Yankton, S.D. - Repair work is set to begin on the concrete slab below the Gavins Point Dam Spillway this Monday, Nov. 26.

The slab was damaged when record amounts of water were released from the spillway during the Flood of 2011. 

The project will have three objectives: 

  • make repairs to the concrete slab and the gravel frost blanket;
  • conduct additional assessments on the spillway; and
  • remove debris that has been  deposited on the slab.   

Work on the project is expected to take several months. The project will be staged at the parking lot located on the north side of the spillway, also known as the Fishing Wall parking area.  As a result, the parking area will be closed to the public 24-hours a day until the work is complete.

In addition, the Training Dike Boat Ramp, located just downstream of the spillway, will be closed Friday, Nov. 30 and Saturday, Dec. 1 for barge staging in preparation of the slab repairs.
