They are also storing water in off-stream storage facilities such as Diamond Valley, which are much less environmentally destructive and much closer to users in the lower basin. It wants water managers to allow any excess water that comes into Lake Powell to flow downstream into Lake Mead. "The upper basin states on the Colorado River Wyoming, Colorado New Mexico, and Utah were . A quote from the bureau chief: Unharnessed it tore through deserts, flooded fields, and ravaged villages.

What is the timeframe for restoring Glen Canyon and a healthy Colorado River? Under the Colorado River Compact of 1922 , the upper basin is required to deliver 8.23 million acre-feet (MAF) of Colorado River water to the lower basin and Mexico every year. The safety of the water supply for Colorado River users is completely dependent upon the way it is stored, managed, and delivered. To do so, engineers built a 710ft-tall dam that severely limited the flow of the Colorado River, flooding Glen Canyon and forever altering one of the most ecologically and culturally rich areas in . It wasnt until 1928 Congress approved and appropriated funding for the most massive project on the Colorado River which promised to deliver more water and more electricity than any prior project: The Hoover Dam. Water passing the Lees Ferry gauge would flow into the more important Lake Mead and be stored as Upper Basin water.
