Green Mountain Reservoir operations update: 365 cfs in the Blue River below the dam

coloradobigthompsonmap.jpg

From email from Reclamation (Kara Lamb):

At about 7 this morning, July 25, we cut back releases to around 365 cfs. The flow in the lower Blue River below Green Mountain Dam will remain at 365 cfs until the next change.

There has been some recent rain in the upper Colorado River Basin and the river’s flows are up slightly. As a result, we cut back on Green Mountain’s contributions to the river system. We, the State, and other reservoir operators will continue responding to Colorado River flows as best we can throughout this water year. So please be aware that there will likely be additional changes.

Green Mountain Reservoir operations update: 540 cfs in the Blue River below the dam

greenmountainreservoir.jpg

From email from Reclamation (Kara Lamb):

After yesterday’s Colorado River coordination call, we made adjustments to the release from Green Mountain Dam to the Lower Blue River. We are now releasing about 540 cfs.

As you all likely are aware, flows in the Colorado River continue to decline. In response, we have bumped our releases up another 50 cfs from 490 to 540 cfs.

The reservoir is currently at a water level elevation of 7920 feet above sea level, about 30 vertical feet down, or roughly 65% full.

It’s likely the 540 cfs will remain in place through the weekend.

Green Mountain Reservoir operations update: 370 cfs in the Blue River below the dam

coloradobigthompsonmap.jpg

From email from Reclamation (Kara Lamb):

We continue to make adjustments to our releases based on the cooperative efforts of the larger water operators’ community on the Upper Colorado River. Currently, we are releasing about 370 cfs from Green Mountain Dam to the Lower Blue River. There could be additional changes over the weekend.

Green Mountain Reservoir operations update: 150 CFS in the Blue River below the dam #CODrought

greenmountainreservoir.jpg

From email from Reclamation (Kara Lamb):

We have begun our weekly coordination calls for reservoir operations across the upper Colorado River basin. Flows in the Colorado River are rapidly declining, as most of you know. As a result, we are upping releases from Green Mountain to the Lower Blue today in two phases. By late this afternoon, we’ll be releasing 150 cfs.

The road across the dam has also reopened as the bridge work is nearly complete.

Glenwood Springs: Council approves the Colorado River Cooperative Agreement

coloradorivercooperativeagreementmap.jpg

From The Aspen Times (John Stroud):

Glenwood Springs City Council voted 5-1 at its Thursday meeting to sign the Colorado River Cooperative Agreement. The vote came more than a month after the proposal was first presented for council’s consideration.

ā€œIt’s unheard of that so many entities are willing to talk about what works for everyone,ā€ Councilman Stephen Bershenyi said, in favor of signing onto the agreement.

Added Mayor Matt Steckler, ā€œIt’s not perfect, but this is something we have been working on for over a year. I don’t see what not signing it is going to do.ā€

Councilman Dave Sturges dissented, saying he supports the efforts to reach an agreement on the use of Colorado River water. But he felt the agreement fell short in some areas and that the public had not had an adequate opportunity to weigh in.[ed. True, the agreement was hammered out under Non-Disclosure agreements amongst the parties.] ā€œWe’re not under the gun to act on this,ā€ Sturges said. ā€œThere are still some questions, and I think the public ought to assist us in how we view those questions.ā€

The Denver Post editorial board weighs in on the Colorado River Cooperative Agreement

coloradorivergranby.jpg

From The Denver Post:

One of the linchpins is that Denver Water, which serves more than 1.3 million customers on the Front Range, gets approval for the expansion of Gross Reservoir near Boulder. The utility needs the project so it may ensure adequate water for customers on the northern edge of its service area…

The agreement calls for Western Slope parties to not oppose ā€” and in some cases support ā€” the Moffat Collection System project, which includes the reservoir expansion.

Green Mountain Reservoir operations update: 75 cfs in the Lower Blue River below the dam

greenmountainreservoir.jpg

From email from Reclamation (Kara Lamb):

This morning, we had a slight change in releases from Green Mountain Dam to the Lower Blue River. To meet a call for water, we bumped releases up by 15 cfs. That means there is now approximately 75 cfs in the Lower Blue below the dam.

Meanwhile, the road across Green Mountain Dam is still closed as we upgrade the bridge. Access below the dam and to the Town of Heeney is open by driving around the reservoir from the south.

Green Mountain Reservoir operations update: 60 cfs in the Blue River below the dam

greenmountainreservoir.jpg

From email from Reclamation (Kara Lamb):

We have a couple of changes up at Green Mountain Dam.

First, yesterday, April 18, we closed the road across the dam. We are in the process of replacing the bridge at the top of the dam. It is being brought up to current Department of Transportation codes. This section of the road will be closed through mid-May.

It is important to note that , despite the road closure, local business in Heeney are still open and can be reached by driving around the reservoir the other way (coming from the south). This is also the only way to access the road that drops down alongside Green Mountain Dam for fishing and kayaking access in the lower Blue River.

Second, we scaled releases from the dam to the Lower Blue back by about 15 cfs today. Some demands for water dropped off slightly, resulting in a lower release rate. We are now releasing about 60 cfs from Green Mountain Dam to the Lower Blue.

Summit County ‘State of the River’ meeting scheduled for May 8

coloradoriverbasincgs.jpg

From the Colorado Division of Water Resources via the Summit Daily News:

Jointly sponsored by the Colorado River District and the Blue River Watershed Group, the evening begins with water administration and project updates for the BLue River Basin, followed by a discussion of current snowpack and runoff predictions.

Bob Steger from Denver Water and Ron Thomasson from the Bureau of Reclamation will report on Dillon and Green Mountain Reservoir operations and how those operations will affect water-based recreation opportunities.

Summit County manager Gary Martinez will provide an update on the Colorado River Cooperative Agreement, while George Sibley commemorates the 75th anniversary of the Colorado River District with an historical perspective of the District, as well as Summit County’s water struggles and achievements over the years.

