Saltwater control structure to be built in Lockport

Saltwater control structure to be built in Lockport

Lafourche Parish officials hope to see construction on a new saltwater control structure along Bayou Lafourche completed next summer in Lockport.

The roughly $3.4 million construction contract with Cayo LLC out of Fort Worth, Texas was awarded at last week’s Parish Council meeting.

The structure, which will be located behind Linda Street in Lockport, is designed to block saltwater from creeping up Bayou Lafourche where it threatens local drinking water supply.

According to the Daily Comet, Lafourche Parish Administrator Archie Chaisson stated, “It’s a pretty big deal for us. It’s going to be a big deal for the water district too.”

Saltwater-control structures work like floodgates, but instead of blocking flood waters, they’re closed temporarily when a canal or bayou is found to be carrying water with too much salinity.

The structures are used throughout Terrebonne and Lafourche to help control saltwater intrusion from the Gulf of Mexico and keep it from destroying interior freshwater swamps and marshes.

Construction involves building new receiving walls in Bayou Lafourche north of the bayou’s intersection with Company Canal.

The steel barge will be taken from the existing Company Canal Saltwater Control Structure, retrofitted slightly and installed at the new structure in Bayou Lafourche.

According to Chiasson, the existing receiving walls will remain in Company Canal.
