Southwestern Water Conservation District Annual Water Seminar recap #COWaterPlan #ColoradoRiver

From the Pine River Times (Carole McWilliams):

With continuing population growth in Southwestern states and ongoing drought, water issues are becoming more and more about who has to cut back their use when there isn’t enough to meet demand.

That thread ran through presentations at the annual Water Seminar on April 4 in Durango, sponsored by the Southwest Water Conservation District.

“How will we handle the water and other needs of 10 million people,” asked John Stulp, a former state agriculture commissioner and current chair of the Interbasin Compact Committee (IBCC) which is developing a State Water Plan along with nine basin water roundtables…

Harris cited a statewide statistic that with municipal water use, half is used inside and half outside. Ninety percent of the inside use returns to the stream. With outside use, 70 to 80 percent is “consumed” and does not return to the stream. The Southwest Roundtable has approved a goal to shift the percentage of municipal use to indoor, especially where the water comes from ag dry-up or trans-mountain diversion, he said.

Harris initiated the idea of legislation to limit lawn sizes in residential developments after 2016 where the water would come from a permanent transfer from ag. It didn’t get through the State Senate but will be a study topic by an interim committee on water resources during the off-session.

“The lawn bill, this is just the first time, not the last,” Harris asserted. “Reduction of lawn size is a significant conservation measure to help meet 2050 water supply.”

State Rep. Don Coram from Montrose commented “On the Front Range, they haven’t addressed storage or depleting the aquifer. They are more interested in trans-mountain diversion.”[...]

John McGlow from the Upper Colorado River Commission said curtailment such as this will affect water rights decreed after the 1922 Colorado River Compact. The Upper Basin is western Colorado, eastern Utah, southwest Wyoming, and northwest New Mexico. They have begun discussions on how cutbacks would be shared, or how to avoid getting to that point with things like fallowing fields and reducing frequency of irrigation.

“Lake Powell is our bank account for complying with the compact,” he said. It’s the cushion for the Upper Basin states to deliver mandated quantities of water to the Lower Basin states (California, Arizona and Nevada) and Mexico over a 10-year average. Navajo Reservoir also is part of that.

McGlow said 1999 was the last year that Powell was full. The goal is to get enough water into Lake Powell each year to avoid curtailment or the possibility of the water level getting too low for hydropower generation, which he said would have its own serious impacts.

The good news is there’s enough snowpack in northwest and north central Colorado that these won’t be issues this year, McGlow said…

Panelist Dan Birch from the Colorado River Conservation District said most pre-compact rights on the Western Slope are in the Grand Valley and Uncompaghre Valley. There is around 1 million AF of pre-compact irrigation on the West Slope, he said. Most of that land is in pasture or hay. Pasture can’t be fallowed, he said.

With a target to make up for 350,000 AF of post-compact use, Birch said, “I don’t think we want one-third of ag to go away. What we’re talking about is interruptible voluntary market-based contracts” for pre-compact users to reduce their water use. “This has to work for the farmers and the ditch companies,” he said.

Birch said power plants in Northwest Colorado are significant post-compact water users. “In the event of a (water) shortage, it will be important to keep critical uses going,” including power generation, he said.

Demand management is a key to avoiding Upper Basin curtailment or loss of hydro generation. “We are way behind on actual implementation of demand management,” including agricultural fallowing and reducing municipal demands, McGlow said. “It’s still a concept. It’s in its infancy.”

Fallowing and reduced irrigation are part of what’s called water banking. Panelist Aaron Derwingson said, “Pretty much everyone supports water banking in concept. It gets a lot more complex actually doing it.”

Southwestern Water Conservation District 32nd Annual Water Seminar recap #ColoradoRiver

April 6, 2014

From The Durango Herald (Sarah Mueller):

Speakers addressed the controversial practice of transmountain diversions, which takes water from the Western Slope to the Front Range. The water crosses the Continental Divide.

