Texas Water Science Center

Data and Tools

USGS Texas Water Science Center operates about 850 real-time data collection sites in Texas for acquiring information on surface-water, groundwater, water-quality, and precipitation. These sites provide real-time data via satellite, radio, cellphone communication, and enable public access to the data on the Web.   

Links to our most popular data networks are available in the carousel above and in the Data Networks section below.   A comprehensive list of data networks, tools and viewers for accessing data, and data products associated with studies follows.

Cumulative Compaction of Subsurface Sediments (2017) in 13 Extensometers in the Chicot and Evangeline Aquifers in the Houston-Galveston Region, Texas.

The U.S. Geological Survey, in cooperation with the Harris‐Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, and Lone Star Groundwater Conservation District, produced a dataset through 2017 of compaction values in the Chicot and Evangeline aquifers in the Houston‐Galveston region, Texas. This dataset contains compaction values of subsurface...

Water Quality Data at Brazos River near Rosharon, from July to December 2017—A period that includes the Landfall of Hurricane Harvey

In late August and early September 2017, Hurricane Harvey made landfall on the southeastern coastline of Texas and produced a record amount of rainfall, leading to widespread flooding. From August 25 through September 1, 2017, some areas in southeastern Texas received more than 60 inches of rain with large areas receiving at least 40 inches of rain. Hurricane Harvey was the largest rainfall...

Estimated Annual Recharge to the Edwards Aquifer in the San Antonio Area, by Stream Basin or Ungaged Area, 1934–2017

The Edwards aquifer in south central Texas is one of the most permeable and productive aquifers in the United States and is the major source of public water supply for Bexar, Comal, Hays, Medina, and Uvalde Counties. The Edwards aquifer also supplies large quantities of water to agriculture, business, and industry in the region. The major artesian springs of the Edwards aquifer provide water...

Flood Inundation Geospatial data for the August and September 2017 flood event in Texas

Hurricane Harvey made landfall near Rockport, Texas on August 25 as a category 4 hurricane with wind gusts exceeding 150 miles per hour. As Harvey moved inland the forward motion of the storm slowed down and produced tremendous rainfall amounts to southeastern Texas and southwestern Louisiana. Historic flooding occurred in Texas and Louisiana as a result of the widespread, heavy rainfall over...

Time-Domain Electromagnetic Data Used in the Hydrogeologic Framework Development and Refinement for the Ogallala and Edwards-Trinity Aquifers In and Near Gaines, Terry, and Yoakum Counties, Texas

Declining groundwater levels in and near Gaines, Yoakum, and Terry Counties in the Texas Panhandle have raised concerns about the amount of available groundwater and the potential for water-quality changes resulting from dewatering and increased vertical groundwater movement between adjacent water-bearing hydrogeologic units. More than 9,800 well records, such as geophysical logs, drilling...

A Database of Peak Streamflow Derived from Interpretations of Indirect Measurements for a Crest-Stage Gage Network in Texas through Water Year 2015

In 2006, the U.S. Geological Survey (USGS), in cooperation with the Texas Department of Transportation, began collecting annual and approximately quarterly-series peak streamflow data at streamflow-gaging stations in small- to medium-sized watersheds in central and western Texas, along with selected flood-hydrograph data at a subset of these stations. The data were primarily collected from a...
