Here’s the release from Northern Water (Jeff Stahla):

Northern Water’s Municipal Subdistrict celebrated the groundbreaking for Chimney Hollow Reservoir on Friday, culminating a 20-year permitting process to add resilience to the water supply for more than 500,000 northeastern Colorado residents.

The groundbreaking also triggers a host of environmental efforts that will occur in the headwaters of the Colorado River on the West Slope. Those include construction of the Colorado River Connectivity Channel to reconnect portions of the river located above and below Windy Gap Reservoir, wastewater treatment plant upgrades in the Fraser River Valley, environmental improvement projects through the Learning By Doing coalition, and other work providing water and storage that can be used for environmental purposes.

“Today marks a long-awaited milestone that required years of hard work and cooperation among many groups with diverse interests to achieve a project that has benefits for everyone in Colorado,” said Northern Water General Manager Brad Wind.

The addition of water storage is a key component of the Colorado Water Plan. Our population continues to grow as climate change brings higher temperatures and greater precipitation variability to the Colorado River headwaters. Construction of Chimney Hollow Reservoir gives the regional Windy Gap Firming Project participants a reliable water supply during dry years.

Since the Windy Gap Project was envisioned, water managers have recognized the need for additional storage specifically dedicated to storing Windy Gap water. Currently the Windy Gap Project depends on Lake Granby to store water when the project’s water rights are in priority. However, Lake Granby’s first priority is to store Colorado-Big Thompson Project water.

Chimney Hollow Reservoir is a key component for these Windy Gap Firming participants: Broomfield, Platte River Power Authority, Loveland, Greeley, Longmont, Erie, Little Thompson Water District, Superior, Louisville, Fort Lupton, Lafayette and Central Weld County Water District. Each of the reservoir project participants that provide residential water service has committed to reduce per capita water supply through water conservation.

Northern Water’s Municipal Subdistrict and Larimer County cooperated to purchase the Chimney Hollow property in 2004 from Hewlett-Packard. Chimney Hollow Reservoir will provide a much-needed outdoor recreational opportunity that can be enjoyed by everyone in Northern Colorado.

In recent weeks crews have been preparing the site for construction by bringing water and power to temporary administrative offices. In addition, the Western Area Power Administration relocated a high voltage power line from the footprint of the reservoir to a location up the hillside to the west.

Full dam construction activities are planned to begin Aug. 16. Barnard Construction Co. Inc. of Bozeman, Montana, is the general contractor for the four-year project. The cost of dam construction is estimated at $500 million, with the complete project including West Slope improvements at $650 million. The 12 project participants are paying its cost.

This graphic, provided by Northern Water, depicts Chimney Hollow Reservoir, located southwest of Loveland, after it is built.

When the dam is built, it will rise about 350 feet off the dry valley floor. The dam incorporates a technology common in Europe but less so in the United States. Its water-sealing core will consist of a ribbon of hydraulic asphalt instead of the clay that serves that purpose at the Carter Lake and Horsetooth Reservoir dams. Geologists discovered there wasn’t enough high-quality clay material within the footprint of Chimney Hollow Reservoir, and instead of bringing it in from elsewhere, the hydraulic asphalt core option was chosen. The dam’s rock-fill shoulders will use material mined from the reservoir footprint, which will reduce costs, pollution and increase storage capacity.

This new storage project allows us to supply clean water reliably, even in times of drought, to the people of northeastern Colorado from the existing Windy Gap Diversion. Starting construction on Chimney Hollow Reservoir is a major step to address water supply shortages for our growing population, much like our visionary predecessors did for us, while demonstrating that modern storage projects can also improve the environment.

More than 500,000 Coloradans across the Front Range can look forward to a more resilient water supply in the near future, after a groundbreaking Friday set in motion a $650 million project that will give water providers more reliable access to a vital resource that’s become increasingly scarce due to growing populations and climate change.

A crowd of about 200 gathered Friday morning for the groundbreaking of the Chimney Hollow Reservoir, a 90,000 acre-foot reservoir at least 20 years in the making. The reservoir will be located west of the Flatiron Reservoir in Larimer County.

A dozen municipalities, water providers and a power authority are participating in the Northern Water project, which boasts a price tag of $650 million, $500 million of which is for the dam construction. Other costs are going to environmental and water quality improvements in collaboration with affected communities. Adding in things like permitting costs, project manager Joe Donnelly said the total program costs were about $690 million.

Greeley is one of the participants, making up about 10% of the project. Other participants include Longmont, Fort Lupton, Central Weld County Water District, Broomfield and more. Greeley Water and Sewer director Sean Chambers said the city is putting about $57 million toward the construction…

The project had relied on Lake Granby to store water when the project’s water rights were in priority, but the lake’s first priority is to store Colorado-Big Thompson water. Over time, it became clear Front Range water providers would need a way to store Windy Gap water because the water wasn’t available when Front Range communities needed it the most…

Northern Water cooperated with Larimer County to purchase the Chimney Hollow property from Hewlett-Packard in 2004…

Drager and other speakers detailed numerous setbacks, including years of federal litigation after environmental groups filed a 2017 lawsuit. A judge in December dismissed the lawsuit, according to BizWest. The biggest setback, according to Drager, was needing to get a 1041 permit from Grand County. State officials also took issue when project officials hadn’t developed a mitigation plan with the state.

“We kind of argued a little bit, but we came to the conclusion that to really make this thing work, we would have to give something,” Drager said.

In a meeting with a Division of Wildlife official, they eventually settled on stream restoration for the Colorado River — one of many environmental considerations and concessions that helped pave the way for the partnerships that made the project possible…

Though some environmental work is being done at the site, most is at the headwaters of the Colorado River, according to Northern Water spokesman Jeff Stahla. The environmental mitigation and improvements will cost more than $90 million, including about $45 million to provide water for the river when it’s running low. Other improvements include helping the town of Fraser upgrade its wastewater treatment plant and stream restoration projects.

“These are things that wouldn’t have happened if this project doesn’t get built,” Stahla said. “By doing these things, it’s … mitigation and enhancement, because we’re not just mitigating for the effects of this project, but we’re enhancing what’s already there.”

The site will also serve as an outdoor recreational opportunity managed by Larimer County.

From Big Pivots (Allen Best):

Settlement involving Windy Gap yields $15 million for science-based work

In the early 1980s, when a dam on the Colorado River near its headwaters was proposed and Andrew Miller was a writer for the Winter Park Manifest, he wrote an editorial called “Requiem for a Cottonwood Grove.”

The headline was premature because the dam at Windy Gap, where the Fraser River flows into the Colorado, had not yet been constructed. But it soon was, causing the cottonwood trees to be felled and allowing water from the new reservoir to be pumped uphill to Grand Lake. From there the water flows into diversion under the Continental Divide called the Alva Adams Tunnel to be distributed among cities and some farms in the northern Front Range.

But that story almost 40 years later continues, as news of a settlement suggests. The Grand Foundation will soon receive $15 million remediation for work in Grand County, where the Colorado River originates. The money will be used to try to create strategies for preserving trout and other aquatic life in the warming but ever-more shallow waters.

The big story here is of incremental depletions of the Colorado River at its headwaters by growing Front Range cities now colliding with the impact of the warming climate, hotter and drier. The two, each powerful, leave in doubt how long cold water-loving trout can survive.
“Trout need water temperatures below 70 degrees, and we are regularly bumping up against 70 degrees in our rivers,” says Miller, now a contractor and president of the Upper Colorado River Watershed Group.

The $15 million will come from the municipal subdistrict of the Northern Colorado Water Conservancy District responsible for this incremental diversion. The district built Windy Gap to divert the waters to the northern Front Range. A subsequent project spurred by the distressing drought of 2002 and those of later years yielded an expansion of the diversions at Windy Gap.

This graphic, provided by Northern Water, depicts Chimney Hollow Reservoir, located southwest of Loveland, after it is built.

The additional water will be stored, in part, at a new reservoir snuggled among the foothills rising from the Great Plain southwest of Loveland. The dam to create that 90,000-acre-foot reservoir, called Chimney Hollow, has not yet been constructed.

The political subdivision responsible for the new diversion consists primarily of towns and cities, from Broomfield, Superior and Fort Lupton on the south to Loveland and Greeley on the north.

Save the Colorado and the Sierra Club, among other groups, in 2017 had sued Northern, arguing that the process used to review the impacts was deficient in failing to adequate address cumulative impacts. In December 2020 a federal court ruled in favor of Northern, but the environmental groups appealed.

In April, a compromise was announced. The environmental groups dropped the lawsuit and Northern agreed to the $15 million settlement in what Northern described as a productive alternative to costly litigation.

The financial documents of the settlement agreement are to be signed by directors of Northern on Aug. 6 and by the Grand Foundation on Aug. 10. Because of delays in signing, Northern will transfer the first payment totaling $5 million immediately after the Grand Foundation signs, says Gary Wockner, of Save the Colorado and an allied group, Save the Poudre.

Administering the $15 million grant will be the Grand Foundation, which is to consist of three members from Miller’s organization, the Upper Colorado River Watershed Group. In addition to Miller, Dave Troutman the treasurer, and Geoff Elliott, the staff scientist, will be on the committee responsible for overseeing allocation of the grant. Northern Water has authority to name the three other members.

“Our charge over the next 10 years is to spend $15 million in ways that improve Grand County’s watershed in a collaborative process,” explained Miller. “In some ways, we are on opposite sides of the fence,” he said, referring to the Northern District’s appointment members. “But in many of the important ways we are on the same side. We both depend upon high-quality water, Northern almost more than us.”

Other measures in the agreement address water quality and provide more water for Western Slope users.

Restoring a river channel in the Upper Colorado Basin

Separately, Northern plans to create a new channel around Windy Gap Dam, to allow the Colorado River to flow without impoundment. The channel is intended to allow fish, macroinvertebrates, nutrients and sediment in the river to bypass the dam and reservoir. The project is called the Colorado River Connectivity Channel. The bypass channel will be the result of a settlement negotiated by Trout Unlimited and others, says Wockner. No draft environmental assessment has been released. “It remains to be seen if the channel will be permitted, funded or built,” he says.

Because of its proximity to the northern Front Range farms and cities and its relative plentitude of water-producing snow, Grand County has been the go-to place for trans-mountain diversions since the late 1880s. The two most significant are those accomplished by the 6.2-mile pioneer bore of the Moffat Tunnel, which allowed diversions from the Winter Park and Fraser area to begin in 1936; and the 13.1-mile Adams Tunnel, which began delivering water to the Estes Park area in 1947.

Miller sees pressing task of the foundation set up to administer the settlement funds will be to lay down a baseline of existing conditions. The existing data, says Miller “really aren’t that good.”

Beyond that, the challenge will be more difficult, perhaps impossible.

“Basically we need to figure out how to run a watershed when we only have 30% of the natural water, which is about all we have left after the diversions by the Front Range.”

In addition to the stepped-up diversions by Northern Water, Denver Water also wants to take additional water through the Moffat Tunnel for impoundment in an expanded Gross Reservoir.

By at least some estimates, 70% of the native water of eastern Grand County currently gets exported to the Front Range. With these new diversions, exports will increase to 80%.

When these incremental diversions were first conceived not quite 20 years ago, the science of global warming was firming up but the effects were not yet evident, at least not like now. Even a decade ago, after significant drought had begun and temperatures had clearly started rising, the big picture was more tentative.

Miller’s group contends no water remains available from the Grand County headwaters of the Colorado River for additional diversion.

“I don’t think anybody realized how persistent this drought would be,” says Miller. “It could be a forever thing. We have created a new climate, and we will never see the rainfalls and snow we have in the past.”

From The Summit Daily (Taylor Sienkiewicz):

Downstream call placed on the reservoir for irrigation water rights

Green Mountain Reservoir, one of the biggest reservoirs in Summit County, located in Summit County, is low this summer, but it’s not as low as in previous drought years.

The reservoir is currently storing about 101,000 acre-feet of water — 32.9 billion gallons — James Heath, division engineer for the Colorado Division of Water Resources, said in an email. He noted that the reservoir is typically nearly full around this time of year. A full Green Mountain Reservoir is about 154,000 acre-feet of water, or approximately 50 billion gallons.

However, Heath said in previous drought years like 2002 and 2012, there was less water stored in the reservoir than there is this year.

Heath explained that the runoff from the Blue River this year was not enough to fill both Dillon Reservoir, which is upstream, and Green Mountain Reservoir, which is downstream…

Releases from Green Mountain Reservoir make their way to the Colorado River to appease those downstream with senior water rights. Heath said these releases replace upstream depletions from West Slope diversions and the Colorado Big Thompson project, which delivers the approximate volume of Dillon Reservoir to the South Platte Basin.

Heath noted that there has been a call for irrigation water rights downstream in the Grand Valley, which means senior water users have requested to restrict the use of water among junior water users because there is not enough water in the system to allow all water diversions. This requires Green Mountain Reservoir to stop storing, pass inflows and make releases.

While calls on Green Mountain Reservoir can restrict use for junior water users, there is a group of western Colorado water users that have historically benefited from releases out of Green Mountain Reservoir, called historic user pool beneficiaries, that are allowed to continue to divert after a call is placed on the river.

Since July 10, the reservoir water level has dropped about 7,000 acre-feet, or 2.2 billion gallons, according to the Colorado Division of Water Resources website. For most of July, Green Mountain Reservoir’s discharge to the Blue River was below the historic average.

With critical #water supply project facing unacceptable risk, #Denver Water seeks relief from Boulder County process in federal court

Denver Water is planning to expand Gross Reservoir in Boulder County. The additional storage capacity will create more balance in the utility’s storage and give water planners more flexibility in their operational strategy. Photo credit: Denver Water.

Here’s the release from Denver Water:

Denver Water today [July 14, 2021] filed a lawsuit in U.S. District Court against Boulder County, asserting the county is overreaching its authority and jeopardizing a federally ordered reservoir expansion critical to a safe and secure water supply for one quarter of the state’s population while risking long-planned benefits for the West Slope environment.

BACKGROUND

For nearly two decades, Denver Water has conducted an exhaustive and comprehensive planning and permitting process at the direction and oversight of six federal and state regulatory agencies. That process culminated last year in a final order to commence expansion of Gross Reservoir from the Federal Energy Regulatory Commission, which has final authority over the expansion project because Gross Reservoir occupies federal lands specifically designated for hydropower production.

For years, Denver Water has also attempted good faith efforts to work with Boulder County to secure county permits, including through two attempts at an intergovernmental agreement, robust engagement with county staff and neighbors, and participation in a local land-use review known as the “1041 process.” Unfortunately, Boulder County has been unreceptive and is using the 1041 process to frustrate the project, extending and delaying its review to the point that it is now placing the entire project at risk.

DENVER WATER STATEMENT ON NEED FOR THE PROJECT

It is hard to overstate the importance of the expansion of Gross Reservoir to the future of the Denver region. It will offer crucial protection to the utility’s water supplies from the urgent threat of catastrophic wildfire and prolonged drought — the same forces that nearly 20 years ago combined to threaten Denver Water’s ability to ensure drinking water to its customers.

This risk to clean water supplies is even higher today, in an era of rapid climate change and increasing periods of extreme weather. Last year’s record wildfire fire season, which generated the three largest forest fires in Colorado history, only just missed triggering major impacts to Denver Water’s supplies. Water providers to the north haven’t been as lucky, unable to treat some supplies running black and brown with ash produced by the Cameron Peak fire. Denver Water must act now to mitigate these risks.

The Gross Reservoir expansion conforms in every way to benchmarks in Colorado’s Water Plan, a plan developed through statewide and bottom-up guidance from eight major river basins over two years and published in 2015. That plan calls for increasing the capacity of existing reservoirs as a key element in creating 400,000 acre-feet of additional storage in the state by 2050.

The State of Colorado, in comments to the U.S. Army Corps of Engineers, expressed its support for the Gross Reservoir expansion and has identified it specifically as fitting within the kind of project defined as necessary in Colorado’s Water Plan: “A significant portion of Colorado’s future needs will be met with the implementation of projects and planning processes that the local water providers are currently pursuing, including the Moffat Collection System Project” (aka Gross Reservoir expansion).

The reservoir expansion also addresses the significant need for additional supplies in the metro region, as referenced in the Water Plan’s 2019 technical update. That update projected metro Denver demand will increase by 134,000 acre-feet to 280,000 acre-feet by 2050 against a 2015 baseline and the area likely will experience a supply shortfall, even accounting for the Gross Reservoir expansion and other water projects, a drop in per-capita use, and further conservation and reuse.

DENVER WATER STATEMENT ON DEVELOPMENT OF THE PROJECT

Denver Water’s diligent and earnest work to build partnerships across the Continental Divide, conduct significant and ongoing environmental mitigation for the project and work closely with regulators since the early 2000s has earned the project the support of major environmental groups, Grand County and each of the last five governors of Colorado. The Colorado Department of Public Health and Environment concluded the project would result in net water quality improvement on both sides of the Continental Divide.

The dam, when built in the 1950s, was designed to be raised. In the 1980s, amid discussion of the Two Forks project southwest of Denver (later vetoed by the EPA) a coalition of environmental groups recommended the expansion of Gross Reservoir as a viable, environmentally stable project. “We feel that additional capacity at Gross Reservoir is an environmentally acceptable and cost-effective way of increasing the overall yield of the system,” the coalition wrote. It included representatives of the Sierra Club, the Environmental Defense Fund and Trout Unlimited, among several other groups.

Denver Water also worked industriously with local governments and citizen groups on the West Slope to address the impacts that putting more water in an expanded Gross Reservoir would have on streams in Grand County. Those talks, often intense, and spanning half a decade, resulted in the Colorado River Cooperative Agreement in 2013, an unprecedented cooperative effort involving 18 signatories and 40 partner organizations that began a new era of collaboration and conflict-resolution between Denver Water and the West Slope.

Expanding Gross Reservoir locks in a key component to that agreement: Denver Water would place a geographic limit on its service area, putting to rest fears the utility would continue to expand its reach to an ever-sprawling suburban ring. The utility also agreed to several measures that would provide more water to West Slope rivers, towns and ski areas and invest in improvements to aquatic habitat. The landmark concord also affirmed that with the Gross Reservoir expansion, Denver Water would benefit from more flexibility in its system, and it would use that flexibility to address stream flow and stream temperature concerns more nimbly and readily in Grand County.

Additionally, Denver Water worked with the cities of Boulder and Lafayette to establish an environmental pool in Gross Reservoir to provide additional water in South Boulder Creek during low-flow periods. Water in that pool would also supplement supplies for those two cities. Many of these commitments, however, depend on the project going forward and are therefore in jeopardy through Boulder County’s actions.

As planning for the expansion moved ahead, the utility undertook a proactive strategy to reduce demand. It deployed a water recycling facility to reduce its dependence on West Slope water supplies, embarked on a conservation program renown nationally for its success — cutting per capita water use by 22% between 2007 and 2016 — and has now undertaken direct efforts at water efficiency that pinpoint savings opportunities at the individual customer level. These are only a sample: The utility remains committed to innovation to drive further savings and expand water reuse as a core part of its strategy, work that will continue to be essential even with an increase in storage at Gross Reservoir.

In short, the effort to build civic and regulatory support for the Gross Reservoir expansion has been persistent, inspired and earnest. The future of the region, its access to clean, safe drinking water, protection of its urban tree canopy and environment, and its economic development rest in large part on the ability of Denver Water to protect water supplies from emerging threats, develop a climate-resilient system and remain prepared for the demands that will result from continued growth within its service area in metro Denver.

DENVER WATER STATEMENT ON BOULDER COUNTY’S PROCESS

Boulder County is endangering the project through delays, repeated and expanding requests for information — information demands that duplicate the already completed federal permitting process in which Boulder County participated — the potential for months of additional hearings and the fact that two of the county’s three commissioners have already publicly stated their opposition to, and desire to stop, the expansion project.

Further, the county’s land use director informed Denver Water on June 29 that the utility — despite over nine months of diligent and painstaking work to respond to Boulder County’s ever-expanding queries — failed to provide sufficient information to county agencies about the project, setting the project up for failure and rendering further involvement with the 1041 process futile.

These actions also put engineering and construction deadlines at risk, threaten to disrupt FERC-ordered timelines and risk other permits and actions necessary for successful completion of the project. A project of this size and complexity requires extensive preplanning, substantial resources and a highly skilled design and construction team. Delays resulting from Boulder County’s refusal to timely process the 1041 application add substantial costs and cause permitting, procurement and logistical issues that seriously disrupt Denver Water’s ability to execute the project.

