Riverwatch: Corps provides Information on levee overtopping at R-548 south of Brownville, Nebraska

Omaha, Neb. – The U.S. Army Corps of Engineers announced overtopping at levee R-548 late this afternoon. Water is currently going over an approximately 30-foot stretch on the southern portion of levee system. The local sponsor is onsite and is placing sandbags to cut off the flow.

The earthen levee, located south of Brownville in Nemaha, Neb., is in the Federal Program (PL84-99) and is operated and maintained by the non-federal sponsor. It was constructed by the Corps in the late 1940s. The PL 84-99 empowers the Corps to assist with immediate state and local efforts by providing supplemental and short-term needs.

This overtopping comes hours after another reported overtopping of levee L-550, located near Rockport, Mo., this morning. Map of levee locations can be found here: http://www.nwo.usace.army.mil/html/op-e/WaterMgt/Mo_River_levee_road_map.pdf

Water levels at the Brownsville gauge increased approximately two feet in a 24-hour period from 5:30 a.m. 18 June to 5:30 a.m. 19 June and are continuing to rise.

“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.

Overtopping occurs when the water is at a higher elevation than the height of a levee. Overtopping is not the same thing as a breach or levee failure. Overtopping will allow water to enter the protected area and pond to a depth associated with the amount of water overtopping the levee. Lowland areas will pond to a deeper elevation than adjacent higher elevation lands.

The Corps is in close coordination with the State Emergency Management agencies, officials from the State of Missouri and Nebraska and the Federal Emergency Management Agency (FEMA) Region to ensure the safety of all in these areas.

These overtoppings follow weeks of high flows and increasing releases from the main stem dams in Montana and the Dakotas. The Corps continues to aggressively monitor and evaluate the inundation areas.

During times of expected high water and flooding, the Corps encourages levee sponsors to carefully monitor their levees and notify the Corps immediately of any concerns.

More information will be sent when available.
