So much water is heading down the Mississippi River that the U.S. Army Corps of Engineers announced Monday that it will open the Bonnet Carre Spillway, located about 12 miles upriver from New Orleans, later this week. This will divert some of the river's water into Lake Pontchartrain in southeastern Louisiana, which will keep the New Orleans levees from being further stressed, according to the Associated Press.

This will be the first time in the 88 years of the spillway's existence that it needed to be opened in consecutive years, and only the 13th time it has been opened at all, the report added.

Here's how the prolonged flooding has affected other parts of the South.

Tennessee

Knox County Commissioner Larsen Jay told the News Sentinel the flooding was "the most water I've seen in my 25 years in and around Knoxville."

"What I saw was just massive areas of flooding in all areas of town," Jay said. "There were no areas of Knoxville that weren't affected."

The Knoxville County Sheriff's Office said a man was found trapped inside a submerged vehicle early Sunday. Rescuers freed the man and took him to a hospital where he was pronounced dead, the sheriff said. He was identified as Christopher J. Doody, 59, of Knoxville, the Knoxville News Sentinel reported.

Also Sunday morning, part of State Road 66 in Hawkins County, Tennessee, was completely washed away. The county's 911 dispatch confirmed to WJHL that the road is "not there anymore." It was the second landslide this week in the county, which is about 50 miles northeast of Knoxville.

On Thursday, a landslide took out both lanes of State Road 70. One person died in that slide.

Interstate 24 was closed north of Nashville on Sunday after a cliff face collapsed, pushing mud and rocks into the eastbound lanes , WTVF reported. A state Transportation Department official said the road could be closed for a week or more.

In the Chattanooga area, a landslide completely destroyed a Signal Mountain Subway restaurant, the city's fire department tweeted Saturday. No one was in the restaurant when the landslide occurred. Police also evacuated the adjacent Shuford's BBQ restaurant.

A teenage boy also is missing days after the vehicle he was riding in was swept off a bridge by floodwaters from a creek at Bucks Pocket State Park.

Northeast of Birmingham, two Cherokee County towns — Leesburg and Cedar Bluff — have imposed curfews and told residents to stay off the roads at night, the AP also reported.
