About the rockaway river


The Rockaway River is a 35-mile-long river that flows through Morris County, New Jersey. It was used by Native Americans for fishing and transportation prior to European settlement. The river has a drainage area of 129 square miles and is fed by numerous tributaries. The river is heavily regulated by four major reservoirs and dams: Boonton Reservoir, Jersey City Reservoir No. 3, Splitrock Reservoir, and Lake Hopatcong. The largest of these is Lake Hopatcong, which was created by the Morris Canal and completed in 1831. The Rockaway River is a popular destination for recreational activities such as hiking, fishing, and kayaking, and it also provides water for agriculture and drinking water for municipalities in New Jersey.