In summary, the actions of a single local jurisdiction, Boulder County, threaten to derail and undermine a federally permitted and state supported project vital to a safe and secure water supply for one-quarter of Colorado’s population. This presents an unacceptable risk to a critical project spanning nearly 20 years and involving intensive review by environmental agencies at the federal and state levels and the engagement of dozens of organizations and communities across the metro area and the West Slope.

For that reason, Denver Water must seek relief in federal court. The complaint further details Denver Water’s attempts to work with Boulder County, the reasons that federal law preempts Boulder County’s claimed authority over the FERC-licensed expansion project, and the basis for Denver Water’s request that the court prevent Boulder County from further delaying and derailing the project.

#ColoradoRiver’s voluntary fishing closure could be first of many in Grand due to low flows, high temps — The Sky-Hi Daily News #COriver #aridification

From The Sky-Hi News (Amy Golden):

Colorado Parks and Wildlife has asked anglers to voluntarily avoid fishing on the Colorado River between Kremmling and Rifle — and more voluntary closures could be coming.

The closure is in effect until further notice with a possibility of a mandatory emergency closure to all fishing if conditions worsen…

Heat, drought and low water levels are contributing to elevated water temperatures in much of Colorado, depleting oxygen levels and leaving trout vulnerable. Trout are cold-water fish that function best in 50-60 degree waters. When temperatures exceed 70 degrees, they often stop feeding and become more susceptible to disease.

As the aquatic biologist for CPW’s Hot Sulphur Springs office, Jon Ewert has seen already seen the local impact to the fishery firsthand. After a number of public reports of fish mortality along the Colorado River, he recently floated from Radium to Rancho del Rio to verify the issue. On that float, he counted 15 fish carcasses…

River flows have been exceptionally low this year.

The USGS gauge on the Colorado River at Catamount Bridge has been measuring 600-700 cfs, less than half what is historically expected there. The USGS gauge on the Colorado River near Dotsero is running at 1,250 cfs, down from an expected 3,000-4,000 cfs.

Mixed with high temperatures, these conditions spell disaster for the fishery. And it’s not just the Colorado River downstream from Kremmling.

According to Ewert, temperatures for other river sections in Grand are also edging toward dangerous levels for fish…

Ewert explained that these types of voluntary closures on rivers are not unheard of, but the extent of the closures might be…

Around 60% of Grand County’s water is diverted, mostly to the Front Range, with the Denver metro area receiving about 20% of its water from Grand.

In early June, temperatures were already spiking to 70 degrees on the Colorado River near Kremmling. Grand County coordinated with the Colorado River District, Denver Water, Northern Water and other partners to boost water levels where possible…

Denver Water estimated that by early July it will have voluntarily foregone collecting around 11,000 acre-feet of water from Grand County…

Northern Water said it has bypassed more than 6,000 acre-feet or about 2 billion gallons of water this year that has been sent downstream in the Colorado River…

Representatives of the Grand County Learning By Doing Cooperative Effort, the partnership of Front Range and West Slope water stakeholders, said that coordination is underway to release additional flows to mitigate temperatures.

While these voluntary efforts by those with water rights in Grand are helping, the sharp contrast in water use is hard to ignore for those invested in the health of the county’s rivers.

“Here’s what really breaks my heart: The Front Range water diverters filled their reservoirs … they continued to divert as much water as they did in a wet year,” [Kirk] Klanke said. “They don’t seem to feel they have any more wiggle room to leave a little more water in the river …

“Now we’re at the mercy of senior water right calls downstream. As I watch my guide friends become unemployed, I watch Kentucky bluegrass be watered on the Front Range. It’s hard to swallow.”

Hot, dry conditions stressing Grand County waterways — News on Tap

From Denver Water (Jay Adams):

Denver Water cuts back on some of its West Slope supplies to help struggling streams.

The Colorado River is hurting.

The struggles of the river’s largest reservoirs, Lake Mead and Lake Powell, have been well documented over the last decade as drought has ravished the West.

The story, however, starts more than 500 miles upstream in Grand County, Colorado.

The county is filled with streams that make up the beginning of the mighty Colorado’s journey in the mountains north of Grand Lake. Around 60% of the water in Grand County is diverted from these streams and used for agricultural and municipal water supply, mostly on the Front Range.

That includes the Denver metro area, which receives about 20% of its water from Grand County, where Denver Water has water rights dating back to the 1920s. Most of the water is captured in rivers and streams around Winter Park when mountain snow melts in the spring.

But, after a lackluster runoff season on the West Slope combined with dry soils from the past year, the hot, dry conditions in early June meant the high-country rivers and streams needed help.

Denver Water responded by voluntarily reducing diversions from several Grand County creeks and coordinating with the Colorado River District, Grand County, Northern Water and other Learning By Doing partners to adjust operations, where possible, to help boost water levels in some of the more troubled areas.

“While our primary responsibility is to make sure we’re supplying water to 1.5 million people in the metro area, we’re always looking for opportunities to help improve conditions on the rivers, to help the aquatic environment, recreation and communities they flow through,” said Nathan Elder, Denver Water’s manager of water supply.

By reducing diversions, Denver Water foregoes collecting a portion of water it is legally entitled to collect for its water supply in exchange for improving streams and tributaries along the Colorado River.

It started with a plea for help

On June 5, the Colorado River District asked Denver Water for help after reporting extremely low water levels and critically high water temperatures on the Colorado River. The river district reported conditions were creating unhealthy habitat for fish and aquatic insects.

“When the email came in Saturday morning, we were in a position to quickly respond and reduce the amount of water we were pulling from several Grand County creeks,” Elder said.

Denver Water has continued making operational adjustments since that email.

The utility estimates that by early July it will have voluntarily foregone collecting around 11,000 acre-feet of water from Grand County to help keep more water in the Colorado and Fraser rivers. That’s roughly enough water to supply over 44,000 residences for one year.

“It has been helpful to hear directly from stakeholders in Grand County, including Trout Unlimited and ranchers along the river, on where we may be able to truly help the river, the community and the environment with our operational adjustments,” Elder said.

“With help from the West Slope, we’ve been able to target specific areas and send some beneficial water downstream.”

This includes adjusting water releases from Williams Fork Dam twice a day in a way that also benefits the Colorado River.

For example, when releasing water from the dam, Elder and his team try to time the flows, so the water reaches the river in Kremmling — an area prone to higher river temperatures — during hotter times of the day.

The higher water level helps to cool down the water, which is better for the aquatic environment.

Position to help

The wet spring conditions along the Front Range boosted water supplies in Denver Water’s South Platte River collection system, which drastically reduced customers’ demand for water across the metro area — where Denver Water serves a quarter of the state’s population.

In fact, from January to May, Denver Water’s customer water use hit a 50-year low across the metro area, despite nearly 600,000 more people in its service area since 1970. That includes years in which the metro area was on mandatory drought restrictions.

“Some of the low use may be due to COVID-19 impacts on business and obviously a wet, cool spring helped,” said Greg Fisher, demand manager for Denver Water.

“It’s a great sign that our customers really understand efficient water use and let Mother Nature do the watering for them when possible.”

This wet spring on the Front Range also helped provide additional flexibility on how Denver Water collected and distributed water across its collection system during the spring snow runoff.

“We were able to turn off the Roberts Tunnel in April, which helped bring water levels up in Dillon Reservoir for boating,” Elder said.

“The conditions also enabled us to send more water down the Blue River below Dillon Dam to help improve fish habitat around Silverthorne instead of sending the water to the Front Range.”

Denver Water uses the Roberts Tunnel to bring water from Dillon — the utility’s largest reservoir — under the Continental Divide to the Front Range.

But flexibility like this is not always possible, especially with the myriad threats Denver’s water system is facing.

“Between the rising temperatures, changes to the timing of spring runoff, extreme fire behavior and half a million more people expected in the metro area by 2040, our ability for flexible operations is decreasing in a time when we need it the most,” said Elder.

“We must take an ‘all-in’ approach that includes conservation, water reuse and development of new water supplies so we can continue to maximize the benefits of a large system.”

Wet conditions in the metro area during the spring of 2021 reduced demand for water for irrigation. The lower demand gave Denver Water more flexibility to fill its reservoirs and provide additional water for environmental benefits on the West Slope. Photo credit: Denver Water.

More flexibility

According to Elder, hot, dry weather conditions highlight the benefits of having a large water collection system, as it provides the water planning team more flexibility in its operational playbook.

The vision for the Gross Reservoir Expansion Project, which is in its final steps of permitting, is an example of how additional water storage can really help streams in times of drought.

“As part of the Gross Reservoir Expansion, some of the voluntary things we’re doing this year — like leaving more water in the Grand County rivers — will become required annual operations for us,” said Elder.

That’s because Denver Water is one of 18 partners who signed the Colorado River Cooperative Agreement in 2013, ushering in a new era of cooperation between the utility and West Slope stakeholders, all with the vested interest in protecting watersheds in the Colorado River Basin.

As part of that agreement, a process called “Learning by Doing” was created, which has helped the utility stay better connected on river conditions in Grand County. The partnership is a collection of East and West Slope water stakeholders who help identify and find solutions to water issues in Grand County.

“Denver Water has been part of Grand County for over 100 years, and we understand the impact our diversions have on the rivers and streams,” said Rachel Badger, environmental planning manager at Denver Water.

“Our goal is to manage our water resources as efficiently as possible and be good stewards of the water — and Learning By Doing helps us do that.”

From Aspen Journalism (Lindsay Fendt):

The Colorado River Water Conservation District at a board meeting [January 19, 2021] voted to give $1 million of their taxpayer-raised funds to help construct the Colorado River Connectivity Channel, which will improve deteriorated conditions at the headwaters of the Colorado River.

“When I look at this, it has benefits that are assisting our communities in the damage caused by transmountain diversions,” River District General Manager Andy Mueller said during the meeting.

The district’s vote is the first step in a final push to fund and build the long-awaited channel, which has been in the works since the early 2000s. The connectivity channel is the first project to which River District board members have allocated money as part of the organization’s new Project Partnership Funding Program.

Restoring a river channel in the Upper Colorado Basin

If built, the channel would mitigate much of the damage to the Colorado and Fraser rivers that has been caused by the Windy Gap reservoir in Grand County. While the channel itself has broad support, its fate is tangled in that of a more controversial project that will draw additional water from the Colorado River system.

The Berthoud-based Northern Colorado Water Conservancy District constructed the original Windy Gap Project in the 1980s to divert water from the Colorado River to customers across the Continental Divide.

“It’s an unchanneled reservoir, meaning that it’s just plopped right in the middle of the Colorado River,” said Mely Whiting, the legal counsel for Trout Unlimited. “It basically blocks the river all the way across, and that has serious consequences.”

The project cut off the river’s flow and led to large stretches of river that went dry. It caused sediment buildup and a documented decline in biodiversity below the reservoir, including a 38% loss of its aquatic insect species and declines in fish populations.

The connectivity channel, which is designed to undo some of this damage, would reconnect the Upper Colorado and Fraser rivers to the main stem of the Colorado by routing the river around the dam of the Windy Gap Reservoir, creating a path for fish, water and sediment to flow down the river.

Since the release of its original conceptual design in the early 2000s, the connectivity channel has seen its estimated costs grow from about $10 million to $23.5 million. The River District money would help close the remaining $7 million funding gap — but not completely. According to Mueller, the River District voted to give the money in hopes that it would entice other groups to do the same.

The project has been lauded as a rare example of collaboration in the world of water management. It carries support from an unusual coalition of environmental groups, local government and water-management groups on both sides of the Continental Divide. The River District is just one of 10 of the project’s financial backers, which include Northern Water, Grand County and the Natural Resources Conservation Service.

But the channel’s construction does come at a cost. Much of the funding for the project depends on the construction of the Windy Gap Firming Project — an expansion of the Windy Gap Project that would result in the construction of a 90,000-acre-foot reservoir in Larimer County.

To date, the Windy Gap’s junior water right has meant that the project’s managers have not been able to divert water in dry years and have not had a place to store water for their customers during wet years. The reservoir would give the project’s customers a consistent supply — or “firm yield,” as it’s called — of 30,000 acre-feet annually.

Drawing additional water from the beleaguered Colorado River was controversial, so to win support for their plan, Northern Water signed on with a battery of agreements with environmental groups and Western Slope municipalities and water managers.

Included in these agreements was $5 million for the connectivity channel, a guarantee to maintain a minimum streamflow below the dam, construction of water storage for Western Slope communities and a promise to open negotiations over other water rights that impact the Western Slope.

This graphic from Northern Water shows the lay out of the Windy Gap Firming Project. The River District has voted to spend $1 million on the Colorado River Connectivity Channel, an aspect of the project meant to mitigate impacts from the dam and reservoir.

Environmental mitigation

For many groups that traditionally oppose moving water from the Western Slope to the Front Range, the benefits from the project were enough to win them over. Additional supporters and sponsors of the project include Trout Unlimited and the Grand Board of County Commissioners.

“We have to look at this in a realistic light,” Mueller said of the compromise. “This won’t fix the original sin of placing the Windy Gap Reservoir right in the middle of the Colorado River channel, but it does mitigate it.”

Trout Unlimited has used the funds from Northern Water as leverage for attracting other funding and grants for the connectivity channel and other projects to improve the habitat quality on the river. These include plans to protect the river from some of the effects of climate change by narrowing parts of the river channel to lower stream temperatures and adding fire protection.

“Everything that we’re doing is to make the river more resilient,” Whiting said. “It’s not going to be what it would be naturally in terms of size and volume and flows, but it will function naturally and it will function as good habitat in spite of all those limitations.”

But while many have heralded the Windy Gap Firming Project as the beginning of a new era of cooperation in water management, not everyone agrees that mitigating environmental damage to the river is enough.

“We are past the point where we can do work around the margins,” said Jen Pelz, the Wild Rivers Program Director for the environmental group WildEarth Guardians. “There is a climate crisis, there’s a water crisis. These things are real, and they are not going away by us mitigating them around the edges.”

WildEarth Guardians is one of six environmental groups, including the Sierra Club and Save the Colorado, that filed a lawsuit against the Windy Gap Firming Project. The 2017 suit against the U.S. Bureau of Reclamation and U.S. Army Corps of Engineers alleged that the agencies violated the National Environmental Protection Act and the Clean Water Act by approving the permits for the Windy Gap Firming Project. Northern Water was not a defendant in the case.

In the lawsuit, the environmental groups argued that the agencies did not consider conserving water instead of building a diversion project as an alternative for providing water to Front Range communities.

The call for conservation came as a surprise to Northern Water, which used the state’s water-demand projections to justify the need for their project. Those projections already assume that municipalities will adopt a certain level of conservation measures.

“We’ve been pretty confident with our project that we addressed all the issues in our environmental work that they had questions about,” said Jeff Drager, Northern Water’s director of engineering. “And part of the reason they take so long is because the federal agencies are nervous about getting sued like this, and they want to make sure they check all their boxes and get things done.”

A federal judge dismissed the lawsuit in December. In his ruling, the judge did not analyze water conservation as an alternative. Instead, he noted that the agencies followed the procedural laid out in the law and that he was required to give deference to the agencies’ decisions.

While the plaintiffs weigh whether to appeal the case, Northern Water and the other supporters of the Windy Gap Firming Project have begun taking small steps toward constructing their projects. Barring another legal challenge, they will begin construction on the project’s reservoir as soon as this summer and on the connectivity channel in the fall.

For now, the supporters of the firming project are excited about what they see as a paradigm shift in water management: a move toward cooperation over competition for water resources. Those against the project also are hoping for an eventual shift, but their idea of what that looks like is something more dramatic.

“This just highlights for me that federal environmental laws aren’t really working anymore. When you have deference to the agency, it’s hard for someone else to come in and say that here are other ways that this can be done,” Pelz said. “I think one of the things that needs to happen, which is a radical thing, is that we need to actually live within the river means.”

From The Colorado Daily (Deborah Swearingen):

The Boulder County Community Planning and Permitting Department’s review of a planned expansion of Gross Reservoir in western Boulder County is underway, officials announced Thursday.

This is the latest in a years-long dispute between Boulder County and Denver Water, who owns and operates the reservoir and dam. A Boulder District Court judge in December 2019 affirmed the county’s right to require that Denver Water go through its 1041 land use review process in order to expand the reservoir…

“Denver Water put in a request to determine if the expansion project would be exempt from our land use code,” Boulder County spokesperson Richard Hackett said.

However, the water utility company in July dismissed that appeal soon after the Federal Energy Regulatory Commission granted approval for Denver Water to continue with design and construction after the county told the company it would not conduct the review while the litigation was ongoing. The regulatory commission’s approval stipulates that project construction begin within two years. The project in 2017 received the other permit it needed from the U.S. Army Corps of Engineers…

No public meetings or hearings have been scheduled yet, but the county will announce them to its Gross Reservoir Expansion Project news list. People who want to receive emailed or text messaged notifications can sign up at here. Hackett said the agencies reviewing the application have until Oct. 14 to return initial comments, although the county has the right to extend that deadline due to extenuating circumstances caused by the coronavirus.

In the meantime, community members can submit questions or written comments to grossreservoir@bouldercounty.org. There is no deadline for doing so. Comments will be accepted until the Boulder County Board of Commissioners makes a decision.

Here’s a guest column from Stacy Chesney that’s running in The Sky-Hi Daily News:

When it comes to collaboratively managing water supplies on the West Slope, Denver Water understands that we must walk the talk.

When talking about our new era of doing business, Denver Water’s CEO/Manager Jim Lochhead regularly cites that “instead of platitudes, politics or parochialism, you need to sit down and work together.”

And that is exactly what has happened since the signatories of the Colorado River Cooperative Agreement sat down on Sept. 26, 2013, to put the new framework into action that ultimately benefits water supply, water quality, recreation and the environment on both sides of the Continental Divide.

From it came the Learning By Doing cooperative effort to maintain and enhance the aquatic environment in Grand County, which has already seen huge successes in the Fraser Flats River Habitat work, stream sampling programs and the removal of 2,500 tons of traction sand from Highway 40 before it could impact water quality and trout habitat downstream in the Fraser River.

We’re also aware that dry and hot summers, like we saw in 2018 and are experiencing again this year, bring added stress to the fisheries, environment and ultimately the entire communities of Grand and Summit counties.

When the rivers are low, talking the talk also becomes imperative.

Water efficiency is always top of mind for the Denver metro area, and during times like this, conservation dominates our communication channels. If you live on the West Slope, you may not see Denver Water’s communications about efficiency, but we are focusing on conservation measures and fostering appreciation for our source water where it matters: our customers.

We know that using less water means more water can be kept in the reservoirs, rivers and streams that fish live in and Coloradans enjoy. And ultimately, Denver Water’s customers are answering that call despite enduring what is turning out to be one of the hottest and driest years on record.

Overall, residents of the Denver metro area are using less water than they did in other summers when it was similarly hot and dry. We see them being cautious and judicious with their water use and adjusting based on the weather. In fact, Denver Water customers cut their water use in half in a matter of days when it snowed earlier in September.

This is nothing new though. After the 2002 drought, Denver Water’s conservation campaign led to our per-person reduction goal of 22% from pre-drought levels — one that we’ve continued to maintain since 2016. We’ve taken that momentum and are now working directly with our customers, sending water use reports along with rebates and tips to inefficient users on how to better use water wisely.

We also continue to evolve everything we do, from leading the way with new water reuse solutions, to upgrading our Water Shortage Plan – developed with feedback from our partners at Trout Unlimited, Grand County and other Learning By Doing stakeholders.

Denverites value where their water comes from. We live in this great state because of communities like Grand and Summit counties that provide resources precious to all of us. This benefit was made even more valuable because of the pandemic this year – a reality that we don’t take for granted and continually stress to the 1.5 million people we serve.

Closer but no cigar for #Denver Water — The Mountain Town News #ColoradoRiver #COriver #aridification

The Gross Reservoir Expansion Project will add 77,000 total acre feet — 72,000 for Denver Water use and 5,000 for an environmental pool that provides additional water for South Boulder Creek during low-flow periods — nearly tripling reservoir capacity.

From The Mountain Town News (Allen Best):

Utility says Gross expansion needed for water security for 1.5 million people

Denver Water has been awarded its final federal permit for expansion of Gross Reservoir but may still need a permit from Boulder County.

A permit from the Federal Energy Regulatory Commission announced today wraps up all the federal permitting needed to raise the existing 340-foot-tall Gross Dam across South Boulder Creek by 131 feet.

The dam has a hydro plant with a capacity of producing up to 7.6 megawatts.

But the most difficult permit may be the one that it still lacks: a 1041 permit from Boulder County. The Boulder Daily Camera explains that a district court decision affirmed the county’s authority to review the project under a 1973 law. That law, commonly known by his legislative bill title, gives local governments land use authority to review major projects by other governments.

