Pee Dee Rivers
The Pee Dee River, also known as the Great Pee Dee River, is a river in North Carolina and South Carolina. It originates in the Appalachian Mountains in North Carolina, where its upper course, above the mouth of the Uwharrie River is known as the Yadkin River. It is extensively dammed for flood control and hydroelectric power. The lower part of the river is named Pee Dee (in colonial times written Pedee) after the Native American Pee Dee tribe. The Pee Dee region of South Carolina, composed of the northeastern counties of the state, was named after the tribe and/or river. The first Europeans believed to have navigated part of the river was a party sent by Lucas Vázquez de Ayllón in 1521.
