It is used as a source of drinking water for more than 3 million people in New Jersey. The reservoir's hydrology is primarily fed by the Wanaque River, a major tributary of the Pequannock River, and smaller streams that flow into it. The surface flow and snowpack providers for the reservoir include the Wanaque River and its tributaries, as well as precipitation and meltwater from the surrounding mountains. The reservoir is strictly regulated for public safety, and there are no agricultural or recreational uses allowed. However, there are several parks and hiking trails in the surrounding area that offer picturesque views of the reservoir.
