Water information is gathered by the USGS Texas Water Science Center to minimize the loss of life and property from natural disasters, to contribute to the conservation and sound economic and physical development of the Nation's natural resources, and to enhance the quality of life by monitoring water, biological, energy, and mineral resources.

The USGS provides real-time stream stage and stream flow, water quality, and groundwater levels for more than 650 sites in Texas.

New Insight on Ground Shaking from Man-Made Earthquake

Texas map

Earthquake activity has sharply increased since 2009 in the central and eastern United States. The increase has been linked to industrial operations that dispose of wastewater by injecting it into deep wells.

The U. S. Geological Survey (USGS) released a report today that outlines a preliminary set of models to forecast how hazardous ground shaking could be in the areas where sharp increases in seismicity have been recorded.

USGS scientists identified 17 areas within eight states, including Texas, with increased rates of induced seismicity. This is the first comprehensive assessment of the hazard levels associated with induced earthquakes in these areas.

Walker River Basin Hydro Mapper

Walker Basin Hydromapper Screenshot

The newly released web-based Walker Basin Hydro Mapper aims to provide real-time visualization of streamflow, and waterbody stage and volume in the Walker River Basin.

Real-time hydrologic data are used to monitor floods and droughts, inform water supply and agricultural water-use management decisions, and monitor and track restoration efforts in the basin.

Features include:

  • USGS streamflow-gaging stations symbolized using near real-time streamflow data
  • Reservoir capacity and current volume
  • Time slider with data back to 2008
  • Dynamic hydrographs for lakes and reservoirs and stream gages

2014 Water Data

2014 Water Data Now Available

Beginning with the 2014 water year, on-demand water-year summary reports are available from NWISWeb.

To retrieve Water Year Summaries

  • This takes you to the NWIS Web home page for the state. Several search options are available from there, including a 'Current Conditions' list of active real-time sites and the NWIS Mapper.
  • The various search options will help you find individual sites.
  • Once at the site page, select "Water-Year Summary" from the 'Available data for this site' pull-down menu.
    For example, Site 07300000 water-year summary
