By Summit Voice
FRISCO — With Colorado River water supplies disappearing at a dizzying rate, and with a thirsty — and politically mighty — California parched by drought, the biggest water users at the table said this week they’ll invest $11 million to try and conserve significant amounts of water across all sectors, including including agricultural, municipal and industrial uses.
The Central Arizona Project, Denver Water, The Metropolitan Water District of Southern California and Southern Nevada Water Authority all signed on to what is being presented as a landmark water conservation agreement aimed at demonstrating “the viability of cooperative, voluntary compensated measures,” according to a press release from Denver Water.

No room for mistakes in the Colorado River Basin.
Conservation has to be the centerpiece of local, state and regional water planning efforts
By Bob Berwyn
FRISCO — When Congress 93 years ago formally renamed the Grand River as the Colorado, it probably didn’t have any inkling about what the mightiest river in the West would be subjected too early in the 21st century.
Now far removed from that era of hopeful development, the river is over-exploited from beginning to end. Headwater streams are diverted to water acres of bluegrass lawns in Denver, and mountain resorts mindlessly draw down tributaries for snowmaking during the low-flow season, just when trout most need the water.
Just this week, scientists said they’ve documented an astounding rate of water loss in the basin from groundwater pumping alone, which may turn out to be a worse problem than we think, groundwater development is state-regulated, therefore not as closely tracked as the diversions and storage related to major reservoir operations.
And all the pressures have intensified in recent years: More population growth, more development, more demand for food and irrigation, a 14-year dry spell across the West and a warming climate. Even without manmade global warming, ancient trees tell us that the region has seen longer and more intense droughts in the past few thousand years.
The Colorado is tapped out. Continue reading

Colorado business community weighs in on water principles
FRISCO — Vail and Eagle County residents will have a chance to get up to speed on an emerging state water plan today (July 10), with a lunchtime briefing at Donovan Pavilion in Vail, 12 p.m. to 1:30 p.m.
Gov. John Hickenlooper ordered work to begin on the statewide water plan in May 2013; a draft is due to the Governor’s Office no later than Dec. 10, 2014, with the final plan complete by December 2015.
Business leaders have developed statewide business community water policy principles to be part of Colorado’s Water Plan and are seeking regional input to finalize the principles. Working through local business chambers, this statewide initiative seeks local feedback on the principles, which address the business and economic development needs of Colorado.
- Tom Binnings of Summit Economics will discuss the economics of water from a statewide perspective.
- Linn Brooks of Eagle River Water & Sanitation District will share local water operations and policy, and discuss needs in the Eagle and Colorado River basins.
- James Eklund, executive director of the Colorado Water Conservation Board – the state agency tasked with drafting the Colorado Water Plan.
- Bryan Blakely of Accelerate Colorado and Mizraim Cordero of the Colorado Competitive Council will discuss the business community water policy principles.

Will El Niño bring a wet summer to Colorado?
Most northern reservoirs expected to fill with above average snowpack and runoff; southern basins, southeastern plains still under drought gun
By Bob Berwyn
FRISCO — Reservoirs in the northern and central Colorado high country will fill on schedule this year, water managers said Tuesday at the annual Summit County state of the river meeting, outlining their expectations for river flows and runoff volume in the Blue River Basin, a crucial water source area for both sides of the Continental Divide.
Most speakers focused was on these headwaters, but statewide maps also showed much of Colorado’s southern tier with below to well-below average snowpack — down to 50 percent in the Upper Rio Grande Basin, according to the Natural Resource Conservation Service’s Colorado snow survey program.
The dry conditions in parts of the eastern San Juans are part of regional Southwest drought footprint, which is increasing demand for this year’s runoff. Southeastern Colorado’s plains are still experiencing Dust Bowl conditions, along with parts of the adjacent south-central plains.
Troy Wineland, water commissioner for the Blue River Basin, said headwater streams in the Blue River Basin are flowing at twice their average volume for this time of year, with peak runoff yet to come. Generally, the Blue River and its tributaries reach peak flows some time in mid-June, though the exact timing is weather-dependent, Wineland said. The state of the river meetings continue the next few weeks with sessions up and down the Colorado River. Details here. Continue reading

