find human labor. And it’s always in demand: Though beef cattle numbers are on the decline in some Western states, the dairy industry is burgeoning — and alfalfa is important for dairy operations.
Rather than reducing alfalfa acreage or production, some Colorado River Basin farmers, especially in Utah and Arizona, have begun growing more since the megadrought began. The federal government has forked out millions of dollars to pay farmers to stop growing alfalfa, or at least to stop irrigating their fields. But that can only achieve a fraction of the needed cuts, and it is hardly sustainable over the long term. And, by reducing overall supply, it drives up prices for hay, incentivizing other farmers to switch to alfalfa rather than away from it.
Besides, shutting down farmers’ ditches and spigots would imperil those emerald ribbons of green that curl through the West’s dry rocky valleys. Agricultural irrigation greens up more than crops: The farm fields’ runoff and leaky canals also nurture willows and wetlands as well as the wildlife that depends on them.
It’s quite the quandary, and it’s hard to see a clear path to sustainability. What is clear is that massive changes are long overdue, and those changes will alter the Western landscape, perhaps returning it to something that resembles the days before industrial-scale irrigation began.
“It’s really intriguing to me to think about how the Western landscape is going to have to change,” Richter said. “What we’re talking about is not unlike the fossil fuel industry, especially coal, as it goes into decline. The ramifications for regional and local economies and the culture and social fabric of communities are even going to be greater, especially for agricultural communities.
“It’s going to be an interesting decade ahead,” he added. “And I sure wouldn’t want to be one of those negotiators on the Colorado River.”

[1] Consumptive use is the amount of water withdrawn from the system and not returned to it. The Southern Nevada Water Authority, for example, withdraws about 450,000 acre-feet from Lake Mead annually — far more than the 300,000 acre-feet it’s entitled to under the Colorado River Compact. But it also returns more than 200,000 acre-feet in the form of treated effluent, giving it a consumptive use of 223,670 acre-feet in 2022.

Lawns are nice. But they use a lot of water, can be expensive and often don’t make sense for many of us here in the high desert. The Beyond Lawn program wants to help. The program is a joint effort between the Eagle County Soil Conservation District, the local office of the Colorado State University Cooperative Extension Service and the Eagle River Coalition. The idea is to help residents responsibly replace their lawns with attractive, water-wise landscaping. Cooperative Extension will provide volunteers from the Master Gardener program to help put the right plants into the right soils. The Master Gardeners are also helping create demonstration gardens in Edwards, Eagle and Gypsum this spring.
The program will also offer turf conversion rebates to residents. Denyse Schrenker of the Cooperative Extension noted that the Eagle River Water & Sanitation District has had its own turf conversion program for a while now. The Beyond Lawn program will offer similar services to residents who aren’t customers of the water and sanitation district. To participate, residents can sign up for an evaluation through the Beyond Lawn website. Evaluations cost $100 and provide expert reports specific to a resident’s yard, including soil types and lists of plants that would work to replace turf grass in those yards…
Rose Sandell is the Eagle River Coalition’s Education and Outreach Coordinator. She said part of last year’s efforts included determining how to approach residents with what can be a big request.
“We’re trying to break down the scariness of it all … down to manageable pieces,” Sandell said. She said that a piece of a yard where it’s hard to keep grass growing could be a good place to start turf replacement.

On March 4, 2024, the Upper Division States of Colorado, New Mexico, Utah and Wyoming acting through the Upper Colorado River Commission (UCRC) directed implementation of the 2024 System Conservation Pilot Program (SCPP). The 2024 program focuses on projects that support: innovations in water conservation, local drought resiliency and better understanding related to a potential Demand Management program. The 2024 SCPP was developed based on input from water users, water management organizations, and previous SCPP participants. The Commission recommended 115 projects move forward for implementation. These projects will conserve approximately 70,000 acre-feet of Colorado River water across the four Upper Division States, and include participation from Tribal, agricultural, industrial and municipal water users. The SCPP program is funded by the Inflation Reduction Act and is a unique collaboration between the Bureau of Reclamation, the four Upper Division States acting through the UCRC, Upper Basin Tribes, water users, and other stakeholders. The conservation projects are expected to be implemented beginning in April 2024.
Anne Castle – “The SCPP is a tremendous example of federal – state – tribe – water user collaboration resulting in partnerships and water conservation that improve the Colorado River system. This program represents one of the tools in the Upper Basin toolbox that can be used to contribute to a more sustainable river system. Many thanks to the Reclamation, UCRC, Tribes, water users, and State staff for the ongoing efforts that allow us to take this important step together.”
Rebecca Mitchell – “System conservation is challenging, but we have learned a lot and have used our experiences to build a better program this year. Water users in Colorado are using the SCPP to explore and develop innovative ways to prepare for a drier future. I am hopeful that the lessons learned this year will provide new tools that will support Colorado water users in the future.”
Estevan Lopez – “The water conservation actions being implemented in the Upper Division States are significant, especially in light of the uncertainty our water users face every year due to hydrologic shortages. The partnerships and tools being developed through the SCPP will help us manage Colorado River operations as climate change impacts our future water supplies. Some SCPP projects will provide a unique opportunity to explore the feasibility of a potential Demand Manage program. ”
Gene Shawcroft – “Utah water users have stepped up once again in 2024 to support the Colorado River system through robust participation in the System Conservation Pilot Program (SCPP). Through this year’s SCPP projects, the Colorado River Authority of Utah looks forward to learning more about demand management feasibility and innovative water conservation strategies in our state. I am grateful to the UCRC staff and consultants, Authority staff and the Utah Division of Water Rights staff for standing-up this important effort.”
Brandon Gebhart –“Many Wyoming water users are developing new approaches and tools to sustain their operations in the face of a future with additional water supply uncertainty. They recognize SCPP as a tool to provide resources and information to help build innovative and creative solutions to adapt to that uncertain future. I applaud the work and collaboration between Wyoming water users and stakeholders, Wyoming SEO staff, Reclamation, and UCRC staff to improve the program for 2024.”
Today, Governor Polis and the Colorado Water Conservation Board (CWCB) announced the launch of the second year of Transformative Landscape Change (TLC) Challenge program, which challenges local communities to reimagine their public spaces and embrace waterwise landscaping. The effort, a partnership with the nonprofit Resource Central, is designed to convert water-intensive landscapes into climate-appropriate, low-water-use, and attractive spaces.
“Protecting our precious water resources is critical to ensuring a strong future for Colorado and our economic industries like agriculture and outdoor recreation. This challenge will help innovate, conserve water in our communities, and promote stewardship around the state,”said Governor Jared Polis.
“Water conservation continues to be an important and comparatively cost-effective tool for increasing state and local water security and resilience,” says Russ Sands, CWCB Water Supply Planning Section Chief. “The TLC Challenge will help communities replace up to 2,500 square feet of nonfunctional turf with the types of low-water landscape plants that better serve our communities in hopes that it can inspire larger turf replacement efforts.”
The CWCB and Resource Central worked on an earlier TLC Challenge with three communities across Colorado in 2023 to transform public spaces and inspire communities to install low-water plants instead of high-water-use turf. This round will expand the TLC Challenge and increase the number of projects accepted to increase the impact. Eligible entities include local governments and municipal water providers. The funding is not available to residential or commercial property owners.
The effort complements CWCB’s 2023 Turf Replacement Program efforts, which provided funding to 50 eligible entities in Colorado to reduce nonfunctional turf and increase sustainable landscapes.
Eyes across the state are on sustainable landscape development efforts like this. Governor Polis signed Senate Bill 24-005 on Friday, March 15, which limits the installation of nonfunctional turf on commercial, industrial, and institutional properties, state facilities, and spaces, including medians and parking lots.
“But the hard work of removing nonfunctional turf where it’s already been installed also needs to continue,” says Sands.
“Replacing turf with waterwise landscapes helps cities conserve water supplies, meet the vision of the Colorado Water Plan, and maximize the ecosystem benefits of our landscapes,” said Lauren Ris, CWCB Director.
The Colorado Water Plan projects up to 740,000 acre-feet of future municipal water needs per year.
“To reduce our water demands, Colorado needs a suite of conservation tools, including water conservation programs and water pricing structures that help shape what our cities look like and how we develop,” says CWCB expert Jenna Battson. “Having land use codes and ordinances that align with these efforts is critical because the last thing we want is for codes to reinforce installing the same types of high-water vegetation that we are paying to remove.”
Converting water-intensive landscapes to waterwise spaces allows everyone to be part of the solution. CWCB and Resource Central are working together through the TLC Challenge to help inspire responsible landscape development and increase engagement with water-saving practices.

The competitive application window is open now and will close on June 1, 2024. Awardees will be evaluated based on the merits of their application. After selected recipients are notified, they will work with Resource Central to implement projects in the late summer of 2024 or early spring of 2025.
Eligible entities include local governments and municipal water providers. The funding is not available to residential or commercial property owners. Resource Central will work with the selected applicants to design the new space, remove and compost the turf, and provide customized Garden In A Box plants as well as irrigation and maintenance planning for the new landscape.
Applications that demonstrate potential water savings, public benefits that include equity, and educational components will be more competitive. By prioritizing project proposals that demonstrate strong community engagement strategies, well-defined goals, and measurable outcomes, CWCB and Resource Central can ensure the biggest impact with the funding. Communities without an existing turf replacement program will be prioritized to help increase local examples of landscape transformations; however, all eligible applicants are encouraged to apply.

March 18, 2024
Bill signed into law on Friday makes thirsty imported grasses a no-no in new road medians and other public places that rarely see human feet. Native grasses OK.
The remarks in the office of Colorado Gov. Jared Polis on Friday afternoon were brief, befitting the bill that was soon to be signed into law, the state’s most aggressive effort yet to curb water allocated to urban landscaping.
“We want folks to be part of the solution around water and to reduce the water needs of their non-functional turf, ranging from Colorado-scaping and xeriscaping to lower-water solutions with different types of grasses that may require less water,” said Polis of SB24-005.
Taking the lectern, Sen. Dylan Roberts, a prime sponsor and a Democrat who represents much of northwestern Colorado, noted an irony. It had snowed hard the previous day along the northern Front Range, where about 75% of Coloradans live, and the snow was extremely wet, even for March.
“It’s funny, with all the snow right now, you might not think that we have to deal with a lot of water scarcity, but we do,” said Roberts, a Frisco resident.
“We know that in Colorado we face a historic drought and we need to put in place every single common-sense tool to save water that we can. And this is one of those.”
Colorado in 2022 began incentivizing removal of what is commonly called non-functional turf. The phrase means imported grass species with high water requirements that typically get almost no use. A legislative allocation of $2 million resulted in grants to about three-dozen communities across Colorado but especially in Front Range cities where 85% of the state’s residents live.
In September 2023, the Colorado Water Conservation Board awarded a $1.5 million grant to Boulder-based Resource Central. The nonprofit was formed in 1976 to encourage conservation. In 2023, it completed 604 lawn-replacement projects along the Front Range. Its marquee program, Garden In A Box, provides low-water plants and has partnerships with several dozen municipalities along the Front Range. The state grant will allow Resource Central to expand its programming to the Western Slope.
In October 2023 a year-round legislative water committee that is chaired by Roberts heard a proposal from Denver Water, Western Resource Advocates and others. That proposal was the basis for the new law.
Instead of incentives to change, the new law draws lines of restraint. Beginning in 2026, local governments can no longer allow the installation, planting or placement of non-functional turf, artificial turf, or invasive plant species. This applies to commercial, institutional, and industrial properties, but also common-interest community property. Read that as HOAs.
Also verboten will be planting of non-functional turf in street rights-of-way, parking lots, median or transportation corridors.

The law applies to new or redeveloped state facilities beginning in 2025.
Imported species such as Kentucky bluegrass can use twice as much water as native grass. Native species such as buffalo and blue gamma or species hybridized for arid conditions will be allowed.
Several Colorado jurisdictions have gone further. Aurora and Castle Rock in 2022 both adopted limits to residential water use for landscaping. The state law does not touch water use at individual homes. The two municipalities both expect substantial population growth but have limited water portfolios for meeting new demand.
Other municipalities and water providers from Broomfield to Grand Junction have also adopted laws crowding out water-thirsty vegetation. Their motives vary but all are premised on Colorado’s tightening water supplies. Cities use only 7% of the state’s water, and roughly half of that goes to landscaping.
Yet developing new sources of water requires going farther afield, usually converting water from agriculture, and can become very expensive. Consider plans by Parker Water and Sanitation District and Castle Rock. They are planning a pipeline to the Sterling area in coming years with a new if smallish reservoir near Akron. In this case, the project has support from an irrigation district in the Sterling area, but all this new infrastructure comes at a great expense.
The bill faced no major opposition in the Legislature, although most House Republicans — nearly all from rural areas — voted against it.
During her time at the microphone, Rep. Karen McCormick, a Democrat from Longmont, emphasized the need to define what constitutes non-functional turf.
“Coming up with those terms of functional versus non-functional turf was really important so that the people of Colorado understand that the choices that we have in these spaces (can result in) beautiful, Western drought-tolerant grasses and bushes and flowers.” she said.
State Rep. Barbara McLachlan, a Democrat from Durango, emphasized cost savings as well as water savings. “If you’re not having a picnic on that little piece of turf or having a soccer game, you probably don’t need to be spending the water and money it takes to keep that alive.”
Sen. Cleave Simpson, a Republican from Alamosa who represents much of southwestern Colorado and the fourth prime sponsor, was not present for the bill-signing.

Those present for the bill signing included Denver Water’s Alan Salazar, the chief executive, and Greg Fisher, the manager of demand planning.
A Denver Water staff member decades ago had invented the word “xeriscaping” but the agency had never put much muscle into curbing water use. After all, it had a flush water portfolio. The thinking as explained in Patty Limerick’s book about Denver Water, “A Ditch in Time,” was that if drought got bad enough, the agency could always squeeze residential use for water, as it did in the severe drought summer of 2002.
With new leadership and a worsening story in the Colorado River Basin, Denver had altered its thinking. The city – which provides water for about 1.6 million people, including many of the city’s suburbs – gets roughly half of its water from transmountain diversions. That statistic holds true for the Front Range altogether. Denver’s water rights are relatively senior, but they’re junior to the Colorado River Compact of 1922.
That compact assumed far more water in the river than occurred in most of the 20th century. Flows during the 21st century have diminished, at least in part due to intensifying heat. That heating – and drying – will very likely worsen in coming decades. While Colorado accurately claims that it has not used its full allocations under river compacts, there’s the underlying and shifting hydrology that argues against any certainty.
The city this year will partner with Resource Central, a first, to encourage transformation of front yards with high water demands into less-needy landscapes.
Lindsay Rogers, a water policy advisor for Western Resource Advocates, said the key work during the next couple of years will be to work with local jurisdictions to implement the new law.
“Not only that, they’ll need to figure out how they’re going to enforce their new landscaping standards. And if they do that well, this bill will be hugely impactful.”
She said this bill should be understood as being part of a “growing understanding that everyone needs to do their part to conserve. There are lots and lots of opportunities across the land-use development spectrum.”
At least some of those ideas can be found in a report by a state task force issued in late January. Polis had appointed the 21-member group a year before and gave it the job of examining what steps Colorado could take to reduce water devoted to urban landscaping.
After seven meetings, the task force issued a report in late January that concluded that “the time to rethink our landscapes is now.” It provided 10 recommendations.
Topping the recommendations was a statement in accord with the new law. The task force also called for continued support of turf replacement in existing development, promotion of irrigation efficiency and encouragement of pricing mechanism that steer decisions that promote water conservation.
Considering that it took well more than a century to install the existing urban landscapes, this shift will not be accomplished in a few short years. The climate could shift to produce more water for Colorado, but the warming atmosphere would almost certainly steal those gains.
In short, the water scarcity driving this new law is not going away.

The two groups of Colorado River watershed states — the Upper Basin and the Lower Basin — have each come up with a respective preliminary plan for how to deal with a shrinking supply of water in the river and its tributaries. And, surprise surprise, they don’t agree: They both want the other team to take a bigger hit.
Way back in early 1900s, the question facing these seven states was how to divide up the waters of the Colorado River, first between the two basins, then between the states within each basin. The 1922 Colorado River Compact answered that question. Sort of. The Compact is flawed in many ways, including that the folks who signed onto it thought there was a bunch more water than actually flowed in the river — even back then.
I like to run this one again from time to time, just to remind folks how much the population of the West has grown over the last century. This is what the signers of the Colorado River Compact were dealing with as far as water users go — compared to some 40 million users now. Source: USGS.
Now there’s even less water and higher consumption. If the river users don’t make some major cuts and soon, the reservoirs will dry up and leave the Southwest’s cities, towns, and farms to fight over the diminishing scraps.
“We can no longer accept the status quo of the Colorado River operations,” said Becky Mitchell, Colorado’s representative on the Upper Colorado River Commission, in a press release. “If we want to protect the system and ensure certainty for the 40 million people who rely on this water source, then we need to address the existing imbalance between supply and demand.”

So now the question facing the states is similar to the one they asked 102 years ago, but with a twist: How should those deep cuts be divided up now that global heating is depleting the river’s flow?
It’s a tough question with no easy answers. And it’s all made more difficult by a lack of clarity regarding the definition of terms in the original Compact such as “beneficial consumptive use” and “surplus,” and how to measure those things. Where does use of tributaries that run into the Colorado below Lee Ferry, such as the Gila River, the Little Colorado, and the Virgin River fit into all of this?
The “natural flow” is the estimated amount of water that would flow past Lee Ferry (below Glen Canyon Dam) if there were no upstream dams, diversions, or withdrawals. The Colorado River Compact was based on the assumption that about 16 million acre-feet flowed past Lee Ferry per year (which is not unreasonable given the abnormally high flows between 1906 and the late 1920s). In fact, the 1906-1923 median is about 14.5 MAF (with an average of about 14.7 MAF). And the 1991-2023 average is 13.2 MAF. Yikes! Source: Bureau of Reclamation.
Until those definitions are agreed upon, we won’t really know whether the Lower Basin is using the amount of water allocated to it in the Compact (8.5 million acre-feet), or significantly more than that (10.1 million acre-feet). Until we know what “surplus” means, we won’t know who is responsible for ensuring Mexico gets its allocated share. So far there is no agreement on those definitions. (For a detailed and intelligent take on this, please see Eric Kuhn’s and John Fleck’s piece on Fleck’s Inkstain blog).
The good news is that the current proposals aren’t final; there is still time for the basins to negotiate. And the two basins’ representatives are inching closer to accord, finding harmony where it previously eluded them. The two alternatives agree:
That consumption cuts should be triggered not by forecasted water levels in Lake Mead, but by current hydrologic conditions throughout the entire system. However, they differ on how to measure those conditions.
And that the Lower Basin should include evaporation and seepage — totaling an estimated 1.3 million acre-feet per year — in its consumptive use, as the Upper Basin has always done. They plan to offset this loss by cutting consumption by 1.5 million acre-feet per year.

The main sticking point comes when reservoirs shrink to critically low levels:
Under the Upper Basin’s plan, as storage levels drop, they would release progressively less water from Lake Powell. So if water storage is 81% to 100% full, then they’d release 8.1 to 9 MAF from Glen Canyon Dam, giving the Lower Basin their full allocation. But if storage is less than 20% full, it would release just 6 MAF per year, giving the Lower Basin 2.5 MAF less than their allocation that year — presumably forcing them to cut that same amount of consumption. Whether and how much consumption the Upper Basin would have to cut under this scenario would depend on how much water is actually in the river. It’s important to note that the Upper Basin does not and has never used its full allocation of 7.5 MAF per year.
Under the Lower Basin’s plan, when the system is between 38% and 70% full, the Lower Basin would cut its consumption by 1.5 MAF per year. When system water levels drop below that, then the Lower Basin would continue its 1.5 MAF per year cuts, and the two basins would share any cuts above that up to a maximum of 3.9 MAF per year. So under the maximum cuts, the Lower Basin would reduce usage by 2.7 MAF while the Upper Basin would cut use by 1.2 MAF.

The Lower Basin’s proposed framework for reductions. The Lower Basin would make all of the cuts (1.5 MAF per year) down to 38%, after which the two basins would evenly split any reductions beyond 1.5 MAF. Source: Lower Basin states.
Both basins’ alternatives mention and acknowledge that many tribal nations’ water rights remain unfulfilled, and yet say little about how the situation might be rectified. And each Basin says its respective plan is the most sustainable, is most likely to keep Hoover and Glen Canyon dams from being compromised, and complies with the Law of the River — or the set of treaties, compacts, and court cases that govern how the river is used.
Yet the sustainability or health of the Colorado River as an entity — a breathing, flowing, living being — is barely mentioned. Little thought is given to the ecosystems, cultures, and creatures the river sustains. I realize that’s not the point of this exercise. And yet, ultimately, it will be the River itself that lays down the law, not century-old compacts or legal precedents or antiquated water rights. Perhaps we ought to pay it a little more respect.
“New plot using the nClimGrid data, which is a better source than PRISM for long-term trends. Of course, the combined reservoir contents increase from last year, but the increase is less than 2011 and looks puny compared to the ‘hole’ in the reservoirs. The blue Loess lines subtly change. Last year those lines ended pointing downwards. This year they end flat-ish. 2023 temps were still above the 20th century average, although close. Another interesting aspect is that the 20C Mean and 21C Mean lines on the individual plots really don’t change much. Finally, the 2023 Natural Flows are almost exactly equal to 2019. (17.678 maf vs 17.672 maf). For all the hoopla about how this was record-setting year, the fact is that this year was significantly less than 2011 (20.159 maf) and no different than 2019” — Brad Udall

The U.S. Bureau of Reclamation set a deadline of Monday for the seven states to come up with plans, but a hoped-for joint plan was not in the cards. By the end of 2024, the Bureau of Reclamation anticipates having what’s called a draft “environmental impact statement” that will present alternatives for how the Colorado River will operate in the decades to come. Those new guidelines will also determine the management and facilities of the two reservoirs, as well the Hoover and Glen Canyon dams…
Upper Basin plan
The plan submitted by the Upper Basin states calls for the following:
• A commitment from the Upper Basin states to help preserve the ability to make releases from Lake Powell, the nation’s second-largest reservoir that provides power through the Glen Canyon dam
• For Lake Powell: Modeled releases from Lake Powell that are based on hydrologic conditions and designed to rebuild storage to protect Lake Powell’s ability to make releases consistent with the Law of the River, as dictated by the 1922 Colorado River compact
• Lake Mead: Modeled Lower Basin operations adapted from a concept first provided by the Lower Basin States based on the combined storage of Lake Powell and Lake Mead…
The Lower Basin plan
Tom Buschatzke, the director of the Arizona Department of Water Resources and the state’s principal negotiator on matters relating to the Colorado River, said while he has not yet fully examined the upper division states’ alternative plan, he told Colorado Politics he is disappointed by what he’s seen so far.
• Addresses the structural deficit in the Lower Basin
• Operates the reservoirs based on system contents, rather than elevations at Lake Powell and Lake Mead
• Shared water use reductions broadly
• Creates provisions for the storage and delivery of stored water
• Releases from Lake Powell that are adaptable to a broad range of hydrology and “hydrologic shortages”
The alternative dictates cuts calculated by state — every state, not just those in the Lower Basin — depending on how much the levels drop at Lake Mead.

Coloradans gunning to join this year’s effort to save water in the Colorado River Basin could help conserve up to 17,000 acre-feet of water — much more than the 2,500 acre-feet saved in 2023 — and receive about $8.7 million in return.
The voluntary, multistate program pays water users to temporarily use less water. State and federal officials relaunched the effort, called the System Conservation Pilot Program, in 2023 in response to federal calls to cut back on water use in the drought-stressed river basin. After a stumbling relaunch in 2023, this year’s program is moving forward with more applications, more potential water savings and more money for participants.
“The changes this year — it was just much more transparent,” said Greg Vlaming, a consultant who helped nine growers apply to the program. “The application process was simple and easy. It took me less than 15 minutes per application.”
The conservation program was initially piloted from 2015 to 2018. In 2023, officials relaunched it with $125 million in federal funding as a way to cut back on water use in response to a looming water supply crisis in the Colorado River Basin. The basin supplies water for 40 million people across the western U.S., 30 Native American tribes and northern Mexico.
Interest in the program has grown steadily. During the four-year pilot, about 15 to 45 people applied each year. In 2023, the program received more than 80 applicants.
But program costs have grown as well, in part because the program’s managers have boosted reimbursement rates to keep up with rising crop prices, according to the Upper Colorado River Commission, which oversees the program.
Last year, the four Upper Basin states — Colorado, New Mexico, Utah and Wyoming — spent nearly $16.1 million in federal funding to conserve about 37,810 acre-feet of water. During the four-year pilot, the program spent half that amount, about $8.5 million, to conserve more water, about 47,000 acre-feet.
One acre-foot supports about two families of four to five people for one year.
This year’s application period closed in December with 124 applications, according to the Upper Colorado River Commission. Of those, Colorado water users submitted 56; Utah, 32; New Mexico, one; and Wyoming, 35.
The river commission, which includes representatives from the federal government and each of the Upper Basin states, is scheduled to consider the applications March 4.
Then, once a federal review is complete and all project details are finalized, applicants have the final say about whether they will participate. The commission aims to launch the conservation projects in April, said Executive Director Chuck Cullom.
In Colorado, most of the applications come from farmers and ranchers who proposed cutting their water use by temporarily fallowing fields, or by switching to crops that use less water or can better withstand drought. About 20 proposals aim to save enough water to warrant $100,000 or more in compensation per project.

The Ute Mountain Ute Farm and Ranch in southwestern Colorado proposed the state’s biggest project this year. If approved, the enterprise will use crops that require less water and will fallow nearly 900 acres of land for an estimated 2,172 acre-feet of water savings. It would receive $1.1 million in return.
David Harold, owner of the Tuxedo Corn Company in Olathe, proposed saving 600 acre-feet of water. In return, he’d get about $305,000, roughly equivalent to the cost of a nice tractor, he said.
The program asks farmers to cut down their water use — buy-and-dry under a different name — but it’s also a way to experiment, he said. How can he respond to an uncertain water supply with as little impact to the local economy as possible and still survive as a farmer?

Harold chose not to fallow — not growing crops means fewer hands to help with production and that impacts the local economy. Instead, he decided to turn off irrigation when it was hottest and least efficient, and to grow more drought resistant crops, like Kernza and sainfoin.
The payment was enticing, but in the long term not enough to offset all of the uncertainties that farmers face, he said. The conservation program’s reimbursement rate could change, or the program could end. There was a disaster with corn earworm in the sweet corn industry last season. State regulations, water supplies and labor costs change.
“The list goes on and on and on of why I should be doing everything I can to diversify or maneuver. Be agile. Be thoughtful,” Harold said. “The past will not be the future; what my dad did is not likely what’s going to work for me. It’s kind of daunting out there.”

Pueblo Water was the only municipal water provider to apply. The Front Range utility normally takes about 943 acre-feet of water from the Ewing Placer Ditch in the Colorado River Basin and diverts it into the Arkansas River Basin for homes and gardens around Pueblo. If accepted, it will leave all of that water in the Colorado River Basin in return for up to $479,987.
“The primary purpose we’re doing it is just because we think, for this particular year, the water’s going to be more valuable in the System Conservation Pilot Project than it’s going to be on the Arkansas River,” said Alan Ward, division manager of water resources for Pueblo Water. “I don’t think we have plans to dedicate it (the funding) to any specific purpose. Essentially what it does is it subsidizes the cost of water for our customers.”
In 2023, when participants negotiated their own reimbursement rates, compensation for the top five applicants ranged from about $70,000 to $195,000 per project, according to the Colorado Water Conservation Board.
In response to participant feedback, officials this year switched to a fixed-rate structure based on a market analysis by the federal and state governments.

Colorado participants will receive $509 per acre-foot of saved water, the highest compensation rate of the four Upper Basin states. New Mexico producers will receive $300, while those in Utah and Wyoming will receive $506 and $492, respectively. Reimbursement rates will vary for other projects, like leaving water storage in reservoirs, or municipal and industrial water savings.
“I’m not complaining about it,” Vlaming said. “But when I say $509 per acre-foot to guys, they’re like, ‘Where do I sign?’ Some of these guys are going to get paid quite well.”
For water users, negotiating their own rates was one of several problems with last year’s program, alongside a short application period and unclear communication about how to apply and how water savings were calculated.
The application process was much more streamlined this year because officials learned from the process in 2023, said Cullom, the Upper Colorado River Commission executive director.
“The process — which included pre-application interviews and discussions between the applicant and the states and the consultants — helped strengthen all the applications,” he said. “I think we improved the process. That’s some feedback we’ve heard.”