Eagle County used that same authority in 1991 to deny a permit sought by Aurora and Colorado Springs to conduct a major water diversion project from within the Holy Cross Wilderness Area near Minturn and Red Cliff. The two Front Range cities fought the denial but lost and ultimately participated in a collaborative process designed to produce a more acceptable solution. That process is ongoing, with many opposed to the lighter, gentler approach. But by any measure, the current proposal in the Homestake Valley would have much less impact upon the wilderness area .

This case of Gross Dam is different in that the water being diverted only passes through Boulder County. The water would come from Grand County via the Moffat Tunnel. The county itself signed off on the expansion after a lengthy collaborative process that was in many ways modeled after what was created in the wake of the Homestake II denial.

Denver Water in this case committed to a collaborative process called Learning by Doing. The intent is to allow Denver to use its water rights in the Fraser Valley and also in the adjoining Williams Fork Valley but in ways that avoid the harshest of impacts.

The process earned Denver the support of Trout Unlimited, and also some fierce Denver critics such as Kirk Klancke, a Fraser Valley resident.

But some Fraser Valley residents continue to oppose the project. “We don’t have any more water to send to Denver,” says Andy Miller, a Fraser town trustee, as elected members of the governing council are known. “With the water that is being diverted now, we are barely keeping the system alive.”

Miller said additional diversions would mean that at times the only water in the Fraser River will be the releases from the wastewater treatment plants in Winter Park and Fraser. “That’s not enough,” says Miller, a member of the Upper Colorado River Watershed Group.

Denver began pursuing the expansion of the dam after the drought of 2002 exposed the vulnerability of water delivery to Arvada and other suburbs in the northwest metropolitan area that contract with Denver Water for supplies. The next year, Denver began the federal environmental permitting process. Denver already received approvals from the Colorado Department of Public Health and Environment and the U.S. Army Corps of Engineers in 2016 and 2017.

Colorado’s largest water provider, Denver Water provides water not just for the city’s residents but a broad swath of the metropolitan area, a quarter of the state’s 5.8 million residents.

In a statement, Jim Lochhead, the chief executive of Denver Water, said the FERC permit—it’s technically called an order—brings a comprehensive 17-year federal and state permitting process to a close.

Lochhead also characterized the project as a necessary given the increasing weather variability in a warming climate.

“The project provides the system balance, additional storage and resiliency needed for our existing customers as well as a growing population. We are seeing extreme climate variability and that means we need more options to safeguard a reliable water supply for 1.5 million people in Denver Water’s service area,” he said.

From The Boulder Daily Camera (Sam Lounsberry):

Denver Water announced Friday it earned its final federal approval to pursue the largest construction project in the history of Boulder County with its planned Gross Reservoir expansion.

If completed, the enlargement would help continue to serve a growing population in the water provider’s jurisdiction amid climate change that is clouding future supply with uncertainty, [Jim Lochhead] said…

An opening brief is due in August for the water agency’s appeal of a Boulder District Court decision that affirmed the county’s ability to review the project under what is known as local government 1041 power, which could result in its ultimate official disapproval by local leaders, or not, if they allow it to move forward…

Denver Water touted that the project has the support of environmental groups such as Colorado Trout Unlimited, The Greenway Foundation and Western Resource Advocates. It also said it has committed more than $20 million to more than 60 environmental mitigation and enhancement projects that will create new habitat and water flow protections for rivers and streams on both sides of the Continental Divide.

“We are committed to working closely with the Boulder County community to ensure safety, be considerate neighbors and retain open, two-way communication channels during this construction project,” Jeff Martin, program manager for the Gross Reservoir Expansion Project, stated in the news release. “We will continue to seek community input on topics such as traffic control plans, hauling traffic schedules, tree removal plans and other construction-related activities.”

The design phase for the Gross expansion is expected to finish by the middle of next year, followed by four years of construction, if approved. It will involve raising the existing 340-foot Gross Dam by an additional 131 feet, increasing reservoir capacity by 77,000 acre-feet, and it will include 5,000 acre-feet of storage dedicated to South Boulder Creek flows that will be managed by the Boulder and Lafayette city governments. Raising the capacity of Gross was a recommendation of environmentalists as an alternative to building a new dam, a proposal that would have created Two Forks Reservoir in the 1980s, the release said.

From The Associated Press via KUNC:

Even with federal approval, Boulder County still wants to conduct its own review under local government 1041 power, that could result in the project’s ultimate official disapproval by local leaders.

“We think that it was a well-reasoned decision from the district court and we have strong arguments in defense of the appeal,” County Deputy Attorney David Hughes said. “It’s not uncommon for local governments to use 1041 powers in review of major projects by other governments.”

Denver Water is expecting to appeal the county’s decision and provide an opening brief in August.

Gross Dam

From Colorado Public Radio (Corey H. Jones):

In 2018, some environmental groups sued three U.S. government agencies in an effort to stop the expansion. They argued that it would harm aquatic life and wildlife as well as hinder streamflows, adding that the Colorado River needs to be better protected…

Lochhead has said that Denver Water will only take extra water from tributaries during wet years, avoiding periods of drought.

It’s been a long road for the utility, which began the permitting process for the expansion seventeen years ago. Denver Water plans to finish the design next year, followed by four years of construction.

Final federal approval secured for Gross Reservoir Expansion Project — @DenverWater #ColoradoRiver #COriver #aridification

The Gross Reservoir Expansion Project will add 77,000 total acre feet — 72,000 for Denver Water use and 5,000 for an environmental pool that provides additional water for South Boulder Creek during low-flow periods — nearly tripling reservoir capacity.

Here’s the release from Denver Water:

[On July 17, 2020], the Federal Energy Regulatory Commission ordered Denver Water to proceed with design and construction to expand Gross Reservoir in Boulder County.

Seventeen years ago, Denver Water began the federal environmental permitting process that lead to approvals by the Colorado Department of Public Health and Environment and U.S. Army Corps of Engineers in 2016 and 2017.

“Obtaining the Federal Energy Regulatory Commission order to move forward with the Gross Reservoir Expansion Project brings a comprehensive 17-year federal and state permitting process — one that involved nearly 35 agencies and organizations — to a close,” said Denver Water CEO/Manager Jim Lochhead. “This order directs Denver Water to move ahead with construction to meet mandated milestones and timelines.”

“Expanding Gross Reservoir is a critical project to ensure a secure water supply for nearly a quarter of the state’s population. The project provides the system balance, additional storage and resiliency needed for our existing customers as well as a growing population. We are seeing extreme climate variability and that means we need more options to safeguard a reliable water supply for 1.5 million people in Denver Water’s service area,” Lochhead said.

The design phase of the Gross Reservoir Expansion Project is expected to wrap up by mid-2021 and will be followed by four years of construction. The project involves the raising of the existing 340-foot-tall Gross Dam by an additional 131 feet, which will increase the capacity of the reservoir by 77,000 acre-feet, and includes 5,000 acre-feet of storage dedicated to South Boulder Creek flows that will be managed by the cities of Boulder and Lafayette.

“We are committed to working closely with the Boulder County community to ensure safety, be considerate neighbors and retain open, two-way communication channels during this construction project,” said Jeff Martin, program manager for the Gross Reservoir Expansion Project. “We will continue to seek community input on topics such as traffic control plans, hauling traffic schedules, tree removal plans, and other construction-related activities.”

The FERC order, along with the permitting conditions put in place by CDPHE and the Corps, further commits Denver Water to implement environmental improvements by putting in place measures evaluated in the environmental assessment issued in February 2018.

The project relies on the expansion of an existing footprint — without the placement of a new dam, reservoir or diversion structure; it also benefits from an original design that anticipated eventual expansion. Increasing the capacity of Gross Reservoir was a specific and formal recommendation from the environmental community as an alternative to construction of the proposed Two Forks Reservoir in the 1980s.

Denver Water has committed more than $20 million to more than 60 different environmental mitigation and enhancement projects that create new habitat and flow protections to rivers and streams on both sides of the Continental Divide as a result of the Gross Reservoir Expansion Project. According to Colorado officials, those commitments will have a net environmental benefit for the state’s water quality.

This project has earned the support of major environmental groups including Colorado Trout Unlimited, The Greenway Foundation and Western Resource Advocates; local, state and federal elected officials (including Colorado’s last five Governors); and major business and economic development groups, among others.

An expanded Gross Reservoir is critical to Denver Water’s multi-pronged approach — including efficient water use, reuse and responsibly sourcing new storage — to improve system balance and resiliency while contributing to water security for the more than 1.5 million people in the Denver metro area.

The FERC regulates the production of hydropower in the United States. As a Federal Power Act project dating back to 1954, expanding Gross Reservoir required the FERC’s approval of Denver Water’s application to amend its hydropower license. This approval and order carry the force of law and are the final federal authority over the reservoir project.

The delicate dance of Dillon Reservoir during spring #runoff — @AspenJournlism #snowpack

Dillon Reservoir in Summit County is the largest reservoir in the Denver Water system, holding more than 257,000 acre-feet of water when it’s full. With two outlets — the Blue River and Roberts Tunnel — Denver Water officials say it’s complicated to operate. Photo credit: Denver Water via Aspen Journalism

From Aspen Journalism (David O. Williams):

Denver Water officials increased the release of water from Dillon Reservoir into the Blue River to about 400 cubic feet per second in the first week of May as inflow held steady at about 500 cfs through Monday, May 11. The latter number is expected to steadily rise as spring runoff picks up.

The current forecast from the National Oceanic and Atmospheric Administration’s Colorado River Basin Forecast Center estimates as of May 11 that there is 146,000 acre-feet of water — in the form of snowmelt — that will flow into Dillon Reservoir through July 31. There’s currently 17,500 acre-feet of space in the reservoir, according to Denver Water, so about 128,500 acre-feet will flow out of the reservoir either to the Blue River or Roberts Tunnel by July 31, with an estimated 13,000 acre-feet through the tunnel.

All of these complex calculations are the first steps in a delicate dance Denver Water performs each spring to balance public safety with Denver’s water needs, recreation, hydroelectric demands and obligations to downstream senior water-rights holders.

“Dillon is our biggest reservoir and one of our more complicated to operate,” said Nathan Elder, water resources manager for Denver Water. “Most of our other reservoirs only have one outlet, but Dillon’s got both the outlet to the Blue and the outlet to the Roberts Tunnel, which provides water to the East Slope and down the North Fork (of the South Platte River) to Strontia Springs Reservoir and then to our customers.”

The Roberts Tunnel, finished in 1962 about the same time the old town of Dillon was relocated to its current spot and the Dillon Dam was built, is a 23-mile concrete conduit that diverts water from the Blue River basin on the Western Slope to the South Platte Basin on the Front Range to supply more than 1.4 million Denver Water customers.

Colorado transmountain diversions via the State Engineer’s office

This system is what’s known as a transmountain diversion — one of many that bring water from the Colorado River basin on the west side of the Continental Divide to the state’s population center on the Front Range. What it’s not, Elder said, is a way to avoid dangerous spring-runoff flooding.

“We can’t use Roberts Tunnel as a flood-control option,” he said. “So we’re very careful about the amount of water we take from the West Slope over to the East Slope. And when we use the Roberts Tunnel, we can only take it over to the East Slope if it’s put towards the demand. We can’t just dump it over there to prevent flooding or high flows below Dillon.”

The 2014 Colorado River Cooperative Agreement places a 400,000 acre-foot limit on Blue River water stored in existing or future Denver Water storage facilities on the Front Range.

There are more than 1,000 properties in regulatory floodplains in Summit County, according to the Federal Emergency Management Agency, and quite a few of them are along the Blue as it makes its way northwest through Silverthorne and toward its confluence with the Colorado River near Kremmling.

Snowpack melting

This time of year, as snowpack begins to melt into local tributaries — the Blue, Snake River and Tenmile Creek all feed Dillon Reservoir from the south — Elder and his team closely monitor snowmelt forecasts and weather reports to coordinate with local officials to prevent flooding.

“Denver Water has worked with the town over the years to release water from Dillon Reservoir at rates between 50 cfs and 1,800 cfs,” said Tom Daugherty, Silverthorne’s director of public works. “They have done a very good job of doing that. Denver Water attends our local meetings concerning snowmelt runoff and inform us of what they expect.”

FEMA designates 2,500 cfs as a 10-year flood level just below Dillon Dam, while 3,350 cfs there would be a 100-year flood level. The amount of runoff pouring into the reservoir varies widely, depending on weather conditions and snowpack, from a low inflow of 410 cfs in the drought year of 2012 to a high of 3,408 cfs in 1995.

The amount of snowpack on the Front Range and rate of melting due to high temperatures or rain events also impacts when Denver Water turns on the Roberts Tunnel and how much water it takes out of Dillon Reservoir. The Blue River Decree dictates that Denver Water needs to keep as much water on the Western Slope as possible and can take water only to meet demand.

“Last year was a good example of that,” Denver Water spokesman Todd Hartman said. “We had so much snowpack on the Front Range that we just didn’t need the Roberts Tunnel water and couldn’t take it because of that demand issue.”

That resulted in higher flows on the Blue below the dam last runoff season.

“It got up to around 1,900 cfs, and we didn’t actually turn on the Roberts Tunnel until the second week in August last year,” Elder said. “That’s after everything on the East Slope filled, and we started dipping into that storage and streamflow dropped off on the East Slope.”

This year, there’s a similarly healthy snowpack above the reservoir and also decent snowpack on the Front Range, but temperatures have been higher and the spring runoff season hasn’t been nearly as wet and cool as last year.

“We have a Snotel (snow telemetry) site on top of Hoosier Pass, which is extremely important for monitoring that basin and for forecasting, and it’s still at 121% of normal right now,” Natural Resources Conservation Service hydrologist Karl Wetlaufer said in early May. “It looks like it did actually have a net accumulation through April and is just really just starting to turn around and melt out now over the last few days with this warm weather.”

The Natural Resources Conservation Service produces snowmelt forecasts used by Denver Water, which also taps into the National Oceanic and Atmospheric Administration forecast center.

Based on information from Snotel sites, snowpack above Dillon Reservoir peaked at 127% of normal. The forecast center’s inflow outlook for Dillon Reservoir is 104% of average, and the forecast from the Natural Resources Conservation Service was 107% of average.

The first priority for Denver Water is to fill the reservoir to meet customer needs, but it also tries to minimize high flows out of the reservoir via the Blue River and maintain water levels so that the Frisco and Dillon marinas can operate from June through Labor Day. Elder said the minimum operating level for both Dillon and Frisco marinas is 9,012 feet in elevation.

The goal, Elder said, is to get the reservoir to that level or higher by June 12. On May 11, the surface level of the water in the reservoir was at 9,010 feet. The reservoir is full when the elevation of the water, as measured on the dam, is 9,017 feet, which is 257,304 acre-feet of water. At 9,010 feet, the reservoir is holding about 236,232 acre-feet of water.

Release too much and too early — to avoid high flows and flooding downstream — and Denver Water runs the risk of missing the chance to fill Dillon for use by its customers later in the summer season as well as keep the reservoir full for a long boating season. And then there are the downstream hydroelectric factors and calls by senior water-rights holders.

Senior water rights

While the Blue River Decree does not have a volumetric limit on how much water Denver Water can take out of Dillon Reservoir through the Roberts Tunnel to meet its customer needs, the Roberts Tunnel right is from 1946 and is junior to Green Mountain Reservoir and Shoshone Power Plant rights, which limit the ability of Denver Water to divert. The Roberts Tunnel right is for 788 cfs, which is not a storage right but instead a direct-flow right.

So if Green Mountain gets toward the end of its fill season and hasn’t filled and Dillon has diverted, then Denver Water owes water to Green Mountain. Green Mountain Reservoir, located on the Blue River in northern Summit County, was created specifically to compensate the Western Slope for diversions to the Front Range as part of the Colorado-Big Thompson Project.

Then on the Colorado River in Glenwood Canyon, well downstream from where the Blue feeds the Colorado at Kremmling, there’s Xcel Energy’s Shoshone Generating Station hydroelectric plant — which has one of the most senior water rights on the main stem of the Colorado River. A 1902 right draws 1,250 cfs of water downstream to meet the plant’s needs. During dry times of the year, such as late summer, the power plant often places a “call” on the river, meaning junior diverters upstream — including Denver Water — must stop diverting so that Shoshone can get its full allocation of water.

Elder said Denver Water wants to fill Dillon Reservoir quickly enough each spring before any potential Shoshone call. If a call came before Dillon was full, Denver Water would have to release water from Williams Fork Reservoir in order to keep water in Dillon Reservoir. However, Williams Fork can hold only 96,000 acre-feet of water.

“We want (both reservoirs) to fill quick enough that we fill both before that Shoshone power plant call comes on and before the senior call comes on the river, but not too quick that we fill before peak runoff where we get in those high-flow situations,” Elder said. “So it’s a real balancing act there. You’re balancing elevations for marinas, downstream water rights, filling the reservoir safely and then also any potential releases you may need to make from Roberts Tunnel.”

#ColoradoRiver Water Users Association Annual Conference recap: “ClimateChange is #water change” — @BradUdall #CRWUA2019 #COriver #DCP #aridification

From The Sante Fe Reporter (Laura Paskus):

Water wonks, state and tribal officials, attorneys and irrigation district representatives hit the floor at Bally’s Las Vegas Hotel last week. Not to shake loose the slots. But to gamble on the future of the Colorado River.

During the annual meeting of the Colorado River Water Users Association (CRWUA), stakeholders from the seven US states that share the river’s water met to talk about everything from interagency cooperation to cloud seeding, forecasting to tribal water rights.

But even as the impacts of the Earth’s warming are increasingly clear, there’s still a political and practical disconnect between the cause of climate change—the burning of fossil fuels—and the challenges warming poses to water supplies in the western United States.

That decoupling was hammered home by US Department of the Interior Secretary David Bernhardt, who spoke at the CRWUA meeting. During his keynote speech, Bernhardt avoided mentioning climate change.

When pressed by reporters afterwards, he said he “certainly believe[s] the climate is changing.” But he cautioned that forecasting is speculative.

David Bernhardt answers a question about climate change from Luke Runyon, December 13, 2019, Colorado River Water Users Association Annual Conference.

And he praised the role energy development plays in states like New Mexico.

“The president was very clear when he ran for office on his position on energy; he’s for an all-of-the-above approach,” Bernhardt said. “In New Mexico last year, we sent $1.7 billion from federal lands to the state of New Mexico that went to schools and other things. So, when people tell me they want to stop oil and gas development on federal lands, I say ‘Call the governor of New Mexico.'”

Gov Michelle Lujan Grisham’s office could not answer SFR’s questions by deadline about Bernhardt’s claims related to revenues from drilling on federal land in New Mexico and balancing the disconnect between the state’s energy policies—which have spiked revenues—and emissions from that industry, which exacerbate the state’s water challenges.

The governor’s spokeswoman also could not provide a response to Bernhardt’s statements before deadline…

Brad Udall: “…latest version of my 4-Panel plot thru Water Year (Oct-Sep) of 2019 of the #coriver big reservoirs, natural flows, precipitation, and temperature. Data goes back or 1906 (or 1935 for reservoirs.) This updates previous work with
@GreatLakesPeck

In 2017, a peer-reviewed study showed that warming was already causing flows on the Colorado River to decline. Between 2000 and 2014, flows averaged 19% below the 1906-1999 average, and scientists found that one-third of those losses were due to higher temperatures, rather than changes in precipitation. They also wrote that if warming continues, the Colorado River’s flows will drop even more—20 to 35% by 2050, and 30 to 55% by 2100.

A follow-up study in 2018 showed that even though annual precipitation in the Colorado River Basin increased slightly between 1916 and 2014, flows declined by 16.5 % during that same time period—due in large part to “unprecedented basin-wide warming.”

“Climate change is water change,” says Bradley Udall, one of the co-authors of both those studies. Udall is a senior water and climate research scientist at the Colorado Water Institute at Colorado State University.

In arid landscapes like the US Southwest, warming affects river flows, snowpack, soil moisture and even the amount of water crops and forests need to survive.

“In our case, [climate change] means these longer, hotter droughts that threaten the Rio Grande and the Colorado River system in ways that are unprecedented,” Udall tells SFR.

“If you’re going to reduce the risk of water shortages for humans and nature, you’ve got to solve the climate change problem.”

And, he says, solving the climate change problem means stopping fossil fuel production: “You can’t solve climate change if you’re going to continue to pursue fossil fuel production willy-nilly.”

And yet, drilling is booming across the world, including in New Mexico. And that development has consequences.

