Water Resources Data Texas Water Year 2004, Volume 4

Water-resources data for the 2004 water year for Texas are presented in six volumes, and consist of records of stage, discharge, and water quality of streams and canals; stage, contents, and water-quality of lakes and reservoirs; and water levels and water quality of ground-water wells. Volume 4 contains records for water discharge at 68 gaging stations; elevation at 14 lakes and reservoirs; and water quality at 30 gaging stations. Also included are data for 11 partial-record stations comprised of 3 flood-hydrograph, 7 low-flow, and 1 crest-stage station. Also included are lists of discontinued surface-water discharge or stage-only stations and discontinued surface- water-quality stations. Additional water data were collected at various sites, not part of the systematic data-collection program, and are published as miscellaneous measurements. These data represent that part of the National Water Data System operated by the U.S. Geological Survey and cooperating Federal, State, and local agencies in Texas. Records for a few pertinent stations in the bordering States also are included.
