GRAND JUNCTION — Bringing more certainty to an unruly and unpredictable Colorado River system was a common theme among water managers speaking at the Colorado River District’s annual seminar Friday.
Although the drought that has gripped much of the Colorado River basin for the past 16 years has eased up a bit, population growth and the long dry spell have pushed the river’s supplies to the limit, with every drop of water in the system now accounted for.
Meanwhile, the effects of climate change on the Colorado’s future flows are still a big question mark, and it could mean wide variability in the years to come, with periods of punishing drought followed by a sudden record-setting wet year, as California recently experienced.
Bill Hasencamp, general manager of Colorado River resources for the Metropolitan Water District of Southern California, described how in April 2015, snowpack in the Sierras was at an all-time low. But by this spring, it was at an all-time high, after a winter of heavy precipitation.
The change in snowpack eventually lead to huge fluctuations in water prices – from $1,800 per acre-foot at the height of the drought to just $18 per acre-foot this year, Hasencamp said.
That kind of turbulence places enormous pressure on the Colorado River Basin’s big municipalities, which must secure their water supplies for millions of people, said Eric Kuhn, the general manager of the River District, which is based in Glenwood Springs and helps protect Western Colorado’s water resources.