Minor pushback to proposed limits on new water-thirsty grasses in areas that get little or no foot traffic
This story was produced as a collaboration between Big Pivots and Aspen Journalism — two nonprofit news organizations covering Colorado’s water. It follows a five-part series that examined the intersection of water and urban landscapes in Colorado.
Colorado legislators in 2022 passed a bill that delivered $2 million to programs across the state for removal of turf in urban areas classified as nonfunctional. By that, legislators mean Kentucky bluegrass and other thirsty-grass species that were meant to be seen but rarely, if ever, otherwise used.
Now, they are taking the next step. The Colorado Senate on Tuesday voted in favor of a bill, Senate Bill 24-005, that would prevent thirsty turf species from being planted in certain places that rarely, if ever, get foot traffic, except perhaps to be mowed.
Those places include alongside roads and streets or in medians, as well as in the expansive areas surrounding offices or other commercial buildings, in front of government buildings, and in entryways and common areas managed by homeowners associations.
The bill also bars use of plastic turf in lieu of organic vegetation for landscaping.
“If we don’t have to start watering that turf in the first place, we never have to replace it in the future,” state Sen. Dylan Roberts, D-Frisco, a co-sponsor, said in making the case for the proposed new state standard.
Roberts stressed that the prohibition would not apply to individual homes or retroactively to established turf. “It applies to new development or redevelopment. It does not apply to residential homes,” he said. “This is about industrial, commercial and government property across the state.”
Kentucky bluegrass and other grass species imported from wetter climatic zones typically use far more water than buffalo grass and other species indigenous to Colorado’s more arid climate. The bill, however, does allow hybrids that use less water as well as the indigenous grass species.
Originally reviewed by an interim legislative committee in October, the bill was subsequently modified to provide greater clarity about what constitutes functional versus nonfunctional turf, while giving towns, cities and counties greater flexibility in deciding which is which within their jurisdictions. If the bill becomes law, local jurisdictions will have until Jan. 1, 2026, to incorporate the new statewide standard into their landscaping code and development review processes.
After being approved on a third reading by the Senate by a 28-5 vote on Wednesday morning, the measure now moves to the House.
Advocates do not argue that limits on expansion of what the bill calls nonfunctional turf will solve Colorado’s water problems. Municipalities use only 7% of the state’s water, and outdoor use constitutes roughly half of municipal use.
“One more tool in the toolbox,” Roberts said.
State Sen. Cleave Simpson, R-Alamosa, said if the standard had been adopted 20 to 30 years ago, perhaps 10,000 acre-feet of water could have been saved annually.
“As a percentage, it is minimal,” he conceded. “It’s closing the gaps in small increments as best you can as opposed to large sweeping change.”
The backdrop for this is more frequent drought and rising temperatures since 2002, what Simpson called the aridification of the West. The climatic shift is forcing harder choices.
“We are all trying to figure out how to live and work in this space,” Simpson said.
In a Senate Agriculture and Natural Resources Committee meeting Jan. 25, Simpson also said he was motivated to help prevent water grabs by Front Range cities from the San Luis Valley, what locals sometimes call Colorado’s south slope. Three separate attempts have been made in the past 35 years to divert water from the San Luis Valley, a place already being forced to trim irrigated agriculture to meet requirements of the Rio Grande Compact.
“That’s largely my motivation to be part of this conversation and do everything I can to reduce that pressure on my rural constituents and our way of life,” Simpson said in the committee hearing. The bill passed the committee on a 4-1 vote.
Developing water for growing cities — particularly along the Front Range but even in headwaters communities — has become problematic as the climate has veered hotter and, in most years of the 21st century, drier.
The result, as was detailed in a five-part collaboration in 2023 between Big Pivots and Aspen Journalism, has been a growing consensus about the need to be more strategic and sparing about use of water in urban landscapes.
Agriculture uses nearly 90% of the state’s water, as was noted by state Sen. Chris Hansen, D-Denver. At Tuesday’s Senate hearing, he chided Roberts, Simpson and other legislative sponsors for not addressing efficiency in agriculture.
Hansen, who grew up in a farm town in Kansas near the Colorado border, applauded the bill but questioned why the interim committee hadn’t come up with legislation to improve efficiency of agricultural water use. He cited the use-it-or-lose-it provision of Colorado water law that he suggested discouraged farmers and ranchers from innovating to conserve water.
“I feel the interim water committee let us down by not bringing forth anything that advances conservation on what is by far the largest category of use, almost 90%,” he said. “I want to know what is next on that front.”

Hansen got strong pushback. Simpson responded that agriculture in the San Luis Valley has already been forced to change. To comply with the Rio Grande Compact, his district is trying to figure out how to take 10,000 to 20,000 acres out of agricultural production. On his own farm, he said, water deliveries that traditionally lasted until mid-July have ended as early as May 20. “I have to figure out a way to grow crops that are less water-consumptive, more efficient and ultimately take irrigated acreage out of production,” Simpson said.
State Sen. Byron Pelton, R-Sterling, also took the occasion to cite incremental gains in irrigation efficiency and the loss of production in the Republican River basin. There, roughly 25,000 acres need to be taken out of production for Colorado to meet interstate compact requirements.
As had been the case several days before at the bill’s legislative committee hearing, most of the limited opposition in the Senate was against the notion that cutting water used for landscaping is a statewide concern. It’s a familiar argument — a preference for local control — used in many contexts.
A representative of the Colorado Municipal League (CML), a consortium of 270 towns and cities, told the Senate committee that the proposal constituted state overreach in a one-size-fits-all approach.
Heather Stauffer, CML’s legislative advocacy manager, cited the regulations of Aurora, Greeley and Aspen as examples of approaches created to meet specific and local needs. “We would advocate that the state put more money into funds that address turf removal programs that have been very successful among municipalities across the state,” Stauffer said.
In 2023, Boulder-based Resource Central completed 604 lawn-replacement projects along the Front Range. With aid of state funding, it plans to expand its turf-removal and popular Garden In A Box programs to the Western Slope this year.
No representatives from any towns or cities showed up to oppose the bill. But representatives of three local jurisdictions, including Vail-based Eagle River Water and Sanitation District and the water provider for unincorporated Pueblo West, testified that the bill filled a need.
Denver is behind the bill. Denver Water, which provides water to 1.6 million people, including the city’s 720,000 residents as well as many suburban jurisdictions, has committed to reducing the water devoted to urban turf in coming years by 30%, or roughly the turf covering 6,000 acres. Utility representatives have said they don’t want to become frugal with water devoted to existing landscapes only to see water used lavishly in new development.
Andrew Hill, government affairs manager for Denver Water, called the bill a “moderate approach” in creating a new waterwise landscaping standard, one in which imported grasses are not the default.
“It makes real changes statewide, but it’s narrow enough to only apply to areas [where] I think a consensus exists,” Hill said at the committee hearing.

Local governments can go further, and many have already. Thirty-eight local governments and water providers in Colorado offer turf-replacement programs. Western Resource Advocates found last fall that 17 of the jurisdictions already limit new turf while another nine plan to do so.
Aurora and Castle Rock, late-blooming municipalities in the metropolitan area, have adopted among the most muscular regulations in Colorado, taking aim at water devoted to new homes’ front yards. Both expect to continue growing in population, and together they plan to pursue importations of water currently used for farming along the South Platte River in northeastern Colorado. Aurora also still owns water rights in the Eagle River basin that it has been trying to develop for the past 40 years.
In the full Senate debate, Republican leaders argued for incentives, such as the expanded buy-back program for turf removal, instead of a statewide thou-shalt-not approach.
The Colorado River Drought Task Force recommended legislators allocate $5 million annually for turf-removal programs. Key legislators have already indicated they plan to introduce legislation to do just that.
But is this the answer? Such programs are “inefficient and not cost-effective” if water-thirsty grass species continue to be planted in questionable places, the policy manager for municipal conservation at Western Resource Advocates said in the committee hearing last week.
The policy manager, Lindsay Rogers, said passing the bill would build the momentum to “help ensure that Coloradans live within our water means and particularly in the context of a growing state and worsening drought conditions.”
The Associated Landscape Contractors of Colorado, which represents 400 Colorado landscape and supplier companies, testified in support of the bill but hinted at future discussions as the bill goes through legislative sausage-making. Along with sod growers, they quibble over the dichotomous phrasing of nonfunctional versus functional turf. They prefer the words recreational and utility.
On the flip side of these changes, some home gardeners might find buffalo grass and other indigenous grasses more conserving of water but less appealing. Buffalo grass, for example, greens up a month or so later in spring and browns up a month earlier in fall.
Water in urban landscapes is also on the agenda for three programs this week at the annual meeting of the Colorado Water Congress, the state’s preeminent organization for water providers. Included may be a report from a task force appointed by Gov. Jared Polis last February that met repeatedly through 2023 to talk about ways to reduce expansion of water to urban landscapes.

Relatively minor pushback in Colorado Senate to proposed limits to new water-thirsty grasses in urban areas that get little or no foot traffic
Colorado legislators in 2022 passed a bill that delivered $2 million for programs across the state for removal of thirsty turf classified as non-functional, meaning that the grass is mainly ornamental, to be seen but not otherwise used.
This morning [January 30, 2024] the Colorado Senate will review a bill that, if approved, will extend the concept.
“This bill is about not putting (in) that non-functional turf in the first place,” explained Sen. Dylan Roberts, D-Frisco, in introducing SB24-005 to the Senate Agriculture and Water Committee last Thursday. “If you don’t put it in the first place, you don’t have to replace it.”
The committee approved the bill, titled “Prohibit Landscaping Practices for Water Conservation,” in a 4-1 vote.
The Colorado Municipal League registered opposition, but tellingly, no representatives of towns or cities showed up to argue against the bill. Instead, support was expressed by representatives of several local jurisdictions, including the Eagle River Water and Sanitation District, the second largest water provider on the Western Slope, as well as the special district that provides water for Pueblo West.
The bill takes aim at Kentucky bluegrass and other species imported from wetter climatic zones that are planted along streets and in medians, amid parking lots, in front of government buildings as well as the expanses you often see around office parks and many business and industrial areas. The imported species can use far more water than buffalo grass and other species indigenous to Colorado’s more arid climate.
Residential property is unaffected. Worried about a public backlash, legislators amended the bill to make that exemption doubly clear.
The bill also bars use of plastic turf in lieu of organic vegetation for landscaping.
Originally reviewed by an interim legislative committee in October, the bill was subsequently modified based on input of stakeholders. Functional and non-functional turf were clarified. The bill was also modified to give cities and counties flexibility to determine areas of “community, civic and recreational” turf grasses, in effect letting them decide what is functional in some instances. The revised bill language also made it clear that installing native species of grass or those hybridized species that use less water would be OK. The revised bill also give municipalities and counties until Jan. 1, 2026, to review and revise their landscaping code and development review processes.
Part of the impetus to reduce water devoted to urban landscapes is a desire to protect water for agriculture in the San Luis Valley and other farm areas of Colorado. Photo/Allen Best
Sen. Cleave Simpson, R-Alamosa, a co-sponsor, called the bill a “natural extension” of the turf-buy-back bill from 2022. He said he was surprised at the reaction in Alamosa to that funding. The water district he manages began getting inquiries about how to participate. “It kind of inspired me that there’s more room for improvement here in this space,” he told committee members.
Simpson also said he was motivated to help prevent water grabs by Front Range cities from the San Luis Valley, what locals sometimes call Colorado’s South Slope. Three separate attempts have been made in the last 35 years to divert water from the San Luis Valley, a place already being forced to trim irrigated agriculture as necessary to meet requirements of the Rio Grande Compact.
“That’s largely my motivation to be part of this conversation and doing everything we can to reduce that pressure on my rural constituents and our way of life,” said Simpson.
Nobody argues that the limits on expansion of what the bill calls non-functional turf will solve Colorado’s water problems. Municipalities use only 7% of the state’s water, and outdoor use constitutes roughly half of municipal use. Agriculture uses nearly 90% of the state’s water.
But developing water for growing cities, particularly along the Front Range but even in the headwaters’ communities, has become problematic as the climate has veered hotter and, in most years of the 21stcentury, drier.
The result, as was detailed in a five-part collaboration during 2023 between Big Pivots and Aspen Journalism, has been a growing consensus about the need to be more strategic and sparing about use of water in urban landscapes.
Disagreements remain about whether the state should create a state-wide standard, as is proposed in this legislation, or whether local governments should figure out their own solutions.
It’s a familiar arguing point in Colorado, but rarely are the divisions neat and simple. That’s also true in this case. Colorado Springs, the state’s second largest city, has a robust program for urban landscape transformation but was hesitant about the bill’s approach, wanting to ensure local flexibility.
Denver is fully behind the bill. Denver Water, which provides water to 1.6 million people, including the city’s 720,000 residents as well as many suburban jurisdictions, has committed to reducing the water devoted to urban turf in coming years by 30%, or roughly 6,000 acres. It says it doesn’t want to become parsimonious with its water only to see water used lavishly in new settlements.
Andrew Hill, the government affairs manager for Denver Water, called the bill a “moderate approach” in creating a new waterwise landscaping standard, one in which imported grasses are not the default.
“It makes real changes statewide, but it’s narrow enough to only apply to areas (where) I think a consensus exists,” said Hill at the committee hearing.
Local governments can go further, and many have already. Colorado has 38 turf replacement programs, and Western Resource Advocates found last fall that 17 of the jurisdictions already limit new turf and another 9 plan to do so.
Aurora and Castle Rock, late-blooming municipalities in the metropolitan areas, have adopted among the most muscular regulations in Colorado, even taking aim at water devoted to front yards. Both expect to continue growing in population, and together they plan to pursue importations of water currently used for farming along the South Platte River in northeastern Colorado. Aurora also still owns water rights in the Eagle River that it has been trying to develop for the last 40 years.
The Colorado Municipal League, a consortium of 270 towns and cities, insists that the proposal represents state overreach of one-size-fits-all policies for local landscapes. Heather Stauffer, CML’s legislative advocacy manager, cited the regulations of Aurora, Greeley, and Aspen as examples of approaches created to meet specific and local needs.
“We would advocate that the state put more money into funds that address turf removal programs that have been very successful among municipalities across the state,” Stauffer said. In 2023, Boulder-based Resource Central completed 604 lawn-replacement projects along the Front Range. With aid of state funding, it plans to expand its turf-removal and popular Garden In A Box programs to the Western Slope this year.

Witnesses at the committee hearing repeatedly echoed what Roberts said in introducing the bill. Paying for turf removal is “inefficient and not cost-effective” if water-thirsty grass species continue to be planted in questionable places said Lindsay Rogers, policy manager for municipal conservation at Western Resource Advocates, which helped shape the bill.
Rogers said passing the bill would build the momentum to “help ensure that Coloradans live within our water means and particularly in the context of a growing state and worsening drought conditions.”
The Associated Landscape Contractors of Colorado, which represents 400 Colorado landscape and supplier companies, testified in support of the bill but hinted at future discussions as the bill goes through legislative sausage-making. Along with sod growers, they quibble over the dichotomous phrasing of “non-functional vs functional turf. They prefer the words recreational and utility.
On the flip side of these changes, some home gardeners might well find buffalo and other indigenous grasses, if more conserving of water, less appealing. Buffalo grass, for example, greens up a month or so later in spring and browns up a month earlier in autumn.
Water in urban landscapes is also on the agenda for three programs this week at the annual meeting of the Colorado Water Congress, the state’s preeminent organization for water providers. Included may be a report from a task force appointed by Gov. Jared Polis last February that met repeatedly through 2023 to talk about ways to reduce expansion of water to urban landscapes.
The city of Greeley launched a multi-language survey to gather thoughts on designing a new water conservation program to fit everyone’s needs, according to a city news release. City officials will also host a pair of community workshops to engage with residents and bridge the gap between the city and its water users.
“We want our conservation programs to serve all water users in our growing and diverse community,” Water Conservation Specialist Rita Jokerst said in the release. “And we’re excited to use this survey to hear from as many residents as possible.”
Residents can enter to win one of three $100 gift cards by filling out the survey at greeleygov.com/LILAC or by attending one of the two come-and-go community workshops. The first will be hosted from 4-7 p.m. Jan. 23 at the Greeley Recreation Center, 651 10th Ave. The second will take place from 5:30-7:30 p.m.Feb. 21 at the LINC Library, 501 8th Ave. Greeley Water Efficiency Resource Coordinator Margarita Padilla said she is excited about the survey and looks forward to engaging with the community…

California’s Colorado River Board said Wednesday [December 13, 2023] that several water agencies and one tribal nation signed the first in a series of agreements that will conserve up to 1.6 million acre-feet of water. The agreements build on previous commitments by California, Arizona and Nevada to reduce water use by 3 million acre-feet over three years, cutting usage by about 14% across the Southwest. Much of the reductions are occurring in exchange for payments funded through the Inflation Reduction Act. The deals to reduce water use are aimed at boosting the levels of Lake Mead, the nation’s largest reservoir near Las Vegas, which now stands at 34% of capacity.
The latest agreements “represent another critical step in our collective efforts to address the water management challenges the Colorado River Basin faces due to drought and climate change,” said federal Reclamation Commissioner Camille Calimlim Touton. “Addressing the drought crisis requires an all-hands-on-deck approach, and close collaboration.”

Scientists have found that roughly half the decline in the river’s flow this century has been caused by rising temperatures, and that for each additional 1.8 degrees of warming, the river’s average flow is likely to decrease about 9%…Interior Department officials said the newly signed agreements secure conservation pledges of up to 643,000 acre-feet of water through 2025. The agreements, which were announced in Las Vegas, include $295 million in federal funds for conservation, water efficiency and protection of environmental resources. An acre-foot of water is enough to supply about three average homes for a year. The Coachella Valley Water District has agreed to save up to 105,000 acre-feet of water through 2025, roughly 10% of its supply from the river. The district’s proposal was approved earlier this year, and involves curtailing the use of Colorado River water for replenishing groundwater. In exchange, the federal government is paying $400 per acre-foot of water…

In another agreement, the Quechan Tribe of the Fort Yuma Indian Reservation agreed to save up to 39,000 acre-feet of water in the next two years…Leaders of California’s Imperial Irrigation District, which delivers the single largest share of Colorado River water to farmland in the Imperial Valley, this month approved another agreement to conserve up to 100,000 acre-feet of water…That deal secured reductions in water use through an existing agricultural conservation program in the Imperial Valley and negotiations among several agencies. About half of the water had previously been earmarked to be sent to the San Diego County Water Authority under a water transfer agreement, but will instead remain in Lake Mead. The conserved water is enough to raise the reservoir’s level 1.5 feet…

Jack Schmidt, a professor who leads Utah State University’s Center for Colorado River Studies, recently analyzed reservoir levels and said in a blog post that “the rate of loss this year is much lower” than in all but one of the previous 10 years, “suggesting that current policies of reducing consumptive use may be working.”

He noted that while this year’s ample snowpack in the Rocky Mountains brought an increase in reservoir levels, a portion of those gains have been used. He said the amount stored in the river’s reservoirs is now the same as it was in May 2021.
“New plot using the nClimGrid data, which is a better source than PRISM for long-term trends. Of course, the combined reservoir contents increase from last year, but the increase is less than 2011 and looks puny compared to the ‘hole’ in the reservoirs. The blue Loess lines subtly change. Last year those lines ended pointing downwards. This year they end flat-ish. 2023 temps were still above the 20th century average, although close. Another interesting aspect is that the 20C Mean and 21C Mean lines on the individual plots really don’t change much. Finally, the 2023 Natural Flows are almost exactly equal to 2019. (17.678 maf vs 17.672 maf). For all the hoopla about how this was record-setting year, the fact is that this year was significantly less than 2011 (20.159 maf) and no different than 2019” — Brad Udall

The deepening troubles of the Colorado River, a significant source of water for most of Colorado’s 5.9 million residents, has implications for the types of grasses we grow in our yards and in street medians.
Speaking in Las Vegas recently, former Arizona Gov. and former U.S. Interior Secretary Bruce Babbitt recalled warnings of worsening drought and imbalances between supplies and demand. “There’s going to be a day of reckoning,” Babbitt, 85, told Politico’s E&E News, referring to the warnings of scientists during past decades. “Here we are. The crisis has arrived.”
Colorado’s mounting efforts to limit new expanses of thirsty turf won’t solve the Colorado River problems. Colorado is just one of seven states in the basin. And even within Colorado, agriculture consumes roughly 90% of Colorado’s water and cities about 7%. Exterior use, such as for watering thirsty Kentucky bluegrass yards, consumes 40% to 60% of municipal water.
But if this water use is on the margins, it’s one that many water managers believe must be addressed. A bill that originated in the Water Resources and Agriculture Review Committee in October has the support of two of the state’s largest cities and has sponsors from both political parties from across Colorado.
This proposal would preclude the installation of nonfunctional turf as well as artificial turf in commercial, institutional or industrial properties or in transportation corridors, such as along streets or in road medians. Nonfunctional turf is defined as grasses that are predominantly ornamental — and that few will ever walk on unless to mow, yet still require heavy watering. Think, for example, of those giant carpets of green grass that commonly surround business parks such as the Denver Tech Center or Broomfield’s Inverness business park.
The bill, however, does not address residential water use.
Many urban landscapes in Colorado are planted in Kentucky bluegrass and other thirsty species that require close to double what the semiarid climate delivers. Native grasses such as blue gramma and even some imported species can survive with far less or even no supplemental water.
Continued population growth also adds pressure to city water utilities. The Colorado Water Plan projects growth of the state’s current population to at least 7.7 million by 2050, mostly along the Front Range.
Legislators have been advised by the state’s Colorado River Drought Task Force to bump funding to $5 million per year for turf removal. In 2022, they allocated $2 million, which has now been exhausted in grants to local jurisdictions.
Also informing Colorado’s path forward will be recommendations from another task force, appointed by Gov. Jared Polis last January, to investigate opportunities for an accelerated transformation in use of water in urban landscapes. The 21 committee members were drawn from the ranks of local governments, academia, environmental advocacy groups and developers.
At their eight meetings, committee members wrestled with what should be the proper mix of incentives and mandates and ultimately just how far the state should push into matters of local land use. One member suggested that banning new turf in road medians was a no-brainer. Another member urged flexibility for local jurisdictions to achieve state goals. “We’re going to be on this journey for a long time,” said Catherine Moravec of Colorado Springs Utilities. “Less controversy will help keep us together.”
In final meetings, now concluded, members agreed on the need to support state legislation. The Colorado Water Conservation Board, which oversaw the process, emphasizes that the task force’s report will have no direct connection to legislation. The task force’s pending report “may be used by decision-makers at state, local or even neighborhood scales,” said Jenna Battson, the agency’s outdoor water conservation coordinator. “It’s a resource.” The task force recommendations are expected to be released in late January after review – and perhaps tweaking – by Polis.

Changing the status quo
Water scarcity underlies all these discussions. Specific circumstances vary. Some jurisdictions, most notably those between Denver and Colorado Springs, depend upon receding underground aquifers for most of their water. They get very little or no Colorado River water.
Most other jurisdictions do rely upon the Colorado River. Ambiguity has long dogged the Colorado River Compact, the agreement reached by delegates from the seven basin states in 1922. What if runoff declined substantially? The river since 2000 has delivered an average 12.3 million acre-feet per year, far short of the 20 million acre-feet that delegates had assumed.
Must Colorado and the three other upper-basin states — New Mexico, Utah and Wyoming — leave more water to flow downstream if runoff declines even more? That would cause curtailment of diversions with water rights after 1922. A study commissioned by the Glenwood Springs-based Colorado River Water Conservation District found that 96% of Front Range water use could be subject to curtailment.
That includes diversions by Denver Water. “It is possible that Denver Water’s deliveries of Colorado River basin supplies could be curtailed for a period of time,” advised a statement from Denver Water issued in August 2022 when the utility was issuing new water bonds.
That statement was issued the same month that Denver Water and 30 other utilities from Colorado to California that rely upon Colorado River Basin water committed to removing urban turf, with a goal of 75 million square feet in the case of Denver Water. That’s an area roughly equivalent in size to 1,800 football fields. At the current rate, that will be achieved in 100 years, according to Denver Water.
Even so, that was a sharp reversal for Denver Water, a utility that delivers water to 1.5 million people in Denver and 17 other municipalities in the metro area. Even after severe drought 20 years before, Denver made no move to remove turf. If drought got bad enough, the agency reasoned, it could ask customers to stop watering their yards. The utility now plans a pilot program in 2024 in conjunction with Resource Central to cost-share lawn removal with customers.
Greg Fisher, Denver Water’s manager of demand planning and efficiency, told legislators in October that spending money to help remove turf makes no sense if thirsty nonnative turf species are simultaneously being planted elsewhere.
“Ultimately, success for us is changing the status quo, creating a new cultural landscape that will benefit Colorado’s environment and save water at the same time,” he said. Fisher cited the ancillary benefit of providing habitat for pollinators, which is not provided by imported grasses. Denver supports the bill.
The proposed state law up for consideration in the 2024 session would also preclude artificial turf in lieu of grass. The bill says artificial turf releases harmful chemicals into watersheds and exacerbates the heat island effect compounded by rising temperatures in coming decades.
Colorado is famously a local-control state. Its towns and cities, many of them operating under home-rule charters, jealously guard local prerogatives. They, not the state, decide the speed limits on their streets and don’t like the state telling them what to do, particularly in land use. Always, there is tension.
But in water, the state has already adopted efficiency requirements. Any toilet sold in Colorado must consume no more than 1.2 gallons per flush. Colorado law also requires the most efficient pop-up sprinklers.
Should state law also override local authority in deciding landscaping choices? If still a sensitive area, even cities normally inclined to tell legislators to butt out are now more inviting of state engagement or at least inclined to remain neutral.
“Aurora will typically be one of the communities that shows up and says don’t do anything at the state level that impedes our local control,” Marshall Brown, general manager of Aurora Water, told the legislative committee in October in support of the ban on planting new vegetation with high water needs. This proposal, he added, retains local control while providing strong guidance from the state.
Real estate developers in Aurora typically created lavish areas devoted to turf along streets, including this one, but a 2022 law dramatically reduced what is permitted in future developments.

When Aurora changed its mind
For many years, Aurora tried voluntary programs for turf removal, in order to stretch its water. It made no sense if others then planted large amounts of grass. “We didn’t have success until we mandated a ban on nonfunctional turf,” Brown said.
In September 2022, Aurora City Council adopted a wide-ranging ordinance that is among the most aggressive in Colorado. It bans Kentucky bluegrass and other thirsty cool-weather grass in front yards of new residential developments. New golf courses are allowed, but not with thirsty grasses. They must have grasses that use less water. New ornamental water features, such as fountains, are also banned.
Several decades ago, Aurora had gained a reputation for lacking greenery due to the mostly treeless landscape of newer subdivisions.
“I would ask those people to go east of Aurora and see what they see,” said Tim York, water conservation manager for Aurora. “They won’t see turf and they won’t see very many trees. Although we aren’t against trees. We definitely need trees. Just be sure to put them in the right places.”
Aurora, now with a population of 400,000, for many decades believed it needed well-watered turf in its urban landscapes. Even in the late 1980s, the city water department had just one employee devoted to conservation.
“In retrospect, installing landscapes for aesthetic purposes that require over 2 feet of water per year was probably not the right way to do it,” said York.
US Drought Monitor June 25, 2002.
The 2002 drought forced a new reckoning. That hot, dry, windy year revealed the inadequacy of Aurora’s portfolio of water rights and storage, both for that intense drought but also in regard to projected population growth. The city’s utility manager warned of dire reductions if snow didn’t arrive. It did the next spring, on St. Patrick’s Day of 2003, but the episode revealed the city’s vulnerabilities.
Both reuse and conservation became an active part of the municipal agenda. Since then, per-capita water use has declined by 36%. The population during that time has grown by 30%. The city offered rebates to residents willing to replace their thirsty turf.
In 2022, though, the city recognized the fallacy of creating a bigger problem that would have to be addressed later.
York, a landscape architect by training with experience in Las Vegas, contends that pleasant urban landscapes can be created with lesser volumes of water. It just takes more thoughtfulness about the function.
“That function should not be that ‘It looks pretty’ and that is all that it does,” York said. “A water-wise landscape, done correctly with species variation, can be far more attractive than the monotonous green carpet turf found in most places.”
Aurora Mayor Mike Coffman said homeowners resisted the ban at first, as did some members of the City Council, who saw it as going too far. They were convinced by Coffman that taking action now may prevent more dramatic actions in the future if the Colorado River situation deteriorates further. Aurora gets 25% of its water from multiple sources in the Colorado River basin.
There were also arguments that water-wise landscaping is ugly.
“I don’t think it’s ugly,” Coffman said in an interview. “What is ugly is when homeowners, because of the cost of water, give up on their yards. That’s ugly. But anyway, it’s the new reality we live in, and people have to get used to it.”
Native grasses use far less water than Kentucky bluegrass and other imported species but can look bedraggled, as was evident in September at this site near the Colorado State University Spur Campus in Denver.

Down the Colorado River
Nevada and California have adopted far more significant restrictions.
A century ago, when the Colorado River Compact was crafted, Las Vegas had a population of little more than 2,000. The compact allocated only 300,000 acre-feet to Nevada, compared with 4.4 million acre-feet for California.
By 1996, Las Vegas was becoming a metropolitan area, and lawns replicating those found in Midwestern towns were still being planted in an environment of soaring summer heat and only 4 inches of average precipitation. The Southern Nevada Water Authority began offering incentives for turf removal. That program has since then cost $285 million, according to a January 2023 report prepared for the Colorado Water Conservation Board.
In 2021, with the notion of an empty Lake Mead becoming an all-too-real possibility, Nevada banned all ornamental turf dependent upon Colorado River water. Ornamental in this case applies to grass used in street medians, entrances to developments and office parks — in general, places where people rarely set foot except to mow. This covers about 31% of all the grass in the Las Vegas area.
California also took a very aggressive step in 2023. The law, Assembly Bill 1572, prohibits using drinking water for purely decorative grass in medians and outside business and in common areas of homeowner association neighborhoods, the Los Angeles Times reported in September. The ban will take effect in phases between 2027 and 2031. It exempts sports fields, parks, cemeteries and residences.
Metropolitan Water, the agency that supplies wholesale water to most of Southern California, estimates that the bill will save 300,000 acre-feet. That’s equal to Nevada’s Colorado River allocation.
Sterling Ranch may be Colorado’s best example of judicious water use. The development of more than 3,000 houses lies in the southwest corner of metropolitan Denver. The developer set out to do better than 0.75 acre-feet annually per single-family residence, which is Douglas County’s requirement. It aimed for 0.4 acre-feet but has come in at 0.2 acre-feet. The developer expects an apartment complex will yield even less consumption, at 0.14 acre-feet per unit.
Andrea Cole, general manager of Dominion Water & Sanitation District, the water provider at Sterling Ranch, said “conservation” is not used in messaging “because it implies that it was yours to use and we are asking you to please use less.” At Sterling Ranch, she said, developers combined demand-management techniques — including higher rates for outdoor water use — with land-use planning to dial down water use.
Several Colorado jurisdictions have taken more-limited action in the past several years. In August, for example, Broomfield adopted a code limiting new turf grass to 30% of front and side yards of detached single-family homes and commercial properties. Turfgrass must primarily consist of low-water grasses. Both a city and a county, Broomfield has 77,000 people but with expectations of growing to 125,000 as land is developed.
In Edgewater, a municipality of moderately dense neighborhoods west of downtown Denver, redevelopment will be the primary target of regulations adopted in November. The regulations limit Kentucky and other cool-weather grasses to 25% of residential areas. It also has limitations in commercial and other areas similar to what is proposed in the proposed state law.
Paige Johnson, sustainability director for Edgewater, said the primary goals are saving water and creating and sustaining robust and diverse natural ecosystems.
In Castle Rock, areas surrounding a football field are planted with native grasses that use less water. Waterwise regulations typically exempt athletic fields, parks and other common and higher-use areas from prohibitions against imported grasses.

