Reservoirs
Map showing major reservoirs in the Delaware River Basin.

There are several reservoirs in the Delaware River Basin, all located on tributaries. Some are used for water supply, some are used for flood control, and some are multi-purpose. Major reservoirs in the Delaware River Basin are depicted on the map to the left.

DRBC provides information on storage levels in the three New York City Delaware River Basin Reservoirs (Cannonsville, Pepacton, and Neversink), which is updated once a week, usually on Fridays.

The U.S. Army Corps of Engineers owns several reservoirs in the basin: Francis E. Walter, Blue Marsh, Beltzville, Prompton, and General Edgar Jadwin Dam. DRBC owns water supply storage in two of them, Beltzville and Blue Marsh, which are located in the Lehigh and Schuylkill sub-basins respectively; this storage is utilized in the commission's lower basin drought operating plan.

DRBC's basin-wide drought operating plan allows DRBC to call for an additional 69 billion gallons of water for flow augmentation from other basin reservoirs in times of drought emergency. View map (pdf 196 KB).

Brookfield Renewable Partners' web site for its Lake Wallenpaupack hydroelectric station provides information on current operations and schedules for expected future water discharge to the Lackawaxen River, a Delaware River tributary.
