Pitkin Countyโs Healthy Rivers Board voted unanimously to approve a $28,000 grant request from the Roaring Fork Valley Wildfire Collaborative to fund a project that will produce a wildfire action plan for the valleyโs watershed. The project will identify high-risk areas and potential post-fire hazards in the Roaring Fork Valleyโs water systems to create an action plan in the event of a wildfire. Several town and city water sources come from single streams. In the event of a wildfire, ash could contaminate stream water, degrading the quality of the water system, and potentially making it undrinkable, said Roaring Fork Valley Wildfire Collaborative Executive Director Angie Davlyn during her Thursday presentation to the board in Basalt…
While the Roaring Fork Valley is at significant risk for wildfires, a state evaluation also noted the high susceptibility of the Roaring Fork Watershedโs water infrastructure in the event of a wildfire. This leaves residents, property, and natural resources vulnerable to this disaster but also to other post-wildfire hazards, like flooding and mudslides, Davlyn said…Davlyn also said that the region has been pro-active in performing wildfire mitigation tasks, but there is a lack of a data-driven approach to identify the most critical threats and most opportune areas for a wildfire…To bridge this gap, the Wildfire Collaborative applied for funding from several sources, including Pitkin County. Last week, Wildfire Collaborative signed a contract with the Colorado Water Conservation Board for $224,000 and more than $150,000 in technical assistance for this project, which Davlyn said is the first of its kind in this area. These funds, however, require a 25% match before work can begin. The Wildfire Collaborative will provide half of the match through staff time, but the organization needs Pitkin Countyโs $28,000 to complete the match. Fire Adapted Colorado also awarded $5,000, the town of Carbondale awarded $3,000, Roaring Fork Conservancy awarded $500, Holy Cross Energy awarded $3,000, and other municipalities, counties, and the Colorado River District awarded $5,000. These funds, along with Colorado Water Conservation Boardโs $374,000 and Pitkin Countyโs $28,000, totals $446,500.
hen the state of Colorado created the Groundwater Compact Compliance Fund with $30 million earmarked for recovering the aquifers of the Upper Rio Grande Basin, there was an intention to steer a good portion of the money toward irrigators working in Subdistrict 1 of the Rio Grande Water Conservation District.
Whether the strategy will work is under question. Last monthโs reading of the unconfined aquifer storage levels shockingly showed it at its lowest point, despite millions in tax dollars that have been spent to retire groundwater wells.
San Luis Valley Groundwater
The motivation behind Senate Bill 22-028 was to use state tax dollars to continue to dry out farming fields located in the most productive area of the San Luis Valley because thatโs where the depleted unconfined aquifer of the Upper Rio Grande Basin runs through. For the past two decades the state Division of Water Resources has been working with Rio Grande Water Conservation District and the farmers and ranchers who operate in Subdistrict 1 to reduce the amount of groundwater they pump each growing season to help recover the struggling aquifer.
The 2022 state senate bill would bring new money into the effort. Of the $30 million allocated from Groundwater Compact Compliance Fund to the Upper Rio Grande Basin, nearly $14 million has been directed to retire 44 more groundwater wells in Subdistrict 1, with more money likely to come to further the strategy.
The state monitors the amount of groundwater pumped with flow meters tied to center pivot sprinklers which water the fields. The meter reading will tell the farm operator how many acre-feet of water theyโve used during the irrigation season, and each fall figures from those flow meters are reported to the state.
The assumption has been that by reducing the amount of groundwater pumped from the unconfined aquifer, the aquifer would recharge over time. Over the past decade, it appeared the strategy had validity with the aquifer at times showing a bounce back.
Then came the reading from this August which showed the unconfined aquifer storage near its lowest level, and state and local water managers found themselves scratching their heads in disbelief and frustration.
โIt is disappointing to see that the aquifer has dropped lower this year. We had hoped to see an increase in aquifer levels, but another lower-than-average river flow year meant that less water was available to recharge the aquifers,โ said Craig Cotten, the state division water engineer in the San Luis Valley.
The continued decline in unconfined aquifer levels is the reason the state engineer this year approved a new Groundwater Management Plan that is included in the Subdistrict 1 Fourth Amended Plan of Water Management. The plan was more than a year in the making and still needs approval from the state water court to go into effect. That wonโt happen at the earliest until sometime in 2026.
Meanwhile, the clock is ticking.
โIt is very concerning, especially given that Subdistrict #1, under its current plan, has just seven more years in which to recover the unconfined aquifer to a sustainable level. If the aquifer has not recovered by then, and if the subdistrict is still operating under its current Groundwater Management Plan, then the State Engineer will have no choice but to curtail all of the non-exempt wells in this area,โ Cotten said.
There are several โifsโ in that scenario, all of which should get addressed when the state water court takes up the new Groundwater Management Plan for Subdistrict 1. But again, thatโs not until 2026, and the clock, as Cotten mentions, is ticking.
Amber Pacheco, deputy general manager for the Rio Grande Water Conservation District, said there are 3,614 wells included in the Subdistrict 1 annual replacement plan. The idea that the state would come in and shut those down because farmers couldnโt recover the unconfined aquifer to a sustainable level is the constant worry Subdistrict 1 farm operators work under.
โThere is no specific timeline in which the Subdistrict will meet its objective to reach a Sustainable Water Supply by reaching an Unconfined Aquifer Storage Level between 200,000 and 400,000 acre-feet below that storage level that was calculated to exist on January 1, 1976, but it may be 20 years or less depending on the hydrologic conditions following the period the new plan is implemented,โ Pacheco said.
Take a drive down County Rd E or any of the other country roads that cross through Rio Grande and Alamosa counties and youโll notice the Valleyโs potato harvest in full swing. Take a bit closer look, and in the midst of the harvested fields is a growing amount of agricultural acreage once productive that is now intentionally dried out to save on the groundwater below.

With the unconfined aquifer showing little to no bounce back after years of attempted recovery, the expectation is that the western and northern ends of the San Luis Valley will see more dry fields in the growing seasons to come. The money spent through the stateโs Groundwater Compact Compliance Fund to retire more groundwater wells will begin to show up in the 2025, 2026 planting seasons and beyond.
As Cotten said, Subdistrict 1 is โone of the most productive irrigated farming areas in the state.โ
Farming with a struggling aquifer is making it less so.

This spring, I had the pleasure to sit on a panel on water in the West with Paolo Bacigalupi and Heather Hansman, two writers Iโve long admired. During the question & answer period, a local woman lamented the fact that some ditches were being piped or lined with concrete, because it would dry out the wetlands and ecosystems that had come to rely on the leaky laterals and ditches. And she was angry because the point, as she understood it, was to save water only to send it downstream to California. Her beloved valley, it seemed, was being dried out to fill up LA pools, which just seems wrong.
Jonathan P. Thompson, Paolo Bacigalupi, and Heather Hansman on a writer’s panel in Paonia in April, 2024.
Iโve thought about this a lot in the months since, because I think it gets down to the big, conceptual tug-of-war thatโs happening around the Colorado River. Thereโs one battle between the different users of the riverโs water. And then thereโs another in which the values different communities hold are clashing with the โlaw of the riverโ and the overwhelming math that is driving the need to make massive changes.
The following meditation on this clash was catalyzed by a slide a friend sent me from a Family Farm Alliance presentation at the Colorado Water Congressโs summer meeting. It accused me โ via a piece I wrote for High Country News โ of โdemonizingโ alfalfa.
Well, Family Farm Alliance, this is my response to you:
VALUES
The woman at the panel was referring to the North Fork Valley in western Colorado, a place with an extensive network of open canals, laterals, and ditches that irrigate peach, apple, and pear orchards, small vineyards, organic farms, and alfalfa fields. A handful of center-pivot sprinkler systems reveal themselves in the geometric perfection of their dependent fields, but most of the farms rely on older methods to bring water to the crops, namely by flooding the field or directing water down dirt rows where they soak into the plantsโ roots.
Most of the canals and ditches are unlined and uncovered, and have been that way since they were built over a century ago. Many of them leak, some prolifically, their fugitive water blanketing the beige-gray earth with grass and nourishing cottonwoods, feral apricot and plum trees, sunflowers, willows, cosmos, reeds, sweet peas, milkweed, and cattails โ along with a host of fauna that depend on those plants.
The intentional and accidental irrigation combine to form an irregular, pastoral patchwork of relative lushness amid the arid landscape of the kind that can be found in northern New Mexico, where a network of acequias irrigate long, rock-lined fields, or McElmo Canyon, where voluptuous pink sandstone rises up from a sea of emerald alfalfa. These places, where the cultivated and feral and wild collide, evoke the Provence of Jean Gionoโs novels.
These are artificial landscapes, colonial ones, even, created by damming rivers and diverting their waters away from the fish and aquatic life in the streams and throwing off the natural balance of things. They rely heavily on inefficiencies in the system, from leaky laterals and ditches to flood-irrigation runoff. But they are, to my eye, lovely nonetheless, and contrast favorably with the more efficient farming areas, where high-tech irrigation systems deliver every drop of water to the linearly planted crops in laser-leveled fields.

And yet, because of math and water laws and compacts and the need to devote every drop of the shrinking Colorado River to โbeneficial uses,โ the character of these landscapes is likely doomed. It wonโt happen next month or even next year, but over time. Nor will the lands be dried up altogether: In places like the North Fork the ditches โ at least the ones with senior water rights โ will continue to deliver water to the fields.
But more and more, those old leaky ditches will be upgraded, lined with concrete or other impermeable materials, or even put into pipes so that all of the water goes to those who hold the rights to that water, not to evaporation or the accidental ecosystems that have sprung up along the ditchesโ banks. The farmers, too, may be forced or incentivized to become more efficient, replacing the flood irrigation with sprinklers or drip lines. Some will be paid to not irrigate at all. Most of the open ditches like the ones my cousins and I held stick-boat races in on my grandparentsโ Animas Valley farm will be gone, along with the runoff of the kind that spilled from their corn and alfalfa fields to fill the cattail- and willow-tangled slough down below.
It is this loss that the woman in Paonia is mourning. It is heartbreaking. And itโs something I think about every time I write about the Colorado River and the looming crisis it and the communities and industries that rely on it face in the not-so-distant future.
If the crisis could only be solved โ and the needed cuts in consumption made โ based on our values alone, things would certainly be a lot easier. There would likely be fairly wide agreement that we should fallow the golf courses and drain the swimming pools before drying up the leaky-ditch wetlands and leaving the red-winged blackbird homeless. Farmers might join me in calling for tearing out thirsty turf lawns from Denver to San Diego, implementing progressive water rates to stem gluttony, and putting hard limits on household water use โ if it meant keeping the sprinklers flowing to food crops, including alfalfa and other forage. After all, I value cheese and ice cream and green-chile burgers over the Sultan of Brunei or Miriam Adelson, who guzzled 12 million and 10 million gallons of water, respectively, last year to keep their Las Vegas estates green.
Ah, and yes, if all of this could be solved by prioritizing cuts based on values, alone, the Family Farm Alliance would have no reason to accuse me of โdemonizingโ alfalfa and other livestock forage crops (though I imagine the golf groupies would get me for vilifying them). But, alas, itโs just not that simple. Why? Because even the most lofty values are trumped by the cold, hard math.
MATH
The pertinent numbers in the equation include:
16.5 million acre-feet: Total human-related consumptive use of Colorado River water in 2020. This means all of the water that was withdrawn from the river and not put back into it, including reservoir evaporation. It doesย notย include the 2.8 million acre-feet consumed via riparian and wetland evapotranspiration, nor does it include the 1.7 million acre-feet of water use from the Gila River, a tributary to the Colorado.ย
14.5 million acre-feet: The Colorado Riverโs median โnatural flowโ at the Lee Ferry stream gage, which is the official dividing line between the Upper Basin and Lower Basin, from 1906 through 2023. This is used as a measure of how much water is in the Colorado River, since downstream tributaries are relatively insignificant.ย
12.4 million acre-feet: The Colorado Riverโs average natural flow at Lee Ferry from 2000 through 2023.
This leaves us a few options for the big math problem that needs solving:ย
The optimistic equationย (assumes the last 20 years was an anomaly and the river will go back to its old-normal flow soon, i.e. the median for 1906-2023):
14.5 million – 16.5 million = 2 million acre-feet deficit
The new-normal equationย (assumes the next few decades will look like the most recent couple of decades โ which is to say a megadrought) :
12.4 million – 16.5 million = 4.1 million acre-feet deficit
The pessimistic (realistic?) equationย (assumes human-caused climate change will continue to deplete the river):
10.4 million – 16.5 million = 6.1 million acre-feet deficit
Estimated natural flow of the Colorado River at Leeโs Ferry (the dividing line between the Upper Basin and the Lower Basin). The natural flow is basically the total amount of water the river delivers each year, or the volume that would pass by Leeโs Ferry if there were no upstream diversions. Source: USBR.
Which is to say โฆ weโre screwed no matter how you juggle the numbers! Sorry, thatโs not very solution-oriented is it? No matter how you cut it, though, the Colorado River budget is running a massive deficit and has been for a while. Thatโs why Lake Powell, the Upper Basinโs savings account, has been shrinking and now is less than 40% full โ even after a couple of decent winters. A couple of consecutive new-normal winters could bring the reservoir down below minimum power pool, shutting down the hydropower turbines and potentially setting the scene for a mega plumbing disaster.
While itโs highly unlikely that the Colorado Riverโs flows will increase enough to fill Lakes Powell and Mead to capacity anytime soon, itโs not impossible. During the extraordinarily wet and snowy four years between 1983 and 1986, nearly 80 million acre-feet of water ran into Lake Powell โ which should be enough to fill both reservoirs and still deliver adequate flows downstream. If it happens, great! It would be foolish and potentially catastrophic to bet on a repeat, however.
That means the users of the river must erase the deficit by cutting anywhere from 2 million to 6 million acre-feet of consumption annually. The big question, and one that the basins and their member states have been debating, is: Where will those cuts come from? Iโm not going to get into the many layers of these negotiations here, as thatโs not the purpose of this essay, which is a bit of a thought experiment. Suffice it to say itโs complicated, and made more so by glaring errors and injustices committed when the Colorado River Compact was originally crafted.
Letโs say weโre going to make these cuts based on values. Obviously everyone has different values, so weโll just go with those expressed at the Q&A session I lead this piece with, which can be summed up as prioritizing rural farmland, food crops, and the artificial wetlands that can be found in the North Fork Valley over urban lawns, golf courses, and billionairesโ estates.
Where better to begin than Las Vegas? Letโs pull up some water user data and, holy cow! Look at those numbers. The Vegas resorts and the rich sure know how to use water:
The Venetian and Mandalay Bay resorts each use more than 500 million gallons of water per year. Meanwhile the top residential water users are mostly billionaires: 99 Spanish Gate Dr. โ which goes through 12 million gallons per year โ was owned by the Sultan of Brunei until tech-giant Jeff Berns purchased the 37,500 sf mansion for $25 million. Other top water gluttons include Miriam Adelson โ a top Trump donor โ and UFC CEO Dana White. The average Las Vegas household uses about 120,000 gallons per year, though newer, more efficient homes use far less.
When folks start throwing $25 million around for an unfinished house is when you know itโs time for a wealth tax. And when they use 100 times as much water as the average home, itโs also time for a new, progressive water rate structure, that incentivizes conservation and punishes gluttony. Las Vegas already has something like this, but the rates in the upper tiers are too low to be meaningful; they need to be so high that this kind of profligacy will sting even a billionaireโs pocketbook. Hell, better yet, why not just fallow these properties and xeriscape them?
When the numbers are added up, youโve got:
227,243,000 gallonsย Top 100 Las Vegas residential water usersโ combined consumption in 2023.ย
3,774,780,000 gallonsย Top 10 Las Vegas non-residential water usersโ combined consumption in 2023.ย
Wow, so by shutting down just these folks, we could save 4 billion gallons of water, or โฆ 12,275 acre-feet? Oh, thatโs not as much as it seemed.
So how about we go to other cities and tear out turf, mandate low-flow appliances, ban lawn watering and swimming pools. I mean, if you could get Scottsdale and St. George residents to cut back to Tucson or Los Angeles per capita water levels, youโd make some more huge cuts.
If Scottsdaleโs per-capita consumption were cut to Tucsonโs levels it would save about 42 million gallons per year.
You could save millions of gallons through that effort, which is great. The problem is, this problem requires bigger thinking โ youโve got to make multiple cuts in the tens of billions of gallons range for it to make a significant difference. Once again, math, the ultimate buzz killer, raises its ugly head. See, as noble as all of these efforts might be, there just isnโt enough overall water use in the urban sector to come up with all the necessary cuts. You could drain the pools, dry up the lawns, seal up the Bellaggio fountains โ hell, even shut off the massive pumps that convey water from Lake Mead to the Las Vegas metro area altogether โ and you would still need to come up with at least another 1.6 million acre-feet of cuts. Entirely cutting off all of the Basinโs cities and industrial applications wouldnโt even get you to 4 million acre-feet of cuts. But boy, it sure would be interesting to watch โ from afar.
To conclude Part I, some charts that drive the point home:
Irrigated agriculture gulps up about 10.1 million acre-feet per year, accounting for about 52% of the total consumptive use on the Colorado River. Meanwhile the municipal, commercial, industrial sector only uses 3.5 million acre-feet, meaning if you cut off all of the water to every Southwestern city, you still might have a water deficit in the Colorado River Basin. Source: New water accounting reveals why the Colorado River no longer reaches the sea, by Brian Richter et al
The chart on the left shows consumptive use within the Colorado River watershed only, where irrigated agriculture uses about 50% of the water. By contrast, Colorado River water sent over the Continental Divide to Coloradoโs Front Range and New Mexicoโs Rio Grande watershed is mostly used by cities, with about one-third going to agriculture.
About 59% of the non-exported Lower Basin consumptive use goes to irrigated agriculture. Exports follow the same pattern as in the Upper Basin, with most of the water going to urban use.

