#ColoradoRiver District to release water for Grand Valley irrigators, Fryingpan and Roaring Fork will benefit

From The Grand Junction Daily Sentinel (Dennis Webb):

The Colorado River District has agreed to boost water levels to help fish in the Roaring Fork River watershed while also conserving water for use by local irrigators later in the season and improving the chances for boosting flows this fall for endangered fish.

The action also could help protect water quality in the case of anticipated ash in waterways due to expected flooding and debris flows resulting from the Lake Christine Fire near Basalt.

The river district is releasing water from Ruedi Reservoir above Basalt to boost flows in the Fryingpan River and Roaring Fork River to help reduce water temperatures to benefit trout. Low flows and warm temperatures in western Colorado have led to Colorado Parks and Wildlife urging anglers to avoid fishing later in the day on numerous western Colorado waterways due to the stress trout currently are facing.

The U.S. Bureau of Reclamation approved the river district releases last week. They are expected to range between 50 and 100 cubic feet per second.

River district spokesman Zane Kessler said the water to be released is owned and managed by the river district’s enterprise…

The water technically is being delivered downstream for Grand Valley irrigation needs but is creating environmental benefits on its way there. The water otherwise would have been delivered from Green Mountain Reservoir south of Kremmling.

Kessler said the Ruedi releases will allow for conserving a part of what’s called the historic users pool at Green Mountain Reservoir for use later in the season, which would benefit Grand Valley irrigators. The releases also increase the chances that, despite it being a dry year, that pool can be declared to have a surplus. That surplus could then be delivered in September and October to what’s known as the 15-Mile Reach, a stretch of the Colorado River in the Grand Valley where the flows would benefit endangered fish.

“This has never been done before,” Kessler said of the flow agreement. “But we’ve rarely seen river levels like this before either.”

The potential for easing the impacts of ash flow also could be felt in the Grand Valley. There is concern that ash flows could force the Clifton Water District to suspend use of Colorado River water. Area water providers have an agreement to help each other in meeting short-term water needs should that kind of emergency situation arise, but doing so this year would further deplete drought-stressed supplies.

Kessler said retaining some Green Mountain Reservoir water for release later in the year also could benefit recreational uses of the Upper Colorado River.

Meanwhile, the river district is taking another step aimed at helping ensure that benefiting fish in the Roaring Fork Valley doesn’t harm fish on the Colorado River upstream of the Roaring Fork confluence. The district is currently delivering what Kessler called “fish water” from Wolford Reservoir north of Kremmling into the upper Colorado River because it is having to lower the reservoir’s water level in preparation for doing some work on the dam there.

Heeding science in managing the #ColoradoRiver — The Mountain Town News #COriver

From The Mountain Town News (Allen Best):

A time of big pivots for Colorado water — with yet another reckoning to come

Eric Kuhn is now retired as general manager of the Colorado River Water Conservation District, but he may be working on the most important project of his career, a book.

In that book, working with John Fleck of Albuquerque, he’s trying to make the case that science should not be ignored in figuring out how to manage the Colorado River during the 21st century—as it was when Congress approved the 1922 compact governing allocations among the seven states, Indian tribes, and, somewhat more fuzzily, Mexico.

Kuhn was honored recently in Glenwood Springs by his staff and others from around Colorado for his 37 years of work.

Trained as an electrical engineer, Kuhn had been a naval office on a nuclear-powered submarine before pursuing a career in nuclear power plants. But even in 1981, he could see that nuclear power wasn’t going in the right direction. When he noticed an advertisement in the Wall Street Journal for a position at the Glenwood Springs-based water district, he applied.

Obviously, he got the job, moving from energy to water, from California to Colorado.

It was sharp pivot in Kuhn’s life. And Colorado since 1981 has also pivoted hard in very fundamental ways in its conversations about water.

Tom Alvey, who grows fruit and operates a packing shed in Hotchkiss, credited Kuhn with providing transparency and “getting the facts right” during his time as general manager of the Colorado River Water Conservation District, beginning in 1996.

Bill Trampe, who owns a ranch that sprawls between Crested Butte and Gunnison, lauded Kuhn for having “the foresight to see where we were headed and what we needed to do to be effective in protecting water for the Western Slope.”

