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.

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.”

    #Runoff news: Coordinated releases for #ColoradoRiver endangered fish #COriver

    From the U.S. Fish and Wildlife Service via The Los Alamos Daily Post:

    Coordinated releases from a series of Upper Colorado River Basin reservoirs began Saturday, June 3, and are anticipated to continue through this week as part of the Coordinated Reservoirs Operations Program.

    The US Bureau of Reclamation, the Colorado River District, Denver Water and Northern Colorado Water Conservancy District as owners and operators of upper Colorado River reservoirs have mutually agreed to modify their operations to benefit the endangered fish of the Upper Colorado River Basin.

    The Coordinated Reservoir Operations (CROS) program was established in 1995 as part of the Upper Colorado River Endangered Fish Recovery Program. The purpose of the Coordinated Operations is to enhance spring peak flows in a section of the Colorado River upstream of Grand Junction, Colo. Determined to be critical to the survival of four endangered fish species: the Humpback Chub, Razorback Sucker, Bonytail and the Colorado Pikeminnow. The higher peak flows remove more fine sediment from cobble bars that serve as spawning habitat for the endangered fish. In years with sufficient snowpack, surplus inflows to the reservoirs can be passed downstream to benefit these fish without impacting reservoir yields or future beneficial water uses.

    Coordinated Reservoir Operations were most recently conducted in 2016, 2015 and 2010. In 2011 and 2014, wet conditions caused streamflows in certain areas of the basin to approach or exceed levels associated with minor flooding, so CROS was not performed. In 2012 and 2013, reservoirs did not have surplus inflow to contribute due to extremely dry conditions.

    Managers of the reservoirs completed a conference call June 2, agreeing to voluntarily run the program this year. Planned reservoir operations as of June 2 are described below. Release and flow amounts are approximate. Most reservoirs will step up releases over the next several days, hold at a constant rate for 3-7 days, and then wind down releases.

    Green Mountain Reservoir, operated by the Bureau of Reclamation, will increase releases from 418 cubic feet per second (cfs) to powerplant capacity of around 1400 cfs. Releases from Green Mountain include inflows bypassed by Dillon Reservoir, operated by Denver Water, that will be increased by approximately 100 cfs during CROS.

    Denver Water also operates Williams Fork Reservoir, which is releasing 200 cfs. Releases will likely increase to approximately 600 cfs over the coming week to bypass increasing inflows.

    Willow Creek Reservoir, operated by the Bureau of Reclamation and Northern Colorado Water Conservancy District, is releasing 90 cfs. Releases will increase this week to roughly 600 cfs by curtailing pumping operations to Granby Reservoir and bypassing those inflows instead.

    Wolford Mountain Reservoir, operated by the Colorado River District, is passing inflows of 350 cfs. Outflows will be increased to around 600 cfs for approximately five days.

    Ruedi Reservoir, operated by the Bureau of Reclamation, is releasing 182 cfs and will increase releases to approximately 600 cfs over the next few days.

    The Colorado Basin River Forecast Center (CBRFC) will incorporate these planned reservoir operations into their streamflow forecasts. Based on weather forecasts and planned reservoir operations, flows in the Colorado River near Cameo (upriver of Palisade, Colo.) are anticipated to be approximately 14,000 – 17,500 cfs, June 7 through June 12, with the highest flows Thursday or Friday June 8 or 9. Flows in the forecasted range are still below defined “bankfull” and flood stages for the area.

    More detailed information about forecasted streamflows in the Colorado River basin are available from the CBRFC website at http://www.cbrfc.noaa.gov. A map-based interface allows viewing of hydrographs detailing recent, current and anticipated flows.

    For more information, contact Don Anderson, U.S. Fish & Wildlife Service, at 303.236.9883, donald_anderson@usfws.gov, Michelle Garrison, Colorado Water Conservation Board, at 303.866.3441, ext. 3213, michelle.garrison@state.co.us or James Bishop, Bureau of Reclamation, at 970.962.4326, jbishop@usbr.gov.