Nearly 150,000 residents will have greater access to safe drinking water without high costs for decades to come, after an approval by the Colorado Department of Public Health and Environment (CDPHE). This authorization will increase capacity at the Soldier Canyon Water Treatment Plant from 60 to 68 million gallons per day (MGD).
โThe approval from CDPHE is a big win and a huge savings in dollars for the Tri-Districts all operating from the Soldier Canyon Water Treatment Authorityโs Plant,โ says Eric Reckentine, General Manager of North Weld County Water District.
The re-rating by the CDPHE which increases capacity from 60 to 68 million gallons per day (MGD), was successfully accomplished by the collective work of the three water districts operating out of Northern Colorado โ North Weld County Water District (NWCWD), East Larimer County Water District (ELCO), and the Fort Collins-Loveland Water District (FCLWD).
โThe expansion ensures that we can continue to provide water supplies to match our customersโ future growth needs and provide added resilience to our water supply systems,โ states Mark Kempton, P.E, CWP, General Manager of Soldier Canyon Water Treatment Authority. โThe Authority achieved the 8 MGD expansion using the Plantโs existing facilities, resulting in no construction and minimal costs. This efficiency has allowed us to keep our water rates low for our customers while continuing to provide a reliable, safe, and affordable drinking water supply to the Tri-Districts.โ
The CDPHE expansion will provide water and larger capacity many years into the future for the tremendous development and population growth that Northern Colorado towns are experiencing.
โWe continue to see projections for additional growth in the northern Colorado region and expanding water treatment capacity is a fundamental building block to sustain that growth. This treatment capacity increase represents the most cost-effective expansion in Soldier Canyonโs history and ensures all three partners can continue delivering high-quality drinking water well into the future,โ explains Chris Pletcher, P.E., General Manager of Fort Collins โ Loveland Water District.
โLike much of Northern Colorado, we anticipate continued growth within the East Larimer County Water District (ELCO) service area, and this addition of water treatment capacity will aid in meeting that new demand,โ states Mike Scheid, General Manager of ELCO.
โI am very proud of the work of the other water districts and the staff and board of North Weld County Water District for helping to make accomplishments like this happen โ it further stands by our commitment that we follow-through on what we promise for our customers,โ says Reckentine. โThis collaborative undertaking between the districts ensures we have secured the highest quality treated water for our Northern Colorado customers today, tomorrow, and into the future.โ
ABOUT THE SOLDIER CANYON WATER TREATMENT AUTHORITY:
The Soldier Canyon Water Treatment Authority (SCWTA) owns and operates the Soldier Canyon Filter Plant, which is a 68 million gallon per day (MGD) conventional water treatment plant located in Fort Collins, CO. Since 1961, the Authority has provided high quality, reliable, safe, and affordable drinking water to over 145,000 people living in three water districts and adjacent communities in the Northern Colorado region. The three water districts (Tri-Districts) are:
The U.S. Air Force has a plan for cleaning up a decades-old jet fuel spill from a base near Albuquerque.
However, the local water authority said last week that the plan is inadequate, in part because it scales back current remediation efforts and doesnโt mention how the Air Force will address sudden issues.
In 1999, officials discovered a fuel leak, assumed to be more than 24 million gallons, in the jet fuel loading facility at Kirtland Air Force. The leak could be twice the size of the infamous Exxon Valdez oil spill of 1989, according to the Global Atlas of Environmental Justice.
Itโs unclear when the leak โ the largest underground toxic spill in U.S. history โ first occurred, but it had been spilling fuel into the ground for decades by the time it was discovered, according to Kelsey Bicknell, environmental manager at the Albuquerque Bernalillo County Water Utility Authority.
An Air Force report says existing measures have prevented further migration of the fuel contaminants and that officials are regularly taking groundwater samples to ensure that drinking water remains safe both on and off-base.
Bicknell said there are concerns with the way the Air Force plans to go forward, including a lack of forward-looking analysis and the absence of a โtrigger action planโ that identifies possible changes and prescribes a response to those changes.
She told the water authorityโs Technical Customer Advisory Committee that the fuel soaked its way through almost 500 feet of soil, and ultimately reached the water table, where rock wouldnโt permit it to drop further. Then, she said, it began to pool underground.
Bicknell said the fuel not only contaminated the groundwater but also released volatile vapor into the nearby atmosphere.
She said the Air Force used a vapor extraction system to clean up more than a half-million gallons of fuel.
โThis was a really successful system,โ Bicknell said, adding that the program was shuttered after about a decade.
Bicknell said the Air Force is now using a groundwater pump-and-treat system that targets the dissolved fuel components that have moved away from the source of the leak and area. There are also four extraction wells, brought online between 2015 and 2018; they draw out and treat groundwater.
Bicknell said the Air Force has announced plans to turn off two of the wells. But that was done without input from the water authority and without including the agency in decision-making.
Air Force representatives did not immediately respond to phone and email requests for comment.
Bicknell said the goal now is to try to get the Air Force to reverse its decision before the wells are shut down. State and federal regulators have jurisdiction over the cleanup plan, she said, but the water authority cannot veto what the Air Force wants to do.
โUltimately, weโre the water carrier, the ones that are impacted,โ Bicknell said. โIf the Air Force messes up, it is our source water thatโs impacted, and itโs us that lose out on access to a supply source, so including us in the room and in project discussions and decision-making is something that is paramount.โ
The San Juan Water Conservancy District (SJWCD), with a grant from the Colorado Water Conservation Board, has released the first of three short educational films regarding the watershed and the future of the water supply in Archuleta County. The video, โThe Value of Snow,โ will be shown in multiple venues in the county and can also be viewed online via the SJWCD website: sjwcd. org. The SJWCD is organized and funded by the citizens of Archuleta County to be an active leader in all issues affecting the water resources of the Upper San Juan River Basin. In order to enhance the understanding of our limited water resources, the district employed professional filmmaker Christi Bode to produce these films.
All water uses โ environmental, agricultural, recreational, industrial and municipal โ are important and need to be understood. It is the goal of the SJWCD to use these tools to help our constituents gain knowledge and understanding of the benefits and the risks associated with our watershed and the water it provides. Our communityโs economy and our residentsโ well-being are directly dependent on the health of our watershed. The risks are many and include drought, wildfires, mass earth movements (landslides), pollution and diversions.
Currently, Coloradoโs hunters and anglers have perhaps a once-in-a-lifetime opportunity to protect a wide swath of public lands habitat in southwest Coloradoโs Dolores River Canyons region. In April, we joined hunters, anglers, rafters, business owners, and many others from across the state and region inย supportingย a proposed Dolores River Canyons National Monument…The Dolores River faces threats from industrial scale mining, habitat fragmentation, and unmanaged recreation. Protecting intact habitat for mule deer, elk, and desert bighorn sheep, particularly winter range and movement corridors, is essential for retaining quality sporting opportunities. Now is the time forย action. A national monument designation will help everyone better manage the change that is already occurring while also protecting public lands habitat and ensuring future generations of hunters, anglers, and many others experience the area as we have.ย For additional information seeย Sportsmen for theย Dolores.
Decades of drought and taking more water from the Colorado River than it can afford to give have put both the river and the $1.4 trillion economy it supports in jeopardy. Investing in water resilience is essential for companies operating in the region, but it requires a different approach than many are used to.
A tested and successful model can be found on the Verde River, a Northern Arizona tributary of the Salt River in the Colorado River Basin. The Verde River provides water for local farms and delivers up to 40 percent of in-state surface water for major urban locations in the Phoenix metro area. But its long-term health is at risk from withdrawals, groundwater pumping, a warming climate and drought.
Companies including Boeing, REI, Coca-Cola, Meta, Microsoft, Cox, PepsiCo, Google, Procter & Gamble, EdgeCore and Intel have partnered with groups such as The Nature Conservancy, Friends of the Verde River, National Forest Foundation and the Salt River Project to support dozens of resilience projects over the past decade in the Verde River. The Nature Conservancy (TNC) reports that over the past five years, projects spanning seven irrigation districts have saved nearly 50,000 acre-feet of water. Thatโs enough to support 100,000 U.S. households for a year.
These projects have focused on creating healthier streams and wetlands, reducing the risk of catastrophic wildfires and increasing the efficiency of water delivery systems. Here are some examples.
Reducing wildfire risk
An overabundance of small shrubs and trees in the Verde Riverโs forested headwater areas significantly increased the risk of devastating wildfires that would affect communities and regional water supplies and infrastructure. Partnerships that include agencies, nongovernmental organizations and corporate funders have scaled up projects that remove overgrowth and restore healthy forest conditions. This work has reduced fire risk, improved water availability and increased water security for the region. Corporate partners, including EdgeCore, PepsiCo, Apple, Meta and Google, were critical to the success of these projects.
โMetaโs water stewardship efforts include investing in projects that help put in place the enabling conditions for sustainable water management,โ said Stefanie Woodward, water stewardship lead at Meta. โWeโre proud to support projects that help to restore healthy forest conditions in the Verde and empower environmental nonprofits and communities to build long-term capacity in Arizona.โ
Increasing water conservation
Outdated irrigation ditches convey water from the Verde River to farms across the middle Verde watershed. Leakage across many miles of the system increased the amount of water withdrawn from the river and made it difficult to irrigate farmland.
Multiple Verde River irrigation districts partnered with The Nature Conservancy to pipe more than 4 miles of irrigation ditch and improve water management by installing new water control structures. The work has increased water conservation and improved streamflows. Companies participating in the project include Swire Coca-Cola USA, Coca-Cola, Procter & Gamble, Meta, Coors Seltzer, Microsoft, PepsiCo, Advanced Semiconductor Materials (ASM) and Pulliam Trust.
โTogether with The Coca-Cola Company, our support of conservation organizations along the Verde River aims to address the critical water challenges facing this vital ecosystem,โ said Mike Bernier, director of sustainability at Swire Coca-Cola. โBy funding projects like the piping of the Verde Ditch, weโre helping implement a long-term solution to reduce leakage, in turn improving water-efficiency and ensuring the sustainability of this water source for millions downstream.โ
Shifting agricultural water demand
Many traditional crops in the Verde Valley are water-intensive and require significant irrigation during summer months when river flows are low. A partnership that includes Sinagua Malt, TNC and local farmers implemented an innovative program that replaced high-water-use crops, such as alfalfa, with barley, which requires less water in the summer season. The project delivered a solution that provides brewers with premium Arizona malt while improving water flows in the Verde River.
Tamarisk
Improving river flows
In addition to conservation and efficiency projects, removing invasive plant species can also improve water flows. Companies and funders including REI, Intel and Forever Our Rivers each funded work to remove invasive Arundo and Tamarisk plants from the middle Verde River and areas near the mouth of the Verde on the Salt River. These plants force out native vegetation and can use water at a higher rate. Removing them has helped restore habitat, improve biodiversity and keep more water flowing in the Verde River.
Setting the stage for success
Ready-to-fund water resilience projects that directly reinforce corporate goals are rare. Understanding the history and context for the Verde River work can help companies replicate success in other areas.
Social stronghold: Most projects in the Verde developed in areas where extensive groundwork had already been done by organizations that would later partner with corporations. Nonprofit groups and agencies spent time building relationships and credibility with landowners, agencies and partners prior to corporate investment. A foundation of social infrastructure was in place, or was positioned to expand.
Takeaway:Consider the need to support essential enabling actions such as planning, project design or outreach. Itโs rare that โshovel-ready projectsโ are lined up in the right places and on the right timeline to perfectly align with corporate goals. Understanding and supporting pre-project strategies, including relationship building, can be essential.
Community relevance: A shared understanding of water challenges and solutions is necessary to achieve progress. There must be an overlap between community, corporate and conservation goals. On the Verde River, an analysis conducted by TNC and others of water issues, challenges and solutions helped identify areas where community interests intersected with corporate and conservation priorities.
Takeaway: Long-term, larger-scale resilience projects require significant community buy-in to succeed. Specific corporate stewardship, volume or replenishment goals should be based on a solid understanding of local priorities and context. This includes current public sentiment as well as the availability, likelihood, cost and timing of projects in a given location.
The long game: Many projects require years of preparation โ for example, overhauling and improving centuries-old irrigation ditches that cross many land ownership boundaries required years of trust-building, engineering, problem-solving and fundraising. In the case of the Verde, several philanthropic organizations, including the Walton Family Foundation and the Nina Mason Pulliam Charitable Trust, provided early funding that allowed on-the-ground partners to build trust incrementally and set the stage for later success. It took 5-10 years to fully develop a pipeline of projects that could be funded and linked to corporate goals.
Takeaway: Be realistic and informed about the timeline and partnerships required for success. Corporate timelines should reflect real conditions and needs on the ground.
Setting flexible goals: Goals that rigidly define success metrics can create a scenario in which targets cannot be achieved โ or where corporate goals do not address the real issues and concerns of local communities. For example, a narrow, inflexible goal such as โby 2030, our company will support projects that reduce water contaminants by at least 20 percent in all regions where we operateโ will make it difficult to adapt to real conditions and needs that reflect evolving water challenges and community priorities across diverse locations.
Takeaway: Invest in multiple projects and set goals that are flexible enough to respond to local conditions, needs and context. Donโt expect a single project or narrow approach to meet both corporate water objectives and relevant regional needs.
On a cold, wet Monday morning, hidden away in a tall aspen stand, Rosalee Reese and Connor Born whisper so they donโt disturb the nearby rehabbing bears and bobcats. They walk into a large chain-link enclosure. In one corner sits a stock tank filled with murky water. In the other corner is a den-like structure of hay. A piece of plywood is laid over the top. Reese, Born and two employees of the Frisco Creek animal rehab center use sticks and their wits to corral five beavers into kennels.ย

These beavers are part of the Beaver Translocation Program and are the third group this year to be relocated from the Valley floor to the Rio Grande National Forest. โProblemโ or โnuisanceโ beavers are more often than not, just killed. When their dam building collides with agriculture or when they are perceived to be displacing water levels or threatening water rights, beavers are seen as pests and are treated as such. The hope is that this program will eventually lead to less conflict and more coexistence.
The future, Reese and Born say, is coexistence.
From Frisco Creek to Rios de los Piรฑos
The Beaver Translocation Program is a part of the Rio Grande National Forest Wet Meadows Restoration Project. The Rio Grande Headwaters Restoration Project and the Forest Service have partnered on a new pathway for beavers to be placed higher in the mountains where they can have more direct influence on the watersheds and avoid the nuisance label. Projects like these have sprung up over the United States and in Canada, but work really didnโt start in Colorado until about two years ago.
โThereโs always going to be conflicts on the Valley floor,โ said Born, stewardship coordinator for the Rio Grande Headwaters Restoration Program. โI think of this as much a service to irrigators and water rights holders in the Valley as it is a benefit to the forest.โ
Beavers play a vital role in watershed health; their impacts on the environment as a whole are widespread and well-known. However, where beavers excel in some places, they can be real problems in others. Particularly on the Valley floor, where their work and the work of farmers and ranchers collide.
โIf you have suitable habitat for beaver, youโre going to continue to have problems with beavers,โ said Reese, forest fisheries biologist for the Forest Service. โIf we come and trap them out and move them, if you shoot them, the likelihood is that theyโre going to come back at some point.โ
She said that coexistence and making areas resilient against the beavers can โmake your life easier because youโre not going to be dealing with the same issue over and over again. Because youโre not going to be able to eliminate beaver from the Rio Grande Basin.โ
There are ways to create cohabitation, but it takes time and it takes money. The money, though, wonโt come out of the pockets of those in conflict with the beavers. In fact, Born said, the approach is to offer funds to encourage people not to kill nuisance beavers and allow the animals to be relocated.

Reese and Born, with two adult beavers, two yearlings and a kit, load into a Forest Service truck and drive the length of the Valley until they are high in the Rio Grande National Forest. For those few hours, the five beavers traveled faster and further than they ever have before.
Beavers are natureโs engineers, second perhaps only to humans. Yet there is an age-old tension between us and them that has forced us to think differently about what techniques can reduce conflicts and make sure that the Rio Grande National Forestโs watersheds and the Rio Grande stay healthy.
Overgrazing and drought are two factors at play that threaten watersheds and streams. The relocated beavers will call the Rios de los Piรฑos home and even though their future is somewhat cloudy, they have been given another shot at life and an opportunity to do their jobs.
If thereโs enough habitat, theyโll stay together as a multi-generation family unit. But if thereโs limited food or habitat theyโll move away.
At the release site, Reese and Born pull on their waders. Reese comforts the beavers who at this point have huddled into the corners or against the gates of the kennels, eyes wide and hearts racing.

Reese and Born tie two ratchet straps around the kennel and thread two wooden poles on either side. They take three trips from the truck to the drop off site, up to their thighs in water, carrying the beavers on makeshift gurneys.
The summer rains have created a swift and flowing rush of water.
The three kennels sit side by side. Reese and Born open the gates and coax the beavers with words of encouragement. Nothing happens for a moment. The animals are afraid and a little camera shy.
The kennels are tipped up and lightly shaken. The first beaver to take a swim is the baby. Then one by one, the other four beavers make their way into the water, where they slide in and slip under the surface.
And just like that, the job is done.