Scott Hummer, now the project manager for the Colorado Water TRust, will discuss the organization and its mission to protect and restore streamflows throughout Colorado.

The Blue River Watershed Group will highlight developments with collaborative restoration efforts. It will also be a chance to shake hands with Summit County’s new water commissioner, Troy Wineland.

Green Mountain Reservoir operations update: 125 cfs in the Blue River below the dam

greenmountainreservoir.jpg

From email from Reclamation (Kara Lamb):

We made another change at Green Mountain Reservoir earlier today [March 27]. As we continue to prepare for some upcoming maintenance, we scaled releases from the dam to the Lower Blue back another 50 cfs. The Lower Blue is now running at about 125 cfs.

Colorado River Cooperative Agreement outstanding issues: Operating the Shoshone power plant and Green Mountain Reservoir

coloradorivercooperativeagreementmap.jpg

From the Grand Junction Daily Sentinel (Gary Harmon):

Two major issues, the administration of Green Mountain Reservoir and the Shoshone power plant in Glenwood Canyon, remain to be resolved. They are the same issues that parties acknowledged early on would be difficult but not insoluble. ā€œItā€™s painfully slow,ā€ Colorado River District General Manager Eric Kuhn said, ā€œbut weā€™re making a lot of progress.ā€[…]

The two issues closest to the Western Slope are joined, with the Green Mountain question needing to be dealt with first, Kuhn said. Agreement on the administration of Green Mountain Reservoir, which was built as part of the Colorado-Big Thompson Project, ā€œfundamentally sets the stage for moving ahead on Shoshone,ā€ Kuhn said. ā€œA lot of issues have arisen over the years on Green Mountain Reservoirā€ that boil down to making sure the reservoir fills and that the demands of Denver Water and Colorado Springs are met, said Mark Hermundstad, a Grand Junction water attorney who represents several Grand Valley water users…

Colorado River water spins turbines in the Shoshone plant, and downstream users have long counted on Shoshoneā€™s call on the river to make sure water is sent downstream through the Grand Valley rather than diverted eastward. There is a rub, though, and it concerns the times that Shoshoneā€™s turbines are idle and the plant, therefore, is not drawing its 1,250 cubic feet per second of water from the river. The short-term answer is what has become known as the Shoshone outage protocol, in which upstream diverters agree to allow the river to flow as though Shoshone were operating. Part of that formula, however, depends on how Green Mountain Reservoir, which is owned by the U.S. Bureau of Reclamation, is managed.

Low numbers for aquatic life prompts the CWQCD to designate the Blue River for monitoring and evaluation

blueriver.jpg

Here’s a report from Bob Berwyn writing for the Summit County Citizens Voice. Click through and read the whole article. Here’s an excerpt:

The sampling results prompted the Colorado Water Quality Control Division to propose listing the Blue River as impaired under a relatively new rule that sets thresholds for aquatic life use…

Water experts from Summit County and other jurisdictions challenged the initial move to list the Blue River and other stream segments as impaired, claiming that the state-set thresholds ā€” adopted after 10 years of study ā€” may not be applicable in rivers below reservoirs.

For example, Aurora officials questioned whether or not the data collected below a dam should be evaluated as being representative of an entire stream segment. They suggested that changes in natural temperature alterations, low dissolved oxygen, sediment, nutrient composition and hydraulic modifications may alter the biological community below reservoirs.

Green Mountain Reservoir operations update: 300 cfs in the Blue River below the dam

greenmountainreservoir.jpg

From email from Reclamation (Kara Lamb):

Earlier this week, we increased the releases from Green Mountain from 200 cfs to 300 cfs. The change was made in four installments of 25 cfs increases: two on Monday and two on Tuesday. Because the Shoshone Power Plant maintenance work is diminished, the lower release from Green Mountain is not necessary. As a result, we will be releasing around 300 cfs through the Holidays.

Windy Gap Firming: Recently released final EIS acknowledges potential declines in streamflow in the Upper Colorado River basin

windygapmoffatfirmingboulderviewpoint.jpg

From the Summit County Citizens Voice (Bob Berwyn):

Even more worrisome to conservation advocates are the projected declines in summer flows. Below Windy Gap Reservoir, July flows could drip by as much as 20 percent, according to the Bureauā€™s study, which also acknowledged that extensive mitigation measures will be needed to protect West Slope aquatic ecoystems…

But the proposed mitigation falls short of whatā€™s needed to protect the Upper Colorado, according to Trout Unlimited, a cold-water fisheries conservation group.

Here’s the release from Colorado Trout Unlimited (Randy Scholfield):

A new federal report on the environmental impacts of a plan to expand the Windy Gap water diversion project in Colorado falls short of recommending whatā€™s needed to protect the fragile Upper Colorado River, according to Trout Unlimited.

The Final Environmental Impact Statement, released by the U.S. Bureau of Reclamation on Nov. 30, outlines the anticipated effects of the proposed project and recommends needed mitigation.

ā€œThis new document is an improvement over the previous version in that it acknowledges the Windy Gap project will worsen conditions in the Upper Colorado River and Grand Lake unless measures are taken,ā€ said Drew Peternell, executive director of Trout Unlimitedā€™s Colorado Water Project. However, the mitigation proposed by the bureau falls far short of what is needed and critical problems continue to be ignored. We urge the Bureau to require additional protective measures to preserve this irreplaceable natural resource.ā€

ā€œTrout Unlimitedā€™s concerns with the Environmental Impact Statement are echoed by the Upper Colorado River Alliance, a nonprofit group that is also seeking to require more mitigation to protect the river,ā€ said Boulder attorney Steven J. Bushong, a representative of the Alliance.