And in Castle Rock
Castle Rock gets virtually no water from the Colorado River except for a tiny bit of reused water. It was a late bloomer among cities of metro Denver with fewer than 4,000 residents in 1980. The limited water from Plum Creek combined with wells drilled into aquifers of the underling Denver Basin were just fine.
It now has 80,000 residents but plans for 142,000 in decades ahead. In anticipation of that much larger population, it has been offering rebates of $1.50 per square foot for replacement of water-thirsty grasses with native species that use less water. Those who replace grass with concrete or artificial turf can get only $1. Both exacerbate heat-island effects of high temperatures and create more runoff problems during rains.
Castle Rock calls these less-thirsty yards “ColoradoScapes.” Such areas must have 75% vegetation to qualify.
In October 2022, after several years of outreach, Castle Rock adopted regulations that lifted the bar several notches higher. No thirsty grasses can be planted in front yards. Backyards, where families tend to gather, can have a maximum of 500 square feet. Castle Rock also banned new ornamental turf — grass that no one actually walks on — in road medians and at entrances to housing projects.
Mark Marlowe, director of Castle Rock Water, emphasizes cost in justifying the restrictions. Building water-treatment plants and distribution to meet peak demand during the hot days of summer bears a large price tag. Getting additional water from more distant places is also expensive.
Castle Rock residents today use 118 gallons per capita on average daily. “If we can get our community below 100 gallons per capita a day, we can save upward of $70 million in long-term water rights and infrastructure,” Marlowe said.
Similar to other Colorado cities, 50% of Castle Rock’s water was devoted to outdoor landscaping. That has declined to 42%. Marlowe projects it will continue to drop as Castle Rock Water has set a goal of removing 30% of the current non-functional grass turf in the municipality and replacing it with Coloradoscape by approximately 2050.
Limiting water devoted to outdoor landscaping helps Castle Rock in another way. Water applied to outdoor landscapes mostly disappears into the atmosphere, while about 90% of water used indoors gets treated. In many places in Colorado, this treated water is released into streams and rivers to satisfy those with water rights downstream.
Because it draws the water from the aquifers, Colorado water law allows Castle Rock to reuse that water repeatedly, to “extinction.” Overall, the city hopes to achieve 75% renewable water by midcentury, reserving use of the Denver Basin aquifers to droughts.
Denver has a very different situation. A century ago, when Castle Rock was a small ranch town of fewer than 500 residents, Denver already had 256,000 people. Envisioning a far larger city, civic leaders had laid plans for Colorado’s first major transmountain diversion to take water from the Fraser River via the Moffat Tunnel.
Now, the city is landlocked, able to grow upward but not outward. Water use has leveled off. The city has a strong water portfolio but wants to help residents learn how to use less water for landscaping.
“You don’t have to have wall-to-wall grass to have an inviting city,” said Denver Water’s Fisher. He cautioned against pointing fingers at those with cool-weather turf. “I do think we’re trying to slowly change how people approach their landscapes and make that connection back to water,” he said.

In Colorado Springs, the state’s second-largest city, overall water demand has remained relatively flat since the mid-1980s. During that time, the city’s population has nearly doubled. Most of that 40% decline in per-capita water use has occurred since 2001. Other Front Range cities similarly report substantial declines of 35% to 40%.
Colorado Springs Utilities has championed the use of native grasses in urban landscaping but also paid careful attention to the efficiency of preinstalled irrigation systems as it plans for a population of 800,000 in coming decades. It’s now at 500,000.
The city also wants to help residents maintain their yards using water-wise techniques. Between 25% and 30% have stopped irrigating their yards. That neglect “has a significant, negative impact on our collective quality of life and economic vitality,” said Colorado Springs Utility in a statement. “Our work is to reach those customers as well.”
The changing climate also poses challenges. Julia Galluci, supervisor of water conservation for Colorado Springs, said the city expects to have water resources available for outdoor watering about one day a week by 2050. “We are trying to implement the kinds of landscapes that can survive in that kind of climate and environment,” she said.
Colorado Springs has been moving slowly, only this year moving into its messaging of the more general population. “It’s not a quick fix,” said Galluci.
Of course, if the Colorado River situation deteriorates rapidly, city and state policies may accelerate. After last winter’s strong snowpack, the big reservoirs— Mead and Powell — rebounded slightly after dropping to perilously low levels. In April 2022, railroad tracks on a ledge of the canyon wall that had been abandoned upon completion of the Glen Canyon Dam re-emerged after being underwater since soon after the dam was completed in 1966. Those artifacts are underwater again, but no one knows for how long.
As for new golf courses, they may look different in the future. Aurora’s recent commitment to restrictions was triggered by a golf course approved long before. The golf course has been granted authority to move ahead after agreeing to use a grass variety that will cause it to use 250 acre-feet annually instead of the 400 acre-feet that would be needed by more conventional grass.
Developers of the golf course will tap an aquifer with a projected 50-year supply. When that aquifer goes dry, they will not seek to use city water, Other golf course developers may also want to study new hybrid species of grass. A new type of Bermuda grass, for example, uses 50% to 75% less water.
Colorado has two golf courses that use no more water than comes from the sky. One is a nine-hole municipal course at Springfield, in southeast Colorado. The other lies 100 miles east of Aurora, near Hugo. The Hugo Golf Club falls under the heading of “pasture golf.” It has 300 trees that get watered, but the fairways where bison once grazed now consist of native buffalo grass, cactus and sagebrush. For greens, it has sand. Naturally, it has no water hazards.

Programs that would pay water users to conserve and send that water downstream for the benefit of the Colorado River system remain too controversial for Colorado water managers to agree on.
A statewide task force has failed to make recommendations to lawmakers about the primary issue they were supposed to tackle: how to address drought in the Colorado River basin and respond to a downstream call through water conservation programs.
Senate Bill 295 created the 17-member Colorado River Drought Task Force this year, with representatives from Western Slope water users, Front Range water providers, local governments, the state Department of Natural Resources, environmental groups and tribal leaders. The group met 10 times between July and December at locations across the state and remotely.
According to SB 295, the purpose of the task force was to provide recommendations for state legislation “to develop programs that address drought in the Colorado River basin and interstate commitments related to the Colorado River and its tributaries through the implementation of demand reduction projects and the voluntary and compensated conservation of the waters of the Colorado River and its tributaries.”
But a draft recommendation about what a conservation program should look like lost on a 9-7 vote, meaning task force members did not advance it as a recommendation to legislators. A narrative about the issue was still included in the report.
“I was personally disappointed that some of the larger topics that are out there in the water world or brought up at the task force did not get support from the task force,” said state Sen. Dylan Roberts, a Democrat who represents District 8 and was a sponsor of SB 295. “They either didn’t have time or shied away from those conversations about longer-term solutions.”
The losing recommendation contained many of the state’s same long-discussed themes surrounding demand management: Any potential program should be temporary, voluntary and compensated, should avoid disproportionate impacts to any one region, and must not injure other nonparticipating water rights holders; and Western Slope conservation districts should be involved with projects within their boundaries.
Task force members could not agree on whether the timing was right for such a program, with some saying it’s “premature.” The “no” votes came from those representing Front Range water providers, the Department of Natural Resources, the Department of Agriculture, the Southwestern Water Conservation District and Colorado’s two tribes, the Ute Mountain Ute Tribe and Southern Ute Indian Tribe.
“I think there is a lot of institutional pressure that keeps us tethered to the status quo in water policy in Colorado,” said Roberts, who represents Clear Creek, Eagle, Garfield, Gilpin, Grand, Jackson, Moffat, Rio Blanco, Routt and Summit counties. “We owe it to Coloradans and the people in the West to grapple with the reality of what faces us in the decades ahead. … There’s no time like the present to prepare for a bad situation.”
The lack of recommendations about conservation programs highlights the complicated nature of water in Colorado and the difficulty of achieving consensus among competing interests. A 2021 work group that had been created to tackle speculation also failed to make recommendations to lawmakers.

Conservation controversy continues
Demand management, water banking, system conservation, a strategic water reserve — the names and details are different, but the basic concept is the same: paying water users to use less on a temporary and voluntary basis. They have been controversial in Colorado, with skeptics saying these types of programs could strip rural agricultural communities of their water.
The Colorado Water Conservation Board undertook its own demand management feasibility investigation in 2019 with eight work groups devoted to exploring different aspects of a potential program. The CWCB shelved the investigation last year without implementing a program.
Some have argued that implementing a state conservation program now would weaken or constrain Colorado’s negotiating position among the six other Colorado River basin states as they hammer out new reservoir operating guidelines. The concern is that implementing a program now would remove the focus from where some say it belongs — that the crisis is driven by overuse in the lower basin. Some task force members said they simply didn’t have enough time to thoroughly discuss conserved consumptive use (CCU) programs.
“Unfortunately, the task force spent very little time discussing this recommendation,” Southwestern Water Conservation District General Manager Steve Wolff wrote in the report. “If we had, we may have been able to develop language that we all could have agreed to and moved a recommendation forward. As written, there are aspects that could not be supported by Southwestern.”
Alexandra Davis, Aurora Water’s deputy director of water resources, served on the task force and voted “no” on the recommendation on conservation programs.
“It’s been contentious,” Davis said. “The CWCB has had a difficult time coming to some sort of idea of what kind of program would benefit the state as a whole and to create sideboards for something that we haven’t been able to agree on yet just seemed premature.”
The Glenwood Springs-based Colorado River Water Conservation District, which recognizes that any CCU program is likely to heavily involve water users within its 15-county Western Slope area, has taken the lead on demand management and system conservation discussions and has commissioned its own studies on the topic in recent years. River District General Manager Andy Mueller wrote the minority report on the task force’s failed recommendation.
“Unfortunately, the task force was unable to provide clear guidance to the members of the General Assembly with respect to how our state should be prepared to move forward should the pressure to participate in an interstate conserved consumptive use program increase in the future,” Mueller wrote. “We respectfully disagree that the CCU proposal is premature, and that this conversation should wait until a specific program is implemented.”
Although the River District does not necessarily endorse a CCU program, officials have repeatedly said they should be prepared with guidelines that protect water users if the state decides to go forward with one and that the River District should be involved to ensure a measure of local control.
“If there are programs that are designed incorrectly, …you will destroy the future of our communities,” Mueller said at the Dec. 7 task force meeting in Denver. “We have seen an interstate water conservation program roll out without any approval by our state legislature or our government and we could see another one come out. … The West Slope will be the target of that produced water.”
Mueller was referring to the Upper Colorado River Commission’s System Conservation Program, which pays water users in the upper basin states — Colorado, New Mexico, Wyoming, Utah — to conserve. The program was rolled out in 2022 without evaluation or approval by the River District.

12 recommendations
The task force still came up with eight recommendations to legislators, most of which are expansions of or increased funding for existing programs: Continue funding of a technical assistance grant program; increase funding for aging water-related infrastructure; prioritize forest health and wildfire-ready watersheds; expand a temporary loan program to include storage rights; expand agricultural water rights protections beyond divisions 1 and 2 (the South Platte and Arkansas river basins); continue state funding of measurement tools; remove invasive species; and increase funding for municipal turf removal.
A sub-task force on tribal matters made four recommendations: fund a study of a potential pilot program to compensate tribes to not develop their water; have state officials write a letter requesting the U.S. Congress fully fund the Indian Irrigation Fund; waive a requirement for matching funds for state grant programs; and provide cultural protection of instream flows.
Task force Chair Kathy Chandler-Henry — a nonvoting member of the group, the president of the River District board and an Eagle County commissioner — said the time constraints were challenging. Coming up with recommendations in just five months for a field that normally moves at a snail’s pace was hard.
“I think the work that was done in that concentrated period of time is going to bear fruit in ways we don’t know about yet,” she said. “I think that, in itself, is the real value of the task force.”

Another interesting aspect is that the 20C Mean and 21C Mean lines on the individual plots really don’t change much. Finally, the 2023 Natural Flows are almost exactly equal to 2019. (17.678 maf vs 17.672 maf).

The final recommendations from a statewide task force charged with finding water-saving solutions for the drying Colorado River focus largely on expanding and tweaking existing programs…Delivered after four months of hours-long meetings, all but one of the eight recommendations would expand or change current programs, including initiatives aimed at continuing the measurement of snowpack, improving water infrastructure and boosting a program to replace thirsty grasses with native plants…
State lawmakers formed the 17-member Colorado River Drought Task Force in May, charging it with drafting recommendations for legislation to address drought and overuse in the Colorado River Basin. Members of the task force spanned a wide range of water interests, including representatives from environmental nonprofits, utility companies, the agricultural sector, state and local government, the Ute Mountain Ute and Southern Ute tribes…
The task force’s eight recommendations to the legislature are to:
Expand a program that helps local entities apply for federal grant money for water projects
Direct more money to state programs that pay for improving and repairing aging water infrastructure, like ditches and headgates. The improvements will help water systems be more efficient and lose less water to leakage or transit.
Expand a program that allows some water rights holders to loan their water to the Colorado Water Conservation Board to preserve and improve the environment
Expand statewide a program that allows agricultural water rights holders to lease, loan or trade part of their allotment
Continue funding improvements to technology to measure stream flows and snowpack statewide
Pay for a statewide assessment of changes in riparian plant communities and fund a statewide program to control and remove invasive plant species that hurt waterways, such as tamarisk and Russian olives
Increase funding from $2 million to $5 million for an already established program that incentivizes the replacement of water-sucking turf with native grasses and plants
[…]
The task force’s recommendations might do some good but they only “scratch the surface of the problem,” Mark Squillace, a water law professor at the University of Colorado, wrote in an email. The inherent problem is that people who use Colorado River water are using more than the river produces in an average year, he said. Solutions must involve permanent reduction of consumption, he said, such as paying farmers to switch to plants that consume less water or limiting water rights so that farmers have a slightly shorter growing season. More broadly, the seven Colorado River states should consider creating a new compact with a promise to modernize their water laws, he said.
Western states are on a collision course as they scramble to cut a deal to dramatically shrink their use of the drought-stricken Colorado River ahead of a March deadline from the Biden administration. The brawl unfolding among the states that rely on the West’s most important waterway will shape the economies for cities from Denver to Los Angeles as well as some of the nation’s most productive agricultural areas. And it poses a political dilemma for President Joe Biden, who could see the problem complicate his political calculations in a trio of swing states — Arizona, Nevada and Colorado — along with California, home to many of his most deep-pocketed donors…The tensions were apparent this week as negotiators here exchanged heated words from the podium in front of the hundreds of technocrats, tribes, and farmers who manage the river’s water and were gathered at a Las Vegas casino for their annual conference.

“Ideally this is something that all seven basin states can come up with together. But I want to be real clear that we can’t accept something that continues to drain the system, that puts 40 million people at risk,” said Becky Mitchell, the fiery lead negotiator for the state of Colorado who has objected to her state accepting reductions to its water use…
Much of the tension now centers on whether the Upper Basin states should share in the cuts needed to bring water use in line with the shrinking supply. Arizona, Nevada and California’s negotiators say they are close to a long-term deal that would stanch their use to bring it in line with the water that the river has delivered historically — a gap known as the “structural deficit.” But that just deals with the century-old over-allocation problem. Those reductions will almost certainly fall short of what will be needed to deal with the pain Mother Nature is inflicting, and those Lower Basin states argue that burden should be shared by Wyoming, Colorado, Utah and New Mexico, as well as Mexico, which gets a slice of the river, too…
The structural deficit refers to the consumption by Lower Basin states of more water than enters Lake Mead each year. The deficit, which includes losses from evaporation, is estimated at 1.2 million acre-feet a year. (Image: Central Arizona Project circa 2019)
“The structural deficit — we’re going to own that,” said Tom Buschatzke, Arizona’s lead negotiator. But what it takes after that to stabilize the river “will be a shared responsibility. A shared responsibility for everybody in the basin — all seven states and Mexico.”

Nearly $295 million from President Biden’s Investing in America agenda will conserve up to 643,000 acre-feet of water through 2025
December 13, 2023
The Biden-Harris administration today announced agreements with several California water agencies to conserve up to 643,000 acre-feet of water in Lake Mead through 2025. The agreements include approximately $295 million in new investments from President Biden’s Investing in America agenda, a key pillar of Bidenomics, which will fund projects for water conservation, water efficiency, and protection of critical environmental resources in the Colorado River System.
Bureau of Reclamation Commissioner Camille Calimlim Touton joined federal, Tribal and state leaders in Nevada today to announce the execution of new water conservation agreements, including an agreement with the Coachella Valley Water District to save up to 105,000 acre-feet of water through 2025 and an agreement with the Quechan Indian Tribe to save up to 39,000 acre-feet through 2025. The event also commemorated a recently signed agreement with the Imperial Irrigation District to conserve approximately 100,000 acre-feet of water in 2023. The leaders also announced that additional system conservation agreements with the Palo Verde Irrigation District, Bard Water District – in cooperation with the Metropolitan Water District of Southern California – and a second agreement with the Coachella Valley Water District are expected to be finalized in the coming weeks.
The investments are part of the Biden-Harris administration’s all-of-government approach to improve and protect the stability and sustainability of the Colorado River System now and into the future. They are administered through the Lower Colorado River Basin System Conservation and Efficiency Program and funded by the Inflation Reduction Act, the largest climate investment in history.
“Thanks to President Biden’s Investing in America agenda, the Interior Department is working collaboratively with states, Tribes, farmers, and water districts across the West to help address, improve and protect the long-term stability of the Colorado River System,” said Secretary Deb Haaland. “The Biden-Harris administration is using every tool and resource at our disposal to continue our sustained, collaborative progress in increasing water conservation across the West.”
“These agreements represent another critical step in our collective efforts to address the water management challenges the Colorado River Basin faces due to drought and climate change,” said Reclamation Commissioner Camille Calimlim Touton. “Addressing the drought crisis requires an all-hands-on-deck approach, and close collaboration among federal, state, Tribal and local communities. When we work together, we can find solutions to meet the challenges of these unprecedented drought conditions.”
President Biden’s Investing in America agenda is integral to these efforts to increase near-term water conservation, build long term system efficiency, and prevent the Colorado River System’s reservoirs from falling to critically low elevations that would threaten water deliveries and power production.
Conservation efforts made possible by this funding have already benefited the system this year. The California conservation agreements announced today join 18 water conservation implementation agreements with critical partners in Arizona, including state agencies, Tribes, and agricultural and municipal water users, which commits water entities to conserve up to 348,680-acre feet of water in Lake Mead in 2023, and up to 984,429-acre feet through 2026. The agreements are part of the 3 million acre-feet of system conservation commitments made by the Lower Basin states, 2.3 million acre-feet of which will be compensated through funding from the Inflation Reduction Act.
As a result of the commitment to record volumes of conservation in the Basin, as well as recent hydrology, Interior Department announced in October 2023 that the chance of falling below critical elevations has been reduced to eight percent at Lake Powell and four percent at Lake Mead through 2026. Lake Mead is currently about 40 feet higher than it was projected to be at this time last year.
To date, the Department has announced the following investments for Colorado River Basin states through the Bipartisan Infrastructure Law and Inflation Reduction Act, which will yield hundreds of thousands of acre-feet of water savings each year once these projects are complete:
$281 million for 21 water recycling projects that are expected to increase annual water capacity by 127,000 acre-feet annually;
Up to $233 million in water conservation funding for the Gila River Indian Community, including $83 million for a water pipeline project;
$71 million for 32 drought resiliency projects to expand access to water through groundwater storage, rainwater harvesting, aquifer recharge and water treatment;
$50 million over the next five years to improve key water infrastructure and enhance drought-related data collection across the Upper Colorado River Basin; and

The results of a recent economic study of Grand County irrigators show that certain water conservation programs may be worth it for irrigators who grow hay but not for those who grow cows.
In 2020, a group of nine flood irrigators in the Kremmling area, scientists and conservation groups began a multiyear research project to find out what happens when irrigation water is withheld from high-elevation fields for a full season and a half-season. The project, officially called “Evaluating Conserved Consumptive Use in the Upper Colorado,” is ongoing through 2023, but preliminary results from 2020-22 show that the effects of taking water off a field linger beyond one season and that these types of programs may not make financial sense for irrigators who raise livestock.
In 2020, control fields were irrigated normally; some fields received no irrigation water and some received irrigation water only through June 15. Normal irrigation practices were resumed in 2021, 2022 and 2023. But the fields with no or less water in 2020 did not fully bounce back and produce the same crop yield as the control fields in subsequent years. The amount of water used by the plants, known as consumptive use, as well as the amount of forage crop production, lagged behind the control fields even two years after resuming normal irrigation, something maybe partly due to the extreme drought in the summers of 2020 and 2021.
Perry Cabot, a researcher with Colorado State University, and Hannah Holm, associate director for policy with environmental group American Rivers, worked on the project and presented their findings to the Colorado Basin Roundtable last month.
“2020 was such an awful, horrible drought year, especially late in the season,” Holm said. “We are wondering if the fact that there was basically no precipitation falling from the sky, and that summer of 2021 [was also dry], might have knocked back the treatment fields that much harder. … We do see substantial recovery when returned to full irrigation, but it’s not uniform across the fields and it seems to not be 100% a couple of years later.”
Where water was removed for half of the irrigation season, irrigators received $281 per acre, and those with full irrigation withdrawal received $621 per acre in 2020.
The study was funded by the Colorado Water Conservation Board, with support from the Colorado Basin Roundtable, The Nature Conservancy, Trout Unlimited and American Rivers.
The 2020 Economics and Enterprise Budgeting Report, released in August as part of the preliminary project report, found that these amounts need to be increased for irrigators who also raise livestock to make participation in the program worth it for them. The report, which is based on interviews, financial data and budgets from six of the participating irrigators, said agricultural producers who relied on their hayfields to feed cattle experience a net loss of profit, despite the payments.
Producers with livestock would have needed an average payment of at least $971 per acre to fully compensate them for the additional costs of not irrigating their fields. This was mostly due to the high cost of having to buy hay in a drought year to replace the hay they didn’t grow.
Those just growing hay saw an average of a $197 increase in income per acre on the full-season treatment fields; those growing hay saw an average $46 loss per acre on the half-season treatment fields. Those who also had a herd of cows to manage in addition to growing hay lost an average of $350 of income per acre on the treatment fields.
Paul Bruchez, a Kremmling rancher and CWCB member, is one of the project’s leaders.
“We were part of creating a deficit in our local hay market,” he said. “That was compounded by what was a natural drought. And then the end result was that hay was off-the-charts expensive.”
Many ranchers continue irrigating late into the season after their last cutting of hay so that they can grow back a little bit of grass, alfalfa or other forage crop on which their cattle can graze for several weeks in the fall before they start feeding them hay. Ranchers who participated in the project also lost this bit of fall grazing because they didn’t irrigate.
“They had a loss of production initially for the harvesting of the hay to feed them through the winter, but then they also lost fall grazing,” said Jenny Beiermann, an agriculture and business management specialist with Colorado State University, who co-authored the economics study. “They incurred a lot of additional expenses compared to those who were just harvesting hay, and that’s why they needed a higher rate of payment for their fields.”
These cows live on the Fetcher ranch in Clark, north of Steamboat Springs. The results of a recent economics study found that certain types of water conservation programs may be worth it for irrigators who grow hay, but not for those who raise livestock.

System conservation
These findings could have basinwide implications for the Upper Colorado River Commission’s System Conservation Program, which in September water managers voted to continue in 2024. The federally funded program pays irrigators to forgo watering their fields for a season with the goal of protecting critical elevations in the nation’s two largest reservoirs, Lake Powell and Lake Mead. The 2024 program will have a narrower scope that explores demand-management concepts and supports innovation and local drought resiliency on a longer-term basis.
For the 2023 System Conservation Program, water managers set the opening payment to producers at $150 per acre-foot conserved, a number that some producers told Aspen Journalism was insultingly low. Producers could then negotiate up from there. SCP project participants in Colorado were paid an average of about $394 for every acre-foot conserved. The average price per acre-foot across the four upper basin states — Colorado, Utah, Wyoming and New Mexico — was $422.
For 2024, the program will offer Colorado irrigators a fixed price of $509 per acre-foot conserved.
UCRC Executive Director Chuck Cullom said the agency used projected commodity prices and crop budgets from CSU to arrive at the amount of compensation offered to producers for 2024 and did not take into account whether an irrigator had a cow/calf operation.
Another thing the project is studying is how birds use irrigated agricultural lands. But the results through 2022 of an avian monitoring project by Audubon Rockies were inconclusive. Researchers expected that when irrigation was resumed in the years after 2020, there would be more water-associated birds. The number of bird species counted did increase in 2021 — the first year irrigation water returned — but not in 2022.
“In some regard, the results from 2022 were diminished from those in 2020 (treatment year), which further opposed our expectations,” the report reads. “Birds are highly diverse, mobile creatures that use a wide array of habitats for many different seasonal purposes, often making it challenging to interpret the outcomes of avian monitoring efforts.”
The thing to keep in mind about the economics study, Beiermann said, is that it was small and that conditions in high-elevation Grand County can be particularly brutal, with long winters. Drought and water availability can vary widely across the upper Colorado River basin and from year to year. Still, a key takeaway is that these types of water conservation programs may be better suited for irrigators who grow only hay.
“Agriculture is a really risky business and being profitable is really tough,” she said. “There are too many variables (for livestock producers). Generally speaking, they are going to have a lot higher costs.”
Romancing the River – I am aware, as you are probably aware, that when I title these posts ‘Romancing the River,’ I am talking about the life work of the kinds of people who do not usually think of themselves as ‘romantics,’ or of their water-related work as ‘romancing the river.’
Engineers, lawyers, politicians, managers, career bureaucrats, scientists – they all see themselves as rational beings just doing what must be done to rationalize a random force of nature, to put the river to beneficial use feeding, watering, powering and even entertaining us. That’s‘romancing the river’? It’s almost an insult to call these serious public servantsromantics, a term which resonates with most people today as not really very serious, just ‘love stories’ – so unserious it’s hardly worth them answering me when I call them romantics (which they don’t); easier for them to just dismiss me as some kind of nut (which they might).
“New plot using the nClimGrid data, which is a better source than PRISM for long-term trends. Of course, the combined reservoir contents increase from last year, but the increase is less than 2011 and looks puny compared to the ‘hole’ in the reservoirs. The blue Loess lines subtly change. Last year those lines ended pointing downwards. This year they end flat-ish. 2023 temps were still above the 20th century average, although close. Another interesting aspect is that the 20C Mean and 21C Mean lines on the individual plots really don’t change much. Finally, the 2023 Natural Flows are almost exactly equal to 2019. (17.678 maf vs 17.672 maf). For all the hoopla about how this was record-setting year, the fact is that this year was significantly less than 2011 (20.159 maf) and no different than 2019” — Brad Udall
So let me try again to explain myself – and why I believe it is neither criticism nor praise to suggest that the army of engineers, lawyers, politicians, career bureaucrats, scientists who have remade the Colorado River have been ‘romancing the river.’ It is a perspective to get up on the table and think about, as we find ourselves at a kind of still point: trying to figure out how to go forward from a century of river development that has ended uncomfortably close to a systemic collapse. It is hard to see 2022-23 as anything other than that, and we’ve only been temporarily reprieved with a wet winter and Biden’s infrastructure bucks giving us time to figure out how to do better for the future.

My thinking on this started with the book, mentioned here in posts more than a year ago, by Frederick Dellenbaugh, who came right out and said it in his title: The Romance of the Colorado River. Dellenbaugh, remember, first encountered the Colorado River as seventeen-year-old, in a boat with Major John Wesley Powell, on the scientist’s second trip down the canyons of the river in 1871-2.
Major Powell was better prepared and more experienced on that second trip, and actually able to accomplish some scientific work rather than just trying to survive. But for young Dellenbaugh, it was a big eye-opening experience – life-shaping, really: he spent the rest of his life exploring other unknown parts of the still-wild West, and collecting the stories of other adventurers.
He published The Romance of the Colorado River in 1902, thirty years after his formative trip with Powell – and the year the federal Reclamation Service was created as a branch of the U.S. Geological Survey, within 20 years the organization orchestrating the river’s development.
Dellenbaugh pulled no punches in describing his sense of the river and the challenge it represented. After noting in his introduction that ‘in every country, the great rivers have presented attractive pathways for interior exploration—gateways for settlement,’ serving as ‘friends and allies’ – he launches into his impression of the Colorado River:
THE GRAND CANON,
LOOKING EAST FROM TO-RO-WEAP
From “Exploration of the Colorado River of the West and Its Tributaries” By J. W . Powell, 1875
‘By contrast, it is all the more remarkable to meet with one great river which is none of these helpful things, but which, on the contrary, is a veritable dragon, loud in its dangerous lair, defiant, fierce, opposing utility everywhere, refusing absolutely to be bridled by Commerce, perpetuating a wilderness, prohibiting mankind’s encroachments, and in its immediate tide presenting a formidable host of snarling waters whose angry roar, reverberating wildly league after league between giant rock-walls carved through the bowels of the earth, heralds the impossibility of human conquest and smothers hope.’
There’s Dellenbaugh’s ‘romance of the river’ – an adventure story of rising to meet a challenge, a call to action to overcome obstacles. A veritable dragon refusing to be bridled? Impossible? Prohibiting encroachment? Smothering hope? We would see about that!
And while it’s not a conventional love story, passion is involved, the kind that can turn on a dime between love and hate. We loved the presence of water in a dry land – but the water was fickle at best, destructive at worst. Every farmer trying to irrigate from its two-month flood that turned into a trickle when they most needed it knew that love-hate relationship; it became the century-long (thus far) story of a strong and ornery people testing some new-found technological strength through picking a fight with a strong and ornery protagonist: we would teach the river to stand in and push rather than cutting and running.
Dellenbaugh was not the only one turning it into a romantic adventure. When the Colorado River Compact had been hammered out in 1922, the Commission Chair and Commerce Secretary Herbert Hoover announced that ‘the foundation has been laid for a great American conquest.’ In a 1946 report cataloging all the possible developments for the Colorado river’s upper tributaries, the Bureau of Reclamation carried forward Dellenbaugh’s assessment in its subtitle: ‘A Natural Menace Becomes a National Resource.’ These were the official public perceptions guiding our relationship with the Colorado River.
For three-quarters of the century that followed publication of Dellenbaugh’s Romance, America embraced that romantic challenge, answering the call to conquest, taking on those obstacles, not just individually but as a national project, a big last step in the ‘Winning of the West.’ And fueled by the power unleashed by buried carbon fuels, we were ready for the fight; it was the Early Anthropocene, and it was our planet to reform.

