ABOUT THE TEXAS WSC
USGS IN YOUR STATE
USGS Water Science Centers are located in each state.
There may be a charge for certain data requests.
The U.S. Geological Survey (USGS) provides data on streamflow, groundwater levels, and water quality at sites throughout the United States. These data are published annually in Water Data Reports by state. Published historical and near real-time water data are available at no cost via the Internet here. Specialized historical data can be retrieved upon request from computer databases at the cost of retrieval, review, reproduction, and distribution. These costs are also dependent on the size, urgency, restoration and review process of data (if necessary).
The USGS is authorized to charge for requests of data not routinely provided through our Internet site, or requests requiring more than 30 minutes of time to fill. Near real-time hydrologic data are available online for about 688 stations in Texas. The most direct way to retrieve all the data for any station of interest to you is to use the Site Information search button here . This search will find all active and discontinued stations in Texas by several selection criteria including site name, number, location, and other identifiers. Unit values (data recorded in 15-minute increments) are only available from the web site for the past 31 days. At this time historical unit values must be requested via the Data Request Form here except for those stations that are the responsibility of the San Antonio staff.
