Round Valley Recreation Area Overview

The brisk blue waters of Round Valley Reservoir and scenic Cushetunk Mountains frame a recreation space for boating, camping, fishing, picnicking, and lifeguarded swimming.

Round Valley Reservoir covers 2,350 acres and reaches approximately 180 feet deep, making it the second-deepest lake in New Jersey and largest reservoir. At full capacity the reservoir holds up to 55 billion gallons of water. The lifeguarded swimming impoundment provides a place for summertime visitors to enjoy the water. Round Valley is also the only New Jersey state park that offers wilderness camping. The campsites on the south-eastern side of the reservoir are only accessible by backpacking 3 to 6 miles along a steep and rugged trail or by boating. The park is open year-round, hikers enjoy fall foliage, cross-country skiers and sledding enthusiasts congregate at Round Valley in the winter months, and birders flock to the shoreline to watch the return of birds in the spring.

Round Valley’s reservoir covers 2,350 acres and reaches approximately 180 feet deep, making it the second-deepest lake and largest reservoir in New Jersey. At full capacity the reservoir holds up to 55 billion gallons of water.

The erosion of soft sedimentary rock carved the natural Round Valley out of the surrounding mountains. In 1960 the New Jersey Water Authority constructed three large dams and flooded Round Valley with water pumped in from the South Branch Raritan River, establishing the reservoir. The Cushetunk Mountain, lying on a bed of igneous rock at the reservoir’s east end, still stands over Round Valley, rising 500 feet above the reservoir’s shoreline and 834 feet above sea level.

The name “Cushetunk” possibly comes from the Lenape meaning “place of hogs” in reference to the wild hogs that once lived here. Interpretations of the name “Cushetunk” vary, within the Munsee language places that contain an “–unk” suffix often refer to mountains where as ­“–ink” or “–ing” names would refer to valleys.

Today the New Jersey Water Supply Authority manages the reservoir, monitoring water levels and carrying out construction work as part of the Round Valley Reservoir Project. The NJ Division of Fish & Wildlife historically stocked the reservoir with lake trout from 1977 through 1995. The population is closely monitored by the Bureau of Freshwater Fisheries and it the population is currently self-sustaining through natural reproduction in the reservoir and modifications in fishing regulations in response to changes in the population dynamics.

The Cushetunk Mountain, lying on a bed of igneous rock in Round Valley at the east end of the lake rises 500 feet above the shoreline and 834 feet above sea level. The Lenape called the mountain "Cushetunk" meaning "place of hogs" after the wild hogs found there.

Round Valley Recreation Area is the only NJ state park that offers wilderness camping, each campsite is in a secluded clearing in the woods along the south-eastern shoreline of the reservoir at the base of the Cushetunk Mountain.
