Lake Blackshear, Reservoir in southwest Georgia, United States

Lake Blackshear is a man-made reservoir on the Flint River in southwest Georgia, about 20 miles (32 km) long and rarely more than one mile wide, covering roughly 8,500 acres. It was formed by the Crisp County Power Dam, also called the Warwick Dam, built from 1925 to 1930. Living cypress trees stand in open water, and submerged stumps remain, especially on the northern half above the Highway 280 bridge.

The lake came into being in the 1920s through construction of a dam by the local power commission. The dam was among the first publicly financed power facilities of its kind in the nation.

The lake is named after General David Blackshear, founder of Fort Early. Georgia Veterans State Park occupies its eastern shore, and the Lake Blackshear Resort & Golf Club sits inside the park, giving visitors a base beside the water.

The area offers fishing access at various spots along the shoreline. A resort with lodging, dining, and golf facilities sits on the eastern shore and serves as a hub for visitors.

When the dam was built, little effort was made to cut the trees that would be submerged, and many living cypress trees still stand in the middle of the lake. Stumps below the water line, mostly on the northern half above the Highway 280 bridge, are popular with some fishermen but risky for recreational boaters.