Remarkable things were done to the river as a result. The ‘veritable dragon’ has been broken and bridled for commerce and ‘utility everywhere.’ Its breaking and taming for commerce and utility is so massive that it practically requires the satellite view to take it in – the vast new ‘desert delta’ where the waters of the former desert river are spread from Phoenix and Tucson on the east, around through large squared-off green agricultural developments spotted with towns and cities, through the Imperial and Coachella valleys to Los Angeles and San Diego on the west…. And that’s just downriver; upriver are the tunnels through the mountains, taking water from the headwaters into the Platte, Arkansas, Rio Grande Basins, and into the Great Basin itself – how long will it be before Anthropocene math calculates that there might be enough water left in the Green River to move some through the Central Utah Project workings to help recharge the Not-So-Great Salt Lake?
For me, the ‘utility’ that cements the idea that this has been a big romantic adventure is the way we have kept significant reaches of river ‘wild’ enough for industries replicating Dellenbaugh’s formative adventure. Slipping onto the tongue and into the thrashing maw of Lava Falls, it is still easy to imagine a ‘veritable dragon,’ and millions of people from all over the planet come out of the Grand Canyon having relived Dellenbaugh’s romantic adventure.
But at the same time…. We also have to face some things that are less to be celebrated. Which brings me to Mary Austin again, another writer of the southwestern deserts mentioned here before, and her skeptical observation on Arizona’s ‘fabled Hassayampa,’ an intermittent tributary of the Gila River west of Phoenix, ‘of whose waters, if any drink, they can no more see fact as naked fact, but all radiant with the color of romance.’ Phoenicians have been drinking from the Hassayampa for a century now, wrapped up in the romance of the happy golden years in green and sunny places – and the underlying standard American romance of great wealth to be harvested fulfilling such romantic dreams.
But the ‘naked facts’ don’t go away just because we don’t want to see them, and there’s a kind of cosmic irony in the fact that, right where the Hassayampa flows into the Gila (when it’s actually flowing), two big developments, Buckeye and Teravalis, have been shut down at least temporarily on further development because they can’t present evidence of a hundred-year water supply. (See this post last spring.)
The mayor of Buckeye, Eric Orsborn, who also owns a construction business, is not discouraged by this. ‘My view is that we’re still full steam ahead,’ he said in an article in The Guardian. ‘We don’t have to have all that water solved today…. What we need to figure out is what’s that next crazy idea out there’ for bringing in a new water supply. An idea under consideration currently is a desalinization plant down in Mexico on the Gulf of California, and a pipeline to bring the desalted water a couple hundred miles uphill to central Arizona. Crazy, and very expensive – but we’ve been saying in Colorado for decades now, as though it were a mother truth, ‘Water flows uphill toward money.’
But other naked facts have also been dimming the radiance of the Anthropocene conquest of the Colorado River. Water users have been coping for half a century with water quality issues stemming from using water over and over to irrigate alkaline soils. We also didn’t really know – and some states continue to refuse to acknowledge – how much water would be lost to evaporation from big reservoirs, hundreds of miles of open and unlined canals, and flood or furrow irrigation on subtropical desert lands. About a sixth of the river is vaporized annually.
The basic explanation for why CO2 and other greenhouse gases warm the planet is so simple and has been known science for more than a century. Our atmosphere is transparent to visible light — the rainbow of colors from red to violet that make up natural sunlight. When the sun shines, its light passes right through the atmosphere to warm the Earth.
The warm Earth then radiates some of its energy back upward in the form of infrared radiation — the “color” of light that lies just beyond red that our eyes can’t see (unless we’re wearing infrared-sensitive night-vision goggles). If all of that infrared radiation escaped back into space, the Earth would be frozen solid. However, naturally occurring greenhouse gas molecules, including not just CO2 but also methane and water vapor, intercept some of it — re-emitting the infrared radiation in all directions, including back to Earth. That keeps us warm.
When we add extra greenhouse gases to the atmosphere, though, we increase the atmosphere’s heat-trapping capacity. Less heat escapes to space, more returns to Earth, and the planet warms.
But the biggest, most unforeseen collateral fact diminishing our conquest of the river is the turbulence we’ve wrought in the climate – increasingly an unignorable ‘naked fact.’ All the heavy technology and concrete we’ve invested in controlling the river, as well as all the technology of daily living that depends on burning carbon fuels, not to mention the methane from livestock and human waste – all our gaseous carbon emissions have increased the heat-holding capacity of the atmosphere, which in turn increases the heat energy driving our weather systems. We’ve seen this just this past year: how that changing balance can result in ‘atmospheric rivers’ of vapor forming over the ocean and dumping huge snowpacks when it condenses over the mountains – but then being back on the ‘abnormally dry’ edge of drought within a few months of the day-to-day water-sucking aridification that is the shape of the future.
So we Anthropocenes have conquered the river, bridled the dragon – but as we saw in the previous post here, we lost a full third of the river as the collateral consequences, unforeseen or just ignored, of the conquest. And all responsible prognosticators project that we will lose maybe another sixth of the river by mid-century to our drying out of the planet.
There are a number of ways to look at this. One would be to say, like Eric Orsborn, okay, there have been setbacks, but we can’t stop now; we need to finish the job. And he is far from the only Phoenician saying that. The state has a governor now and a Water Resources Department who know when it’s time to call a halt, but the state also has a Water Infrastructure Finance Authority charged with creating new water supplies for the state. The Mexican desal plant and megamile pipeline is just one idea in WIFA’s portfolio of possibilities; the old unkillable idea of bringing water over from the Missouri or Mississippi Rivers is still on their list.
‘Those are big, audacious ideas, but I don’t think any are off the table,’ WIFA director Chuck Podolak told The Guardian. ‘We’re going to seek the wild ideas and fund the good ones.’ The romance of conquest throbs on; Hoover Dam was a wild idea a century ago, so why stop now?
A water policy analyst at Arizona State University, Kathryn Sorensen, toldThe Guardian that ‘the degree of [Buckeye’s] success will depend on the degree to which people are willing to pay for those more expensive solutions. But it’s absolutely feasible. We pave over rivers, we build sea walls, we drain swamps, we destroy wetlands, we import water supplies where they never would have otherwise gone. Humans always do outlandish things, it’s what we do.”
There is diminishing enthusiasm today, however, for the romance of conquest; dwellers in the megacities are increasingly reluctant to embrace higher water bills in order to finance more growth, more people, more traffic, longer lines everywhere – San Diego is an example today. The same is true for urban/suburban water conservation; there is a romantic appeal to helping one’s city by conserving in an emergency situation, a drought period or a maintenance shutdown; but conservation-in-perpetuity just to make more water available for growth lacks that romantic appeal.
For many of us, the ‘romance of the river’ has probably shifted 180 degrees over the past half century to a belated appreciation for the ‘natural river’: the Colorado River that once flowed to the ocean in a two-month flood and watered a beautiful wild delta, the river that would flow through a resurrected Glen Canyon if the dam were taken down, et cetera. This eco-rec perspective nurtures the belief that the world would be a better place if we would ‘just stop digging’ and leave it to nature to heal itself from our efforts. This idea has the ‘radiant color of romance’ for many of us, but it also has its underlying naked facts – not least of which are nature’s extreme remedies for a swarming species overpopulating its resource base.
I tend to think, myself, that, yes, we can’t stop now with our tinkering and meddling; we are all too deeply into this love-hate relationship with nature. Just as we will continue to thwart nature with vaccines against its leveling pandemics, we will continue to try to keep passable water in the pipes and faucets, on the fields, and in the recreational reaches for an ever-growing population because that is who we are; it’s what we do.

Heather Brubaker had a sprawling yard of Kentucky bluegrass at her home in Longmont. Mowing the turf took her more than two hours. During summer, her monthly water bill jumped to $400.
To what good purpose, she asked herself. “It’s not really doing anything for anybody. And the grass is not native to Colorado,” she said.
Three years later, the lot at the corner of a cul-de-sac has not shrunk. Most of it remains in grass. But in increments, Brubaker has started replacing the thirsty turf with waterwise landscaping, also called xeriscaping or Coloradoscaping.
Cactuses and rocks do not define this new front yard. Colorado’s Front Range has a semiarid climate, but it’s not in the Mojave Desert. The result has spurred Brubaker’s neighbors to inquire as to her landscaper. “I tell them that my children and I have done most of the work,” she said.
Brubaker’s front yard is part of a broad and accelerating shift in Colorado’s towns and cities. Many homeowners and some businesses have started replacing lawns of Kentucky bluegrass and other varieties of thirsty cool-weather turf with vegetation that needs less water.

Outdoor water use constitutes roughly half of the water used in Colorado’s towns and cities. Many water utilities have offered rebates for these water-saving landscape shifts, reasoning that more-efficient use of existing water supplies will be far cheaper than development of new sources to meet growing populations. This reduced demand can also insulate them from the extremes posed by a changing climate.
Kentucky bluegrass and other cool-weather grasses are imports from wetter climates. Philadelphia, for example, gets 44 inches of annual precipitation. Even Oklahoma City gets 36 inches. Denver averages 15.6 inches. Bluegrass requires between 24 and 29 inches of water in the metropolitan area. Waterwise landscapes can reduce outdoor water use by half and, depending upon choices, even more.
Change, however, can be hard. There’s the sod itself. Once established, it is very difficult to remove. For most homeowners, that’s the most arduous task in a landscape conversion. Deciding what to plant in place of the thirsty grass can also be perplexing.
Brubaker started in 2021 with a narrow 100-square-foot strip along her front porch. She had volunteered for research being conducted by a team from Colorado State University that wanted to see how well pollinator-attracting plants would grow along the dripline of her front porch without supplemental irrigation. She now has many more buzzing visitors.
Emboldened by that success, Brubaker then applied for grants offered through Longmont’s municipal water provider. In two sequences, each involving sod removal and then plantings, she replaced other and larger portions of her front yard. The new section will need only half the water of before. She also created a place for whiling away languid summer evenings around a fire pit.
After rebates, she has spent $1,500, which will be recouped in time with reduced water bills.
Crucial to the success of Brubaker’s transformation was Boulder-based Resource Central. Spawned by the 2002 drought, the nonprofit’s first and still most popular program is called Garden In A Box. Designed with the aid of landscape architects, these do-it-yourself kits include quart-size perennial plants, plant-by-number maps, suggestions for seasonal maintenance and recommendations for water.
You want variety? This program has it. Consumers have at least six choices based on preferences for colors, full sun or shade, and whether attracting pollinators is a goal. Each box also delivers instructions about spacing and soils. Too sandy? Too much clay? How can it best be amended? Orders are made in March for May and June plantings, and again in June for August and September plantings.
“Everything a person needs to get started is included in their packaging, and it’s laid out very simply about what plants to put together and how to maintain them,” said Brubaker. “If you’re a novice, you can still do it easily with all the education that they put into the Garden In A Box program. It really made me want to try it.”

Making it easy to conserve
Neal Lurie, executive director of Resource Central, said the nonprofit seeks to meet people where they are. Often, they are pressed for time and not fully knowledgeable. Learning about how to transform landscapes can be overwhelming.
“If you make it easy to conserve water, they will do it,” he said. “If you make it really difficult, then they will come back to it when they have time. That is the reason that so many people continue with their current landscaping year after year. It takes time to make changes.”
Resource Central this year expanded Garden in a Box offerings by 30% — and still sold out in just four weeks. This year, the nonprofit distributed 13,000 boxes while working with 47 municipal and other partners for its various programs from Fort Collins to Pueblo. It secures its plants from local nurseries who agree to grow the sets without aid of chemicals that will harm pollinators.
Those ordering can pick up their choices at central distribution locations. For example, volunteers and staff quickly delivered the boxes to cars and pickups that made their way through a queue in the parking lot of the Westminster Municipal Building on a Saturday in August. Customers arrived when they wished. Waits at fast-food restaurants are often longer.
Turf removal is among Resource Central’s newer programs, a result of focus-group research that in 2019 found it was a key reason that even more people didn’t convert their lawns. Sod can be removed in several ways. All have challenges or difficult choices.
Convinced this was a needed service, Resource Central reached out to more than 30 landscape firms but found no potential partner. “The reason is that landscape service companies are in the business of mowing lawns, not removing lawns,” said Lurie.
Undeterred, Resource Central launched the service and this year removed 600 lawns, among them the plot at Brubaker’s house. This relieves homeowners of the hard part, leaving them with the fun of planting and creating. The removed turf is composted by A1 Organics and other companies.
The Colorado Water Conservation Board in September awarded Resource Central $1.6 million for turf replacement and removal. The two overlapping grants were the largest for water conservation ever awarded by the state agency. The terms require Resource Central to expand its water-conservation programs to new participants and communities. The Western Slope is one of the targeted regions.
“Our vision is to help make beautiful waterwise yards the new norm in Colorado,” said Lurie.
In many ways, Brubaker is typical of those wanting to shift their landscapes in that she hopes to be part of the answer to the West’s water limits. “I know we have a water crisis, and we have to conserve water,” Brubaker said.
She also wanted to provide “places for the bees.” In that, she has much company. Concern about pollinators ranks third among motivations for Resource Central customers, up from seventh a few years ago. Native vegetation does that.
Once established, maintenance of native grasses can be far easier. Other low-water landscapes, though, can still require considerable work.
There’s also this: The goal of a lawn is to grow something that, once harvested, is promptly thrown away. To some, that amounts to silly.

Attracting pollinators and reducing water use motivated Lois Witte. A retired water attorney, she decided last year that with her kids on their own, it was time to replace plants in her front yard with plants mostly native to the region.
Plant species with flowers from elsewhere, such as the East Coast or Europe, may attract bees and insects, said Witte. But plants native to the region will attract far more insects. After all, they evolved together.
To kill the grass, she and her husband, Scot Kersgaard, began in the late summer of 2022 using what is called a lasagna method. First came cardboard, then wood chips, followed by horse manure that a friend with a barn full of it was only too happy to share. On top of that were more wood chips, then dirt and pea-size gravel, called squeegee. Nine months of this method killed the grass — but not the bindweed.
By late this past summer, Witte’s work was enough to spur praise from neighbors out for evening walks. Little water will be needed once the new plants are established. Until then, however, they can take more water.
So, what spurred Witte and her husband? “In general, it’s a good idea, living in a semiarid environment,” she said of low-water landscapes. “We shouldn’t just be throwing water on the ground.”
When chaos can be good
In south Denver during August, a street corner proved to be an ideal place to meet women — and a few men, too — who loved talking about birds and bees. They were on a tour organized by the Front Range chapter of the Wild Ones, a national organization devoted to the transformation of outdoor places to habitats for native species.
“We’re not going to save the world, but we’re going to do our part,” said Vicki Saragoussi Phillips. After she and her husband, Rick Phillips, began converting their Kentucky bluegrass lawn, water use dropped from 45,000 gallons a month to 15,000. They expect even less water use once the garden becomes fully established.
Vicki described her yard as a place of chaos. Vegetative chaos, she believes, is good. Most front yards in their upper middle-class neighborhood, near South Colorado Boulevard and Interstate 25, suggested a different aesthetic. They were deep green, possibly the result of chemical treatments. They were also mowed with the care that a shirt might be pressed to eliminate wrinkles.

A young woman from the neighborhood, pushing her baby in a stroller, confided to the couple that when she rounded the corner to see their yard, she felt liberated.
Resource Central classifies most of its customers as early adopters. The nonprofit hopes to see their enthusiasm for alternative landscapes expand to create a paradigm shift. And if that helps save water — well, so much the better.
“Just say no to lawns and exotics,” Leslie Klusmire said in response to a Facebook post. She lives in Monte Vista, where she now has a yard in its third year of restoration to native plants. If some neighbors were skeptical about the weeds of spring, later they were admiring her wildflowers.
“If you look at my meadow now, it’s alive,” she said in early October. “It’s full of butterflies and bees and everything. That’s the point, to create an environment for everything.”
This is not new for Klusmire. Her father, a landscaper for Caltrans, the transportation agency in California, talked frequently about how imported grasses wasted water. Studying landscape architecture at Cal Poly Pomona in the 1970s, Klusmire got the same message.
For many homeowners, finding a contractor can be a challenge. It was for Lakewood resident Rebecca Cantwell.
Cantwell grew up in Denver during the 1950s, a time of drought that resulted in Denver Water going forward with its boring of the Roberts Tunnel and the damming of the Blue River, creating Lake Dillon. Denver supplies water to Lakewood, a city of 157,000, and about half of that water comes from the Blue and other Colorado River tributaries.
“The crisis in the Colorado River is waking up a lot of people, but our long-held assumption that everyone deserves a bluegrass lawn is just not really OK anymore,” she said.
Cantwell knew she didn’t want rock and juniper bushes to replace the grass. “That’s a false choice,” she said. “I wanted something beautiful.”
She finally found a landscape contractor to execute her vision, but it took awhile.

In another part of the metropolitan area, professional landscaper Kevin Cox has been eager to help homeowners and businesses shift to what he calls “sustainable landscaping.” That generally involves eliminating all cool-weather, high-water turfs except in areas where specifically needed.
His company, Centennial-based Professional Landscape Services, has a dozen large commercial clients, a few dozen medium to smaller commercial accounts, and 80 to 90 residential homes across the metro area, including Castle Rock, Aurora and Denver.
Mowing bluegrass is part of what Cox’s company does. But he also suggests landscape alternatives. When he does, he sometimes gets pushback.
“Everyone still wants their green grass. They say, ‘I don’t want it to look like Arizona.’ I’ve heard that a thousand times,” said Cox. “The other thing I hear is the amount of money it costs to rip out grass. They say, ‘That buys a lot of water.’”
Pay now or pay later, Cox tells them. Water will only get more expensive over time.
Beyond money, Cox sees what he calls low-water landscapes being the moral high road. “It just starts with ethics. Water is a finite resource,” he said.
Although a good case can be made for keeping some cool-weather grasses, such as for ball fields and places where toddlers play, Cox finds much of it wasteful.
“I mean, some of this grass nobody even looks at. We’re the only ones that look at it. It’s just there for us to mow, especially in some of these people’s backyards. They’re not even there half the year.”
The best way for Front Range cities such as those where his customers live, Cox said, is to do it right the first time. When new homes and business parks are developed, they should create landscapes that use less water. Led by Aurora and Castle Rock, more jurisdictions are deciding that it’s better to get it right first instead of correcting later. And in early 2024, legislators are almost certain to hear a bill that would make that state policy.
Next in this series: Aurora, Castle Rock and other municipalities in Colorado have aggressively limited new water-thirsty turf. Should the state have a broader role? Legislators in January will take up a bill that would impose restrictions on new water-thirsty turf everywhere. Expect a lively debate about state vs. local control.

Nov 22, 2023
This story, a collaboration of Big Pivots and Aspen Journalism, is part of a series that examines the intersection of water and urban landscapes in Colorado.
Between 50% and 60% of Coloradans live in housing governed by homeowners associations, commonly called HOAs. Squeezing water devoted to urban landscapes must necessarily involve these neighborhoods.
It’s already happening but, so far, mostly on the edges. A case in point: a small HOA in Greeley called Bittersweet Pointe.
“We keep saying that all the other HOAs are pointless,” Sandy Bertch, president of the board of directors, joked as he led visitors to a hillside on the edge of the HOA’s commons area.
There, three-fourths of an acre of Kentucky bluegrass had been replaced this year by a mixture of blue grama and buffalo grass. With a summer of watering bills now in hand, Bertch estimates that the HOA needs 60% less water to irrigate that section. More turf replacement will occur on the HOA’s 2.5 acres of common ground, Bertsch promised, now that the efficacy of the native grasses has been demonstrated.
The HOA is among the smallest you’re likely to find. It has 11 duplexes, or 22 units altogether, all of whose residents are retired. It is self-managed, unlike most HOAs, which employ property management firms.
Ron Mettler, a retired electrical engineer, was president of the board when he brought up the subject of turf conversion. He got immediate pushback. “Don’t you touch that green grass. That’s why I am here,” said a resident, who has since died.
Finally, last year, consensus was achieved. Costs were crucial. The retirees will save money in reduced water bills and won’t need to mow the difficult hillside as frequently.
Making the decision easier was the city of Greeley’s incentive: $1 a square foot for removal of Kentucky bluegrass in addition to rebates for water efficiency.
Clinching the deal was the shared perception of growing water scarcity. Homeowners agreed that they needed to do their part in lessening demands.
“These two are poster children,” Ruth Quade, Greeley’s water conservation administrator, said of Mettler and Bertsch. “The key to a successful project is having one or two champions, and that is what these two are.”
Every turf conversion project needs a champion, says Ruth Quade, water conservation administrator for Greeley. This lawn of this Presbyterian church has been partially replaced with pollinator-friendly vegetation. Photo/Allen Best
Replacing Kentucky bluegrass and other cool-weather grasses with native grasses and other less-thirsty species will not solve all of Colorado’s water problems. Nearly 90% of water in Colorado goes to agriculture. Only 7% of the state’s water gets used within towns and cities, and roughly half of that goes to outdoor use for lawns, gardens and other urban landscaping.
So, why does it matter? For one thing, it’s very expensive, and politically fraught, for cities to develop new water sources, usually from distant locations. Treating that water to potable standards is expensive, too. Water used indoors, which is largely contained in pipes, can be recycled. Water engineers calculate that 85% of water used for outdoor landscapes is lost because of evaporation and other causes.
All of this has water providers looking to focus on water devoted to discretionary outdoor use in road medians, business parks, homes and common areas. Experts say this transition to less water-demanding landscapes in urban areas will take many years.

How did thirsty bluegrass become the landscaping default, the cultural norm in Colorado and elsewhere?
“Nowhere in the world are lawns as prized as in America,” Michael Pollan wrote in an essay published in The New York Times Magazine in 1989. “In little more than a century, we’ve rolled a green mantle of grass across the continent, with scarcely a thought to the local conditions or expense.”
In his essay, “Why Mow? The Case Against Lawns,” Pollan shared that when he was a child growing up on New York’s Long Island, his father defied convention and refused to mow the turf at the family’s tract house. The turf grew tall enough to flower and seed, something impossible with mowed lawns. “The lawn rippled in the breeze like a flag,” wrote Pollan.
Neighbors saw something else. Some instructed their children not to play with the young Pollan. Later, when he got a lawn himself, Pollan began mulling the purpose of lawns. In this suburban paradise, he concluded, such individuality was unacceptable.
Pollan and other writers have traced our modern idea of a lawn to the early 17th century. In at least one telling, aristocrats wanted clearings around their castles for defensive purposes. They either had animals graze it or dispatched servants with scythes to keep the grasses low.
The idea of grassy lawns around homes was transferred to the United States in the mid-19th century. At first, it was limited to the American aristocracy. Thomas Jefferson put in a lawn at Monticello. So did other wealthy landowners. But for Americans of lesser means, yards were devoted to more functional pursuits, such as the growing of vegetables or the keeping of pigs and other animals.

“Turf War,” a 2008 essay by Elizabeth Kolbert published in The New Yorker, identifies Andrew Jackson Downing as a seminal influencer as the masses began to embrace lawns. In his 1841 book, “A Treatise on the Theory and Practice of Landscape Gardening,” Downing, based in New York, took aim at the dowdy rural landscapes of his familiarity. He equated personal self-improvement with gussied-up front yards.
“In the landscape garden, we appeal to that sense of the Beautiful and the Perfect, which is one of the highest attributes of our nature,” Downing wrote. Essential to that perfect garden, Downing wrote, was an expanse of “grass mown into a softness like velvet.”
Others spread the gospel. Frank J. Scott, in an 1870 book titled “The Art Of Beautifying Suburban Home Grounds of Small Extent,” wrote that “a smooth, closely shaven surface of grass is by far the most essential element of beauty on the grounds of a suburban house.” Frederick Law Olmsted deployed the broad lawns of Central Park and also planted grass in some of our first suburbs.
Technology also played a role. In 1830, a textile engineer in England adapted a carpet cutter to create the world’s first reel lawn mower. After an improved design in 1870, hand-pushed lawn mowers were produced by the tens of thousands annually. In 1893 came a patent for the first steam-powered mower. We were well on our way to the Saturday ritual many people know so well. “Over time,” wrote Kolbert, “the fact that anyone could keep up a lawn was successfully, though not altogether logically, translated into the notion that everyone ought to.”
Kolbert further identified the role of what farmers call inputs. To get potassium and other essential elements to spur growth, farmers over the ages had used everything from human dung to ground-up bones. In Europe, some robbed human graves for the skeletons. On the American Great Plains, bison were shot, their bones piled high and shipped to the East Coast.
Costs of waging war on weeds
In 1909 came an invention in Germany with profound but conflicting implications. Fritz Haber, a chemist who later won the Nobel Prize, figured out an economical way to synthesize ammonia from atmospheric nitrogen.
One result: explosives and gasses used to help run up the death toll in World War I to 20 million. Another: the ability to create fertilizer that, when applied to fields, enabled the world’s population to expand by several billion more than it probably would have otherwise.
This synthesized fertilizer could also be applied to turfgrass to counteract the seasonal cycle. By tricking the plants into putting out new growth, wrote Kolbert, fertilized grass could become ever-green. Other chemicals could quell the yellow blemishes of dandelions and every other shade of plant deemed a weed. That includes clover, which otherwise has value for fixing nitrogen in the soil. Such is the cost of having unadulterated grass.
By the time baby boomers were mostly toddlers, the idea of a perfect lawn had swept the country, even to the smallest of Colorado towns and cities. Along the shores of the Atlantic Ocean, Abraham Levitt, the namesake for the Long Island town, declared that “no single feature of a suburban residential community contributes as much to the charm and beauty of the individual home and locality as well-kept lawns.”
In “The Lawn: A History of an American Obsession,” Virginia Scott Jenkins pointed to the export of this idea to deserts of the Southwest and also to the Middle East. “Even the American community in Saudi Arabia has front lawns in the middle of the desert,” she wrote.

Perfection was possible — but at a well-known cost. Rachel Carson, in her 1962 book, “Silent Spring,” described the risk to human health posed by indiscriminate pesticide use. This, wrote Kolbert, inverted the calculation about the meaning of a well-tended, unblemished lawn. “Instead of demonstrating that a homeowner cared about his neighbors, a trim and tidy stretch of turf showed that he didn’t,” Kolbert wrote.
What then? If shaved lawns of green no longer represent civic virtue, what should take their place? That’s the question now being addressed in Colorado and many other places.
Perfect lawns also bump up against a hard hydrologic reality in Colorado. It is the nation’s seventh-most-arid state, and the story of the 21st century has been of a warming, drying climate.
Cities with growing populations exist in this shifting axis between supply and demand. They’re looking to conserve water in the most-cost-effective ways. To succeed, some of this must necessarily involve homeowners associations.
Private governments
Homeowners associations have been described as private governments enforcing covenants among homeowners. Colorado as of 2022 had 10,510 HOAs with 2.4 million residents, according to the Community Associations Institute, a national organization. Most are managed by private companies. And, according to detractors, they tend to be stuck in their ways.

Before George Teal became a Douglas County commissioner, he was a member of the Castle Rock City Council for 6½ years. Because the city was heavily reliant on a large but unrenewable underground aquifer, it wanted to encourage low-water landscapes — what it calls ColoradoScapes.
Homeowners associations resisted, said Teal. He cited “just numerous examples” given to the City Council members each year of homeowners being told by their HOAs that they could not rip out their turf. That included his own neighborhood and HOA, Crystal Valley Ranch, one that he describes as consisting of mostly working middle-class people. A change would have required a 65% vote. He similarly cites another HOA, Woodland, which consists of more-affluent residents.
“It became kind of a rallying cry on the council,” Teal said in a recent interview. “What could we do to get HOAs to accept the more water-smart landscape methodologies that were being advocated by our water utility?”
The answer was nothing. Local governments did not have the power to curb HOA powers. It had to be done at the state level.

