About Levee

Missouri River Levee Units L-561, L-550, and L-536 are located in Atchison and Holt Counties, Missouri on the left bank of the Missouri River from approximate river mile 533 to 561. These levees were originally designed and constructed by the U.S. Army Corps of Engineers to reduce the risk of flooding from the Missouri River and tributaries to the counties floodplain. Tieback levees on the Nishnabotna River, High Creek, McElroy Creek, Rock Creek, Turkey Creek, and Mill Creek complete the levee systems of the Federal Flood Risk Reduction Projects. The network of these three levee units consist of 54 miles of earthen levees, landside seepage berm, several toe drains, 300 relief wells and 23 drainage structures. Multiple drainage structures have been equipped with mechanical pumps to remove interior water during high river stages.
