Round Valley Reservoir

Round Valley Reservoir spans 2,350 acres of water surface and reaches depths of 180 feet, making it the deepest lake in New Jersey.

The New Jersey Water Authority created the reservoir in 1960 by constructing three dams that submerged a farming community beneath its waters.

The reservoir takes its name from the circular valley surrounded by Cushetunk Mountain, which originated from the erosion of sedimentary rock.

The recreation area provides 85 wilderness campsites accessible by boat or hiking trails, with facilities including fire rings and drinking water stations.

The waters contain naturally reproducing lake trout populations, marking the southernmost habitat for this species in the United States.
