It was once a major transportation route for Native American tribes, Dutch traders, and American Revolutionary soldiers. The river's hydrology has been significantly altered over time, with wetlands drained and channels dredged for navigation and industry. Today, there are several reservoirs and dams along the river, including the Oradell Reservoir and the Woodcliff Lake Dam, which provide drinking water to millions of people in northern New Jersey. The river is also used for recreational activities such as fishing, boating, and hiking. However, it continues to face pollution challenges from urban runoff and industrial waste, and efforts are underway to improve water quality and restore habitat for wildlife.