The Forest
Beavers are considered an Aquatic Focal Species or Aquatic Priority Species. This means biologists and experts can look to them as an indicator of watershed health.
โSo then we monitor a beaver and do the beaver relocation program as a metric of monitoring our watershed and riparian health and hopefully improving it in areas where we can re-establish them,โ Reese said.
The beavers are being introduced to some areas they inhabited 20 to 30 years ago, but were pushed out due to drought or overgrazing, food and habitat pressures, or even simply by being killed.
In the short term, beavers are most threatened by predation, mostly by bears and mountain lions.
In the long term, besides climate change and overgrazing, human conflict remains the biggest threat to beaver populations.
Reese said that even when problem beavers are moved up into the mountains, they can still be seen as a problem and killed. And thereโs not really a lot anyone can do about it.
โTheyโre just getting killed,โ she said. โWe have to change peopleโs perspectives on beavers. Humans are going to be one of the major issues for recovering larger beaver populations.โ
Beavers are a protected species in Colorado, but if beavers are damaging property or causing problems to irrigation or agriculture they can be killed under state law.
Not all farmers and ranchers are so eager to kill beavers. Some are quite understanding of beaversโ role in nature, but just donโt want them gunking up agricultural gears. Born said that some landowners who are willing to participate in the relocation program are also willing to wait until next season to have their problem animals removed.
Understanding beaversโ role in the ecosystem is half the battle.
However, it doesnโt mean that people like Reese and Born wonโt continue to try and give the watersheds and the beavers another shot. In the national forest, thereโs no shortage of good places for beavers to be left alone to do their work. Particularly in meadows.
In the meadows that beavers occupy, their dams act like sponges, soaking up water and dispersing it far and wide. Born said, โYou have this whole mini-aquifer of groundwater that if the beaver dam is there is just full. And that sponge is going to help release water longer into the season and keep the river wet. Itโs just the same as the Rio Grande and the aquifers here.โ
Thereโs a direct relationship between beavers and water health.
Credit: Owen Woods
โIf the stream is cut off or forced to one side of the Valley,โ he said, โthat sponge is no longer fully wet so youโre more prone, if thereโs no rainfall or low snowpack, then all of a sudden you lose flows completely or greatly reduced.โ
On the car ride to the Rio Grande National Forest office in Del Norte, Born tells The Citizen that because of this mini-aquifer effect, some people may take it a step further and say that beavers and processed-based restoration have a potential to create a โsecond run off.โ
โI donโt exactly like that terminology because I think it really overplays the potential,โ he said.
Thinking on a stream-by-stream basis, he said, โwe are so, so far from having any kind of meaningful influence on a river like the Rio Grande or Conejos. These are small streams that weโre doing habitat improvements for fish, for riparian habitat, and the groundwater recharge is almost secondary in these projects.โ
On a statewide level, specifically through the Colorado Water Conservation Board, there is an effort to determine the exact influence that beaver structures have on streamflows.
Born said that would entail installing groundwater transducers and streamflow gauges before and after one of these restoration projects. That has never really occurred in the San Luis Valley before. The hope, he said, is to show that they are either increasing flows or doing very little.
The Valley Floor
Born said no one knows how many beavers live on the Valley floor. It would be a tough number to gauge. He thinks that there are far fewer beavers on the Valley floor than there are up in the national forest.
However, to give The Citizen an idea of just how often beaver conflicts occur, Born said that a farmer just a few miles upstream from Alamosa killed nearly 70 beavers in 2023. That number is normally around 30 to 40 a year.
โAlamosa proper might have a lot more beaver conflict if he wasnโt there. Ultimately, you have this philosophical issue of beavers are ecosystem engineers, we are the top ecosystem engineers. Beavers are pretty much number two. Which is really awesome. But we donโt like sharing.โ
There are ways to create cohabitation. One of those methods is through the use of a โbeaver deceiver.โ
The most common and most frustrating headache beavers cause is building dams up against culverts. Using hog panel fencing, about six or so feet offset from the culvert, the beavers would be able to build a dam around that fence but wouldnโt limit the ability of the culvert to pass water.
Beaver deceivers arenโt always successful, Born said. โThereโs always going to be a place for trapping and relocating.โ He said there are many more beavers on the Valley floor than they are able to deal with, meaning they have to be โpretty choosy.โ
That typically means establishing a priority list and going after the beavers giving people the most trouble and going after the largest colonies.
To do that, youโve got to have someone who knows how to humanely trap beavers. Their trapper, who works through the USDAโs Animal and Plant Health Inspection Service, works pretty much alone and often has to trap animals other than beavers โ like mountain lions, for example.
Because there is only one trapper, that priority list is important as the team doesnโt want to waste his time with beavers that arenโt quite a big enough problem.
Colorado Parks and Wildlife permits trapping beavers for this relocation program from June 1 to Sept. 1, but work doesnโt really kick off until closer to July. The team wants to make sure that the kits are grown enough to be able to survive and to make sure that mothers arenโt pregnant. Due to the Valleyโs limited window of warm days, it leaves about eight weeks to trap, quarantine, and release.

Beavers are good vectors. The Rio Grande Cutthroat trout is a threatened species and is currently seeing a resurgence in the Rio Grandeโs watersheds, but it is a sensitive species, particularly to Whirling Disease. When beavers are taken from one water source to another they have to be quarantined for three days and have their water changed every 24 hours to ensure they wonโt be carrying any diseases with them.
They are also quarantined to avoid the spread of Chytrid fungal disease, which affects amphibians.
All of these precautions are taking place because Reese and Born want to see these animals thrive and they want to ensure the health of the environment. Again, beavers are second only to humans in their ecosystem engineering. They are the waterโs guides, and despite their conflict with humans, are a keystone species that we would sorely miss.
What comes out of this program has yet to be seen, but itโs promising. Whatever data and answers can be drawn will be shared for years to come.
Even if the success rate is 30 to 50 percent and not every beaver released doesnโt make it, Reese said she still feels โlike the effort weโre putting in is worthwhile for the potential benefits of having more beaver on the landscape.โ

Workers breached the final dams on a key section of the Klamath River on Wednesday [August 28, 2024], clearing the way for salmon to swim freely through a major watershed near the California-Oregon border for the first time in more than a century as theย largest dam removal projectย in U.S. history nears completion. Crews used excavators to remove rock dams that have been diverting water upstream of twoย dams, Iron Gate and Copco No. 1, both of which were already almost completely removed. With each scoop, more and more river water was able to flow through the historic channel. The work has given salmon a passageway to key swaths of habitat just in time for the fall Chinook, or king salmon, spawning season.

Standing at Iron Gate Wednesday morning, Amy Bowers Cordalis, a Yurok tribal member and attorney for the tribe, cried as she watched water spill over the former dam and slowly flow back into the river. Bowers Cordalis has fought for the removal of the Klamath dams since 2002, when she saw some of the tens of thousands of salmon die in the river from a bacterial outbreak caused by low water and warm temperatures. She said watching the river return to its natural channel felt like she was witnessing its rebirth.
A hot summerย in Las Vegas pushed water consumption in August to the highest it has been all year, but the 2-year outlook for Lake Mead continues to improve. The U.S. Bureau of Reclamationโs 24-month study, updated each month with projections that guide how dams along the Colorado River are managed, shows continued stability for Lake Mead for the rest of the year and through 2025. Currently, Lake Mead is at 1,063.77 feet, about the same as it has been since mid-June, give or take a foot. Lake levels are expressed as feet above sea level โ altitude, not depth. Lake Mead is the nationโs largest reservoir, and itโs currently about 165 feet down from โfull poolโ level โ 1,229 feet. Itโs down to a third of its maximum capacity.
A chart shows Lake Meadโs levels from 2019 to present. The lake is currently at 1,063.77 feet.
Southern Nevada used 188,000 acre-feet of water in 2023. Thatโs far less than the stateโs allocation from the Colorado River. So far this year, use is at 157,872 acre-feet.

Beavers,ย Castor canadensisย in North America andย Castor fiberย in Eurasia, are widely referred to as nature’s engineers due to their ability to rapidly transform diverse landscapes into dynamic wetland ecosystems. Few other organisms exhibit the same level of control over local geomorphic, hydrologic, and ecological conditions. Though freshwater ecosystems are particularly vulnerable to changing climate, beavers and their wetland homes have persisted throughout the Northern Hemisphere during numerous prior periods of climatic change. Some research suggests that the need to create stable, climate-buffered habitats at high latitudes during the Miocene directly led to the evolution of dam construction. As we follow an unprecedented trajectory of anthropogenic warming, we have the unique opportunity to describe how beaver ecosystem engineering ameliorates climate change today. Here, we review how beavers create and maintain local hydroclimatic stability and influence larger-scale biophysical ecosystem processes in the context of past, present, and future climate change.
Jasper Reservoir, in the Indian Peaks Wilderness Area in Western Boulder County, has been sold under a set of covenants will ensure it waters are available to Middle Boulder Creek during the fall, when it is driest. Courtesy: The Colorado Water Trust
Ten years ago, an anonymous benefactor approached the Colorado Water Trust intent on providing it with an interesting gift: a reservoir high in the forests of the Indian Peaks Wilderness Area in western Boulder County.
The 23-year-old nonprofit was thrilled, understanding that the ultimate sale of the gift would insure its financial future, and making sure its mission to keep water in rivers continues.
The trust set to work immediately looking for a buyer who would agree to some very tough restrictions: permanent public access for fishing, hunting and camping, keeping the tiny reservoir full during the summer, and releasing the water down through Barker Reservoir in Nederland into Middle Boulder Creek during the fall, when the 37-mile stream segment is driest. Equally important is a conservation easement that prohibits any development of the water and land around the reservoir.
โThe covenants are quite strict,โ said Kate Ryan, the trustโs executive director. โWeโve taken away the development potential of the reservoir, so we had to have the right person come along.โ
The trustโs day job is to connect private water-right owners with threatened streams, helping set up financing and the legal agreements necessary to ensure the water can be transferred to the state, where it becomes part of the stateโs environmental program leaving water in streams that would otherwise be diverted.

If that sounds like a tall order, it often is. And finding a buyer for this reservoir would prove equally daunting. It turns out there arenโt a lot of people interested in buying covenant-restricted reservoirs, even in a water-short state such as Colorado.
But in August, the trust and Boulder Countyโs Tiefel family finalized the deal.
โThe trust wanted a partner to help manage the reservoir and run the water down Boulder Creek,โ said Doug Tiefel, a real estate developer whose family farms in eastern Boulder County and also has a small reservoir of its own. The family uses its reservoir to irrigate its operations and it leases any excess water to other growers in the area when water is available.
Tiefel said the Jasper Reservoir deal fit his familyโs water needs, and their environmental ethic.
โFor the ecosystem it is critical to keep more water in the river in late summer and early fall, and thatโs why we forged this partnership agreement,โ Tiefel said.
Prior to the sale, the reservoirโs water was often leased to other entities, such as the City of Boulder, which would in turn lease it to growers east of town. But the reservoir was managed differently every year. Under the Tiefelโs management plan, the water will flow more consistently, providing Middle Boulder Creek more certainty than it has had in the past, and a continuing supply of water for growers, Tiefel said.
Kim Hutton, the City of Boulderโs senior water resources manager, said the sale is a step forward for the entire Boulder Creek watershed, especially as climate change continues to reduce stream flows.
โThe benefit of this sale is to release water when stream flow is low, and that is complementary to what weโre doing,โ said Hutton, referring to the cityโs efforts to keep water in the creek system.
Ryan hopes the deal will be the first of many in Colorado in which permanent protective easements can be placed on water. She said sheโs also grateful for the financial security it provides the nonprofit.
โThe revenue gives us the certainty for years to come that we will be able to add water back into Coloradoโs rivers and streams,โ she said.
On September 11, Francine became the third and strongest hurricane of the season to strike the U.S. Gulf Coast, following Beryl (in Texas) in early July and Debby (in Florida) in early August. Francine briefly achieved sustained winds near 100 mph while making landfall around 5 pm CDT in Louisianaโs Terrebonne Parish. Hurricane-force wind gusts (74 mph or higher) spread as far inland as New Orleans, where a gust to 78 mph was clocked at Louis Armstrong International Airport. Meanwhile in the Mississippi Delta, antecedent dryness minimized flooding, although rainfall topped 4 inches in many locations and localized wind gusts briefly topped 50 mph. As the former hurricane drifted farther inland, days of locally heavy showers led to pockets of flash flooding, extending as far east as Alabama and the Florida Panhandle. Less than a week later, on September 16, Potential Tropical Storm Eight moved ashore in northeastern South Carolina and delivered flooding rainfall (locally a foot or more) across southeastern North Carolina. By the morning of September 17, the end of this drought-monitoring period, much of North Carolina and portions of neighboring states had received significant rain. The remainder of the country largely experienced dry weather, leaving widespread soil moisture shortages across the Plains and Midwestโa classic late-summer and early-autumn flash drought. In the western U.S., a cooling trend was accompanied some rain and high-elevation snow, heaviest across the northern Rockies and environs. As the long-running Western heat wave subsided, late-season warmth replaced previously cool conditions across the Plains, Midwest, and Northeast. Nationally, nearly one-half (46%) of the rangeland and pastures were rated in very poor to poor condition on September 15, according to the U.S. Department of Agriculture, up from an early-summer minimum of 19%…
Warm, mostly dry weather led to general expansion of abnormal dryness (D0) and various drought categories. Across the six-state region, topsoil moisture rated very short to short on September 15 ranged from 30% in North Dakota to 80% in Wyoming. In fact, values were above 50% in all states, except North Dakota. Some of the worst conditionsโextreme drought (D3)โexisted across northeastern Wyoming and southeastern Montana, an area still recovering from last monthโs Remington and House Draw Fires, which collectively burned across more than 370,000 acres of vegetation, including rangeland. Wyoming led the region on September 15 with 70% of its rangeland and pastures rated very poor to poor, followed by Nebraska at 45% and South Dakota at 42%…

Despite widespread precipitation in the northern Rockies and environs, only slight drought improvement was introduced, as concerns related to poor vegetation health and water-supply shortages were ongoing. In one piece of good news, however, a summer-long Western heat wave effectively ended. On September 17, the maximum temperature of 93ยฐF in Phoenix, Arizona, halted a record-setting, 113-day streak (May 27 โ September 16) with afternoon readings of 100ยฐF or greater. Given the turn toward cooler weather and the gradual increase in cool-season precipitation, the wildfire threat has diminished in some areas. In southern California, however, the Airport, Bridge, and Line Fires collectively burned more than 115,000 acres of vegetation earlier this month. On September 15, topsoil moisture in agricultural regions ranged from 54 to 80% very short to short in eight of eleven Western Statesโall but California, Arizona, and Utah. Similarly, rangeland and pastures were rated 40 to 70% very poor to poor in eight Western Statesโall but California, Utah, and Colorado…
Hurricane Francine delivered heavy rain across much of Mississippi, as well as parts of Arkansas, Louisiana, and Tennessee. On September 11, daily-record totals included 7.33 inches in New Orleans, Louisiana, and 4.14 inches in Gulfport, Mississippi. For New Orleans, it was the second-wettest September day on record, behind only 7.52 inches on September 25, 2002. On September 12, Apalachicola, Florida, received a daily-record sum of 6.29 inches, helping to boost the 3-day (September 11-13) total to 12.77 inches. Elsewhere on the 12th, daily-record totals reached 4.22 inches in Memphis, Tennessee; 3.95 inches in Jonesboro, Arkansas; and 3.05 inches in Tupelo, Mississippi. By September 13, rain loosely associated with the remnants of Francine spread as far east as Georgia, where Columbus collected a daily-record total of 3.22 inches. In Alabama, daily-record amounts for September 14 totaled 4.72 inches in Muscle Shoals and 3.63 inches in Birmingham. A separate area of heavy rain, prior to Francineโs arrival, soaked a small geographic area in southeastern Oklahoma, northeastern Texas, and southwestern Arkansas. However, areas outside the range of these downpours largely experienced worsening drought conditions. On September 15, Oklahoma led the region with topsoil moisture rated 61% very short to short, followed by Texas at 54%. Meanwhile, Texas led the region with rangeland and pastures rated 48% very poor to poor, followed by Oklahoma at 35%. On that date, Texas led the country with 36% of its cotton rated very poor to poor, well above the national value of 26%. Several patches of extreme drought (D3) continued to affect key agricultural regions of both Oklahoma and Texas. In Texasโ northern panhandle, record-setting highs for September 13 included 102ยฐF in Borger and 101ยฐF in Amarillo. For Amarillo, it was the latest triple-digit reading on record, supplanting 101ยฐF on September 11, 1910. Both Borger (101ยฐF) and Amarillo (100ยฐF) logged triple-digit, daily-record highs again on September 14. Meanwhile, Texas led the region with rangeland and pastures rated 48% very poor to poor, followed by Oklahoma at 35%.

Looking Ahead
During the next 5 days, active weather across the nationโs mid-section could lead to significant precipitation in from the central sections of the Rockies and Plains into the upper Midwest. While rain could slow agricultural fieldwork, including harvest activities, rangeland, pastures, and recently planted winter wheat will benefit from a boost in topsoil moisture. In contrast, generally dry weather will prevail across the remainder of the country, excluding the Atlantic Coast States. However, the western Caribbean Sea will need to be monitored for tropical cyclone development, with possible future implications for the eastern U.S.
The NWS 6- to 10-day outlook for September 24-28 calls for of near- or above-normal temperatures nationwide, with the West, North, and southern Texas having the greatest likelihood of experiencing warmer-than-normal weather. Meanwhile, near- or below-normal precipitation across the western and north-central U.S., as well as northern New England, should contrast with wetter-than-normal conditions from the central and southern Plains to the Atlantic Coast, extending as far north as the Ohio Valley and southern New England.

