Snowpack news: The storms over the weekend boosted snowpack in southwestern Colorado #COdrought

From the Sky-Hi Daily News (Cindy Kleh):

[Winter Park Resort’s] snow total for the entire season stands at 376 inches – more than 31 feet – the most since 2011, according to Steve Hurlbert, Winter Park’s Director of Public Relations and Communications. “We were 28 inches ahead of our historical average of 348 inches, which dates back to when snow records began being kept in 1976. In March, we had 61.5 inches and April finished strong with 37.5 inches, which is almost exactly average (for April).”

From The Pueblo Chieftain (Chris Woodka):

Snow has started melting, but water officials still expect a banner spring runoff.

“We’re running water through the Boustead Tunnel, and the native flows in the Arkansas River basin have picked up,” said Roy Vaughan, manager of the Fryingpan-Arkansas Project for the Bureau of Reclamation.

Snowpack in Colorado dropped to 102 percent of median this week after temperatures rose last week, but peak levels still finished above average.

“The normal peak is April 10, and we were well above average at that time,” Vaughan said. “The Snotel sites can be misleading, because a lot of that snow stays deep in the canyons.”

Nevertheless, runoff is occurring sooner than usual. So far, the Fry-Ark Project has moved 900 acre-feet of a projected 73,800 acre-feet from the Fryingpan River basin to the Arkansas basin.

“In 2009, we had moved 700 acre-feet by this time. It’s to be expected in a big year,” Vaughan said.

Typically, the heaviest flows in the tunnel will continue through June, and more can come through from summer rains or late runoff. The projection of 73,800 acre-feet for the Fry-Ark project was made April 1 and assumed normal precipitation on top of the already abundant snowpack. Since then, there have been several storms over the area. A new forecast will be made this week. Average Fry-Ark imports are about 54,000 acre-feet. Last year, about 47,000 acre-feet were brought into the basin.

With warmer temperatures Arkansas River flows increased last week to nearly double the previous flows. About one-sixth of the flows upstream from Lake Pueblo is water being released by Reclamation to make room for this year’s imports.

Denver, Aurora and Colorado Springs all utilize non-potable irrigation in city operations

From the Colorado Springs Business Journal (Marija B. Vader):

Colorado Springs Utilities, along with Denver Water and the city of Aurora, all reuse a significant amount of water after it has gone through a treatment plant. It’s called non-potable water and as such is not acceptable for public consumption, cooking or bathing.

The wastewater system collects all the water from homes and businesses, then treats it to conditions set by the state health department. In most treatment centers throughout the state, the treated, non-potable water is then released back to the river or source whence it came. In Colorado Springs, Denver and Aurora, that water is recaptured and reused to water golf courses, public parks, cemeteries and the like. The systems do not extend to residential uses.

“The cost is extremely prohibitive to build such a system,” said Steve Berry of CSU. “Most customers would not tolerate the rate impact.” A system would cost in the hundreds of millions of dollars, he added…

The non-potable system in Colorado Springs provides a capacity of 13 million gallons a day during the summer. The Colorado Springs system has 26 miles of distribution pipelines that stretch to Bear Creek Regional Park, Kissing Camels Golf Course, Patty Jewett Golf Course, the U.S. Olympic Training Center, Peak Vista Community Health Centers, El Paso County, Memorial Park, Evergreen Cemetery, Colorado College, Valley Hi Golf Course and others. This program was put together beginning in 1961. Utilities’ charge for non-potable water is significantly less than for treated water.

Aurora’s non-potable system is used to irrigate parks, said Greg Baker, manager of public relations for the Aurora Water Department.

“It’s 5 million gallons a day we can save from potable use,” Baker said. The city’s irrigation season stretches from May 1 through Oct. 30.

“It makes perfect sense,” Baker said. “We don’t always want to apply potable water for irrigation.”

Denver’s non-potable system has a current capacity of 30 million gallons a day, expandable to 45 million gallons a day. The distribution system includes more than 50 miles of pipe with two major pump stations and storage tanks, according to Denver Water’s website. The system began operating in 2004, and when the recycled water system build-out is complete, Denver Water’s recycled supply will account for about 5 percent of the city’s total water volume annually, according to Travis Thompson, media coordinator for Denver Water.

Snowpack/runoff news

Statewide snow water equivalent as a percent of normal April 28, 2014 via the NRCS

From the Longmont Times-Call (Scott Rochat):

Longmont workers and residents have kept a closer eye on both Left Hand Creek and the St. Vrain River during the last week, when the annual spring runoff of mountain snowmelt began.

During a regular inspection for the water division, Longmont city workers spotted flood debris clogging a stretch of the creek near the 1300 block of Missouri Avenue. Such debris has been a special concern since a blocked channel could lead to more flooding…

In September’s flood, water from Left Hand Creek turned Missouri Avenue into a small river. The flooding left large amounts of mud in the nearby Southmoor Park neighborhood, but city officials and neighbors said afterward that damage would have been even worse without the flood-control improvements that the city made to the creek last summer.

