List of largest reservoirs of Colorado

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 (.0493 km3) 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-feet (1.2032 km3). The total storage of the reservoirs on this list is 3,763,458 acre-feet (4.642 km3), although not all is allocated for use by Colorado.

Key
dagger denotes reservoir not entirely in Colorado
double-dagger denotes that reservoir is offstream and fed by canals

Notes

  1. When available, volume given is the maximum flood pool, not the operational or live storage capacity.
  2. Elevations listed are in feet, and indicated the elevation of reservoir at full pool.
  3. Where multiple sources fill a reservoir, the largest inflow will be listed. If a reservoir is off-river, source river will be listed.
  4. In the case of reservoirs with multiple dams (such as Horsetooth Reservoir), all will be listed if resources allow.
  5. Because of the 1942 Republican River Compact,[17] Kansas was able to force Colorado and Nebraska to make up for water that had been previously owed. As a result, the reservoir is now dry, and will likely remain so for the foreseeable future.
