The process of closing the Bonnet Carre Spillway is beginning Friday.
Officials with the Army Corps of Engineers said that crews will close 10 bays Friday and the rest of the spillway’s closure will be gradual based on river levels.
The spillway was opened in February, the first time in history it has been opened in back-to-back years, to alleviate water levels from a rising Mississippi River.
Officials said 206 bays were opened at the spillway.
The river began cresting Wednesday and is expected to sit at the same height until April, officials said. The latest reading at the Carrollton Gage is 16.7 feet.
According to the Army Corps, more than 200 inspection points are being monitored across the district. Officials said they are monitoring 35 seepage points in the metro area.
Additional details were not released.
The opening of the spillway, in St. Charles Parish, is necessitated by one of the wettest winters in the Mississippi flood valley in 100 years.