Peter Fleming, the river district’s general counsel, testified to Kuhn’s “highly intellectual approach to negotiations.” As arguments and counterarguments were waged at one session, said Fleming, he observed Kuhn scribbling into a notepad. Peering over his boss’s shoulder, he said, he saw numbers. What did they represent? “He was calculating complex integers,” Fleming discovered. In that scribbling could be seen a larger lesson.

“He wasn’t disinterested in what was going on,” said Fleming. “He just knew that the timing wasn’t right for him to offer what would inevitably be a good solution.”

Denver Water’s Jim Lochhead was also at the gathering in Glenwood, just a few blocks from where he had for many years staffed the “Aspen office” of one of the state’s leading law firms. Lochhead drew attention to Kuhn’s influence beyond Colorado’s traditional Eastern Slope versus Western Slope schisms to the broader seven-state Colorado River Basin. There, Kuhn’s voice about preparing for a warming climate has become influential.

“He is collaborative. He is innovative. He thinks about different solutions. He listens. He tries to find the common ground,” said Lochhead, now chief executive of Denver Water, an agency that provides water to 25 percent of all Colorado residents.

A time of pivots

Nobody, however, spoke directly to the giant pivots in water politics, policies and problems in the 37 years since Kuhn arrived in Colorado.

One of the largest pivots had already begun in 1981. The federal government had spent most of the 20th century building the giant dams, canals and other hydraulic infrastructure in the West. In Colorado, the greatest ambition was evident in the gigantic transfer of water from the Colorado River headwaters near Grand Lake to the benefit of farmers in northeastern Colorado. It’s called the Colorado-Big Thompson Project.

The transfer—some would call it a heist — was opposed on the Western Slope, of course. One result of the compromise was a 1937 state law that created the river district and charged it with “conservation, use and development of water in the Colorado River and its principal tributaries in Colorado.” It covers 15 counties, including Pitkin, Garfield and Eagle. Southwestern Colorado has a similar district.

Another outcome was federal construction of Green Mountain Reservoir, on the Blue River north of Silverthorne. The dam had immediate benefits to the Western Slope, helping regulate flows to the benefit of farmers around Grand Junction. Much later, the regulated flows were crucial to providing water for endangered fish species in the Colorado River.

A later enterprise, the Fryingpan-Arkansas Project, hewed to the same template: It diverts water from the Roaring Fork drainage to farmers in southeast Colorado. For this, the Western Slope got Ruedi Reservoir. It was completed 50 years ago.

More projects were proposed, but in 1977 President Jimmy Carter announced they wouldn’t get funded. Westerners bristled and ridiculed Carter as a peanut-farmer in rain-drenched Georgia who didn’t understand the West. Ronald Reagan, arriving at the White House in 1981, was heralded as a Westerner who would right things. He only went half-way: Locals would have to come up with half the money for their dams and diversions. For most projects, it wasn’t nearly enough.

Kuhn noted that during his time, two of the five projects on Carter’s hit list in Colorado were eventually built, if not to the sizes originally envisioned. One of them, Ridgway Reservoir (originally called Dallas Divide), provides hydroelectricity that is part of Aspen Electric’s 100 percent renewable portfolio.

Altogether, however, the river district during Kuhn’s time had a hand in building five smaller-size reservoirs. Wolford Mountain Reservoir near Kremmling, by far the largest, is two-thirds the size of Ruedi. It was built in co-operation with Denver Water.

The River District under Kuhn also worked with Denver Water on other projects. But when Kuhn started work in Glenwood Springs, the relations were rocky. Denver wanted to build a giant dam in the foothills southwest of the city. Two-thirds of the water behind the Two Forks Dam was to have come from the Western Slope, primarily Summit County. Water was to go to Denver’s fast-growing suburbs.

Kuhn had been assigned to represent the river district on a task force appointed by then-Gov. Dick Lamm, to help sort through the controversy. The Western Slope task force aligned with the environmental community and together they conceded need for a small Two Forks as well as expanded diversions from Winter Park area for an enlarged Gross Reservoir west of Boulder. In exchange, the task force said, Denver needed to commit to greater water conservation. Denver Water’s leaders, confident of their rightness to the point of cockiness, refused.

