The message from the NRCS is no surprise to Coyote Gulch readers. We’ve been chronicling the precipitous decline in snowpack over the past month. Click on the thumbnail graphics for the latest snowpack map and table of snowpack and storage numbers for April 1, 2012, from the Natural Resources Conservation Service, as well as the Ogive of the Berthoud Pass Snotel (Climate Prediction Center via National Geographic). Here’s the release from the Natural Resources Conservation Service (Mage Skordahl):

The reprieve due to average or above average snow accumulation in February and the resulting boost in snowpack totals across the state was short lived. March brought dry, warm and windy weather to Colorado resulting in significant declines in the snowpack. According to Phyllis Ann Philipps, State Conservationist with the Natural Resources Conservation Service (NRCS), the latest snow surveys conducted on April 1, show that statewide snowpack has fallen to a paltry 52 percent of average. This is a decrease of 29 percentage points from the 81 percent of average measured on March 1. Statewide snowpack conditions have not been this low since 2002 when the snowpack on April 1 was also reported to be just 52 percent of average. Luckily Colorado’s reservoir storage is in better condition than it was in 2002; storage volumes statewide were reported at 108 percent of average at the end of March.

All major basins in the state reported significant drops in snowpack percentages over the last month, resulting from well below average snowfall and precipitation and warmer than average temperatures. The combined Yampa and White River basins and the Colorado River basin are both reporting snowpack’s that are less than 50 percent of average; 47 and 49 percent of average respectively. The South Platte River basin’s snowpack, while still above the statewide average, saw the largest decrease from conditions reported at the beginning of March. The basin’s snowpack dropped a substantial 34 percentage points from 89 percent of average on March 1 to 55 percent of average on April 1. Snowpack totals in the rest of the major basins ranged from 53 to 57 percent of average.

In an average winter the state receives around 20 percent of its seasonal snow accumulation in March. This winter however, March precipitation recorded at SNOTEL sites was well below average with monthly statewide totals at just 29 percent of average and instead of continuing to accumulate snow, data from SNOTEL sites revealed a snowpack beginning to melt. With April 12, the average date the snowpack reaches its peak, just around the corner there is very little hope for significant improvements to snowpack conditions prior to the spring-summer runoff season.

As of April 1, streamflow forecasts across Colorado have decreased by 20 to 40 percent of average from those issued last month. This closely mirrors the decline in snowpack percentages observed across the state. At this point all major basins in Colorado are expected to receive well below average runoff this spring and summer.

The bright spot in this month’s water supply report is that reservoir storage continues to track at near to above average volumes across the state. This stored water should help alleviate late-summer shortages.

More coverage from Bob Berwyn writing for the Summit County Citizens Voice. From the article:

Specifically, the snowpack declined by 29 percent between March 1 and April 1 during a month that usually delivers 20 percent of the total annual snowfall. All major river basins reported declines, with the lowest levels in the Yampa/White River Basin and the Colorado River Basin, both now well below 50 percent of average.

The South Platte River Basin, critical for water supplies in the Denver Metro area, saw the largest drop, falling 24 percent from 89 percent of average on March 1 to just 55 percent of average on April 1.

Jennifer Pitt (Environmental Defense Fund via National Geographic) is asking the question, Can Lack of Snow in Colorado River Basin Lead to a More Sustainable Path?. Here’s an excerpt:

If 2012 kicks off a series of dry years similar to those of 2000-2010, shortages will be unavoidable in the Lower Basin. Worse, the impact of another extended drought would be magnified by the fact that reservoirs in the basin are only 64 percent filled today, while they were completely full when the last drought started.

An extended drought starting in 2012 could drain so much water from Lake Mead as to threaten the ability of Las Vegas to access what amounts to 90 percent of its developed supply, just as it could threaten the ability of the Upper Basin to make downstream deliveries required under the Colorado River Compact. These would be untenable impacts, and certain to cause legal chaos and confusion unless the federal government, states, water users and other stakeholders start to work now on additional agreements that implement more conservation and allow more flexibility in times of extended drought.

Until fairly recently, water managers using Colorado River supplies would look to divert more water from the river. Because annual use of Colorado River water has reached (even perhaps exceeded) the annual average supply, today’s central challenges for water managers are to manage demands (through conservation) and to help facilitate more flexibility in the use of the basin’s water, such as voluntary markets, while avoiding economic and environmental damages. For many (but certainly not all) water managers in the basin, it’s a new – and difficult – way of doing business.

The bare mountaintops of 2012, and the possibility of more years like it, are certain to make the jobs of water managers more challenging. Scarcity will increase competition for water, and prices are sure to rise. But it’s also possible that this year’s dry conditions, coming so soon after the dry conditions of 2002, will continue to shift public awareness and opinion towards more support of these new ways.

As those of us who depend on the Colorado River increasingly come to recognize that extreme variability is ‘the new normal,’ water managers could find a public more willing to adapt. We need an honest discussion about the trade-offs we face, and the opportunities to do more with the water we already have.

From the Summit County Citizens Voice (Bob Berwyn):

This past month may not have been the driest March ever in the high country, but it was very close. At the official National Weather Service in Dillon, there was measurable precipitation on only four days (March 2,3,4 and 19), adding up to just 3 inches of snow and a paltry 0.20 inches of water, compared to the average 1.42 inches of water and 22 inches of snow.

