About the wanaque river


The Wanaque River is a 16-mile-long tributary of the Passaic River in northern New Jersey, USA. The river was named by the Lenape people, who called it "Wan-e-ki," meaning "place of the sassafras." The river flows through a heavily populated urban and suburban area and is prone to flooding. The Wanaque Reservoir, completed in 1928, is located on the river and is the second-largest reservoir in New Jersey. The reservoir provides water to more than two million people in northern New Jersey. The Monksville Reservoir, completed in 1987, is also located on the river and is used for recreational activities such as fishing, boating, and hiking. The Wanaque River is an important source of water for agriculture in the region, with many farms located along its banks. Despite its importance, the Wanaque River has faced pollution and environmental challenges over the years, including industrial waste and sewage discharges.
