Lake Edgar Brown is a 100-acre impoundment located in Barnwell County, South Carolina. The lake features a boat ramp and is accessible via Wellington Road, approximately half a mile north of Barnwell off Highway 3. The lake spans both sides of Wellington Road.

Boating regulations limit motor use to outboard engines rated at 10 horsepower or less north of Wellington Road. The lake is open for general activities from 30 minutes before sunrise until 30 minutes after sunset, though fishing is permitted 24 hours a day.

As of 2025, the lake will feature new kayaking facilities at Kilkenny Park through a joint city-county initiative. The project includes the installation of a storage facility housing four 10-foot kayaks with associated paddles and life vests, along with a concrete pad and dedicated lake access ramp for paddlers.

The lake supports multiple recreational uses, including fishing, boating, and water skiing in designated areas. Anglers frequently target largemouth bass, bluegill, shell-cracker, and catfish. The presence of other water activities means paddlers should maintain awareness of motorized boat traffic where permitted.

Facilities include a handicap-accessible fishing pier and boat ramp. The lake's location near the town of Barnwell (33.254°N, -81.368°W) makes it easily accessible for day trips. Current development projects suggest growing recreational opportunities for paddlers in this public access lake.

For safety and regulation compliance, paddlers should note that while fishing is permitted around the clock, all other activities, including paddling, must take place during daylight hours within the specified time restrictions.
