Six Mile Diversion Levee Restoration Information

Background: The Six Mile Diversion Levee was damaged during the May/June 2019 Arkansas River Flood Event. Six mile Levee is part of the McLean Bottom levee system.  This section of the levee is USACE Federally Constructed and USACE Federally Operated. The Six Mile Levee is not part of the USACE Levee Rehabilitation and Inspection Program.

The McLean Bottom Levee system is divided into three segments:

  • Six Mile Diversion Levee (USACE operated and maintained)
  • McLean Bottom Levee District No. 3 (Locally operated and maintained by the McLean Bottom Levee District No. 3)
  • McLean Bottom Levee and Pumping Station (USACE operated and maintained)

Levee overtopping resulted in one breach and three slides, as well as extensive damage to the vegetation on the levee.

Current Action:  Repairs to breach at 5th Street and adjacent slide continue, design for other damaged areas continue.

Next Steps:

  1. Complete repairs to breach at 5th Street and adjacent slide.
  2. Continue design for other damaged areas.

  4. Monitor levee during the 2020 flood season.
