The structural height of the dam is 122feet.
Fort Cobb Reservoir has a total capacity of 143740acre.ft and covers an area of 5956acres at top of flood pool level. The uncontrolled morning-glory spillway in the left abutment consists of a concrete intake structure, concrete conduit, and concrete chute and stilling basin.
The Fort Cobb Reservoir is part of the Washita Basin Project of the Bureau of Reclamation, which also includes Foss Reservoir on the Washita River in Custer County, along with numerous small flood-control structures on creeks and streams. Municipal and industrial water is supplied to the city of Anadarko and Western Farmers Electric Cooperative through the Anadarko Aqueduct which begins at the Fort Cobb Reservoir.[5]
Fort Cobb Reservoir provides over 2000acres of land and some 2300acres of water surface areas for recreation and includes 1800acres of land and 1800acres of water surface area for wildlife management. This reservoir provides some 450NaN0 of shoreline at top of conservation pool. The recreation areas are administered by the Oklahoma Tourism and Recreation Department and the wildlife management area is administered by the Oklahoma Department of Wildlife Conservation.