The drama was cut short in 1991 when the administration of President George H.W. Bush vetoed the project, which was to be on federal land, based on environmental impacts.

Kuhn points out that the levels of conservation the Western Slope and environmentalists asked of Denver were much less than what has actually occurred. Denver Water now uses the same water for roughly double the number of people it did in 1990. The default expectation of ever-more water supplies has been shattered.

“You have this decoupling of municipal growth and water use, and we really didn’t see that coming in the early 1980s,” Kuhn said in an interview last week.

Denver, Aspen and other communities have been part of a national trend of declining per-capita use of water that may be far from over. It’s a simple matter of economics. Wringing the sponge of water conservation is cheaper. More expensive is buying water from farms on the Great Plains, but it’s still cheaper than developing new supplies.

Still being debated is how much water Colorado has to develop out of its entitlement, under compacts governing the Colorado River. As with Two Forks, a notion that the solution to water shortages is to build more dams and divert more still lingers. It assumes water remains available. A state report issued several years ago concluded that Colorado had as much as 1.5 million acre-feet of water in the Colorado River to develop.

Kuhn scoffed at that estimate. He said then that no more than 150,000 acre-feet remained—and, quite possibly, not even that. Even allocations for existing water uses are questionable because of the dangling uncertainty of the warming climate.

After rummaging around climate change science beginning in about 2000, Kuhn became increasingly vocal through published papers and other work about the need to recognize the profound implications of a warming climate on water supplies in the Colorado River and the demands.

“I was just reading some of the work that was coming out in the early 2000s, and it’s largely proven to be generally correct,” he said last week. “I am surprised how quickly it has come on, because there is so much noise in the system,” he added, referring to the inherent variability of weather, both temperature and precipitation. “Even from one year to the next there can be a lot of noise.”

A cloudy crystal ball

What this means exactly for Colorado is still hard to say. There’s still too much uncertainty about impacts to justify significant infrastructure investments at this time, according to even Denver Water. Kuhn agrees.

“It will take a long time to see how that pattern (of change) sets up,” he said.

Climate modeling suggests—but with low confidence—less snow and precipitation for southern Colorado and more for northern Colorado. The Elk Range between Aspen and Crested butte can be seen as a divide between that wetter and drier future.

“If I were in the southwest, in Durango, I would be a heck of a lot more concerned than if I were in Steamboat Springs, based on what we know now—but it’s still a guess,” he said.

Just inside the Mexican border, at San Luis Rio Colorado, nothing remains of the Colorado River except for its sandy bed. Photo/Allen Best

For the broader Colorado River Basin, though, Kuhn expects less water in the Colorado River as it flows into the Grand Canyon past Lees Ferry. In this, last winter was a harbinger of the future. There are profound implications for how the seven states of the Colorado River Basin – plus Mexico—move forward.

And that is the big idea for the book now being written. In it, he and Fleck point to a report issued before the Colorado River Compact was formally adopted by Congress in 1928. The framers of the compact had assumed 16.4 million acre-feet average flows in allocating the waters among the seven basin states — with more yet due Mexico. In fact, flows during 20th century proved to be somewhat less, about 15 million acre-feet. The report provided accurate evidence of lesser flows beginning in 1875 and, more circumstantially, to 1850.

In other words, it was wishful thinking to assume so much water — and based on what is known about global warming, it’s fair to assume even less water in the 21st century. Through the first 14 years of the century, according to the research of Brad Udall and Jonathan Overpeck, flows have declined 19 percent.

“It’s a story about ignoring inconvenient science,” Kuhn said of the book. “If you had accepted the science, it would have made the political job [of apportioning the waters] much more difficult.”

It’s a story from a century ago, he said — but one fully relevant going forward.

@USBR approves “coordinated” approach to increase #ColoradoRiver streamflow in the Grand Valley #COriver

From The Aspen Times:

The Colorado River District is working with state and federal water managers to increase flows in the Fryingpan River by as much as 100 cubic feet per second (cfs), helping trout in the watershed survive warm temperatures while supplying water for downstream irrigation needs in the Grand Valley.

