List of largest reservoirs in Wyoming facts for kids

The following is a list of the fourteen reservoirs, in the United States state of Wyoming, that contain at least 40,000 acre-feet (49 million cubic meters) when at full capacity. In addition to in-stream reservoirs, the list includes enhanced natural lakes, notably Jackson Lake. With five of the fourteen largest reservoirs in the state, the North Platte River is the most dammed river in the state, and provides much of the state's water storage.

These reservoirs provide 10,221,672 acre-feet (13 billion cubic metres) of storage. (Some of this storage capacity, or of the water held in it, is allocated otherwise than for normal use within the state.)
