Hydrology Networks
United States Geological Survey (USGS) Streamflow Network - The USGS (part of the US Department of the Interior) operates this network of 7237 streamflow gages (446 in Texas) at locations throughout the US. The network provides hourly or more frequent observations of stage (water level) from which discharge (flow) is computed using a stage-discharge rating relation. The rating is defined by occasional direct current-meter measurements of discharge. All data are available through the USGS and the district offices in each state. Many of these gages provide realtime data relayed via the GOES satellite data collection system. The realtime data are provisional data that have not been reviewed or edited. These realtime data may be subject to significant change and are not citeable until reviewed and approved by the USGS. Realtime data may be changed after review because the stage-discharge relationship may have been affected by: 1) backwater from ice or debris; 2) algal and aquatic growth in the stream; 3) sediment movement; and 4) malfunction of recording equipment. Each station record is considered provisional until the data are published. The data are usually published with 6 months of the end of the water year (1 October to 30 September). Data users are cautioned to consider carefully the provisional nature of the information before using it. For further information on the USGS streamflow network visit the USGS Water Resources of the United States page at: http://water.usgs.gov/ or the USGS Texas District Office home page at: http://tx.usgs.gov/.
