The Catawba River flows out of Lake Wylie and is joined by Sugar Creek, Twelvemile Creek, and Cane Creek before draining into Fishing Creek Reservoir. The Catawba River flows out of Fishing Creek Reservoir and joins with Fishing Creek and flows into Great Falls Reservoir. The river then joins with Camp Creek and Rocky Creek to form Cedar Creek Reservoir. Cedar Creek flows into the Catawba River just below the Cedar Creek Reservoir dam. The Catawba River merges with Big Wateree Creek to form the Wateree River Basin.
