Pee Dee River

The Pee Dee River, also known as the Great Pee Dee River, is a river in the Carolinas of the United States. 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. The river empties into Winyah Bay, and then into the Atlantic Ocean near Georgetown.

The northeastern counties of South Carolina compose the Pee Dee region of the state.

The exposed rock formations along its course are the source of a NIST reference standard.

It is an important source of electric power and public water supplies, as well as recreational use.

While the Pee Dee is free-flowing in South Carolina, upstream in North Carolina, several dams have been constructed on it. The opening and closing of these dams causes dramatic swings in the depth of the river in South Carolina. The sharing of water between the two states has sometimes been a matter of controversy, particularly during periods of drought.

Some commercial fishing is done during the winter shad run, and for shrimp in the lower reaches. The river is excellent for recreational fishing and boating.

There are numerous boat landings, yet most of the river is wild, with forests of tupelo, oak and gum along its shores. Herons and alligators can be seen along the way, and a lucky sighting of a bald eagle is possible.

The lower part of the river from Highway 378 to Winyah Bay has been designated a Scenic River.
