Editor’s note: this news release will be updated online with more information on the streamgage records being set in Texas as it becomes available.
Rivers and streams reached record levels as a result of Hurricane Harvey’s rainfall, with about 40 U.S. Geological Survey streamgages measuring record peaks.
“During the peak period of flooding, about 81 streamgages in east and southeast Texas recorded water levels at National Weather Service flood stage,” said Jeff East with the USGS Texas Water Science Center. “All Texas rivers have already crested and have reached their highest levels.”
Immediately after the worst of the storm had passed, USGS hydrologists in Texas and from other parts of the country were deployed to measure high flood flows. The crews are also calibrating and repairing streamgages damaged by the storm to ensure they continue to transmit information in real time to users working to protect lives and property.
In Texas, the USGS has almost 800 real-time stream, lake, reservoir, precipitation and groundwater stations. The USGS, in cooperation with state, local and federal agencies, operates a nationwide network of more than 8,200 streamgages on inland rivers and streams. These gauges provide real-time data important to the National Weather Service, FEMA, the U.S. Army Corps of Engineers and other state and local partners involved in issuing flood and evacuation warnings, coordinating emergency responses to communities and operating flood-control reservoirs.
Flooding information and records known so far:
Information on record peaks and flows is still being gathered and is subject to change.
In Texas, provisional data shows new records have been set on the following rivers, streams and bayous:
