Rising Mississippi River could force unprecedented second spillway opening: report

in #nature6 years ago

Just two days after announcing that some bays along the Bonnet Carre Spillway will close, the Army Corps of Engineers warned of a second opening, according to the St. Charles Herald-Guide. There is no such precedent.

"That would be historic because it's never happened twice in one year," said Matt Roe of the corps.

The spillway was opened March 8 to avert flooding river downstream in New Orleans as the Mississippi swelled with heavy rain from the Ohio River Valley. Now snow melt farther north could cause a second opening.

One upside? High water is great for freshwater fishing of catfish and bass, and crawfish thrive during floods.

Sort:  

From what I read, they should leave the spillway partially open all year long, decreasing the salinity in the Lake.

The river is dangerously high at the moment... I agree that the Spillway should be left open for a longer period of time. It was a waste of resources to close it and reopen it....

Agreed!
