Federal water managers simulate flooding flows in Colorado River
By Summit Voice
SUMMIT COUNTY — Water may be in short supply in the West this year, but that didn’t stop federal officials from cranking open the valves of Glen Canyon Dam to unleash what’s unromantically being called a high-flow experimental release. The release won’t change the overall water balance in the Colorado River system, as adjustments are made at other times.
The five-day high-flow regime will lower Lake Powell by up to 2.5 feet in just a few days and send more than 42,000 acre feet of water surging through Glen, Marble and the Grand Canyon before it ends up Lake Mead. A detailed FAQ is online here.
