From the Sky-Hi Daily News (Leia Larsen):

According to National Park Service officials, the 47,600 cubic-yard debris flow changed the river channel, deposited a large debris fan, increased sedimentation in the Colorado River, degraded ecosystems and damaged the aesthetics of a wilderness area. Because the area now contains more sediment and debris that it would under natural conditions, had the man-made canal never existed and never breached its bank, the Park began exploring solutions for restoration.

On Feb. 12, Park representatives announced the availability of their “Record of Decision,” which selected the referred alternative from the Environmental Impact Statement guiding the restoration process. Plans are to remove large debris deposits from the alluvial fan in the Lulu City wetland, stabilizing slopes and banks and restoring the Lulu City wetland by removing debris piles. Some small-scale motorized equipment will be used in the stabilization and revegetation efforts, and large equipment will be used to remove debris deposits and reconfigure the Colorado River through the Lulu City wetland.

According to a Park statement, there will be “short-term, adverse impacts on natural soundscape, wilderness, water resources, weltands, visitor use and experience, and wildlife from restoration activities and the use of mechanized equipment.” The long-term benefits, however, will be the high-level restoration to the area. At this time, he Park does not have any information regarding when restoration activities will begin.

CSU Sponsors First Poudre River Forum Feb. 8

January 21, 2014
Cache la Poudre River

Cache la Poudre River

Here’s the release from Colorado State University (Jennifer Dimas):

The Cache la Poudre River is life-blood for Northern Colorado. In recognition of its importance to the area, the community is invited to the first Poudre River Forum, 10 a.m. – 4:30 p.m. on Saturday, Feb. 8 at The Ranch Events Complex in Loveland. The forum, “The Poudre: Working River/Healthy River,” will focus on all of the river’s stakeholders, representing perspectives from agricultural, municipal, business, recreational and environmental backgrounds. Topics to be discussed include:

• The water rights of agricultural and municipal diverters;
• Where the water in the Poudre comes from and what it does for us;
• Ecological factors such as flow, temperature, fish and sedimentation.

The forum will feature presentations and dialogue, including remarks by State Supreme Court Justice Greg Hobbs about how the Poudre itself was the site of early conflict and cooperation leading to the development of the doctrine of prior appropriation in the West, and how water law has evolved in recent years.

Following the event, a celebration of the river will be held until 6 p.m. with refreshments and jazz by the Poudre River Irregulars.

Pre-registration is required by Jan. 31. The cost is $25; students 18 and under are free and scholarships are available. To register, visit http://www.cwi.colostate.edu/thepoudrerunsthroughit

The event is sponsored by The Poudre Runs Through It Study/Action Work Group facilitated by CSU’s Colorado Water Institute.

Ag practices in Weld County impact RMNP, the Colorado Livestock Association hopes to help

From The Greeley Tribune (Eric Brown):

The local agriculture industry is teaming up with scientists and other experts, looking to possibly take the “biggest step yet” in addressing what’s been a major concern at Rocky Mountain National Park for several years. While Greeley is about 60 miles away from the park, ammonia drifting westward from ag operations in Weld County and surrounding areas, among other sources, has impacted the park’s ecosystem, according to studies.

Biologist Jim Cheatham said the 2006 Rocky Mountain National Park Initiative report revealed that nitrogen levels in the park are about 15 times more than natural amounts — with the excess coming in the form of nitrogen oxide from sources like fossil fuels, and also ammonia from ag operations. Such levels, according to Cheatham, have altered the vegetation composition, aquatic communities and overall natural processes of the alpine tundra the park was created to protect under its designations as a National Park, an International Biosphere Reserve and a Class I Airshed.

Now, the Colorado Livestock Association is voluntarily working with climatologists and other scientists in hopes of controlling the problem.

The Greeley-based organization is spearheading an effort to develop a warning system that will tell ag producers — based on atmospheric conditions — when they should or shouldn’t scrape manure from pens at feedlots and dairies, fertilize crops or perform other tasks that release ammonia into the atmosphere. Only when weather conditions are right does that ammonia drift from farms, ranches and dairies along the Front Range and northeast Colorado plains to Rocky Mountain National Park.

“So if we can just get more exact data about how and when that ammonia is moving into Rocky Mountain National Park … and then develop a warning system … that could really go a long way in fixing the problem,” said Bill Hammerich, president of the Colorado Livestock Association. “We know we’re not the only contributor to the issue, but we certainly want to do our part to help fix it.”

Such a warning system has been in discussions for about two years, Hammerich said, and it finally got off the ground this month, thanks to a recent $100,000 boost from the Conservation Innovation Grant program.

Cheatham said he’s “very appreciative” of the efforts being made by the Colorado Livestock Association and others, saying the development of a warning system could be the “biggest step yet” in addressing the high nitrogen levels in the park.

There’s no exact numbers showing how much of an impact agriculture operations have on the high nitrogen levels, but he said the 2006 report showed that about 55 percent of the excess nitrogen was coming from sources in Colorado, while the other 45 percent drifted in from outside the state. Cheatham said ongoing studies are attempting to pinpoint precisely how much ag and other industries are affecting nitrogen levels.

“We know agriculture’s impact is significant.”

