Lake Powell could drop below the level needed to generate power at the Glen Canyon Dam this year if other ways of increasing the elevation of the lake aren’t used.
Water managers made emergency releases of water from Colorado’s Blue Mesa Reservoir on the Gunnison River and Utah’s Flaming Gorge Dam on the Green River last year, which slowed but did not stop dropping levels in Lake Powell.studying modifications to the Glen Canyon Dam that would allow for power generation at lower water levels
Brad Udall, senior water and climate research scientist at Colorado State University, said at the Stegner Center symposium that the average annual temperature in the Colorado River basin has not dipped below the last century’s average since 2000 and more warming is likely, which is expected to further decrease river flows in the near future.
“We need to remove some demands permanently, not just temporarily,” Udall said. “We have a system that’s out of balance with more use than water, and the only lever we currently control is the demand lever.” “My biggest fear,” Udall said, “is that it’s easier to let the system crash than it is to find the painful solutions that are needed.”system crash as letting the two largest reservoirs in the U.S. — Lake Mead and Lake Powell — empty because of an inability to respond to declining flows.
