Over 20 million people living in the Southwest U.S. depend upon Lake Powell for an ensured water supply and their economic well being.

Lake Powell is the 2nd largest reservoir in the United States, capable of storing 24.3 million acre-feet of water, which eliminates the need for severe water rationing during times of drought.

Water flowing through Glen Canyon Dam provides a valuable source of hydroelectricity, important to the stability of the western grid electrical system and an important source of revenue to the federal government for the repayment of irrigation projects in the Upper Basin of the Colorado River.

In addition, Lake Powell is considered by many to be the most beautiful lake in the world, with sandstone canyons and 96 major tributaries awaiting exploration.
