About the ramapo river

The Ramapo River is a tributary of the Pompton River, located in northeastern New Jersey. It flows for approximately 30 miles, from its source in the Ramapo Mountains to its confluence with the Pompton River. The river has played an important role in the region's history, serving as a transportation route for early settlers and as a source of power for mills and factories. Today, the river provides drinking water for several municipalities in the area, including the city of Newark. The river is also used for recreational activities, such as fishing, kayaking, and hiking. There are several reservoirs and dams along the river, including the Pompton Dam and the Ramapo Lake Dam. These structures help to regulate the river's flow and provide additional water storage for the region. Agricultural uses of the river include irrigation for crops and grazing lands for livestock.