Per capita annual carbon dioxide emissions and cumulative country emissions. Data from the Global Carbon Project. Nature. Data from the Global Carbon Project

Earlier this year, the World Meteorological Organization showed that carbon emissions have continued to increase. According to a story in the BBC, “Using data from monitoring stations in the Arctic and all over the world, researchers say that in 2018 concentrations of CO2 reached 407.8 parts per million (ppm), up from 405.5ppm a year previously. This increase was above the average for the last 10 years and is 147% of the “pre-industrial” level in 1750.” Not only that, but methane emissions continue to rise, as well—and is now at 259 % what it was before the Industrial Revolution.

Meanwhile, global temperatures continue to ruse. The latest numbers from the National Oceanic and Atmospheric Administration show that the three-month season of September through November 2019 ranked second-warmest on record for the globe—with a global temperature of 1.69°F above average. Already, New Mexico’s average annual temperature has increased by 2°F—just since the 1970s.

Continued warming will have continued impacts across the US Southwest. And even after last winter’s robust snowpack, the basin’s reservoirs, system-wide, sit at just over half-full. The two largest reservoirs, Lake Powell and Lake Mead, are 52 % and 40 % full, respectively. A second year of good snowpack, Udall estimates, would put the system at perhaps 60 % full…

Asked to rectify that with the president’s statements about climate change as a “hoax” and his attacks on climate science, Bernhardt reiterated that Trump has been an “exceptional leader on western water issues.”

“I think it’s very hard to go back and find presidents who have given clear direction in memos to the secretaries, [that] say ‘Get on with it. Solve these situations,'” he said, referring to Trump’s 2018 presidential memorandum on reliable water supplies in the western US. In that memo, the White House directed federal agencies, including Interior, to “work together to minimize unnecessary regulatory burdens and foster more efficient decision-making so that water projects are better able to meet the demands of their authorized purposes.”

Bernhardt also directed the US Bureau of Reclamation to launch its review of the 2007 interim guidelines at the beginning of 2020.

From The Las Vegas Review Journal (Shea Johnson) via The Boulder City Review:

U.S. Bureau of Reclamation Commissioner Brenda Burman said Dec. 11 that Nevada has been a national leader in water conservation by reducing demand on the Colorado River and investing in infrastructure over the past two decades.

In Las Vegas for the Colorado River Water Users Association’s annual conference, Burman declined to say, however, whether she sees Nevada’s share of the river’s water increasing, even though it draws the least amount of water than any other state.

Instead she said Mexico and seven Southwestern states served by the river were focused on working within the existing rules and regulations, known as the “Law of the River.”

In an interview with the Review-Journal, Burman said that “desalination is going to be part of the answer” to reducing draws on the river, noting that California has already made major investments on that front, and talks between Mexico and lower basin states have questioned whether desalination is possible in that country.

“We all really need to be looking at an all-of-the-above approach,” she said about viable long-term solutions to river sustainability…

The three-day annual conference culminated with a tour of Hoover Dam with federal officials. It followed a keynote speech by Secretary of the Interior David Bernhardt.

Gross Reservoir Expansion Project update

Gross Dam enlargement concept graphic via Denver Water

From TheDenverChannel.com (Jace Larson):

The project will require significant construction over seven years to increase the reservoir’s holding capacity to 119,000 acre-feet of water.

When built, the dam will be the tallest in Colorado.

Denver Water says the additional space is needed to spread out capacity outside of Denver for the water utility used by 1.4 million people in the city and its surrounding suburbs.

The proposed construction project is not without opposition from neighbors and environmentalists who say they will endure years of construction on a water project that will never provide water to their taps.

“Boulder County is going to host this reservoir but gets no water from it. We derive no benefit from it. We only pay the price of having this thing in our county,” said Tim Guenthner, who lives just above the dam in a subdivision of about 1,000 people.

Denver7 decided to take a 360 look at this issue and gathered perspectives from five people connected to the proposed construction project…

Boulder County Commissioners have also taken a stance that Denver Water must get local permits before it can start the project.

Denver Water spokesman Travis Thompson said Denver Water doesn’t believe the law requires that and points out it has undergone numerous environmental studies and worked through the state permit process. This issue will likely be decided by another judge…

Denver Water’s Gross Dam project manager, Jeff Martin, acknowledges the project will cause noise for neighbors.

“Well we don’t hide from the fact there’s going to be some disruption from the noise, but we are looking at ways of minimizing that noise,” Martin said.

As an example, Denver Water decided to move the quarry needed to make cement to a portion of the lake that will be covered by water once more capacity is added. The original plan had the quarry on a portion of land jetting out into the lake.

Have an on-site quarry will also mean less truck traffic.

Martin said even with conservation efforts, Denver Water needs more capacity. He said experts have provided the water utility with data showing there will be 5 million more people in Colorado by 2050.

Denver water has 90% of its storage lakes west and south of the metro area, but only has 10% up north. This new dam project will add significantly more water storage north of the city.

“That’s important because if we have a catastrophic event or a drought in one of the systems, it leaves us depending on the other system,” he said. “What we want to do is create a little bit more balance and put more water in Gross Reservoir. This project is going to triple the size of the reservoir.”

[…]

Kirk Klanke is a member of Trout Unlimited, an environmental group seeking to protect and restore rivers across the country.

His perspective is one many wouldn’t expect from a member of the environmental group. He’s a supporter of the new dam.

“I think it’s extremely selfish to think we shouldn’t grow,” he said.

He says Denver Water has the legal right to build more capacity someplace. Gross Reservoir is the best option.

“Raising an existing dam has far less environmental damage than building a new one somewhere else,” Klanke said.

He says Denver Water has agreed to put significant effort into protecting the Colorado River. When it is hot out, river temperatures rise if there’s only a little water flowing.

Denver Water has agreed to keep water in the river during those periods and fill the lake during spring runoff. It will also draw water at different places in the river to minimize the impact to one area.

Moffat Collection System Project update: “Our problem is rooted in demand and resiliency” — Jeff Martin

From The Colorado Sun (Amanda K. Clark):

Raising the 55-year-old dam near Boulder is essential to keep a stable water supply in a changing climate, utility says. Residents insist conservation could be just as effective.

Denver Water — Colorado’s largest and oldest utility company — in July 2017 received one of the final permits needed to raise Gross Reservoir Dam by 131 feet to increase water storage capacity by 77,000 acre-feet, or an additional 25 billion gallons of Western Slope water…

The expansion, in the works for more than a decade, is part of the company’s long-term plan to help meet increasing water demands along the Front Range and buffer customers from future water-supply variability due to climate change…

Denver Water has been met with sustained opposition from Boulder County residents and a handful of environmental groups who say the utility can address its water needs through expanded water conservation efforts on the Front Range.

But with Colorado’s population growth showing no signs of slowing, water conservation may be inadequate to address projected shortages in the coming decades.

Other concerns raised by opponents include sustained disruption to surrounding residents, increased traffic, health concerns and environmental impacts to fish and wildlife.

Gross Reservoir is filled primarily from snowmelt that flows from the Fraser River, a tributary of the Colorado River. The water is transported underground from west of the Continental Divide to the east by a pipeline called the Moffat Water Tunnel.

The controversy over the Gross Reservoir expansion, estimated to cost $464 million, echoes an all-too-familiar story: a highly contentious discussion of tradeoffs that has rippled across the Western United States for decades.

As cities and states across the West grapple with swelling population alongside diminishing water supplies as a result of climate change, water-resource agencies such as Denver Water are faced with the delicate task of balancing the health of ecosystems with municipal, agricultural and recreational needs…

Jeff Martin, Denver Water’s project manager for the expansion project, doesn’t skirt around the controversy. He recognizes that the project is going to cause disruption and says that Denver Water has worked with the residents to find ways to minimize the project’s impact.

“This has been a process,” Martin said. “We started in 2004, it took 13 years to move through the environmental assessment and permitting process. And we’ve made a lot of changes and adjustments to our plans since the beginning.”

“No single solution is out there,” he said. “Our problem is rooted in demand and resiliency, and what I mean by resilience is that we have to make sure we have the water when we need it, and where.”

[…]

For Patty Limerick, director of the CU Boulder’s Center for the American West and former Colorado Historian, you can’t talk about water issues on the Front Range without first looking back in time.

When early white explorers arrived here, they deemed the Front Range unfit for settlement due to lack of water. Today, 1.4 million Denver residents have access to clean drinking water due in large part to Denver Water’s enormous infrastructure web that diverts water from the South Platte, Blue, Williams Fork and Fraser river watersheds to be stored in a network of reservoirs spread over eight counties, including Dillon, Strontia Springs and Cheesman.

“One thing that I find fascinating, and is important to talk about, is the incredible amount of engineering that had to occur to make any of this possible in the first place,” Limerick said.

“We, as a society, have to recognize the improbable comfort that was made possible by a taken-for-granted, but truly astonishing, water infrastructure that was put in place a hundred years ago.”

[…]

“The year 2018 was very similar to what we would expect to see under a climate change regime. And that was a very intense but short-term drought,” said Taryn Finnessey, senior climate change specialist with the Colorado Water Conservation Board.

“We saw some reservoirs in the state declined by 50 percent in a three- to four-month period. So that obviously could not be sustained multiple years in a row,” she said. “Water providers are increasingly integrating climate change models into their water supply projections. They know that what we’ve seen in the past might not fully represent what we might see in the future. Denver Water is one of the more advanced utilities when it comes to this.”

Finnessey says it’s not just about how much precipitation falls from year to year. It also has a lot to do with increasing temperatures, contributing to the long-term drying out of the West, a phenomenon scientists are referring to as aridification. As temperatures rise, more moisture is sucked up by the atmosphere through evapotranspiration, leaving less viable water for humans-use in the system.

“We are planning for infrastructure that will be built in the next 20 years, that is supposed to last for the following 100 years,” said Reagan Waskom, director of Colorado State University’s Colorado Water Institute. “Our world is changing significantly faster than that. And not in a linear way. How do we adapt to that?

“Water managers have to plan for extremes,” he added. “A year like this year is an argument for reservoirs. Even with climate change, you’re still gonna have some good years. And we need to be able to capture it and save it for the bad years, whether that’s in underground aquifers or in reservoirs.”

Gross Reservoir expansion makes sense — Boulder Daily Camera

From the editorial board (Quentin Young) of the Boulder Daily Camera:

Denver Water serves 1.4 million people in Denver and surrounding communities, and that figure will rise substantially in the coming decades. As more residents demand service, climate change increasingly will exert its own strain on the water supply. One of the primary ways the utility plans to meet this imminent challenge is by expanding one of its northern storage facilities, Gross Reservoir, in the foothills southwest of the city of Boulder.

The project has met with intractable opposition. It’s the subject of lawsuits and uncertain government reviews. Neighbors are scandalized by the prospect of years of disruptive construction, and some environmentalists contend the project won’t even be able to perform its intended purpose.

But a dispassionate consideration of the project leads to the conclusion that Denver Water’s plan to expand Gross Reservoir is a reasonable and responsible measure, provided the utility proceeds with the utmost sensitivity to the residents who would be impacted by construction and with the expectation that increased storage is no substitute for continued conservation efforts.

The roots of the project go back to the proposed Two Forks Dam. Denver Water had proposed storing water from the Colorado and Platte rivers by building a 615-foot dam southwest of Denver near Deckers. But a coalition of environmental groups successfully opposed the project, which the Environmental Protection Agency spiked in 1990. Environmentalists argued at the time that a better option would be for Denver Water to expand a storage facility it already operated: Gross Reservoir.

Gross Dam enlargement concept graphic via Denver Water

Now that the utility is following opponents’ former advice, environmentalists have changed their mind about Gross. The project would raise Gross Dam by 131 feet to 471 feet, roughly tripling the reservoir’s current capacity of 41,811 acre-feet (for comparison, Denver Water’s largest reservoir, Dillon, has a capacity of more than 257,000 acre-feet). Critics say the expansion would result in the state’s tallest dam, and much of the opposition focuses on the project’s substantial environmental impact. It would require years’ worth of noisy construction, traffic and the removal of about 650,000 trees. The reservoir pulls water from the headwaters of the Colorado River, and critics argue that the utility should refrain from further depleting that waterway, which runs all the way to the Gulf of California and is subject to the Colorado River Compact, an agreement that governs water allocation in seven states that rely on the river as an invaluable resource. Population growth in the Southwest has stressed the river, and climate change is expected to further compromise the river’s capacity to deliver water to users. Some Gross expansion opponents even assert that there won’t be enough water available from the Colorado River Basin to fill a bigger reservoir. And anyway, the opponents say, water needs can be met through conservation rather than dam-building.

Construction to expand Gross Reservoir would indeed bring acute hardship to nearby residents, and concern for local environmental damage should not be dismissed. But construction is temporary, and the environmental impact seems less intolerable than merely regrettable when weighed against the project’s purpose of ensuring for decades the delivery of a vital resource to thousands of people.

Utilities should be judicious in exercising their rights to Colorado River Basin water, but the volume associated with the proposed Gross expansion is relatively small. The entire Denver Water utility accounts for less than 2% of the state’s total water use, while it serves about 25% of the population. As part of planning for the expansion, Denver Water worked with West Slope communities in the Colorado River Basin to earn support for the project, efforts that in 2012 resulted in the Colorado River Cooperative Agreement. The CRCA, which depends on final approval of the Gross Reservoir expansion, calls for Denver Water to help restore habitats and maintain flows in the Fraser River, a Colorado River tributary in Grand County. Some West Slope officials so favor implementation of the CRCA that a Grand County commissioner in March warned of “a ton of litigation” were Boulder to block the Gross expansion.

Colorado River flows will almost certainly decrease due to climate change in future decades. A widely cited 2017 study suggests the river increasingly will be subject to droughts, and flows could drop more than 35% by the end of the century because of higher temperatures. But this doesn’t necessarily constitute an argument against expanding Gross. No one can claim with certainty that flows would drop such to render useless an expanded reservoir, but Denver Water would certainly be justified in viewing the threat of persistent droughts and lower flows as a reason to increase storage capacity, since there’s more incentive to collect water during the fewer occasions it’s available. The utility would be seen to have failed customers were it to find itself with nowhere to store precious water to which it had rights.

That Denver Water should do more to promote conservation gets no argument here. The utility’s customers have already demonstrated that they can get by splendidly with reduced volume — they’re using about 20 percent less water today than 15 years ago, according to Denver Water CEO Jim Lochhead — and there’s much room for further conservation. But conservation has limits, and Denver Water says it won’t be able to meet future demand solely by this method. In Denver alone, the current population of 729,000 is expected to swell by more than 20% in just 20 years. Besides, the project is meant not just to add yield to the utility’s system but also stability. The vast majority of Denver Water’s storage is in the south part of its system, and forest fires near those facilities, such as the Buffalo Creek Wildfire in 1996, have exposed a vulnerability that an expanded Gross would address.

The proposed expansion of Gross Reservoir has provoked waves of protest from Boulder County residents, and the county has asserted what it claims is its right to review the project. Known as a 1041 process, the move is contested by Denver Water. But though Denver Water doesn’t serve Boulder-area residents, water users throughout Boulder County every day enjoy the use of water pulled from the Colorado River, and water customers in such Boulder County communities as Longmont, Louisville, Lafayette, Erie and Superior are participants in the proposed Windy Gap Firming Project, which involves the construction of a whole new reservoir, not just an expansion, west of Carter Lake to store water from the Colorado River Basin. (That project similarly is tied up in litigation.)

Denver Water has already secured the bulk of required regulatory approvals for the expansion of Gross Reservoir. A final decision from the Federal Energy Regulatory Commission, whose staff has already recommended approval, is pending. Denver Water needs the FERC approval, because Gross also serves as a hydroelectric facility. Roadblocks include a lawsuit brought by a coalition of environmental groups that is led by Save the Colorado and Boulder County’s 1041 review.

Boulder County officials have a legitimate interest in reviewing what would be the largest construction project in county history, and they are encouraged to take an exhaustive look at Denver Water’s plans. Any objections to the expansion of Gross Reservoir, however, should be based on factors intrinsic to the proposal, not on a mere preference for Gross to be left alone.

Save the Colorado is allowed to intervene in @DenverWater lawsuit v. @BoulderCounty

Workers build the Moffat Tunnel in the 1920s.

From The Loveland Reporter-Herald (Sam Lounsberry) via The Denver Post:

An environmental group’s motion to intervene in a dispute between Denver Water and Boulder County over the proposed expansion of Gross Reservoir was granted by a judge on Tuesday.

Court documents show Boulder District Judge Andrew Ross Macdonald will allow the group, Save the Colorado, to enter the case as a party on behalf of Boulder County, the defendant in the suit.

Denver Water filed the complaint against the county after it decided the utility would have to subject its controversial proposed dam expansion — which would be the largest construction project in the county’s history — through the county development approval process.

The case is still moving through court, with Denver Water trying to avoid subjecting its project to county [1041 regulations].

The Shoshone hydro plant went down, but flows in the #ColoradoRiver stayed up — @AspenJournalism #COriver

The penstocks feeding the Shoshone hydropower plant on the Colorado River in Glenwood Canyon.

From Aspen Journalism (Brent Gardner-Smith):

The Shoshone hydropower plant on the Colorado River east of Glenwood Springs was not producing power for most of last week [April 7, 2019], but regional water managers went with the flow and — thanks to an “outage protocol” — honored the plant’s senior water rights anyway.

Plant operators with Xcel Energy notified state, federal and regional water managers April 5 that they needed to inspect a leak in a diversion tunnel adit, or access point. To do so, they would be slowly shutting the flow of water to the plant’s two 7.5 mega-watt (MW) turbines and taking the plant offline.

The facility’s two-mile-long tunnel runs through cliffs in Glenwood Canyon and moves water from behind a dam on the river to the penstocks above the plant, which is just upstream of the boat ramp for the Shoshone run. The plant, which Xcel began powering down April 5, was offline by April 8.

The plant stayed offline until Friday, when the leak in the tunnel was fixed and the plant began powering back up, according to Michelle Aguayo, a media-relations representative at Xcel.

The outage at what Xcel calls the Shoshone Generating Station did not affect local or regional power customers, because other electricity on the grid system made up for the loss of the plant’s capacity, Aguayo said.

In response to the plant going offline, officials at the state division engineer’s office lifted the call on the river on April 8. If the hydro plant is not in operation, the water right tied to it is not being put to beneficial use and cannot be administered, or legally enforced.

The call for water that is tied to the Shoshone plant’s most senior water right from 1902 means junior upstream diverters have to forego storing or diverting enough water to keep 1,250 cubic feet per second of water available for the plant.

Without the call, and the outage protocol, more water could be diverted under the Continental Divide or kept in upstream reservoirs, and less would flow through Glenwood Springs.

Ruptured penstock

The outage protocol concept was prompted by the increase in outages at the Shoshone plant starting in 2004. It took on greater importance when a penstock at the plant ruptured in 2007.

The protocol was given a trial run in 2010, formalized in 2012 as part of the Colorado River Cooperative Agreement, and then signed as a stand-alone agreement in 2016.

Parties to the protocol include the Colorado River Water Conservation District, the Bureau of Reclamation, Denver Water, Northern Water, Aurora and other entities.

Protocol days

Number of days the Shoshone outage protocol, or ShOP, was in effect, and stages of the agreement.

According to Don Meyer — who is a senior water-resources engineer at the Colorado River District, which is based in Glenwood Springs — the protocol was in effect from April 8 until the call came back on the river on Sunday.

And he said it worked as intended, with the parties cooperating in an amiable manner.

“Without the outage protocol, the river probably would have been impacted,” Meyer said.

He also didn’t think most upstream operators changed how they were managing their water, because the protocol meant they were still working against a need to keep flows on the river at 1,250 cfs, even with the plant offline.

Fortuitous flows

The river rose, on its own, during the time the plant was out. But the outage protocol also helped boost flows.

The river’s level was also helped by a short warm spell that caused flows at the Dotsero gage, where the flow to Shoshone is measured, to rise above 1,250 cfs starting the day that the plant first started powering down on April 8.

By April 10, the river had risen to 1,750 cfs. But then cold weather dropped the river back under 1,250 cfs on Sunday, as forecast, just when the plant was powering back up and the call was coming back on.

If the plant had been down longer, and flows had stayed low due to cool mountain weather, the outage protocol could have mattered more to the flows in the river.

Meyer said that when the plant was offline for repairs in 2012, the outage protocol kept the river through Glenwood from falling below 1,000 cfs for about two weeks in late June of that notably dry year.

Down on the Ground in the Anthropocene City-State — Colorado Central Magazine

George Sibley

Full disclosure, I have written articles for the magazine in the past.

