The Lumber River, also known as the Lumbee River, is located in south-central North Carolina in the flat Coastal Plain. The river's headwaters are known as Drowning Creek, and the waterway known as the Lumber River extends downstream from the Scotland County-Hoke County border to the North Carolina-South Carolina border. Soon after crossing into South Carolina, the Lumber River flows into the Little Pee Dee River, which then flows into the Pee Dee River, or Great Pee Dee River, from there into Winyah Bay, and finally into the Atlantic Ocean.
