Basin Facts and Figures

The Cooper River Basin encompasses 8 watersheds and 843 square miles. The Cooper River Basin incorporates the Lower Coastal Plain and Coastal Zone regions. Of the half a million acres in the Cooper River Basin, 52.7% is forested land, 15.8% is water, 14.5% is forested wetland, 8.3% is urban land, 4.1% is scrub/shrub land, 2.6% is agricultural land, 1.6% is nonforested wetland, and 0.4% is barren land. The urban land is comprised chiefly of the greater City of Charleston area. There are a total of 471.2 stream miles in the Cooper River Basin, together with 60,188.5 acres of lake waters, and 13,059.3 acres of estuarine areas. The diverted Santee River flows through Lake Moultrie's Pinopolis Dam and joins Wadboo Creek to form the Cooper River. The Cooper River merges with Mepkin Creek to form the West Branch Cooper River, which then converges with the East Branch Cooper River to reform the Cooper River. The Cooper River then accepts drainage from the Back River, Goose Creek, and the Wando River before flowing into the Charleston Harbor and the Atlantic Ocean.   (Source: 1989-90 SPOT Imagery)
