Water resources data for the 1982 water year for Connecticut consist of records of stage, discharge, and water quality of streams; contents and water quality of lakes and reservoirs; and water levels and water quality of ground-water wells. This volume contains records for water discharge at 48 gaging stations; storm discharge at 7 gaging stations; stage only at 1 gaging station; tidal volume at 1 gaging station; storm rainfall at 6 gaging stations; stage only records at 3 tidal-gaging stations; contents at 35 lakes and reservoirs; water quality at 39 gaging stations, 4 lakes and reservoirs, 2 harbors, 1 precipitation station, 6 partial record stations, and 10 wells; and water levels at 59 observation wells. Also included are data for 41 crest-stage partial-record stations. Locations of these sites are shown on figures 4, 5, and 6. Additional water data were collected at various sites, not involved in the systematic data-collection program, and are published as miscellaneous measurements and analyses. These data represent that part of the National Water Data System operated by the U.S. Geological Survey and cooperating State, local, and Federal agencies in Connecticut.