Here’s a look at Denver Water’s Moffat Collection System Project and the Boulder County Commissioner’s hearing on 1041 jurisdiction from George Sibley that’s running in Colorado Central Magazine. Click through and read the whole article. Here’s an excerpt:

An interesting thing happened mid-March in Boulder which the media seem to have mostly missed. Commissioners from Grand County showed up at a noisy Boulder County commissioners’ hearing on a West Slope-to-East Slope transmountain water diversion project – to testify on behalf of the project. It is probably the first time ever, in the generally contentious history of Colorado water development, that the people in a basin of origin have supported a transmountain diversion project that people in the basin of destination oppose.

Although this is a story from just beyond our Central Colorado boundaries, it is a story of interest to anyone in the West who is wondering how, or even if, we are going to finally leave the 20th century and venture into the 21st and the Anthropocene Epoch we keep trying to pretend we haven’t brought on ourselves.

The report on the Boulder County hearing sounded like your usual 20th century public hearing on the kind of issue that seems almost structured to pit environmentalists against the developers of something or other – a hearing in which no one has to listen because everyone already knows what everyone else is going to say.

The issue in this case pits the usual Front Range environmental organizations against a public utility that everyone loved to hate through the 20th century, Denver Water (DW). DW wants to enlarge the Gross Dam and Reservoir it built in the 1950s in the foothills near Boulder, to hold some additional water it wants to import from the West Slope – its “Moffat Firming Project” which would bring a third more water on average through its Moffat Tunnel Project from the Fraser and Williams Fork Rivers in the Upper Colorado River watersheds…

For the West Slope and Grand County, DW is both funding and actively participating in planning and executing a Learning by Doing process – essentially, an adaptive management process of active experimentation in learning how to live with less water. Some of it is more conventional work providing funding and expertise to water treatment districts and irrigation districts needing to use less water more efficiently.

But some of it will actually be what strikes me as “creative environmentalism”: Actually reconstructing some streams to function ecologically with a permanent reduction of water – call it “downsizing” the stream to fit the unignorable realities of the future. Channels are narrowed and deepened to cool the waters, helping both the aquatic ecosystem and the human economy of floaters and fishermen; riparian vegetation is planted to shade the stream and stabilize banks; meanders are induced to give a healthy stability and resilience for the foreseeable diminished future. Half a mile of the Fraser near U.S. 40 has been so ‘remodeled’ and is open to public inspection (and fishing). DW has committed millions to this work.

@DenverWater appeal of @BoulderCounty’s 1041 decision about the Moffat Collection System Project scheduled for March 14, 2019

From The Longmont Times-Call (Charlie Brennan):

Thursday looms as an important day for both proponents and opponents of an expansion at Gross Reservoir, as Boulder County commissioners meet to hear Denver Water officials make the case that the massive project should not be subject to the county review process.

Denver Water, which serves about 1.4 million customers in the Denver metro area, but none in Boulder County, had hoped to start construction this year on a project to raise the Gross Reservoir Dam in southwestern Boulder County by 131 feet to a height of 471 feet and expend the reservoir’s capacity by 77,000 acre-feet.

The project is subject of a federal lawsuit filed by a half-dozen environmental groups, and still must also obtain a licensing amendment at the Federal Energy Regulatory Commission in order to go forward.

Boulder County Land Use Director Dale Case on Oct. 22 issued a finding that Denver Water’s plans were subject to the county’s so-called “1041” review process, a decision Denver Water asked without success for Case to reconsider, before finally appealing the question to the commissioners.

Commissioners will hear Denver Water’s appeal starting 4:30 p.m. Thursday in a public hearing expected to last at least four hours. It will take place in the commissioners’ third-floor hearing room at 1325 Pearl St. in Boulder.

In-person sign-ups to speak will be taken beginning an hour in advance of the hearing, and commissioners are expected to issue a decision that night.

Moffat Collection System Project update: “I think their position is pretty clear” — Jim Lochhead #ColoradoRiver #COriver #aridification

Denver Water is seeking approvals from the U.S. Army Corps of Engineers, the U.S. Fish and Wildlife Service, and the state of Colorado to expand Gross Reservoir, which is southwest of Boulder. The 77,000 acre-foot expansion would help forestall shortages in Denver Water’s water system and offer flood and drought protection, according to Denver Water.

From The Sky-Hi News (Lance Maggart):

On Wednesday a collection of six environmental advocacy groups – Save the Colorado, the Environmental Group, Wildearth Guardians, Living Rivers, Waterkeeper Alliance Inc. and the Sierra Club – filed a lawsuit in Colorado’s federal district court against the proposed Gross Reservoir Expansion Project, alternately called the Moffat Firming Project…

The legal process surrounding Gross Reservoir has deep significance to Grand County. The county serves as the source for much of the water Denver Water relies upon, which is transported out of the county through the Moffat Tunnel near Winter Park Resort. The county is also party to a collaborative water management group called Learning By Doing. The group looks to improve river habitat in Grand County by conducting environmental water projects and through other means.

The lawsuit filed by the environmental groups does not name Denver Water and instead is directed at the US Army Corps of Engineers, the Department of the Interior and the US Fish and Wildlife Service. The 57-page complaint lays out 32 separate specific claims related to alleged violations of the National Environmental Policy Act, the Clean Water Act and the Endangered Species Act.

The alleged violations claimed by the environmental groups cover a wide range of technical issues related to the formal processes by which large construction projects, such as the Gross Reservoir Expansions, are approved by federal agencies. Many of the claims made by the environmental groups revolve around allegations that the Corps of Engineers, Interior Dept. and US Fish and Wildlife failed to exercise independent judgment related to claims made by Denver Water about the project.

“Denver Water’s proposal to build the largest dam in Colorado history will hurt the 40 million people in six states and two countries who depend on the Colorado River – a critical but disappearing, resource – for their water supply,” said Daniel E. Estrin, general counsel and advocacy director at Waterkeeper Alliance. “Waterkeeper Alliance stands united with our many Colorado River Basin Waterkeepers who are fighting to protect their waterways and their communities from this senseless and destructive water grab.”

For their part officials from Denver Water said the court filing did not surprise them.

“We expected it,” Jim Lochhead, CEO of Denver Water, said. “This is a really critical project for Denver Water. In the last 15 years we have come close to running out of water a couple of time at the north end of the system.”

Lochhead noted that those two incidents came in 2002 and 2013.

While Denver Water is not directly named in the lawsuit Lochhead said the organization will be entering the lawsuit to “provide our own perspective on the adequacy of the approvals.”

“We are confident the federal agencies follow regulations and federal law,” Lochhead said. “I think a court will uphold the findings by those agencies.”

When asked whether he believed Denver Water and the environmental groups who oppose the Gross Reservoir Expansion Project could reach some form of compromise agreement Lochhead answered, saying, “I think their position is pretty clear.”

“If I was to look at the one thing that changed the most in my public life, it’s the collaborative approach” — Gov. John Hickenlooper

Here’s an in-depth look at Gov. Hickenlooper’s legacy from Marianne Goodland writing for The Colorado Springs Gazette. Here’s an excerpt:

In a fast-growing state that places greater demands on its water supply each day, a state that regularly faces withering droughts, Hickenlooper has spent his eight years in office navigating water issues and leading the development of a state water plan that Denver’s chief water official calls a “real act of political courage.”

But not everyone believes the governor has made all the right choices on water. Colorado still faces daunting water-supply challenges. Some say Hickenlooper should have done more to promote dams and reservoirs and there’s no clear way to pay for the ambitious state water plan he fostered.

Still, many give Hickenlooper credit for reshaping how Colorado deals with water.

“He was the first governor to put water at the forefront,” said veteran northern Colorado water manager Eric Wilkinson.

Hickenlooper’s legacy may depend on what is done with the water plan that he is leaving for his successor. Colorado Politics talked to members of Colorado’s water community to see what they think his legacy in water looks like – and the governor weighed in on that, too.

US Drought Monitor June 25, 2002.

The beginnings

When Hickenlooper became mayor of Denver in July 2003, the state was already entering the second year of a record-setting drought. Gov. Bill Owens, in his 2003 State of the State address six months earlier, claimed the 2002 drought was the worst in 350 years, with most of Colorado in what the U.S. Drought Monitor called “exceptional drought,” the worst stage in their rankings.

So water got into the future governor’s mind early on, although as mayor, his control was limited primarily to appointing commissioners to Denver Water, the state’s largest water utility.

But as he saw it, he wasn’t dealing with just Denver’s water. It was water that belonged to the entire state, he said.

At the time, state officials were also trying to figure out how to solve the water problem. In the midst of devastating drought, the General Assembly and Owens began working on several ideas that still hold water today, including a new assessment of Colorado’s water supply, known as the Statewide Water Supply Initiative (SWSI)…

In the 2005 session, the General Assembly approved a law setting up groups known as basin roundtables, which divided Colorado into nine regions, each representing a major river, plus one for Denver.

But the groups weren’t required to work with each other. There were differences among the regions, including claims from the Western Slope that the Denver area was seeking more “transmountain diversions” to channel water from the Colorado River and other western waters through the mountains to the Front Range. That claim still sticks today.

And there were long-standing hard feelings over what happened about 15 years earlier, when ski towns joined forces with environmentalists to help defeat a major Denver reservoir project…

Two Forks was a proposed dam on the South Platte River that would have created a million acre-feet reservoir, flooding 30 miles of canyon from Deckers south to the river’s confluence with its north fork.

Advocates said the project was vital to supplying growing metro Denver. But environmentalists sounded the trumpets, complaining of the potential drowning of much of Cheesman Canyon with its prime fishing, hiking and kayaking areas, and the Environmental Protection Agency vetoed a permit for the project in 1990.

Denver Water, which exhausted its appeals of the rejection in 1996, was forced to shift to conservation rather than looking for major new water supplies from storage.

That’s the environment that Hickenlooper walked into as mayor. And that’s when his water legacy started, says Eric Kuhn, who has spent 40 years working on the Colorado River, including as general manager of the Colorado River Water Conservation District.

It was then, he said, that the groundwork was laid with Denver Water board members to build cooperation with Western Slope water providers.

Knowing that Denver Water controlled a quarter of the state’s water supply, it meant new conversations with the Western Slope water community. Those discussions started in 2006 between Denver Water and 42 Western Slope partners, ranging from water providers to local governments to ski resorts.

That eventually became the groundbreaking Colorado River Cooperative Agreement, first reached in 2011 and signed by all parties by 2013. The agreement resolved at least some of the historic fights over the Colorado River. It focused on efforts to improve the river’s health and looked for ways to provide additional water supplies to Denver Water…

Hickenlooper got one other big advantage during his time as mayor: The Denver Water board selected a new general manager, Jim Lochhead, who would continue the agenda set forth by the board and with Hickenlooper’s vision in hand. That took place in 2010.

Hickenlooper “made very thoughtful appointments” to the Denver Water board, including people like Tom Gougeon, John Lucero and George Beardsley, Lochhead told Colorado Politics. They were “really strong leaders with the ethics for moving Denver Water forward but with having us take a far-sighted approach with the Western Slope,” he said.

Part of a strategic plan

Hickenlooper says he tackled water issues again shortly after being elected governor in November 2010. The state found itself in another multi-year drought starting in 2011, and that’s when Hickenlooper asked if drought would be the new normal and how Colorado would deal with it.

He talked to other governors to research the best practices they employed, and found that what Colorado lacked was a comprehensive water plan, which he called a “serious vacuum” in the state’s framework. It was a risky proposition, given that Coloradans were historically polarized around the issue of water, he said.

There were things – like boosting water conservation – that he knew would be difficult. He knew rural Colorado’s farmers and ranchers did not want to be told what to do. “We couldn’t deny people the right to sell their property,” he said, referring to water rights. But the plan would look at how to incentivize farmers to at least temporarily lease their water rather than sell.

With the traditional east-west divide over water evolving with the completion of the Colorado River agreement, the time to strike came early on in Hickenlooper’s first term. He began asking his cabinet about a water plan.

According to James Eklund, who first served as Hickenlooper’s senior deputy legal counsel and then as director of the Colorado Water Conservation Board (CWCB), the governor was asked if he was willing to spend his political capital by wading into the water wars.

“Some governors only touch (the issue) on a superficial level,” Eklund told Colorado Politics. Previous governors would go to the Colorado Water Congress (the state’s leading water advocacy organization), pound the table, say that water is the lifeblood of the West and then get out.”

After the discussions with the other governors, that wasn’t going to be Hickenlooper’s way. “We have no choice but to treat this as a serious discussion” and to engage in strategic planning, according to Eklund.

Hickenlooper – a former restaurateur – looks at everything through a business lens, Eklund said. That meant that if water is so important to Colorado’s bottom line and there isn’t a strategic plan, that’s not acceptable.

In May 2013, Hickenlooper announced he would task Eklund and the CWCB to come up with a state water plan…

In November 2015, the water plan was unveiled after more than 30,000 public comments from all over the state. “We wanted to make sure all the interests were represented, not just conservation,” Hickenlooper said. “We also put in water storage,” meaning reservoirs, but that also ruffled the feathers of environmentalists, he said.

Hickenlooper said he was most pleased with the ability of the basin roundtables – set up in that 2005 legislation – to take the long view, especially for groups historically polarized over water.

According to many in the water community, it’s the statewide water plan that most defines Hickenlooper’s water legacy…

‘Water at the forefront’

The water plan attempts to address what is now expected to be a 1 million acre-feet shortage of water in Colorado by 2050, based in part on projected population growth of another 3 to 5 million people on top of the state’s current population of 5.6 million.

It focuses on a number of strategic goals: 400,000 acre-feet of water to be gained through conservation, another 400,000 to be gained through new or enhanced storage (dams and reservoirs), and the rest from other steps, such as agricultural water sharing.

The plan has its detractors who have criticized it for lack of specific objectives in how to achieve those goals. And some lawmakers believe the General Assembly has been shut out of the process and that storage gets short shrift.

Senate President Pro Tem Jerry Sonnenberg of Sterling told Colorado Politics that he’s been frustrated with the plan’s lack of attention to storage and that there hasn’t been enough emphasis on how to avoid “buy and dry” – the practice of buying up agricultural land for its water rights and then draining the land dry…

Sonnenberg disagrees that the water plan is a positive legacy for Hickenlooper.

“He tried to put the plan together and it didn’t get a lot of attention other than from the environmental community that wants to make sure we leave more water in the rivers. If you want to be a water leader with a water legacy, you must support water storage that is paid for by the communities planning for growth,” Sonnenberg said, citing the Northern Integrated Supply Project (NISP), which plans two reservoirs – Glade, near Fort Collins and Galeton, east of Greeley.

Sonnenberg complained that the governor has not yet endorsed those projects, although Hickenlooper did endorse two other reservoir projects two years ago: Chimney Hollow, near Loveland, and expansion of Gross Reservoir, near Boulder.

But Eric Wilkinson, who recently retired as general manager of Northern Water, which runs NISP, does believe in Hickenlooper’s water legacy.

“He was the first governor to put water at the forefront,” Wilkinson told Colorado Politics. He was pleased with Hickenlooper’s endorsement of Chimney Hollow, a Denver Water reservoir project, which he said tells federal agencies that the project has cleared Colorado’s permitting and is ready to go forward. That was part of the state water plan, too, Wilkinson noted.

ilkinson also pointed to the people Hickenlooper put in charge of water issues as part of the legacy: Stulp, Eklund and Becky Mitchell, the current head of the CWCB; and both of his heads of the Department of Natural Resources, first Mike King and now Bob Randall.

In the water plan, the balance between conservation and new storage is a pragmatic solution for the state’s future, Wilkinson said. “We need to have a greater ability to manage the water resources, and to do that, conservation is first, but infrastructure is very much needed. The water plan calls that out.”

The timing was right and the leadership was right, Stulp told Colorado Politics.

Hickenlooper saw what had been taking place for the past seven to eight years, after the formation of the basin roundtables, which came up with projects for their own regions. The time was right to pull all that together, Stulp said.

Eklund, now with the law firm Squire Patton Boggs, is still involved in water issues, partly as Colorado’s representative on the Upper Colorado River Commission. He said Hickenlooper’s legacy isn’t only about the water plan; it’s also where he positioned Colorado internationally on water issues.

Colorado’s position as a headwater state that provides water to 18 downstream states and Mexico means “we punch above our weight on water policy,” Eklund said. The eyes of the water-stressed world are on the Southwest United States.

Colorado finally has a platform in that discussion by coming up with the water plan, which he called a “gold standard” for water planning. Other states and nations can look at what Colorado is doing and judge for themselves, he said.

Colorado now speaks with one voice on water, said Mitchell, who was in charge of water planning prior to becoming the CWCB’s latest director.

“The default starting point now on water talk is cooperation, not confrontation,” she told Colorado Politics.

The water plan shows what’s possible, she added, when people with polarized perspectives and faulty assumptions sit down together, listen and speak with civility and respect…

Hickenlooper told Colorado Politics he hopes the next governor recognizes the funding gap for implementing the plan. The General Assembly has so far devoted about $17 million over the past two budget cycles to funding projects in the water plan, but it’s a drop in the bucket compared to the need, which is estimated at around $20 billion.

Water providers are expected to shoulder most of that, but the state’s obligation is expected to be around $3 billion, at $100 million per year for 30 years, starting in 2020.

No one, including Hickenlooper, has come up with a solid plan for where that money is coming from. Lots of ideas have been floated, such as changes to the state’s severance tax structure on oil and gas operations – a no-go with Senate Republicans – bottle taxes, water tap fees and the like.

Hickenlooper said he believes funding for the water plan is sufficient for the next few years, but there is a gap, and at some point, the state will need to spend more money on water infrastructure…

That political courage, and part of the legacy, as Lochhead sees it, is that Hickenlooper opened the door for the next governor to come in and pick up where Hickenlooper ended and made it a little safer for a governor to jump into water issues.

So how does Hickenlooper view his legacy in water?

“If I was to look at the one thing that changed the most in my public life, it’s the collaborative approach,” the governor said. “This is everyone’s issue.”

Projects underway to bridge #Colorado’s water supply gap

From Water Deeply (Matt Weiser):

At least seven major new reservoirs and water diversion projects are being planned in Colorado, which had a population of 5.6 million in 2017. Many would continue the controversial practice of diverting water across the Rocky Mountains from the state’s Western Slope, where the majority of Colorado’s precipitation falls, to its more arid Front Range, where people are flocking to Denver, Boulder, Fort Collins, Longmont and increasingly sprawling suburbs.

The water projects have been inspired partly by the Colorado Water Plan, an effort by Governor John Hickenlooper to solve a projected water deficit of 560,000 acre-feet by 2050, or enough to serve more than 1 million households. The plan calls for 400,000 acre-feet of new water storage and an equal amount of water conservation.

The plan is only two years old. But critics say it has prioritized gray infrastructure – new dams, pipelines and pumps – over green projects like water conservation and sustainable land use…

The state water plan does not recommend any specific water development projects. But Hickenlooper has personally endorsed several of them. He also appointed all the voting members of the Colorado Water Conservation Board, the entity that oversees the Water Plan and awards grants for water projects.

Greg Johnson, chief of water supply planning at the Water Conservation Board, said the state’s plan emphasizes conservation just as much as new water supply projects. But he said the latter may be more more pressing in some cases.

“Some of the bigger projects that are in permitting right now are helping meet really critical supply needs that a lot of those faster-growing northern Front Range suburbs have, where they’ve got new developments going up all over the place,” Johnson said. “They have maybe a 10- or 15-year horizon to get some of those things done.”

One of the water developments endorsed by the governor won a $90 million loan in 2017 from the Water Conservation Board – the largest loan in the board’s history. Known as the Windy Gap Firming Project, it proposes a new reservoir called the Chimney Hollow Reservoir near Longmont to store Colorado River water diverted through an existing tunnel under the Continental Divide.

The loan covers nearly one-fourth of total costs for the project, which is proposed by the Northern Colorado Water Conservancy District.

As its name implies, the project is intended to “firm up” existing Colorado River water rights held by a dozen Front Range cities. The cities already draw on these water rights, but can’t fully tap them in some years because of storage limitations. The new 90,000 acre-foot reservoir will solve this problem and allow them to divert the river almost every year.

The project would result in diverting 30,000 acre-feet more water out of the Colorado River every year than is currently diverted…

Other major projects in the works include the Moffat Collection System, a plan by Denver Water to expand Gross Reservoir to hold 77,000 acre-feet of additional diversions from Colorado River headwaters streams; and the White River Storage Project, a proposal for a new reservoir of up to 90,000 acre-feet in the northwest corner of the state, near the town of Rangely…

Greg Silkensen, a spokesman for the Northern Colorado Water Conservancy District, said the Windy Gap project is vital to many fast-growing Front Range communities that have lower-priority water rights.