On April 16, 2024, the Yorba Linda Water District (YLWD/District) Board of Directors rededicated its state-of-the art PFAS Water Treatment Plant in honor of former YLWD Board President Dr. J. Wayne Miller. The J. Wayne Miller, Ph.D. Water Treatment Plant โ capable of treating up to 25 million gallons of water per day โ provides clean drinking water for the 80,000 customers the Yorba Linda Water District serves. Credit: Yorba Linda Water District
…in the past few years, Yorba Linda has picked up another distinction: Itโs home toย the nationโs largestย per- and polyfluoroalkyl (PFAS) water treatment plant of its kind, according to the city.
โThis December will be [three] years we’ve been running, and weโre the largest PFAS treatment plant using resin,โ saysย J. Wayne Miller, former board president at the Yorba Linda Water District, for whom the plant is named.
The Yorba Linda PFAS treatment plant took over a long, narrow strip of the water districtโs parking lot, not quite the length of a football field. A series of giant tanks sit atop a concrete platform. โHonestly, they look like large propane cylinders,โ says Todd Colvin, chief water system operator for the district. Each tank looms about 10 feet tall and can hold around 4,500 gallons. There are 22 of them, arranged in a double row, painted pristine ivory white. The tanks are packed half-full with a kind of resin โ special polymer beads โ that pull PFAS out of the water. Every gallon of water pumped from the districtโs wells now passes through a few of these tanks for treatment, before going to the homes and businesses of 80,000 people.
The Yorba Linda Water District built the largest PFAS water treatment plant of its kind because it had a big PFAS problem. In February 2020, the water district had to take all of its wells offline because they were drawing groundwater contaminated with PFAS…But where is all this PFAS coming from? In Orange County, one of the primary culprits appears to be the Santa Ana River Almost a hundred miles long, the Santa Ana River flows through mountains and canyons, the cities and suburbs of San Bernardino and Riverside. Along the way, it picks up PFAS. โWe find it in some of just the natural runoff that goes into the river during the winter, during storms,โ saysย Jason Dadakis, executive director of water quality and technical resources at the Orange County Water District. โWe also detect some PFAS coming out of the sewage treatment plants upstream.โ Thereโs also the legacy of factories and military bases in the area.

The city of Aspen wants to add a second turbine and generator unit to its hydroelectric plant at the base of Ruedi Dam, which officials say will allow for more power generation during times of high and low flows.
Officials say an additional turbine, which is estimated to cost about $4.6 million, will restore the plantโs power production capacity to its originally intended 5 megawatts and allow the city to maintain its renewable energy goals. Since 2012, increased releases from Ruedi to benefit downstream endangered fish have meant that late summer and early fall flows are too high for the existing turbine to operate efficiently.
Adding another turbine requires amending Aspenโs license for the Ruedi facility with the Federal Energy Regulatory Commission. According to the cityโs draft FERC application for an amendment posted on the Aspen Community Voice website, which officials say they plan on filing by the end of the month, the timing and amount of water released from Ruedi Reservoir has changed since the hydro project began operating in 1986. Power production has diminished in recent years to just 68% of what was originally intended.
Hydroelectric Dam
โAfter 40 years of reservoir and hydroelectric operations, it is now clear that achieving power output (maximum capacity and energy values) that approximates the original level authorized under the license will require additional generation equipment,โ the application reads.

The facility is most efficient at flows between 100 and 225 cfs. But summer and fall flows are often higher than this range and winter flows often lower. Aspen has no control over how much water is released from the reservoir, which is managed by the U.S. Bureau of Reclamation.
According to the cityโs application, gross energy production has declined from an average of 18.5 million kilowatt hours annually from 1986 to 2004 to 15 million kWh over the last decade.
โThe equipment is kind of mismatched for whatโs going on with those releases,โ said Phil Overeynder, utilities engineer for the city of Aspen. โSo weโre losing all of that energy above 225 cfs. If we have an additional turbine, weโll be able to hit the sweet spot for the releases and generate the full amount of energy when itโs available.โ
Also, an error in the design of the powerplant introduces air into the water column, reducing the efficiency of the turbine. Because of this flawed design, the hydro plant canโt efficiently make power above about 225 cfs. The city looked at options to fix this problem, Overeynder said, including raising the floor of the building, but the least expensive solution is adding another turbine.
A new turbine would be rated for 1.2 megawatts of production and the original turbine would be downgraded to a 3.8 megawatt capacity, for a total of 5 megawatts โ the same as the plantโs current rating, but split between two turbines. During periods of higher releases, about 230 cfs would be routed through the existing turbine and 70 cfs would be routed through the new turbine for about 92% efficiency.
The project would also upgrade the hydro plant so it can be operated remotely, and would let the city continue making hydropower with one turbine if the other one is down for maintenance. The total project cost including the new turbine would be around $8.6 million, according to Overeynder.
โThe proposed second turbine at Ruedi, together with other planned actions, will enable Aspen to restore the balanced power supply, which will maintain grid reliability and resiliency while continuing to provide 100% renewable energy,โ the application reads.

Fish flow
Releases out of Ruedi have changed since the hydro plant began operating, with the reservoir now one of the most important sources of water for the Colorado River Endangered Fish Recovery Program. The program, designed to get water into a chronically de-watered section of the Colorado River near Grand Junction known as the 15-mile reach, has about 15,000 acre-feet of water available most years in Ruedi. Entities that own water in Ruedi such as Garfield County, Caerus Energy, Grand Junction area water provider Ute Water and the Colorado River Water Conservation District have also in recent years leased their water to the recovery program to boost flows beyond the dedicated 15,000 acre-foot pool.
All of the recovery programโs releases are made in July through October, when streamflows naturally are reduced, but irrigation demands in the Grand Valley leave diminished river levels for endangered fish. According to numbers provided by recovery program staff, the Ruedi fish water releases increased from an average of 18,586 acre-feet in the time period from 1998 to 2012, to 20,460 acre-feet in the time period of 2013-2023.
โRuedi is an essential piece of our ability to manage water for the endangered fish,โ said Juile Stahli, director of the Upper Colorado Endangered Fish Recovery Program. โRuedi has become really critical in helping us affect the ecology downstream.โ
According to Tim Miller, a hydrologist with the U.S. Bureau of Reclamation who manages Ruedi, the current reservoir release pattern โ higher flows in the late summer and lower flows in the winter โ began after 2012 when the water in the reservoir was fully contracted. The owners of this contracted water (like those mentioned above) release it when they need it, and many lease it to the recovery program. Because more contract water is released from Ruedi, Miller said he has to make up that loss to the reservoir by releasing less water over the winter, resulting in low winter flows.
โI can tell you with absolute certainty that since Ruedi has been fully contracted we have released more water for fish augmentation than we did since the program started,โ Miller said. โBecause weโve released more contract water, given an average fill, itโs going to take more water to fill the reservoir the next year. So my releases during the winter were lower to recover that.โ
According to data from USBR, the average flow out of the reservoir from July to October before the endangered fish recovery program started from 1980 to 1997 was 180 cfs. The average release after the program began in 1998 has been 204 cfs. The number of days releases have exceeded 225 cfs has also been trending upward since the recovery program began.
Aspenโs 100% renewable energy goals
Aspen first achieved its goal of 100% renewable energy in 2015, when a project that retrofit the Ridgway Reservoir dam in the Uncompahgre River basin to generate hydroelectric power came online. The city of Aspen was integral in launching the project, funding a feasibility study in the early 2000s and signing a 10-year contract in 2012 to purchase about 10 million kwh a year from Ridgway once it became available. Ridgway now accounts for about one-seventh of Aspenโs total power portfolio, according to Overeynder. In an effort to continue meeting its 100% renewable goal, the city is also looking to continue and potentially expand its hydroelectric power generation capacity on Maroon Creek.
Aspen has begun the process of relicensing the project with FERC, which is smaller than the Ruedi project and has a capacity of 450 kilowatts. Aspen is also proposing to add additional units on Maroon Creek for a total of 500 kw.
Hydropower, including energy Aspen buys from projects at Ridgway Reservoir and Western Area Power Administration, is supposed to make up about 45% of the cityโs energy portfolio. But that percentage has dropped with the declining power production at Ruedi in recent years. The city also buys wind and solar power to achieve 100% renewable energy.
โIf we do this (project at Ruedi) plus what we did already at Ridgway and are proposing to do at Maroon Creek, we will get back up to that 45%,โ said Justin Forman, Aspenโs Utilities Director. โFor us, every megawatt counts and if itโs something local like this, weโre super proud of it and it certainly fits into the values that we have.โ
The FERC relicensing process will take several years, with sign-offs also needed from the Colorado Department of Public Health and Environment, the U.S. Army Corps of Engineers and Pitkin County. Overeynder expects the new turbine to be operating sometime in 2027.

The U.S. Forest Service has finalized a land exchange with Mt. Emmons Mining Company located in Gunnison and Saguache counties.
Under the agreement, finalized on Aug. 29, the Forest Service exchanged 539 acres of federal land located adjacent to the Keystone Mine for 625 acres of land owned by Mt. Emmons Mining Company located within the Grand Mesa, Uncompahgre and Gunnison National Forests and Rio Grande National Forest.
Iron Fen. Photo credit from report “A Preliminary Evaluation of Seasonal Water Levels Necessary to Sustain Mount Emmons Fen: Grand Mesa, Uncompahgre and Gunnison National Forests,” David J. Cooper, Ph.D, December 2003.
The land exchange allows the Forest Service to improve wildlife habitat and recreation opportunities by reducing private inholdings and creating more contiguous public land. The parcels acquired by the Forest Service include riparian and wet meadow habitats, which are vital to various bird and aquatic species.
Additional benefits of the land exchange include an established Conservation Easement and Mineral Extinguishment Agreement, prohibiting mining and allowing for non-motorized recreation in the future. It allows Mt. Emmons Mining Company to address mining remediation efforts, including water quality and facilitated the transfer of ownership and administration of the Kebler Winter Trailhead to Gunnison County.
โWe are pleased to see this momentous exchange finalized,โ said Dayle Funka, Gunnison district ranger. โThis project was truly a collaborative effort with local non-profits, private landowners and local and federal governments working to benefit future generations. We encountered obstacles throughout the process but found ways to move forward in the spirit of collaboration. As a result of many peopleโs dedication and perseverance, this land exchange will enhance public access and enable future non-motorized recreational opportunities. I commend the Mt. Emmons Mining Company for their commitment to mining remediation efforts and water quality, while honoring the values of the community.โ
Q: Do you believe that climate change is largely driven by human activity, including the burning of fossil fuels? If not, is there a different cause you would cite?
A:ย Harris calls climate change an existential threat and says the United States needs to act urgently to address it. As a presidential candidate in 2019, she released a $10 trillion climate plan that calls for investing in renewable energy, holding polluters accountable, helping communities affected by climate change and protecting natural resources. As California attorney general, she prosecuted oil companies for environmental violations. As vice president, she was the tie-breaking vote in the Senate for the Inflation Reduction Act, which provided about $370 billion to reduce greenhouse gas emissions to 40 percent below their 2005 levels by the end of this decade.
A:ย Trump believes human activity is just one cause of climate change, not necessarily the dominant factor. Pressed in a 2020 debate about whether human pollution contributes to warming, Trump said, โI think a lot of things do, but I think to an extent, yes.โ Trump told The Washington Postโs editorial board in 2016 that he is โnot a great believer in man-made climate change.โ He has also long rejected climate science, sometimes calling global warming a โhoax.โ
Q:ย Do you believe climate change is making disasters such as hurricanes, wildfires and heat waves more intense?
A:ย Harris has said the United States must take action to fight climate change in the face of increasing drought, floods, hurricanes, wildfires and sea level rise. As vice president, Harris announced more than $1 billion in grants in 2022 for states to address flooding and extreme heat exacerbated by climate change. โThe frequency has accelerated in a relatively short period of time,โ she said. โThe science is clear. Extreme weather will only get worse, and the climate crisis will only accelerate.โ’
A:ย At a rally in March 2022, Trump mocked the threat posed by sea-level rise and the nationโs concern with combating climate change. โAnd yet you have people like John Kerry worrying about the climate! The climate!โ Trump said. โOh, I heard that the other day. Here we are, [Russian President Vladimir Putin is] threatening us [and] heโs worried about the ocean will rise one-hundredth of one percent over the next 300 f—inโ years.โ In 2019, Trump also exclusively blamed forest mismanagement for more destructive and deadly wildfires, rather than climate change. Scientists have said that no amount of forest management can stop wildfires in a more flammable world.

About 20 people attended the event. They heard the panelists discuss Florida and Animas river trends, how Southwest Coloradoโs climate is changing over time and fast facts about where Durangoโs water comes from. Pool said Durangoโs water comes predominantly from the Florida River and is supplemented by the Animas River. The city uses about 1.5 billion gallons of water per year for all utility use types, he said…He said both the Florida and Animas rivers are trending downward in total water volume; in dry years, groundwater recedes, which affects the total amount of surface water available. But Durangoโs water consumption has remained flat despite a growing population, he said.
โPer capita, water use is going down. Total water use is staying pretty flat, with some seasonal fluctuations due to irrigation,โ [Marty Pool] said.
While the city uses all the water from the Florida River it has legal rights to every year, itโs not even approaching the maximum usage of water from the Animas River, he said…Durango is lucky in that not all communities have that many second or third water options, he said.

September 16, 2024
SALT LAKE CITYโGreat Salt Lake will benefit from 10,000 additional acre-feet of water thanks to a partnership between the National Audubon Society and The Nature Conservancyโas co-managers of the Great Salt Lake Watershed Enhancement Trustโin partnership with Jordan Valley Water Conservancy District, the Church of Jesus Christ of Latter-day Saints, the Utah Division of Wildlife Resources, and the Utah Division of Forestry, Fire and State Lands. The water will be delivered from upstream storage in Utah Lake, and flow through the Jordan River to Great Salt Lakeโs Farmington and Gilbert Bays through mid-October.
Jordan Valley Water Conservancy District (Jordan Valley Water) is donating 5,300 acre-feet of water, the Church of Jesus Christ of Latter-day Saints (Church) is donating 1,700 acre-feet of water, and the Great Salt Lake Watershed Enhancement Trust (the Trust) is leasing 3,000 acre-feet of water, with all water sourced from Welby Jacob Water Users Company shares. The Utah Divisions of Wildlife Resources (DWR) and Forestry, Fire and State Lands (FFSL) will place the water to beneficial use at Great Salt Lake.
โDelivering new water to Great Salt Lake is essential to preserve the health of the lake and Utah communities, as well as protect the habitats for millions of birds that rely on it,โ said Marcelle Shoop, Executive Director of the Trust and National Audubon Societyโs Saline Lakes Director. โWe are grateful for the vision and commitment of many partners, for this innovative late season water release to diversify benefits to the lake and its wetlands, as well as the Jordan River. We look forward to future opportunities to repeat these efforts in years to come.โ
While the 2024 spring season flows increased Great Salt Lake water levels, ongoing flows are needed to reach healthy levels. Now the lake will receive additional flows this fall through this key collaboration.
โThis release to Great Salt Lake is made possible by four key factors: water conservation efforts of residents and businesses in Salt Lake Valley, important changes to water rights laws adopted by the legislature over the last few years, Jordan Valleyโs effective use of its existing water storage and conveyance infrastructure, and a strong snowpack,โ says Alan Packard, General Manager of Jordan Valley Water.
Migrating shorebirds, waterfowl and other waterbirds will benefit as their habitats receive these additional flows. Increased water flows to the lake can also aid with salinity management in the South Arm, and in some cases improve capacity to control the spread of botulism and other diseases.
โAdditional flows late in the water season are particularly beneficial during dry, warm conditions when there are risks of avian botulism,โ DWR Director J Shirley said. โOver 12 million birds, represented by 339 species, utilize the Great Salt Lake and its associated wetlands. The ecosystem that the Great Salt Lake and its wetlands provide is crucial for these birds, and we applaud the ongoing efforts to conserve these habitat areas and the lake.โ
The release will take place during Jordan River Commissionโs Get To the River Festival, highlighting that in addition to the benefits to Great Salt Lake, these flows will benefit Jordan River and bordering communities, ecologically and recreationally, as the water moves down some 51 river miles.
โThe Church continues to look for ways to care for the Great Salt Lake and the ecosystem that depends on it. This latest donation is another step in that effort. We consider it a divine responsibility to care for the earth and be wise stewards of Godโs creation,โ said Bishop W. Christopher Waddell, First Counselor in the Presiding Bishopric, The Church of Jesus Christ of Latter-day Saints.
On September 3, 2024 the board of the Pagosa Springs Sanitation General Improve- ment District (PSSGID) voted to move $500,000 from town funds to kick-start critical repairs on its sewer system, pushing off a bigger decision on financing for a larger overhaul of the system. Public Works Director Karl Johnson said that he fears a โcatastrophic eventโ could be in the cards if the district doesnโt do something now to shore up the system.
Town Manager David Harris added, โWe need to get moving here … and we need to move sooner rather than later.โ
Johnson explained to the board that the biggest project on the districtโs radar would be to continue repairing what has been deemed category 4 and 5 problems with sewer pipes, as well as its obligation to upgrade the Vista Treatment Plant, owned and operated by the Pagosa Area Water and Sanitation District (PAWSD), to bring it into compliance with state Regulation 85.
From email from the Reclamation Western Colorado Area Office:
With a wetter weather pattern and increasing forecast flows downstream, the Bureau of Reclamation has scheduled a decrease in the release from Navajo Dam from 800 cubic feet per second (cfs) to 700 cfs for Tuesday, September 17th, at 4:00 AM.
Releases are made for the authorized purposes of the Navajo Unit, and to attempt to maintain a target base flow through the endangered fish critical habitat reach of the San Juan River (Farmington to Lake Powell). The San Juan River Basin Recovery Implementation Program recommends a target base flow of between 500 cfs and 1,000 cfs through the critical habitat area. The target base flow is calculated as the weekly average of gaged flows throughout the critical habitat area from Farmington to Lake Powell.
This scheduled release change is subject to changes in river flows and weather conditions. If you have any questions, please reply to this message, call 970-385-6560, or visit Reclamationโs Navajo Dam website at https://www.usbr.gov/uc/water/crsp/cs/nvd.html.
States, Native American tribes and local communities could get help accessing federal funds for water infrastructure projects in drought-stricken areas under new U.S. Senate legislation.
The Water Project Navigators Act โ sponsored by U.S. Sens. Jerry Moran and John Hickenlooper and Reps. Brittany Pettersen and Juan Ciscomani โ would create a program in the Bureau of Reclamation to place โnavigatorโ positions in local, state and tribal communities. Navigators would help connect communities to resources.
In a news release announcing the legislation, Moran, a Kansas Republican, said federal resources to help preserve water can be difficult to access.
โWidespread drought is impacting many communities across Kansas, hurting family farms, local municipalities and businesses,โ Moran said.
Hickenlooper, a Colorado Democrat, said the same.
โRural and Tribal communities deserve their fair share of federal funds to address drought, but all too often are left out,โ Hickenlooper said.
Fellow Coloradoan Pettersen said water scarcity is felt throughout Colorado, but rural communities struggle to respond.
โIt is critical that we invest in these areas to strengthen and protect our water resources and help communities draw down federal dollars,โ Pettersen said.
Kansas and Colorado โ along with Ciscomaniโs home state of Arizona โ struggle with continual drought and limited access to water. As of last week, according to the U.S. Drought Monitor, more than 51% of Kansas is in some level of drought, mostly moderate or severe. Almost 5% of Arizona is in extreme drought. Colorado is currently the least affected with about 12% of the state in some level of drought.
โIn Arizona, water is our most precious resource,โ said Ciscomani, a Republican. โAs the drought worsens in the West, it is now more important than ever that impacted communities have the necessary tools to secure federal dollars for critical multi-benefit water infrastructure projects.โ
The legislation is backed by conservation groups, according to the news release, along with the Kansas Water Office, Kansas Department of Health and Environment and the Kansas Department of Agriculture.