Flows in Left Hand Creek were at 87 cubic feet per second Monday evening, according to online information from the Colorado Division of Water Resources. Levels in its parent stream, the St. Vrain River, were at about 350 cfs at midday — higher than average for the Longmont area at this time of year, according to public works director Dale Rademacher — but had fallen to 307 cfs Monday evening.

2014 Colorado legislation: SB14-103 approved with just one Republican vote #COleg

From The Mountain Town News (Allen Best):

It seems like sneering at apple pie, motherhood, and blue skies. Why would you vote against water-efficient plumbing fixtures?

Nonetheless, S.B. 14-103 was approved by the Colorado Legislature with just one Republican vote. The bill would require that only those plumbing fixtures certified under the WaterSense program can be sold in Colorado as of Sept. 1, 2016.

A representative of Gov. John Hickenlooper said on April 25 that the governor plans to canvas water leaders around the state to understand the impacts to water use and conservation…

Denver Water, the primary proponent of the efficiency legislation, estimates that broad adoption of the water-efficient toilets, urinals, shower heads, and faucets will produce 40,000 acre-feet of savings across Colorado by 2050. The agency serves a quarter of residential customers in Colorado.

“Every conversation about water should start with conservation,” says Greg Fisher, manager of demand planning for Denver Water, parroting a line used by Hickenlooper (and probably many others).

Denver has significantly reduced per-capita consumption in the last 40 years. In the early 1980s, Denver Water coined the word “xeriscaping” to embody the idea of using plants and grasses native to the climate, to minimize the amount of outdoor irrigation at homes.

The drought of 2002 drove Denver to insist, not merely encourage, cutbacks to outdoor use. After the immediate threat ebbed, however, customers generally stuck with their new ways. Residential use in Denver and its service areas in close-in suburbs now averages 85 gallons per capita per day. That’s a 20 percent reduction since the start of the 21st century, but Denver hopes to squeeze another 2 percent of reduction in the next couple years.

Change-outs of indoor plumbing fixtures have helped shrink the per-capita use, says Fisher. Using rebates and assistance to low-income residents, Denver has retrofitted 135,000 toilets in its service area since 2003. The city’s WaterSense Challenge program also provides multifamily customers bulk discounts on toilets, faucet aerators, and showerheads. Field technicians in the agency’s commercial audits replace showerheads and faucet aerators free of charge.

While outdoor use is responsible for roughly three-quarters of residential water use, indoor plumbing changes can yield perhaps surprising savings…

At a House of Representatives committee hearing in March, Republicans questioned why Colorado needs a “one size fits all” approach to water efficiency. The general tone was that government had no right getting involved in people’s bathrooms. One of those committee members, Don Coram, a Republican from Montrose, later told a gathering in Durango that he opposed the bill because it wouldn’t save much water and it was impossible to enforce, according to a report in the Durango Herald.

Fisher had first taken the idea of water-efficiency standards to legislators two years ago, but admits now that he wasn’t ready to answer all the questions. This time, he says, he was ready, and his core argument was that more efficiency does not preclude consumer choices…

WaterSense-labeled toilets use 20 percent less water per flush but perform as well or better than today’s standard toilets and older toilets that use much more water.

Toilets once needed 7 gallons of water per flush. That dropped to 3.5 gallons and then, by 1996, 1.6 gallons. Now, all toilets certified by WaterSense use 1.28 gallons or less, with some models using as little as 0.8 gallons per flush.

WaterSense-certified bathroom faucets outfitted with aerators can save 30 percent.

Why mandate WaterSense fixtures? Building codes have begun requiring greater efficiency. And consumers at The Home Depot and other places are buying them on their own…

Fisher said Denver Water decided that mandates were needed to capture the entire market, retail and wholesale, and accelerate the pace of adoption.

“If we felt comfortable that the market was going to take care of this in the near future, I don’t think we would have seen the need for the bill,” says Fisher.

But he also said that Denver, in its strategies, wants to emphasize that lifestyles need not be sacrificed even as greater efficiencies are wrung out of water supplies…

This is just one of a trio of bills aimed at increasing water conservation and efficiency that were introduced in the Colorado Legislature this year. The most controversial was introduced by Sen. Ellen Roberts, the lone Republican to cross the partisan aisle to vote for the efficiency mandate. Based in Durango, she proposed strict limits on lawn sizes in any subdivision using new imports of water in cases where farms had been dried up for municipal supplies. The idea was sent to an interim summer committee for further consideration.

Yet another bill, introduced by Sen. Gail Schwartz, a Democrat from Snowmass Village, would have allowed legal transfer of water saved by farmers and ranchers through improved efficiencies. Under her original proposal in S.B. 14-023, the saved water could have been donated as dedicated instream-flow right in the rivers and creeks. It reportedly has run into opposition because of various concerns.