“The Colorado economy is just crazy. Everybody and their brother is moving here,” Silkensen said. “There is a great deal of environmental mitigation that will go forward if the project is built. There’s going to be a lot of benefit to the Upper Colorado River if it does go through.”

Those projects include stream habitat restoration in the Colorado River and water quality improvements in Grand Lake, part of the existing Western Slope diversion system.

Steamboat “State of the River” meeting recap

From Steamboat Today (Tom Ross):

“The key with Lake Powell is that it is our river savings account,” Andy Mueller told a gathering of more than 200 people who packed into the Steamboat Springs Community Center Tuesday night for the Steamboat State of the River meeting, less than 50 feet from the banks of the Yampa River…

Less understood, Mueller said, is the Colorado River District’s stake in power generation at Glen Canyon Dam, where water levels are coming perilously close to dropping below the intakes for the power plant.

“It really starts with power generation at Lake Powell,” Mueller said. “That dam is a cash register for those of us on the river. It pays for the Colorado Endangered Fish Program, which allows all of us in Colorado to continue to divert water while the endangered fish are being protected.”

[…]

Mueller told his Steamboat audience that agricultural water rights continue to be of preeminent importance in the district.

“On the Western Slope, try to picture what it would look like without ag. It is a very different world if we don’t have irrigated agricultural land,” he said. “That’s where the water is. Eighty percent of the water consumed on the Western Slope is in ag. We have to protect this agriculture, and a lot of that has to do with agricultural water rights.”

[…]

The district represents about 28 percent of the physical land mass in Colorado but is home to just 500,000 of the 5 million people in the state. And 57 percent of the water produced statewide comes from the Colorado River District…

Lake Powell, backed up by Glen Canyon Dam, just above the Grand Canyon, is where the Rocky Mountain states, including Utah, Wyoming and the northern portions of Arizona and New Mexico store water to ensure they can meet their obligations to send water to the lower basins states including California, Nevada and southern New Mexico and Arizona.

As of 1999 the reservoir was almost full. But subsequent drought years, notably 2002, drew the reservoir down. It took until 2012 to slowly re-build storage in the vast reservoir, but snowpacks in the Colorado Basin have not been generous since.

As winters have grown milder, river flows are sapped and extended growing seasons are also resulting in plants absorbing more of the available water.

“We’re working on cloud seeding, but you have to have storm events in order to hit them with the silver iodide,” Mueller said.

“It isn’t the #drought draining #LakePowell as much as it is the overuse” — Andrew Mueller #ColoradoRiver #COriver

Colorado transmountain diversions via the State Engineer’s office

From The Montrose Press (Katharhynn Heidelberg):

Less water in the stream means less comes into large and critical impoundments such as Lake Powell, which Mueller said is already being “equalized” with Lake Mead. The latter is being drawn down by overuse, not just drought.

“They’ve been draining the savings account at Lake Mead for them (users), and, the way it works, they’ve also been draining Lake Powell,” Mueller said. “ … It isn’t the drought draining Lake Powell as much as it is the overuse and the lower supply of water going in.”

Colorado must be aware of that because of its requirements under the Colorado River Compact to deliver a set amount of water right below Glen Canyon Dam.

“There’s accounting that goes on. Every year, we know exactly how much water is delivered. At a point in time … we can see very clearly, we have a significant risk of not being able to deliver that water,” Mueller said. “When we can’t deliver that water, we will get a call, or a curtailment, coming up the river.”

He said it appeared as though most of those present Jan. 19 have pre-compact water, or senior rights, that are not obligated to be called out. Most municipalities have rights junior to the compact — but they also have the right of condemnation through an involuntarily “buy and dry” process.

“Those (municipal) fire hydrants and those faucets, my guess is, are going to get water in the time of curtailment. That’s the municipal preference in our state constitution,” Mueller said.

To-date, the state hasn’t actually had to determine how this consideration would be applied — in fact, mum’s the word at the state level, Mueller added.

“The reality is, many of the Front Range providers would have rights junior to the compact,” Mueller said. These providers divert about 650,000 acre-feet a year to the Front Range out of the Colorado River Basin, including, at times, the Upper Gunnison.

The Front Range is constantly on the lookout for additional supply, but that’s not the only thing to keep in mind, Mueller said. Front Range providers will continue to supply current municipal needs in that populous part of the state.

The question becomes: What happens in the event of a curtailment when municipalities have the right of condemnation?

“They have the right to come over and buy ag rights. They don’t even have to build a pump. They can just run the water down the stream into Lake Powell. They can dry up the agricultural — buy and dry involuntarily,” Mueller said.

Locals under the Uncompahgre Valley Water Users Association are not necessarily safe from condemnation just because the association is under a right held by the federal government, he said.

Although municipalities cannot condemn against federal property, it’s not certain whether the U.S. Secretary of the Interior would ultimately be comfortable with not delivering water to the lower basin, where the greater population provides a congressional delegation many times the size of the Western Slope’s, Mueller explained.

“The question really is, how do we prevent that from happening?” he said.

“We don’t have the answer yet, but we are studying a number of different mechanisms where we can use voluntary efforts by our agricultural producers on the Western Slope, combined with voluntary efforts of ag users who depend on transmountain diversions on the Eastern Slope; industrial providers on the East Slope, and municipal providers on the East and West Slope, to voluntarily curtail their uses ahead of time and bank that water somewhere and then be able to prevent a curtailment from ever occurring.”

These, Mueller explained, are “thoughts,” not absolutes.

Moffat Collection System Project will impact forest surrounding existing Gross Reservoir

From The Boulder Daily Camera (Charlie Brennan):

The Federal Energy Regulatory Commission is expected to rule early next year on what would be the biggest public works project in Boulder County history, exceeding the original construction of the Gross Reservoir Dam, which was completed in 1954.

The tree removal plan outlined in Denver Water’s FERC application states that all trees and their associated debris on about 430 acres along 12.5 miles of shoreline will have to be removed in the course of the expansion, which is envisioned as being completed by 2025.

Denver Water spokeswoman Stacy Chesney said the agency has estimated that “the density of the forest ranges from approximately 150 to 1,800 trees per acre. Based on these initial plans, we estimate up to 650,000 trees will need to be removed in the area surrounding Gross Reservoir.”

In a recent interview, Denver Water President Jim Lochhead vowed that every aspect of the project’s completion is being designed and executed with an eye toward mitigation of its impacts on the high country environment and those who depend on it for their recreation or call it home.

“We recognize that this is a major construction project and it has adverse impacts to the community,” said Lochhead, whose utility serves 1.4 million in Denver and many of its suburbs — but not Boulder County.

“We are trying to understand exactly what those impacts are, and see what the needs of the community are, and do everything we can to help address them.”

Referencing project manager Jeff Martin, Lochhead said, “Whether it’s traffic, hauling on the roads, whether it’s noise associated with the quarry, whether it’s the tree removal issues, it’s Jeff’s job to make sure it goes in a way that we’re doing the best that we can by the local community.”

Martin said: “We recognize the brutal aspects of the project. We don’t want to hide from those. That’s not our objective.”

Stressing that Denver Water intends to factor the concerns of reservoir neighbors into its planning of what’s officially known as the Moffat Collection System Project, Martin said, “We look forward to getting that feedback, seeing how we can make it into the most palatable project we can, and turn it into, maybe not reducing all the impacts, but for the greater good, reducing them as much as we can.”

[…]

A 48-page plan for the required tree removal prepared by Denver Water describes a mix of ponderosa pine, Douglas fir and Rocky Mountain juniper.

According to data the agency compiled in 2005, most of the trees at that time were 20 to 50 feet high, with a breast-high diameter ranging from 4 to 14 inches.

“Because of the topography, e.g., very steep slopes, rock outcrops, etc., several more complex tree removal (logging) systems will need to be used, and some temporary roads will need to be constructed to remove the trees,” the plan states.

It estimates that 50,000 tons of forest biomass are expected to be produced during the required clearing for the expansion of Gross Reservoir, which is to see its dam raised by 131 feet, expanding the reservoir’s capacity by 77,000 acre feet to a total storage capacity of 118,811 acre feet.

While noting that, “Traditionally, most of the slash would have been piled and burned in place,” the plan acknowledges that, “Today, burning large quantities of forest residue, in close proximity to residential areas, is problematic in the extreme.”

Allen Owen, Boulder District forester for the Colorado State Forest Service — a contracted forest resource management partner to Denver Water through the Forests to Faucets program — said he had been unaware of the number of trees Denver Water is planning to pull out of the Gross Reservoir area, or that it will involve the leveling of all growth on 430 acres of shoreline.

He doubts it would actually reach the 650,000 figure.

“That would mean 1,500 trees per acre over the entire 430-acre unit, and I know that’s not the case,” he said. “The stand densities vary all around the perimeter of the shoreline. There are areas that are nothing but solid rock, with no vegetation on it, to units that may have those number of trees. But there are not that many trees over the entire 430 acres. The number seems high.”

Owen expects state foresters will be involved in plotting how the trees’ removal proceeds.

“It’s something way beyond the ability of the Colorado State Forest Service,” he said. “I would consider that a big logging job, on very steep slopes, with very poor access. It is going to be very difficult, at best.”

Martin discussed three different potential scenarios, including removal by truck, burning and burial of felled lumber, or some combination of those strategies.

In cases where trees are located on small rock bluffs, Denver Water’s current removal plan notes, “the use of helicopter may be necessary.”

Denver Water believes new emerging technologies may pose options for removal that weren’t contemplated when its plan was authored.

“One of the things we’ve committed to is developing a process with public input … going out and getting some public input and some stakeholder input and that includes the U.S. Forest Service, the Colorado state forester and Boulder County, and developing some concepts … and then seeing what fits best for the community from there, and then moving forward with the plan,” Martin said…

Denver Water points to steps it is taking to mitigate the effects of construction wherever possible, and also emphasizes measures that it contends offers some in Boulder County a benefit. Lochhead and Martin touted the provision of a 5,000-square-foot environmental pool in the expanded reservoir, to be available for replenishing South Boulder Creek for the benefit of both Boulder and Lafayette at times when it is running dangerously low.

“That’s kind of a neat partnership there,” Lochhead said.

That does not mean that Boulder supports the Gross Reservoir expansion — but nor does it oppose it.

“Boulder has a neutral position on the overall expansion,” said Boulder’s source water administrator, Joanna Bloom.

“If the project somehow falls apart, then Boulder will continue to try to establish the streamflows on South Boulder Creek through other means,” Bloom said…

Boulder County’s stance on the expansion is more complicated.

The county filed extensive comments on both the draft and final environmental impact statements in the Army Corps of Engineers’ review process, and doesn’t agree that the EIS adequately addressed “the myriad of impacts” that would result for Boulder County and its citizens.

On March 23, the county filed an unopposed motion to intervene in the FERC approval process. One of the points the county addressed at length in that intervention relates to tree removal — and its arguments are based on the presumption of a far more modest, but still significant, removal of trees, at a total of 200,000.

“County roads (Flagstaff Road, Magnolia Road and others) are windy with low volume residential traffic and would be inappropriate for use by trucks hauling trees,” the county argued.

“In addition, it may not be possible to safely navigate SH 72 with trucks full of trees. These heavily laden trucks will cause damage to the roads and present safety concerns for road users.”

Moreover, the county contends Denver Water’s project must come through its land use review process, while the utility maintains that the county’s role is superseded by the FERC review process.

Until that conflict is resolved, the county is tempering its remarks, pro or con, on the Gross Reservoir project, so that it will not be seen as having prejudged any application Denver Water might make in the future through the county’s land review process.

Martin recalled that Denver Water worked extensively with Boulder County in 2012 exploring a potential intergovernmental agreement to facilitate the reservoir expansion.

While such a pact was ultimately rejected by Boulder County commissioners by a 3-0 vote, Martin said, “What we did receive was a lot of information from Boulder County and the public on how we need to shape the project in order to meet the needs of both the community and Boulder County.”

However, independent of the environmentalists’ planned federal lawsuit, there might be a need for another judge to sort out the critical question of whether Denver Water’s plans for tree removal and many other aspects of its reservoir expansion must pass through the county’s land use review process.

“I would say that it is likely that it will take litigation, because neither party is willing to give up its position,” said Conrad Lattes, assistant county attorney for Boulder County. “We need some neutral third party to decide this for us.”

However, on a warm and sunny day back before the chill of approaching winter descended on Colorado’s high country, Denver Water’s brass were flush with optimism.

Martin said that for Denver Water, it’s not just about getting the project done.

“We’re also looking at the social responsibility,” he said, “making sure that when it’s said and done, that we did it in the right way; that we could look back and say we did everything within reason and practicality to make this really the most environmentally, socially responsible project we can.”

State gives Aspen officials until Dec. 29 to answer dam questions

The location of the potential Maroon Creek Reservoir, just below the confluence of East and West Maroon creeks, where a beaver dam now backs up water. The Maroon Bells are well within view from the dam site.

By Brent Gardner-Smith, Aspen Journalism

The city of Aspen now has until Dec. 29 to provide a “substantive” response to central questions raised by state officials in water court regarding the city’s efforts to develop dams and reservoirs on upper Maroon and Castle creeks.

The questions raised by the state include whether the city can get a permit for the dams, if it can build the dams in reasonable time, if it has a specific plan to build them, and if it needs the water the reservoirs would hold.

After a status conference on Nov. 9 in water court in Glenwood Springs regarding two due diligence applications the city filed in December 2016 for the two potential dam-and-reservoir projects, a water court referee said, for the second time since August, that the city must provide a substantive response to key issues raised by the state.

Susan Ryan, the referee in Division 5 water court, said the city must do so whether or not it is able to reach settlement agreements with the 10 opposing parties in the two cases.

“It is going to require a written response to that summary of consultation regardless of whether or not settlement is reached with all the opposers in the case,” Ryan said during the status conference. “And so I just wanted to clarify that that is what I typically require in every water case and that is what I will require here.”

A summary of consultation in water court can be a routine review of a water rights application by two state officials, the division engineer, who administers water rights, and the water court referee, who functions as an administrative judge and seeks to resolve cases, if possible, before they are sent to a water court judge.

But the twin summaries of consultation released on Jan. 23 concerning the city’s diligence applications for the Castle and Maroon creek reservoirs raised threshold questions.

They said the city “must demonstrate that it will secure permits and land-use approvals that are necessary to apply the subject water rights to beneficial use” and the city must show it “will complete the appropriations within a reasonable time.”

They also said “a specific plan is in place to develop the subject water rights,” that the city “must demonstrate substantiated population growth in order to justify the continued need for these water rights” and that the city is “not speculating with the subject water rights.”

Maroon Creek Reservoir would hold 4,567 acre-feet of water behind a 155-foot-tall dam and encroach on portions of the Maroon Bells-Snowmass Wilderness. Castle Creek Reservoir, as currently decreed, would hold 9,062 acre-feet of water behind a 170-foot-tall dam, and would also flood some land in the wilderness boundary.

In two diligence applications filed on Oct. 31, 2016, the city told the court it has “steadily applied effort to complete the appropriation” of the conditional water rights for both of the reservoirs over the past six years, and that it has done so “in a reasonably expedient and efficient manner under all the facts and circumstances.”

In July, the city said it was seeking a way to transfer decreed storage rights to locations other than the decreed locations on Castle Creek and Maroon Creek.

On Nov. 7, city of Aspen voters rejected a ballot question that would have given the city the go-ahead to issue $5.5 million in general obligation bonds to purchase a 60-acre parcel in Woody Creek to use for water storage, in conjunction with the gravel pit operated by Elam Construction.

But city officials, before the vote, had stated they intended to buy the Woody Creek parcel whether the ballot question was approved or not. A recent study for the city found that between 1,000 acre-feet and 8,000 acre-feet of water could be stored using varying combinations of the land the city intends to buy and the gravel pit.

Also in July, the city filed brief responses to the summaries of consultation. But in August the water court referee said the city’s effort fell short.

A wetland that would be flooded under the potential Castle Creek Reservoir. The reservoir would stand across the main channel of Castle Creek, about two miles below Ashcroft.

City not eager to file response

During the Nov. 9 status conference, the city’s water attorney, Cynthia Covell of Alperstein and Covell, told Ryan the city would still prefer not to lay out its case in a substantive response at this stage of the proceedings.

“Since the last status conference the city has been working to finalize the reports that it has needed to assist in the settlement process, including its supply-and- demand risk assessment study, and its evaluation of one or more alternative storage sites that are not located in federal wilderness areas or on Castle Creek or Maroon Creek,” Covell said.

Covell said the city has only this week received responses from all 10 of the opposing parties to a Sept. 20 settlement proposal from the city, and that the City Council was scheduled meet in executive session Monday to discuss the responses.

“So at this point, Aspen would like to devote its time and resources to seeing if we can reach a settlement by the end of the year, we hope in both cases,” Covell said.

Attorneys in the cases said in August the main sticking point in the settlement negotiations was that the city wanted to keep open its options regarding transferring rights tied to the potential Castle Creek reservoir, while opposing parties want the rights for the potential reservoirs fully removed from both valleys.

During the status conference, after determining it was still the city’s position that it would prefer not to provide substantive answers at this time, Ryan asked the opposing attorneys what they thought.

“I frankly don’t buy the argument that it’s a hiccup or roadblock in terms of settlement,” attorney Paul Noto said. “I actually feel that it may lay some cards on the table that may in fact help settlement.”

Noto is representing American Rivers, Colorado Trout Unlimited, and the Roaring Fork Land and Cattle Co. in the Maroon Creek case, and the two environmental groups in the Castle Creek case.

Also opposing the city in the cases are Western Resource Advocates, Wilderness Workshop, Pitkin County, USFS, Larsen Family Limited Partnership in the Maroon Creek case, and Double R Creek Ltd. and Asp Properties LLC in the Castle Creek case.

Water managers seek certainty in Colorado Basin — @AspenJournalism

The Colorado River, not far below the Utah-Colorado state line, flowing toward the lower basin.

GRAND JUNCTION — Bringing more certainty to an unruly and unpredictable Colorado River system was a common theme among water managers speaking at the Colorado River District’s annual seminar Friday­­.

Although the drought that has gripped much of the Colorado River Basin for the past 16 years has eased up a bit, population growth and the long dry spell have pushed the river’s supplies to the limit, with every drop of water in the system now accounted for.

Meanwhile, the effects of climate change on the Colorado’s future flows are still a big question mark, and it could mean wide variability in the years to come, with periods of punishing drought followed by a sudden record-setting wet year, as California recently experienced.

Bill Hasencamp, general manager of Colorado River resources for the Metropolitan Water District of Southern California, described how in April 2015, snowpack in the Sierras was at an all-time low. But by this spring, it was at an all-time high, after a winter of heavy precipitation.

The change in snowpack eventually led to huge fluctuations in water prices – from $1,800 per acre-foot at the height of the drought to just $18 per acre-foot this year, Hasencamp said.

That kind of turbulence places enormous pressure on the Colorado River Basin’s big municipalities, which must secure their water supplies for millions of people, said Eric Kuhn, the general manager of the River District, which is based in Glenwood Springs and helps protect western Colorado’s water resources.

Kuhn is retiring next year and was making his last formal presentation as general manager of the river district. As he heads into retirement, he’s working on a book with author John Fleck about the history of managing the Colorado River and the creation of the Colorado Compact.

“The reality is — and we all have to accept this — big-city providers need certainty,” he said. However, Kuhn said he didn’t think that means more transmountain diversions from the Western Slope.

The most obvious source of additional water for cities is agriculture, which holds the lion’s share of senior water rights on the Colorado River, but no one is eager to see rural areas sacrificed for urban growth, Kuhn said.

So, he added, water managers throughout the basin are figuring out ways to adapt 19th-century water laws to a 21st-century reality.

The upper Colorado River below the Pumphouse put-in.

System conservation

Cooperative agreements between irrigators and municipalities are one option, providing cities with additional sources of water during dry periods.

Already, a three-year pilot initiative called the System Conservation Pilot Program has shown that farmers and ranchers are open to using less water in exchange for compensation.

Beginning in 2014, four of the big Colorado River Basin municipalities and the Bureau of Reclamation contributed $15 million to fund water conservation projects throughout the basin.

The program was in limbo after this year while officials worked out some issues, but Hasencamp said Friday that the funders have agreed to continue the pilot program for another year, in 2018.

For water managers, these kinds of flexible arrangements, along with rigorous water efficiency, recycling, and reuse efforts, are the key to finding “certainty” on an inherently volatile river system.

Still, those solutions will not be easy.

