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