List of largest reservoirs in Colorado

List of the largest reservoirs in the U.S. State of Colorado From Wikipedia, the free encyclopedia

This is a list of the largest reservoirs in the state of Colorado. All forty 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 3,804,458 acre⋅ft (4.7 billion m3), although not all is allocated for use by Colorado.

Notes

  1. [1]
    When available, volume given is the maximum flood pool, not the operational or live storage capacity.
  2. [2]
    Elevations listed are in feet, and indicated the elevation of reservoir at full pool.
  3. [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. [4]
    In the case of reservoirs with multiple dams (such as Horsetooth Reservoir), all will be listed if resources allow.
  5. [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.
