Reservoir report

New Jersey has several major reservoirs, including the Manasquan Reservoir, the Round Valley Reservoir, and the Wanaque Reservoir. These reservoirs are fed by a variety of streams and rivers, including the Manasquan River, the Raritan River, and the Wanaque River. The state's location in the northeastern United States means that snowpack and mountain runoff are important factors in the hydrology of the area.

Record levels and drought conditions have been observed in New Jersey in recent years, with severe drought conditions experienced in 2020. Seasonal trends show that streamflow and reservoir levels tend to be highest in the spring and lowest in the fall, with the summer months often experiencing drought conditions. Despite these challenges, New Jersey has worked to improve its water infrastructure, including dam and reservoir management, to ensure a reliable supply of clean water for its residents.

Reservoir FAQ

About New-Jersey dams & reservoirs

Where does the New-Jersey dam data come from?

The U.S. Army Corps of Engineers National Inventory of Dams (NID) plus state water-resource agencies. Snoflo joins these public records with live USGS streamgauge readings downstream where available. The NID is the canonical federal dam registry.

What does Hazard Potential mean?

USACE classifies every dam by what would happen if it failed: Low (no loss of life expected, minimal economic damage), Significant (no loss of life but economic, environmental, or lifeline damage), High (loss of life expected). It's a downstream-consequence rating, not a likelihood of failure.

What is Normal Storage in acre-feet?

The volume of water the reservoir holds at its normal operating level, measured in acre-feet. One acre-foot is about 325,851 gallons or 1,233 cubic meters — the amount needed to cover one acre to a depth of one foot.

Why are some New-Jersey dams missing storage or height data?

USACE NID records can have gaps for small or older dams that pre-date federal reporting requirements. Snoflo surfaces whatever the canonical record contains. If a dam you care about has incomplete data, contact the operating agency or USACE for updates.

Can I see live water levels?

Yes — tap any dam name to open its detail page, which pulls live storage data from USGS streamgauges or operating-agency feeds where available. Historical levels and seasonal averages are also shown.

Why does New-Jersey have so many dams?

The U.S. has over 90,000 dams — most built between 1930 and 1980 during the federal water-development era. New-Jersey's count reflects a combination of agricultural irrigation needs, flood control, hydropower, and recreation. The "Built by decade" chart above shows the timeline.
