Interagency Flood Risk Management (InFRM)

In 2014, the Federal Emergency Management Agency (FEMA) began sponsorship of the InFRM team initiative to allow Federal teams across the States of Texas, Oklahoma, New Mexico, Louisiana and Arkansas to better align and integrate. Currently, the InFRM team is comprised of FEMA, US Army Corps of Engineers, US Geological Survey, and the National Weather Service. Information about the Interagency...

Texas Water Dashboard

The Texas Water Dashboard is a web mapping application that presents U.S. Geological Survey (USGS) real-time stream, lake, reservoir, precipitation, and well data in Texas in context with current weather and hazard conditions. Real-time measurements from over 750 USGS observation stations in Texas are accessible from the map viewer, along with complementary map layers such as current precipitation...

Water On-The-Go

“Water On-the-Go” is a map-based web application that gives people easy access to current conditions in streams across Texas. It was developed to help raise water awareness during floods and normal conditions. The mobile-friendly website offers three ways to view streamflow or other data, including using your phone’s GPS system, clicking on an area of interest, or by searching for a physical...

Bandera Flood Early Warning Tool

Risk of future flooding events in the Bandera County area highlights a critical need for a flood warning system. As part of the flood warning system, a tool set is needed to enhance the communication of flood risk and provide emergency managers additional information necessary to better mitigate the impacts of flooding. The USGS Texas Water Science Center is helping build this tool set through...

Peak Flow Science in Texas

Annual peak streamflow (peak flow) at a streamgage is defined as the maximum instantaneous flow in a water year. A water year begins on October 1 and continues through September 30 of the following year. This definition of a water year is used because it more closely follows seasonal weather patterns. Peak flows in Texas can range from zero flow in very dry basins to flows that cause flooding and...

Inundation Mapping Science in Texas

Flood-inundation maps created by the USGS Texas Water Science Center (TXWSC) allow users to view the possible extent and depth of flooding during a specific type of storm event. Flood inundation maps may be created using hydraulic models or by using data collected after a storm event (high-water marks). Visit the links below for more information on our data and science.