In 2019, Colorado legislators passed the first of four laws that do so. House Bill 19-1050stipulates that it is contrary to public policy for common-interest communities, such as HOAs, to “prohibit or limit installation or use of drought-tolerant vegetative landscapes, or require cultivated vegetation to consist wholly or partially of turf grass.”
The law did allow HOAs to adopt aesthetic guidelines.
In 2021 came another law, HB21-1229. It required HOAs to allow artificial turf in backyards and also solar panels, once again subject to “reasonable aesthetic guidelines.”
These steps were applauded by Jody Beck, an associate professor in the College of Architecture and Planning at the University of Colorado Denver. “Extensive green lawns are almost never an appropriate expression of responsible citizenship in the arid West, if by responsible citizenship we mean the conscientious use of limited shared resources,” he said.
In 2022, legislators did not specifically target HOAs and water. Instead, HB 22-1151 instructed the state’s chief water agency, the Colorado Water Conservation Board, to develop a program for the voluntary replacement of turf in cooperation with local governments and appropriated $2 million for that work. After administrative expenses, $1.5 million has been awarded to more than two dozen local jurisdictions in Colorado.
Later that same year, legislators were advised that another law was needed to close a loophole in the 2019 law. At least some HOAs had used the clause that gave them aesthetic discretion in reviewing plans to effectively stall or even block turf-replacement projects proposed by owners of single-family homes.
Proponents have cited abundant anecdotal evidence. The most-direct evidence came from a survey conducted in 2021 by Western Resource Advocates in cooperation with the city of Greeley. The survey was intended to reveal the primary barriers keeping residents from replacing some or all of their grass with water-wise landscaping. Cost? Expertise? Aesthetics?
Nothing was asked by the survey about HOAs, but when allowed the opportunity to describe the challenges, 41 of the 720 who completed the survey cited their HOAs.
A step in the right direction
This year’s bill had bipartisan support. “In practice, we see barriers to people who want to replant their front yards with more water-conserving plants,” said state Sen. Sonya Jaquez Lewis, a Democrat from Longmont, when introducing the bill, HB23-178, at a legislative committee hearing.
Another bill sponsor, Sen. Perry Will, a Republican from New Castle, who represents seven Western Slope counties, cited demands on the Colorado River. “This will not save all of Colorado’s water, but it is a step in the right direction.”
The bill requires that HOAs must select at least three preapproved water-saving landscaping templates that residents can follow. Residents and HOAs can choose to go for other designs, but at least three options must be preapproved. There’s no real excuse for saying no.
Part III. How bluegrass lawns became the default for urban landscapes Some Colorado HOAs have started moving the needle, while state legislators prod others into water-wise landscapes; plus, a history of how we arrived at a certain idea of landscape perfection.
Part IV coming. The outliers of the native grass movement. Some Coloradans have taken it upon themselves to remove their thirsty turf, and a non-profit is helping them do it.
Part V coming. Do we really need bluegrass in road medians? And Aurora, Castle Rock and Denver push for sharper limits on what can be installed in the first place.
The state’s most significant organization representing HOAs didn’t bother to show up to testify one way or another. The bill passed with minor opposition grounded in questions of local control.
Teal, who testified in both legislative committee hearings, said he would have preferred local control. But, given the sweeping powers of HOAs, he believed the state had to step in order to aid municipalities. “Water conservation and water reuse have become primary goals of the town of Castle Rock and, I think, soon will become one of our primary policy goals here in (Douglas) County as well,” he said.
Robert Greer, a Denver attorney, helped draft the bill that he says closed the loophole in the 2019 law that was big enough to “drive a solar system through.”
He was driven, he said, most powerfully by a desire to create urban landscapes that accommodate pollinators of the natural ecosystem. His sentiment is part of a broad and powerful undercurrent in Colorado’s push to replace Kentucky bluegrass, perennial ryegrass and other imported cool-season varieties. It’s not all about saving water.
Also testifying was Chris Marion, who began work in 2017 as a water conservation specialist. After getting a master’s degree in sustainability planning from the University of Colorado Boulder, he founded a company called 3.0 Management. It provides management for about 40 HOAs in metropolitan Denver.
Marion sees an opportunity for HOAs and other places with large expanses of turf to rethink their landscapes. Irrigation systems installed 40 to 50 years ago need replacement or updating, Some HOAs are poorly funded for replacement of leaking pipes and so forth.
“It’s not only the cost of water, but the associated maintenance costs of older grass,” he said.
Something else is going on, a shifting cultural norm. The impetus for expanses of Kentucky bluegrass that we see today was “simple, cost-effective landscaping, which was primarily bluegrass.” Now, said Marion, younger generations in particular have become at least aware of “the concept of personal ecological footprints.”
That shift in attitudes is now being integrated into governance of HOAs.

Lessons from Fort Collins
In Fort Collins, Colorado’s fourth-largest city, with a population of 170,000, residents of the Oak Ridge VII homeowners association were informed in 2018 that they would have to pay $18,000 more annually for water.
When the tap fee for the commons area owned by the 52 members of Oak Ridge VII and two other HOAs had been assessed several decades ago, it assumed a maximum volume of water. Water use for that commons area had been rising, exceeding the maximum. Homeowners had to figure out how to use less water or pay the greater fee.
The 10.1-acre commons area consists of expansive lawns interspersed with trees that turn bright with warm colors during the fall. It also has a soccer field and a 1.4-acre detention area designed to hold stormwater. Water can get 1 foot deep when it rains, as it did prodigiously this year. In previous drier years, though, Kentucky bluegrass required irrigation to maintain its well-coiffed look.
In 2019, HOA directors approved conversion of the bluegrass to buffalo and blue grama grasses. A survey of homeowners found that 80% supported the shift. Later, another problem area — a small south-facing hill that was difficult to irrigate and mow — was also replaced. Water use for the park has declined to 3.1 million gallons per year — the original projected need when the subdivision was created 30 years ago — from 4 million to 5 million gallons per year.
The full cost of the landscaping work of $86,000 was defrayed by $57,000 in grants from Northern Water, the bulk water provider, and the city of Fort Collins. “We never could have done it without the grants,” said Susan Gilbert, a homeowner who championed the shift.
“People have loved it,” said Gilbert during a walk through the park. A pollinator park along the concrete pathway, buzzing with bumblebees, has been particularly popular.
Weeds can be a problem in conversions, and this was no exception. The HOA had its landscaper apply herbicides in some spots.
“Everybody gets a little jittery when we do spraying,” said Milan Hanson, president of the HOA’s board of directors.
“During the first year or two, I think every native grass conversion looks pretty bad,” he added.
Tony Koski, a professor of turfgrass sciences at Colorado State University and described by many as the guru of water-wise landscaping in Colorado, condones the use of herbicides as essential in landscape conversions, but he counsels care and transparency.
Native turf grasses green up more slowly in spring and turn brown more rapidly in autumn, as was evident at this commons area of a homeowners association in Fort Collins in mid-October. Kentucky bluegrass and other imported grasses have a longer season of green. Photo/Allen Best
The need for herbicides diminishes as the native grasses become dominant over the course of about three years. But homeowners planting native grasses should expect to see the new turf brown more quickly in the fall and green up more slowly in the spring.
Still, Oakridge residents have seen enough to think about converting other places to native grasses.
What caused the increased water use? It’s not uncommon, said Frank Kinder, water-efficiency manager for Northern Water. The agency distributes Colorado River water to providers along the northern Front Range.
“People are watering earlier and watering more during a year to keep up the appearance,” said Kinder. “The landscape may take up to 120% of the previous amount in order to keep looking like what people want it to look like.”
HOAs undertaking conversions can have different motivations: costs, concerns about climate change, a desire for landscape diversity or easier maintenance. “Bluegrass takes a lot of work to meet certain expectations,” said Kinder.
Key lessons from Fort Collins and Greeley HOAs are that turf replacements take time and are most easily accomplished with partnerships. Key in both cases, too, were grassroots champions.
Very likely, you will also begin to see more and more cool-weather turf converted to low-water landscapes in Colorado’s HOAs. That’s exactly what some of those who helped draft some of Colorado’s recent laws intended. Call it a grassroots movement.
Next: Colorado allows sales of only low-flush toilets to better conserve limited water. What role should the state have in reducing water use allocated to urban landscapes? A task force has been studying the state’s options and opportunities.

The Western Slope delivers 70% of the Colorado River water. So why do Aspen, Vail and other places want to replace thirsty turf?
This story, a collaboration of Big Pivots and Aspen Journalism, is part of a series that examines the intersection of water and urban landscapes in Colorado.
If you’ve ever slipped and spun your way across Vail Pass through a wet, heavy snowstorm, you can be excused for wondering how Eagle River Valley communities could ever have too little water.
Vail and its neighbors do have that problem, though. It has become evident in the growing frequency of drought years in the 21st century.
U.S. Drought Monitor July 23, 2002.
First came 2002. Water officials, verging on panic, restricted outdoor water use. The drought was believed to be the most severe in 500 years. Fine, thought water officials as rain and snow resumed, we’re off the hook for at least our lifetimes.
West Drought Monitor map October 12, 2021.
In 2012 came another drought, one nearly identical in severity. More bad years followed in 2018 and 2021. The Eagle River normally chatters its way down the valley through Avon and to a confluence with the Colorado River near Glenwood Canyon. In those bad, bad drought years, it sulked. The shallow water was hot enough to endanger fish.
“New plot using the nClimGrid data, which is a better source than PRISM for long-term trends. Of course, the combined reservoir contents increase from last year, but the increase is less than 2011 and looks puny compared to the ‘hole’ in the reservoirs. The blue Loess lines subtly change. Last year those lines ended pointing downwards. This year they end flat-ish. 2023 temps were still above the 20th century average, although close. Another interesting aspect is that the 20C Mean and 21C Mean lines on the individual plots really don’t change much. Finally, the 2023 Natural Flows are almost exactly equal to 2019. (17.678 maf vs 17.672 maf). For all the hoopla about how this was record-setting year, the fact is that this year was significantly less than 2011 (20.159 maf) and no different than 2019” — Brad Udall
Colorado River flows have declined 20% since 2000. Having water rights is not enough. And the future looks even hotter and, because of that heat, drier. Brad Udall, a senior scientist and scholar at Colorado State University, warns of up to 20% additional flow loss by midcentury.
Average temperatures in the Colorado River Basin are projected by the U.S. Bureau of Reclamation to rise 5 to 6 degrees Fahrenheit during the 21st century. The agency projects slightly greater increases in Colorado and other upper basin states.

In Vail, managers of the Eagle River Water and Sanitation District have decided they need more storage. They plan a 1,200-acre-foot reservoir near Minturn called Bolts Lake. That compares with the 257,034-acre-foot storage of Dillon Reservoir. At that capacity, this new reservoir will be the most cost-effective way to ensure resilience as the climate becomes more variable. With the reservoir, they hope to capture water during high-runoff years for use in the district’s service territory from Vail through Edwards.
Demand reduction will be another tool of growing importance in a hotter, sometimes drier climate. Managers hope to reduce water demand in the district 5% by 2026 even as new housing, especially more affordable units, gets built. That’s 400 acre-feet per year.
The most productive place to wring these savings will be in water used for outdoor landscapes. Only 25% — or even less — of water applied to lawns returns to streams and rivers compared with 95% of water used indoors.
Siri Roman, the district’s general manager, said short-term change, such as restricted lawn watering in drought years, can be a strategy. But her district wants to effect permanent change.
“It’s not about drought years,” she said. “It’s about a drying climate. We have to get people to shift their attitudes, to know that water is getting to be more scarce.”
Roman’s district, like other water utilities in Colorado, is targeting nonfunctional turf. Precise definitions vary, but nonfunctional generally refers to grasses that require large volumes of water to irrigate but rarely see human feet except when mowed. It is also described as aesthetic turf.
Three years ago, Eagle River Water began offering rebates of $1 per square foot to customers willing to replace thirsty lawns with landscapes that use less water. Using state aid, the district this year bumped up the incentive to $2.
“We are not saying it needs to be stone and look like Arizona,” Roman said.
Directors of the district in October also agreed to new tiered rates that will discourage high-volume consumption.
Other Western Slope communities have also set out to discourage thirsty landscape choices. Motivations vary, but for many, there is also acknowledgement of the need to walk the talk of water conservation expected of Front Range communities. “That is something I hear a lot from communities I am working with,” said Marjo Curgus, a consultant.
‘Lawn Begone’ in Durango
Almost a decade ago, Steve Harris, a water engineer in Durango, summoned the local news media to his house to watch him remove sod from his front yard. He also had bumper stickers produced: “Lawn Gone.” In an editorial, the Durango Herald offered an alternative: “Lawn Begone.”
Harris believed that Colorado needed to make clear that decorative lawns had less value than agriculture. He worked with his state legislators to draft a bill that would have limited transfers of agricultural water to cities if that water went to lawns. As for his own lawn, Harris thought that he and others on the Western Slope couldn’t just pay lip service to this idea.
At the Colorado Capitol, the bill introduced in 2014 by then-Sen. Ellen Roberts and then-Rep. Don Coram was quickly shelved. Local governments objected. So did ag producers who thought state legislators had no business blocking their abilities to sell water rights.
Instead, the idea was directed to an interim committee for further study. Bills sometimes get sent there to die. In this case, the conversation continued, as Roberts had intended.
Since then, legislators have adopted several laws. A bill that passed in 2022, House Bill 22-1151, does not institute a prohibition but instead allocated $2 million to the Colorado Water Conservation Board, $1.5 million of which went to local jurisdictions to spur voluntary replacement of irrigated turf.
The law asserts that for every 100 acres of turf converted to water-wise landscaping, up to 200 acre-feet of water can be conserved. The act defines water-wise landscaping as a water- and plant-management practice that emphasizes using plants with lower water needs.
Whether that much water gets saved also depends upon whether irrigation systems are changed to match the lesser water needs of the new landscapes. Grass that needs 12 inches of supplemental water per year need not continue to get 25.
All that funding has now been allocated. On the Western Slope, the municipalities of Cortez, Glenwood Springs and Frisco were awarded funds as was the Eagle County Conservation District. The state agency said 25% of turf-replacement funds were for Western Slope entities.
Rep. Marc Catlin of Montrose and then-Rep. Dylan Roberts of Frisco, two of the four prime sponsors, are from the Western Slope. Another prime sponsor, Sen. Cleave Simpson of Alamosa, now has a district that encompasses southwest Colorado, while Roberts has become a senator.
Without state funding, Montrose County approved grants for seven turf-replacement projects.
“From the start, I thought this initial effort might have more value from an education and outreach perspective than actual water savings,” said Justin Musser, the county’s natural resources manager.
Projects were chosen based on various objectives. For example, do the new landscapes provide energy savings or wildlife benefits? “We are not overly prescriptive,” said Musser. “If you have a good plan that references standards from the Colorado State University Extension or another reputable source, the application gets a higher ranking.”
Why would Montrose County be interested in yanking sod to save water?
“It’s important that we look at these types of things across the Colorado River basin,” Musser said. “We would want people in California and Arizona and Nevada to be looking at these types of programs, too. I think it makes sense for a place like Montrose County to be conserving water as much as we can, too.”
But, he added, this is “one part of a very complex issue.”
As this diagram (Snake Diagram) shows, native flows in the Arkansas River Basin are dwarfed by the amount of water in West Slope basins (created by the Colorado Water Conservation Board).
Droughts versus aridification
The Western Slope of Colorado produces 70% of the water in the Colorado River, according to the Colorado River Water Conservation District. Some of that water stays in Colorado. About half of the water for Front Range cities comes from the Western Slope. Yet more of the Colorado River gets diverted to farms in the South Platte and Arkansas river valleys.
And, of course, water from the Western Slope flows downstream to farms and cities in Arizona, California and Nevada.
The Colorado River has infamously been falling short of meeting all demands. The river first failed to reach the Sea of Cortez in the 1960s and, as diversions in Arizona and elsewhere expanded, has ceased to reach the sea altogether since the 1990s — save for an especially engineered pulse in 2014.
In 1922, when delegates of the seven states met to negotiate the Colorado River Compact, they assumed that flows of the early 20th century would be the norm, delivering more than 20 million acre-feet. As Eric Kuhn and John Fleck explain in their book, “Science Be Dammed: How Ignoring Inconvenient Science Drained the Colorado River,” it had been a wet period.
It didn’t stay that wet, and in the 21st century it has been delivering far less water, an average 13.2 million acre-feet through 2022. Andy Mueller, general manager of the Glenwood Springs-based Colorado River District, and others have warned that continued warming could depress flows to 9 million acre-feet during coming decades. Or even less.
Grand Junction has a maze of irrigation canals but the municipal water utility gets water from a creek that flows from the Grand Mesa. Photo/Allen Best
Grand Junction more recently adopted regulations curbing water needed for urban landscaping. The city has adopted sustainability goals, “and water plays a big part of that,” said Randi Kim, utilities director for the city of 69,000 people.
Cost savings enter into the city’s calculation as it prepares for a projected 91,000 residents by 2040. The municipal utility taps high-quality water from Kannah Creek, which originates on Grand Mesa. When that is insufficient to meet demands, as the city utility projects will be the case by 2040, the city will tap the Gunnison River but will need to pay more to treat the dirtier water.
Rising heat can also drive higher demand. Grand Junction in July reached 107 degrees, tying the record that had been set just two years before. The city’s 13 highest temperatures have occurred this century.
This is but one aspect of the changing and drying climate, a process that many — including Kim — describe as aridification. “I think people realize that we have to change the way we use and manage water, and it really affects every aspect of our lives,” she said.
Grand Junction’s new regulations apply to new developments. Turf that does not meet the city’s definition of “functional” cannot exceed 15% of landscaping. The new regulations also require low-water vegetation in traffic medians and some other common areas.
Steamboat Springs, although cooler and wetter than Grand Junction, faces similar challenges. It gets 24 inches of precipitation a year, compared with 10 inches for Grand Junction. Some years, the snow along streets of Steamboat gets piled higher than the head of a rim-rattling professional basketball player.
These prodigious snowfalls have not been yielding equally impressive runoffs in the Yampa River. Several times during the longer, hotter summers of the 21st century, the river slunk to such shallow depths that water officials decreed a temporary end to fishing. It almost happened again in July before temperatures cooled and rain arrived.
“We were one day from the river being shut down again,” said Madison Muxworthy of the Yampa Valley Sustainability Council, a nonprofit. “It was crazy.”
The Yampa River at Deerlodge Park July 24, 2021 downstream from the confluence with the Little Snake River. There was a ditch running in Maybell above this location. Irrigated hay looked good. Dryland hay not so much.
Muxworthy calls the Yampa River the “life beat of our community.” The description is apt. Kayakers paddle amid the waves during runoff months, and anglers drop lines every season. There are always people along the river banks.
In 2021, heeding local sentiment, the sustainability council launched a water-conservation program focused on outdoor use. Working with the city government and Mount Werner Water and Sanitation District, the group created a guidance document for landscapes called “Yampascaping.” Four educational workshops this year were well attended.
“Citizens are really interested in this because they see the impacts from climate change that we’re already having,” said Muxworthy, her organization’s soil moisture, water and snow program manager. “It’s really easy for them to make the connection and want to do something about it.”
The Mount Werner district, which serves the base of the city’s bigger ski area, offers rebates of $1 per square foot for turf removal.
Eighty miles south of Steamboat, at a 131-unit multifamily project along the Eagle River called The Reserve, turf-removal incentives of $2 per square foot have also helped the homeowners association replace a half-acre of thirsty grasses with native vegetation. The homeowners hope to replace another 60% of the more than 4 acres of common area.
Saving water is paramount in the mind of Deb Forsline, a director of the homeowners association. She sometimes lulls her grandchildren to sleep with the soothing sound at river’s edge and, at other times, accompanies her husband on fishing expeditions, knitting while he dangles lines. “It’s about saving water for the river, not the money,” she said of the efforts to reduce water for landscaping.

Diane Johnson, communications and public affairs manager at Eagle River Water and Sanitation District, concurs. The $2 per square foot “helps move the thinking of people who have already been thinking about it,” she said.
Roman, the district’s general manager, points to the innate connection that most of her district’s 31,000 consumers have with the outdoors. “A lot of people who live here year-round know that it is irresponsible to overuse.”
A steeper staircase of water rates
After the 2002 drought, the Eagle River district adopted an inclining block rate structure. The more you use, the more you pay. The district got inconsistent results. Larger homes and those with more expansive and water-intense landscaping dropped their use in smaller percentages than smaller homes. The rate structure had been flawed, allowing larger homes to pay less per 1,000 gallons than smaller homes for the same volume of water. Different rates were needed to snag the attention of high-volume consumers.
Aspen had the same problem. It adopted tiered water rates in 2005. Managers thought the rates would discourage high volumes of consumption. But even in drought years, some properties continued stubbornly high volumes.
In 2017, Aspen adopted a new approach. The regulations require reduced water use in the landscape and irrigation plans for new and redeveloped projects. Such caps are called budgets. Like Denver and Boulder, Aspen has almost no new development of raw land. The law imposes a hard cap of 7.5 gallons per square foot of landscape. That’s about a foot of water, or roughly half of the supplemental water required in Colorado for Kentucky bluegrass. The law also requires so-called “smart” irrigation systems and alternative plants but leaves some flexibility in how developers and their consultants stay within the water budgets.
So far, 110 to 120 projects in Aspen have been reviewed, but only 15 to 20 have been executed – still too soon to discern clear results in water savings for the city, said Rob Gregor, utilities permit coordinator. Still, the city has leveled its water use and hopes to achieve even greater efficiencies in water devoted to residential and commercial landscapes. That could leave more water in Castle Creek and the Roaring Fork River, one of the goals of the program.
Durango, with 19,000 people and a projected population of 25,000 by 2035, has considered using rates to nudge high-volume users to less demanding landscapes. Justin Elkins, utilities manager, said the city hopes to encourage voluntary reductions in water use by allowing water users to monitor the volume of their use and compare it to consumption by their neighbors.
The Ute Water Conservancy District has successfully used rates to encourage water conservation. The Grand Junction-based district delivers water to rural and exurban areas of the Grand Valley from Cameo to the Utah border. Customers tend to be more responsive “when it hits them in the pocketbook,” said Andrea Lopez, the district’s external affairs manager. “As they use more water and enter into tiers that become steeper with the more they use, we usually see a reduction in use.”
That’s what Eagle River Water has done. Like Aspen, the Vail Valley has some wealthy homeowners. Under the old tier system, somebody in a smaller home paid more per gallon than somebody in a larger home, if they both used the same large volume.
Beginning in January, Roman was on the agenda of everybody from Rotary clubs to Eagle County commissioners. “Really, this is targeting our excessive users,” she told the Vail Town Council at a June meeting. “They’re the ones that are going to feel this.”
District directors in October approved the new tiered rates that intend to discourage high-volume consumption.

In Wildridge, a neighborhood on the south-facing slopes of Avon, Linn Brooks has shown what is possible in landscape conversions. Fifteen years ago, before she started transitioning her landscape, her home used 15,000 to 25,000 gallons a month. Now, it uses, at most, 7,000 gallons a month and her landscape is commanding.
The takeaway, she said, is that communities can have vibrant landscapes and protect property values – and still use less water.
Next: How did bluegrass lawns in Colorado become the default? Some trace it to the castles of Europe. Half or more of Coloradans live in neighborhoods governed by homeowners associations. Some have started to curb thirsty bluegrass, but others needed a firm nudge this year from state legislators.

Pace of transition has accelerated, deepened and broadened as headwaters state struggles to embrace limits of water supply in a warming, likely drying climate
This story, a collaboration of Big Pivots and Aspen Journalism, is the first of a five-part series that examines the intersection of water and urban landscapes in Colorado.
Like weekly haircuts for men, a regularly mowed lawn of Kentucky bluegrass was long a prerequisite for civic respectability in Colorado’s towns and cities. That expectation has begun shifting.
A growing cultural norm blesses a broader range of respectable landscapes, which require not much more water than what occurs naturally across most of Colorado. Denver, for example, averages 15.6 inches annually.
Native grasses, most prominently buffalo and blue grama, need half to one-third as much of the supplemental water a year required to keep Kentucky bluegrass — a species native to Europe — bright green. In metro Denver, for example, Westminster and Broomfield estimate that these cool-season grasses require 24 to 29 inches of supplemental water annually in addition to the 15 to 16 inches of average precipitation. Other water-wise landscape choices can also ratchet down water requirements by at least half.
Many homeowners have the additional goal of installing shrubs, flowers and other plants that attract pollinators.
The shift can be traced back to at least 1981, when Denver Water coined the term “xeriscape” to reflect landscaping choices that use less water. The drive to cut excessive water use for landscapes picked up significantly during and after the searing drought of 2002. When that drought ended, many consumers retained their new, more judicious habits of irrigation.
Now, say water providers and others, the pace of transition has accelerated, deepened and broadened. If still far from universal, Coloradans have started developing a new aesthetic around urban landscapes. What is required to be a responsible homeowner and property manager is being redefined.
With Colorado River water woes still unresolved and depletion of aquifers in the Denver Basin and elsewhere continuing, Big Pivots in collaboration with Aspen Journalism set out to understand water devoted to urban landscapes in Colorado. This is the first of five stories about this giant and probably long-term shift in how we use water in urban landscapes.
Nobody argues that this shift alone will solve Colorado’s water challenges. Water devoted to lawns and other urban landscapes constitutes just 3% to 4% of Colorado’s total water consumption. Nonetheless, that use is being questioned as never before.
Western Slope residents have long objected to dewatering of rivers and streams for lawns along the Front Range. Now, water utilities on both sides of the Continental Divide see more-judicious use of water as being the most cost-effective strategy in serving larger populations in a hotter and possibly drier climate. And many homeowners have decided that by replacing imported varieties of turf with native plants, they can be part of the solution to declining populations of pollinating insects.
Colorado legislators have passed several laws in recent years to curb standard turf-growing practices. In January, they will be asked to approve a bill that would require local governments and homeowners associations to ban the installation, the planting or the placement of new nonfunctional turf, artificial turf or invasive plant species in commercial, institutional or industrial properties. The bill takes aim at purely aesthetic non-functional turf along roads and in medians. Residential homes would be exempted from the prohibition.

Nonfunctional turf generally means grass intended to be seen but rarely, if ever, touched by human feet. For example, the Flatirons Mall in Broomfield, a hospital in Fort Collins and a warehouse complex in Aurora have broad swathes of green grass surrounding them. Another example is along the drive-up lane to an ATM at a bank on East Colfax Avenue in Denver. Cosmetic or aesthetic turf is universal.
The bill has the backing of both Denver and Aurora. They argue that replacing existing turf, a costly task, is negated if the saved water is then used for new development that hews to the old habits of landscape. Aurora, in particular, has made clear that voluntary approaches have had only marginal success.
Colorado Springs, although equally committed to reducing water use, believes that a harder but better approach will be more effective in the long term. The Colorado Municipal League, representing 270 of the state’s 272 towns and cities, has concerns. At issue is a familiar one in Colorado: state mandate vs. local prerogative.
Voluntary approaches, though, have been impressive. For example, thoughtful design can be found in abundance at Centerra, a commercial and housing complex in Loveland. There’s still bluegrass, but it tends to be minimized.
In Boulder, Resource Central began offering water-conservation services to Front Range communities during the severe drought of 2002. The nonprofit reports a rapid uptick in its lawn replacement and other programs. It now has relationships with 47 water providers who help support the nonprofit’s Garden In A Box and other programs.
“This is the first year that we have seen more than 10,000 people participating in our various water-conservation programs, which tells us that this is rapidly becoming the new norm in Colorado,” said Resource Central CEO Neal Lurie, referring to lower-water landscapes. “What happens is one person makes a change in their yard and their neighbors come over and ask, ‘What are you doing?’”
It is that neighbor-to-neighbor conversation that is driving the urban landscape changes evident to anyone moving about most Colorado towns and cities.

Growing awareness of water scarcity also drives these altered sensibilities as well as new government regulations limiting outdoor water use. Declined flows in the Colorado River figure prominently in the thinking of many individuals but also public officials.
Aurora adopted bold restrictions on water use for outdoor landscapes in 2022. No use of Kentucky bluegrass or other so-called cool-weather varieties that use higher volumes of water will be allowed at new golf courses. The same applies to new front yards, although 500 square feet or 45% of backyards, whichever is less, will be permitted. The regulations also take aim at water for road medians and curbside landscapes. Fountains, waterfalls and other ornamental water features will also be banned in new development.
Aurora Mayor Mike Coffman — whose city has the state’s third-highest population, at 400,000 — cites worries about potential diminishment of water imported from the Colorado River basin as one of several reasons for taking action. “The longer you wait, the more dramatic your decisions have to be,” he said. “I think we’re on the right path.”
At least 38 utilities and other water providers have instituted turf-replacement programs, offering incentives that in some places can reach $3 per square foot of turf removed. That’s almost double the number of jurisdictions of just a few years ago. Like Aurora, many local governments have also adopted limitations on outdoor landscaping. Broomfield adopted regulations in late August.
Doing their small parts
In southeast Denver, Meredith Slater took a break on an August morning to explain why she and her husband, Jake Hyman, earlier this year had replaced the lawn of their brick home with plants native to Colorado and nearby areas. The yellow, red and orange flowers were thick with bees and other pollinators.
“Over the last few years, I’ve come to recognize that native bees, birds and insects don’t have a place to call home in much of Denver because of all the grass and nonnatives,” Slater said as her husband used a tiller to rip out the remaining Kentucky bluegrass on the other half of the front yard. “That was part of the impetus for this.”
Slater works for a global organization called ActionAid. It operates in 40 countries, many of them in Africa and Asia, to assist farmers faced with the challenges of a warming climate. That work has made her particularly attentive to the challenge of protecting adequate water for agriculture. In Denver, she sees water devoted to lush green lawns as wasteful.
“I’m just trying to do my little part with my front yard,” she said.
Her thought was echoed by dozens of homeowners from Colorado Springs to Fort Collins to Durango who were interviewed for this series of stories. “We’re not going to save the world, but we’re doing what we can,” said a Denver homeowner.
Colorado gets 83% of its water from rivers, streams and other surface sources, while the other 17% comes from groundwater, according to the 2023 Colorado Water Plan. Agriculture uses about 90% of Colorado’s water, towns and cities 7%, and industry 3%.
Within urban areas, outdoor irrigation consumes roughly 50% of water.
Why would cities want to cut outdoor use? Motivations vary.
For most jurisdictions, conserving water through reduced outdoor use represents the cheapest way to serve larger populations. Colorado Springs Utilities, for example, serves a population of 500,000 but has expectations of serving 800,000 at buildout.
Population growth along the Front Range during the past century has been primarily satisfied by transmountain diversions. Half of the water for Front Range cities comes from the Western Slope. In theory, Colorado has undeveloped water in the Colorado River. New transmountain diversions, though, can be very expensive and problematic. Aurora and Colorado Springs, for example, completed their Homestake diversion project in 1967. Since the early 1980s, they have been seeking additional diversions from Homestake Creek, an Eagle River tributary. Conservation has been more easily accomplished.
Easier in most cases than transmountain diversions — but still difficult — has been converting agriculture water to municipal use. That’s true even in the South Platte River Basin. As The New York Times reported in a September story, the Denver suburb of Thornton began acquiring water rights near Fort Collins in 1985. Construction of a 72-mile pipeline to bring that water to Thornton residents and businesses has barely started.
A pipeline almost to Nebraska
Several of Denver’s south-metro-area cities have been unsustainably drafting the Denver Basin aquifers. Parker gets nearly 60% of its water from the aquifers; Castle Rock attributes “most” of its water from the aquifers.
Parker Water and Sanitation District, working with farmers in the Sterling area, plans to pump water roughly 125 miles across eastern Colorado. It estimates the cost at $800 million. Castle Rock may participate in that project and also has a project called Box Elder that would draw water from 60 miles away in northeastern Colorado.
Lessened demand from landscaping means less need for costly new infrastructure. It also makes water utilities more resilient in the face of drought. Landscapes can sparkle with little water. Actually, they can be even brighter at times. After all, the “perfect” lawn is a monotone, unblemished by yellow dandelions or anything else.
Still other water providers have been motivated simply by a desire to leave water in streams and rivers. That’s the case in Vail, which is landlocked with no expectations of significant expansion. There, the town has been replacing water-consumptive Kentucky bluegrass in town parks since 2019 with less-thirsty native species. This year’s projects also include removal of grass from an on-ramp to Interstate 70.
Vail’s motivation is simple: to preserve flows in Gore Creek and protect the aquatic environment, said Todd Oppenheimer, the town’s capital projects manager.
Boulder has a robust portfolio of water rights and self-imposed growth limitations. Unlike neighboring jurisdictions along the Front Range, It has no practical considerations driving landscape changes. But for 20 years, it has been participating in Resource Central’s water-saving programs. This year, the city provided each customer $500 that can be applied toward either turf removal or Garden In A Box programs.
Turf removal reflects community values, said Laurel Olsen, Boulder’s utilities engagement and outreach senior program manager. “We have decided as a community that wise use of our resources is a high priority.”

