Omaha, Neb. – The U.S. Army Corps of Engineers announced that a partial levee breach occurred Thursday morning on Missouri River levee L-575, near Hamburg, Iowa. Early assessments have determined that this third partial breach is about 80 feet north of the previous 2 breaches.

As was the case with the previous two partial breaches, slough from the adjacent slopes filled the breach, minimizing flow over the levee in time for response by the local levee sponsor to close the breach. The sponsor is placing rip rap to help direct the flow away from repaired areas in the levee.

The levee, located at River Mile 552 in Atchison County, Mo. is in the Federal Program and is operated and maintained by the non-federal sponsor. It was constructed by the Corps.

The Corps is working closely with Iowa and Missouri Emergency Management Agencies, as well as the County Emergency Managers, the National Weather Service and Federal Emergency Management Agency Region VII to ensure the safety of all in these areas.
