L601 Direct Assistance Information

Background: The L-594-601 Missouri River Left Bank Levee System experienced significant damage during the 2019 Flood Event.  This led to four (4) breaches, along with substantial other damages, occurring throughout the Levee System.

Current Action: The L-601 Levee System is no longer active in the PL 84-99 program, making it ineligible for rehabilitation assistance.  However, a priority breach impacting the I-29 corridor was identified and determined eligible for emergency operations flood fighting direct assistance.  The construction contract for this direct assistance flood fighting effort was awarded on 14 May 2019.  These initial repairs are directed at stopping the flow from the Missouri River into the area behind the levee system and providing an incremental level of flood risk management.
