The reservoir is used for hydroelectric power generation and flood control. The hydrology of the reservoir is dependent on the surrounding snowpack and precipitation, with the largest inflows coming from the Beaver River and its tributaries. The reservoir is also used for recreational activities such as fishing, boating, and camping. The surrounding area is primarily forested and there are no significant agricultural uses in the immediate vicinity. The reservoir is managed by the New York State Department of Environmental Conservation and is part of the Adirondack Park, a protected area of over 6 million acres.
