Current Reservoir Levels - selecting graph opens larger image
Typically drawn down in summer when customer demands increase, water supply reservoirs are designed to refill in the winter and spring through natural runoff and, in some cases, by pumping water into them. Reservoir storage is just one factor that NJDEP uses to evaluate drought conditions and their impact on regional drinking water supplies. |