William Brock Faulkner — a professor at Texas A&M University’s Biological and Agricultural Engineering Department, who’s helping with the warning-system endeavor — said the Colorado Livestock Association and other parties involved (Cheatham, the Colorado Corn Growers Association in Greeley and Colorado State University Atmospheric Science Department professors Jeffrey Collett and Russ Schumacher, among many others) are hoping to have about 30 to 40 producers in the region participating in a “pilot” program by March or April of next year, after more data is collected. Faulkner said some of the effort will be determining whether a warning system would even be economically feasible — not requiring producers to delay practices like manure removal, needed as part as of animal-health measures, for too many days.

But local producers say they’re willing to do their part.

“Myself and others in agriculture certainly don’t want to have a negative impact on the environment,” said Steve Gabel of Eaton, former president of the Colorado Livestock Association, and also operator of Magnum Feedyards, which has the capacity to hold nearly 25,000 head of cattle.

Gabel explained that many producers already have practices in place that help reduce the release of ammonia into the atmosphere, but added that, if a warning system can be developed, he could hold off on performing ammonia-releasing tasks for as many as a few days at a time, or even up to a week, if needed.

Cheatham said the overall goal is to ultimately cut nitrogen levels in the park by half — 1.5 kilograms of reactive nitrogen per hectare per year. He noted that it’s a “realistic and achievable goal,” but those levels would still be about seven or eight times the natural amounts of nitrogen in the park.

“We understand that, with human activity, natural levels are not achievable anymore,” he said, describing Rocky Mountain National Park as ahead of the curve in addressing the nitrogen issue compared to other parks. “But we certainly need to do what we can to control the problem.”

Grand Lake: Reclamation lays out alternatives to help restore the lake’s historical clarity

September 2, 2012

From the Sky-Hi Daily News (Reid Tulley):

Some of the alternatives for improving the clarity of Grand Lake that are discussed in the report include: Stopping pumping at the Farr Pumping Plant in July, August, and September; modify pumping at the plant during these three months; bypass Grand Lake with a buried pipeline and pump flows directly to Adams Tunnel; or bypass both Grand Lake and Shadow Mountain Reservoir with a buried pipeline and pump flows directly to Adams Tunnel…

Two standards for the clarity of Grand Lake were adopted by the Colorado Water Quality Control Commission in 2008.

The first standard is a narrative clarity standard requiring “the highest level of clarity attainable, consistent with the exercise of established water rights and the protection of aquatic life,” according to the report.

The second standard is a numerical clarity standard of a 4 meter Secchi disk depth that will be assessed by comparing 85 percent of available recordings from the months of July, August, and September. That means at least 85 percent of the measurements taken during those three months must meet the 4 meter Secchi disk depth standard, while 15 percent can be below the minimum requirement.

Rocky Mountain National Park: The Lily Lake Dam Project will start turning dirt September 4

September 1, 2012

From The Estes Park Trail (John Cordsen):

“…the only option available to the park is to repair the dam, ” said park superintendent Vaughn Baker during his May report to the Estes Park board of trustees.

The work was required after the U.S. Bureau of Reclamation rated the Lily Lake Dam, located in Rocky Mountain National Park, as a high-hazard dam. This study was released in 2010. Failure of the dam was not imminent, which gave park staff time to evaluate long-term solutions, which ultimately became one option because of the legal requirements to maintain the water rights.

The Lily Lake Dam is situated at the headwaters of Fish Creek, which flows into Lake Estes in Estes Park. Fish Creek is about 5 miles in length and the elevation difference between Lily Lake and Lake Estes is about 1,500 feet. If the dam were to fail, the ensuing floodwaters could result in the loss of life and property along Fish Creek…

Repair to the Lily Lake Dam will be done in a manner to retain the lake and its features in a manner similar to what currently exists. The repair work may last through the end of November. During the repair work, a roughly 500-foot area of the Lily Lake Trail across the dam will be closed…

The repairs will involve the removal of surface vegetation on the downstream face of the dam, stripping and salvage of topsoil, regrading the downstream face of the dam and the area around the toe of the dam, placement of filter fabric (geotextile), filter gravel and another layer of filter fabric and installation of articulated concrete blocks (ACB).

Rocky Mountain National Park: The Park Service intends to repair Lily Lake Dam

June 13, 2012

lilylakermnp.jpg

From the Fort Collins Coloradoan (Kevin Duggan):

Park superintendent Vaughan Baker said a contractual requirement that the park retain the water rights assigned to the lake and maintain the dam forced the decision to repair the aging structure rather than remove it. “It turns out we are legally obligated to keep it,” Baker said in an interview Tuesday.

The decision is tentative based on the outcome of final consultations with the U.S. Fish and Wildlife Service, Baker said. The lake is stocked with greenback cutthroat trout, which is a native but threatened species. Repairing the dam is expected to cost more than $800,000. Construction is expected to begin in the fall…

Lily Lake was a natural lake before a dam was built on its eastern edge in 1915. The dam raised the lake’s water level about 4 feet, increased its surface area from 14 acres to 17 and increased its capacity from about 39 acre feet of water to 75. The lake was added to the park in 1991 after it was acquired and saved from development by the Conservation Fund in 1989. The park acquired water rights for the lake about 10 years ago. An agreement with the Estes Valley Land Trust requires the park to retain the water rights and maintain the dam in perpetuity, Baker said.

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

November 28, 2011

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.”
