A more than $20 million floodgate in Bayou Little Caillou, called the centerpiece of connecting the eastern and western sides of Terrebonne’s Morganza-to-the-Gulf levee, is substantially complete, officials said.

The floodgate, located in the bayou about a half-mile south of Bayou Sale Road in Cocodrie, is 110 feet wide and rises 18 feet above the water.

“We have already declared the floodgate substantially complete. It’s now operational,” Terrebonne Levee District Director Reggie Dupre said.

The project started early last year.

Dupre said this floodgate is different from others because it has flap gates and an electronic pump.

If the water level inside the gate is higher outside, the flap gates will release the water.

“As we’re building these gates, we’re learning from past designs,” Dupre said.

The project also includes a road gate on La. 56, just 4.5 miles from the Gulf to protecdt Cocodrie.

“It’s the first time a state highway crosses Morganza that we have an operational gate,” Dupre said.

There are plans to build an emergency bypass road in case the gate is closed while someone is at their camp during a storm, Dupre said.

Dupre said he expects the road gate to be finished later this month.

The $21 million floodgate is being paid for with a 28-year half-cent sales tax dedicated to the Morganza project.

Morganza is a 72-mile system of levees and floodgates that protect Terrebonne and parts of Lafourche parishes from storm flooding.
