Army Corps could begin Bonnet Carré Spillway closure in 2-3 weeks

Based on the forecast from the National Weather Service, the spillway should be safe to close in mid-July

The Army Corps of Engineers could begin closing the Bonnet Carré Spillway in two-to-three weeks.

Officials tell Eyewitness News that the closure will begin when the river goes down to 15.5 feet at the Carrollton Gage. Crews will be able to safely begin closing the bays once the river reaches that level.

Based on the forecast from the National Weather Service, that should happen in the second or third week of July.

Army Corps of Engineers officials tell us that the closing will not be a quick operation since there is still a tremendous amount of water in the river.

Unprecedented flooding raised the river level so high that for the first time ever, the Army Corps of Engineers opened the Bonnet Carré spillway twice in one year.

Shrimp landings were down 63% and blue crab landings down 45% in April from the five-year average. There's been a drop in the fish catch, but it hasn't reached the statewide average of 35% needed for a federal fisheries disaster declaration, the report says.
