Water Resources Data Texas Water Year 2004
Volume 4. Colorado River Basin, Lavaca River Basin, and
Intervening Coastal Basins
Water Data Report TX-04-4
By S.C. Aragon Long, B.D. Reece, D.R. Eames
Abstract:
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. |

Choosing The Proper Volume: The 2004 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
