U.S. Geological Survey field crews are measuring flooding on rivers and streams across southwestern and southern Missouri and northeast into the St. Louis area.

Heavy rainfall since Friday evening has led to widespread flash flooding. Six USGS crews are measuring high flood flows and verifying streamgage operations on the Arkansas, White, Gasconade, and Meramec River valleys. So far USGS crews have measured six occurrences of record peak flows for St. Louis County urban gaging locations and have also measured six occurences of records peak flows in the Southwest portion of Missouri, with more occurrences of record peaks expected.

The USGS is collecting critical streamflow data that are vital for protection of life, property and the environment. 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 local agencies in their flood response activities. 

There are 265 USGS-operated streamgages in Missouri that measure water levels, streamflow and rainfall. When flooding occurs, USGS crews make numerous streamflow measurements to verify the data USGS provides to federal, state and local agencies, as well as to the public.

For more than 125 years, the USGS has monitored flow in selected streams and rivers across the United States. 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.
