Mark Hicks, an investigator with the Cherokee County Sheriffs Office, said Monday, the mans fingerprints have been sent to law enforcement agencies.
The Department of Forensic Sciences in Huntsville has completed its autopsy but has not released the results, Hicks said.
The death is expected to be investigated as suspicious.
Cherokee County Coroner Don Rogers said the body, which was at the bank of the state docks on Alabama Highway 9, was that of a Hispanic or white man. He is about 50 years old with gray hair.
Cherokee Sheriffs Investigator Mark Hicks said a woman called officers about 8:40 a.m. when she saw the body as she walked out on the pier.
Sheriff Jeff Shaver said officers have not found an abandoned boat or vehicle near the docks, but they are checking with nearby counties for missing persons.
The docks are open all night and Cedar Bluff police officers rode around the dock parking lot about midnight Wednesday and did not see anything suspicious, investigators said.
Police do not think the body traveled far because wind on the lake Wednesday night was between zero and 5 miles per hour, Shaver said.
The lakes power generators ran about 10 p.m. Wednesday and had not run again until the body was discovered.
Investigators pulled a blanket from the lake near where the body was discovered.
Several law agencies are involved in the investigation including Cedar Bluff police, the Sheriffs Office, Centre police, the Alabama Bureau of Investigation, Marine Police Officer Rick Sides, the state forensics team from Jacksonville and the Cherokee County Rescue Squad
