The Congaree River is a short but wide river in South Carolina in the United States; It flows for approximately 53 miles (85 km). The river serves an important role as the final outlet channel for the entire Lower Saluda and Lower Broad watersheds, before merging with the Wateree River just north of Lake Marion to form the Santee River.[1]
Despite the vast bottomland swamp below Columbia, the Congaree is navigable along much of its length at high water by barge traffic. This travels upriver from the Port of Charleston (approximately 100 miles (167 km) away through the Santee-Cooper Lakes to within 5 miles (8 km) of the fall line.
