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.

Colorado: Not much love for proposed new water diversions

EPA raises questions about compliance with Clean Water Act

Denver Water plans to increase transmountain diversions through the Moffat collection system will be up for comment at a pair of upcoming meetings.

FRISCO — For all the detailed information in the 16,000-page study for Denver Water’s proposed new water diversions from the Western Slope, there are still more questions than answers, according to formal comment letters filed in the past few weeks.

As currently configured, the proposal to shunt more water from Colorado River headwaters streams to the Front Range could worsen water water quality in many streams that are already feeling the pain of low flows, EPA water experts wrote in a June 9 letter. Continue reading

Will the public get more time to review and comment on the final environmental study for the largest proposed water project in years?

By Bob Berwyn

FRISCO — Boulder County’s request for more time to comment on the proposed Moffat Tunnel Collection System expansion got some high-level backup this week, as Sen. Michael Bennet formally asked the federal government for an extension.

Denver Water’s proposed new diversions from Colorado River headwaters in Grand County, specifically the Fraser River, are under federal scrutiny as the Corps considers issuing a permit for the enlargement of Gross Reservoir in Boulder County. The federal agency released the final version of a massive environmental study in April, setting a June 9 deadline for comment.

The agency received about 400 requests for an extension, many of them via a form letter. Boulder County also requested an extension, citing the need for more time to read the detailed technical reports and other documents that are part of the study, but regional Corps of Engineer Commander Joel Cross decided not to provide more time.

Massive environmental study hard to digest in just 45 days

By Bob Berwyn

FRISCO — If you were hoping to comment on the entire massive environmental study for Denver Water’s proposal to divert yet more water from the Colorado River to the Front Range, it’s time for some some speed reading.

The U.S. Army Corps of Engineers said last week that there will be no extension of the formal comment period despite a slew of requests for more time. And it’s not just environmental groups that asked for an extension. Boulder County, where there will be major impacts from the expansion of Gross Reservoir, requested more time to comb through thousands of pages of technical reports and data, but to no avail.

State of the river: Winter snows dispel some Colorado drought woes

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

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.

Summit County: Happy Birthday, Dillon Reservoir!

Dillon Marina hosting a jubilee, with free boating, music and more

By Summit Voice

FRISCO — There may be a few old-timers left who remember what Summit County looked like in the pre-Dillon Reservoir era, but most residents take the 3.200-acre impoundment for granted.

The reservoir was completed 50 years ago as a key step in Denver’s growth as a regional metropolis. The reservoir is operated by Denver Water, which serves more than 1.3 million people as the state’s largest water provider.

This Sunday (Sept. 8), the Dillon Reservoir Recreation Committee is hosting an anniversary celebration at the Dillon Marina. The free event includes pontoon boat tours, canoeing, kayaking and stand-up paddleboarding, as well as a preview of the 2014 air and water show. On land, there will be a free performance by the band Eyes Wide Open, balloon sculptures for youngsters and tasty treats from local vendors. Continue reading
