Oconee County is the westernmost county in the U.S. state of South Carolina. As of the 2010 census, the population was 74,273. Its county seat is Walhalla and its largest city is Seneca. Oconee County is included in the Seneca, SC Micropolitan Statistical Area, which is also included in the Greenville-Spartanburg-Anderson, SC Combined Statistical Area. South Carolina Highway 11, the Cherokee Foothills National Scenic Highway, begins in southern Oconee County at Interstate Highway 85 at the Georgia state line.
Oconee County was named after an historic Cherokee town and the word "Ae-quo-nee", meaning "land beside the water." Oconee (Cherokee: ᎤᏊᏄ, romanized: Uquunu) town developed along the Tugaloo River, the border between present-day South Carolina and Georgia. The town was located along the Cherokee trading path of the early 18th century between the English colonial Atlantic port of Charleston and the Mississippi River to the west.
Oconee Town developed around an ancient platform mound built by ancestral peoples during the period of the Southern Appalachian Mississippian culture, approximately 1000CE to 1500CE. In their public architecture, the historic Cherokee built a communal town house on top of the existing earthwork mound. The town house was a meeting place for the larger community and council. Through the centuries of their long occupancy, the Cherokee would replace the town house, and maintain and add to the mound, building in distinctly colored layers of earth that are visible to archeologists.
Due to its geographic position, the town was at the intersection of the trading path and the Cherokee treaty boundary of 1777. In 1792, the newly formed South Carolina State Militia built a frontier outpost near the town site, and named it Oconee Station.
European-American settlement in this far western area of the colony did not begin until the late eighteenth century. Most did not take place until decades after the American Revolutionary War. South Carolina jurisdictions were successively called parishes, counties, judicial districts and counties again. Oconee County was not created until 1868, after the American Civil War and during the Reconstruction era. It was taken from part of the Pickens District and named after Oconee Town.
According to the U.S. Census Bureau, the county has a total area of 674 square miles (1,750 km2), of which 626 square miles (1,620 km2) is land and 47 square miles (120 km2) (7.0%) is water. Three large man-made lakes provide residents with sport fishing, water skiing, and sailing as well as hydroelectric power. The largest lake is Lake Hartwell, built by the U.S. Army Corps of Engineers between 1955 and 1963. Lake Keowee is the second-largest lake and the Oconee Nuclear Station operates by the lake. Lake Jocassee is the third-largest and is a source of hydroelectric energy, but is also popular for its scenery and numerous waterfalls.
Bad Creek Reservoir, located in the mountains above Jocassee, is lso used for generating electricity during peak hours. The water level can fall by tens of feet per hour and, during off-peak times, water is pumped back into the lake for the next peak period. Because of the dramatic changes in water level due to these uses, boating and swimming are prohibited in this reservoir.
Oconee County is in the Savannah River basin.
