Water experiments improve Colorado River conditions and habitat in Grand Canyon.

The U.S. Bureau of Reclamation has begun a High Flow Experiment (HFE) by releasing 39,500 cubic feet per second of water from Lake Powell through the Glen Canyon Dam for 72 hours, which will eventually end up in Lake Mead. The experiment is designed to restore sandbars and beaches while moving sediment downriver to improve the Colorado River corridor in eastern Grand Canyon National Park. Lake Mead is projected to rise 33 feet higher than expected this year because of snowpack levels in the Upper Colorado River Basin.
