Reservoir report

New York State has several major reservoirs and dams, including the Ashokan Reservoir, the Cannonsville Reservoir, and the Pepacton Reservoir. These reservoirs are fed by several streams, rivers, and creeks, including the Esopus Creek, the West Branch Delaware River, and the Beaver Kill. The hydrology in the area is affected by the snowpack and mountains, which can significantly impact streamflow and water levels in the reservoirs. Record levels have been observed in some reservoirs in the past, but drought conditions have also been a concern, particularly during the summer months. Seasonal trends often show lower water levels in the fall and winter, with increased flows during the spring snowmelt and summer rainfall. Overall, these reservoirs play a vital role in providing clean drinking water to millions of New Yorkers while also providing opportunities for recreation and tourism.

Reservoir FAQ

About New-York dams & reservoirs

Where does the New-York 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-York 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-York 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-York's count reflects a combination of agricultural irrigation needs, flood control, hydropower, and recreation. The "Built by decade" chart above shows the timeline.
