The Catawba-Wateree River Basin encompasses 2,322 square miles with geographic regions that extend from the Piedmont to the Sandhills and to the Upper Coastal Plain. The Catawba-Wateree River Basin encompasses some 1.5 million acres of which 3.8% is urban land, 11.8% is agricultural land, 7.3% is scrub/shrub land, 0.4% is barren land, 69.7% is forested land, 3.9% is forested wetland, 0.1% is nonforested wetland, and 3.0% is water. The urban land percentage is comprised chiefly of the City of Rock Hill and to a lesser extent the Camden-Lugoff-Elgin area. The Catawba River crosses the State boundary near Charlotte, North Carolina flowing through Lake Wylie and into Fishing Creek Reservoir, Cedar Creek Reservoir, and Great Falls Reservoir. The Catawba River flows out of Cedar Creek Reservoir and joins Big Wateree Creek to form the Wateree River which flows through Wateree Lake. The Wateree River merges with the Congaree River Basin downstream to form the Santee River Basin.*
