Colorado: Annual State of the River sessions include vital information on snowpack, stream flows and reservoirs

Colorado River Basin snowpack and streamflow forecasts now similar to 1977, 2002 and 2012 drought years

Staff Report

FRISCO — Continued drought in the Far West, along with Colorado’s push to develop a first-ever statewide water plan, should be reason enough for Coloradans to take an interest in the state of the Colorado River.

One of the best chances to get a user-friendly update is at the annual State of River meeting, sponsored by the Blue River Watershed Group.

Hands-on water experts will explain how this year’s snowmelt will play out and how that affects operations of Dillon Reservoir and Green Mountain Reservoir — both for water deliveries downstream and for onsite recreational use.

To accommodate a bigger turnout, the State of the River presentation has been moved to the Silverthorne Pavilion (Tuesday, May 5, 6-8 p.m.) Continue reading

Colorado River managers downgrade flow projections

Lake Powell expected to see about half of average inflow

FRISCO — Federal water managers downgraded their expectations for Upper Colorado River flows by several notches in the past few weeks, as warm and dry early spring conditions across most of the basin nibbled away at the mountain snowpack that sustains the river’s flows through the summer.

The Bureau of Reclamation today said they expect inflows into Lake Powell to be just 3.75 million acre feet during the key April to July runoff season. That’s just 52 percent of the 1980-2010 average and down 1.35 million acre feet from the projections of just a month ago, when the agency was hoping for 5.1 million acre feet of runoff.

Storage still near all-time lows

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

Colorado farming, ranching water ‘in the crosshairs’ as big reservoirs dwindle

Water experts to discuss role of agriculture in Colorado River puzzle

Can ag water save the Colorado River?

Staff Report

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.

Climate: USGS says most California streams flowing at less than 10 percent of normal

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

More quagga mussels found in Lake Powell; Is the Lower Colorado River ecosystem at risk?

National Park Service seeking input on mussel management plan

By Summit Voice

FRISCO — The battle to keep Lake Powell free of non-native mussels is tilting toward the aquatic invaders and federal resource managers are concerned the invaders may spread into Glen Canyon.

As of January, the National Park Service reported finding — and removing — about 1,300 hundred adult quagga mussels, and managers at the reservoir said they’re finding more as the season progresses.

In response, the park service is developing a quagga-zebra mussel management plan to help the the agency decide what tools are appropriate to support the ongoing management of invasive mussels in Glen Canyon now that quagga mussels are present in Lake Powell. Continue reading

Lake Powell: Going, going … gone?

High flow experiment planned for early November to restore aquatic and riparian Colorado River ecosystems downstream of Glen Canyon Dam

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.