    The Upper Colorado River Endangered Fish Recovery Program is a cooperative partnership of local, state and federal agencies, water developers, power customers and environmental groups established in 1988 to recover the endangered fishes while water development proceeds in accordance with federal and state laws and interstate compacts.

    From The Summit Daily News (Kevin Fixler):

    Through both natural and man-made activities, the area’s waterbodies will ramp back up to seasonal heights this week. The National Oceanic and Atmospheric Administration anticipates the Colorado River and its primary Summit County tributaries will reach their highest 2017 levels this Wednesday, June 7.

    The volume-based flow rates, measured as cubic feet per second, on North Tenmile Creek, for example, will rise from about 600 to 900 cfs and the Blue River north of Dillon should grow in the next two days by another couple hundred cfs from its present 600. To offset forthcoming supply, Denver Water, which owns and oversees Dillon Reservoir, stated that it plans to up flows from Dillon Dam into the Lower Blue River from its Monday total of 380 cfs to 600 no later than Tuesday morning, and between 1,400 and 1,800 cfs by the end of the week.

    “The snowpack up on the mountain, it’s now warmed up and is starting to come off,” said Jim Pokrandt, spokesman for the Colorado River District, a public policy agency that closely monitors the region’s major waterway. “It’s fast water, but shouldn’t flood anybody out. All streams will be quicker-paced than people are used to, but the flooding is not the danger.”

    […]

    North of Silverthorne, additional releases at Green Mountain Reservoir also allow the Bureau of Reclamation to increase power plant capacity and generate more electricity. Those levels could reach approaching 1,400 cfs from the current 418.

    Estimating that 40 percent of the winter’s snowpack still remains above Dillon, Denver Water is comfortable increasing the flows from Dillon Reservoir into the Lower Blue River that ultimately head to northern Arizona’s Lake Powell. That result is threefold, preventing wasteful overflow of the reservoir, maintaining ideal recreational heights on the lake, as well as fulfilling the demands of Lower Basin states based on senior water rights.

    “Our experts are monitoring conditions carefully with the goal of ending runoff season with a full reservoir,” Matt Wittern, Denver Water Summit County liaison, wrote by email. “That way, we’re able to meet our customers’ needs while providing locals and tourists alike with valued summer recreation activities that have a positive impact on the local economy.”

    From The Mountain Town News (Allen Best):

    Where spring runoff has been something like average—and where it hasn’t

    Spring runoff of the Yampa River likely peaked on May 14 this year as it flowed through northwestern Colorado. That makes it an anomaly in the precipitation-dripping mountains of the West.

    In most other locations, the peak runoff—the time when the largest volume of water in rivers occurs as winter’s snow melts—more normally occurs in early June after temperatures finally warmed. This year looks to be more or less normal, despite a trend to earlier runoff in many locations during the last several decades.

    “The Yampa did have an early runoff, and that was the result of the warm temperatures and below-average snowpack,” said Ashley Nielson, senior hydrologist with the Colorado Basin River Forecast Center in Salt Lake City, when interviewed last week by Mountain Town News. The Yampa, she noted, will probably rise again in the next week or so, if not to the same high mark.

    But elsewhere, the show is now, not a month ago. Peak runoff of the Green River was expected this week or next. It originates in the Wind River Range of west-central Wyoming. Unlike the Yampa, that basin still has a significant snowpack. That was also reported to be the case in Jackson Hole, at the headwaters of the Snake River. The snowpack there was 181 percent of average in late May, not a record but “up there,” in the words of one water official cited by the Jackson Hole News&Guide.

    Peak runoff in the upper Colorado River at its headwaters along the Continental Divide in Colorado was also expected to occur in early June.

    Winter had wild swings: barren until late fall, then torrents of snow in December and January. Temperatures were unseasonably warm in February and almost hot in March. It looked like an early runoff everywhere. Then May turned cold and snowy.

    What explains the Yampa’s aberrant behavior? Karl Wetlaufer, a hydrologist with the Natural Resources Conservation Service in Denver, said the peak snowpack in northwestern Colorado arrived about a month earlier than usual. That snowpack around Steamboat Springs occurred on March 12, compared a more typical April 10.