“Frankly, on the Front Range, they’re really not interested in depleting that aquifer; they’re more interested in the transmountain diversions,” Rep. Don Coram, R-Montrose said. “They haven’t addressed the situations of storage; their answer is there’s more water on the Western Slope than they need.”

Steve Harris, president of Harris Water Engineering, talked about the recent controversy over his idea of limiting lawn size in new suburban developments after 2016. The bill, sponsored by Sen. Ellen Roberts, R-Durango, drew fierce opposition from home builders and utility companies.

“About half the people I talked to thought that was a great idea and the other half thought I was a demon,” he said. “In this state, I know what it’s like to get between people and grass.”

Roberts rewrote the bill to call for a study of water conservation.

Another bill floating through the General Assembly would require Colorado residents to purchase “WaterSense” fixtures, such as toilets, shower heads and faucets, after 2016.

Coram said he opposed the bill because the products don’t save much water, and it’s impossible to enforce. WaterSense is a Environmental Protection Agency program labeling products as water-efficient…

Kehmeier, speaking on the water banks panel, said he’s participated in an informal marketplace among local farmers with personal reservoirs where people could lease excess water…

The Colorado Water Conservation Board also gave an update about creating the state’s water plan. Gov. John Hickenlooper directed the board last year to develop the plan. A draft plan is expected to go to Hickenlooper by the end of the year.

Snowpack news (% of avg): San Miguel, Dolores, Animas, and San Juan = 83%

April 6, 2014

From The Durango Herald (Dale Rodebaugh):

The snowpack in the combined Animas, San Juan, Dolores and San Miguel river basins was 79 percent of the 30-year median April 1; however, this week’s storms brought the basins up to 82 percent.

If it’s any consolation, the combined snowpack this April 1 is 111 percent of what it was last year on the same date.

There’s a chance late storms could increase the snowpack for the southern San Juan basins, but it’s unlikely since the maximum level is generally reached in the first week of April.

In other words, it’s as good as it’s going to get for the Animas, Dolores, San Juan and San Miguel basins…

Overall, the statewide snowpack is above normal – 115 percent of the median on April 1 and 156 percent of the April 2013 number.

But storms carried less moisture in March than in previous months. As a result, the major basins showed a slight decrease in snowpack.

Only two basins – the Colorado and the combined Yampa, White, North Platte – had snowpack percentages higher than last month.

Storms have provided runoff that improved storage in reservoirs statewide.

Reservoir storage in the Animas, San Juan, Dolores and San Miguel basins was 82 percent of average, compared with 66 percent at this time last year.

Statewide, reservoirs held 89 percent of their average, compared with 69 percent a year ago.

From The Fort Morgan Times (Michael Bennet):

A few weeks ago, I was lucky enough to strap on some snowshoes for a short hike on Berthoud Pass with local water managers and staff from the Natural Resources Conservation Service (NRCS). They were taking a manual reading of the state’s snowpack and checking the automatic SNOTEL measurement device. Undersecretary Robert Bonnie, the U.S. Department of Agriculture’s top environmental and natural resource official, and the man who oversees NRCS, also came along.

These snowpack measurement systems, some that date back to the 1900s, are a critical part of the Snow Survey and Water Supply Forecasting program that Colorado water officials rely on to anticipate river flows in the spring when the snow melts and calculate how much water will run off into rivers and reservoirs. Our state’s farmers and ranchers depend on these forecasts to decide how much and what type of crops to plant, while metropolitan leaders use the data to decide how best to meet their needs in the coming years and to prepare for potential flooding.

Beyond Colorado, these measurements are important for states downstream that depend on our watersheds. Colorado contains nine major watersheds, each with its own snowfall patterns and obligations to other states. While some of these water sources may be at 100 percent, in other regions the levels may be less than half of the normal supply. Many of the state’s water rights agreements are predicated on the level of snowpack making the accuracy of these measurements particularly important.

Recently, however, funding for the Snow Survey and Water Supply Forecasting Program was threatened by budget cuts and sequestration.

