Lake Mead in August
September 19, 2003
Lake Mead, the largest man-made lake in North America, is now at a level of 1,145 feet (349 m) above sea level, its lowest level since 1972, but not as low as its record low level of 1,083 feet (330 m) ASL in 1956. Lower than normal snowfall in the Rocky Mountains has resulted in the Colorado River supplying less than optimal water to Lake Mead. The lake, although only at 61% of capacity, still holds 5.2 trillion gallons (20 billion cubic meters) of water. This photo was taken at Hoover Dam, and one of the intakes for the power generating station appears on the left of the photo.