As Bill Trampe, a longtime rancher from Gunnison County, explained, less irrigation often comes with unintended consequences such as diminished return flows to the river and nearby fields.

And as Lurline Underbrink Curran, the former county manager for Grand County, described, efforts to heal the destructive impacts of existing water diversions on the Fraser River, a tributary of the Colorado, means accepting that future diversions will in fact take place.

“We tried to form friendships that would help us do more with what we had,” she said.

California’s Salton Sea presents another dilemma, which reaches back up into Colorado River system.

The salty inland lake, created by an accidental breach in an irrigation canal, is drying up.

Since 2002, the state of California has been paying the Imperial Valley Irrigation District to keep the Salton Sea on life support by delivering 800,000 acre-feet of water, but that initiative expires at the end of this year.

Continuing the water deliveries means using up more of the Colorado River’s dwindling supplies, but letting it dry up means exposing local residents to a lakebed full of toxic dust.

None of these problems is new, but as many of the speakers at the river district’s annual seminar explained, water managers now have more tools than ever before to address those challenges — and new urgency with which to apply them.

Recent successes include the successful negotiation of an updated binational water agreement between the U.S. and Mexico, called Minute 232, that is expected to be signed this month. It will outline how the two countries share future shortages on the Colorado River.

“We’re at a point where we can work together, and the success we’ve had is from collaboration,” said Becky Mitchell, the new director of the Colorado River Conservation Board. “It’s really all hands on deck.”

Interview: Jim Lochhead #ColoradoRiver #COriver

Jim Lochhead

Here’s an interview with Jim Lochhead from Cathy Proctor and The Denver Business Journal. Click through and read the whole thing. Here’s an excerpt:

As metro Denver grows, what’s the outlook for its water supply? We went to the source to ask.

Denver Water is the state’s biggest water utility, ensuring that 1.4 million customers in Denver and many surrounding suburbs have enough clean water for drinking, showering, cooking and yard watering.

Jim Lochhead was appointed its CEO and manager in 2010, after working for decades as a lawyer negotiating water rights and uses across the nation.

He sat down with me to talk about Denver’s water future. Here are some highlights.

What challenges lie ahead?

We’re doing an integrated resource plan, a 50-year look ahead to the challenges we face and how we face them — but it’s scenario planning, rather than math. Before, we looked at the past and how much water was available, figured how many people there would be in the future and did the math. But saying “we just need to get more water” doesn’t work anymore. The future will not look like the past for a number of reasons.

On the supply side, there may be more extended droughts, greater severity of weather events, and a warming climate. For demand, we’ve seen demand dropping due to our campaign for water conservation, but it’s also through more efficient fixtures and more density in the city — which means more efficiency.

Economics plans a part to, we could have economic downturns or just chug along, or the millennials moving into the downtown apartments might move to the suburbs. We’re creating different scenarios for all that.

Army Corps of Engineers approves Gross Dam expansion — @DenverWater

The Gross Reservoir Expansion Project will add 77,000 total acre feet — 72,000 for Denver Water use and 5,000 for an environmental pool that provides additional water for South Boulder Creek during low-flow periods — nearly tripling reservoir capacity.

Here’s the release from Denver Water (Stacy Chesney):

Army Corps of Engineers issues record of decision and 404 Permit

Following 14 years of careful study, evaluation and deliberation, the Army Corps of Engineers has approved Denver Water’s request to raise Gross Dam in Boulder County. The additional water stored in Gross Reservoir will help prevent future shortfalls during droughts and helps offset an imbalance in Denver Water’s collection system.

The approval comes in the form of a record of decision and 404 Permit — two documents required by the federal government as part of the National Environmental Policy Act.

“Denver Water appreciates the Corps’ dedication and commitment to careful study of the anticipated impacts of this project,” said Denver Water CEO Jim Lochhead. “We will complete this project responsibly, as evidenced by our actions during the public process and the resulting robust environmental protections we’ve agreed to along the way. We’re proud to be doing the right thing.”

The existing dam was built in the early 1950s and was designed to be expanded in the future to increase water storage capacity. The Gross Reservoir Expansion Project approval completes this original vision.

Expanding Gross Reservoir is a major part of Denver Water’s long-term plan to deliver safe, reliable water to the people it serves now and into the future. The project is part of Denver Water’s multi-pronged approach that includes conservation, reuse and responsibly sourcing new supply.

“Issuance of this permit will unlock significant resources that will allow us to do good things for the river and the environment,” said Mely Whiting, counsel for Trout Unlimited.

In accordance with existing agreements, including the Colorado River Cooperative Agreement and Grand County’s Learning By Doing, and conditions in the 404 Permit, Denver Water will provide millions of dollars to improve watershed health in the critical Colorado and South Platte River Basins. Lochhead said these commitments are one reason that last year Colorado Department of Public Health and Environment found that the project will have a “net environmental benefit” on the state.

The project has earned key endorsements from Gov. Hickenlooper, state and federal lawmakers, major environmental groups, local mayors and city councils, chambers of commerce and economic development corporations, county elected officials and water interests on both sides of the divide.

“The next milestone we anticipate is approval by the Federal Energy Regulatory Commission of Denver Water’s hydropower license amendment application at some point next year,” said Jeff Martin, Gross Reservoir Expansion program manager. “In the meantime, Denver Water continues to make significant investments in setting a firm foundation for the project’s overall success by recently hiring Black and Veatch as the owner’s representative. We are also in the process of procuring a design engineer.”

Preconstruction activities, including dam design and geotechnical work, are expected to begin in 2018. The entire project is expected to be completed in 2025.

From The Associated Press via The U.S. News & World Report:

The Army Corps of Engineers announced late Friday it granted the project a permit under the federal Clean Water Act.

The $380 million project involves Gross Dam in the foothills about 5 miles southwest of Boulder.

Water Education Colorado 2017 President’s Award Reception

The Denver Art Museum was the location for The Colorado Foundation for Water Education’s President’s Award Reception yesterday evening.

Eric Kuhn received the Dianne Hoppe Leadership Award and Drew Beckwith was honored as an Emerging Leader.

Each year when I attend this event I am struck by the camaraderie shown by the water folks here in Colorado. Water really does bring us together to find solutions, and at the end of the day we have so much to agree on. Water for Ag, water to drive the economy, water for the fish and bugs. It takes a great number of people to meet the water needs of the Headwaters State, collaboration is key, and this event helps us to connect.

Jim Lochhead introduced Eric Kuhn and detailed his accomplishments while leading the Colorado River District. The Colorado River Cooperative Agreement and the Windy Gap Firming agreement were at the top of the list. Lochhead also praised Mr. Kuhn as one of the two most influential persons in the Colorado River Basin along with Pat Mulroy.

Drew Beckwith

Eric Hecox told us about Drew Beckwith’s influence on the Statewide Water Supply Initiative. Eric credited Mr. Beckwith for poring over the workbooks, questioning assumptions, and advocating for conservation.

Drew is an accomplished water educator himself choosing video in the Drew in a Canoe series. He helped get the public on board with legislation passed in 2016 to legalize rain barrels.

People that install rain barrels are, “More connected to water,” he said.

This is always a great event to attend. Thanks Jayla, Caitlin, Jenny, and Stephanie.

“We’re kind of at the cliff right now in the Colorado River Basin” — Matt Rice

From Colorado Public Radio (Nathaniel Minor):

Colorado’s economy depends on water: where it is, where the people who need it live and work, who has rights to it. Fights over those needs are a core part of the state’s history, and they tend to follow a pattern. So in some ways, the fight over the Fraser River in Colorado’s Grand County is familiar.

Denver Water holds unused water rights on the river, which starts in the shadow of Berthoud Pass and courses down the western side of the Continental Divide past Winter Park, Fraser and Tabernash to join the Colorado River outside of Granby.

Workers pose for a photo in the Moffat Water Tunnel in this 1930 photo.
Workers pose for a photo in the Moffat Water Tunnel in this 1930 photo.

The agency, looking at the booming population and economy in Denver, now wants to exercise those rights. That means taking more water from the river, piping it under the Indian Peaks and sending it into Gross Reservoir near Boulder.

Some conservationists and environmental groups are crying foul, saying that the river has already been overtaxed (about 60 percent of its existing flow is already diverted to slake Denver’s growing thirst) and it’s time to let the river alone.

But the fight’s pattern is taking some unfamiliar twists and turns. Influential groups like Trout Unlimited and American Rivers, who’ve historically fought diversion projects, support this one. In exchange, Denver Water says it will will help protect and enhance what’s left of the Fraser River.

That compromise has fractured traditional lines in Colorado’s conservation and environmental advocacy community, and fostered new alliances. While these organizations more or less agree on their ultimate goal — to protect and restore the environment — the strategies they use are very different. The big question that divides them: When to compromise?

Denver Water Extends An Olive Branch

stoptwoforksdampostcardfrontcirca1988

Decades ago, environmentalists were not at the top of list of Denver Water’s concerns when it would try to build dams and add capacity. In the 1980s, environmental groups pushed back on a huge proposed dam called Two Forks.

“[Denver Water] told us in so many words: ‘We’re the experts. You’re little environmentalists. Get out of the way,’ ” Dan Luecke, then head of Environmental Defense Fund’s Rocky Mountain office, told High Country News in 2000.

Then, in 1990, an EPA veto torpedoed the project at the last minute.

“That was really a turning point for our organization,” said Kevin Urie, a scientist who’s worked for Denver Water for nearly 30 years. “I think we realized with the veto of Two Forks that we needed to think about things differently.”

He believes that while Denver Water has long taken environmental impacts into consideration with its plans, it didn’t engage with local stakeholders — like conservation and environmental groups and Western Slope governments — until after the Two Forks project died.

There’s a demographic change underway as well: Many of the Denver metro area’s new residents also want to play in Western Slope rivers on the weekends. That has pushed Denver Water leadership to put a larger emphasis on environmental stewardship, Urie said.

But all those new residents still need water. Denver Water delivers water to about 1.4 million people across the metro, about double what it did some 60 years ago. Conservation efforts have kept overall demand relatively low in recent years. But with more people moving to Denver every day, Denver Water expects its demand to rise 37 percent by 2032 from 2002 levels.

The Fraser River is key to Denver Water’s plan to head off a shortfall in the relatively near future. The agency wants to divert half of the remaining flows from the Fraser and its tributaries through the Moffat Tunnel to Gross Reservoir near Boulder. (The proposed expansion of Gross has started its own fight, which CPR News’ Grace Hood chronicled last month.) It would be treated at the agency’s plant in Lakewood, and eventually delivered to customers across the metro.

The agency expects to have all of its necessary permits by 2018 and construction could begin in 2019 or 2020. But to get those permits, Denver Water has agreed to be part of a group that includes Grand County officials and environmentalists called “Learning by Doing.” These different players are often at odds when it comes to water issues.

Urie said Denver Water’s participation shows its desire to do right by the environment and local stakeholders. They’ve helped fund an ambitious project that will engineer the Fraser River’s flow on a nearly mile-long stretch between Fraser and Tabernash, squeezing it to make it narrower, deeper and colder — and thus healthier.

But is that what’s best for the river?

Urie thought about that question for a minute, and then chose his words carefully:

“Clearly the system would be better if we weren’t using the water resources for other uses. But that’s not the scenario we are dealing with,” Urie said.

Trout Unlimited Sees Opportunity

The Fraser River project’s biggest booster is Kirk Klancke, president of the Colorado River Headwaters Chapter of Trout Unlimited. For him personally, it’s a way to help a river that he’s lived near and played in for 45 years.
“I can’t talk about it without getting all emotional. My life’s been spent on this river,” he said.

He sees it as a chance to restore a part of the river popular with anglers called the Fraser Flats. Here, the brush-lined river levels out after tumbling through the pine forests of Berthoud Pass.

His playground is popular with others, too. Grand County is a short one- to two-hour drive from Denver. From fly fishing to alpine and nordic skiing to snowmobiling, it’s a tourist-based economy. And in Klancke’s eyes, all of that rests on the health of its water.

He’s watched the river dwindle and get warmer as more water has been pulled out of it. And that’s changed how his family has used it. When his children were young, they could stay in the river for only a minute or two.

“They’d come out and their lips would be purple and they’d be squealing,” Klancke said. “Now I throw my grandchildren in the river and they’re not in a hurry to get out. We spend up to an hour in a pool in the river.”

He’s watched this river that means so much to him get sicker and sicker; warm, shallow channels aren’t suitable for native fish and bugs. For years, he blamed the deteriorating environment on the Front Range and its water managers.

“I was a little radical because I urinated in diversion ditches. It’s about all I knew to do. I’ve matured quite a bit since then,” he said.

His turning point came when he got involved with Trout Unlimited.

“I loved their approach,” he said. “They were able to look at it in someone else’s shoes, which is what all mature people do. And then, move forward with opening up conversation.”

Such conversations are what led to the Fraser Flats project, Klancke said. When flows are low, like they were this fall, the river is shallow as it stretches across its native bed. The new channel will allow the river to recede and stay deeper — and cooler.

Essentially, that stretch of river will be turned into a creek. On its face, downsizing a river doesn’t sound like a big victory for environmentalists. But that’s not how Klancke looks at it. During peak flows in the spring, Klancke points out, the river will be nearly just as wild as it is now.

And moreover, Denver Water has to stay involved in the Learning by Doing group. So if environmental issues arise down the road, Klancke said the agency will be there to help solve them.

Is it a compromise? Yes, Klancke admits. But water managers own water rights in the upper Colorado Basin that they’ll use — with or without his blessing. The right to divert water for “beneficial uses” is enshrined in the Colorado Constitution.

“We have to face reality here,” Klancke said. “There is no more mighty Upper Colorado. There’s only keeping what’s left healthy.” [ed. emphasis mine]

WildEarth Guardians Stakes Out Moral High Ground

Like Klancke, Jen Pelz, wild river program director for WildEarth Guardians, has had her own evolution in thought toward environmental causes. Earlier in her career, she was a water lawyer in Denver who represented clients like the city of Pueblo that were taking water from Western Slope rivers.

But eventually she felt a pull toward environmental advocacy. Pelz credits that with childhood days spent on the banks of a tributary to the Rio Grande in New Mexico.

“It was kind of the place that I could go just be myself,” she said. “I developed a really strong connection to the river there.”

She was drawn to the confrontational, no-holds-barred approach used by WildEarth Guardians. The group is known for its headline-grabbing lawsuits. Most recently they sued the federal government over haze in Western Colorado and leases to coal mines.

The approach seems to be working, at least by WildEarth Guardian’s measure. The haze lawsuit ended in an agreement where a coal mine and coal-fired power plant in Nucla, south of Grand Junction, will shut down in the next six years. A power plant in Craig, Colorado will shut down one of its units too.

“We’re willing to not be liked by the general public, or by particular industries,” Pelz said. “And I think it takes that kind of moral integrity and just knowing where you stand on the issues, to really push the envelope.” [ed. emphasis mine]

Pelz is not interested in compromise on the Fraser River. She faults Trout Unlimited for starting negotiations at the wrong place. In her view, the baseline shouldn’t be where the river is now with about 60 percent of it being diverted. The conversation needs to start with the river at its natural flows, she said.

“The harm has already been done,” Pelz said.

If the Fraser River is going to be saved, she says, it’ll happen by letting more water back into the river — not by taking more out. As the climate warms, she says the river will need all the help it can get.

“Let’s start dealing with it now. Let’s have that hard conversation now, not 50 years from now when there’s no water left to have a conversation about,” she says.

Pelz says her organization, and another group called Save the Colorado, are considering litigation once final permits are approved. That could happen in 2018.

Such tactics doesn’t make Pelz a lot of friends. She said she’s been ostracized from her former clique of water lawyers. It’s hard for her to get meetings with government regulators.

WildEarth Guardians’ relationship with the greater environmental community is similarly strained. She said Denver Water is more willing to meet with environmentalists now because they’ve softened. And she’s upset with what Trout Unlimited has become in the eyes of regulators.

“Trout Unlimited has been deemed by Denver Water and the state of Colorado as being the environmental voice,” Pelz said. “They get invited to the table because they have this role in communities, which I don’t think is a bad thing, but they don’t necessarily represent all of the different interests in the environmental community.”

As a result, she said, groups like hers are being left out of the conversation.

“They don’t talk to us. They don’t ask us what we think. And I’ve called them. And I’ve had meetings with them. I’ve asked them what they think. And they’ve told me they don’t like our approach. And I understand that. But I think that it works both ways.”

Pelz said it can be hard to be out “towing the left line.” Everybody likes to be liked, she said. But she’s decided that over the long run, her methods are what will make a difference. To do anything else would be surrender.

“I don’t want to have to explain to my kids that I gave up the fight for this river that is the namesake of our state, the state they were born in, because I was willing to compromise,” she said. “We may not win, but damn we are going to try.”

American Rivers Finds Room To Maneuver

When Matt Rice, Colorado River basin director for American Rivers took the job a few years ago, he made the decision to put aside his dreams for what he really wanted. Instead, he focuses on what he thinks he can actually pull off.

“In a perfect world, I’d like to see all the wild rivers in this country and in this state flowing freely and filled with fish, doing what rivers should do,” Rice said. “It’s not realistic.”

But he acknowledges that groups like WildEarth Guardians can make his job easier at times. When Guardians files a lawsuit and makes a bunch of people mad, a group like his can step in and talk with state regulators and businesses. Guardians essentially provides cover for groups closer to the political center, he said.

“Their advocacy pushes everybody, not just conservation organizations, kind of further to the left. And I think that’s good,” Rice said.

But there’s a downside. Lawsuits and sharply worded press releases can sting, and are not easily forgotten. And Rice worries that aggressive tactics from far-left groups lead to skeptical parties like ranchers or Front Range water managers lumping all environmentalists together.

“That has the potential to undermine the progress we’re making,” he said.

Looking To The Future

With the publication of last year’s Colorado Water Plan, a first for the state, officials are trying to turn the page on Colorado’s long fight over water. The plan, which officials describe as a roadmap to sustainability, stresses collaboration between competing interests and conservation of the increasingly precious resource.

“Now is the time to rethink how we can be more efficient,” Gov. John Hickenlooper said at the water plan’s introduction in November 2015.

Diverting more water should be the last-possible solution, Hickenlooper said. That’s welcome news to environmentalists like Matt Rice of American Rivers.

Rice said they are supportive of the Fraser River diversion plan for the same reasons Trout Unlimited is, though they aren’t part of the Learning by Doing group. But he hopes the Fraser diversion, and another major project in the works called Windy Gap, are the last trans-mountain diversion projects.

There just isn’t enough water on the Western Slope, he said. And if another one comes up, Rice said they’ll fight it with everything they have.

“We’re kind of at the cliff right now in the Colorado River Basin,” he said.

Collaboration and compromise will certainly be part of environmentalism’s future in Colorado. But as groups like WildEarth Guardians continue to find success in the courts, the advocacy ecosystem has room for other strategies too.

CWCB and city of Aspen oppose Maroon Creek Club water rights application

ASPEN – The Colorado Water Conservation Board and the city of Aspen are objecting to an effort by the Maroon Creek Club to broaden a 1989 water right so it can refill four ponds on its private golf course as it sees fit.

Both the CWCB and the city have filed statements of opposition in the water court case, which was filed in Division 5 Water Court on Aug. 10.

Maroon Creek LLC has told the court it is not asking to expand the 1989 water right, but is instead seeking “determination of surface water rights” regarding potential refill rights for four ponds, arguing that the 1989 right includes a refill option.

The ponds are usually filled once a year with water diverted from Maroon and Willow creeks, via the Willow Creek Ditch and the Herrick Ditch under the club’s 1989 water right.

But both the state and the city are concerned that in seeking such a determination, the club will actually expand its water right, and do so despite an earlier settlement agreement that sets a cap on the amount of water that the ponds can store in a year.

The four ponds can hold between 4.7 acre-feet to 13.6 acre-feet of water and altogether can store 35.1 acre-feet.

Two of the ponds are on the Buttermilk Mountain side of Highway 82 and two are on the clubhouse, or north, side of the highway. The ponds were built in the 1990s when the club’s golf course was shaped by a fleet of earthmovers.

Overall flow into the ponds, per the club’s 1989 water right decree, is not to exceed 4 cubic feet per second at any one time from the two irrigation ditches that feed them.

The Willow Creek Ditch can divert 10 cfs from Willow Creek, a tributary of Maroon Creek that enters at T-Lazy-7 Ranch. And the Herrick Ditch can divert 60.86 cfs from Maroon Creek, which is a tributary of the Roaring Fork River.

Maroon Creek LLC concedes the original decree is silent as to refill rights, but points to an amended 
application from the 1989 case that says “the reservoirs will be filled and refilled, in priority, as needed.”

