Bayou Info

Sometimes described as the “longest Main Street in the world,” Bayou Lafourche stretches some 106 miles connecting communities between Donaldsonville and the Gulf of Mexico. It flows through parts of Ascension, Assumption, and Lafourche parishes. The name Lafourche is from the French for "the fork", and alludes to the bayou's large outflow of Mississippi River water.

The bayou once was a main distributary of the Mississippi River leading to the Gulf of Mexico. In the 1700s, French explorers may have traveled on this waterway as they staked claims in the coastal areas. Original inhabitants of the area include the Chawasha, Washa and Chitimacha tribes. Acadians began arriving from Canada in the mid-18th century and established the fishing and trapping legacy that remains in this heavily Cajun-influenced area today.

Today, approximately 300,000 Louisiana residents drink water drawn from the bayou.