The report comes out as Trout Unlimited is launching a petition campaign to protect the Upper Colorado River and its tributary, the Fraser River, and the mountain communities, businesses, people and wildlife that depend on them. The petition campaign, based online at DefendTheColorado.org, is being spearheaded by Trout Unlimited to engage advocates for the iconic but threatened rivers. The website allows advocates to sign on to a petition that will be delivered to decision makers before the bureau makes a final decision on the Windy Gap project. That decision is expected in early January.

ā€œThe good news is that the Bureau of Reclamationā€™s Environmental Impact Statement says additional mitigation measures may be added before the agency makes a final decision. That highlights the importance of taking action to stand up for the river now,ā€ Peternell said.

Already 60 percent of the Upper Colorado is diverted to supply Front Range water users. The Windy Gap proposal, along with a separate Moffat Tunnel water project, could divert as much as 80 percent of the Upper Coloradoā€™s natural flows. According to Trout Unlimited, steps must be taken to protect the rivers including:

Ā· Managing the water supply to keep the rivers cool, clear and healthy.
Ā· Funding to deepen river channels and create streamside shade.
Ā· Monitoring of the riversā€™ health and a commitment to take action if needed to protect them.
Ā· Bypassing the Windy Gap dam to reconnect Colorado River and restore river quality.

ā€œThe Final Environmental Impact Statement continues to ignore existing problems that will be made much worse by the Windy Gap project,ā€ said Sinjin Eberle, president of Colorado Trout Unlimited. ā€œA study released by the Colorado Division of Parks and Wildlife earlier this year shows that entire populations of native fish and the insects they feed on have all but disappeared from the Colorado River below the Windy Gap Reservoir. The state study blames the reservoir and the lack of spring flows that clean sediments from the stream beds and warns that expansion of the Windy Gap project poses additional threats to the health of the river and the aquatic life in it.ā€ See http://www.cdphe.state.co.us/op/wqcc/Hearings/Rulemaking/93/Responsive/93rphsTUexG.pdf

The Windy Gap project also impacts the health of Grand Lake. “Grand Lake – once a pristine lake of dramatic clarity and scenic beauty – has become cloudy, weedy and silty because of diversion water pumped into the lake from Shadow Mountain reservoir,” said John Stahl of the Greater Grand Lake Shoreline Association. “Nothing in the FEIS mitigation plan is helpful in addressing the existing problems–at best it maintains the status quo while more likely creating even bigger problems.ā€

The Environmental Impact Statement indicates that the Bureau of Reclamation will monitor to ensure that mitigation is adequate and will impose additional measures if necessary. ā€œThatā€™s helpful but needs to be more clearly articulated. Another critical addition is the construction of a bypass around the Windy Gap dam,ā€ Eberle added.

The DefendTheColorado.org campaign highlights the people who depend on the rivers.

ā€œThe Colorado and Fraser rivers arenā€™t just bodies of water, they are the lifeblood for wildlife, local communities and the stateā€™s recreation economy,ā€ Eberle said. ā€œBut many Coloradans are unaware that these rivers are on the brink of collapse because of diversions. DefendTheColorado.orgā€™s purpose is twofold ā€“ to raise awareness about the threats facing the Colorado and Fraser and to give people a way to stand up for our rivers.ā€

Eberle added, ā€œWe canā€™t afford to let these rivers literally go down the drain.ā€

A new feature of the website called ā€œVoices of the Fraserā€ profiles local Fraser Valley residents and visitors who speak eloquently about their connection to the Fraser River and the need to preserve healthy flows. Among the individuals profiled are Olympic skier Liz McIntyre, logger Hoppe Southway and landscape artist Karen Vance.

ā€œIt would be a shame to see any of these tributaries dry up just for the sake of developing the Front Range,ā€ said Southway in his profile. ā€œItā€™s the water my children and grandchildren are going to want to see someday, and I hope itā€™s protected for future generations.ā€

Visitors to the site also have added their voices about why the river is important to them.

ā€œI have fished and hiked the Fraser and Upper Colorado river regions for over 30 years and am deeply saddened by the degradation of these great watersheds,ā€ a Golden, Colo., resident wrote.

A Bonita Springs, Florida, resident wrote: ā€œI LOVE fishing that stretch of water and find such a simple peace of being in that area. Please don’t mess with such a special place.ā€

ā€œAs a visitor and fisherman to Colorado on a regular basis, my tourist dollars help the local communities,ā€ noted a resident of Blue Springs, Missouri.

Reflections on the Colorado-Big Thompson Project — W.D. Farr

wdfarrcoloradobigthompsonprojectgreeleywater.jpg

Here’s a video with W.D. Farr explaining the origins of the Colorado-Big Thompson Project. Thanks to Greeley Water for posting the video.

Next year is the 75th anniversary of the 1937 act that established the water conservancy districts and the Colorado Water Conservation Board.

Farr explains that Congressman Taylor would not support the project unless Green Mountain Reservoir — for west slope supplies — was built first.

“The biggest cloud of dust I ever saw came out of that tunnel [Adams Tunnel],” Farr says, “I never saw men so happy in my life.”

DefendTheColorado.org website launches to build awareness of upper Colorado River basin streamflow issues

denverwatercollectionsystemmap.jpg

Say hello to DefendTheColorado.org, a new website designed to connect interested people and raise awareness of the issues around transbasin diversions from the Upper Colorado River here in Colorado. Here’s a report from Tonya Bina writing for the Sky-Hi Daily News. From the article:

For the Trout Unlimted Project, [Editorial Photographer and Videographer Ted Wood of Story Group, Boulder] brought in Boulder colleagues Beth Wald, a photojournalist who of late has been covering environmental and cultural stories in Afghanistan, and Mark Conlin, a seasoned underwater photographer.

ā€œWe launched the project as a way to get more visibility of the stream-flow issues on the Fraser and Upper Colorado,ā€ said Trout Unlimited’s Randy Schoefield. ā€œWhat we’re trying to portray is the community’s deep connection to the river.ā€

The Story Group plans to add more portraits to the website in coming days and weeks. Eventually, Trout Unlimited hopes to host public events that display the portraits as well as work by other photographers, granting a full sense of the river’s significance in Grand County and the consequences of further transbasin diversions.

