A man pulled from Lake Lanier on Saturday was unresponsive and hospitalized in critical condition after he went under the waters off Buford Dam Park.

Atlanta television reports later indicated he had died, but there was no confirmation from authorities.

The 48-year-old man was visiting the beach area with his family and swam past the designated swimming area before going under and not resurfacing, Gwinnett fire spokesman Capt. Tommy Rutledge reported in a news release.

Crews responded to the 911 call just before 4 p.m. The Gwinnett Fire Swiftwater Rescue Team found the man about 45 minutes later at the bottom of the lake about 50 to 60 feet from shore in about 8 feet of water.

The man was unresponsive and transferred to a nearby hospital in what officials called “a life-threatening condition.”

The victim was not identified and no update on his condition was available Saturday night, according to the Department of Natural Resources Law Enforcement Division.

Hall County Fire Services crews joined responders from Gwinnett and Forsyth counties, DNR rangers and the U.S. Army Corps of Engineers in the rescue effort.

The park is located on the southern tip of Lake Lanier where Hall and Gwinnett counties meet.