Massive study evaluates and discloses impacts of new Fraser River diversions, expanded Gross Reservoir
Will Denver Water get permission to divert more water from the West Slope?
By Bob Berwyn
FRISCO — Not developing new water diversions from the Colorado River Basin to the Front Range would increase the chances of a major Denver Water system failure, the U.S. Army Corps of Engineers concluded in its final environmental impact study for the Moffat Tunnel Collection System expansion.
The federal agency, charged with evaluating and disclosing impacts of the proposal, claims that Denver Water customers could experience periodic raw water and treated water shortages in dry years, with Arvada, Westminster and the North Table Mountain Water and Sanitation District especially vulnerable to raw water shortages.
“Severe and more frequent mandatory watering restrictions, including surcharges, may result in a reduced quality of life and place financial burdens on customers. Though still infrequent, mandatory restrictions would reduce production, employment, and other business activity in the Denver Metropolitan area,” The Corps wrote in the executive summary of the massive study.

Widespread western drought continues
Much of the West has been very dry during the first four months of the 2014 water year.
By Summit Voice
As California experiences its worst drought in more than a century, it’s probably not surprising that some stream gages in the northern part of the state are showing all-time record low readings, with 2013 in the record books as the driest calendar year in the state’s 119-year recorded history.
Low streamflow affects water availability for agricultural, municipal, and industrial uses, water quality, water temperature, recreational opportunities, and the maintenance of fish populations.
Recent precipitation has resulted in some increases in streamflow, snowpack, and reservoir levels, but severe drought conditions remain. Without significant additional precipitation, prior conditions will quickly return leaving most streams in the state at less than 10 percent of normal for this time of year. Continue reading

Recovery stakeholders find permanent sources of water to sustain needed late summer and autumn flows
Endangered Colorado River Fish will benefit from permanent sources of water earmarked for a collaborative recovery effort. Click on the image to visit the recovery project website.
By Summit Voice
FRISCO — Four endangered native fish species in the Upper Colorado River may have a little better chance a long-term survival, as stakeholders in a collaborative recovery program found permanent sources of water needed to protect aquatic habitat for the the fish.
Water previously provided from Williams Fork and Wolford reservoirs to benefit endangered fish recovery has been replaced with permanent sources at a cost of about $25 million. The water will come from Ruedi Reservoir (5,412.5 acre-feet) and from Granby Reservoir (5,412.5 acre-feet). The releases from Granby Reservoir will also benefit flow conditions and water quality upstream of endangered fish habitat. Continue reading

Arizona researchers to focus on Colorado River flows as feds grant $7 million for 50-plus research projects
By Summit Voice
FRISCO — Arizona-based researchers will lead an effort to pinpoint how global warming will affect Colorado River flows in the coming decades, with an eye toward exploring links between Pacific Ocean climate patterns like El Niño/La Niña cycles and the occurrence of extreme wet or dry conditions.
The two-year study will result in a streamflow projection product that better accounts for physical mechanisms of weather and climate on a regional and local scale, that can be directly used by water resource providers.
The research project is one more than 50 studies funded by grants from the U.S. Department of Interior’s regional climate centers as part of President Obama’s Climate Action Plan to reduce carbon pollution, move the economy toward clean energy sources and begin to prepare communities for the impacts of climate change.

High flow experiment planned for early November to restore aquatic and riparian Colorado River ecosystems downstream of Glen Canyon Dam
By Summit Voice
FRISCO — Even with some bonus inflow in September, the past water year Oct 1, 2012 – Sept. 30, 2013) ended up as the fourth-driest on record for the Colorado River Basin as measured at Lake Powell — the key reservoir on the river that helps balance supply and demand between the upper and lower basins.
Overall water storage in the Colorado River Basin in the last 14 years has ranged from a high of 94 percent of capacity in 2000 to the present low of 50 percent at the start of the 2014 water year.

*More Summit Voice stories on the Colorado River native fish conservation program are online here.
FRISCO — State and federal biologists are considering some changes to the Colorado River Native Fish Recovery Program in the White River Basin after a discussion with stakeholders.
The endangered fish — colorado pikeminnow, humpback chub, razorback sucker, bonytail — are already protected in the White River Basin, according to The Nature Conservancy. The changes would be a firming up of management expectations.
A similar approach has been used in other basins to ensure that current and future water needs are met for people and endangered fish. The White River management plan aims to:
- identify existing and some level of future water depletions;
- develop current hydrology and projected depletions to identify the effects of past and future water development on endangered fish habitat;
- identify the role of the White River in recovery of endangered fish;
- identify flow recommendations for endangered fish habitat in the White River; and
- identify a broad range of recovery actions to be carried out by the Recovery Program to support a recovered endangered fish population in the White River. Continue reading
