Texas Flood Watch

The need for timely, accurate, and complete streamflow data is critical during floods and heavy rains because these data are relied on by local, State, and Federal emergency management personnel for flood response purposes. The USGS Texas Water Science Center is developing flood early warning systems with elevated streamgages, redundant monitoring and reporting equipment, and multiple communication systems. These systems will give first responders and citizens reliable and timely data during rapidly changing flood events. For more information about our flood expertise, visit our Flood Early Warning Science in Texas web page.
