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. The six units at Pensacola Dam have a combined generation capacity of approximately 120 MW. The dam has 21 floodgates on the main spillway and 21 on the east spillways.


Every individual 18 years of age and older must present a valid driver’s license, state issued ID card or International VISA to tour the dam.