Green Mountain Reservoir operations update: Reclamation is cutting back releases to 600 cfs in the Lower Blue River by Saturday night

greenmountainreservoir.jpg

From email from Reclamation (Kara Lamb):

This morning (October 28), we began curtailing releases from Green Mountain Dam to the Lower Blue River. We are stepping releases down in 50 cfs increments. At 8 a.m., we dropped from 800 to 750 cfs. This evening around 8 p.m., we will drop another 50 from 750 to 700 cfs. We will follow a similar pattern on Saturday. By Saturday evening, releases from Green Mountain Dam will be around 600 cfs. It is likely the reductions could continue to drop during the first week of November. I will keep you posted of future changes.

Green Mountain Reservoir operations update: 750 cfs in the Lower Blue River below the dam

greenmountainreservoir.jpg

From email from Reclamation (Kara Lamb):

If you’ve been out on the Lower Blue this morning [ed. October 12], you probably noticed that it’s running a little lower than yesterday. That is because this morning around 6:30, we dropped releases from Green mountain Dam by about 50 cfs. Currently, there is 850 cfs flowing below the dam. We will be making additional changes today. We will drop again at noon today, by 50 cfs, putting the Lower Blue around 800 cfs. Then around 5 p.m. today, we will drop another 50 cfs. By the end of the day, releases from Green Mountain Dam to the Lower Blue will be around 750 cfs.

The reason for the change is two fold: the 15-Mile Reach of critical habitat for endangered fish no longer needs additional water and the Shoshone Plant has some maintenance work. Reduction in flows will help both projects.

Green Mountain Reservoir operations update: 500 cfs in the Blue River below the dam by Friday

greenmountainreservoir.jpg

From email from Reclamation (Kara Lamb):

After the weekly conference call yesterday, it was determined that releases from Green Mountain would increase. We have been releasing about 400 cfs for some time. The change will put 500 cfs in the lower Blue River. The first change was today a 9 a.m. We bumped up 50 cfs. Currently, 450 is being released to the Lower Blue. Tomorrow, Friday, we will bump up another 50 cfs around 8 a.m. By lunch, there should be 500 cfs in the river. This increase will help provide water to the critical habitat of the endangered fish of the Colorado River.

Implementing the Colorado River Cooperative Agreement hangs on resolving how to operate the Shoshone right and Green Mountain Reservoir

shoshoneglenwoodcanyon.jpg

From the Associated Press via The Columbus Republic:

According to the Grand Junction Daily Sentinel (http://bit.ly/pblJYV ), western Colorado water providers want an agreement on the operation of the Shoshone power generating station in Glenwood Canyon and another on the operations of Green Mountain Reservoir.

Six months ago, officials from the Western Slope and Denver announced they had a general agreement that would resolve most of the issues, but none of the backers have signed an agreement.

Colorado-Big Thompson Project update: Horsetooth Reservoir is as full as it has been since 1999

horsetoothreservoir.jpg

From the Loveland Connection (Bobby Magill):

The surface elevation of Horsetooth Reservoir, which stores water from the Colorado River on the Western Slope, is at 5,419 feet, about 11 feet below full pool of 5,430 feet.

The Colorado-Big Thompson Project, of which Horsetooth Reservoir is a part, set an all-time record for in-flows from the Colorado River, he said. Lake Granby, Shadow Mountain Lake and Grand Lake all received 430,000 acre-feet of water from the Colorado River, more than 75,000 acre-feet more than the previous record of 355,000 acre-feet, he said…

Horsetooth and other area reservoirs are full enough to put water managers in a good position to deliver plenty of water to irrigators next year regardless of how snowy the winter is, [Northern Colorado Water Conservancy District spokesperson Brian Werner] said. We’re in good shape,” he said. “We can get by with average or below average winter snows this year and be fine next year.”

Green Mountain Reservoir operations update: 750 cfs in the Lower Blue River below the dam

greenmountainreservoir.jpg

From email from Reclamation (Kara Lamb):

Today [August 10], we’re dropping releases from Green Mountain Dam to the lower Blue by another 200 cfs. By late this afternoon, flows in the lower Blue should be around 750 cfs. Inflows to Green Mountain Reservoir are dropping off. As we continue to match outflow with inflow, the reservoir water surface elevation is remaining fairly steady at about 2 feet down from full.

Colorado-Big Thompson Project update: Reclamation is moving water from Grand Lake to Shadow Mountain Reservoir to test the effects on Grand Lake clarity

coloradobigthompsonmap.jpg

From email from Reclamation (Kara Lamb):

Even though we finally have the snow melt run-off behind us, we are still releasing water from Granby Dam to the Colorado River. Currently, we are releasing about 500 cubic feet per second. The reservoir is still pretty full, dropping slowly. Today, it is at a water level elevation of 8278 feet above sea level–about two feet below full.

The current release of 500 cfs will continue most likely through September and possibly into October.

The reason for the longer-than-most-years release is two-fold. First, we just have a lot of water this year. The heavy snow pack is still melting out from the highest mountain elevations, albeit much more slowly than in June and July.

Second, and most significantly, with all the snow melt and then the rain we had this summer, there just is not a lot of demand for water from the east slope. Plus, east slope storage is close to full. Without a call for or a place to store C-BT water, we cannot import it from the west to the east slope.

Additionally, this is the time of year we adjust how we run the C-BT west slope system as part of our on-going work to improve clarity in Grand Lake. For the past four years we have experimented with different operations. This year, we are attempting to maintain a steady flow from Grand Lake to Shadow Mountain Reservoir. Usually, the flow is in the opposite direction because we are diverting more water to the east slope.

I have received several questions over the past few days regarding the west slope collection system. Please feel free to contact me directly with any additional questions. More C-BT information is also available by visiting Northern Water on-line, or by visiting Reclamation’s website.

