The 106-mile Bayou Lafourche in southeast Louisiana stretches from the Mississippi River in Donaldsonville to the Gulf of Mexico in southern Lafourche Parish.

Bayou Lafourche is a lifeline to our coastal communities.

• Provides drinking water to 300,000 people in Lafourche, Terrebonne, Assumption, and Ascension Parishes.

• Is a main artery of freshwater and sediment to the fragile coastal marshes of Lafourche and Terrebonne Parishes.

• Serves as the only source of potable water for Port Fourchon and the energy and support companies based there.  Water from Bayou Lafourche is also shipped out in containers for use on offshore drilling rigs and production platforms, servicing 20 percent of America’s energy supply.
