L550 Levee Restoration Information

Background: The L550-561 Missouri River Left Bank Levee System experienced significant damage during the 2019 Flood Event.  This led to seven (7) breaches, along with substantial other damages, occurring throughout the Levee System.

Current Action: Two priority breaches impacting the I-29 corridor have been identified for initial repairs.  The construction contract for these two breach repairs was awarded on 11 June 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.  Follow-on actions to further repair the levee system and provide additional flood risk management are being coordinated within the PL 84-99 program.
