Wanaque Reservoir, New Jersey reservoir
Wanaque Reservoir is a large water storage facility in northeastern Passaic County, New Jersey, stretching for about 6 miles (10 kilometers) and supported by eight dams. The Raymond Dam, the largest structure, spans 1,500 feet (457 meters) and works together with multiple earth and concrete dams to form a complex system monitored by gatehouses, pump stations, and administration buildings.
Construction on Wanaque Reservoir began in 1920, with the main dam completed in 1928 and the system operational by 1930. The decade-long project transformed the region by providing reliable drinking water to communities including Newark, Kearny, Montclair, and Passaic.
The reservoir is seen by local people as a symbol of progress and community development. Its creation allowed many towns in the area to expand and grow without worrying about water shortages.
The area offers easy walking paths along the dams and around the water, best enjoyed during clear weather. Access is free, but swimming and boating are not permitted, so visitors should plan for walking and observing the water and landscape.
During severe droughts, water levels drop dramatically and the reservoir floor becomes visible, revealing cracks in dry ground and unexpected landscapes beneath. These rare dry periods highlight the resilience of the dams and the critical role the facility plays during water scarcity.
