On a long ridge that once overlooked Deer Creek and its valley, researchers have discovered evidence of a camp of an ancient Indian tribe. The nomads who camped here around 2,000 B.C. were hunters and gatherers and used this camp periodically throughout the year. Since agriculture was not practiced by the nomads, they moved on after they depleted the plant or animal food supplies in a locale. Burial sites near the camp indicate it was inhabited over a period of time.

In more recent years, a cottage owned by Harry M. Daugherty, the attorney general under President Warren G. Harding, overlooked the valley. The rustic one and one-half story cottage was built in 1918. The President was said to have visited this cottage which now bears his name. The completion of the dam in 1968 created the lake with the park officially opening in 1974.