    Instead of mid-May for the Yampa, he says that rafters floating through Dinosaur National Monument more often experience the highest water flows of the year in early June.

    Flows in the Animas River through Silverton and Durango have had some “pretty wild swings,” Wetlaufer says. The Arkansas River has been slow to get started with runoff.

    The Snake River of Wyoming and Idaho has a very different story than the Yampa, with around 200 percent of snowpack this year. The Snake originates in Jackson Hole and picks up water from the Big Wood River, which originates in the Sawtooth Mountains above Ketchum and Sun Valley, before joining the Columbia at the Idaho-Washington border.

    “My takeaway is that this year is pretty normal” in terms of timing, says Bruce Anderson, the senior hydrologist at the Northwest River Forecast Center, in Portland, Ore. It was cooler and wetter in spring, but the big story was the amount of precipitation that fell during winter. “We are hugely above normal for precipitation.”

    In the Tahoe-Truckee area of California’s Sierra Nevada, the snowpack was among the deeper ones on record after three bad drought years and then a so-so winter in 2015-16. Snowfall this winter was not a record, but it was a record for total precipitation. Being somewhat lower and closer to the coast than Colorado, the Sierra Nevada gets more rain during winter. This year it got a lot of rain.

    Colorado, too, had rain on snow, which is not unprecedented. But it happened frequently this winter. The result was telling for travelers on I-70 who crossing Vail Pass.

    “In general, there was less snow than you would expect,” says Klaus Wolter, a research scientist at the National Oceanic and Atmospheric Administration in Boulder.

    Were those rain on snow storms of this past winter a result of accumulating greenhouse gas emissions? Wolter told Mountain Town News that thinks this is “probably partially climate change.”

    Wolter, whose focus is empirical climate research, using statistical methods to solve climate problems, is reluctant to pin climate change on much of what we have seen this year. True, he says, one storm during May left 42 inches of fresh snow in the foothills above Boulder, a storm unprecedented since the 1920s. As extreme as that storm was, proving causality is difficult, he says.

    A scientist in Oregon also shared the difficulty of proving causality. John Stevenson of Oregon State University told the Idaho Mountain Express in Ketchum that it’s “really difficult to judge any one year” to be a result of rising global temperatures.

    “That’s one of the challenges we run into in the science world where people say, ‘Oh, it’s climate change.’ We’re not at the point where we can take any one random event and say it’s climate change.”

    That said, his 2015 study concluded that the point each spring when half of the water year’s streamflow had run off was occurring an average 1.9 days earlier per decade.

    But more extreme events are happening with greater frequency, said Mark Davidson, director of conservation initiatives with The Nature Conservancy. He pointed out that the Big Wood River has had two 100-year floods in the last 15 years.

    Warm temperatures in the Ketchum and Sun Valley area were 6 to 13 degrees warmer than normal for early May, producing a flood in the Big Wood River that peaked on May 8. It was regarded as the largest in 101 years of recorded history, reports the Idaho Mountain Express.

    But more warm weather was producing another surge in early June that threatened to surpass that peak of a month before, the newspaper reported last week.

    CPW puts a $20 bounty on Northern Pike at Green Mountain Reservoir

    Here’s the release from Colorado Parks and Wildlife:

    A cash-based incentive offered by Colorado Parks and Wildlife and the Colorado Water Conservation Board encouraging anglers to catch northern pike at Green Mountain Reservoir resumes this year on May 25. Initiated in 2016, the reward program encourages anglers to participate directly in ongoing efforts to remove the illegally introduced predators from the reservoir.

    CPW biologists say the presence of the predatory fish in Green Mountain is a significant concern. In addition to the potential impacts to fish in the reservoir, if they escape and take up residency downstream in Gold Medal sections of the Blue and Colorado rivers, sportfishing opportunities for trout could see negative consequences. If the predatory fish eventually reach federally listed critical habitat in the Colorado River, they would prey upon the state’s endangered native fishes – the Colorado pikeminnow, humpback chub, razorback sucker and bonytail.

