This report is available in pdf.


Water-resources data for the 2005 water year for Virginia includes records of stage, discharge, and water quality of streams and stage, contents, and water quality of lakes and reservoirs. This volume contains records for water discharge at 172 gaging stations; stage only at 2 gaging stations; elevation at 2 reservoirs and 2 tide gages; contents at 1 reservoir, and water quality at 25 gaging stations. Also included are data for 50 crest-stage partial-record stations. Locations of these sites are shown on figures 4A-B and 5A-B. Miscellaneous hydrologic data were collected at 128 measuring sites and 19 water-quality sampling sites not involved in the systematic data-collection program. The data in this report represent that part of the National Water Data System collected by the U.S. Geological Survey and cooperating State and Federal agencies in Virginia.