From email from Reclamation (Kara Lamb):

Most of you have probably noticed that Pinewood has not gotten as high this summer as it has in previous years. I’ve had a couple inquiries so I thought it was a good time to send out an e-mail update.

The reason for Pinewood’s elevation fluctuation is because it is a forebay for the Flatiron hydro-electric power plant ; it’s the water storage above a power plant. Water is stored in the reservoir to build up “head,” or energy, then run downhill to produce that energy at the plant below . Because we are only generating with one of the two units and because we have had so much water move through the system this year, Pinewood’s fluctuations this summer have been slightly different than in other summers: it isn’t getting as high as most are used to seeing.

We’re going to try and get the water elevation at Pinewood back up for this weekend, however. Right now, Pinewood’s water surface elevation is on the decline. Its current elevation is about 6567 feet–about 13 feet below full–and it will probably go down another three feet or so. The good news is the decline will stop later today and the reservoir will begin to rise again. The elevation climb will continue well into the coming weekend…

If you’d like more information on the Colorado-Big Thompson Project of which Pinewood is a part, please visit us on-line.

From email from Reclamation (Kara Lamb):

As snow melt run-off has declined in the Blue River basin, we’ve been cutting back our releases from Green Mountain Dam to the lower Blue River. Releases have dropping over the last week.

The most recent change was this morning, calling for another reduction. By early evening, releases from the dam should be around 950 cfs. Additional changes will depend on weather and water demands.

The reservoir elevation has remained very close to full. It is currently at about 7948 feet, two feet down from full.

Colorado-Big Thompson Project update: Granby is releasing about 420 cfs

coloradobigthompsonmap.jpg

Just a quick note to update you all on our facilities across the Colorado-Big Thompson Project. I’ve also updated our webpages. Once on our main page, be sure to check out the menu on the left hand side to see information on our other facilities.

Meanwhile, Granby is releasing about 420 cfs.

Willow Creek is releasing about 77 cfs.

Olympus Dam on Lake Estes is releasing about 125 cfs.

All reservoirs are basically full, with the exception of Lake Estes, Pinewood and Flatiron. These three fluctuate often due to hydro-power generation. Pinewood and Flatiron, in particular, might drop significantly over the course of one day, then rise back up again.

Northern Colorado Water Conservancy District tour attracts nearly 100 taxpayers, city officials, water district employees and students

coloradobigthompsonmap.jpg

From the Carbon Valley Miner and Farmer (Gene Sears):

Nearly 100 participants attended the tour, a mix of taxpayers, city officials, water district employees and students, split between two buses hired by the district for the trip. Starting at NCWCD headquarters in Berthoud, the tour headed northeast up Big Thompson Canyon, through Estes Park and onto Trail Ridge Road in Rocky Mountain National Park, headwaters for much of the districtā€™s supply…

Built at a cost of $162 million, the project began full water deliveries in 1957. As it stands now, the Colorado-Big Thompson system consists of 12 reservoirs, 35 miles of tunnels, 95 miles of canals and 700 miles of power transmission lines. Spanning 150 miles east to west and 65 miles north to south, C-BT provides water to almost 700, 000 irrigated acres and more than 750,000 people in the South Platte River Basin.

Colorado-Big Thompson Project update: Releases from Lake Granby to increase

A picture named granbyspill06222011

From email from Reclamation (Kara Lamb):

Recent rain storms and the tail end of snow melt run-off continue to produce high inflows into Lake Granby. As a result, we and Northern Water have been increasing releases from Granby Dam to the Colorado over the last few days. Today, releases are going up again, by about 300 cfs. We will soon be releasing upwards of 2200 cfs. The reservoir is just about full with only two and a half feet to go. Rain on the East Slope has reduced the need for diversions from the West Slope. As a result, more water must be released at the dam.

From email from Reclamation (Kara Lamb):

Just a quick heads up: late last night/early this morning, releases from Olympus Dam were scaled back by about 100 cfs. We are now releasing around 575 cfs from the dam to the lower Big Thompson River. Even though we have had some higher inflows from the recent storms, we are still capturing priority water (east slope run-off) in the C-BT project and using it to generate hydro-power and top off Horsetooth and Carter reservoirs. As a result, we have cut back diversions from the West Slope through the Adams Tunnel. With the tunnel low and the east slope water being taken through the system, we are able to reduce releases to the canyon a little bit.

Currently, we are releasing about 3300 cfs from the dam to the Lower Blue. The reservoir is about half an inch from completely full.

From email from Reclamation (Kara Lamb):

Just a quick note to say that both Horsetooth and Carter Lake reservoirs are pretty darn full…this is the highest the water elevation has been at Horsetooth since 2004. Currently, it’s at a water level elevation of 5421–and still rising!

From email from Reclamation (Kara Lamb):

As you’ve probably noticed, releases from Olympus Dam to the Big Thompson Canyon have not changed much over the last week. We wound up dropping just less than 100 cfs since my last note.. We are currently releasing about 730 cfs. The forecasted rain storms in the mountains could bring some changes. If we see a rain run-off inflow peak into Lake Estes that is substantial, we could increase releases from Olympus Dam. However, right now we are planning to keep the 730 cfs release in place.

Green Mountain Reservoir operations: 2,800 cfs in the Blue River below the dam

A picture named coloradobigthompsonmap.jpg

From email from Reclamation (Sterling Rech):

The inflow to Green Mountain Reservoir remains elevated, Dillon Reservoirā€™s release rate is being increased, and rain continues to be in the forecast. In order to slow the rate at which the reservoir is filling, the Green Mountain Reservoir release will be increased by 300 cfs today. This release rate increase will be accomplished in two steps of approximately 150 cfs each. Because the powerplant is currently running at maximum capacity, these release rate increases will be accomplished by raising the spillway gates. With the current release rate being approximately 2,500 cfs, these release rate increases will result in a flow rate of approximately 2,800 cfs at the Blue River gage below the dam by this afternoon.

