Abstract
Water-resources data for the 2002 water year for Pennsylvania consists of records of discharge and water quality of streams; contents and elevations of lakes and reservoirs; and water levels and water quality of ground-water wells. This report, Volume 1 contains (1) discharge records for 80 continuous-record streamflow-gaging stations, 8 partial-record stations, 19 special study and miscellaneous streamflow sites, and 39 low-flow miscellaneous streamflow sites; (2) elevation and contents records for 13 lake and reservoirs; (3) water-quality records for 38 gaging stations and 14 ungaged streamsites; (4) water-quality records for 47 special-study station; (5) water-level records for 63 network observation wells; (6) water-quality analyses of ground water from 55 ground-water wells. Site locations are shown in figures throughout the report. Additional water data collected at various sites not involved in the systematic data-collection program are also presented. These data together with the data in Volumes 2 and 3, represent that part of the National Water Data System operated by the U.S. Geological Survey and cooperating State, local, and Federal agencies in Pennsylvania.