Anticipated releases are expected to range between 50 cfs and 100 cfs and will be coordinated between the River District, the U.S. Bureau of Reclamation and the U.S. Fish and Wildlife Service to increase flows in the Fryingpan and Roaring Fork rivers downstream from Ruedi Reservoir.

“This should significantly benefit flows below Ruedi Reservoir,” said John Currier, chief engineer for the district. “We expect that the supplement flows may also help to mitigate water-quality problems anticipated from fire-related ash and debris flows stemming from the Lake Christine Fire on Basalt Mountain.”

Technically, the water will be delivered downstream for Grand Valley irrigation needs while creating environmental benefits as it flows downstream. Green Mountain Reservoir releases will be reduced by an equal amount in order to conserve storage for late-season releases, which in turn will be needed to help endangered fish near Grand Junction.

The coordinated approach was given final approval by the Bureau of Reclamation on Monday. In order to boost Fryingpan levels while the plan awaited approval, the U.S. Fish and Wildlife Service implemented a 50 cfs release from its dedicated endangered fish pool in Ruedi on Friday. Those flows were supplemented by 30 additional cfs Monday, bringing the flow in the Fryingpan to 200 cfs.

Both Ruedi and Green Mountain reservoirs contribute water to the Upper Colorado River Endangered Fish Recovery Program. In this case, the changed water release plan will benefit trout below Ruedi while endangered fish still receive water from upstream Colorado River reservoirs.

Increased flows of cold water out of Ruedi should also help to alleviate some stress on trout fisheries in the watershed brought on by higher-than-normal water temperatures. Colorado Parks and Wildlife announced voluntary fishing closures earlier this month on sections of the Colorado and Roaring Fork rivers.

2018 #COleg: HB18-1008 Mussel-free Colorado Act status update

From The Summit Daily (Deepan Dutta):

Should the non-native quaggas infest the [Green Mountain Reservoir], millions in taxpayer money will be spent to ensure they do not clog or damage water infrastructure, as well as to prevent destruction of the aquatic ecosystem and the associated recreational fishing industry.

The danger posed by this critter is so high that Colorado Parks and Wildlife, the U.S. Forest Service, the Bureau of Reclamation, Summit County and other agencies are combining efforts to make sure the quagga does not wind up ruining the reservoir as it has other water bodies in Colorado.

Legislatively, a bill called the “Mussel-Free Colorado Act” dedicated to eradicating quagga and zebra mussels is well on its way to becoming state law. The bill requires boat owners to purchase an aquatic invasive species sticker on top of their regular boat registration to fund mussel prevention measures.

County Commissioner Karn Stiegelmeier has been following developments at the reservoir intently since last August, when the Bureau of Reclamation discovered quagga veliger, or larvae, in the reservoir. At the time, Stiegelmeier said she was furious with the lack of federal funding to pay for boat inspections preventing mussel infestation in the first place.

“Other reservoirs like Dillon Dam and Wolford are taken care of by the responsible dam owners,” Stiegelmeier said. “They pay for regular boat inspections before they get in the water, as they should. But the federal government reservoirs always contract out recreation and claim it’s not their job to making sure boats aren’t contaminated before they launch.”

DECONTAMINATION

Federal authorities were put on high alert and finally turned their attention to Green Mountain once mussel larvae was detected. Stiegelmeier said that it will be a much more expensive endeavor to try to ward off infestation after it starts.

“Once a reservoir is infested, the feds wind up having to pay many times as much to deal with the infestation,” she said. “Once the adult mussels get in there you can’t get rid of them. We have a huge number of reservoirs, like Lake Powell, that are infested. It costs an enormous amount of money to get mussels off the dam infrastructure, and it absolutely destroys the aquatic ecosystem.”

While samples at Green Mountain have come back clean since the initial detection, Bill Jackson, head of the U.S. Forest Service’s Dillon Ranger District, said that concern over quagga is far from over…

Jackson said that to prevent the infestation, the Forest Service and other agencies will monitor water at Green Mountain for at least three years — the maximum amount of time quagga need to fully develop. The agencies are also working to divert all incoming boat traffic to a single launch point at Heeney Marina, where they can be centrally inspected and decontaminated before reaching the water. Jackson said that one major risk factor for contamination was how many boats were previously launched from unauthorized areas along the shoreline.