In theory, this should result in Boulder’s leaving more water in creeks. The city, however, does not have a tabulation of that.
Colorado’s state government has also been delivering nudges. State legislators in 2022 directed the state’s leading water agency, the Colorado Water Conservation Board, to develop a statewide program that would use financial incentives to encourage the voluntary replacement of irrigated turf with water-wise landscaping. That law allocated $2 million for the programs. Through early September, funding had been awarded to 25 jurisdictions with 13 others considered “eligible.” A deadline to apply for a second round of grants was in late August.
In February, Gov. Jared Polis appointed 21 members to a new Urban Landscape Conservation Task Force. He asked them to identify practical ways to advance outdoor water-conservation through state policy and local initiatives. Members must report their findings in January.
Several of the major water providers in the Colorado River basin have also agreed to reduce water for urban landscapes.
In August 2022, water providers from Denver, Aurora and Pueblo, along with those from Los Angeles and other southwestern cities, announced a memorandum of understanding. The MOU commits participating water utilities to “reduce the quantity of nonfunctional turf grass by 30% through replacement with drought- and climate-resilient landscaping, while maintaining vital urban landscapes and tree canopies that benefit our communities, wildlife and the environment.”
The MOU does not specify water savings, only the reduction in turf.
Shifting attitudes
Driven, at least in part, by the Colorado River troubles, public perceptions have been shifting rapidly.
Denver Water has conducted surveys since 2016 that ask respondents how scarce they think water is now, and how scarce they think it will be in 10 years. Survey results show a sharp uptick in concern.
“Two-thirds of people think water is scarce now, and 90% of people think water is going to become more scarce in the future,” said Greg Fisher, manager of demand planning for Denver Water.
Fisher sees a link to the “innumerable Colorado River stories” that have been published and broadcast in recent years. “We’re attaching that to climate change. And I think from what I read, it’s a lot of people asking, ‘What can I do? I now understand there’s this problem in the Colorado River. What can I do to help that?’ And I think we’re starting to show them a way that they can help.”
Denver Water in 1981 coined the term “xeriscape,” combining the Greek prefix “xero,” which means dry, with landscape. Water conservation advocates now rarely use it. They say too many people take it to mean zero-landscape, and for many, that means rocks and cactus. Yards of gravel are anathema to landscape architects. Not only are gravel yards boring, but they contribute to the heat-island effect of urban areas.
Colorado Springs-based landscape architect Carla Anderson said she constantly stresses the alternatives to turf grasses imported from other parts of the world to Colorado’s semi-arid climate.
“I have been advocating for years – not saying that grass is bad but to put it in places that make sense. A little bit of turf can go an awful long way in creating a feeling of an oasis,” she said. “The good thing is we’re getting some wonderful options to bluegrass.”
Gravel spread across lawns, such as this one in Denver, may seem like an easy replacement for turf, but landscape architects roll their eyes, as do others. Also, gravel yards contribute to the heat-island effect of urban areas. Photo by Allen Best
In her work, she sees a generational shift. Older people, generally 70-plus, tend to insist on bluegrass lawns because they see it as a status symbol. “If you have this big, sweeping front lawn, you have made it,” she said.
Younger generations, even including those in their 60s, have a broader perspective. They are less likely to assign status to a lawn.
But conversions to water-wise landscapes do take time and energy. “That is a stumbling block for a lot of lower-income people,” said Anderson.
Riding on a bus in Colorado Springs, her attention was directed toward a weedy front yard. “What would you call that?” she was asked. “An unkempt yard.”
Colorado Springs officials estimate that 30% of homes in the city are unkempt. The challenge they see is to ease the conversion to low-water yards. They hope to help foster native grasses, which use little water and, once installed, demand less maintenance.
The process of changing attitudes will take time, said Anderson. “It won’t happen overnight. We have this long affair with the bluegrass lawn in all corners of our country, and so the process of changing people’s perception of what is right and looks good, what is aesthetically pleasing, is a significant process. It is just going to take time. Unfortunately, we don’t have that much time. We need to crack down and save water in a hurry.”
A new word
As the word “xeriscape” falls out of favor, it is being replaced with new words: water-wise, water-efficient and Coloradoscape.
“There is no agreement yet” on which should be the commonly accepted phrase, said Lindsay Rogers of Western Resource Advocates, a group that has devoted substantial resources to the shift.
“We want climate-appropriate landscapes in Colorado that are verdant and beautiful and use native plants but also use less water than Kentucky bluegrass,” she said.
Westminster is unusual among Front Range cities in its small reliance on the Colorado River. The city’s water utility located midway between Denver and Boulder serves 135,000 people. Most of the water comes from Clear Creek. And it has no expectations of rapid growth, unlike Aurora, which envisions a near doubling of population in the next 50 years.
More than 80% of Westminster residents live in single-family homes and have above-average affluence. Converting lawns into water-efficient landscapes, which saves both time and money in the long term, has high up-front costs that rebates by utilities only partially cover.
From his perspective as Westminster’s senior water resource analyst, Drew Beckwith sees a broad social transformation beginning.
“We are in the midst of seeing this social change in how people view a green lawn along the Front Range of Colorado,” he said.
Beckwith perceives a challenge to prevailing notions. Bright-green lawns require not only regular irrigation in most years, but frequent fertilization. They must be mowed regularly, at least to conform to cultural expectations.
“My customers are saying, ’I don’t want to do that anymore,’ and I don’t think it’s only because of the cost of water,” Beckwith said. “I think there is a new social idea, that a green-grass lawn is not a very responsible thing to do in a water-short and dry area like Colorado.”
Westminster, like dozens of other municipalities along the Front Range, has been paying homeowners to replace thirsty turf. The city shares the costs of landscape transformation with homeowners by providing a rebate on physical turf removal, providing new plants to take its place, or a mix of the two. From 11,000 square feet, when the program began in 2020, the program expanded last year to 107,000 square feet in 191 separate projects. On average, customers paid $560 for each project, and the city paid $650.
“We have taken out 4 acres of turf grass in residential properties in Westminster over the last three years,” Beckwith said. That’s enough water for 20 single-family homes.
In these numbers, Beckwith sees just the earliest stage of a transformation.
“You will have the bleeding edge of folks who pick it up because they are super trend-setters. They were doing this over a decade ago,” he said. “I think we are past the bleeding edge, and we are now into the early adopters. These are normal people who are saying, ’Yeah, this is probably something we should do.’”
Beckwith expects to see, during the next three to five years, many more of the early adopters wanting to replace their turf.
”And then we are going to be in the meat of that general population that is going to start changing their landscapes,” he said. “Beyond will be some people who will never want to change. And that’s OK.”
Nothing to the contrary
By Beckwith’s classification, Don and Jill Brown would be classified as being on the bleeding edge. They live in a red-brick house in Colorado Springs with a large lot. He’s a counselor, of marriages among other things, and she is an author.
In 2017, they decided to do something with a weedy 30-foot-by-80-foot section of their large lot. But instead of Kentucky bluegrass, said Don Brown, they wanted vegetation more natural to Colorado. They chose blue grama.

The grass can go brown in a drought but does not die. “In a dry year, we might water it once or twice. This year, not at all,” he said.
It grows to be about knee-high, but that’s it. Once established, it leaves no room for weeds. He rarely mows.
“We really love it,” he said. “We like the look of it. We like the low maintenance. And we especially like the sense of being responsible stewards of this property.”
A native grass, blue grama evolved in the context of Colorado’s arid environment, the nation’s seventh driest, with an average 18.1 inches of precipitation annually. Colorado Springs gets a little less: 15 to 16 inches.
“In this fairly arid state, we learned that if you use native plants, you will do a lot better,” Don Brown said.
As for the aesthetics, it hasn’t provoked any contrary comments from passersby. “It looks like a meadow,” he said.
Next in the series: The Western Slope delivers 70% of the Colorado River water. So why do Aspen, Vail and Grand Junction, too, want to crimp thirsty turf?

Maybe by now you’ve heard that the collective users of the Colorado River have come together in harmony and agreed to cut water consumption significantly to avoid further depletion of Lakes Powell and Mead. Well it’s true! And the feds even seem ready to sign onto the plan. Maybe you’ve also heard this means the crisis is over and we can all relax and go home now.
I don’t think so.
A refresher: The 1922 Colorado River Compact divvied up the river between the Upper and Lower Basin states (Mexico was added later). They assumed at least 16.5 million acre-feet ran down the river each year, when in fact it was more like 14 million acre-feet. This discrepancy became clear over the last two decades as the water users’ giant savings accounts — Lakes Mead and Powell — were depleted to critically low levels.
The “Natural Flow” is an estimate of how much water would flow past Lees Ferry if there were no diversions or dams upstream. Basically it’s the amount of water available for all of the river’s consumers. Source: USBR
That prompted federal water officials to call on the states to cut consumption by 2 million to 4 million acre-feet per year, or else they would implement the cuts themselves. After a lot of wrangling, the Lower Basin states (Arizona, California, and Nevada) finally relented and proposed 3 million acre-feet of cuts. Perfect, right?
Wrong. Their cuts would be spread out over three years, meaning their reductions only amounted to 1 million acre-feet per year, which is far less than needed. The deal seemed to many of us like a non-starter — or at least like very faulty math.
But it so happens that the proposal came on the heels of an extraordinarily wet winter in the Colorado River Basin, giving a bit of a boost not only to the reservoirs, but also to forecasters’ optimism regarding river flows over the next few years. Also, water users have responded to mandated cuts and done some voluntary cuts of their own, and the wet year meant they had to irrigate less, bringing Lower Basin water consumption to its lowest point in decades.
“New plot using the nClimGrid data, which is a better source than PRISM for long-term trends. Of course, the combined reservoir contents increase from last year, but the increase is less than 2011 and looks puny compared to the ‘hole’ in the reservoirs. The blue Loess lines subtly change. Last year those lines ended pointing downwards. This year they end flat-ish. 2023 temps were still above the 20th century average, although close. Another interesting aspect is that the 20C Mean and 21C Mean lines on the individual plots really don’t change much. Finally, the 2023 Natural Flows are almost exactly equal to 2019. (17.678 maf vs 17.672 maf). For all the hoopla about how this was record-setting year, the fact is that this year was significantly less than 2011 (20.159 maf) and no different than 2019” — Brad Udall
All of that was enough to prompt the feds to include the proposed Lower Basin cuts in an updated environmental impact statement and to make it the preferred alternative. They seem to think it will be enough to fend off the crisis, for now. And maybe it will be. But here are some numbers to consider:
Lake Powell currently holds about 8.7 million acre-feet of water, which is higher than the last two years, but 2.2 million AF less than on this date in 2020.
Lake Mead currently holds about 8.8 million acre-feet, which is less even than in 2021.
Lake Powell, alone, lost 136,550 acre-feet — or about 44.5 billion gallons — to evaporation between July 1 and Nov. 1 of this year.
The combined storage of Lake Meads and Powell is currently at about 17.5 million acre feet, which is less than a third of the total capacity. In other words, the reservoirs are still two-thirds empty — even after the big winter.
Crisis averted? Probably, at least for now. And with an El Niño pattern likely in coming months, we might get another big winter. Still, it seems somewhat imprudent to relax efforts to cut consumption — and to discount more drastic plans for dealing with the diminishing Colorado River.

Click the link to read the article on The Denver Post website (Elise Schmelzer). Here’s an excerpt:
The chances that water levels will fall below critical elevations before 2027 are now 8% at Lake Powell and 4% at Lake Mead, according to the new analysis. Previous estimates, based on September 2022 data and an assumption that nothing would change in the management of the reservoirs, had found a 57% chance of critically low elevations at Lake Powell and 52% at Lake Mead. With the improved forecasts, the federal government appears poised to move forward with a plan by the seven states in the Colorado River Basin to reduce use for the next three years. Earlier this year, federal officials proposed forcibly cutting the amount of water sent downstream to the Lower Basin if the states could not find a compromise on reducing use. On Wednesday, the officials said they had ruled out those forced cuts…
The Bureau of Reclamation now will undertake a more thorough analysis of the states’ plan. The plan, created by the three Lower Basin states — California, Arizona and Nevada — would reduce water use by those states by 3 million acre-feet over the next three years. Most of that reduced use would be achieved through projects paid for by federal money from the Inflation Reduction Act, including conservation projects in Tucson and Phoenix. The four Upper Basin states — Colorado, New Mexico, Wyoming and Utah — signed onto the plan this spring.
Colorado’s top negotiator for the river said in a news release Wednesday that she and her team were reviewing the revised federal analysis and considering whether the analysis can “provide meaningful and enforceable reductions in use to address near-term challenges facing the Colorado River System.”
“If there’s a lesson to be learned from the last few years, it is that we must live within the means of the river if we hope to sustain it,” said Becky Mitchell, the state’s Colorado River commissioner.

WASHINGTON – The Biden-Harris administration today announced next steps in the Administration’s efforts to protect the stability and sustainability of the Colorado River System and strengthen water security in the West. The Department of the Interior’s Bureau of Reclamation released a revised draft Supplemental Environmental Impact Statement (SEIS) as part of the ongoing, collaborative effort to update the current interim operating guidelines for the near-term operation of Glen Canyon and Hoover Dams to address the ongoing drought and impacts from the climate crisis.
In order to protect Glen Canyon and Hoover Dam operations, system integrity, and public health and safety through 2026 – at which point the current interim guidelines expire – an initial draft SEIS was released in April 2023. Following a historic consensus-based proposal secured by the Biden-Harris administration in partnership with states – which committed to measures to conserve at least 3 million-acre-feet (maf) of system water through the end of 2026 enabled by funding from President Biden’s Investing in America agenda – Reclamation temporarily withdrew the draft SEIS to allow for consideration of the new proposal.
Today’s revised draft SEIS includes two key updates: the Lower Basin states’ proposal as an action alternative, as well as improved hydrology and more recent hydrologic data. The release of the revised draft SEIS initiates a 45-day public comment period.
“Throughout the past year, our partners in the seven Basin states have demonstrated leadership and unity of purpose in helping achieve the substantial water conservation necessary to sustain the Colorado River System through 2026,” said Deputy Secretary Tommy Beaudreau, who led negotiations on behalf of the Administration. “Thanks to their efforts and historic funding from President Biden’s Investing in America agenda, we have staved off the immediate possibility of the System’s reservoirs from falling to critically low elevations that would threaten water deliveries and power production.”
“The Colorado River Basin’s reservoirs, including its two largest storage reservoirs Lake Powell and Lake Mead, remain at historically low levels. Today’s advancement protects the system in the near-term while we continue to develop long-term, sustainable plans to combat the climate-driven realities facing the Basin,” said Reclamation Commissioner Camille Calimlim Touton. “As we move forward in this process, supported by historic investments from the President’s Investing in America agenda, we are also working to ensure we have long-term tools and strategies in place to help guide the next era of the Colorado River Basin.”
Key Components of Revised Draft SEIS
Reclamation conducted updated modeling analyses using June 2023 hydrology for the No Action Alternative, Action Alternatives 1 and 2 from the initial draft SEIS, and the Lower Division proposal. The results of that modeling indicate that the risk of reaching critical elevations at Lake Powell and Lake Mead has been reduced substantially. As a result of the commitment to record volumes of conservation in the Basin and recent hydrology, the chance of falling below critical elevations was reduced to eight percent at Lake Powell and four percent at Lake Mead through 2026. However, elevations in these reservoirs remain historically low and conservation measures like those outlined by the Lower Division proposal will still be necessary to ensure continued water delivery to communities and to protect the long-term sustainability of the Colorado River System.
Based on these modeling results, Reclamation will continue the SEIS process with detailed consideration of the No Action Alternative and the Lower Division Proposal. The revised SEIS designates the Lower Division Proposal as the Proposed Action. Alternatives 1 and 2 from the initial SEIS were considered but eliminated from detailed analysis.
Historic Funding from Investing in America Agenda
President Biden’s Investing in America agenda is integral to the efforts to increase near-term water conservation, build long term system efficiency, and prevent the Colorado River System’s reservoirs from falling to critically low elevations that would threaten water deliveries and power production. Because of this funding, conservation efforts have already benefited the system this year.
This includes eight new System Conservation Implementation Agreements in Arizona that will commit water entities in the Tucson and Phoenix metro areas to conserve up to 140,000-acre feet of water in Lake Mead in 2023, and up to 393,000-acre feet through 2025. Reclamation is working with its partners to finalize additional agreements. These agreements are part of the 3 maf of system conservation commitments made by the Lower Basin states, 2.3 maf of which will be compensated through funding from the Inflation Reduction Act, which invests a total of $4.6 billion to address the historic drought across the West.
Through the Bipartisan Infrastructure Law, Reclamation is also investing another $8.3 billion over five years for water infrastructure projects, including water purification and reuse, water storage and conveyance, desalination and dam safety.
To date, the Interior Department has announced the following investments for Colorado River Basin states, which will yield hundreds of thousands of acre-feet of water savings each year once these projects are complete:
$281 million for 21 water recycling projects that are expected to increase annual water capacity by 127,000 acre-feet annually;
$71 million for 32 drought resiliency projects to expand access to water through groundwater storage, rainwater harvesting, aquifer recharge and water treatment;
$50 million over the next five years to improve key water infrastructure and enhance drought-related data collection across the Upper Colorado River Basin; and
The process announced today is separate from the recently announced efforts to protect the Colorado River Basin starting in 2027. The revised draft SEIS released today would inform Reclamation’s ongoing efforts to set interim guidelines through the end of 2026; the post-2026 planning process advanced last week will develop guidelines for when the current interim guidelines expire.

The end of September marked the end of Water Year 2023 (WY2023). This is a good time to take stock of the year’s runoff and to understand how much reservoir storage improved. What kind of a year was WY2023? How long will any added storage last? Can we ease our collective effort to reduce consumptive uses and losses in the basin?
In Summary
The short answer is that WY2023 was certainly a good year for runoff, reservoir inflow, and increases in reservoir storage—but the same amount of inflow would have to occur for several additional years to fully recover storage to what it was in summer 1999 when the system was last full. Such a string of high flow years has not occurred in the 21st century and is unlikely in the future.
History also warns that we should work to conserve the gains of WY2023. In notably wet WY2011, WY2017, and WY2019, extra storage that accumulated during each year’s snowmelt runoff was totally consumed in approximately two years. Thus, our past shows that there is potential to quickly consume the benefits of a good water year. We’ve done it before. It is imperative to keep a keen eye toward accomplishing significant reductions in water use throughout the basin to save what we have gained. We should not expect Mother Nature to bail us out again.
The Details
Estimates of WY2023 unregulated inflow and natural flow indicate that the year’s runoff was the second largest in the 21st century, exceeded only by WY2011. The Colorado Basin River Forecast Center estimates that the April to July unregulated snowmelt inflow to Lake Powell was 10.6 million acre feet (maf) and that the total unregulated inflow for the year was 13.4 maf. Reclamation estimates that natural flow at Lees Ferry in WY2023 was 17.7 maf (Table 1). Unregulated inflow is the estimated stream flow if little of this year’s runoff had been stored in reservoirs upstream from Lake Powell, and natural flow is the estimated flow at Lees Ferry if there were no reservoirs in the basin and no upstream consumptive uses.
Table 1. Natural flow and total basin consumptive use in the five largest runoff years of the 21st century. Total basin consumptive use includes reservoir evaporation and use by Mexico but does not include use in Lower Basin tributaries.
Data concerning reservoir storage are made available by Reclamation at their comprehensive basin-wide hydrologic data base. Daily water storage data are available for 46 reservoirs in the basin including all the large reservoirs and many small ones.
Figure 1 shows how reservoir storage changed during the 21st century. Total storage in all the reservoirs reported in Reclamation’s database is shown in blue, and storage in the three different parts of the watershed are distinguished. Between 60 and 80% of all reservoir storage in the basin occurs in Lake Mead and Lake Powell (orange line). Between 16 and 32% of basin reservoir storage occurs in the many reservoirs upstream from Lake Powell (green line), and between 4 and 8% of basin storage occurs in Lake Mohave and Lake Havasu (red line) that are downstream from Hoover Dam. Graph showing daily storage contents of reservoirs of the Colorado River basin, as reported by Reclamation, between 1 January 1999 and 30 September 2023. Data do not include reservoirs on Lower Basin tributaries.
The most striking trend in these data is that reservoir storage decreased greatly between August 1999 and October 2004 when total storage decreased by 27.4 maf and storage in Lake Mead and Lake Powell decreased by 24.5 maf. There was a small amount of recovery in storage between October 2004 and August 2019; total basin storage increased by 4.1 maf, and storage in Lake Mead and Lake Powell increased by 0.9 maf. Between August 2019 and March 2023, storage plunged again, decreasing by 14.8 maf in the entire watershed of which 11.4 maf was lost from Lake Mead and Lake Powell. These trends were described in more detail by Schmidt, Yackulic, and Kuhn (2023, The Colorado River water crisis: its origins and the future. WIREs Water).
On 30 September 2023, the total storage in the watershed’s reservoirs was 28.4 maf, of which 62% was in Lake Mead and Lake Powell. The storage in all reservoirs upstream from Lake Powell was 8.6 maf and comprised 30% of the total basin storage. Total basin storage in WY2023 peaked on 13 July at 29.7 maf, and the combined storage in Mead and Powell peaked on 16 July at 18.0 maf (Table 2).
How does this year’s increase in storage compare to increases in other years of large inflow? At the beginning of the WY2023 runoff season in mid-March, total reservoir storage in the basin had dwindled to 21.3 maf (Table 2), which is approximately 18 months of supply, based on the average basin-wide water consumption rate for 2016-2020. The combined storage contents of Lake Mead and Lake Powell was 12.7 maf.
Between mid-March and mid-July, total basin-wide storage increased by 8.4 maf, of which 5.3 maf accumulated in Lake Mead and Lake Powell. In comparison, the other four large runoff years of the 21st century — 2005, 2011, 2017, and 2019 – resulted in increases in basin reservoir storage between 5.2 and 8.8 maf and increases in storage in Lake Mead and Lake Powell between 3.7 and 6.9 maf (Table 2). Not only was WY2023 the second largest runoff year of this century, but reservoir storage increase was also the second largest of the century.
Nevertheless, the increase in reservoir storage in WY2023 was small in comparison to the total loss in storage that had occurred since summer 1999. Between August 1999 and March 2023, the reservoir system lost 38.1 maf, and the increase in storage in WY2023 was only 22% of that amount. It would take another 3 to 6 years of very large runoff to fully recover the basin’s reservoirs to what they had been at the turn of the 21st century.
It is unrealistic to expect that the next several years will be similar to the remarkable winter of 2022-2023. No other high flow year of the 21st century was immediately followed by another high flow year. Our best hope for achieving sustainability in water supply is for the Basin States and the federal government to reach new agreements to greatly reduce basin-wide water use so that the modest recovery in reservoir storage in WY2023 might be preserved. Otherwise, our gains may quickly disappear.
Historical data from the previous wet years of this century provide a cautionary tale about how slowly the political process responds to the opportunity provided by a wet winter. Table 3 summarizes the duration of months it took to consume the increased supply of each of the previous years of large runoff. Half of the supply provided by the largest inflow year of WY2011 was gone 11 to 13 months after peak storage had occurred in early August 2011; 8 to 10 months after that, all of WY2011’s large runoff had been consumed (Table 3). The historical story is the same for WY2017 and WY2019.
Since mid-July when the snowmelt season had ended, reservoir storage has begun to decline. The basin’s reservoirs lost 1.3 maf of storage between mid-July and 30 September of which 0.3 maf was lost from Lake Mead and Lake Powell and 0.9 maf from the reservoirs upstream from Lake Powell. The total consumption in these 2.5 months was 16% of the “benefit” of WY2023. Today, the contents of Lake Mead and Lake Powell are about the same as what they were in mid-June 2021.
A Last Thought
One strategy for maintaining a public focus on water conservation would be to widely report—every month—changes in total reservoir storage. The Basin States, and the basin’s citizens, would benefit from knowing the rate at which we are consuming the bounty of the WY2023 supply. It would be especially useful to know the point in time when we consume half of what we gained this year. If we reach that point in less than a year, we would have fair warning that the political process by which we now seek to reduce water consumption is too slow. Hope for a secure and sustainable water supply must rely on nimble and adaptable strategies for reducing water consumption and saving the gains of each wet year.

The newly appointed director of the state water board visited the Colorado River Water Conservation District in Glenwood Springs [October 18, 2023], and their conversation focused on a topic that has long been a concern for the district: temporary, voluntary and compensated water conservation programs.
Lauren Ris, who took over as director of the Colorado Water Conservation Board in August, replaces former CWCB director Becky Mitchell, who is turning her full attention to her position as the Colorado representative to the Upper Colorado River Commission and negotiating on behalf of the state on how to operate the Colorado River system. Ris, a water policy expert, had been deputy director of CWCB since 2017.
At the River District’s quarterly meeting, held Wednesday, Ris talked with board members about two water conservation programs, both of which have long been contentious and critical issues for the district. In 2018, the CWCB adopted a policy statement about demand management that said it would aim to avoid disproportionate negative economic or environmental impacts to any single sub-basin or region in Colorado. Ris assured the River District that was still the case.
“I don’t think anything has changed about our board’s position on that,” Ris said. “That has been our mantra all along.”
At the heart of a demand-management program would be paying Western Slope irrigators on a temporary and voluntary basis to use less water in an effort to boost Lake Powell’s levels, which have fallen to historic lows as a result of overuse, drought and climate change. The participation of Western Slope agriculture is key to creating a workable program, but the River District has said propping up the Colorado River system cannot come solely at the expense of its constituents; impacts must be spread equitably across the state.
The mission of the River District, which is based in Glenwood Springs and spans 15 counties in western Colorado, is to lead in the protection, conservation, use and development of Western Slope water. Paying water users to irrigate less has long been controversial on the Western Slope, with fears that these temporary and voluntary programs could lead to a permanent “buy and dry” situation that would negatively impact rural farming and ranching communities. With roughly 86% of the state’s water use in agriculture, irrigators often say they “have a target on their back” when it comes to finding places to cut water use.
In 2019, the state of Colorado undertook a two-year investigation into the feasibility of a demand-management program, convening nine workgroups, but the investigation has been tabled, and so far, the state has not created a program. The River District also conducted its own parallel study of demand management.
“I think it’s still a question out there whether it makes sense for the state at this time with what we have available to us right now and the information we have, given everything that’s going on at the federal level, if it makes sense to pursue that,” Ris said.

Board members had questions and concerns about two water conservation programs that could impact the West Slope.

