[4] The flooding of the lake forced the community of Bluffton to relocate 5 mi (8.0 km) westward.

The abandoned community was soon inundated; however, a drought in 2011 caused Lake Buchanan's water level to drop significantly, exposing the remains of the town.

[citation needed] Lake Buchanan is a level-controlled reservoir, and will not be allowed to flood during periods of heavy rain.

[citation needed] The Lower Colorado River Authority maintains three parks on the lake: Cedar Point Recreation Area, Black Rock Park, and Canyon of the Eagles.

[6] County parks and private marinas offer boating access to the lake.
