Water resources data for the 1980 water year for Virginia consist of records of stage, discharge, and water quality of streams; stage, 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 210 gaging stations; stage only at 1 gaging station; stage and contents at 10 lakes and reservoirs; water quality at 53 gaging stations and 120 wells; and water levels at 60 observation wells. Also included are data for 63 crest-stage partial-record stations. Locations of these sites are shown on figures 3 and 4. Additional water data were collected at various sites not involved in the systematic data-collection program. Discharge measurements were made at 142 coal-monitoring partial-record stations and 67 low-flow partial-record stations. Miscellaneous data were collected at 311 measuring sites and 186 water-quality sampling sites. These data represent that part of the National Water Data System collected by the U.S. Geological Survey and cooperating State and Federal agencies in Virginia.
