The Pensacola Dam, also known as the Grand River Dam, is a multiple-arch buttress dam located between the towns of Disney and Langley on the Grand River in Mayes County, Oklahoma. The dam is operated by the Grand River Dam Authority and creates Grand Lake o' the Cherokees. After decades of vision and planning, it was constructed between 1938 and 1940 for the purposes of hydroelectric power generation, flood control and recreation. It is Oklahoma's first hydroelectric power plant and is referred to as the longest multiple-arch dam in the world.[3][4][5]