โItโs absolutely everywhere,โ said Sarah Hale, an environmental researcher who manages ZeroPM, a project funded by the European Union. โTrifluoroacetic acid (TFA) will be the next discussion in America, I can guarantee it. It will be about how should we treat it and what should we do.โ
The attention on TFA underscores the game of whack-a-mole that scientists and communities face with forever chemicals. With thousands of identified versions of the substances, the chemicals are practically ubiquitous in the global economy, and researchers are still determining the exact health risks associated with many of them. But TFA could pose a particularly difficult problem down the line, due to how much it would cost to take it out of drinking water, experts say. The substance is extremely small, mobile and water soluble. As a result, it cannot be removed from water using the filtration systems that many communities are installing now for large, widely studied forever chemicals, said Rainer Lohmann, a professor of oceanography at the University of Rhode Island.
Trifluoroacetic acid (TFA) is a very persistent contaminant that has gained attention due to its multitude of anthropogenic sources, widespread occurrence in the environment, and expected accumulation in (semi-)closed drinking water cycles. Here, we summarize and assess the current knowledge on the anthropogenic sources of TFA to better understand the human-induced environmental TFA burden and highlight future research needs. Formation of TFA from the degradation of volatile precursors leads to diffuse and ubiquitous contamination of the environment. The analyses of ice core and archived leaf records have undoubtedly demonstrated that atmospheric depositions of TFA have increased considerably over the last decades in the Northern Hemisphere. Moreover, many point sources of TFA have been identified, which can lead to contamination hotspots posing a potential threat to human and environmental health. Also, unintentional formation of TFA during per- and polyfluoroalkyl substance (PFAS) remediation might become a major secondary source of TFA.

The tropical Pacific is still in neutral, but nature continues giving us signs that La Niรฑa is on the way, and our La Niรฑa Watch remains. Forecasters estimate a 71% chance that La Niรฑa will emerge during SeptemberโNovember and expect it will persist through the Northern Hemisphere winter. A weak La Niรฑa is the most likely scenario.
Opening credits
While there are no plot twists since Tomโs August postโfrequent readers could be forgiven for fast-forwarding this monthโs updateโthat 71% chance of La Niรฑa developing this autumn is a small upward tick. Also, the slower-than-expected development of La Niรฑa is a great example of how the short-term (subseasonal) and very long-term (climate change) complicate seasonal outlooks. Iโll run the numbers in a minute, after a word from our sponsor.
Hello folks! Do you wish you could get a heads-up about what your winter rain, snow, and temperature conditions might be like? Ask your forecaster about ENSO, the El Niรฑo/Southern Oscillation! This seasonal climate phenomenon is made from the surface temperature of the tropical Pacific, including warmer-than-average water (El Niรฑo) and cooler-than-average water (La Niรฑa), and can be predicted months in advance. ENSO changes global atmospheric circulation in known ways; common side-effects may include shifts in the jet stream and changes in global temperature and precipitation patterns, droughts, and heatwaves.
Back to our regularly scheduled program
ENSO forecasters get their information from two general areas: climate prediction models and current observed conditions in the ocean and atmosphere. Climate models are up first, today. (See footnote.)
Line graph showing observed and predicted temperatures (black line) in the key ENSO-monitoring region of the tropical Pacific from early 2024 though spring 2025. The gray shading shows the range of temperatures predicted by individual models that are part of the North American Multi Model Ensemble (NMME, for short). Most of the shading appears below the dashed blue line by the fall, meaning most models predict that temperature in the Niรฑo-3.4 region of the tropical Pacific will be cooler than average by at least 0.5 degrees Celsius (0.9 degrees Fahrenheit)โthe La Niรฑa threshold. NOAA Climate.gov image, based on data provided by Climate Prediction Center.
The North American Multi-Model Ensemble (NMME) is a collection of computer models that take information about current global conditions and apply physical equations to make predictions about upcoming weather and climate. For more about the NMME, check out this ENSO Blog post and this recent one from our friends at Seasoned Chaos.
This set of climate models has been predicting the development of La Niรฑa since last winter, and continues to do so, although itโs taking a little longer than initially expected. This isnโt particularly surprising, since predictions made in the spring are often less accurate than predictions made at other times of the year. Overall, though, the modelsโ prediction of La Niรฑa this upcoming winter has been consistent, including from last month to this month, providing continued confidence in the forecast despite the slowdown.
Reality TV
Time to check in with a few of our favorite characters. Our primary metric for ENSO, the surface temperature of the tropical Pacific Ocean in the Niรฑo-3.4 region, was about 0.1 ยฐC cooler than the long-term average (long-term = 1991โ2020) in August, according to the ERSSTv5 dataset. This is solidly neutralโthe La Niรฑa threshold is 0.5 ยฐC cooler than averageโand only a small drop from July.

Five of the eight gray lines dip below the dashed blue line (the La Niรฑa threshold) in the winter following the El Niรฑo. The 2023-24 event appears headed in the same direction. Graph by Emily Becker based on monthly Niรฑo-3.4 index data from CPC using ERSSTv5.
The winds over the tropical Pacific play an important role in ENSOโs dramatic arc. When the near-surface winds in the tropicsโthe trade windsโare stronger, they cool the surface and keep warmer water piled up in the far western Pacific. They can also trigger an upwellingย Kelvin wave, an area of cooler-than-average water under the surface that moves from west to east. Throughout August, the trade winds were stronger than average across most of the tropical Pacific, helping to maintain the gradual surface cooling tendency and to bolster the amount of cooler water under the surface. This cooler subsurface water will provide a source to the surface over the next few months.
Beneath the surface of the tropical Pacific Ocean at the equator, a deep pool of cooler-than-average (blue) waters has been building up over the past couple of months (July 12โSept. 5, 2024). This pool of relatively cool water is a key factor behind the prediction for La Niรฑa later this fall and winter. NOAA Climate.gov image, based on analysis from Michelle L’Heureux, Climate Prediction Center.
Character development
We started this La Niรฑa Watch party back in February. Looking back at that forecast, the probability of La Niรฑa developing by JuneโAugust was about 55%, with about a 42% chance of ENSO-neutral during that period. These probabilities mean that La Niรฑaโs development in JuneโAugust was favored, but there was still a good chance that neutral would linger. As it turned out, the JuneโAugust average sea surface temperature in the Niรฑo-3.4 region, the โOceanic Niรฑo Index,โ was 0.1 ยฐC below average, in the neutral range.
So why is La Niรฑa behind schedule? Honestly, nature is wild and crazy and it amazes me that we can predict anything ever, especially many months in advance. In this case, though, there are a couple of complicating factors we can point to. The first is our old frenemy, short-term variability, or, essentially, unpredictable weather events that complicate seasonal or longer predictions. For example, just a few periods of weaker trade winds can delay surface cooling. Unfortunately, predicting such short-term variations is an ongoing challenge, and currently we can only predict these trade wind fluctuations a week or so in advance.
On the other side of the timeline, we have climate change. The global ocean temperatures are still way above average, and they are predicted to drop only slightly over the next several months. We donโt yet have a clear picture of how global warming may affect ENSO in general, or the development of La Niรฑa this year in specific.
Coming up on La Niรฑa Watch
That said, the most likely outcome is still that La Niรฑa will be in place this winter, with slightly greater than 80% chance of La Niรฑa in NovemberโJanuary, probably a weaker event (see strength probabilitiesย here).
Out of the three climate possibilitiesโLa Niรฑa, El Niรฑo, and neutralโforecasts say that neutral conditions are the most likely for the AugustโOctober season (tall gray bar above the ASO label, slightly over 60 percent chance). By the September-November (SON) season, La Niรฑa has the highest chance of occurring (blue bar, 71 percent chance). NOAA Climate Prediction Center image.
A weak La Niรฑa wouldnโt play as large a part in steering global atmospheric circulation patterns, meaning a lower chance of La Niรฑaโs typical impacts on winter conditions. However, even a weak La Niรฑa can nudge the winter climate and would likely factor into CPCโs winter outlook.
Stay tuned here for recaps and predictions about your favorite program, ENSO!
Footnote
There are two kinds of prediction models, dynamical and statistical. The model information I discuss in this post is from dynamical models. Statistical models use historical observations and their relationships to predict how conditions might evolve. Statistical models do not use physical equations, but rather statistical formulations that produce forecasts based on a long history of past observations of sea surface temperature, atmospheric pressure, subsurface temperature, and others. Statistical models have been around longer than dynamical models, because the dynamical ones require high performance computers.
“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 โholeโ 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 donโt 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

โWe will have less water. Forever,โ Rice said. โWe have to accept that and โฆ it’s up to us to be more efficient.โ
Thatโs why Rice applied for funding from Utahโs Agricultural Water Optimization Program โ a big money push to help farmers and ranchers modernize their irrigation. With roughly three-fourths of the stateโs water going to agriculture, the situation has put a bullseye on farming when it comes to stretching that H20. Utah is counting on the program โ which covers half the cost of buying new, more efficient gear โ to save more water for communities, rivers and reservoirs downstream.
As he stood next to a center pivot irrigation system the program helped pay for, Rice reached for one of the dozens of spray nozzles that dangle a few feet over the ground. Compared to the equipment it replaced, he said, the difference is night and day.
โIf hundreds of farms can save millions of gallons of water, I mean, we can fix it. โฆ And do I feel like we have a responsibility to do that? Yeah, hell yeah.โ — [Andy Rice]
Thatโs the idea behind Utahโs optimization program. If state money lowers the financial barrier for farmers to upgrade, the water savings might add up to help Utah maximize the little moisture it has…
Rice is just one example of the stateโs approved projects, 551 of them and counting, said Program Manager Hannah Freeze, since the program began in 2019. The Utah Legislature has allocated $276 million so far and $108 million has gone to approved projects. A majority of that money is flowing toward the Great Salt Lake โ $23 million has been approved for 112 projects in Utahโs Colorado River Basin. Itโs a good start, Freeze said, but a drop in the bucket compared to what it might take to significantly improve Utahโs water outlook.
โIf we were going to make a real dent or reach the majority of the farmers that we have, it’s more like a $2 billion number.โ

A Front Range water distributor is pushing back on a planned transfer of rights to water from the Colorado River. It has led to a disagreement between two major water agencies โ a minor flare-up of longstanding tensions between Eastern Colorado and Western Colorado, which have anxiously monitored each othersโ water usage for decades.
Northern Water, which serves cities and farms from Fort Collins to Broomfield, is asking for more data about the future of the Shoshone water right. Meanwhile, the Colorado River District, a powerful taxpayer-funded agency founded to keep water flowing to the cities and farms of Western Colorado, says Northern Water may be attempting to stymie its purchase of the water rights.
In early 2024, The Colorado River District announced it would spend nearly $100 million to buy rights to the water that flows through the Shoshone power plant, near Glenwood Springs. Shoshoneโs water right is one of the oldest and biggest in the state, giving it preemptive power over many other rights in Colorado.

Even in dry times, when water shortages hit other parts of the state, the Shoshone power plant can send water through its turbines. And when that water exits the turbines and re-enters the Colorado River, it keeps flowing for a variety of users downstream.
Since that announcement, the river district has rallied more than $15 million from Western Colorado cities and counties that could stand to benefit from the water right changing hands. Those governments are dishing out taxpayer money in hopes of helping make sure that water stays flowing to their region, even if demand for water goes up in other parts of the state.
The river district plans to leave Shoshoneโs water flowing through the Colorado River. Itโs an effort to help settle Western Coloradoโs long-held anxieties over competition with the water needs of the Front Range, where fast-growing cities and suburbs around Denver need more water to keep pace with development.
The water right is classified as โnon-consumptive,โ meaning every drop that enters the power plant is returned to the river. The river district wants to ensure the water that flows into the hydroelectric plant also flows downstream to farmers, fish and homes. The agency plans to buy rights to Shoshone’s water and lease it back to the power company, Xcel Energy, as long as Xcel wants to keep producing hydropower.
Almost all of the $98.5 million for the river districtโs purchase of Shoshoneโs water will come from public funds. In addition to money from its own coffers and Western Colorado governments, the river district also plans to apply for federal funding to pay for its purchase of Shoshone’s water. It is planning to seek $40 million from the Inflation Reduction Act.
Despite decades-long tensions between water users on the Western Slope and the Front Range, leaders on the East side of the mountains have stayed mostly quiet about the Shoshone transfer.

Northern Waterโs recent statements about Shoshone perhaps mark the most notable public pushback to the pending deal. The agency supplies water to Front Range cities such as Loveland and Greeley, as well as farms along the South Platte River all the way to the Nebraska border.
The agency outlined its concerns in a letter to elected representatives, including Colorado Senators Michael Bennet and John Hickenlooper and congresspeople Joe Neguse, Lauren Boebert, Yadira Caraveo and Greg Lopez.
In short, Northern said it supports the concept of the transfer, but wants an independent study of how much water the Colorado River District plans to send down the river each year.
โWe want to make sure that we’re all going into this with the same data to make sure that everyone’s interests are being addressed,โ said Jeff Stahla, Northern Water spokesman.
Northern posits that the Western Slope could pull more water than the amount that has been historically used by Shoshone โ enough to increase strain on upstream reservoirs that also supply the Front Range.
The River District calls that claim a โgross mischaracterizationโ of its plans.
“Their points ignore the stated intent of the effort and are counter to the stated values,โ said Matthew Aboussie, a spokesman for the River District, โAnd they 100% know that.โ
The River District published its own letter about the matter. The agencyโs director said Northern Waterโs efforts โwere received as intentional obstacles intended to threaten the viability of the Shoshone Permanency Project,โ and said Northernโs calls for more data collection could require a time-intensive study of the project and tie it up in litigation for up to a decade.
โWe are not looking to change the historic flows,โ Aboussie said. โSo the intention is to protect the status quo.โ
The River District is currently compiling data about the history and future of the Shoshone water right and plans to present it in Coloradoโs water court, which is part of the stateโs normal process to approve the transfer or sale of water rights.
Four years after a high-profile dam restoration project was completed in the scenic headwaters of the Rio Grande, promises to deliver water for fish during the winter and other recreational benefits have not been met, environmental groups charge.
The Rio Grande Reservoir Project was funded by state loans and public grants provided by the Colorado Water Conservation Board, which often bases financing approvals, in part, on a projectโs ability to serve multiple purposes, including water for fish, habitat and kayakers.
โThe Colorado Water Conservation Board โฆ provided $30 million in the form of loans and grants to complete the project,โ the CWCB said In aย project updateย posted on its website. โBenefits include: instream flow enhancement; channel maintenance; outdoor recreation opportunities; terrestrial and aquatic wildlife habitat; irrigation, augmentation; and storage to comply with the Rio Grande Compact between Colorado, New Mexico, and Texas.โ
The public-private project was completed in 2020.
The CWCB declined an interview request for this story, but said in an email that there were no specific conditions in the loans and grants tied to providing environmental benefits.
โCWCB does not have the ability to impose extra terms on the recipients of funds that are not articulated in the funding agreements. In the case of the Rio Grande Reservoir Rehabilitation, the final deliverable was completion of the project,โ a spokesperson said.
Still Kevin Terry, southwest program director for Trout Unlimited, said the project would likely never have been funded without assurances that the dam would be operated differently to help the river, including releasing water in the winter to aid the fish and changing the time water is released throughout the summer to keep the river cooler and healthier during prime fishing and kayaking season.
โThere were lots of environmental benefits touted before the Colorado Water Conservation Board and the roundtable,โ Terry said, referring to the Rio Grande Basin Roundtable. The roundtable is one of nine public groups across the stateโs major river basins that help address local water issues and funnel state grants to projects they approve.
The San Luis Valley Irrigation District, which owns and operates the dam, serves farms around Center and has delivered water from the dam since 1912, according to its website. Neither District President Randall Palmgren nor Superintendent Robert Phillips responded to numerous requests for comment.
The district uses the reservoir to store water for irrigators. Trout Unlimited and others arenโt asking for any water, they say, just that existing water that would be released anyway be sent downstream at times that are beneficial to the river.
Screenshot from Google Maps
Among key complaints by environmentalists is that the irrigation company is not allowing water to flow out of the rehabilitated dam during the winter, something that would benefit young fish and allow them to grow larger for the next fishing season.
Terry said the irrigation district has said it canโt deliver that winter water because it is difficult to operate the new equipment in freezing winter weather. But Terry said he doesnโt understand how the project could have been built without the ability to deliver in cold weather, something that occurs routinely in other reservoirs in the valley.
Jim Loud, a Creede resident and avid angler who lives on the river, said he and others are tired of waiting for the river to receive the benefits many believed would have been delivered by now.
โAll we want is to get them to do what they said they were going to do,โ said Loud, citing numerous CWCB documents dating back several years outlining the environmental benefits of the project. Loud is part of the Committee for a Healthy Rio Grande.

