Water Resources Data Texas Water Year 2003
Volume 4. Colorado River Basin, Lavaca River Basin, and
Intervening Coastal Basins
Water Data Report TX-03-4
By S.C. Gandara
Abstract:
Water-resources data for the 2003 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 64 gaging
stations; stage and contents at 14 lakes and reservoirs;
water quality at 29 gaging stations; and data for 13 partial-record
stations comprised of 3 flood-hydrograph, 7 low-flow,
1 crest-stage, and 2 miscellaneous stations. Also included
are lists of discontinued surface-water discharge or stageonly
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. |

Choosing The Proper Volume: The 2003 water resources
data were published in
six volumes. Volumes 1 through 5 focus on streamflow
and water-quality data within
a specific basin or group of basins. Volume 6 contains
all published ground-water
data. To assist you in downloading the proper volume,
we have provided the
following resources:
Volumes 1 - 5 listing by station identification number
Volumes 1 - 5 listing by station name
