Projects include repairing spillway gates, outlet works, scour areas, work recreational facilities, roads and other flood control structures that were damaged during the Missouri River Flood of 2011. The estimated cost of making these repairs totals $234 million.

Six contracts were awarded in 2012 to repair damages at Fort Peck Dam. They include repair of gates, the spillway slab, plunge pool, recreation area roads and drains, the spillway access road and associated drains, rehabilitation of eight emergency gate controls and the repair of relief wells and the horizontal outfall pipes.

The gate repair contractor mobilized and has begun repairs. Installation of relief wells and under seepage control has been completed. The plunge pool repair contractor continues to work on slope excavation on east and west sides of the spillway. Horizontal anchor drilling has begun.

The gate repair is scheduled for completion in early 2015. The plunge pool repair is scheduled for completion in December 2015. All other repairs are scheduled for completion in early 2014.
