Ruedi Reservoir will pay a price for warm, dry April — The #Aspen Times #FryingpanRiver #RoaringForkRiver #ColoradoRiver #COriver #aridification

From The Aspen Times (Scott Condon):

Reservoir expected to reach only about 90% of capacity this summer

The dry, warm month of April prevented the snowpack from building and sunk the chances to fill Ruedi Reservoir this summer, according to the U.S. Bureau of Reclamation…

The snowpack in the upper Fryingpan Valley was only about 60% of median as of May 1, he said. Forecasts are for runoff into the reservoir to be only about 55% of average…

Ruedi Reservoir is at about 60% full right now. It holds 102,000 acre-feet of water. It would need about 42,000 acre-feet to fill.

Current projections are for it to reach about 90,000 acre-feet this summer, according to Miller…

The Roaring Fork River basin, like much of Colorado and the Western United States, has been battling a prolonged drought. AccuWeather Inc. reported Wednesday that 75% of the Western U.S. is experiencing drought conditions. About 21% of the areas are facing exceptional drought, which is the most extreme…

A lower water level in the reservoir also will mean lower releases into the lower Fryingpan River through the summer. Water levels won’t be as high as usual in late spring and early summer, so there won’t be a disruption to the Gold Medal trout stream.

However, low water levels and high summer temperatures are a regular cause for concern. The Basalt-based Roaring Fork Conservancy has sounded the alarm in past summers about high water temperatures stressing trout.

Water releases could increase in June once downstream entities that possess senior water rights make a “call” for water for agricultural uses, Miller said.

April Long, director of the Ruedi Water and Power Authority, said the reservoir is used to meeting numerous water needs in the Roaring Fork Valley and on the Colorado River system. It is hard to know the full impact of the reservoir not filling, she said.