System conservation
Although a state demand-management program may not be on the immediate horizon, another upper basin water conservation program — which is conceptually similar — will take place for a second year, in 2024: system conservation. Administered by the Upper Colorado River Commission and funded by the federal Inflation Reduction Act, system conservation pays water users in Colorado, Wyoming, Utah and New Mexico to cut their water use, typically by drying up fields, for one season.
The River District had sought to have a say in the project approval process, going so far as developing its own criteria for projects within its boundaries. But in March, water managers said that the UCRC had sole authority over the program and that the River District could not be involved in approving 2023 projects after all.
A recent study makes the case for River District involvement and points out what many already know: Water users in the Colorado River basin have a preference for local approaches to water conservation and do not trust formal programs run by state or federal officials — such as the UCRC. But despite this evidence, there probably won’t be an oversight role for the River District in system conservation again in 2024.
“Is there a role for the conservation districts to help them in that process of looking at applications?,” River District board president and Eagle County representative Kathy Chandler-Henry asked Ris. “We feel like we’re one level closer to the users on the ground and able to support that process.”
Ris replied that system conservation is being run by UCRC and that even the CWCB’s role is fairly limited.
Greg Felt, CWCB chair and representative from the Arkansas River basin, accompanied Ris at the River District meeting. The CWCB will consider whether to approve system conservation again for 2024 at its November meeting. He said he does not like the idea of paying people not to farm, but the 2024 program will have a narrower scope that explores demand-management concepts and supports innovation and local drought resiliency on a longer-term basis.
“What we were presented with was an additional layer, which was to prioritize projects that either helped enhance drought resiliency or conservation,” Felt said. “All of a sudden, I saw a value there that I hadn’t seen before. … I can get behind this because I think it will really help agriculture.”
Ris said that, going forward, the process would have more transparency, echoing a promise made by Mitchell.
For the 2023 program, the UCRC released few details about the individual projects. Payment amounts, the exact location of projects, names of participating ditches and information about water rights, including priority dates and decreed amounts of water, were redacted in the publicly available contracts between irrigators and the UCRC.
“We’re committed to making some changes based on the feedback that we heard,” Ris said. “We are planning on making as much information as possible available to interested parties. … We will still redact personal identifying information but are going to try and go light on the black pen.”
River District General Manager Andy Mueller said transparency for SCP 2024 was imperative, but he also pushed for a process to protect the district’s water users.
“I know (demand management and system conservation) are two different programs, but they may potentially have the same effect inside of our state, and that is reducing consumptive use and potential injury,” Mueller said. “We’d love to work with you to continue to improve both protections on injury and how we address proportionality. We think those are really important to our water users. This board has voiced great concern.”
Ris said the CWCB shares that concern and that the two agencies should continue to talk about it as they go forward.
A record-breaking winter snowpack last year halted a precipitous downward spiral on the river and raised water levels at the nation’s two largest reservoirs, Lakes Mead and Powell. But something else is also at play this year – farmers, cities and Native tribes are simply using less. Arizona, California and Nevada’s usage of Colorado River water has hit new lows, state officials and US Bureau of Reclamation Commissioner Camille Calimlim Touton told CNN in an interview.
“The record conservation is already seeing its impact within the reservoirs,” Touton said. “It’s easy to see our success within the levels of the reservoirs we manage.” Lake Powell has risen 52 feet since hitting a low point in February of this year, while Mead has risen nearly 23 feet since November…
Part of the reason is last winter’s blockbuster precipitation, which helped replenish levels in reservoirs across the West. In California, southern cities like Los Angeles that are normally more dependent on Colorado River water have been able to pull more from its own refilled reservoirs like Lake Oroville…
[Bill] Hasencamp told CNN the three lower-basin states have only used 5.8 million acre-feet this year of the 7.5 million acre-feet they are allotted annually.
“We’re pretty much at a sustainable level,” Hasencamp said. “It really gives hope for the future. Despite it being a wet winter, we’re going to do everything we can to reduce use and work with the feds.”

Editor’s note: Today (Oct. 11, 2023) is the 75th anniversary of the signing of the Upper Colorado River Basin Compact. The following is an excerpt from Revisiting the Upper Colorado River Basin Compact on its Diamond Anniversary, a forthcoming analysis by Eric Kuhn and John Fleck, co-authors of the book Science Be Dammed: How Ignoring Inconvenient Science Drained the Colorado River.
BY ERIC KUHN AND JOHN FLECK
The Upper Colorado River Basin Compact was signed by representatives from Arizona, Colorado, New Mexico, Utah, and Wyoming on October 11, 1948, after over two years of negotiations. It was an attempt to resolve the allocation of water among the five states, and for three quarters of a century it performed that task well.
But as we approach the middle of the third decade of the 21st century, the challenges of overallocation of Colorado River, over-appropriation of the water we have, and climate change reducing the river’s flows, the Upper Basin Compact and the extended body of rules in which it is embedded are showing their age.
At its simplest, the Upper Basin Compact divided the water use available from the 7.5 million acre-feet per year apportioned to the Upper Basin by the 1922 Colorado River Compact. The compact accomplished two major tasks:
It apportioned the consumptive use of water among the Upper Basin states using percentage allocations. Colorado received 51.75%, New Mexico 11.25%, Utah 23%, and Wyoming 14% of the water available for use in the Upper Basin. Arizona received a fixed 50,000 acre-feet per year.
It defined the obligations of the Upper Division states (Colorado, New Mexico, Utah, and Wyoming) to deliver water to the Lower Basin at Lee Ferry to satisfy the requirements of the Colorado River Compact.
In pursuing a new set of post-2026 Colorado River Operating rules, major water agencies and state leaders have insisted that the “Law of the River” – the suite of rules dating to the 1922 Colorado River Compact and including the Upper Basin Compact – should be a fundamental guiding principle of future river management. “The Post-2026 Operations should reside in a framework consistent with a reasonable interpretation of the Law of the River,” the Central Arizona Project wrote, to cite one example among many.[1] But a careful review of the history of the Upper Basin Compact shows how tenuous a foundation the Law of the River provides, and how uncertain any attempt at “reasonable interpretation” might be, because of fundamental uncertainties about what the Law actually says.
When the Upper Basin compact was signed there was agreement on the definition of the “what” to which the percentage allocations apply. Water use in the Upper Basin was limited by water availability after meeting the Colorado River Compact’s Lee Ferry delivery requirements. Today, because of the impacts of climate change on flows, there is no such agreement and there are claims that the intent of the compact was to provide an equal amount of water for use to each basin. This creates deep uncertainty in the actual volumes of water available to each state.
There is still no consensus on how to measure consumptive use basin-wide. The Upper and Lower Basins use different methods, and Lower Basin tributary use is neither well understood nor quantified. This makes managing the river system challenging.
The Upper Division States claim overuse by the Lower Basin based by using one measurement method, while using a different method for their own uses. There is valid dispute over these theories and methodologies.
Tribal water rights remain unresolved and limited in some cases by provisions aimed at preventing tribes from using their full legal entitlements.

In negotiating the Upper Basin Compact, the states made key decisions on critical compact issues that continue to echo through 21st century water management.
STREAM DEPLETION
Colorado River management has always suffered under controversy and ambiguity around the question of how to measure consumptive use. The Colorado River Compact did not include a definition of “beneficial consumptive use.” In the century since it was signed, two competing (and conflicting) methods have been used: diversions less return flow, and stream depletion. On some scales, they may look the same. But on large enough scales, they do not, in ways that have profound implications for 21st century river management decisions.
Under the stream depletion theory, each basin’s consumptive use is measured as the net reduction in natural flows caused by man-made activities. For example, the Upper Basin’s consumptive use would be calculated as the amount that upstream uses deplete the natural flow of the river at Lee Ferry.
During the Upper Basin Compact negotiations, Colorado and Arizona were the main proponents of this theory. It was ultimately adopted in Article VI of the Upper Basin compact as the method for measuring consumptive use.
But the stream depletion theory is not universally used in river management today. It is, for example, used to quantify reservoir evaporation in the Upper Basin, but not the Lower Basin. It is not used to measure Lower Basin mainstream uses, where the “diversions minus return flows” method is used instead. Uses on the Lower Basin tributaries, which are included in the compact definition of “Colorado River System” are currently not measured at all – using either theory.
ALLOCATING STATE WATER BY PERCENTAGES RATHER THAN ABSOLUTE AMOUNT
The Upper Basin Compact is frequently praised for state-by-state allocations based on percentages (except Arizona), rather than absolute numbers, thus avoiding the mistake in the Colorado River Compact that over-allocated the river’s water.
But modern policy discussions are unsettled on a central issue – percentage of what? On their own, the percentages are meaningless without reference to some sort of underlying total amount of water available to be shared among the states.
When negotiating the Upper Basin Compact, the states’ representatives were clear on what they intended as the basis for using the percentages. They intended to apply the percentages to the amount of water available for consumptive use in the Upper Basin after meeting what they viewed as their compact “delivery obligations” at Lee Ferry.

Today, there is no such consensus. Climate change has altered the river’s hydrology, putting the burden of impacts on the Upper Basin. Its leaders have responded by arguing that the compact’s negotiator’s intention was to equally divide the water available to each basin for use. Since climate change is causing a decline in natural flows, whatever Lee Ferry obligations the Upper Division States have must now be adjusted to reflect the new hydrologic reality.
Resolving this issue requires either litigation, negotiated settlement, or collectively agreeing on a modified approach – one that appropriately factors in climate change and maintains the benefits of the 1948 flexible percentage allocations.
TRIBAL WATER
While large Native American water needs and legal entitlements were identified before the Upper Basin Compact was negotiated, Tribal communities were excluded from the negotiations. Instead, Indian water use, which the negotiators knew was legally perfected long before 1922, was lumped into state allocations, with each state being responsible for meeting tribal needs from its share of the water. This gamble set up a potential conflict between the apportionments made by the Upper Basin Compact and the protections provided Indian rights under the Colorado River Compact.
A decade after the compact was signed, this conflict became real. In response, Upper Basin leaders took steps to limit tribal water rights and prevent full use of tribal entitlements, by inserting provisions in project authorizing legislation. The implications today are a legacy of intentional discrimination against tribes, unresolved legal questions around tribal water rights, and provisions that treat Native Americans as second-class citizens.

Ranchers and farmers across the Colorado River Basin, who control roughly 80% of the drought-strapped river’s flows, are reluctant to sign up for voluntary, government-funded water conservation programs for a variety of reasons identified in a new report.
Chief among them are a fear of losing their water rights, seeing their water use reduced, and engaging with far-off bureaucracies that they believe aren’t qualified to help.
“Agricultural Water Users’ Preferences for Addressing Water Shortages in the Colorado River Basin” is a study conducted by the Western Lands Alliance (WLA) in partnership with the Ruckelshaus Institute at the University of Wyoming in Laramie. Released late last month, it includes survey responses from more than 1,000 ranchers and farmers in six Colorado River Basin states, as well as interviews with producers. The WLA represents landowners and agricultural producers across the West.
The WLA launched the research effort to better understand how agricultural water users in the region view different water conservation efforts and what it would take to convince them to participate. Hallie Mahowald, a co-author of the report and chief programs officer at the WLA, said in a webinar in September that the landowners will be key to finding solutions to the growing shortages on the river because they control so much of its water.
“We feel it is critical to understand landowner perspective and to solicit landowner input if we are going to develop successful strategies to address Western water shortages,” she said.

The report comes as the river basin remains mired in a long-running drought that has come close to crippling lakes Powell and Mead and experiences ongoing shortages as climate change continues to sap its flows.
At the same time, hundreds of millions of dollars in federal funding is being made available to help the Colorado River Basin states better manage the river, reduce water use, and develop programs to sustain the basin’s cities and farms as the region continues to warm.
Drew Bennett, MacMillan Professor of Practice in Private Lands Stewardship at the University of Wyoming in Laramie, said the survey results show a disconnect between ranchers and farmers and the agencies who are charged with overseeing Colorado River Basin water management. In fact, more than 85% of those surveyed said they did not trust the water agencies that help manage the giant river system.
“We need to build additional trust…it will be absolutely critical moving forward,” Bennett said.
And while more than 50% of those surveyed are engaging in at least limited conservation practices, they are not interested in doing more if their water rights aren’t strongly protected, if they are not adequately compensated, and if the programs aren’t administered locally.
This lack of trust, the report says, “may create a barrier to gaining buy-in for new water management strategies, even if they are supported by significant funding from state and federal government agencies.”
The river basin spans seven states. The Upper Basin includes Colorado, New Mexico, Utah and Wyoming, and the Lower Basin includes Arizona, California and Nevada.
Researchers broke out survey responses based on which basin a grower operates in. Key findings of the report include:
97% of Upper Basin growers (Colorado, New Mexico, Wyoming and Utah) and 96% of Lower Basin growers (Arizona, California and Nevada) are worried about coming shortage-related changes in water policy and new constraints on their water use.
Just 14% of Upper Basin growers and 13% of Lower Basin growers believe that existing water policies and management practices are adequate to address coming shortages.
69% of Upper Basin and 74% of Lower Basin growers have implemented at least one water conservation practice, largely in response to local water shortages.
56% of growers in both basins would engage in programs to improve their water delivery systems if funding is provided.
Just 8% of Upper Basin and 18% of Lower Basin growers would participate in programs that would fallow, or cease production, on the same field for multiple years.
And just 13% of Upper Basin and 14% of Lower Basin growers said there was a high level of trust between water users and water management agencies.
In Colorado, the Colorado Ag Water Alliance has been working to help producers use water more efficiently to prepare for future droughts and manage with less water. But CAWA’s Executive Director Greg Peterson said it’s a difficult task.
“Our goal is to help these people survive. People [who don’t farm] don’t actually understand that there are few opportunities to reduce water use in an agricultural setting,” Peterson said. “You might be able to reduce water use by 5% or maybe 10% without reducing yields. But it’s not easy to do.”
Wyoming and other basin states have begun installing sophisticated new technologies that help determine how much water crops consume, known as consumptive use, and how much water runs off and returns to the river or natural environment after a field has been irrigated. This is a critical measurement because it is only the consumptive use portion of irrigation water that can be administratively “saved” as water left in the river system.
Jeff Cowley is administrator for interstate streams in the Wyoming State Engineer’s Office, the top water regulator in the state. Cowley is implementing new conservation technologies and working with growers who are already participating in one of the new federal programs known as the System Conservation Pilot Program.
Homing in on how much water is saved and left in the river is a complicated question whose answer differs from field to field and crop to crop. When water was plentiful, before the drought and climate change, there was enough water that this kind of precision wasn’t required. But that is no longer the case.
Cowley said this new level of precision is another critical factor in working with skeptical farmers and ranchers because it provides some certainty on what impact programs could have on their water supplies.
“Folks are attached to their water,” Cowley said. “They are willing to try new things, but not on their own dime.”
And any given year, he said, “there is not a lot of room for mistakes.”

Executive Summary The Colorado River Basin is in crisis. There is no longer enough water for all of those who depend on it. The agricultural sector is the largest water user in the Colorado River Basin, meaning that farmers and ranchers are central to both the impacts of and solutions to water shortages. Their involvement will be key to developing effective policy solutions to today’s water crisis.
We surveyed 1,020 agricultural water users throughout six states in the Colorado River Basin to understand their perspectives on the present crisis, their current water conservation practices, and their preferences for strategies to address water shortages going forward. Agricultural water users were primarily concerned about how the current situation could impact water policy, constrain irrigators’ own water use, and constrain other agricultural water users. We also conducted qualitative research to capture preferences for local approaches to managing water and provide additional context on dynamics in the Colorado River Basin, including interviews with 12 agricultural producers and water experts and a focus group with 10 agricultural water users in Colorado.
Perhaps unsurprisingly, we found agricultural water users are already responding to water shortages. Roughly 70% of surveyed agricultural water users have already adopted one or more water conservation practices or adaptation strategies. Importantly, many would consider adopting additional practices. Despite this, few respondents participated in or were aware of formal programs to support water conservation. One exception, however, was the Natural Resources Conservation Service’s Environmental Quality Incentives Program (EQIP). A third of respondents currently or previously participated in EQIP and an additional 37% were aware of the program. Information gathered from interviews and the focus group identified multiple burdens to participation in EQIP and similar programs, and several participants thought the benefits were not worth the effort. These insights suggest an opportunity for revisiting how formal programs meant to incentivize water conservation connect with water users.
Most survey respondents were unlikely to adopt water conservation practices as part of formal demand management or system conservation programs to address water shortages. Only one of eight practices included in the survey – enhancing water delivery systems – had a majority of respondents state that they were likely to adopt the practice. The remaining seven practices had a considerably lower likelihood of adoption. Respondents were also generally opposed to water transfers as a solution to shortages. Opposition was strongest to permanent transfers broadly, as well as to temporary transfers from agricultural to non-agricultural uses. Only temporary transfers from agricultural water users to other agricultural water users had less than 50% opposition. Major barriers to supporting water transfers included concerns about losing water rights, even in temporary transfer arrangements, as well as insufficient financial compensation. Addressing these concerns will be critical to increase participation of agricultural water users in demand management or system conservation. Still, although support for temporary water transfers and demand management practices was low, even equivalently low participation (e.g., 10% to 20%) could help address water shortages as part of a portfolio of strategies for the Colorado River Basin.
We also documented an overwhelming preference for local approaches to managing water shortages and a trust gap with non-local agencies. This was evidenced by respondents’ preference for the local management of formal programs, such as some of the demand management and system conservation programs under consideration, as well as for the administration of funding for water conservation and other programs. Qualitative research participants communicated that strategies to address water shortages must account for the diversity of local contexts across the Colorado River Basin. These strategies could therefore be best implemented at the local level through existing delivery infrastructure and by managers with track records of success. State and federal water managers and agencies involved in program delivery should emphasize building trust with agricultural water users and gaining knowledge about unique features of local contexts. Simply providing additional funding for formal water conservation programs may be inadequate to meet the diversity of challenges across an area of 246,000 square miles. Developing opportunities for dialogue and listening can help foster relationships and improve trust among key stakeholders.
Given the importance of agriculture as the primary water user in the Colorado River Basin, proactively engaging agricultural communities will be critical to successfully managing water shortages. Understanding the perspectives and preferences of agricultural water users, as documented in this report, can help guide the development of solutions that work for producers and other users in the Basin.

Denver Parks and Recreation is replacing the Kentucky bluegrass in four medians along Quebec Street in Denver and turning it into a prairie grass meadow. The project will save millions of gallons of water every year. Denver Water and the Colorado Water Conservation Board are helping fund the project. Learn about the project in this video
It’s not often that a median in the middle of a street gets a lot of attention, and that makes it a perfect candidate for a landscape makeover.
For decades, the four medians separating the north and southbound lanes of Quebec Street, just south of Interstate 70 between Smith Road and Martin Luther King Jr. Boulevard, have featured 10 acres of thirsty Kentucky bluegrass.
Now, the Denver Parks and Recreation department is transforming the grass fields into prairie grass meadows that will be home to a more appropriate type of ColoradoScape that needs significantly less water to thrive.
“The medians had what we call ‘nonfunctional grass,’ which means the grass was not being used for any type of activity. That made it a perfect location for landscape transformation,” said Ian Schillinger-Brokaw, a Denver Parks and Recreation urban ecology planner.
“We were using around 9 million gallons of water every year to keep grass green that no one used, so it was really not a good use of water.”
Sprinklers irrigate the old, water-intensive Kentucky bluegrass fields before the project in June 2023. The bluegrass on the Quebec Street medians required additional irrigation to stay green during the summer. Photo credit: Denver Water.
The landscape transformation project on the four medians is being done in partnership with Denver Water, which is helping to fund the work.
During summer 2023, the city shut off the sprinklers and let the bluegrass die. Then in September, landscape crews from Western States Reclamation planted more than 60 species of prairie grasses and wildflower seeds through the remains of the dead bluegrass.
After the seeds were in the ground, workers sprayed the field with “hydromulch,” which is the process of spraying water mixed with small particles of wood fiber on top of the seeds, so they don’t blow away or get eaten by birds.
The field will be watered over the next two to three years to help the seeds grow. Depending on the weather, some grasses will sprout this fall, while others will begin to grow next spring and summer.
It will take roughly three years for the new plants to become established.

“The field will have a variety of grasses with different heights, colors and textures and the wildflowers will provide an added boost of color,” Schillinger-Brokaw said.
The wide variety of plants will help the new prairie meadows thrive in different weather conditions. For example, some grasses and flowers will do better in dry years, while others will grow better in wet years.

“By adding a variety of grass species, we’re ensuring that each season the field will have plants that are in good shape,” he said.
“The field will look very similar to some of our other parks and open spaces in the area, such as Westerly Creek and Prairie Meadows parks.”
Schillinger-Brokaw said the landscape will keep safety in mind by making sure plants around the corners of the medians will be shorter, so they won’t impact drivers’ ability to see other cars and make safe turns at the intersections.

Water savings
Before the landscape conversion, the field required roughly 9 million gallons of extra water every year to keep the Kentucky bluegrass green. By transitioning to a prairie meadow, the goal is to eventually stop watering the field and let Mother Nature provide all the moisture the plants need to survive, Shillinger-Brokaw explained.
The Denver Parks and Recreation department will continue to water the trees on the medians. However, by eliminating the extra irrigation that the bluegrass needed, the overall water use for the medians could be reduced by roughly 8.5 million gallons each year once the plants are established.

“Kentucky bluegrass has been used as the default form of landscaping for decades across many parts of Colorado, but it requires a lot of water,” said Austin Krcmarik, a water efficiency planner at Denver Water.
“With water being such a scarce resource across the West, it’s great to see Denver Parks and Recreation switching to landscaping that fits our climate.”
Additional benefits
The new medians full of prairie grasses and wildflowers are an example of ColoradoScaping, which is landscaping that features low-water-use plants that thrive in our state’s semi-arid climate.
Along with water savings, ColoradoScaping provides additional benefits for Denver’s parks, such as:
Providing more resilient landscapes that can cope with extreme weather, such as drought.
Adding biodiversity to the city with new habitats for pollinators such as birds and bees.
Establishing areas that improve stormwater drainage and improve water quality.
Eliminating the need for mowing the medians regularly throughout the summer.
Saving money on water bills that can be used for other park improvements. (The water savings on the Quebec Street project will save Denver Parks and Recreation roughly $20,000 each year.)

Saving water across the West
Water-saving projects like the Quebec Street median turf conversion are critical because Denver Water gets half of its water supply from the Colorado River Basin, which has seen drought conditions over much of the last 23 years.
“Denver Water and other utilities across the West are actively promoting and working with cities and park districts to look for areas of nonfunctional Kentucky bluegrass and see if other types of landscaping is a better fit to help save water,” Krcmarik said.
It’s In Denver’s Nature
The transformation of the Quebec Street medians is an example of Denver Parks and Recreation implementing the Game Plan for a Healthy City.
The comprehensive plan serves as a roadmap to the future of Denver’s park system. A key aspect is investing in the fight against climate change through conserving water, transforming landscapes, growing the urban canopy and protecting habitats.
A mix of seeds from more than 60 kinds of flowers and grasses will ensure that the medians, once a bland, expanse of water-intensive Kentucky bluegrass, will be home to a wide variety of prairie grasses and wildflowers sporting different textures and colors. Photo credit: Denver Water.
As part of the plan, in April 2023, Denver Parks and Recreation changed its policy of using thirsty turfgrass, like Kentucky bluegrass, as its primary landscaping groundcover in areas with no recreational value. The Quebec Street medians are an example of how the city is using drought-tolerant and ecosystem-friendly plants instead of turfgrass.
“We’re doing a lot across the city to reduce our water footprint and the Quebec Street medians project is one of the biggest landscape transformation projects we’ve done,” Shillinger-Brokaw said.
“We ask for patience as these new grasses grow, and we’re excited to see the new look coming soon to this part of the city.”

Local ranchers are hoping a soil health experiment will reveal clues about how they can better manage their land under dry conditions as the Colorado River basin continues to struggle under the effects of climate change and historic drought.
Four sites are participating in the project, which is being administered by the Roaring Fork Conservancy. Each of the participating grass and alfalfa fields will have six test plots: Two are controls that get no special soil treatments; two will be mechanically aerated, which involves perforating the soil with small holes so that plant roots can better receive water and nutrients; and two will receive aeration plus a layer of carbon-rich organic matter known as biochar.
Then, one plot from each treatment category will receive a normal amount of irrigation water and the other three will be watered only in the beginning of the irrigation season to mimic drought conditions.
The goal is to see if the soil treatments can maintain crop yield even when fields receive less water. Scientists and engineers from the conservancy and Carbondale-based engineering firm Lotic Hydrological took grass and soil baseline samples this season and will do so again next season after the treatments and compare them. If the soil treatment techniques work and are able to be scaled up, they could be part of the solution for drought-stressed crops and ranchers throughout the state.
Carbondale’s Turnabout Ranch, which gets its water from Prince Creek via the Mount Sopris Ditch, is participating in the project. Owner Brendan Doran, a ski pro at Aspen Skiing Co., says that bad snowpack conditions carry over from the winter.
“Being in skiing in the wintertime and having hard snow years, we have the same thing in agriculture,” he said. “And there’s a way to prepare ourselves for it. … Moving forward, we can have a better idea of how to manage things and keep the yield the same.”
Mike Spayd — another skier-turned-first-generation-rancher who works at Aspen Highlands — is participating in the project on ground he leases near his home in Missouri Heights. Junior water rights from the Spring Park Reservoir and Mountain Meadow Ditch irrigate the 90 acres of grass and alfalfa that gets a single cutting a year.
“We are dependent on a good runoff every year to fill that water right, and drought resiliency is an important part of farming no matter what your water rights are,” Spayd said. “Being able to make the most out of any water we have and develop drought resiliency is pretty important to me.”
Doran and Spayd use sprinkler systems to irrigate and say they want to improve the soil health of their land. The other two projects are on a Pitkin County-owned, 36-acre parcel in Emma known as the Shippee Open Space and a ranch near Basalt.

More state funding scales up program
Conservancy staff are overseeing the project, which is one of 31 drought-resiliency projects across the state under the umbrella of the Colorado Ag Water Alliance (CAWA) and partially funded with a grant from the Colorado Water Conservation Board (CWCB). In addition to soil health, other projects around the state focus on growing more drought-resistant forage crops, irrigation efficiency and livestock.
The CWCB granted $183,700 in funding for the initial statewide program in 2022. The Pitkin County soil treatments project received $18,862, plus additional funding from The Nature Conservancy and Atlantic Aviation. The state grant money is funneled through CAWA to the conservancy and other local entities around the state that carry out the projects.
The Roaring Fork Conservancy is a Basalt-based nonprofit that focuses on watershed science and education programs, policy, stream management and restoration. Heather Lewin, conservancy director of watershed science and policy, said water is inextricably tied to agriculture — and that’s why the conservancy decided to do this project.
“We think agriculture brings value to our community,” she said. “There’s local food production, economic value, open space, wildlife passage, migration corridors, stewardship. … As you look at the future with less water available, are there ways for a water organization like ours to partner with people on the ground to see if agriculture can stay productive and continue to provide the benefits to the community.”
CAWA is expanding the drought-resiliency projects for next year and is accepting applications for the 2024 season. In September, the CWCB awarded nearly $1 million in funding to scale up the program. CAWA Executive Director Greg Peterson said next year’s program funding is also coming from Front Range water providers Denver Water, Aurora Water, Northern Water, Colorado Springs Utilities and the Walton Family Foundation.
The program is intended for projects that are small, innovative and unproven. Projects that can be scaled up and could have relevant findings for a lot of agricultural producers will be given top priority, Peterson said.
“There’s a lot of need to experiment and try out new ideas,” Peterson said. “You have to be able to make sure it’s not as risky financially for a farmer or rancher to try one of these projects.”
Doran and his wife, Sarah Willeman Doran, bought the Turnabout Ranch (formerly the Tybar Ranch) in 2021. The land needs a lot of love, he said, after years of drought and cattle grazing. His family’s vision for the 450 acres doesn’t include herds of cows, but they do plan on an equestrian facility for healing work with horses, in addition to growing hay.
“Once we get the test results back, we will be able to take the fields and make them more productive, more sustainable,” Doran said. “I think we’re just excited to participate and keep evolving the way that our environment is evolving.”

Colorado River officials plan to expand a conservation program next year that pays farmers and ranchers to use less water. But questions remain about some of the proposed ideas and the program’s overall efficacy.
The state initially launched the System Conservation Pilot Program in 2015 as a part of a multistate effort to conserve water from the Colorado River, which provides water for millions of residents throughout seven states as well as Mexico. The effort was designed to see if conservation efforts could stabilize the water levels in critical reservoirs along the river, like Lake Powell.
While there have been some challenges, the project is set to expand in 2024, Colorado Water Conservation Board Director Lauren Ris said during the National Community Reinvestment Coalition’s Just Economy conference in Denver on Sept. 27.
Some of the changes the CWCB is planning to implement include making it easier for farmers and ranchers to apply for the federally-funded program, creating a transparent pricing mechanism, and encouraging participants to recommend new technology solutions.
These new efforts could help preserve water resources for about 40 million people across multiple states in the Southwest as they face population increases and the need to build more housing. And Colorado is in a unique position to drive that change because of its status as a headwater state, Ris said.
“We really rely on water from mother nature. We don’t have the ability to draw water from somewhere else,” she added.
An unparalleled challenge
When the conservation pilot program began in 2015, concerns about the Colorado River’s declining water levels, largely due to human-caused climate change, were already well established. More than a decade of declining snowfall in the Rocky Mountains created record low water levels in Lake Powell and Lake Mead, which are two of the nation’s largest reservoirs. They also provide water and hydroelectric power to millions of Americans.
To address the issue, Colorado spent about $8.5 million to conserve 47,200 acre-feet of water between 2015 and 2018, according to data shared about the pilot program during the CWCB’s board meeting on Sept. 21. That’s roughly $180 per acre-foot. One acre-foot can support up to two households for a year.
But then the program went dark until 2022 when water levels in the Colorado River reached historic lows. The federal government initially asked several Western states including Colorado to reduce their water consumption by up to 4 million acre-feet per year before deciding to allow the states to work out their own agreement.

By June 2022, the four … Upper Basin states — Colorado, New Mexico, Utah and Wyoming—had put together a five-point water conservation plan. The first point of the plan was to restart the SCPP.
In December, the federal government reauthorized the program and allocated up to $125 million from the Inflation Reduction Act for the Upper Basin states to spend on water conservation efforts between 2023 and 2026.
As of this month, the SCPP has supported 64 projects across the Upper Basin states and conserved about 38,000 acre-feet of water, Amy Ostidek, the water conservation board’s interstate, federal, and water section chief, said during the Sept. 21 meeting. Twenty-two of those projects were in Colorado and they conserved a total of roughly 2,500 acre-feet of water.
Conserving the future
But the program’s re-launch wasn’t as smooth as many had hoped, Ostidek lamented.
“Getting things kicked-off in December just wasn’t tenable for water users trying to make decisions about their operations,” Ostidek said. “And, frankly, that put all of us in a crunch to do things very quickly, and maybe not as well as they could have been done if we had more time.”
To address these issues, the SCPP will open applications for the 2024 program starting in October. Ris said this will help provide some “operational certainty” for water users.
Another aspect that will be revised is the pricing mechanism. This year’s SCPP is paying ranchers and farmers about $150 per acre-foot of water saved, which was based on the median payments allocated under the pilot program, The Colorado Sun reported. However, ranchers and farmers have been getting paid nearly $394 per acre-foot on average.
The program is also looking to incorporate more technology to address data and efficiency gaps in the system. Some target areas include creating drought-resilience tools and implementing conservation strategies that address the needs of rural communities along the lower Colorado River Basin, like in northern Arizona.
“At the end of the day, the people who are most impacted by these decisions are often the most vulnerable members of our communities and the most underserved,” Central Arizona Water Conservation Board member Ylenia Aguilar said.

