List of largest reservoirs of Wyoming

What follows is a list of the fourteen reservoirs in the state of Wyoming, the United States, that contain at least 40,000 acre feet when at full capacity. In addition to in-stream reservoirs, the list includes enhanced natural lakes, such as Jackson Lake. With five of the fourteen largest reservoirs in the state, the North Platte River holds the distinction of being the most dammed river in the state, as well as providing much of the water storage for the state.

The fourteen reservoirs on this list provide 10,221,672 acre feet of storage, though not all is allocated for the state of Wyoming.
