Pensacola Dam was the first hydroelectric facility constructed in Oklahoma. GRDA built the dam between December 30, 1938, and March 21, 1940, when depression-era labor was abundant. It is located between the communities of Langley and Disney, spanning a mile across the Grand River Valley and holding back the 43,500 acres of water that form Grand Lake O’ the Cherokees.
