According to Grove's Chamber of Commerce, the Pensacola dam was "the first hydroelectric facility to be built in Oklahoma." A project that was started during the Great Depression, Pensacola Dam still stands today as a feat of American creation when things are difficult.
The impressive man-made structure holds back 44,000 acres of water and at a quarter of a mile long, is the longest multi-arched dam in the world. If you want to learn about the struggles and successes that people faced during one of the rockiest periods of American history, this is a must-visit.