“We had a lot of motorboat launches into the reservoir without proper inspection and decontamination,” Jackson said. “We’ve really been trying to make sure that we got on that right away to prevent folks from doing that.”

Jackson said that the Northern Colorado Water Conservancy District, which gets some of the water from the reservoir, helped in providing rocks, boulders and other implements to block off the known boat entry points. He also said that signage will be put around the reservoir directing boat owners to proper launch points where they will be inspected and decontaminated before hitting the water.

In the months leading to boating season, Jackson said that a major collaborative project will be taking place to improve the inspection and decontamination process at Green Mountain.

The Bureau of Reclamation and other partners will help Heeney Marina to improve its boat launch facilities and parking to accommodate the large amount of boat traffic being funneled there. The Forest Service will do its part by allowing modifications to the marina’s permit for construction there, as it operates on Forest Service land.

The project will also require Summit County to help by closing down and improving the county roads leading into and out of the reservoir, as well as introducing more signage. Details of the project have yet to be released in full to the public, but Jackson said a press release is forthcoming.

Jackson added that they needed the public’s help in preventing contamination.

“If folks are not getting their boats inspected, that doesn’t help anyone, and we wind up dealing with the aftermath of cleanup efforts. Prevention is where we want to be.”

Jackson said that boat owners can help by following a three part procedure: Clean, drain and dry.

#Colorado congressional delegation sends quagga SOS to Zinke et al.

Green Mountain Reservoir via Reclamation.

From The Denver Post (Jesse Paul):

Nearly every member of Colorado’s congressional delegation has signed a letter to the Trump administration asking for help with the emerging crisis of tiny invasive mussel larvae found in Green Mountain Reservoir…

“We urge you to respond rapidly, deploy available resources and work with the state and local communities to prevent this initial detection from growing into a full infestation,” the delegation wrote to Interior Secretary Ryan Zinke. “A rapid response is critical during the window of opportunity immediately after the detection of invasive species.”

The letter, dated Thursday, was signed by Sens. Cory Gardner and Michael Bennet, as well as Reps. Diana DeGette, Scott Tipton, Doug Lamborn, Jared Polis, Ed Perlmutter and Mike Coffman.

Rep. Ken Buck, a Weld County Republican, did not sign the letter.

“As a headwater state that is currently free of adult invasive mussels, the detection of invasive mussel larva poses a tangible threat to our economy,” the letter said. “The Department of Interior has recognized the importance of preventing invasive mussel infestations in western headwater states, such as Montana where larva was identified in late 2016 and resources were deployed to the Columbia River Basin.”

Zinke is from Montana.

Colorado Parks and Wildlife spokesman Mike Porras said his agency has drawn more than 100 samples from Green Mountain Reservoir since the larvae were detected. “All of these samples have come back negative for all aquatic nuisance species including quagga mussels.”

[…]

Tiny mussel larvae, known as veligers, have been found in Colorado before. Lake Pueblo, for instance, tested positive for them in 2007, 2008, 2009 and 2011.

Biologists, however, have never found an adult zebra or quagga mussel in any Colorado lake or reservoir.

Lake Powell, which straddles Utah and Arizona, has been ravaged by a mussel infestation since veligers were detected in late 2012 and four adult mussels were found on a boat that had been pulled for service in March 2013.

Boats and other watercraft can quickly spread the invasive species. Colorado wildlife officials have said the veligers found in Green Mountain Reservoir likely hitched in on a boat that had been in water outside the state.

State lawmakers during the past legislative session cited the threat of invasive mussels as one reason why they voted down a proposal to allow sea planes on Colorado’s bodies of water, saying they could act as long-range vehicles for the species.

State and federal agencies find evidence of quagga mussel veligers in Green Mountain Reservoir

Here’s the release from Colorado Parks and Wildlife (Lauren Truitt):

Monitoring finds Evidence of Quagga Mussel Larvae in Green Mountain Reservoir

State and federal officials have confirmed the presence of invasive quagga mussel larvae, known as veligers, in Green Mountain Reservoir located in Summit County along Hwy 9 between Silverthorne and Kremmling.

