Lockport
Ruins of locks not washed away by a crevasse in 1917 are near here for which Lockport is named. An earlier settlement was named Longueville by 1835 when William Fields donated land for a canal later known as the Company Canal which connected Bayou Terrebonne with New Orleans across the lakes and Bayou Lafourche. After the locks were built in 1850, the name of the settlement changed and the town was incorporated in 1899 as Lockport.