From the Summit County Citizens Voice (Bob Berwyn):

Based on experimental forecasting, odds are close to 40 percent that La Niña will return for a third winter, according to Boulder-based NOAA climate scientist Klaus Wolter, who emphasized that’s not the official outlook from NOAA or the Climate Prediction Center.

A triple La Niña could spell trouble for an already dry Colorado, as three-year La Niña events are statistically linked with some the driest conditions on record in Colorado, including a historic mid-1950s drought, the mid-1970s drought that prompted ski resorts to start making snow, as well as the drought in the early 2000s that culminated with the ultra-dry year of 2002, when Dillon Reservoir nearly disappeared in a cloud of dust.

The best hope for a moisture turn-around would be a sudden switch to El Niño, which some climate models are predicting, but Wolter calculates that there’s only a 20 percent chance of that happening.

Reclamation’s Colorado River Supply and Demand Study update: ‘Protect the Flows’ goes to Washington

uppercoloradoriverbasinstatesultimatum09011925denverpost.jpg

From the Deseret News (Amy Joi O’Donoghue):

[Sarah] Sidwell’s Tag-A-Long Expeditions is one of 370 businesses that are part of the Protect the Flows coalition, which is offering up options to be weighed in the Colorado River Supply and Demand Study. The study is part of an exhaustive effort by the Bureau of Reclamation examining current and future imbalances in the Colorado River system over the next 50 years and ways to restore balance. After an evaluation period anticipated to last through June, the study will provide a road map of strategies that can be undertaken to help ensure the river system remains a viable water resource for the next 50 years…

The group said historical data complied by the U.S. Geological Survey with its streamflow monitoring system should be relied on extensively for determining a practical calculation of how much water actually exists in the system — not what is predicted through widely-varying snowpack seasons. “There is actual empirical evidence that shows how much water we can expect to have in the river,” Sidwell said.

The coalition was in Washington, D.C., earlier this year to present its ideas, which include establishing guidelines for new “water-smart” landscape designs, encouraging pool cover usage and providing incentives to farmers for incorporating more water-efficient irrigation technologies.

Flaming Gorge Pipeline: Aaron Million estimates profits at $1.4 billion

flaminggorgepipelineearthjustice.jpg

If you’ve wondered why Aaron Million has been so dogged in his pursuit of his pipeline dream facing while facing huge opposition across Wyoming, Colorado and Utah and from conservationists across the U.S., you need only to focus on the potential rewards from a for-profit operation in the middle of Colorado’s last remaining developable water in the Colorado River basin and the wealthy Denver southern suburbs. Here’s a report from Catharine Tsai writing for the Associated Press via The Colorado Springs Gazette. From the article:

His team’s confidential business proposal, shown to potential contractors, estimates construction costs of $2.8 billion to $3.2 billion, with annual operating costs of between an estimated $70 million and $90 million per year being paid by water users.

The project would initially deliver about 110,000 acre-feet of water to municipal and industrial users, with re-use available to farm and environmental interests, according to the business plan. The water would be sold under a “cost plus 20 percent” financial model, with 20 percent being added on top of costs for delivering the water. That would result in a one-time $360 million to $480 million profit to the contractor from water sales, according to the plan.

The second stage of the project would deliver up to 140,000 acre-feet, with water sold at market rates. “Potential net profit is targeted in the $1.4 billion to $2.4 billion range,” the plan said.

Though the business plan lays out staged development, Million said the project likely would be built all at once to avoid having infrastructure costs balloon over time. In any case, costs should be lower if it’s developed privately, not publicly, he said. “The project is financially sound. We think we can get it done for 30 to 40 percent less than a public sector project,” Million said.

Million provided the business proposal to The Associated Press in response to questions about an earlier version of the plan obtained by the AP.

The role of Million’s Wyco Power and Water Inc. would be to shepherd the project through the permitting process, Million said. It would earn a management fee, which could range from 0.25 percent to 3 percent of money raised for its work, he said. The plan said Wyco is seeking to raise $15 million through 2015 to get through the permitting process. Million said the amount he has raised so far is confidential, but he has said $5 million has been spent on the project during the four years since he proposed it.

“We’ve finally learned what this proposal is about. It’s about people wanting to get extremely rich off of the natural wealth of the Colorado River and the communities up and down the basin that depend on it,” said Gary Wockner of Save the Colorado.

Colorado Water 2012: Justice Hobbs pow wows with middle schoolers to talk water, rafting, recreation and water law

coloradowater2012

From The Greeley Tribune (Bridgett Weaver):

Hobbs, one of the nation’s leading authorities on water rights, was at Brentwood Middle School on Wednesday afternoon to talk to students about the adventures of water, as in river rafting and recreational water use. He was there representing the Water 2012 project, which aims to engage Coloradans in a statewide celebration of water, to raise awareness of water use and create new local and statewide opportunities that celebrate Colorado’s water, its uses and its value.

He did this by talking about a book his brother Will Hobbs wrote. The book, “River Thunder,” is about a group of young teens who take a trip down the Colorado River in the Grand Canyon. By bringing pictures from his personal outdoor and river adventures and by pulling them into the conversation with questions, Hobbs kept the students quiet and attentive.

Before talking to the large group, Hobbs participated in an eighth grade Advanced Placement history class. There he talked about Colorado’s history and his job on the Supreme Court. “We got to know things we didn’t know before, like how the court works,” said Lobna Alsrray, an eighth-grader…

Hobbs is promoting his brother’s book as part of the Water 2012 book club.
