Water is flowing down the Long Bypass Reach of the Catawba River in Chester County, S.C. for the first time since 1907, bringing life and voice back to the rolling granite waves that are the historic “Great Falls” of South Carolina. Officials celebrated the completion of the multi-million-dollar Great Falls-Dearborn Diversion Bypass project that has returned water to the Catawba’s 2.25-mile Long Reach for new recreational opportunities and to restore aquatic life and lowland habitat. The area will be open to public for paddling March 18..
The project’s 400-foot Main Channel directs most of the flow down 12 feet of drop from the reservoir to the bottom pool. It incorporates three innovative multi-stage drop structures optimized for safe passage and easy surfing at base flows, creating larger, more powerful whitewater features at release flows. The 1,075-foot Recreation Bypass Channel (known locally as “the paperclip”) is a narrow, winding channel that features nine drop structures that control the rate and intensity of flows through the channel, a recovery pool, an island with gradually sloped sides, and portage trails for boaters to exit the channel if needed. The access channel’s design also incorporates special formations to prevent fish from being trapped at lower flows. This project was spawned from Duke Energy’s FERC requirements when relicensing the Catawba-Wateree Hydro Project and is part of the utility’s ongoing efforts to further open local lakes and rivers to recreational use. “This was an innovative approach to a complex challenge, and our team, including Duke Energy and the engineering firm, has done an outstanding job of navigating the numerous engineering, construction, environmental, and regulatory variables,” said Shipley, stressing that while the features in both channels provide opportunities for playing and surfing, this is considered a flow release project and not a traditional whitewater park. S2O Design commends American Whitewater, which represented paddling interests across the basin during the FERC relicensing process and was responsible for spearheading the effort to open up this reach of the Catawba River to boating.
