USGS Measures Flooding Across Texas

U.S. Geological Survey field crews are measuring flooding across Texas following significant rainfall over the past three days. 

Much of Texas has experienced significant rainfall, with many regions receiving more than 5 inches. This heavy precipitation has resulted in flooding, particularly along the I-35 corridor and areas to the east. 

Currently, 21 USGS streamgages show active flooding. USGS real-time maps of flood and high flow conditions for Texas can be accessed from the USGS National Water Dashboard.

This information is critical for resource managers and emergency responders to help protect life and property. These data are used by the National Weather Service to develop flood forecasts, the U.S. Army Corps of Engineers to manage flood control, and by county flood control districts and other state and local agencies in their flood response activities. 

Eleven USGS field crews are measuring floodwaters in Fort Worth, San Antonio, Austin, and Houston, with some teams also collecting water quality samples. Crews are anticipated to work throughout the weekend as NWS is predicting heavy rainfall in the region. Over the next three days, heavier rainfall is anticipated to move towards the Texas coast, potentially exacerbating flood conditions.

There are 796 USGS-operated streamgages across Texas that collect water data. When flooding occurs, USGS crews make numerous flood measurements to verify the data USGS provides to federal, state and local agencies, as well as to the public. 

For more than 130 years, the USGS has monitored flow in selected streams and rivers across the U.S. The information is routinely used for water supply and management, monitoring floods and droughts, bridge and road design, determination of flood risk and for many recreational activities.
