List of largest reservoirs in Colorado facts for kids

The location of the State of Colorado in the United States of America.

This is a list of the largest reservoirs in the state of Colorado. All thirty-eight reservoirs that contain greater than 40,000 acre-feet (49 million cubic meters) are included in the list. Most of the larger reservoirs in the state are owned by the United States Bureau of Reclamation and, to a lesser extent, the Corps of Engineers. Additionally, a number of these reservoirs are owned by private companies for flood control and irrigation purposes. The largest reservoir entirely contained in Colorado is Blue Mesa Reservoir, with a capacity of 829,500 acre⋅ft (1.0 billion m³). The total storage of the reservoirs on this list is 3,763,458 acre⋅ft (4.6 billion m³), although not all is allocated for use by Colorado.
