Confluence Of Bayous

Thibodaux, Lafourche County · Louisiana
Erected 1992

The bayou here was once a river's outlet. Bayou Lafourche began as a natural distributary of the Mississippi, and its earliest name was the Chetimachas River, after the Chitimacha people. In 1904 a dam at Donaldsonville sealed it off, starving the wetlands of sediment and fresh water and leaving a stagnant ditch. A pumping station at the river, built in 1950, restored the flow, and roughly 300,000 Louisianans now drink from it. People call it the longest Main Street in the world, with Thibodaux strung along it between Labadieville and Raceland.
