The Wanaque Reservoir is located in northeastern Passaic County in the Boroughs of Ringwood and Wanaque. The reservoir was created by damming the Wanaque River and its tributaries, all of which are part of the northern New Jersey’s Passaic Watershed, creating a body of water with 2,310 acres of water surface and capturing 29.6 billion gallons of water. Constructed between 1920 and 1928, the Wanaque Reservoir includes not only the reservoir but a collection of buildings, structures, and features that together comprise the reservoir complex.
