Copan Dam is a dam in Washington County, Oklahoma, in the northeastern part of the state.
Construction of the earthen dam began in 1972 and was completed in 1983 by the United States Army Corps of Engineers, with a height of 73 feet (22Â m) and a length of 7,730 feet (2,360Â m) long at its crest. It impounds Little Caney River for flood control and municipal drinking water. The dam is owned and operated by the Corps of Engineers.
The reservoir it creates, Copan Lake, has a water surface of 7.6 square miles (20Â km2), has a maximum capacity of 338,000 acre feet (417,000,000Â m3), and normal capacity of 43,400 acre feet (53,500,000Â m3).
Copan Wildlife Area is a wildlife management area that was leased to the Kansas Department of Wildlife and Parks from the Corps of Engineers in 1981. The wildlife area is part of an overall project with the Copan Reservoir, located in Oklahoma. It covers 2,360 acres (9,600,000Â m2) in Montgomery County, Kansas.

Copan Lake and Dam - More water in this lake than we've ever seen before. We were only there about 20 minutes which was about 19 minutes longer than I wanted to be!
