List of largest reservoirs in the United States

Lake Powell, impounded by Glen Canyon Dam, is the second-largest reservoir in the U.S.

This is a list of largest reservoirs in the United States , including all artificial lakes with a capacity greater than or equal to 1,000,000 acre-feet (1.2 km³). Figures given are for maximum storage capacity (flood pool) of reservoirs, not regular storage volume (conservation pool). This difference is significant in reservoirs such as Kentucky Lake, whose full capacity is nearly three times that of its conservation pool.

Due to sedimentation and other factors that affect a reservoir's storage capacity over time, some data listed might not accurately reflect actual current conditions in certain reservoirs. For example, Lake Mead – the largest reservoir in the U.S. – could store more than 32.4 million acre-feet (40.1 km³) when first filled, but sediment accumulation has reduced this to 28.9 million acre-feet (35.6 km³).
