| | SURFACE WATER |
 | | Among the more significant tributaries that supply surface water in the basin are: the Schuylkill River, the Lehigh River, and the Lackawaxen River in Pennsylvania; the Neversink and Mongaup Rivers in New York; and the Paulins Kill, Pequest, Musconetcong, and Maurice Rivers in New Jersey (Majumdar, Miller, and Sage, 1988). |
 | | The main stem of the Delaware River has an annual mean flow of 9,149 cfs at Trenton (USGS data as of 1999, http://water.usgs.gov/pa/nwis/annual/?site_no=01463500andagency_cd=USGS), which is maintained by releases from three large reservoirs on its tributaries in upstate New York (USGS NAWQA 1994). |
 | | Seventy-five percent of the Delaware River Basin's total surface water storage is contained within these three reservoirs with a total combined capacity of 271 billion gallons (Pepacton Reservoir at 140.1 billion gallons, Neversink at 34.9 BG, and Cannonsville at 95.7 BG) (Roberts and The Catskill Center, NYC Watershed Timeline, http://www.catskillcenter.org/programs/csp/H20/Lesson4/nyctime2.htm). |
