Science team tracks effects of historic pulse flow
FRISCO — Last May’s pulse flow in the Colorado River helped revive vegetation along a huge swath of the river’s edge, triggering new plant growth and raising the water table in the delta. After comparing satellite images taken August 2013 with new images from this year, scientists calculated a 23 percent increase in the greenness of riparian zone vegetation. Continue reading

Can critical habitat help recover vanishing western yellow-billed cuckoos?
Proposed protections not popular with western water users
FRISCO — Threatened yellow-billed cuckoos will have to hang on just a bit longer before the U.S. Fish and Wildlife Service finalizes a critical habitat proposal. The agency this week announced it is extending a public comment period on the plan for another 60 days, through Jan. 12, 2015.
The agency announced its original critical habitat plan back in August, proposing to designate 546,335 acres of critical habitat in 80 separate units in Arizona, California, Colorado, Idaho, Nevada, New Mexico, Texas, Utah and Wyoming.
Now, federal biologists say they want more input on the birds’ biology and habitat and justification for exclusions from critical habitat. The agency also seeks information on the incremental economic effects of the proposed critical habitat designation. Continue reading

Discovery boosts hopes for long-term recovery
FRISCO — Colorado River anglers may favor big brown lunkers and splashy rainbows, but those trout are, for the most part, relative newcomers.
The river’s real natives are bony, powerful fish that evolved to survive in a challenging environment. Huge flooding flows in the spring, when the water runs thick with silt, or, at the opposite end of the spectrum, low flows during the fall or sustained drought, when the river is sometimes reduced to a trickle.
Among those native species is the endangered razorback sucker, long the focus of a huge recovery effort that may get a boost from the recent discovery that the fish are spawning in the Lower Colorado, specifically in Grand Canyon National Park, where they haven’t been seen since the 1960s.

Storage still near all-time lows
A 2014 water year map shows the continuing drought conditions in California, as well as dry patches from Texas, extending north into Oklahoma.
FRISCO — Near-average inflow to Lake Powell the past 12 months helped maintain storage at a similar level to last year in the key Colorado River reservoir. According to the Bureau of Reclamation. Continue reading

Water experts to discuss role of agriculture in Colorado River puzzle
Can ag water save the Colorado River?
FRISCO — A new $11 million effort to keep water flowing in the Colorado River to Lake Powell could up the pressure on Colorado farmers and ranchers to sell or lease their water.
In fact, agriculture is in the crosshairs in Colorado, according to the Colorado River Water Conservation District, which represents western Colorado water interests. Low water levels in Lake Powell and Lake Mead — the key storage buckets on the Colorado — have prompted measures to put more water in the river.
The CRWCD’s annual water seminar (Sept. 19, Grand Junction) will focus on what that means for western Colorado, with panel discussions and presentations on ag efficiency, the worth of ag efficiency and how ag efficiency works with the chief goal of sustaining ag as a viable industry.

Pumphouse site to get new play feature for boaters
FRISCO — Along with the incredible natural terrain of the Colorado River through Gore Canyon, boaters will soon also have an artificial place to play. The Kremmling Field Office of the Bureau of Land Management this week announced approval of the proposed Gore Canyon whitewater park at the Pumphouse Recreation area, west of Kremmling in the Upper Colorado River Valley.

Near critical shortages in California prompt action

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.
