    Guidelines for collection and field analysis of water-quality samples from streams in Texas.
    (U.S. Geological Survey., 1990) Wells, F.C.; Gibbons, W.J.; Dorsey, M.E.;
    This manual provides standarized guidelines and quality control procedures for the collection and preservation of water quality samples and defines procedures for making field analyses of unstable constituents or properties. Descriptions and procedures are given for several methods of sampling for which a variety of samplers may be used. Sample processing devices such as sample churns and filtration apparatus are discussed along with methods of cleaning. Analyses for unstable constituents or properties are by necessity performed in the field. This manual addresses analytical techniques and quality assurance for: (1) Water temperature; (2) specific conductance; (3) pH; (4) alkalinity; (5) dissolved oxygen; and (6) bacteria.

    Water Resources Data Texas Water Year 1997
    (U.S. Geological Survey, Water Resources Division, 1998-02) Gibbons, W.J.; Andrews, F.L.; Gandara, S.C.; Jones, R.E.; Barbie, D.L.
    Water-resources data for the 1997 water year for Texas are presented in four 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 1 contains records for water discharge at 111 gaging stations; stage only at 3 gaging stations; stage and contents at 35 lakes and reservoirs; water quality at 72 gaging stations; and data for 14 partial-record stations comprised of 9 flood-hydrograph, 2 low-flow, and 3 crest-stage stations. 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 micellaneous 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.
