Lake Secession is a 1,450-acre reservoir located in Abbeville County, South Carolina, approximately 18 miles southwest of Anderson. The lake, which impounds the Rocky River, extends about 6 miles and has 52.28 miles of shoreline. Built in 1939-1940 as a WPA project, it is owned and managed by the City of Abbeville primarily for municipal power production.

Paddlers should be aware that Lake Secession has many tree stumps protruding from the water, particularly in coves and the upper reaches where the river enters. The lake is more riverine in character, only widening near the dam. These features, combined with standing timber in some areas, require caution when navigating.

Access is available via a double boat ramp on Highway 184 near Iva, South Carolina. This public access point, provided by the City of Abbeville, is free to use. Some lakeside businesses also offer boat ramps for a fee.

Lake Secession is known for its excellent fishing opportunities, which may interest paddlers. The lake supports populations of largemouth bass, black crappie, catfish, bream, and seasonally, white bass. The Highway 184 bridge, the only one crossing the lake, features rip-rap banks that attract fish and anglers alike.

Water conditions can vary significantly with rainfall, turning muddy brown for several days after heavy precipitation. On windy days, the lake's smaller size makes it suitable for boats that might struggle with larger reservoir waves.

The lake's fertile nature supports a diverse ecosystem, potentially offering wildlife viewing opportunities for paddlers. Development around the lake is primarily residential with some businesses, maintaining a relatively natural setting.

No specific paddling restrictions are mentioned, but a South Carolina fishing license is required for anglers. The lake has no boat motor restrictions, so paddlers should be prepared to share the water with powered craft.
