Lake Musconetcong is a reservoir located on the border of Morris County and Sussex County, New Jersey, and is part of Hopatcong State Park, which is administered by the New Jersey Department of Environmental Protection. The Musconetcong River flows through the lake.
Lake Musconetcong was created by the building of the Lake Musconetcong Dam in the mid-19th century to provide an additional water source, then known as the Stanhope Reservoir, for the Morris Canal. The lake was deeded over to the State of New Jersey with the other parts of the Morris Canal System in 1924. Boating, fishing, and ice fishing are popular recreational activities on this lake.
The lake covers 329 acres (1.33 km2), with a mean depth of approximately 5 feet (1.5 m) and a maximum depth of 10 feet (3.0 m). The lake's watershed covers 14,000 acres (57 km2). Lake Musconetcong is downstream of Lake Hopatcong, the largest lake in New Jersey and is part of its watershed.
