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.
