The Project consists of the Jocassee Development and the Keowee Development in Upstate South Carolina and western North Carolina. The FERC license identifies all Project purposes (such as operation and maintenance, flowage, public recreation, public access, protection of environmental resources, and shoreline control) and specifies requirements associated with operation of the Project. The Licensee is responsible for operating and maintaining the Project in accordance with the license requirements and for ensuring Project lands and waters are protected and maintained for their designated Project purposes. Licensees have an ongoing responsibility to supervise and manage shoreline development to ensure it is not inconsistent with Project purposes, including protection and enhancement of the Project’s scenic, recreational, cultural, and other environmental values. This Shoreline Management Plan (SMP) is a comprehensive management tool for managing requests for shoreline activities within the FERC Project Boundary in a manner consistent with Project purposes. This SMP includes the following components: • Shoreline Classification Maps (Appendix A) • Shoreline Classifications and Lake Use Restrictions (Appendix B) • Shoreline Management Guidelines (SMG) (Appendix C), which include the Shoreline Stabilization Technique Selection Process (SSTSP) and the Procedure to Allow Docks to Follow the Water • Shoreline Classification Examples (Appendix D) • Process for Structure Renovation and Removal (Appendix E) • Consultation Record (Appendix F) 1.1 Project Area Description The Project encompasses two reservoirs: Lake Jocassee and Lake Keowee. The Project is located primarily in Oconee and Pickens counties, South Carolina, with a small part of Lake September 1, 2014 1 Shoreline Management Plan Keowee-Toxaway Project (FERC No. 2503) Jocassee extending into Transylvania County, North Carolina. Duke Energy owns all land within the Project Boundary. 1.1.1 Jocassee Development The Jocassee Development is located in Oconee County and Pickens County, South Carolina, and Transylvania County, North Carolina (Figure 1) about 20 miles (mi) north of Seneca, SC. The Jocassee Development consists of a reservoir (Lake Jocassee), dam, two saddle dikes, and a powerhouse. At its Normal Full Pond Elevation of 1,110 feet (ft) above mean sea level (AMSL), Lake Jocassee has a surface area of approximately 7,980 acres (ac) with approximately 92.4 mi of shoreline. The Project Boundary for Lake Jocassee varies from 1,110 ft AMSL to 1,120 ft AMSL, except around Project Access Areas, dams, saddle dikes and the powerhouse where it follows a metes and bounds description. Lake Jocassee has a Critical Reservoir Elevation (also referred to as a “maximum drawdown”) of 30 ft below full pond (i.e., elevation 1,080 ft AMSL). In addition to its hydropower and pumped storage roles for the Keowee-Toxaway Project, Lake Jocassee also serves as the lower reservoir for Duke Energy’s Bad Creek Pumped Storage Project (FERC Project No. 2740). 1.1.2 Keowee Development The Keowee Development is located in Oconee County and Pickens County, South Carolina, on the Keowee River about 8 mi north of Seneca, SC and impounds the Little River and Keowee River. The Keowee Development consists of a reservoir (Lake Keowee), two dams, four saddle dikes, and a powerhouse. At its Normal Full Pond Elevation of 800 ft AMSL, Lake Keowee has a surface area of approximately 17,660 ac with approximately 387.9 mi of shoreline. The Project Boundary for Lake Keowee varies from 800 ft AMSL to 810 ft AMSL, except around Project Access Areas, dams, saddle dikes and the powerhouse where it follows a metes and bounds description. Lake Keowee has a Critical Reservoir Elevation of 794.6 ft AMSL until December 1, 2019, at which time the Critical Reservoir Elevation will change to 790.0 ft AMSL. Lake Keowee also serves as a raw water supply for public water systems operated by Seneca Light and Water and Greenville Water.

Project Location Map September 1, 2014 3 Shoreline Management Plan Keowee-Toxaway Project (FERC No. 2503) 1.2 History of Shoreline Management The development of the previous FERC-approved SMPs for the Jocassee Development and the Keowee Development was greatly influenced by the experience gained in developing and implementing the Catawba-Wateree Hydroelectric Project (FERC No. 2232) SMP over many years. In particular, Duke Energy employed data gathering techniques, a shoreline classification system, terminology, and lake use restrictions for the development of these SMPs, all of which were similar to those used for the Catawba-Wateree SMP. Duke Energy began managing shoreline