Green Mountain Reservoir

Wednesday, July 6, 2011, 1300 hours ā€“ Increase the reservoir release from 2,500 cfs to 2,650 cfs (accomplished by raising all three spillway gates).

Wednesday, July 6, 2011, 1500 hours ā€“ Increase the reservoir release from 2,650 cfs to 2,800 cfs (accomplished by raising all three spillway gates).

Maintain the 2,800 cfs reservoir release until further notice.

Colorado-Big Thompson Project update: 1,800 cfs in the Blue River below Green Mountain Dam

A picture named greenmountainreservoir.jpg

From email from Reclamation (Kara Lamb):

Tomorrow, Thursday June 30, we will be increasing the releases from Green Mountain Dam to the Lower Blue River. We will be bumping up to 1800 cfs. This change will be made in two stages; the first increase of about 150 cfs will be in the morning. The second increase of another 150 cfs will be in the afternoon. The 1800 cfs release will most likely be in place through the 4th of July holiday weekend.

From email from Reclamation (Kara Lamb):

With the high temperatures the last few days, nightly inflows to Lake Estes have been up and down. Peaks to Lake Estes continue to fluctuate between 900-1300 cfs. As a result, we are adjusting the release from Olympus Dam to the Big Thompson Canyon about every other day. Late tonight, June 29, releases to the canyon will jump up from 650 cfs to 790 cfs.

Green Mountain Reservoir operations update: 1,500 cfs in the Blue River below the dam

A picture named coloradobigthompsonmap.jpg

From email from Reclamation (Kara Lamb):

After a brief maintenance stint on one of the hydro-electric generating units at Green Mountain Power Plant, releases from the dam to the Lower Blue River are back on the rise.

Starting this morning at 11 a.m. (June 22), we increased releases from 750 cfs to 900. Later this evening around 8 p.m., we will increase again to about 1100 cfs.

Shortly after midnight tonight, we will bump up to 1300 cfs. And tomorrow morning (June 23) around 5 a.m., we will increase one more time to 1500 cfs.

The 1500 cfs release rate will stay in place until further notice.

Meanwhile, the reservoir is filling pretty steadily at about a foot a day. We’ve got a lot of melting snow pack to still pass on downstream, but are storing what we can, balancing inflows, outflows, and the various demands served by the reservoir.

Green Mountain Reservoir operations update: 750 cfs in the Blue River below the dam

A picture named greenmountainreservoir.jpg

From email from Reclamation (Kara Lamb):

Starting today [June 19], we’ll be doing a little work on one of the hydro-electric generating units at the Green Mountain Power Plant on Green Mountain Dam. As a result, releases from the dam to the Lower Blue began cutting back late last night/early this morning. By early afternoon today (June 19) we anticipate having releases down to around 750 cubic feet per second.

Releases are scaling back in 100 cfs increments. The first change was at 10 p.m. last night, then 1 a.m. this morning, and again this morning at 6 a.m. Early this afternoon, when the unit is removed from service for maintenance, we will drop the last 100 cfs. That last change will leave about 750 cfs going through the other generating unit and flowing down the Lower Blue.

Right now, we are estimating the work will complete by Wednesday. Once the unit is returned to service, we will start ramping releases up again. However, with new snow in the mountains lately, we are not yet sure how high the releases will go later this week. I will update you once we have a better idea.

As for the reservoir, it is currently at a water level elevation of 7930 feet. That’s about 20 feet down from full. The reservoir has been filling pretty steadily for the last two weeks. It has gone up half a foot since midnight.

Green Mountain Reservoir operations: Second power plant back online, 1200 cfs in the Blue River below the dam

A picture named greenmountainreservoir.jpg

From email from Reclamation (Kara Lamb):

Late this afternoon [June 8], the crew at Green Mountain power plant returned the second generating unit back to service. We are now ramping up to generate hydro-electric power at full capacity. As a result, releases through the plant from the reservoir are going up in 100 cfs increments. At 4 p.m. today we bumped up to about 900 cfs. At 6 p.m. we bumped up to around 1000 cfs. We will bump up again at 8 p.m. to 1100 cfs. And we will increase one more time around 10 p.m. tonight to 1200 cfs. We will maintain the 1200 cfs from Green Mountain Reservoir and Power Plant to the Lower Blue River until further notice.

Green Mountain Reservoir update: 1200 cfs in the Blue River below the dam

A picture named greenmountainreservoir.jpg

From email from Reclamation (Kara Lamb):

This morning, May 24, at 8 a.m., we began increasing releases from Green Mountain Reservoir to the Lower Blue. We increased by 100 cfs making the Lower Blue flow around 1100 cfs. This afternoon, we will bump up another 100 cfs putting 1200 cfs in the river.

The reason for the change is the continuing snow accumulation in the high country upstream of the reservoir. We are near record levels for snowpack and the run-off forecast from the Colorado River Basin center continues to go up. We are doing our best to balance inflows, storage and releases with the competing demands served by the reservoir.

Even with this change in releases, the reservoir storage is still increasing. Currently, it is rising at just about a foot a day.

Colorado River Cooperative Agreement: Prior appropriation often conflicts with maintaining streamflow

A picture named coloradorivercooperativeagreementmap.jpg

From The Pueblo Chieftain (Chris Woodka):

ā€œA change to a water right has become a suicide mission and hamstrings these types of agreements,ā€ [Eric Kuhn, executive director of the Colorado River Conservation District] said at last weekā€™s Interbasin Compact Committee. His comments brought a chorus of agreement, and talk of how to implement flexibility and creativity in water rights among others around the table.

