Rivers and streams reached record levels as a result of Hurricane Irma’s rainfall, with about 60 U.S. Geological Survey streamgages measuring record peaks.

“During peak flooding, about 32 streamgages in  Florida recorded water levels at flood stage,” said Richard Kane with the USGS Caribbean-Florida Water Science Center. “Several gauges, including Santa Fe River at Worthington Springs, FL  that have been in operation for more than 50 years, have recorded new peaks.”

As crews continue to assess and recover from damage caused by Irma, USGS hydrologists and hydrologic technicians in Florida and from other parts of the country have been 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 Florida, the USGS has over 900 real-time stream, lake, reservoir, precipitation, water quality, 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.

Information on record peaks and flows is still being gathered and is subject to change.
