PROJECT ALERT NOTICE (IA) USGS crews respond to major flooding in Iowa

Date: Sat, 08 Sep 2018 11:58:16 EDT

Summary: Heavy rains over the last week have caused many streams in Iowa to go over flood stage across the state, resulting in USGS crews being deployed to these locations.

Several rounds of rain events over the last week have resulted in many streams in Iowa to rise above the National Weather Service (NWS) Flood Stage, with some locations going into Major Flood Stage. Areas primarily affected by the rains are in eastern Iowa in the Cedar, Iowa, Skunk, and Wapsipinicon River basins. 20 USGS streamgages in Iowa are currently above the NWS Flood Stage, with six of those locations being over Major Flood Stage.

Several USGS crews have been deployed to the flooded areas this past week. Today, one USGS has been deployed to measure streamflow on the Cedar River upstream of the city of Cedar Rapids. Tomorrow, one crew is scheduled to measure streamflow at the streamgage in Cedar Rapids where the river is forecast to reach Major Flood Stage.

All streamgages appear to be working. Communication is being made with the NWS, U.S. Army Corps of Engineers, and emergency managers primarily through NWSChat.