The old days werenโt fun
The conflict comes as the Rio Grande Basin, which begins high above Creede and flows south to the Gulf of Mexico, continues to struggle with declining aquifer levels due to heavy agricultural use and low stream flows due to drought and climate change. In Colorado, the Rio Grande waters a potato industry that is one of the largest in the nation.

Creede local Dale Pizel, who owns a ranch on the river and caters to the fishing community, said river conditions have improved some since the dam was rebuilt. Prior to the project, the irrigation company would routinely dry up the river for weeks during the high summer tourist season to make repairs to the dam.
โThat doesnโt happen anymore,โ Pizel said. He too serves on the Rio Grande Basin Roundtable, which also approved some grants for the project.
โI voted for that project knowing it would have environmental benefits, and it did,โ Pizel said, because there is no need for the irrigators to dry up the river to repair a failing dam anymore.
Still, he said, if environmental promises are being made publicly, the state needs a better way to make sure they are kept.
Trout Unlimitedโs Terry said for years he was hopeful that the rehabilitated dam would serve as another multiuse storage project in the water-short valley helping farmers and the environment.
โWe are so disappointed in the delivery of what was promised and the lack of the CWCB holding the irrigation district accountable in any way,โ he said.
Altering the damโs new equipment so that winter releases can occur will likely require spending about $5 million, according to Terry.
Pizel and others hope a resolution between the farmers and the environmentalists can occur without legal action.
โWe donโt want to start thumping each other in the chest,โ Pizel said. โThatโs the way it was in the old days. It was not fun.โ

This Week’s Drought Summary
There was a sharp difference in temperatures across the U.S. this week (Sep. 3 to Sep. 10). Temperatures in the West were above normal, whereas areas from Texas to Wisconsin and east saw temperatures of 3 to 9 degrees below normal. Very little precipitation fell, with Hurricane Francine providing most of it along the Gulf Coast. Overall, the central and eastern portions of the country saw continued deterioration, adding onto already expansive deterioration from last week. The Ohio River Basin continues to be the epicenter of the extremely dry conditions, though moderate and severe drought conditions are spreading through the southern Midwest into the Southeast. Improvements made along the Gulf Coast were primarily due to the well-above-normal precipitation brought by Hurricane Francine. There were some other areas of improvement in New Mexico, northeastern Arizona, eastern Utah, southern Wyoming and northwestern Montana. Areas of the West that have not seen any meaningful precipitation in a while are beginning to see dropping streamflows and drying soils…
The High Plains saw a mixed bag of improvements and degradations. The area remained hot and dry, except for eastern Nebraska and Kansas. Higher elevations of Colorado and Wyoming did receive some precipitation, but conditions remained mostly status quo. Kansas has experienced feast or famine precipitation since the beginning of summer. Some isolated, slow-moving thunderstorms provided good moisture in the center of the state, but abnormally dry or moderate drought conditions expanded along the Kansas western, southern and eastern borders. Eastern Colorado is beginning to show signs of a prolonged dry period, with moderate drought creeping further eastward from the Kansas border. Similarly, central and northern Wyoming are showing drier signals in the short-term, including soil moistures. These same conditions brought abnormally dry conditions along the North and South Dakota border and into southern and eastern Nebraska…
Colorado Drought Monitor one week change map ending September 10, 2024.
The West remained mostly dry with little to no precipitation and above-normal temperatures, except for southern New Mexico where conditions improve mainly on the residual effects of a wet few weeks and aided by below-normal temperatures. Central and northeastern Arizona into southeastern Utah also saw some improvements. Arizona also saw the expansion of moderate drought, overflowing into southern California. Central California also saw abnormally dry conditions expand. Northern Nevada, eastern Oregon and west-central Idaho saw widespread moderate drought expansion due to warm temperatures, lack of precipitation and drying soils. Washington into northwestern Idaho saw severe conditions expand, but extreme dryness was removed in Grant County, Washington as conditions were similar to the surrounding severe drought conditions.
The western portion of the South saw widespread improvements from central Texas to central Mississippi. Heavy rainfall from Hurricane Franciene dropped 2 to 6 inches of rain and the southeastern tip of Louisiana got as much as 14 inches of rain. Outside of the Gulf Coast, precipitation was lacking with precipitation hovering below normal. Temperatures were 2 to 6 degrees below normal, with localized areas being 6 to 8 degrees below normal. Central and southern Texas continued to see one-category improvements. Louisiana saw most of the abnormal dryness added last week removed due to abundant precipitation. Things started to degrade in Oklahoma, northeast Texas, Arkansas and northern Mississippi, where one-category degradations were widespread…
Looking Ahead
Over the next five days (September 11-16), precipitation is expected in the high elevation of Alberta Canada into Montana and Idaho, southern Arizona, and across the Gulf and southern Atlantic Coasts. Precipitation amounts of 2 to 5 inches are expected in Mississippi, northern Alabama, western Tennessee, the Florida Panhandle, and coasts of North and South Carolina.
The National Weather Service Climate Predication Centerโs 6-10 day outlook heavily favors above-normal temperatures from the north-central to eastern Canadian border to Texas-Mexican border with Minnesota, Wisconsin, and Michigan 80 to 95% likely to see above normal temperatures. Conversely, southern California and Arizona are 70 to 90% likely to see below-normal temperatures. Shifting northward towards the western Canadian border, there is a change of at- or slightly below-normal temperatures. Hawaii and northern Alaska are leaning toward above-normal temperatures.
The National Weather Service Climate Predication Centerโs 6-10 day outlook heavily favors above-normal precipitation in Montana and central Idaho, as well as the Atlantic Coast of Maryland, Virginia and North Carolina. Alaska and Hawaii are also leaning toward above-normal precipitation. Arizona, New Mexico, the Gulf Coast of Texas and Louisiana, and the Great Lakes region are leaning towards below-normal precipitation.

Denver Waterโs mission is water, but efforts to cut energy use and carbon emissions have become more front and center over the last decade.
After all, climate change threatens water supplies, so water utilities need to do their part to reduce the fossil-fuel ingredients that are warming the atmosphere and jeopardizing snowfall and river flows.ย [ed. emphasis mine]
Already, Denver Water powers its main Administration Building with solar panels, harnesses the power of water to generate enough hydroelectricity to juice 6,000 homes and employs a system that uses water, not air, to heat and cool its headquarters, making it easier and cheaper to keep temperatures comfortable.
But itโs not stopping there.
Always on the lookout for new sustainability features, Denver Water last year set a goal to cut its energy use by one gigawatt-hour. Thatโs 1 million kilowatt-hours โ a ton of electricity (or, in some cases, the equivalent amount of fuel, like gasoline) โ enough to power 750,000 homes for one hour, or roughly 100 homes for a year.
And, in the last 12 months, the utility accomplished its goal.
Employees scoured the organization for low-hanging fruit, the relatively easy fixes that could be done at little or no cost or would provide a rapid payback by quickly cutting energy expenses.
It takes all kinds of passionate people to ensure a clean, safe water supply for 1.5 million people. Join the team at denverwater.org/Careers.
And it unleashed its in-house expertise, including personnel specializing in electrical, HVAC, plumbing, information technology, vehicle fleet, dams, reservoirs and the network of pipes that moves water through the city.
Teams pinpointed energy savings that could be snared by closing unused facilities that were still drawing power, replacing outdated boilers in the utilityโs Winter Park facilities, updating old lighting, reducing the idling of fleet trucks (which wastes gas and diesel) and adding its first batch of electric vehicles โ among other steps.
โThis was an energy treasure hunt,โ said Adam Hutchinson, an energy management specialist and part of Denver Waterโs Sustainability Team. โWeโve focused on energy efficiency for many years now, but we wanted to take another hard look across the organization for relatively quick and easy energy-saving opportunities.โ
Hunt they did, and Denver Water employees put their expertise to work to find savings large and small.

Some of the finds were big, like taking out a problem boiler used to heat a key Denver Water facility in Winter Park, home to workers and a fleet of heavy equipment that helps keep things running in the high country.
The new equipment installed in Winter Park was more energy efficient, with an efficiency rating of 96% (compared to the old boilerโs 80% efficiency), and the switchover saved some 300,000 kilowatt-hours of electricity per year.
โWe installed a more efficient boiler that uses flue gas that would otherwise be expelled. The new equipment keeps it in the boiler to provide more heat,โ said Jeffrey Gulley, who leads the trade shop for Denver Water. โWe wanted to have efficiency and reliability with the frigid temperatures up there.โ
The utilityโs transmission and distribution employees determined that a few small, scattered facilities in the metro area could be closed and their functions consolidated. That amounted to cutting another 100,000 kilowatt-hours via reductions in heating, cooling and lighting.
Smaller changes also added up.
At Marston Treatment Plant in southwest Denver, an air bubbler keeps the water intake from freezing in winter months. Typically, the bubbler stays on constantly from November through May. But the simple addition of a temperature sensor means the bubbler can shut down when winter weather hits a warm stretch.
And boom! That simple sensor produced another 9,000 kilowatt-hours of savings โ enough to pay for itself in 18 months.

All told, the gigawatt project fit cleanly into the second phase of Denver Waterโs Sustainability Plan, which includes a goal to reduce greenhouse gas emissions by 50% by 2025 from a 2015 baseline.
And it chips away at a broader strategy: To drive down energy usage as low as possible, then get what power you still need through renewable energy.
โAll of this aligns with Denver Waterโs overall push to aggressively do our part to address climate change,โ said Kate Taft, the utilityโs sustainability manager. โOn the water planning side, we must adapt to the ongoing changes, but we can work on our operations side to reduce our own footprint. That is why we continue to move forward with change.โ
And continue it does. After reaching the 1-gigawatt (that is, 1 million kilowatt-hours) goal, ongoing work has found more savings.
Denver Water is now at 1.2 million kilowatt-hours in energy savings since setting the goal a bit over a year ago.
And all of this isnโt good news only for the environment. By cutting energy costs, Denver Water can also keep expenses down.
โWeโre driven on our sustainability goals,โ Hutchinson said. โAlong with that, weโre keeping in mind our customers and our rates.โ

Hunter and Woody Creeks and Avalanche and Thompson creeks in the Crystal River Basin are now designated Outstanding Waters by the Water Quality Control Commission. The Colorado Water Quality Control Commission on Aug. 21 unanimously designated roughly 385 miles of waterways across 15 rivers and streams in the upper and lower Colorado, Eagle, Yampa, and Roaring Fork River basins as Outstanding Waters.ย The Outstanding Waters designations are authorized by the Colorado Water Quality Control Act and the Clean Water Act…
โAn Outstanding Waters designation is a protection that can be given to reaches of streams that offer water quality protection. It is the highest level of water quality protection that can be given by the state of Colorado,โ [Mathew] Anderson said. โWith the protection, future projects that may happen along these reaches have to ensure that the water quality will not be diminished.โ
[…]
This designation can protect creeks and rivers from future developments and pollution. He noted that all existing industries, ranches, homes, and utilities along these sections of designations will be grandfathered in…He said that obtaining this designation took a coalition between different watershed groups that ranged from the Yampa to Eagle rivers…or creeks, streams, and rivers to receive this designation, the water quality must already be of a high standard. Eleven respective criteria points must be met as it relates to water quality before this designation can be obtained.

Here’s the release from the St. Vrain and Left Hand Water Conservancy District (Sean Cronin):
September 9, 2024
LONGMONT, COLO โ This fall, the St. Vrain and Left Hand Water Conservancy District (“District”) and the Highland Ditch Company are collaborating on a unique pilot project to save fish in St. Vrain Creek. As ditch diversions are closed off for the fall, fish often become trapped in standing pools behind the headgates, which eventually dry up. The pilot project will rescue these fish and return them to the adjacent creek, protecting local fish populations and aligning with the communityโs values of environmental stewardship.
Healthy fisheries are essential not only for the ecological health of local streams but also for supporting the recreational fishing economyโwell worth the half daysโ work it will take to move the fish back into the creek.
โThe District and Highland are piloting this salvage effort, in the hopes that the results may be scaled up across the District, and potentially in other parts of Colorado,โ said the Districtโs Watershed Program Manager Jenny McCarty.
Highland Ditch Company, which has been diverting water for over a century, sees this initiative as an example of the symbiotic relationship that can exist between local agriculture and environmental health.
The channelโs water โis used to irrigate 35,000 agriculture acres in this valley. Those farms are part of the fabric of this communityโฆ residents eat food from [these] farms,โ said Wade Gonzales, Highlandโs Ditch and Reservoir Superintendent. “We are all connected, and this pilot project will show how we can work together toward common goals.โ
โOur constituents across the St. Vrain and Left Hand Valley have time and again supported approaches that balance water needs for thriving agriculture and a healthy environmentโ, said Sean Cronin, the Districtโs Executive Director. โWeโre honored to be a trusted partner to Highland in leading this effort.โ
Media are invited to the fish salvage effort in late September, 2024. Date to be determined. Please email jenny.mccarty@svlh.gov if you are interested in attending.

September 9, 2024
This story is part of ongoing coverage of the Colorado River, produced by KUNC and supported by the Walton Family Foundation. KUNC is solely responsible for its editorial coverage.
Federal water managers will repair a set of little-used pipes within Glen Canyon Dam after discovering damage earlier this year. The tubes, called river outlet works, have been a focus for Colorado River watchers in recent years. If Lake Powell falls much lower, they could be the only way to pass water from the nationโs second-largest reservoir to the 25 million people downstream of the dam.
The Bureau of Reclamation will use $8.9 million from the Bipartisan Infrastructure Law to apply a new lining to all four pipes, which were originally coated more than 60 years ago. Conservation groups, however, say Reclamation should turn its attention and finances to bigger, longer-term fixes for the dam.
โDuct tape and baling wire won’t work in the long run,โ said Kyle Roerink, executive director of the nonprofit Great Basin Water Network. โThese short-term efforts are myopic in the grand scheme of things.โ
The river outlet works were originally designed to release excess water when the reservoir nears full capacity. Now, Lake Powell is facing a different problem: critically low water levels.
After more than two decades of climate-change-fueled drought and steady demand, the reservoir is less than 40% full. It was only 22% full as recently as 2023.

Currently, water passes through hydroelectric generators inside Glen Canyon Dam before flowing into the Colorado River. Water experts fear that shrinking supplies and unsustainably heavy demand will keep sapping Lake Powell, bringing the top of the reservoir below the intakes for the generators.

Not only would such a drop jeopardize power generation for about 5 million people across seven states, but it would leave the river outlet works as the only means of passing water from Lake Powell to the other side of the dam.
The pipes are only capable of carrying a relatively small amount of water. If they become the only means of passing water through the dam, the Colorado Riverโs Upper Basin states โ Colorado, Wyoming, New Mexico, and Utah โ could fail to meet a longstanding legal obligation to share a certain amount of water with their downstream neighbors each year.
That could mean less water for cities like Las Vegas, Phoenix and Los Angeles, as well as massive farm districts that put vegetables in grocery stores across the country.
Recent boosts in Lake Powell water levels are mostly due to back-to-back snowy winters, which climate experts say are becoming increasingly rare.
Conservation groups are putting pressure on policymakers to rein in demand. Some environmental advocates are asking them to consider draining Lake Powell altogether and storing its water elsewhere.
โWe need to start planning for a river with less water,โ said Eric Balken, executive director of the nonprofit Glen Canyon Institute. โThat means drastically rethinking infrastructure that was built for a much bigger river. As climate change and overuse continue to put pressure on this river system, Glen Canyon Dam’s plumbing limitations will become more and more problematic.โ
The back of Glen Canyon Dam circa 1964, not long after the reservoir had begun filling up. Here the water level is above dead pool, meaning water can be released via the river outlets, but it is below minimum power pool, so water cannot yet enter the penstocks to generate electricity.