Colorado communities from across the state shared their strong concerns that cutting funding to this program would damage the accuracy of the measurements and reduce the effectiveness of this vital planning tool. In response to these concerns, we joined forces with Colorado’s water community, Senator Mark Udall, and Congressman Scott Tipton to urge the NRCS to reconsider the cuts. After working with local

communities, water managers, and the NRCS, we secured funding for the program for this winter. In addition, we secured funding in congress for the next fiscal year.


Old Uravan diversion dam on Tabeguache Creek removed, the San Miguel River tributary is now running free

From The Telluride Daily Planet (Katie Klingsporn):

In the 1930s, a 6-foot-tall, 60-feet-wide diversion dam was built in Tabeguache Creek, just upstream from its confluence with the San Miguel River, for the purposes of providing water to the Town of Uravan.

That dam remained for roughly 80 years, even as the uranium mining town was abandoned, declared a Superfund Site and razed in a reclamation project.

When Uravan shuttered, the dam stopped diverting water for human consumption. It continued, however, to block upstream passage to three species of native fish that rely on warm-water tributaries for their spawning grounds.

Until recently, that is. Thanks to a Bureau of Land Management project that was supported by the San Miguel Watershed Coalition and Nature Conservancy, the diversion dam was dismantled earlier this month.

Following two years of research, planning and securing funding, it took crews from Reams Construction a day and a half to pull all of the concrete out of the streambed.

And just like that, Tabeguache Creek was flowing free.

Peter Mueller, who is both the Nature Conservancy’s Southwestern Colorado Project Director and a board member on the Watershed Coalition, said the removal was a great thing to witness.

“One of the things that is so critical for the Nature Conservancy, the Coalition and BLM is that the native fish use these tributaries for spawning,” Mueller said. “And so to be able to remove this diversion structure and open up another eight miles of habitat, with full cooperation of both private landowners and the federal government … we were really excited about it.”

Amanda Clements, an ecologist with the BLM, said the project came about when the agency’s fish biologist was examining Colorado maps for migration barriers.

“He spotted this one,” Clements said.

Through follow-up investigation, Clements said, the BLM discovered that water rights of the dam had been determined abandoned and that removal of the structure would open up a lot of habitat for three species of native fish: Roundtail chub, Flannelmouth sucker and Bluehead sucker. All three are considered “BLM Colorado sensitive species.”

2014 McPhee Reservoir irrigation water allocation set

March 20, 2014

mcpheereservoiroverlook

From the Cortez Journal (Jim Mimiaga):

The Dolores Water Conservancy District, which operates McPhee Reservoir, forecasts full-service users will receive at least 15 inches per allocated acre of the 22 inches of a full contractual amount.

“It is an improvement from our last prediction of 11 inches,” said DWCD general manager Mike Preston. “But we will need additional snowpack in the next 6-10 weeks to fill the reservoir and deliver a full supply.”

Water officials emphasize that the 15 inches is the minimum amount expected to be delivered based on current snowpack levels measured at five different locations in the river basin.

According to a March 7 letter sent to irrigators, “If conditions completely dry out, the worst case works out to 70 percent or 15 inches per allocated acre.”

Late summer monsoon rains that recharged the soil is a major factor for the improved outlook.

Instead of soaking into the ground as it did in Spring 2013 due to a extremely dry 2012, snowmelt this year will reach the reservoir more.

“The improved soil moisture will prevent us from totally cratering like last year,” said Ken Curtis, a DWCD engineer.

Last year, full-service irrigators received just 25 percent of their total allocation, or about 6 inches of water per acre. Instead of three cuttings of alfalfa, most farmers harvested just one.

The latest water news is critical for farmers, who begin ordering fertilizer and seed now for the upcoming growing season. Calculations of how much to plow also depend on estimated water supplies.

“If we get a weather build up, it will just improve from the 15 inches,” Preston said…

If the high country received 4-6 inches of snow each week through April, managers predict the reservoir would reach its full irrigation supply.

On the down side, lower elevation snow is lower than normal. Also, because there is no carryover storage from last year’s dry conditions, McPhee reservoir will end very low and lack carry over storage for a third straight year.