Actually, the state has spent months talking with the negotiators about the kinds of things that might be acceptable in guaranteeing flows, State Engineer Dick Wolfe said this week. ā€œWeā€™ve looked at the agreement in order to talk about implementation,ā€ Wolfe said. ā€œWe went through a process to identify flexibility in existing laws.ā€[…]

There are five separate agreements with state and federal agencies that have to be reached in order to implement the Colorado River Cooperative Agreement. State provisions include a Blue River consent decree from Division 5 Water Court in Summit County, agreement on delivery of consumptive flows from Denver in Grand County, and an agreement on environmental flows. Agreements with the Bureau of Reclamation must be reach on the Shoshone power plant and for Green Mountain Reservoir operations…

ā€œWe push to have them take it to water court,ā€ Wolfe said. ā€œIt minimizes what a future state engineer or division engineer may decide.ā€ While court decrees are paramount, the state engineer can administer contracts between water users, and can also shepherd state in-stream flow rights (which can only be held by the Colorado Water Conservation Board) to meet flow demands. Water court case filings serve to notify other water users if changes are being contemplated.

Green Mountain Reservoir operations update: 1200 cfs in the lower Blue River by the weekend

A picture named greenmountainreservoir.jpg

From email from Reclamation (Kara Lamb):

[May 5] we’ll start ramping up releases again from Green Mountain Dam to the Lower Blue. This time, we’re ramping in 100 cfs increments. The first change will be at 8:00 a.m. tomorrow, May 5. That will put us at 900 cfs. Tomorrow afternoon around 6 p.m., we’ll go up another 100, putting 1000 down the Lower Blue. Two similar changes will happen at those same times on Friday, May 6. This means by the weekend, we will be releasing 1200 cfs to the Lower Blue. We’re trying to make room in the reservoir for snow melt. At this time, the reservoir elevation still remains fairly low.

Green Mountain Reservoir Operations update: 800cfs in the Blue River by Sunday night

A picture named greenmountainreservoir.jpg

From email from Reclamation (Kara Lamb):

The DOW will conclude their fish-shocking work in Gore Canyon tomorrow, April 29. As a result, we will start ramping Green Mountain releases back up tomorrow morning at 8 a.m. Increases will be made in 50 cfs increments, twice a day, through the weekend.

The schedule will be the same as before. Changes will be made at 8 a.m. and 8 p.m. Friday, Saturday and Sunday.

Currently, releases from the dam are about 500 cfs.They will go to 600 cfs Friday, 700 cfs Saturday, and level out around 800 cfs by Sunday evening.

We will be in Frisco presenting run-off information on Tuesday, May 3. We are participating in the River District’s annual State of the River meeting for the Blue River. Learn more about this meeting at http://www.crwcd.org/page_115.

Green Mountain Reservoir operations update: 500 cfs in the lower Blue River for the next week

A picture named greenmountainreservoir.jpg

From email from Reclamation (Kara Lamb)

…April 23, we will begin scaling back releases for a fish shocking program the Division of Wildlife will be conducting Monday through Friday next week in Gore Canyon on the Colorado River. As a result, we will reduce releases from 700 cfs to 500 cfs over a period of two days. Reductions will be in 50 cfs increments, twice a day this Saturday and Sunday. A change will be made both mornings at 8 a.m. and again both evenings at 8 p.m. By Sunday evening, flows in the Lower Blue should be around 500 cfs. We will maintain the 500 cfs release through the week, likely ramping up again next Friday or Saturday.

Green Mountain Reservoir operations update: Reclamation to ramp up releases to 500 cfs by Friday

A picture named greenmountainreservoir.jpg

From email from Reclamation (Kara Lamb):

We’ve recently received the April 1 forecast and April is looking to have a little higher run-off than what the March 1 forecast showed. As a result both we and Denver Water will be upping releases over the next few days to balance reservoir storage with anticipated inflow. At Green Mountain Reservoir, we’ll be ramping up in increments of 50 cfs over the next four days, starting…April 5…

That means by Friday afternoon, releases from Green Mountain to the Lower Blue will be 500 cfs. I anticipate that level will stay through this coming weekend, but keep an eye on the gage, just to be sure. With these releases in anticipation of run-off, we’ve been maintaining a surface water elevation of about 7895 in Green Mountain Reservoir. That’s approximately 55 feet down from full–a difference in water level elevation we’re fairly certain to make up during run off.

Green Mountain Reservoir operations update

A picture named blueriver.jpg

From email from Reclamation (Kara Lamb):

Tomorrow morning at 8, Friday March 11, we will increase releases from Green Mountain Dam to the Lower Blue River by 25 cfs. By noon, the Lower Blue should be flowing at about 300 cfs. The reason for the change is Denver Water will be increasing their releases from Dillon Reservoir to the Blue River. Because releases from Dillon Dam flow straight to Green Mountain, we are accommodating the additional water by increasing our own release.

Colorado River basin: Green Mountain Reservoir operations update

A picture named greenmountainreservoir.jpg

From email from Reclamation (Kara Lamb):

Starting tomorrow, we will be increasing releases from Green Mountain Reservoir to the Lower Blue River in 25 cfs increments. Like the increase the other week, this bump up in releases is in anticipation of late spring run off from the large snow pack currently reported in the Blue River Basin. The release increases will occur around 8 a.m. in the morning tomorrow, Thursday, March 3, Friday, March 4, and Saturday, March 5. By late afternoon Saturday morning, flows in the Lower Blue below the dam should be around 275 cfs. At this time, Green Mountain Reservoir is sitting at a water level elevation of 7901–that’s about 49 vertical feet from full. However, that’s about six feet higher than where we’d like the reservoir to be in late spring when run-off starts to come down. We’d like to start the run-off season closer to 7895.

Green Mountain Reservoir update

A picture named greenmountainreservoir.jpg

From email from Reclamation (Kara Lamb):

Today, February 3 2011, we increased releases from Green Mountain Reservoir to the Lower Blue River in two increments of 25 cfs, one in the morning, one in early afternoon. As a result, the Lower Blue should now be running at about 175 cfs. Currently, Green Mountain Reservoir is at a water level elevation of about 7904–about 46 feet down from completely full. However, because of the above average snowpack in the Blue River basin, we have increased releases slightly to help with what we anticipate will be a large run-off. The reservoir elevation will drop very slowly at this release rate. I will keep you posted of additional changes, if any.

