Lake Oconee, Recreational lake in Georgia, United States.

Lake Oconee is a reservoir on the Oconee River in central Georgia, formed where the Oconee and Apalachee rivers meet. It covers 19,971 acres (8,082 ha) and has 374 miles (602 km) of shoreline running through Morgan, Greene and Putnam counties. Wallace Dam, a long concrete structure with spillway bays, a walkway and a pale tower at its right end, separates it from Lake Sinclair.

Georgia Power began building the Wallace Dam on the Oconee River in 1971 and finished in 1979, when the first turbine of the linked hydroelectric plant started running and the reservoir filled. The lake lies just upstream of Lake Sinclair, a sister reservoir the same company created in the mid-1950s. The dam separates the two lakes.

The name comes from the Oconee River and refers to the Muskhogean language spoken by native inhabitants who originally lived in the area. Today the lake attracts anglers pursuing bass and catfish, alongside water sports enthusiasts who sail or water-ski across its open stretches.

Access is available through public ramps and private marinas, with fishing licenses sold at regional shops. Weekends and holidays bring heavier boat traffic, so early mornings remain calmer for fishing or kayaking.

The deepest water sits directly below the Wallace Dam and reaches more than 200 feet (61 meters), keeping temperatures cool there even during summer heat. This depth draws divers who explore sunken tree stumps and submerged structures from the pre-flooding era.
