OTTUMWA, IOWA -- The National Weather Service has issued a Flood Warning, in effect until Saturday night, for the Des Moines River in Wapello County. The river is expected to crest at 13.2 feet in Ottumwa by Friday evening then fall back under flood stage (11 ft) by Saturday night. The City of Ottumwa is protected by a levee up to a 25-foot river stage, but flood-prone properties in the rural areas up and downstream of Ottumwa may be affected.
Individuals with rural property along the river are advised to take appropriate actions in anticipation of waters above flood stage. Property owners in downtown Ottumwa and in other low-lying areas are being advised to deploy sewer backflow prevention at this time to prevent basement flooding. The downtown area is especially prone to sewer backups during high-water events on the Des Moines River. Most floor drains are designed to accept a plug. Owners of drains with float plugs should check the float to ensure proper operation. Residents and businesses with questions about plugging drains should consult a licensed plumber.
Residents are encouraged to monitor the local media or their NOAA Weather Radio for the latest weather advisories from the National Weather Service. Up to date information about the river level can be found online at the United States Army Corps of Engineers website www.Rivergages.com.
