Caddo Lake

Oil City, Caddo County · Louisiana

How the lake got here is still argued. Most geologists think the Great Raft, a 100-mile log jam on the Red River, flooded a low basin gradually or suddenly, and timber from a federal survey of 1913 and 1914 suggests it formed around 1770 to 1780. Wikipedia reports a Caddo legend crediting the 1811 and 1812 New Madrid earthquakes, plausible because Reelfoot Lake formed that way, though geologists generally favor an earlier date. Clearing the raft lowered the water by more than ten feet and ended riverboat trade on the lake.
