Lake Powell is a man-made reservoir on the Colorado River in Utah and Arizona, United States. It is a major vacation spot visited by approximately two million people every year. It is the second largest man-made reservoir by maximum water capacity in the United States behind Lake Mead, storing 24,322,000 acre feet (3.0001×1010 m3) of water when full. However, due to high water withdrawals for human and agricultural consumption, and because of subsequent droughts in the area, Lake Mead has fallen below Lake Powell in size several times during the 21st century in terms of volume of water, depth and surface area.

Lake Powell was created by the flooding of Glen Canyon by the Glen Canyon Dam, which also led to the 1972 creation of Glen Canyon National Recreation Area, a popular summer destination of public land managed by the National Park Service. The reservoir is named for explorer John Wesley Powell, a one-armed American Civi