Water commissioners from Colorado, Utah, New Mexico, Wyoming are focusing on water demand management in the future of a conservation pilot program. The Upper Colorado River Commission met for a special meeting on Sept. 21 and heard an update regarding the System Conservation Pilot Program (SCPP)…Ultimately, the water commissioners unanimously voted to support narrowing the program in 2024 to focus on water demand management and tools for innovation and local drought resiliency. There was also emphasis during the meeting on improving upon what was learned in 2023…
Collum reviewed three options the commission had on the table for 2024. The first option was to have no program in 2024, but no commissioners spoke in favor of that option. The second option was to maximize water conservation.
Option three, unanimously favored by the commissioners, was presented during the meeting as: “Narrow the 2024 SCPP to explore Demand Management (DM) Studies and Support Innovation & Local Resiliency – implement recommended SCPP improvements AND narrow project criteria towards remaining DM questions and supporting innovation & local resiliency resulting in water conservation.”

“…I think when we specifically look at the change in hydrology (and) the definite need for the cuts to happen where the cuts are needed in the lower basin,” Mitchell said. “I really want to think about resiliency on the home front and the thing that we do being focused on building security for our own states and our own water users. And so I think when we look at the implementation with the recommended improvements and the narrow project criteria that are focused on supporting innovation and local resiliency that results in water conservation.” — Becky Mitchell

From email from the Colorado Water Conservation Board (Katie Weeman):
September 21, 2023 (Denver, CO) – the Upper Colorado River Commissioners voted to implement the System Conservation Pilot Program (SCPP) for the 2024 Water Year. SCPP provides Upper Basin water users with the opportunity to participate in temporary, voluntary, and compensated water conservation. SCPP simultaneously allows the Upper Colorado River Commission (UCRC) and Upper Division States to learn from the piloted conservation efforts, expanding knowledge on aspects like monitoring, measurement, and local benefits or impacts. For water users, it provides opportunities to develop tools to build resilience and adapt to long-term drought.
The revamped SCPP integrates input from Upper Basin water users. Changes include:
An earlier application window, beginning in October 2023, to provide operational certainty for applicants.
A transparent pricing mechanism to provide clarity to applicants.
Increased education and outreach to ensure water users are fully informed.
Expanded information about project applications in Colorado with the opportunity to provide comment.
Prioritization of projects that support innovative water conservation and development of drought resiliency tools.
“We learned a lot about SCPP last year, so this year’s revamp integrates a lot of input from Colorado water users,” said Becky Mitchell, Colorado River Commissioner for the State of Colorado. “SCPP should—and can—work in a way that makes sense for Colorado. The pilot program can provide flexibility for Coloradans who want or need to explore innovative conservation projects. As we continue to learn together and do what we can to be part of the solution, I continue to push for reductions where it matters most: in the Lower Division States.”
“There is no silver bullet for drought resiliency in Colorado,” said Lauren Ris, Director of the Colorado Water Conservation Board. “SCPP is one tool in the State’s toolkit that we can all learn from. It can fund innovation, letting water users try something new, because they have that financial certainty. And, because it’s totally voluntary, temporary, and compensated, SCPP lets Coloradans choose for themselves.”
At the September 21 UCRC meeting, Commissioner Mitchell strongly advocated for SCPP reforms that would be responsive to Colorado water users’ input. More information on the revamped SCPP process will be available in the coming weeks. The Congressional reauthorization for SCPP expires in Fall 2024.

What a difference a year makes for the front of Arapahoe County’s Administration Building in Littleton.
Since the 1970s, the west side of the building had been covered by a 3-acre field of unused, water-intensive Kentucky bluegrass.
Recognizing the need to set a positive example regarding water conservation for the long term, in August 2022 the Arapahoe County Commissioners launched a plan to seed the field with a mix of prairie grasses in an effort to transform the bland expanse of bluegrass into a more natural ColoradoScape that will use less water.
The project is part of Arapahoe County’s broader sustainability initiative that includes reducing water consumption indoors and outdoors.
One year later, all the planning has paid off and the grasses are flourishing.

“We’re very pleased with how the grasses have come in and are thriving,” said Lisa VanderHeyden, senior project manager of facilities and fleet at Arapahoe County. “We were lucky and got a nice boost from Mother Nature with all the rain in May and June, which really helped the grasses grow in their first season.”
The old field was chosen for landscape transformation because it was considered to have “nonfunctional grass,” which is grass that requires frequent watering from an irrigation system but is not used for activities or events.

The new field contains a mix of grasses with varying heights and textures. It resembles what the field looked like before people settled the area and started irrigating the land.
It typically takes about three years to fully establish a native grass area, in which the grasses fill in and squeeze out the weeds. Once established, the grass should be able to survive solely on the moisture provided by Mother Nature.
This is how Arapahoe County’s ColoradoScape is going. See how it started.
Arapahoe County’s staff will actively manage the field and the county anticipates saving approximately 1.5 million gallons of water per season due to the switch from the bluegrass.
“The field will have a very natural look and, like other prairie grass fields in the area, the colors will change depending on the amount of precipitation throughout the year,” VanderHeyden said.

Changing landscapes across the Southwest
The building is in Denver Water’s service area and is a great example of a greater push across the Southwest to reduce the amount of nonfunctional grass and help boost the struggling Colorado River, where Denver Water gets half of its water supply.
“We’ve been really impressed with Arapahoe County’s efforts to examine their nonfunctional grass areas and make water-saving changes,” said Austin Krcmarik, water efficiency planner at Denver Water.

“For decades, Kentucky bluegrass has been the default landscaping option for many government buildings and now we’re seeing a shift to more natural looking, water-saving ColoradoScapes.”

Creating a long-term plan
Krcmarik and Arapahoe County agree that there are a number of steps to take when doing large landscape transformation projects:
Consult with the growing number of landscape experts who support water-saving transformations.
Work with landscapers who are willing to research what will work best and commit to support the transformation beyond the initial implementation.
Get the full support of management.
Think the project through, from start to finish and consider long-term maintenance.

Inform the public about the reasons behind the landscape change.
Develop a plan for how to prepare the site for new seeds and plants.
Upgrade and/or modify irrigation systems to protect mature trees if the new landscape will use less water.
Develop a plan to manage weeds during the early years.
Choose plants that can survive without irrigation after establishment.
Denver Water and Arapahoe County are part of the Colorado Native Grass Working Group, which includes dozens of other cities, landscape and water professionals to put together a guide on best practices for installing low-water grass landscapes.

State support
The turf replacement project was awarded a grant from the Colorado Water Conservation Board for supporting the Colorado Water Plan’s goal of encouraging municipalities to reduce water use through landscape change.
“It’s been great working with Denver Water, and we appreciate their support and also the grant from the CWCB,” said Anders Nelson, Arapahoe County public information officer.
“While this is a relatively small field, we hope to learn from our work, share and improve the processes and continue to look for other opportunities to reduce our water consumption here in Arapahoe County.”

The consultant with UnderstandAG — which uses the tagline restoring soil, profits, farms and futures — conducted a water infiltration test in the field that after 10 minutes showed very little water soaking into the hard soil. That is because, for one reason, the field had no armor, or a soil cover of plant residue on the surface. Soil cover is one of the six key elements for building healthy soil that the landowners and ranchers learned about during the all-day Soil Health Field Day on Aug. 15.
“Hay producers might be better off in the long term if they left a 3 or 4-inch stubble of hay, which would help generate a more healthy soil system and by maintaining a continuous living root or ground cover,” said Lyn Halliday, board president of the Routt County Conservation District, which organized the free workshop.
Halliday explained that healthy soils act like a sponge helping to absorb and contain moisture. Low soil moisture can cause plants to stop growing or dry out and may provide fuels for wildfires. On the other hand, when soil moisture content is high, fires have more difficulty in igniting, burning and spreading rapidly.
In the next demonstration area on the property, Fuchs showed with an infrared thermometer the 30-40 degree difference in temperatures of healthy soil versus compacted, poor soil. When Fuchs took a reading of 143 degrees on bare soil, he stopped to take a photo of the startling results because, he said, at 140 degrees, good soil bacteria die. He pointed out a soil temperature study that showed at 130 degrees, 100% of moisture is lost through evaporation and transpiration. At 100 degrees, 15% of moisture is used for plant growth and 85% is lost…
The conservation district recently released a “Routt County Landowner Toolkit for Building Drought, Wildfire and Soil Health Resiliency,” that is online at RouttCountyCD.com. The toolkit includes links to helpful resources with the goal of inspiring county landowners and ranchers to adapt to changing conditions that affect the land and daily practices of farming and ranching. The toolkit points out the best management practices for agriculture include reducing or eliminating tillage, nurturing the living organic components of soils, promoting diversification of soil flora and fauna below ground and plants above ground, creating pollinator habitat, diversifying rotations including grazing, and reducing wind erosion by establishing wind breaks.

The price of water is rising across the Southwest as utilities look to cover the cost of the increasingly scarce resource, the infrastructure to treat and distribute it and the search for new supplies.
PHOENIX—Across the Southwest, water users are preparing for a future with a lot less water as the region looks to confront steep cuts from the Colorado River and states are forced to limit use to save the river. Farms are being paid to not farm. Cities are looking to be more efficient and find new water supplies. And prices are starting to go up.
In Phoenix, the city’s Water Services Department is preparing to increase residents’ monthly water bills starting this October if the hike is approved by the city council. The city isn’t alone. Water providers throughout the entire Colorado River Basin have raised water rates, or are preparing to, to compensate for increasing costs of infrastructure repairs and water shortages along the river. Inflation is driving up the costs of resources to treat and deliver water to customers, and other additional fees are planned to incentivize conservation.
The issue is economics 101, said Casey Wichman, an assistant economics professor at Georgia Institute of Technology and a university fellow with Resources for the Future who studies water pricing. Providers along the basin are coming to terms with the diminishing supply in the river and the infrastructure that needs to be repaired or replaced, largely driven by the rapid growth in population. All of those drive up costs, he said.
“The cheapest way to build new supply is just to get your customers to use less.” To do that, he said, water utilities often turn to raising rates, making the need to incentivize conservation another driver of the increasing price of water.
Finding new water sources and getting people to conserve more is becoming increasingly important as the Southwest grapples with climate change and looks to shore up its supply.
“We have a lot of people living in areas where the water supplies just aren’t there,” Wichman said.
Arizona released a report this month showing the Phoenix metropolitan area was over-drafting the region’s groundwater and announced that moving forward, no new development would be allowed if it relied on groundwater. Throughout the Valley, cities like Phoenix and Tempe are introducing drought contingency plans. Further cutbacks of Colorado River water, particularly in the Lower Basin, which consists of Arizona, California and Nevada, are unavoidable.
The region has experienced more than 20 years of drought and decades of overallocation. Arizona’s supply from the Colorado River has already been extensively cut back, and under a proposal from the river’s Lower Basin states introduced last month and supported by the Biden Administration, the states would agree to cut an additional 3 million acre feet of water over the next three years to prevent Lake Mead and Lake Powell, the nation’s two largest reservoirs, from falling to levels that wouldn’t allow electricity generation at the Hoover and Glen Canyon dams, or the river stops flowing past the dams altogether.

In recent years the Central Arizona Project, a 336-mile-long system that delivers Arizona’s allocation of Colorado River water to around 80 percent of the state’s population, has seen a nearly 25 percent cut in the amount of water that flows through its canal.
The price CAP charges is derived from how much it costs to deliver the water to where it needs to go, said Chris Hall, CAP’s assistant general manager for administration and finance. If less water is being delivered to the state, the price of each gallon will go up.
“We’re spreading that cost over fewer acre feet. It’s really just that simple,” he said. “It doesn’t have anything to do with us having to do any major retrofits to accommodate less deliveries or change our business operations in a meaningful way. It’s just less water.”
This year, the cost of an acre foot of water, enough for about three homes for a year, is $217. Next year it will be $270. By 2028, CAP is expecting the price to rise to $323.
“Water in the Southwest is still, especially in Arizona, relatively affordable,” Hall said. CAP’s goal, he said, is ensuring rates go up in a way that is stable.
Rates Have Long Been Too Low, Experts Say
Among the biggest expenditures in water utility infrastructure are pipelines. In order to fund their repairs and replacements, utilities will have to raise the price of water. Many experts believe that is long overdue, and that water rates haven’t been high enough to keep up with the large investments required to keep infrastructure in acceptable condition.
The City of Phoenix has over 7,000 miles of utility pipelines that deliver water to companies and households. The average water pipe will last 70 to 75 years in Arizona, but a large portion of them are reaching that age where they need to be replaced. While these pipes are built to last using what, at the time of any given pipeline’s construction, are enormously expensive and durable components, corrosion takes place over time and the pipe can crack, introducing contaminants into the drinking water system.
“It is a matter of water quality and water reliability,” said Kathryn Sorenson of Arizona State University’s Kyl Center for Water Policy.
Utility companies and elected officials are reluctant to raise prices, she said, which underfunds these vital investments. Other experts believe water prices across the country are historically low, and increases are inevitable.
“Water is remarkably cheap for the value it provides to individuals and how we can’t sustain life without it,” said Wichman, the assistant economics professor.
But raising rates isn’t a simple task, he said. Cities like Phoenix have a much larger customer base to spread the increased costs over, he said, but rural communities tend to just eat the costs or not increase rates at the pace needed.
Wichman said residents feel the same way about higher water rates as they do higher taxes: They’re not big fans.
At a May public meeting regarding the proposed increase in Phoenix’s water rates, residents were skeptical of the proposal. “I want the city to be a lot more creative in how they search for funds to help cover some of these costs other than just putting it on the backs of the ratepayers,” said Jeff Spellman, a West Phoenix resident, who also questioned how the city would make sure the parts of the city most affected by climate change—like his—get the help they need to confront it.
Residents on fixed incomes, like Spellman, have expressed concern over water increases and how they will affect their lives, as well. “My pension isn’t going up by almost 40 percent like these rates are,” he said.
Higher water rates tend to have a greater impact on people in low-income communities, who generally have less efficient appliances and households with more members, resulting in more use, Wichman said.
He said that utilities often adopt complicated rate structures designed to recover costs, promote conservation and keep fees affordable, but those are all very different, and often contradictory, goals. “Those tend to not work that well,” Wichman said.
There are no laws capping how much municipal utilities can charge per month for water, just some that require it be reasonably priced. The Arizona Corporation Commission, however, has a strict rate-making process, Sorenson said, that is taken very seriously.
Cutbacks, Inflation and Conservation Spike Rates
For providers in Arizona that get water from the Colorado River, the costs are beginning to add up.
Starting this October, Phoenix customers could see a 6.5 percent increase—roughly $2 for the average user per month—with another 6.5 percent increase next March and a final 13 percent increase in 2025. Phoenix Water Services will also impose a water allowance on customers to promote conservation, resulting in a $4 increase each month should customers use more than what is allotted to them.
For Phoenix, the rate increases were born out of trying to find a way to signal to residents how much water they were using, said Water Services director Troy Hayes. The city currently has a flat rate for water until a customer uses a certain number of gallons.
“If you use water below that, your bill doesn’t change,” Hayes said. “So they can go up and go down as long as they stay below that amount. They just don’t have really a concept of the amount of water they’re using.”
Many believe raising water rates is the best, and perhaps the only way to disincentivize citizens from overusing their allotments.
“Back in the 1970s, something like 75 to 80 percent of single-family homes in Phoenix had majority turf or lush landscaping, that number today is down to nine percent,” Sorenson said.

She believes a huge amount of that change is directly related to Phoenix charging more in the summer months for water than winter months, giving a direct price signal that people will pay attention to.
The cost of raw water has gone up 35 percent in recent years, according to the city, but it’s not just the price of water itself driving the change. Inflationary pressures are having big impacts, too, with the chemicals to treat the water to drinkable standards rising by 136 percent.
Measures to reduce the demand on the river and overtaxed aquifers are forcing cities to invest hundreds of millions of dollars to find new sources of water, whether from desalination, agreements with tribal governments, recycling more wastewater or finding new untapped groundwater resources. Those costs, water utility directors and city staff have said, will force utilities to raise rates in the future to pay for the new sources of water.
The pressures from inflation are not isolated to Arizona, though.
Colorado Springs Utilities raised rates by 5 percent at the beginning of the year to address inflation and infrastructure projects. The utility created a separate fund supported by a new fee to purchase other water rights and infrastructure, according to Jennifer Jordan, a spokesperson for the utility. Denver also raised its rates this year.
California has also implemented fees for years to discourage overuse, which is expected to increase.
Representatives from more than a dozen Indigenous tribes spoke at a CU Boulder law conference last week about their interests in the Colorado River from each of their perspectives. Many of the prominent state and federal officials who manage the water attended the conference. But as they and other water authorities prepare to negotiate the river’s future, it’s unclear how tribes will participate, to what degree tribes will be treated as equal sovereigns, and how their desire to use all the water they legally have rights to will be considered. It’s also unclear whether negotiators will aim for a way to make the long-term reductions in water usage that a decades-long megadrought has made necessary or whether they will propose more short-term changes.
The gathering happened at a critical time: Collectively, Colorado River users have to figure out how to live with significantly less water going forward, and the federal government is forcing states to come to an agreement…
The group of tribal representatives and state water officials, along with academics who study the river, used the two-day conference for discussions about how to make their collective use of the river more sustainable over the long term…The tribes have a shared history of using the river and its tributaries over thousands of years and migrating based on water availability. In the century since the river has been dammed and diverted across seven states, each tribe has a different story about how their water rights have been denied and what they seek to change in the river’s management going forward…
Some river scholars and even people with roles in the negotiations are unclear about what’s possible as they determine longer-term allocations of the water…A lot is at stake for tribes, and each circumstance is unique…For example, Hopi Tribe council member Dale Sinquah said his people still need to have their water rights settled. Southern Ute Tribal Council Vice Chair Lorelei Cloud said the tribe wants to use water they have legal rights to in southwestern Colorado, but they don’t have the infrastructure. She said about 1,000 tribal members still have to manually haul water to their homes, and the tribe hasn’t been able to develop farmland…Crystal Tulley-Cordova from the Navajo Nation said her tribe couldn’t rely on groundwater because of abandoned uranium mines on their land. Dwight Lomayesva, vice chairman of the Colorado River Indian Tribes on the border of California and Arizona, said his people would like to upgrade their farming and water infrastructure to make it more efficient, but the federal government still owns it. “The last major change in our irrigation infrastructure was made in 1942, when the United States government built some canals for the Japanese who were interned on our reservation,” he said. Each needs to negotiate for themselves individually.
“To think that there’s an ‘Indian solution,’ really dishonors that individuality and the uniqueness of each one of those tribes,” said Daryl Vigil, a Jicarilla Apache water leader who used to direct a tribal partnership in the Colorado River basin.

The bodacious snowpack means the chance of Lake Mead dropping below elevation 1,000 is zero.
We still need to cut 1.5 million acre feet of Colorado River water use, at least. We still have no plan to do that.
We remain at risk of river flows past Lee’s Ferry dropping low enough by 2026 to trigger a legal argument about what the Upper Basin really owes the Lower Basin.
We have what was called a “historic accord” to reduce Lower Basin use in the short run, which muchly revolves around paying people to not use water.
The “historic accord” does not take any steps toward resolving longstanding tribal and environmental inequities.
The problem of what economist Gordon Tullock called “the transitional gains trap” is a very real obstacle to moving forward on the Colorado River.
WHATEVER, LET’S JUST PAY ’EM: THE “TRANSITIONAL GAINS TRAP”
In a seminal 1975 paper, economist Gordon Tullock nailed the problem at the heart of the current Colorado River policy dilemmas:
Thus farmers in places like Palo Verde, Yuma, and Imperial umpty generations ago benefited from the significant subsidies from the rest of us (federal taxpayers) that enabled Lower Colorado River agriculture to flourish. The benefit of that subsidy has now been fully capitalized in the land and the structures of the communities.
As Tullock’s work so clearly notes, termination of this “scheme” (I love his word) would “lead to large losses for the entrenched interests.”
While there’s a lot of “property rights” framing around our 21st century arguments about this, it’s important to remember that the perfection and continued use of those water rights was enabled by massive collective action on the part of others in establishing the needed institutions, and funding and building infrastructure.
But whatever, right? That’s where we are now, and a fatalistic attitude of “let’s just pay ’em” seems to have settled over basin problem solving, at least in the short term.
IS THERE A “TRANSITIONAL LOSSES TRAP” TOO?
I’m definitely out over the tips of my conceptual skis here, but one of the things that was made clear at the Boulder meeting was something I’ll glibly dub “the transitional losses trap”: the same decisions over the last century that locked in “transitional gains” for Lower Basin farmers also locked in “transitional losses” for Native American communities dispossessed of their land and water.
In a powerful panel last Thursday afternoon, a stage full of tribal leaders one at a time talked about that dispossession. The sheer weight of their words, and the range of their concerns, was breathtaking.
Some progress has been made on this issue, especially in Arizona. But there is no escaping the reality that all that water providing “transitional gains” to Lower Basin farmers is, acre foot for acre foot, a “transitional loss” for Native American communities. And now we’re paying those Lower Basin farmers to not use this very same water.
I get that some of the money we’re paying to reduce water use will go to Arizona and California tribes with settled water rights. But there are many tribes without settled water rights, or with rights that are settled but not yet put to use. They’re getting nothing out of any deal to pay water rights holders not to use their water. We need to remember this fact every time we pay a non-Indian farmer not to farm.
It’s a Lower Basin agreement, among Arizona, California, and Nevada. One of the things that was abundantly clear at the Boulder meeting was that Upper Basin states are withholding judgment until the details are fleshed out.
But it’s already clear that those who negotiated the deal want our money – federal tax dollars – to solve the transitional gains trap, but not to solve any of the other problems worth talking about:
the Colorado River Basin’s tattered environment
unresolved Native American water rights and other needs
As I’ve pointed out previously, with other people’s money should come other people’s values.
THE LEE’S FERRY CONUNDRUM
My buddy/collaborator/coauthor/mentor Eric Kuhn threw up a scary slide during his talk:
The crucially nerdy backstory is in Article III(c) and (d) of the Colorado River Compact, which seem to say the Upper Basin is required to send 82.5 million acre feet every ten years. As Hamby noted, one of the premises of “we need to cut 1.5maf in the Lower Basin” is that the Upper Basin continues to hit that target. Lawyers will argue forever about Article III interpretation, but I’d prefer not to hand over our management of the Colorado River to a judge’s ruling on who’s right.
But the deep entanglement between this question and the transitional gains trap stuff I mentioned before isn’t going away. California farmers have benefited from a “property right” essentially created in 1968 through the use of power politics, but that property right, as Tullock would say, is now priced into the value of their assets. And we’ve now set a “whatever, let’s just pay ’em” precedent (at an unprecedented scale), which does seem historic, but maybe not in a good way.

Like hard rains amid the Dust Bowl, Colorado has lots of water almost everywhere now amid long-term drought. That’s exactly the time to talk about what do as hotter and drier inevitably return.
The Colorado Water Conservation Board chose an awkward time to conduct a drought summit, launching the two-day event on the last day of May at History Colorado in downtown Denver.
It was the fourth wettest month in Denver since 1876, before Colorado was a state, and June got off to a soggy start, too. This followed one of the snowiest winters in decades in some parts of Colorado. The only part of Colorado still in drought is in the state’s southeastern corner.
The somewhat awkward timing was noted by Anne Castle, of the Getches-Wilkinson Center for Natural Resources, Energy and Environment at the University of Colorado Law School. “It’s perfect time to hold a drought summit,” she said with intended irony.
Like others, though, she doesn’t expect this wetness to last. Most of Colorado, including cities and farms east of the Continental Divide, depends upon water from the Colorado River and its tributaries, and it should be news to exactly no one that those who depend upon the largesse of that river have a serious re-reckoning underway. Too slow in some places, according to at several speakers at the conference.
Unlike last year, though, the heat is off. That is good, said Castle. “We can make better decisions when we’re not right in the midst of a crisis, as long as we recognize that one winter does not solve our long-term problems.”
That problem is not necessarily drought, although Colorado and Southwestern states clearly have seen less precipitation in the last 20-plus years. Droughts come and go, and this one in the Colorado River Basin is the worst in at least 1,200 years. Something more is happening here, what scientists call aridification. In aridification, it can snow just as much, but warmer temperatures draw more of the precipitation into the atmosphere. At least one study found that up to 50% of the declined flows in the Colorado River could be attributed to the warming now underway.
Aridification doesn’t roll off the tongue quite so easily as drought, noted Russ Sands, section chief for water supply planning at the CWCB.
Make no mistake, though. Climate change, a subject approached gingerly 20 years ago by state water officials, has become part of the conversation. Consider Greeley.
The once-smallish city located at the confluence of the Poudre and South Platte Rivers has grown to a population of more than 110,000 residents. That is almost certainly just the beginning.
Sean Chambers, director of water and utility services for Greeley, said the city expects to need to expand its water portfolio, currently at 35,000 acre-feet, to 80,000 acre-feet by 2080. “That does not get Greeley to build-out; it’s only half-way there,” he said.
The city gets about 40% of its water from the Colorado River Basin.
Chambers said Greeley is starting to integrate the impacts of climate change into its planning, among them pressures on reservoirs, different times of runoff, and more watershed disruptions.
“All of these risks and challenges on the water system driven by climate change come on top of managing for growth and uncertainties around supply,” he said.
As for its planning, Greeley hopes to keep ahead of hard pressures. Last year, the city gained access to an aquifer to the north of the city that it plans to manage in conjunctive fashion. It can be drawn upon when needed but also used as a storage vessel.
“It’s really difficult to innovate when your back is against the wall,” he said during a panel discussion under a heading of “storage, conservation and innovations.”
Peter Mayer, a Boulder-based consultant who has worked for 30-plus years in water demand management, said conservation has worked very well in Colorado, especially in urban sectors. “That is my specialty. We started in the late 1980s and 1990s and have seen a gradual decline in per-capita use across the state.”
Mayer argued that this has allowed Colorado’s population to grow in a way that has been much less expensive “Because conserved water is much, much cheaper generally than (developing) new supply.”
Greg Fisher, who supervises conservation efforts for Denver Water, talked about the major water reductions in its service territory since 2000, which has allowed Denver to better keep water in its reservoirs. “Conservation really works,” he said.
But there can be tensions within water agencies between programs to reduce water use and the revenue needed to pay for the infrastructure that has been installed, as described by representatives for both Colorado Springs and Durango.
“Your leaders say (conservation) is first, but in the process of setting rates, you tend to find out it’s second or third,” said Jarrod Biggs, from the City of Durango.
“Every councilor wants to make sure that they are saving the last drop and doing what is right for the community and regional partners. When talk gets to dollars and cents, conservation ends up being somewhat important, but it does kind of fall down that list, particularly if you have a very noisy political constituency.”
Castle, from the University of Colorado, who had a law practice for much of her career, pointed out the need for getting land use right, to produce urban landscapes that are less water-intensive. “It’s really the initial configuration of development that is the primary factor that influences future water demand,” she said. We have land-use plans, master plans, comprehensive plans, subdivision improvement agreements. That is where you can deal with and incentivize water conservation and incorporate that into any new development plans.”
Municipal use represents only 7% of total water consumption in Colorado, said Mayer, compared to 91% for agriculture. “What is the agriculture sector doing?” he asked. He suggested the answers can be found with better measuring.
Taylor Hawes, who directs the Colorado River program for The Nature Conservancy with 26 years of experience, talked about the need to pick up the pace.
“We have lost 20% of the Colorado River supply since 2002,” she said. The pace of change must accelerate to correspond with the need. “The longer we wait, the harder it gets.”

Click the link to read the article on the KUNC website (Alex Hager). Here’s an excerpt:
Hot on the heels of a short-term agreement to cut back on Colorado River water use, states are looking ahead to talks about more permanent cuts. The Bureau of Reclamation, the federal agency which manages the West’s water, announced that those negotiations will formally begin next week with a notice in the Federal Register. The announcement came at an environmental law conference in Boulder, Colorado on Thursday [June 8, 2023], where scientists, state and federal governments, and tribes met at the University of Colorado’s law school…
It still remains unclear how exactly the states plan to arrive at permanent cutbacks that will likely be painful to some of the farms and cities that depend on the river’s water, which flows to tens of millions of people and a multi-billion dollar agriculture industry. Pressed for details, state leaders shared little beyond high-level ideas about the need for water conservation across all seven states that use the Colorado River…Becky Mitchell, director of the Colorado Water Conservation Board, emphasized that post-2026 guidelines need to “acknowledge that climate change is real.”
[…]
Camille Calimlim Touton, commissioner of the Bureau of Reclamation, shared new details about the agency’s upcoming plans for water management. The agency has withdrawn its draft Supplemental Environmental Impact Statement while it reviews the proposal, and plans to arrive at a final plan – or “Record of Decision” – by the end of 2023. Reclamation has so far been tight-lipped with details about negotiations related to the 2026 deadline, but Touton said the agency will “formally advance” the process for those multi-year talks starting the week of June 12. Starting the process next week, she said, will allow the agency to publish a new draft SEIS by the end of 2024…
A panel with representatives from 13 tribes spoke about the evolving role of tribes in water negotiations. Officials and attorneys spoke about their current struggles to maintain steady access to clean water, the historic aggression and exclusion that drove them away from water management and the need for tribes’ input as talks continue.
