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.

Continuous monitoring and discrete water-quality data from groundwater wells in the Edwards aquifer, Texas, 2014–15

In cooperation with the San Antonio Water System, continuous and discrete water-quality data were collected from groundwater wells completed in the Edwards aquifer, Texas, 2014-2015. Discrete measurements of nitrate were made by using a nitrate sensor. Precipitation data from two sites in the National Oceanic and Atmospheric Administration Global Historical Climatology Network are included in...

Estimated Annual Recharge to the Edwards Aquifer in the San Antonio Area, by Stream Basin or Ungaged Area, 1934–2016

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...

Biological and physical data for zebra mussel (Dreissena polymorpha) veligers collected from a coupled lake-stream ecosystem in north Texas, 2012-2014

Dispersal, establishment, and spread of aquatic invasive species such as the zebra mussel (Dreissena polymorpha) can be influenced by riverine velocities and volumetric flows in invaded lake-stream ecosystems. Zebra mussels, which have a planktonic larval form (veliger), disperse rapidly downstream from a source population. Concentrations, dispersal, and body conditions of zebra mussel...

Data Release for Water-quality and chemical loading data from the Geronimo Creek and Plum Creek watersheds, south-central Texas, April 2015—March 2016.

Located in south-central Texas, the Geronimo Creek and Plum Creek watersheds have long been characterized by elevated nitrate concentrations. From April 2015 through March 2016, an investigation was done by the U.S. Geological Survey, in cooperation with the Guadalupe-Blanco River Authority (GBRA) and the Texas State Soil and Water Conservation Board (TSSWCB), to assess nitrate (as nitrogen)...

The importance of parameterization when simulating the hydrologic response of vegetative land-use change, SWAT simulation

The Soil Water Assessment Tool (SWAT) model was used to simulate the hydrologic response of a watershed in south-central Texas within the Honey Creek State Natural Area for the time period 2001 to 2010; the simulation was focused on simulating the hydrologic outcomes of brush management. Specifically a SWAT2012 (Arnold et al., 2012) model of the watershed was built using the ArcSWAT tool (...