“The explicit reference to reservoir refill indicates the original applicant’s intent to alter the presumptive one-fill rule with respect to the reservoirs,” states the “application for a determination” from Maroon Creek LLC. “Further, the reservoirs are on-ditch structures and are part of the greater Maroon Creek Club golf course. Keeping the reservoirs full through refill is ‘consistent with and implicit in the normal operation’ of key golf course ponds, which provides further evidence that reservoir refill was intended to be a part of the final decree in the original case.”

Attorneys with Garfield and Hecht in Glenwood Springs prepared the water court filing. And Andrew Hecht, a founder of and a partner in Garfield and Hecht in Aspen, is the manager of Maroon Creek LLC.

City and state file statements

The Colorado Water Conservation Board, which owns instream flow rights in Maroon Creek and the Roaring Fork and Colorado rivers, filed a detailed statement of opposition in the case on Oct. 27.

“The principle that reservoirs are limited to one fill per year is well-established in Colorado water law,” states a filing from the CWCB, prepared by attorneys general for the state of Colorado. “Therefore, absent specific language in a decree to the contrary, a decreed right to fill a reservoir is limited to a single filing per year.”

The CWCB argues that the 1989 water rights held by the Maroon Creek Club were the result of a stipulated agreement in the water court case that created the rights, and as such are explicitly limited to a single fill of each of the four reservoirs.

“The decree unambiguously awards a single fill,” the CWCB says.

And addressing any potential decision to the contrary, the CWCB told the court it “should reject an interpretation which is contrary to the long-accepted single-fill rule.”

The CWCB holds instream flow rights on Maroon Creek and on the Roaring Fork and Colorado rivers.

Water attorneys for the city of Aspen also filed a statement of opposition in the case.

“Aspen owns numerous water rights decreed for diversion from Maroon Creek and the Roaring Fork River and its tributaries, including certain water rights that Applicant [Maroon Creek LLC] has contracted for use on the property that is the subject of this application, which may be injured by the requested determination of surface water rights,” the city told the court.

As such the city says Maroon Creek LLC “must prove that the request for determination of surface water rights does not create a new water right or expand the decreed amount of use of the water rights” from the 1989 decree.

A status conference in the case is set for Dec. 22.

#ColoradoRiver: Moffat Collection System Project update #COriver

Denver Water's collection system via the USACE EIS

From The Wall Street Journal (Jim Carlton):

Next year, the U.S. Army Corps of Engineers is expected to decide whether to issue a permit to triple the capacity of Gross Reservoir in the Rocky Mountain foothills, with additional shipments of about 18,000 acre feet of water a year from the Colorado River watershed. An acre foot is enough water to meet the annual needs of an average family of five.

That is one of the last regulatory barriers for utility Denver Water’s $380 million project, for which district officials say they hope to break ground in 2019 to help ensure local water supplies.

“We have an obligation to supply water,” said Jeff Martin, Denver Water’s manager of the project, as he stood recently atop a 340-foot concrete dam that is to be raised by 131 feet under the plan. “It’s not an option to not have water.”

[…]

The Corps of Engineers is expected to decide next year on a proposed new “Windy Gap” project in Colorado, which would divert up to another 30,000 acre feet a year to the Front Range, the heavily populated area where the Rocky Mountains rise up from the plains.

In addition, more than 200,000 acre feet would be diverted for proposed projects in Utah and Wyoming…

Water officials in California and other lower basin states say they aren’t overly concerned about more diversions upstream, because a 1922 compact requires the upper basin states to deliver them about 7.5 million acre feet a year, or one half the river flow set aside for human use north of the U.S.-Mexico border. Much of that water is stockpiled in Lake Powell on the Arizona-Utah border.

With the Colorado running much lower than when the compact was signed, water experts say there is less water to divert.

“So long as their development doesn’t impinge on their release to us, that is their business,” said Chuck Cullom, a program manager at the Central Arizona Project in Phoenix, which pulls from the river and stands to lose a fifth of its deliveries if a shortage is declared on the Colorado. “If it falls below that, then they would have to figure out how to manage their demand.”

Don Ostler, executive director of the Upper Colorado River Commission, which oversees use of the river in the upper basin states of Colorado, Utah, Wyoming and New Mexico, agreed that new diversions increase the risk of shortages.

“The more you develop, the more a severe drought can affect you,” said Mr. Ostler. “But we are able to live with a certain amount of shortage.”

In Denver, water officials don’t feel they have much choice but to seek more Colorado water.

In 2002, tons of sediment from a forest fire clogged one of Denver Water’s reservoirs during a drought. “We came close to running out of water in the northern end of our system,” said Jim Lochhead, chief executive officer of Denver Water, a utility that serves 1.4 million people.

That crisis helped prompt the district in 2003 to undertake the Gross Reservoir expansion, which would store more water from an existing tunnel that transfers Colorado River water from the west side of the Continental Divide.

Denver officials pledged to only take the water in wet years and release more into streams when it is dry—measures that drew praise from some conservationists…

Gov. John Hickenlooper in July gave the state’s approval, calling the dam’s expansion vital. “The state’s responsibility is to ensure we do the right thing for Colorado’s future,” the Democratic governor said at the time, “and this project is vital infrastructure for our economy and the environment.”

#ColoradoRiver: Doing more with less water — Allen Best #COriver

From Aspen Journalism (Allen Best) via The Aspen Daily News:

Denver Water implements ‘Learning By Doing’ program in the high country

A decade ago, Kirk Klancke had hard, cold feelings about Denver Water. A stonemason for 35 years who moved to the Fraser Valley in 1971, he was passionate about the outdoors, particularly fly-fishing, and was outraged by depleted flows of the Fraser River and tributary creeks below a network of transmountain diversions.

Listening to Denver Water’s plans to step up diversions from these Colorado River tributaries, Klancke would seethe.

Today, Klancke almost gushes with compliments.

“Denver has been a treat to work with,” Klancke said one day in August at his home near Tabernash, located eight miles from the Winter Park ski area.

Denver Water still intends to divert more spring runoff. But what has won Klancke’s support is the utility’s commitment to an adaptive management program called Learning By Doing.

Part of the program includes about 30 people conferring weekly to address water issues in the upper Colorado River basin upstream from Kremmling, where up to 80 percent of the water may soon be diverted to the arid side of Colorado along the Front Range.

The conference call is modeled on a similar weekly call used to coordinate water deliveries, including from Ruedi Reservoir, to protect endangered fish in the Colorado River in the Grand Junction area.

During those calls, information is exchanged by water managers, and sufficient deliveries are usually ascertained. And decisions are made by consensus.

So far in the Learning By Doing effort, Denver Water has shown a willingness to juggle its diversions in response to conditions on the once-pristine streams in Grand County.

For example, in late July, Klancke noted warm water and dying fish in Ranch Creek, a tributary of the Fraser River. He told Denver Water about the low flows, but he didn’t really expect a response. To his surprise, utility officials offered to rejigger its diversions to make the flows in Ranch Creek last longer.

“It really helped Ranch Creek a lot,” says Klancke, the president of the Colorado River headwaters chapter of Trout Unlimited.

Learning By Doing is partly about manipulating diversions in the most environmentally friendly way possible, Klancke says. In the past, that wasn’t a concern “because they have just been operated like plumbing.”

The program is now gaining some notice in other headwater valleys, including the Roaring Fork, which is also substantially dewatered by transmountain diversions built in the 1930s and 1960s.

Pitkin County Commissioner Rachel Richards, who has focused for years on water issues, says Learning By Doing “clearly is a sound concept, modifying approaches based on science and data feedback. But we’re not sure we’ve seen enough actual implementation to judge whether it’s a valid tool.”

As you go

Learning By Doing is like a river trip without a precise itinerary. It acknowledges broad impacts to water-dependent ecosystems from Denver Water’s existing transmountain diversions and those of others. However, it doesn’t presume to know exactly how to lessen the impacts of existing diversions, let alone impacts of new ones.

The Moffat Firming project, which sparked the Learning by Doing effort, is being proposed by Denver Water. The nearby Windy Gap Firming project, on the main stem of the Colorado River below Granby, is a proposal from Northern Water. Both projects are part of Learning By Doing, although Northern is not a signatory to the underlying agreement for the program, the Colorado River Cooperative Agreement.

Both firming, or expansion, projects were conceived many years ago, but they were pushed forward after the 2002 drought. The drought crystalized Denver Water’s worries that it couldn’t supply enough water to its northern service area.

As such, Denver Water has proposed to divert more water from tributaries of the Colorado River and send it through its existing Moffat Tunnel system to an expanded Gross Reservoir, which is in the mountains southwest of Boulder.

The two big transmountain diversion systems in Grand County managed by Denver Water and Northern Water, plus several smaller ones, have annually removed an average of 67 percent of the water in the Colorado River below Windy Gap, according to the final environmental impact statement on the Windy Gap firming project.

The two proposed expanded diversions would bump that up to a combined 80 percent. By comparison, about 40 percent of water in the upper Roaring Fork and Fryingpan headwaters goes east, not west. That’s significant, but the upper Colorado River has been hit even harder.

The U.S. Army Corps of Engineers, the final decision-maker on both the expanded Moffat and Windy Gap diversions, now expects to issue decisions on the proposals in 2017.

The political landscape

The agreement that yielded Learning By Doing is grounded in political realities.
Denver Water needed Western Slope support to get more water. But to get it, the utility had to acknowledge a moral responsibility to address the impacts of existing diversions. That responsibility is now reflected in a legal agreement.

Denver Water initially submitted models about the effects of its proposed increased diversions. Trout Unlimited and other environmental groups were skeptical.

“A lot of water has been taken out of these rivers,” says Mely Whiting, an attorney for Trout Unlimited. “We were not convinced any model was going to be able to predict what would happen [with increased diversions] or what will happen with climate change.”

The message to Denver Water, she says, was “if you want more water, you have to fix problems we already have, and you have to make sure we don’t have more problems. That’s what we believe Learning By Doing is all about.”

Will the Colorado River actually end up being better off after the diversions?

“I think so,” Whiting says. “That’s the goal. That’s what we’re shooting for.”

But the upper Colorado River basin may never be as pristine as it once was.

“The goal is not to make it natural,” says Whiting. Instead, Learning By Doing aims to “make it better.”

Other environmental advocates reject this reasoning.

“Grand County got bad legal advice,” says Gary Wockner, executive director of Fort Collins-based Save the Colorado. “The river is already drained and depleted, and climate change is just going to make it worse. When you’re heading for a cliff in your car, the first thing to do is take your foot off the accelerator.”

Water conservation, Wockner contends, “is always cheaper, easier and faster than trying to build a massive new dam, as is buying and sharing water with farmers.”

Trout Unlimited sees things differently.

“We have said ‘yes, let’s conserve,’ and we do everything we can to really engage in pushing forward conservation,” Whiting said. “But we also need to figure out how to best protect the river with its projects moving forward.”

Might the parties that divert water from the Roaring Fork River watershed, which include Colorado Springs, Aurora and Pueblo, as well as irrigators in the Arkansas River Valley, ever feel a moral obligation to address the impacts of their diversions?

Chris Woodka, a former water reporter and the new issues management coordinator for the Southeastern Colorado Water Conservancy District in Pueblo,
was at least willing to consider the question last week.

Southeastern manages the Fry-Ark project, which diverts water from Hunter Creek and a string of tributaries in the upper Fryingpan River basin.

“We’re probably not going to suggest anything that would take less water,” Woodka says. “But if we are asked to do something, we would certainly look at it. But our primary obligation is to bring supplemental water to the Arkansas basin.”

And an important factor for the Roaring Fork watershed to consider may be this: Learning By Doing is the result of a proposal to increase transmountain diversions and is not simply born of a desire to better manage the streams already depleted by them.

Improving relations

Denver Water, the Western Slope, and environmental groups have long had an adversarial relationship.

And when the utility initiated the federal review process in 2003 for expansion of its transmountain diversions through the Moffat Tunnel, Eric Kuhn, general manager of the Colorado River Water Conservation District in Glenwood Springs, sent a proposed “global settlement” to Denver Water.

Denver Water rejected the specific proposal, but not the idea and submitted a counter-proposal in what then became an extended negotiation.

Soon, headwaters counties — especially Grand, Summit, and Eagle — came to agree that there had to be a global agreement among the affected counties in response to Denver Water’s proposal. Mediated negotiations began in 2007 involving 43 parties, most of them located on the Western Slope.

A key figure representing Grand County in the process was Lurline Underbrink Curran, a county native who became a planner and then the Grand County manager, a position she recently stepped down from.

Working with Denver Water, Curran decided, could yield more benefits than a courtroom brawl. But developing trusting relationships took time.

Curran, known for being plain-spoken and direct, credits the directors that Gov. John Hickenlooper appointed to the Denver Water board when he was mayor of Denver. She said they were able to acknowledge an important truth.

They were “willing to step back and go, ‘Well, we have had a huge impact and if at all possible we need to improve the area that we take the water from,’” she said.

Denver Water, in turn, shared modeling studies with Grand County after securing a promise that the models wouldn’t be used against it legally.

‘A really big deal’

Grand County also commissioned its own expensive stream management plan that brought science to the argument.
Paul Daukas, environmental planning manager for Denver Water, was impressed by that plan.

“It givers them the science, so they can frame their needs and wants in a scientific way,” he said. “That plan became the foundation for Learning By Doing.”

Learning By Doing is included in the 2013 Colorado River Water Cooperative
Agreement, the result of the long negotiating process with Denver Water.
And Curran says Learning By Doing puts Grand County, with its multiple tasks, on par with Denver Water, an agency with a singular focus.

“That is a really big deal,” Curran says.

Denver Water and the Windy Gap sponsors aren’t legally required to participate in Learning By Doing until they get all their federal permits.

Nonetheless, in 2011, they joined the state, Grand County and other partners to begin to explore how to do more for rivers with less water.

Diminished flows distress the web of life found in rivers. Macroinvertebrates — bugs — live in the gaps between rocks in rivers. Reduced flow means less velocity, and sediments are not swept from between the rocks. Less room for bugs means fewer of them, and fewer bugs means fewer fish.

Klancke, the avid fly-fisherman, can point to reaches of river in Grand County where President Dwight Eisenhower snagged big trout during summer vacations in the 1950s.

But now he can also point to segments of the Fraser River where summer flows, depleted by diversions, are too shallow for the width of the channel, resulting in water dangerously warm for fish and the bugs they depend upon.

“They heat up in ways they never did before,” says Klancke of the tributaries in Grand County. “Seventy degrees is the limit trout can withstand.”

One recent response has been to narrow a section of the Fraser River’s channel for nine-tenths of a mile and add riffles and pools. The ongoing Fraser Flats project will cost $201,000, with various parties, including a private landowner, chipping in.

Denver Water’s portion of the Fraser Flats project is only $50,000, part of $2 million earmarked for aquatic habitat improvements under the Colorado River Cooperative Agreement. The agreement says that Denver Water will provide $11 million to Grand County in all.

That agreement also obligates the utility to bypass 1,000 acre-feet that it could divert. The water is to be used for environmental purposes in the Fraser Valley.
After the work is done at Fraser Flats next year, stream temperatures and other indicators will be monitored for several years.

The procedure, explains Denver Water’s Daukus, is to see what benefit has occurred, “so that when we go to the next project, we can see what has worked and what won’t work.”

But Wockner of Save the Colorado thinks Grand County settled for a “terrible deal.”

“The two dam and diversion projects would take over a billion dollars of water over to the Front Range,” he says, referring to the Moffat and Windy Gap firming projects.

“Grand County settled for about one percent of that in mitigation costs, which is a fleecing of money as well as water.”

As for the “channel enhancement” at Fraser Flats, he sees only a narrowed irrigation ditch.

“The Fraser and Colorado rivers need more water, not less,” Wockner says.

Still, proponents say Learning By Doing provides a model. They say it requires commitment by people to be stewards of rivers in their backyards. It requires mechanisms for addressing problems. It requires cooperation among diverse partners. And it requires compromise.

Denver Water’s most important change, says Klancke, may be a new focus. Instead of a singular focus on delivering water to customers it may now have a broader focus that includes maintaining the health of the basin of origin, he says.

“That’s the culture they’re changing,” he said. “I won’t say it’s successful until the scientists say it’s healthier than it used to be. But we’re headed in the right direction.”
Richards, of Pitkin County, is still not sure Learning By Doing has sufficient teeth to compel change.

“It will depend,” Richards said, “on whether what is learned actually ends up changing what the water diverters do.”

From The Public News Service:

Wyoming has moved one step closer to getting more water for ranching, agriculture and industrial development.

The U.S. House Committee on Natural Resources has advanced a bill that would allow the state to take an additional 125,000 acre-feet of water from the Green River at the Fontenelle Dam…

State officials say expanding the Fontenelle is necessary for farmers and ranchers who need a reliable water supply to keep crops and livestock healthy.

They feel the measure would also be an economic incentive for new businesses to grow and create jobs in southwestern Wyoming…

[Gary Wockner] notes Wyoming isn’t the only state trying to get more water from a shrinking source.

He points to a proposal by Denver Water to expand the Gross Dam that would remove an additional 5 billion gallons annually from the Colorado.

While upper-basin states may technically have rights to the water, Wockner says the challenges of a changing climate and 16 years of drought can’t be ignored.

#ColoradoRiver: “Killing the #Colorado” spotlights new solutions — American Rivers #COriver

killingthecoloradotrailerscreenshot

From American Rivers (Sinjin Eberle):

I have noticed a lot of chatter lately about the situation at Lake Mead. Dramatic overuse, prolonged drought, and the effects of increased temperatures have led to a historically low volume of water stored in the largest reservoir on the Colorado River. One of the most critical components of water in the west is less than 40% full. Yet while some people scramble for a quick fix or point fingers, others see the long game and note the optimism that working together for smart, sustainable solutions can bring. There is hope, there is a roadmap, and together we have the knowledge, skill, and foresight to make it happen.

The Discovery Channel recently produced a new documentary, Killing the Colorado, a made-for-TV version of the lengthy ProPublica series of the same name. The show is excellent, comprehensive, and features a number of voices that you may not expect to be featured in a film about the environment. Imperial valley agricultural producers, water managers, a red-state Senator and a blue-state Governor – all identifying problems facing the basin, and most putting forth an optimistic view that a human-caused predicament can be solved with human-inspired ingenuity.

One quote in particular is poignant – there is a scene with Colorado Governor John Hickenlooper in his office flipping through a binder full of historic water compacts. Upon his observance of the generations of water agreements, he remarks “The thing you realize when you go through these [water] compacts, is that everyone is in this together.” Given the situation facing Lake Mead, a growing chorus of voices around Lake Powell, the birth of the Colorado Water Plan, and a recognition that heathy rivers support healthy agriculture and sustainable economies, we truly are all rowing the same boat together in the Colorado Basin.

But, how can Lake Mead affect Colorado from a thousand miles downstream? Well, due to the Colorado River Compact of 1922, headwaters states like Colorado must send a certain amount of water to the Southwestern states of Arizona, Nevada, and California – it’s the law of the river, and the law of the land. And since when the Compact was developed, California was a fast growing destination, it has priority and can “call” for water if needed. For years, California has had the luxury to get much of the surplus of water that Colorado and Wyoming have sent downstream to be stored in Lake Powell and Lake Mead. But now with prolonged drought, a fast-growing population across the entire Southwest, and a substantial agricultural economy (especially in the Imperial Valley), the era of surplus water is over. As such, Lake Mead is directly connected to Colorado, whether we like it or not, and that connection is the Colorado River.

Killing the Colorado does a fantastic job over nearly an hour-and-a-half of highlighting a variety of colorful characters who have recognized that shortage and a lack of water will change everything in the future – that future is now. But while both the show and the written article are excellent at highlighting the situation, they don’t delve deeply into what I think is most important – that real solutions do exist, and we know how to implement them, it simply takes our collective will to get them moving. Solutions like urban and agricultural conservation and efficiency, like reuse and recycling, like innovative water banking and flexible management practices, like continuing the shift towards renewable energy (solar and wind don’t devour cooling water like natural gas and coal plants require). But while these efforts all seem daunting and out of an individual’s control, there are actions that each of us can take every day that together, make a huge difference. Like buying and installing your own rain barrel for your outside plants and flowers, like supporting your local farmer at the farmer’s market – small things that have a great impact, especially when we all do them together.

Solutions do exist, and as Arizona Senator Jeff Flake said “The drought over the past couple of years has awakened all of us to the future we have if we don’t do better planning. There are many things that are out of our control…Planning is so important. Conserving. Recharging. Water banking. Water markets. These are all important things that have to take place.

Let’s get started!