September 9, 2024
DENVER – Governor Polis and the Colorado Department of Natural Resources (DNR) announced the release of the 2024 Colorado Strategic Wildfire Action Programโs Workforce Development Grant. In this release, $4 million is available for conservation corps, including those associated with the Colorado Youth Corps Association (CYCA) and Department of Corrections State Wildland Inmate Fire Teams (DOC SWIFT), to conduct wildfire mitigation projects and gain skills in forest restoration and wildfire risk reduction. The grant also funds mitigation and forestry training to educate and support the future workforce across the state.
โHere in Colorado we are aggressively expanding fire prevention strategies that work, and that includes the Colorado Strategic Wildfire Action Program. This funding will support mitigation efforts around the state that better protect homes and communities, and will also get Coloradans the skills needed to work in forestry,โ said Governor Jared Polis.
Coloradoโs Strategic Wildfire Action Program (COSWAP) was created after the devastating 2020 fire season by Governor Polis and the Colorado legislature as a collaborative effort between the Department of Natural Resources, Colorado State Forest Service, and the Division of Fire Prevention and Control to increase community resilience to wildfire. COSWAP addresses the urgent need to reduce wildfire risk in Colorado through workforce development and landscape-scale fuels reduction projects. Since the launch in 2021, COSWAP has funded 73 workforce development projects, totaling $10.3 million, and is now a permanent state program housed within DNR.
โI am proud of the impact COSWAP has made on workforce development and wildfire risk reduction across the state in its three years of operation,” said Dan Gibbs, Executive Director of the Department of Natural Resources. โThis next $4 million will increase the number of communities that benefit from the hard work of conservation corps and SWIFT members, providing on the ground hand crews to help reduce the risk of wildfire on our communities and critical infrastructure.โ
This is the third round of COSWAP Workforce Development funding. The grant provides two types of awards: crew time and cash grants. Crew time is awarded to grantees partnering with a CYCA accredited conservation corps or a DOC SWIFT crew where COSWAP pays for the mitigation work directly in order to reduce administrative burden on the grantee. Grantees who wish to work with an independent conservation corps can request a cash grant to hire the corps themselves. Cash grants are also available to cover program expenses or to support wildfire mitigation workforce training, including but not limited to: S-212 wildland fire chainsaw, advanced tree felling, prescribed fire training, and training for prescription development and treatment implementation.
โThe COSWAP program has exceeded expectations in changing lives and protecting landscapes,โ said Scott Segerstrom, Executive Director, Colorado Youth Corps Association. โWe are developing the next diverse generation of wildland firefighters and professional natural resource managers while also ensuring the lives and property of Coloradans in the most fire-vulnerable areas are secure. This public-private partnership represents the best of government: channeling resources into effective, proven solutions that lift up all communities.โ
Grants are available on all land ownership types in Colorado, however projects are only eligible in the following locations:
For independent and CYCA accredited conservation corps, projects must be located within identified Strategic Focus Areas, which include: Boulder, Douglas, El Paso, Jefferson, Larimer, La Plata, and Teller counties, as well as the Rocky Mountain Restoration Initiative focal areas.ย
The DOC SWIFT crews operate out of the Four Mile Correctional Facility in Canon City and can support projects within a three hour drive.
Wildfire mitigation trainings are available statewide.ย
New this year, all projects or trainings awarded through the 2024 Workforce Development Grant must be completed in 2025.
“The collaboration between the Department of Correctionsโ State Wildland Inmate Fire Team (DOC SWIFT) and the Colorado Department of Natural Resources has significantly enhanced our stateโs capacity to manage and mitigate wildfires. This initiative has not only strengthened our wildfire response but has also paved the way for meaningful post-incarceration employment opportunities, directly linking the skills developed on the fire team to future work prospects for those involved,” said Mitch Karstens, Deputy Director of Finance and Administration, Colorado Correctional Industries.

From email from Reclamation (Susan Novak Behery):
Due to falling flows in the critical habitat reach, the Bureau of Reclamation has scheduled an increase in the release from Navajo Dam from 600 cubic feet per second (cfs) to 800 cfs for Tuesday, September 10th, at 4:00 AM.
Releases are made for the authorized purposes of the Navajo Unit, and to attempt to maintain a target base flow through the endangered fish critical habitat reach of the San Juan River (Farmington to Lake Powell). The San Juan River Basin Recovery Implementation Program recommends a target base flow of between 500 cfs and 1,000 cfs through the critical habitat area. The target base flow is calculated as the weekly average of gaged flows throughout the critical habitat area from Farmington to Lake Powell.
This scheduled release change is subject to changes in river flows and weather conditions. If you have any questions, please contact Susan Behery (sbehery@usbr.gov or 970-385-6560), or visit Reclamationโs Navajo Dam website at https://www.usbr.gov/uc/water/crsp/cs/nvd.html

๐ต Public Lands ๐ฒ
The Bureau of Land Management released the final environmental impact statement and management plan for Grand Staircase-Escalante National Monument last month and Iโve been making my way through it (itโs a voluminous document, to put it mildly). A few things have really struck me:
Crafting a management plan for a 1.8-million-acre landscape that includes deserts, canyons, forests, riparian areas, and much more is a monumental undertaking.ย There are so many factors to consider, such a diversity of ecosystems to steward, and many competing interests to account for. This one is impressive for its thoroughness and for all of the science and information it contains about the current state of the land.ย
As is almost always the case with these sorts of things,ย the preferred alternative is a compromise, offering a lower level of protection than the more purely preservation-oriented alternative. Nonetheless it strives for conservation and is leaps and bounds stronger than the existing Trump-era plan, which will remain in effect if the new plan is not implemented. I took aย look at the draft planย and the โpreferredโ alternative C a year ago, which was the second-most restrictive of the lot. After receiving a boatload of input, the BLM went with a new approach โ Alternative E โ which is a modified version of Alt. C, and is more restrictive in some cases, less in others.ย
The preferred alternative would:ย โEstablish a management approach in collaboration with Tribal Nations that ensures continued Tribal Nation stewardship of GSENM resources.โย
Theย planโs light-handed approach to livestock gravingย provides yet more evidence that national monument designations pose virtually no threat to ranching, public lands grazing, and the โway of lifeโ they foster. So next time a Utah politician or wannabe sagebrush rebel whines about how the BLM or the Biden administration or national monuments are destroying ranching, show them this plan โ and remind them theyโre still paying just $1.35 per month for a cow and its calf to roam around public land and chomp up about 1,000 pounds of the taxpayersโ forage.ย
Now for some of the key elements of the plan (with maps from the preferred Alternative E):
The monument has four management areas:ย Front Country, Passage, Outback, and Primitive.
The monument includes 559,600 acres of lands with wilderness characteristicsย (i.e. lack of roads or development, โuntrammeled,โ etc.), but that arenโt designated wilderness areas. Alternative E would manage 329,400 acres of those lands for the protection of those characteristics, making them de facto wilderness areas; 224,100 acres would be managed to โminimize impactsโ; and 6,100 acres would be managed for other compatible uses. Thatโs compared to the status quo, which allows for other uses on all of those lands.
Hundreds of miles of roads, from paved highways to dirt two-tracks, are webbed throughout the national monument.ย Most have been claimed by the county as RS-2477 routes (which, if upheld by courts, would give the county control over them), and most remain open to motorized travel. Currently about 1,500 acres of the monument are completely closed to OHV travel, and OHV use is limited to designated routes on 1.86 million acres. Under the new plan, 1.25 million acres would be closed to OHVs, with OHVs still allowed only on designated routes on about 620,000 acres.
Currently,ย about 2.1 million acres in the national monument planning area (which extends beyond the boundaries) are available to grazing, un-permitted allotments can be reinstated, and suspended Animal Unit Months, or AUMs, can be reactivated.ย The new plan would put just 128,300 acres off-limits to grazingย โ a deep compromise, given that Alternative D would have halted grazing on 1.2 million acres โ and will allow cattle, but not sheep and goats, to chomp their way across 1.7 million acres.ย
There areย currently 76 grazing allotments in the monument, 14 of which are partially or completely unavailable to grazing, and 10 of which are vacant and available but are not currently permitted. The existing plan allows those to be re-permitted; the new plan would not.
There are currently 105,452 animal unit monthsย (a cow-calf pair grazing for one month), or AUMs, available in the planning area (76,207 active and 29,245 suspended). The 2020 plan directed the agency to reinstate the suspended AUMs, but it has not done so yet.ย Of the 76,207 active AUMs, operators only used (or were billed for) about 42,377 AUMs on average between 1996-2020. That suggests itโs the livestock operators themselves, not the land managers or monument protections, that are limiting grazing. There likely will still be aย lot of bovines munching on native grassesย and trampling the fragile cryptobiotic soils for years to come.ย
The new plan would allocate 104,980 AUMs.ย But, when people voluntarily relinquish a grazing permit or lease, the number of allocated AUMs would automatically decrease by that same amount, which theoretically would phase out grazing over time.
The agency estimates the cattle willย emit a total of 4,584 metric tons of methaneย annually under the preferred plan.ย
And you know those folks screaming and yelling that national monuments will destroy local โheritageโ and livelihoods and all of that?ย Some are well-intentioned but misinformed. Others are intentionally spewing disinformation in order to advance an ideological, sometimes corporate-driven, agenda. The Center for Western Priorities calls the latter the National Monuments Disinformation Brigade, and they just issued aย reportย on these folks.ย Give it a read. Regularย Land Deskย readers will see some familiar names.
Speaking of land management plans and giving the livestock industry everything it wants, the BLMโs Rock Springs field office also recently released its final resource management plan for about 3.6 million acres of public land in the southern part of the state, including the Red Desert. The draft plan was unexpectedly strong on the conservation side of things, and I held it up as proof that the BLM was shedding its Bureau of Livestock and Mining label (okay, maybe not the livestock part).
A lot of Wyoming right-wingers werenโt so pleased with it, though, with one wing-nut claiming it would affect more people than โthe Civil War, Pearl Harbor, and 9/11 combined.โ Except there arenโt even that many people in all of Wyoming!
Anyway, rather than sticking to its guns, the BLM went back to the drawing board and did what federal agencies often do, compromised (and bent over backwards to please the noisy minority โ and industry). The new plan, in my opinion, overcorrects and leaves 99.95% of the area open to grazing; designates areas of critical environmental concern on some 700,000 fewer acres than the draft plan; opens far more land to coal and trona mining, oil and gas drilling, oil shale extraction, and new mining claims. The new proposed plan also opens up more land than the draft to wind, solar, and geothermal development.
I chopped up the BLMโs chart and pasted it back together to allow for a quick comparison between last yearโs draft proposal, and this yearโs final preferred alternative plan.

Welp, Phoenix went and did it again by setting all sorts of records for armageddon-like heat. For example, it is now on the 107th consecutive day on which maximum temperatures reached 100ยฐ F or higher; the previous record was 76 days in a row back in 1993. The mercury has reached 110ยฐ on 55 days, matching the record set โฆ last year. The average monthly temperature has exceeded the 1990-2020 normal during six of the last eight months, and this climatological summer (June-August) was the hottest on record. All of thatโs crazy, disturbing, and scary โ yet not all that surprising, given that weโre clearly in the grips of human-caused climate warming. What is surprising is that when some kind-hearted Phoenician put a cooler full of bottled water in his driveway to offer free relief to passersby, his homeowners association went after him for violating some obscure rule. HOAs, hmmmph!

Sad news from Silverton, too: A mama bear died after a sheriffโs deputy shot it with a beanbag โ that was supposed to be nonfatal โ in an attempt to shoo the bruin away from people (who were gathered around gawking at her and her two cubs). The Durango Heraldreports the San Juan County Sheriffโs department is looking into allegations that someone harassed one of the cubs.

And, finally, some kind of cool news: The Ute Mountain Ute Tribeโs farm in southwestern Colorado has finished integrating a hydropower system into its irrigation network that will harness excess water pressure from pivot-sprinkler pipes. Itโs not a huge system, but it demonstrates one way to generate clean energy with minimal impact. Now letโs hope there continues to be enough water running through those pipes.
Click the link to read the article on The Denver Post website (Elise Schmelzer and Joe Rubino). Here’s an excerpt:
September 8, 2024
…after decades of revitalization and efforts to stabilize flows, sections of the urban South Platte still smell of decay and waste, andย city officials discourage swimming. But cyclists also pedal along miles of paved trails on the riverfront. Kayakers and surfers play in the whitewater. Carp and trout lurk under bridges, while families of ducks paddle along the calmer waters. And strips of green parks border long stretches of the river where, in previous decades, factories spewed sludge and landfills leached pollutants. After a long era of neglect and abuse, city officials, nonprofit leaders and developers hope to build on that progress as they pose a question for the future: How can we turn the city toward the river โ the waterway that made Denverโs existence on the High Plains possible โ instead of putting it at our backs and ignoring it? More than a quarter of a billion federal dollars are flowing into ecosystem restoration and flood management along the South Platte. For the first time, the Denver City Council recently created a committee dedicated to issues on and development near the river…
Developers plan to invest hundreds of millions of dollars along the river in coming years, building as much as 15 million square feet of combined new residential and commercial space on the land whereย Elitch Gardens Theme and Water Parkย sits today. If completed, that square footage will be nearly five times larger than Denver International Airportโs terminal building. Should that and other ambitious projects reach their full potential, the Platte would serve as a focal point of brand new high-rise urban neighborhoods that expand the cityโs skyline in a new direction…Property owners ranging from the Denver Housing Authority to Stan Kroenke, the billionaire owner of the Colorado Avalanche and Denver Nuggets, to the city itself will all play roles in determining how new construction capitalizes on a restored South Platte. The impending turnover of underutilized and unappreciated land has generated buzz and a glut of glossy renderings. At the same time, itโs inducing heartburn in some corners of the city that have seen new investment like that drive gentrification in nearby low-income and minority neighborhoods.
Still, establishing the river as an asset rather than a barrier to urban growth is a sea change that veteran Denver city-builders like architect Chris Shears have hoped for decades would come. His firm,ย Shears Adkins Rockmore,ย has its hands in nearly every landscape-shifting project being contemplated near the South Platte today. The plans include transforming the vast parking lots around Empower Field and Ball Arena into new mixed-use neighborhoods.
The company I work for recently built a new ticket office at the base of Buttermilk Mountain in Aspen, Colorado. Environmentally, we killed it: argon-gas-filled windows, super-thick insulation and comprehensive air sealing, 100 percent electrification using heat pumps instead of gas boilers. All within budget.
Yet one of the first comments we received was from a famous energy guru: โNice building. But why do you have a heating system at all?โ Or more simply put: โWhy didnโt you build a perfect building, instead of just a really good one?โ
Solving climate change could depend on how we answer that question. My answer: Society needs the Prius of buildings, not the Tesla X.
The green building movement didnโt originate only from a desire to protect the environment. It often had elements of the bizarre ego gratification that trumped practicality.
Recall โEarthshipsโ that used old tires and aluminum cans in the walls. Geodesic domes were interesting looking but produced inordinate waste to build. They also leaked. Rudolf Steinerโs weirdly wonderful Goetheanum was an all-concrete structure designed to unite โwhat is spiritual in the human being to what is spiritual in the universe.โ
Early practitioners such as Steiner, Buckminster Fuller, and Bill McDonough, among others, were often building monuments, whose ultimate goal became the concept of โnet zero.โ Net zero was a building that released no carbon dioxide emissions at all.
Designers achieved that goal by constructing well-sealed, heavily insulated, properly oriented and controlled buildingsโbut then they did something wasteful. They added solar panels to make up for carbon dioxide emissions from heating with natural gas. The approach zeroed out emissions, but at extraordinary cost that came in the form of added labor, expense and lost opportunity.
While net zero wasnโt a good idea even when most buildings were heated with natural gas, the rapid decarbonization of utility gridsโ happening almost everywhereโand advances in electrification make the idea downright pointless.
Instead, all you need to build an eventual net zero building is to go all-electric. It wonโt be net zero today, but it will be net zero when the grid reaches 100% carbon-free power. So, all that really matters is that building codes require 100% electrification.
Yet many communities remain focused on that sexy goal of net zero, and therefore include requirements for solar panels, or โsolar readyโ wiring. Even apart from the issue of cost, many utilities donโt need rooftop solar because they increasingly have access to huge solar arrays, giving them more electricity than they need in peak times.
What utilities really need is energy storage and smart management.
That means home batteries and grid integration that allows utilities to โtalkโ to buildings and turn off appliances during peak times. The problem is that environmentalists havenโt evolved: Just like we canโt retire our tie-dyes, we think โgreenโ means rooftop solar panels.
My companyโs Buttermilk building passes the only test that matters: โIf everyone built this kind of structure, would it solve the built environmentโs portion of the climate problem?โ The answer for our building is โyes.โ
Still, aspirational monuments matter. We need the Lincoln Memorial, the Empire State Building. But if weโre going to solve climate change in buildings, which is about a third of the total problem, new structures will have to reconceive what we consider efficient and beautiful. And it doesnโt have to break the bank.
Electrification, for example, is getting cheaper every year. Years ago, I served on an environmental board for the town of Carbondale in western Colorado. The overwhelming interest there was ending dandelion spraying in the town park. But at one point, we worked on a building.
After a long conversation about the technical tricks and feats we could pull off, a Rudolf Steiner disciple named Farmer Jack Reed said: โWe should also plant bulbs in the fall so colorful flowers blossom in the spring.โ โWhy?โ I asked, stuck in my own technocratic hole. He said: โBecause flowers are beautiful and they make people happy.โ

So, too, are realistic solutions as we adapt to climate change.
The Pagosa Area Water and Sanitation District (PAWSD) Board of Directors discussed funding mechanisms for the districtโs regulatorily required upgrades to the Vista wastewater treatment plant at its Aug. 29 meeting. Following a discussion, the board directed staff to move forward with seeking funding through a revenue bond publicly issued by the district to finance upgrades to the Vista plant required by Colorado Department of Public Health and Environment (CD- PHE) Water Quality Control Com- mission Regulation 85, in addition to other collection system improve- ments mandated by the CDPHE. Regulation 85 requires that certain wastewater treatment plants in the state reduce the amount of nutrients, such as nitrogen or phosphorus, con- tained in the outflows of treated water from the plants.

