Also known as the Lower Pee Dee Basin, we refer to it as the greater Winyah Bay watershed because all rivers ultimately discharge into the Winyah Bay estuary near Georgetown, SC. The greater Winyah Bay watershed includes the following river basins: Waccamaw, Lumber, Little Pee Dee, Pee Dee, Lynches, Black.
The rivers of the greater Winyah Bay watershed have played a major role in the history of the region through which they flow, and continue to play a role in the lives of many North and South Carolinians. These rivers support recreational fishing and other water sports, provide drinking water, support tourism, and enhance the lives of those who live here.
Further information on the SC portion of the Lower Pee Dee Basin is available at: SC Watershed Atlas or by clicking the image below.
The Waccamaw has its headwaters in the Lake Waccamaw area of North Carolina. It is considered a blackwater river because of its dark coloration caused by pigments, such as tannins, that have leached out of vegetation growing in the extensive wetlands adjoining the river. The Waccamaw joins with the Atlantic Intracoastal Waterway near Bucksport. The Pee Dee River joins the Waccamaw just before it empties into the Winyah Bay. The Waccamaw River extends more than 140 miles from Lake Waccamaw, a permanently inundated Carolina Bay, to the ocean, draining an area of 1,640 square miles of coastal plain within two states. 100 miles in South Carolina are designated a National Water Trail.
Lumber-Little Pee Dee Rivers
The Lumber River begins at the headwaters known as Drowning Creek, in the counties of Moore and Montgomery, in the Sandhills ecoregion of North Carolina. The main stem of the Lumber River lies in the Coastal Plain ecoregion and is home to the Lumber River State Park. A total of 115 miles of the Lumber River is designated state Natural and Scenic River and 81 miles have also been designated as a National Wild and Scenic River. The river crosses the South Carolina border downstream of Fair Bluff, NC.
Just past the border, the Lumber River joins the Little Pee Dee River. The Little Pee Dee River is a 116-mile-long tributary of the Pee Dee River. The Little Pee Dee technically arises near Laurinburg, North Carolina as Gum Swamp, which flows southward, receiving several small tributaries, across the South Carolina border into Red Bluff Lake, near McColl, South Carolina, then flows to the Pee Dee River and eventually drains to Winyah Bay. The Little Pee Dee River has two segments designated by the state of South Carolina as a scenic river: 14 river miles upstream of its confluence with the Great Pee Dee River; and 48 miles in Dillon County.
Pee Dee River
The Pee Dee River is part of the Yadkin-Pee Dee River Basin, starting as the Yadkin River in the Blue Ridge Mountains and flowing for approximately 200 miles before it becomes known as the Pee Dee River, then another approximately 230 miles southeastward into South Carolina where it becomes known as the Great Pee Dee River, into which the Little Pee Dee River flows, and eventually joining the Waccamaw River before draining into Winyah Bay. The portion within the greater Winyah Bay watershed begins immediately downstream of Blewett Falls Lake in North Carolina, flowing to Winyah Bay and including the Sampit River. The lower Pee Dee is navigable for about 90 miles and its lower 70 mile segment is designated by the state of South Carolina as a scenic river.
With its headwaters in NC, it flows for ~175 miles southeasterly until its confluence with the Great Pee Dee River near Johnsonville, SC. Along the way, it passes through pine uplands, farms and deep swamp forests. Two sections totaling ~111 miles have been designated a South Carolina State Scenic River and offer myriad paddling and recreational opportunities.
The Black River is a free flowing blackwater river, traveling 151 miles before merging with the Great Pee Dee River in Georgetown County. 75 miles of the Black River are designated by the state of South Carolina as a scenic river. The Black River Basin(hydrologic unit 03040205) is located in Kershaw, Lee, Sumter, Clarendon, Florence, Williamsburg, and Georgetown Counties, and encompasses 2,061 square miles with geographic regions extending from the Sandhills to the Upper and Lower Coastal Plains and into the Coastal Zone.
