This is a sources sought synopsis for the removal and installation of Gates and Bulkheads for RS Kerr Dam located in Keota, Ok 74941.

Background:

Dam Purpose: Navigation, hydroelectric power, and recreation.

History of Construction: Construction began in April 1964. Closure occurred in October 1970. The lock and dam became operational for navigation in December 1970. Power units 1, 2, 3, and 4 were placed on line on October 5, July 27, September 1, and November 2, 1971, respectively.

Type of Structure: The dam is constructed of rolled earth-filled material. The total length of the structure, including the spillway, powerhouse intake, and navigation lock, is 7,230 feet. The maximum height is 75 feet above the streambed. There is a service road to the right embankment and an access road to the lock in the left embankment.

Spillway & Outlet Works: A gated, concrete, ogee weir type spillway extends partly across the existing river channel and a portion of the right bank between the power improvements and the navigation lock. The spillway weir has a net length of 900 feet and is surmounted by eighteen 50- by 44-foot-high tainter gates. The gates are separated by seventeen 10-foot piers which support a 5-foot-wide service roadway bridge. The spillway has a capacity of 1,542,000 cfs at the maximum pool elevation (19.5 feet above the top of the power pool).

Hydrologic Data: The flood of record occurred in May 1943 with an estimated peak discharge at the dam site of 810,000 cfs
