According to the Walker Police Department, the caskets had floated up from the St. Mark's Cemetery in Baton Rouge Friday afternoon as a result of the flooding.
Some residents spotted caskets drifting, while others saw entire burial vaults in the floodwaters.
After the police department shared the eerie image on their Facebook page, those with relatives buried in the cemetery spoke out to share their concern.
"I have family buried here," one person commented. "It is so sad."
Another wrote: "My daddy's wife is buried here. I feel so sorry for her children."
Parts of Louisiana have seen as much as 17 inches of rain over the past weekend, the Associated Press reported.
One man scrambled to rescue nearly a dozen dogs in his car before searching for shelter from the floods.
"It was two inches when I left this morning," the man could be heard saying in footage by WAFB, "it's now about three feet in my house."
After the historic flood left five people dead, and at least 10,000 people in shelters since the rainfall began Friday night, President Obama has declared a state of emergency in Louisiana.