    “Northern pike are aggressive predators with big appetites and if their population continues to grow in Green Mountain Reservoir, that will likely have profound impacts to local fisheries in the future,” said CPW’s Jon Ewert, aquatic biologist from Hot Sulphur Springs. “This is beneficial in several ways. Anglers can catch a predatory fish and earn some money, it helps us protect fishing here, and helps with our native fish recovery efforts as well.

    According to the Upper Colorado River Endangered Fish Recovery Program, the presence of predators like northern pike and smallmouth bass in native fish critical habitat significantly increases the difficulty of delisting the endangered fishes.

    “We all have an interest in making sure our waters are managed appropriately and we encourage the angling public to stay involved,” said Ewert. “We had excellent response last year, and we expect anglers will be eager to take advantage of this opportunity again this year.”

    To participate, anglers must bring their northern pike to the Heeney Marina along with their driver’s license and fishing license.

    CPW will keep fish heads for analysis, returning the body of the fish to the anglers. Anglers not wishing to keep northern pike can donate their catch to the Marina for later distribution.

    Anglers are encouraged to catch and keep as many smallmouth bass and northern pike as they desire, unless special regulations are in effect on specific waters.

    For more information, contact CPW’s Hot Sulphur Springs office at 970-725-6200, or Heeney Marina at 970-724-9441

    To report illicit stocking or any other illegal wildlife activity anonymously, anglers can call Operation Game Thief at 877-265-6648.

    Whither the invasive mussel prevention at Green Mountain Reservoir?

    Green Mountain Dam via the Bureau of Reclamation

    From the Summit Daily News (Kevin Fixler):

    It may still be peak ski season, but the time for boating is right around the corner and local officials are at a loss for how to keep up an invasive species prevention program at Green Mountain Reservoir with funding reserves currently bone dry…

    Green Mountain, located on the northern end of the county along the Blue River, is considered a relatively high-priority site because of its proximity to the Front Range, and, as a result, large volumes of boaters. It’s why Summit County administrators are ramping up efforts to find financial resources and maintain area boat inspections on the U.S. Bureau of Reclamation-owned reservoir and curb these critters’ arrival…

    Green Mountain is much smaller scale, with annual inspection costs that run upwards of $80,000. From 2009-14, the U.S. Forest Service fully funded these watercraft review and decontamination measures based out of the Heeney Marina, but the federal agency was forced to eliminate the program in 2015 due to slashed budgets. Colorado Parks and Wildlife stepped up and paid for the aquatic nuisance species prevention efforts in 2015 and 2016, but recently ran into diminished allocations as well and had to pull out of Summit and focus reserves on only extremely high-risk CPW waters this upcoming summer…

    For its part, the Bureau of Reclamation acknowledges awareness of this growing problem, but does not itself conduct or organize recreation or related facilities on the bodies of water it possesses. Instead, it merely authorizes approved activities as managed by partner agencies, such as Larimer County at both Horsetooth Reservoir and Carter Lake in Northern Colorado, and therefore expects those entities to cover these associated costs.

    CPW still intends to provide training to staff at Green Mountain’s Heeney Marina in 2017, and do its best to assist with monitoring at a reduced rate. The state agency is also presently in discussions with the Forest Service, as well as other organizations, to see what amount of collaboration might be possible to continue the nuisance species prevention programming in future years.

    Meanwhile, at a governmental level, the idea of a bill this legislative cycle requiring a permit in the form of a vessel sticker, say, at a cost of $5 per kayak and $25 per larger boat, has been floated. But as of yet, no one in the General Assembly has stepped up to sponsor such a proposal, even as summer fast approaches.

    Green Mountain Reservoir operations update: 700 cfs in the Blue River below the dam

    From email from Reclamation (Peter Soeth):

    Green Mountain Reservoir continues to release 700 cfs to the Blue River to meet water delivery obligations. It is expected to continue for at least the next couple of weeks. Green Mountain Reservoir release includes storage water to support the Colorado River Endangered Fish Recovery Program, contract obligations and replacement water for the Colorado River Collection System.
