Officials said they found a man in his 50's in the South Point subdivision off of Walker South.
They added the man had no obvious signs of trauma, and the area he was found in had five-feet of water in it at one point.
In August 2016, prolonged rainfall in southern parts of the U. state of Louisiana resulted in catastrophic flooding that submerged thousands of houses and businesses.
Louisiana's governor, John Bel Edwards, called the disaster a "historic, unprecedented flooding event" and declared a state of emergency.
Flash flooding swamped a 7-mile (11 km) section of Interstate 12 between Tangipahoa Parish and Baton Rouge, stranding 125 vehicles.
At least 30,000 people were evacuated by local law enforcement, firefighters, the Louisiana National Guard, the Coast Guard and fellow residents, from submerged vehicles and flooded homes.
According to the National Weather Service Hydrometeorological Design Studies Center, the amount of rainfall in the hardest-hit locations had a less than 0.1 percent chance of happening or was a (less than) 1-in-1,000-year event.
indicates that the catastrophic flood in Louisiana was a result of intense precipitation produced by a slow-moving tropical low pressure system interacting with an eastward-traveling baroclinic trough to the north.
Hurricane Katrina, by comparison, dumped about 2.3 trillion gallons of rainwater in the state (though more in other states).
The flood also dumped more water than Hurricane Isaac.
