Wanaque Reservoir is a man-made lake located within Wanaque and Ringwood, New Jersey along the Wanaque River. The reservoir came into being in 1928 by the construction of the Raymond Dam along the river in Wanaque. Besides the Wanaque River, the reservoir receives water from two diversions: the Pompton Lakes intake, which takes water from the Ramapo River, and the Two Bridges intake, which takes water from the Pompton River. It is the second largest reservoir in New Jersey by volume, after Round Valley Reservoir.