Grand Valley water managers have a plan to nip a potential zebra mussel infestation in the bud, with one irrigation district beginning treatment of its water this fall.
Officials are hoping to secure federal funding to treat the water that irrigators and domestic water providers pull from the Colorado River with liquid ionic copper, which kills zebra mussels. Mesa County plans to ask for the money through the U.S. Bureau of Reclamationโs Bucket 2 Environmental Drought Mitigation program.
Microscopic zebra mussel larvae, known as veligers, were found this summer in the Government Highline Canal, a crucial piece of irrigation infrastructure for the Grand Valleyโs agricultural producers. If these aquatic invasive species become established, it could be disastrous for the regionโs farms, vineyards, orchards and Coloradoโs famous Palisade peaches. The fast-reproducing mussels, which are native to Eastern Europe, can clog water infrastructure and are incredibly hard to eradicate once established.
โOur concern is for our smaller partners,โ said Tina Bergonzini, general manager of Grand Valley Water Users Association. โMany of our commercial peach growers and vineyards use microdrip irrigation. It would take just absolutely nothing to pinch off those systems completely, and it would be catastrophic. โฆ It could absolutely cripple agriculture from Palisade clear to Mack depending on the extent of the infestation.โ
Mesa County plans to apply on behalf of the irrigation districts and water providers for more than $4 million in funding, which will come from the remaining $450 million of Inflation Reduction Act funding for projects in the Colorado Riverโs Upper Basin (Colorado, New Mexico, Utah and Wyoming). โB2Eโ funding, as itโs called, is intended for projects that provide environmental benefits or ecosystem restoration and must be awarded to public entities or tribes. Several irrigation districts and domestic water providers would take part in the copper treatments: GVWUA, Grand Valley Irrigation Company, Orchard Mesa Irrigation District, Palisade Irrigation District, Mesa County Irrigation District and Clifton Water.
โMesa County recognizes the serious threat posed by the recent discovery of zebra mussels in the Colorado River and the Government Highline Canal,โ Mesa County Commissioner Bobbie Daniel said in a written statement. โWe understand the urgency of the zebra mussel situation, and that is why Mesa County is leading the charge in applying for federal funding to tackle this issue.โ

Palisade Irrigation District is not waiting for federal funding. It plans this fall to begin treating with copper the roughly 8 miles of the Price Ditch and its many laterals that irrigate about 5,000 acres of orchards, vineyards, alfalfa, cornfields and lawns. PID gets its water from the Government Highline Canal.
PID Superintendent Dan Crabtree saw the issues with quagga mussels, a relative of zebra mussels that causes similar problems, in Lake Powell on his yearly trips to the reservoir and knew mussels could someday become a problem for the Upper Basin too.
โIt just seemed inevitable that we would get them up here somehow,โ Crabtree said. โThe Palisade Irrigation District actually started a line item in our budget for this very thing maybe four years ago, so weโve got a little money set aside. Our system, I believe, is very susceptible to mussels because we are all pipes.โ
Crabtree said PID plans to start the copper treatment in October, which will cost the district about $60,000.
Copper has been used by water providers in the Colorado Riverโs Lower Basin (Arizona, California and Nevada), including the Central Arizona Project, to kill invasive mussels that threaten infrastructure. Experts say the treatment doesnโt harm fish or crops.
We know our Great Lakes are an enviable resource, one that is becoming more attractive to covetous states in the western U.S. that have been facing long-term drought, a process called aridification by some experts. No one is surprised that the squabbling has become more intense as the water supply out West has dwindled. With so many stakeholders, it will not be easy to reach a consensus on the changes that will need to be made to how this precious resource is managed and who will pay for it.
A recent guest essay in The New York Times, โWill We Have to Pump the Great Lakes to California to Feed the Nation?โ imagines a future in which we have no choice but to pump fresh water from hydrologically rich areas such as ours in order to supply farmers in the West or face starvation. That essay is not necessarily advocating the creation of cross-country pipelines or canals across the U.S. like what is being proposed in India and China.
While I recognize that water policy is intrinsically linked with food security for our nation, the headline is more than just misleading. It also is perpetuating a dangerous fallacy. The idea that water from the Great Lakes will solve the thirst of the western United States is not just a misplaced notion; it is also an obstacle delaying the inevitable reckoning with the unsustainable status quo.
The proposal to take water from the Great Lakes also ignores the existence of the legally binding interstate compact that governs how the states bordering them manage it. Known as the Great Lakes-St. Lawrence River Basin Water Resources Compact, it places strict limits on how much water can be used as well as who can divert it. Additionally, Canada borders four of the five Great Lakes, which means that our neighbor to the north has a say in what happens to these bodies of water. Often overlooked in this discussion, there are also governments of Native American tribes on both sides of the border in the Great Lakes region. None of these partners that share control of the Great Lakes would be willing to let water be shipped out of the Great Lakes Basin.

From Aug. 27 to Sep. 3, above-normal temperatures dominated the eastern United States, with areas along the Ohio River seeing temperatures upwards of 6 degrees above normal. The West and High Plains were a patchwork of above-, near- and below-normal temperatures. Isolated areas of southern New Mexico experienced temperatures of 5 degrees below normal. Overall, precipitation for most of the United States was within 1 inch of above- or below-normal conditions. This combination of hot and dry conditions led to continued drying in the Ohio River Basin, where conditions are dire. From Lake Superior southward to Alabama, drought conditions expanded with top and mid soil moisture and streamflow struggling. Texas and the western Gulf Coast saw over 8 to 10 inches of rain in some areas, quickly improving recent drying trends. In the West, there were dry conditions in the south and improving conditions in the Northwest…
Parts of the eastern High Plains received precipitation. The areas of North Dakota and South Dakota in need of precipitation missed the 1 to 3 inches that fell in the central and eastern parts of the states. Abnormal dryness spread towards central Nebraska as the precipitation this week was very spotty. Southeast Nebraska into north-central and northeast Kansas saw both abnormally dry and moderate drought conditions expand despite precipitation this week, due to longer-term dryness. Southwestern Kansas has been seeing conditions continue to improve, leading to the trimming of abnormally dry, moderate and severe drought. The eastern foothills and plains of Colorado experienced little to no rain this week, leading to the expansion of moderate drought. Along the western Colorado border with Utah, abnormal dryness was removed with increased streamflows aiding conditions…

The West was a mixture of improvements in the northwest and Four Corners areas and degradations in in the desert areas of Nevada, Arizona, and California, plus isolated areas of the northern Rockies. South and central New Mexico received moisture, allowing some of the longer-term impacts to improve slightly. Utah saw some improvements on the eastern border with Colorado but did see abnormally dry conditions expand in Juab County and Millard County. In the Southwest, along with southern Nevada, western Arizona and southern California, abnormally dry and moderate drought conditions expanded. Moisture deficits continued in these areas, with not enough precipitation to aid in current dry conditions. Conditions from northwestern Washington southward along the Pacific Coast into northern California have seen improvements in short-term dryness, with streamflows and soil moistures improving. In central and northern Washington, there is still some lingering long-term drought but these, similarly to areas of short-term drought, are showing improvement…
Massive amounts of precipitation fell over Texas and along the Gulf Coast of Texas and Louisiana. Parts of central Texas saw 8 to 12 inches of rain. This moisture reversed much of the abnormally dry conditions introduced last week in central and southeastern Texas and western Louisiana. Northern Texas and Oklahoma missed out on meaningful precipitation, and with persistent dry conditions saw expansion of moderate and severe drought along the Texas-Oklahoma border. Precipitation deficits and drying soil moisture led to Tennessee seeing eastward expansion of abnormal dryness and moderate drought…
Looking Ahead
Over the next five days (September 4-9) the West and High Plains are likely to see little to trace amounts of precipitation, except for areas in the higher elevation of the southern Rocky Mountains. There is a better chance for precipitation in the Great Lakes region. There are three tropical waves in the Atlantic, with two having a 40 to 60% chance of developing into a tropical or sub-tropical cyclone within the next seven days. With these tropical waves the Gulf Coast states are likely to see 2 to 3 inches of rain.
The National Weather Service Climate Predication Centerโs 6-10 day outlook heavily favors above-normal temperatures from the north-central Canadian border to Arizona-Mexican border. Surrounding areas to the west and east are leaning towards above-normal temperatures. From western Texas into Maryland the temperatures are expected to be near normal, with slightly increasing probability of cooler temperatures southward. Central and southern Florida are likely to see warmer-than-normal temperatures, along with the northern part of Alaska. The 6-10 day precipitation outlook is similar to the temperature outlook, though slightly shifted to the east. Areas of the northern Midwest are likely to see below-normal precipitation, with probability decreasing into the Rocky Mountains and Appalachian Mountains. There is a stronger probability that the Pacific Northwest and eastern Gulf Coast will see above normal precipitation. Hawaii and Alaska are also leaning toward above-normal precipitation.

From email from Western Resource Advocates (John Berggren and Lorelei Cloud):
August 15, 2024
Whole-basin forum that includes Indigenous knowledge would be safe place for difficult conversations and develop solutions together
The foundation of the laws, treaties, acts and policies that govern the Colorado River is the Colorado River Compact of 1922. Over the past 100 hundred years, dozens of additional agreements and decisions have been layered on top, providing for the management framework we know today.
As we look to the future, and as individuals who represent Tribal and environmental interests in the Colorado River Basin, we believe it is time to return to โ and reimagine โ one of the primary stated purposes of the 1922 Compact: to provide for the equitable use of water.
For me, Lorelei, itโs personal. Rooted in the Southern Ute Indian Tribe and raised on the Reservation in southwestern Colorado, my life has been deeply intertwined with water.
We lived in one of the first adobe houses on the Reservation and did not have running water. We relied in part on groundwater, but the well often dried up. So, we hauled water once a week and my grandmother boiled ditch water for drinking water as needed.
Water was a scarce resource, and we often had to choose between using water for drinking, taking showers or flushing the toilet. This scarcity is still a reality for many Native Americans today across the country.
I grew up knowing that water is a living, sacred being. Our Ute (Nuuchiu) culture centers around water, and we offer prayers for and with it. Water is the heart of our ceremonies. We were taught early on to take and use only what is needed. Above all else, we must care for the spirit of the water.
When I was first elected to the Southern Ute Tribal Council in 2015, I was asked to participate in the Ten Tribes Partnership, or TTP, which is a coalition of the 10 Tribes along the Colorado River focused on securing and using tribal water. After one year, I was asked to chair TTP.
I drew on my personal and spiritual connection to water and started learning about the complex legal and technical issues related to managing water in the American West. I was stunned to learn that Tribes have historically delegated to have little to no role in managing Western water, and that tribal needs and interests are often marginalized.
In recent years, I have had the opportunity to work alongside many people from diverse walks of life to begin addressing these inequities: lack of inclusion in decision-making; lack of access to clean water; and lack of capacity to manage, develop and use water.ย I became a founding member of the Water and Tribes Initiative, or WTI, for the Colorado River Basin; was the first Native American appointed to the Colorado Water Conservation Board and the Colorado Chapter of The Nature Conservancy; co-founded the Indigenous Womenโs Leadership Network, a program of WTI; and helped forge an historic agreement among the six tribes in the Upper Basin the Colorado River and the states of Wyoming, Colorado, Utah, and New Mexico to allow Tribes to be more meaningfully involved in collaborative problem-solving (but not decision-making per se).
Like Tribes, environmental interests have mostly taken a backseat to the use of the Colorado River for municipal and agricultural purposes. Most adjustments to address cultural and ecological values have been treated as subservient to the allocative laws that largely service municipal and agricultural interests.
Returning to the primary purpose of the 1922 Compact, we believe that providing for the equitable use of water includes substantive and procedural elements. Thereโs a huge difference between how the Colorado River is managed for multiple values (substance) and how people who care about such issues determine what ought to happen (process).
We are offering a process improvement. We believe itโs time to establish an ongoing, whole-basin roundtable that would embrace the entire transboundary watershed, address the major water issues facing the basin, and, importantly, provide an equitable process to engage all four sets of sovereigns (United States, Mexico, seven basin states and 30 Tribal nations), water users and stakeholders.
The late University of Colorado law professor David Getches, an astute observer of Colorado River law, noted in 1997 that โthe awkwardness and the intractability of most of the Colorado Riverโs problems reflect the absence of a venue to deal comprehensively with Colorado River basin issues.โ He called for โthe establishment of a new entity that recognizes and integrates the interests and people who are most affected by the outcome of decisions on major Colorado River issues.โ
Many other scholars and professionals have supported a whole-basin approach to complement, not duplicate, other forums for engagement and problem-solving in the basin. Establishing a whole-basin forum is also consistent with international best practices, as most transboundary river basins throughout the world have some type of river basin commission.
A whole-basin forum would be a safe place to have difficult conversations, to exchange information, build trust and relationships, and to develop collaborative solutions. It should rely on the best available information, including Indigenous knowledge.
Addressing the historic inequities built into the fabric of governing the Colorado River requires innovative substantive tools as well as procedural reforms focused on engagement and problem-solving. We look forward to working with all of you to shape a more equitable, more sustainable future for the Colorado River.

A vicious cycle of climate change, wildfires and air pollution is having a spiralling negative impact on human health, ecosystems and agriculture, according to a new report from the World Meteorological Organization (WMO).ย
Key messages
WMO Air Quality and Climate Bulletin highlights interlinkages
Action against air pollution and climate change is win-win solution
Wildfire smoke harms human, ecosystem and crop health
Wildfire emissions cross borders and entire continents
Particulate matter levels show differing regional trends
The WMO Air Quality and Climate Bulletin includes a special focus on wildfires. It also looks at global and regional concentrations of particulate matter pollution and its harmful effects on crops in 2023.
The WMO bulletin was released for Clean Air for Blue Skies Day on 7 September. This yearโs theme is Invest in Clean Air Now. Ambient air pollution causes more than 4.5 million premature deaths annually and wreaks a high economic and environmental cost.
The bulletin, the fourth in an annual series, explores the intricate relationship between air quality and climate.
The chemical species that lead to a degradation in air quality are normally co-emitted with greenhouse gases. Thus, changes in one inevitably cause changes in the other.
Air quality in turn affects ecosystem health as air pollutants settle from the atmosphere to Earthโs surface. Deposition of nitrogen, sulfur and ozone reduces the services provided by natural ecosystems such as clean water, biodiversity, and carbon storage.
โClimate change and air quality cannot be treated separately. They go hand-in-hand and must be tackled together. It would be a win-win situation for the health of our planet, its people and our economies, to recognize the inter-relationship and act accordingly,โ said WMO Deputy-Secretary-General Ko Barrett.
โThis Air Quality and Climate Bulletin relates to 2023. The first eight months of 2024 have seen a continuation of those trends, with intense heat and persistent droughts fuelling the risk of wildfires and air pollution. Climate change means that we face this scenario with increasing frequency. Interdisciplinary science and research is key to finding solutions,โ said Ko Barrett.
Global 2023 particulate matter concentration
Particulate matter PM2.5 (i.e. with a diameter of 2.5 micrometers or smaller) is a severe health hazard, in particular if inhaled over long periods of time. Sources include emissions from fossil fuel combustion, wildfires and wind-blown desert dust.
The WMO bulletin used two independent and different products to estimate global particulate matter (PM) concentrations: the Copernicus Atmospheric Monitoring Service and the National Aeronautics and Space Administrationโs Global Modeling and Assimilation Office (GMAO).
Both products found that wildfires over North America caused exceptionally high PM2.5 emissions compared to the reference period 2003โ2023.
Above average PM2.5 levels were also measured over India, due to an increase in pollution emissions from human and industrial activities.
By contrast, China and Europe measured below-average levels, thanks to decreased anthropogenic emissions. This continues a trend observed since the WMO Bulletin was first published in 2021.

Particulate matter has a major impact not just on health, but also on agriculture. It can reduce crop productivity in areas where maximizing yield is of crucial importance for feeding the population.
Global hotspots include agricultural areas in Central Africa, China, India, Pakistan and South-East Asia.
Experimental evidence from China and India indicates that particulate matter can reduce crop yields by up to 15% in highly polluted areas. It reduces the amount of sunlight reaching leaf surfaces and physically blocks leaf stomata which regulate exchange of water vapour and carbon dioxide with the atmosphere.
Agriculture itself is a major contributor to PM through release of particles and their precursors by stubble burning, fertilizer and pesticide applications, tillage, harvesting, and manure storage and use.
The WMO bulletin provides practical solutions, including planting trees or shrubs to physically shelter crops from local sources of PM, with added carbon sequestration and biodiversity benefits.
Wildfires
There were hyper-active wildfire seasons in both the northern and southern hemisphere in 2023.
There are many different causes of wildfires, including land management and human actions (both accidental and arson). But climate change also has an indirect role by increasing the frequency and intensity of heatwaves and prolonging drought. These conditions heighten the risk and likelihood of forest fires spreading, which in turn has a major impact on air quality.
โSmoke from wildfires contains a noxious mix of chemicals that affects not only air quality and health, but also damages plants, ecosystems and crops โ and leads to more carbon emissions and so more greenhouse gases in the atmosphere,โ says Dr Lorenzo Labrador, a WMO scientific officer in the Global Atmosphere Watch network which compiled the Bulletin.
The 2023 wildfire season set a multi-decade record in Canada in terms of total area burned, with seven times more hectares burned than the 1990โ2013 average, according to the Canadian National Fire Database.
Many large and persistent fires burned from the first week of May in western Canada (where it was unusually warm and dry) until the end of September. This led to worsening air quality in eastern Canada and the north-eastern United States, particularly in New York City (in early June). Smoke was transported across the North Atlantic Ocean as far as southern Greenland and Western Europe.
This resulted in cumulative total particulate matter and carbon emissions well above the annual average of at least the past 20 years.

Central and southern Chile was struck by devastating wildfires in January and February 2023, with at least 23 deaths. More than 400 fires, many of them intentional, burned vast regions of plantations and woods. High temperatures and winds fuelled the fires in an area affected by a pervasive drought that has lasted more than a decade. The National Air Quality Information System recorded increased levels of all air pollutants in all stations.
As a result, the daily short-term exposure to ozone increased drastically at several monitoring stations. Chilean authorities declared a state of environmental emergency in various regions of central Chile.
โConcurrent observations of ozone, carbon monoxide, nitrogen oxides and PM2.5 in central Chile exhibit the extreme detriment to air quality caused by intense and persistent wildfire events made more common in a warming climate,โ write the Bulletin authors.
The Air Quality and Climate Bulletin also looks at:
Aerobiology. Accurate and timely information on concentrations of what is known as “primary biological aerosols” (i.e. plant pollen, fungal spores, bacteria, etc), is in high demand from medical practitioners and allergy sufferers, agriculture and forestry industries, and climate change, biodiversity and air quality researchers, to name a few.
Bioaerosols play an important role in climate studies: vegetation is one of the most sensitive indicators of climate change. Biodiversity changes and plant flowering time, intensity and distribution patterns are all sensitive to meteorological conditions.
Over the past few years, and due to technological advances, new technologies have made it possible to obtain information on bioaerosol concentrations in real time. These new techniques open entirely new possibilities for the wide range of stakeholders interested in bioaerosols.