On Aug. 18, as part of a state and federal initiative to monitor aquatic nuisance species in the state, specialists with the Bureau of Reclamation first confirmed the presence of the veligers, initially through microscopic analysis followed by DNA testing. An independent laboratory contracted by Colorado Parks and Wildlife confirmed Reclamation’s findings. It is unknown if the veligers were dead or alive at the time of detection.

CPW immediately increased monitoring of the reservoir for all life stages of quagga mussels. Through a partnership with the Denver Aquarium, CPW’s volunteer ANS scientific scuba dive team surveyed the reservoir last Friday and did not find any evidence of invasive mussels. No adult zebra or quagga mussels have ever been found in Green Mountain Reservoir or anywhere in the state of Colorado, although eight different reservoirs in Colorado have been temporarily suspect or positive for mussel veligers since 2008.

“Although this is very troubling, it’s important to keep in mind that the reservoir is not considered infested, a designation given only to bodies of water that have extensive and reproducing adult populations,” said Elizabeth Brown, invasive species coordinator for CPW. “At this point, Green Mountain Reservoir is only considered ‘suspect,’ not positive. A body of water can be considered ‘positive’ only after a second independent specimen collection is obtained and the genetics confirmed by two independent laboratories, which has not yet occurred.”

Officials are most concerned about the possibility that the presence of veligers could eventually lead to a major infestation. This would put the reservoir’s hydroelectric power generation, water quality, drinking water delivery and recreation at risk.

“This is an unfortunate discovery, and something we have been working very hard to prevent,” said CPW Director Bob Broscheid. “It shows why we need a robust inspection program. As more and more people move to or visit Colorado and use our water resources for boating, we must continue to work hard to prevent the spread of these harmful invasive species. We cannot overstate how serious this is.”
All ballast boats, inboard and inboard/outboard engines must have a green seal in between launches or decontamination may take place prior to launching. Boaters are encouraged to inspect their own boat between every use and make sure it is clean, drained, and dry.

The State of Colorado requires boats to be professionally inspected if:

  • a boat has been in any body of water that is positive, or suspect for ANS
  • a boat has been in any body of water outside of Colorado
  • a boat will be entering any water body where inspections are required
  • Officials are unsure how the veligers entered the water but suspect a boat that visited an infested body of water in another state may have become contaminated, then launching illegally into Green Mountain Reservoir.

    “This situation demonstrates the importance of following the law and going through the required inspection and decontamination process upon entering and exiting bodies of water,” said Reid DeWalt, Assistant Director Wildlife and Natural Resources with CPW. “We could face the possibility of a very harmful infestation that could cause severe damage to the reservoir and its infrastructure.”

    The watercraft inspection and decontamination station at Green Mountain Reservoir is operated by the Heeney Marina and funded by a partnership between CPW and the U.S.Forest Service. The station has now begun implementing containment protocols which means that every boat has to be inspected when exiting the reservoir and will be issued a seal and blue receipt. If a boater leaving Green Mountain Reservoir intends to launch in a different water body, their boat must be decontaminated before launching by a certified professional.

    Cooperation with Colorado’s mandatory inspection and decontamination program has proven successful to stop the movement of harmful invasive species, such as quagga mussels, into new waters. Public awareness and participation is the best weapon in the prevention of invasive species. Invasive mussels severely endanger our water supply for drinking water, hydropower, agriculture, recreation and natural resources.

    “It is everyone’s responsibility to take care of our natural resources,” said Karn Stiegelmeier, Summit County Commissioner. “This news is certainly difficult to hear with the amount of effort and diligence we have put into the ANS program on the reservoir. We will continue working alongside our partners to make sure we educate residents and visitors of the importance of decontamination of boats before and after they are on a body of water. This can be prevented, but we need everyone’s participation.”

    Boaters are reminded to take the simple precaution of making sure that they clean, drain, and dry their boat every time they go boating. Due to financial constraints the state does not have additional inspectors that can be sent to assist with boat inspections at Green Mountain. Going into a holiday weekend state and federal officials are asking for the public’s help to prevent invasive species.

    “We know this is an extra step for those who have come out to enjoy recreating on the lake, but staying vigilant has proven to be effective throughout Colorado,” said JT Romatzke, NW Region Manager with CPW. “We need to make sure we are balancing our recreation with the integrity of our water resources.”
