Delaware River reservoir levels have declined into the lower half of the drought warning zone (Fri., Oct. 13, 1995), triggering additional withdrawal restrictions for New York City and other communities, according to the U.S. Geological Survey’s Delaware River Master.

Total storage in the Pepacton, Cannonsville, and Neversink reservoirs today is 89.3 billion gallons, less than half of the average storage amount of 167.4 billion gallons for mid-October.

For reservoir levels to drop into the lower half of the drought warning zone means that allowable diversions of water for New York City are reduced. As of today, New York City’s allowable diversion amount is reduced from 680 million gallons per day (mgd) to 560 mgd.

New Jersey’s allowable diversion amount is reduced from 85 mgd to 70 mgd.

Flow of the Delaware River continues to decline. Today’s flow of 930 mgd is 38 percent less than the average flow of 1490 mgd on Oct. 13, at the USGS streamgauge at Montague, N.J.

Restrictions on out-of-basin transfers of water and releases from the Delaware River reservoirs allow reservoir storage to be maintained at acceptable levels and flow of the river to be kept at or above approved minimums. Under a 1954 Supreme Court decree, the Delaware River Master is empowered to limit diversions of water from the Delaware River basin, with stricter controls during times of drought.

The USGS serves the nation by providing reliable scientific information to describe and understand the Earth; minimize loss of life and property from natural disasters; manage water, biological, energy, and mineral resources; and enhance and protect our quality of life.