Denver Water’s proposed rate increases attract the focus of councillor Jeanne Faatz

From The Denver Daily News (Peter Marcus):

The Board of Water Commissioners will hold a public hearing on Wednesday, as well as again next Wednesday, before voting on the proposal. The plan calls for an average increase for next year of $41 per year for Denver customers, or an increase of about $3.40 per month. The increase would be more than 10 percent for next year and comes as Denver Water officials warn that consumers may see an increase of 31 percent over the next three years. If approved, the increased water rates would take effect in March 2011.

Suburban residential customers would see an average increase of about $2.66 per month, or about $32 per year.

The proposal has already made a splash with Denver City Council members – but not the kind of splash that Denver Water would have liked. In addition to raising concerns over the impact a rate increase could have on constituents, Councilwoman Jeanne Faatz took the opportunity last month to raise questions over the organization of the Denver Water board itself.

Currently, the Board of Water Commissioners is a five-member board that is appointed by the mayor of Denver. Faatz questioned whether it wouldnā€™t be a better idea to switch to a board that is elected by the people, to perhaps better represent the interests of voters.

ā€œOur same people are paying these rates and they have definitely let us know that they are not interested in increased taxes and we have tried to listen to that and be responsive, and theyā€™re not interested in higher fees, and yet you all just pretty much as an enterprise get to set what you set and charge them,ā€ Faatz told Denver Water officials at a City Council briefing last month.

Green Mountain Reservoir operations update

A picture named greenmountainreservoir.jpg

From email from Reclamation (Kara Lamb):

This week, we have begun to cut back our releases from Green Mountain Dam to the Lower Blue River. Earlier this week, we began scaling down from the 730 cfs range. This morning, we cut back another 100 cfs from 500 to 400 cfs.

Denver Water, the Colorado River District and others are making progress over the Shoshone water right and Blue River Decree

A picture named shoshoneglenwoodcanyon.jpg

From The Grand Junction Daily Sentinel (Gary Harmon):

Attorneys for Denver Water and other water organizations won a weeklong stay Wednesday in the beginning of a trial on a case in federal court in which Denver Waterā€™s handling of its Blue River decree is at issue. That litigation could be set aside next week once an affidavit attesting to the progress of the parties is filed under seal in the court, River District spokesman Chris Treese said…

Denver Water also wants to get about the business of expanding Gross Reservoir near Boulder, [Denver Water General Manager Jim Lochhead] said. The agency, which serves 1.3 million people and is the stateā€™s oldest and largest water utility, needs the flexibility to move water around its system. Itā€™s looking to the settlement to offer Denver Water the kind of flexibility it needs to manage its system, Lochhead said. In addition to completing the Blue River decree, which refers to the stream that fills Dillon Reservoir, one of Denverā€™s largest water supplies, the agreement would limit the size of the Denver Water service area. It also would offer the Western Slope assurance that Denver Water would take no action to obtain more water without cooperation from the Western Slope. Once itā€™s complete, ā€œThis will be one of the most comprehensive agreements thatā€™s ever been negotiated in the state of Colorado,ā€ Lochhead said. ā€œIā€™m looking at this agreement to forge an entirely new paradigmā€ in relations between the Front Range and Western Slope.

The agreement will give the Western Slope, primarily the River District, a greater voice in the operations of the Shoshone Power Plant. The Shoshone plant generates 14 megawatts of electricity from turbines spun by the Colorado River, and its 1902 water right ensures water will flow from the headwaters of the river to Glenwood Canyon and below. If Shoshone was unable to call water downriver, the Grand Valleyā€™s domestic, agricultural and industrial needs, as well as those of four endangered fish species, would have to be met by other sources, notably the Roaring Fork and Fryingpan rivers. They join above Glenwood Springs, and those waters flow into the Colorado River in Glenwood Springs, below the Shoshone plant. Plateau Creek in De Beque Canyon also could be called down to meet the Grand Valley requirements, leaving some of those junior water rights to go unfilled.

CWCB: New transmountain pipeline conceptsĀ update

A picture named dnrpipelineconcepts309

From The Pueblo Chieftain (Chris Woodka):

The Colorado Water Conservation Board is looking at three new transmountain possibilities and two pumpback plans in the Arkansas and South Platte river basins in an analysis of supply options that could provide between 100,000 and 250,000 acre-feet per year of new water to the Front Range.

Only one of the projects, a 540-mile pipeline from Flaming Gorge Reservoir in Wyoming to Coloradoā€™s Front Range, is actively being pursued. Entrepreneur Aaron Million and the South Metro Water Supply Authority both looking are at it. The ā€œBig Strawā€ plan, or Colorado River Reconnaissance Project, was not evaluated in the latest study because of its high initial cost to build. It would bring water from the Colorado River near Grand Junction to the Front Range. Other projects studied were from Blue Mesa Reservoir and the Yampa River. The Green Mountain pumpback plan also was included in the study, although it would provide about 68,000 acre-feet annually ā€” less than the other 100,000 or 250,000 acre-feet plans.

The Arkansas Valley plans would move water from either La Junta or Avondale to Rueter-Hess Reservoir near Parker. From either place, the cost would be nearly $100,000 per acre-foot over the 50-year life of the project and supply 100,000 or 250,000 acre-feet, according to a report by CDM engineering. All of the other options come in around $80,000 per acre-foot or less over 50 years. One of the South Platte options would cost around $70,000, while the Green Mountain option is about $40,000 over the life of the project. The reason for the discrepancy would be the need for reverse-osmosis, coupled with unproven methods of zero liquid discharge, to bring Arkansas Valley water up to drinking quality…

The new report, now in draft form, will be part of a Colorado Water Conservation Board’s water needs assessment expected to be complete in January.
