June 19, 2011 - Corps: Levee L-550 overtopped in Atchison County #2011MoRivFlood

Omaha, NE -  The Missouri River Levee L-550 local sponsor reported overtopping of levee L-550, located north of Highway 136 in Atchison County, Mo., this morning June 19 to the U.S. Army Corps of Engineers.


Water levels at the Brownville gauge increased approximately two feet in a 24-hour period from 5:30 a.m. 18 June to 5:30 a.m. 19 June. State Emergency Management agencies, officials from the State of Missouri and Nebraska, and the Federal Emergency Management Agency (FEMA) Region VII have been notified.


The clay levee is located near River Mile 535.5 in Atchison County, Mo. The levee is in the Federal Program (PL 84-99) and is operated and maintained by a non-federal sponsor. It was constructed by the Corps in the late 1940s.


"People’s safety is our number one concern, so we want to stress how important it is for the public to stay off of these levees as we continue to assess the risk," said Omaha District Commander Col. Bob Ruch.


The overtopping follows weeks of high flows and increasing releases from the main stem dams in Montana and the Dakotas. The Corps encourages the public to contact their local state emergency operations center for additional information including recommended evacuations.


More information will be provided as it becomes available.
