This is short compared to other dams. However, when viewed against the 81,200 km2 area of the lake, even a small range in Lake Superior's water level means its active volume is greater than the largest nominal in the table below.
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 km 3). Figures given are for maximum storage capacity (flood pool) of reservoirs, not regular storage volume (conservation pool).
