The search for a missing boater on the Chattahoochee River in Gwinnett County will resume this morning, said Capt. Tommy Rutledge, spokesman for the Gwinnett County Fire Department.

Rescue efforts, which were suspended Sunday evening, have been turned over to the Georgia Department of Natural Resources.

On Sunday, Gwinnett firefighters responded to a report of a capsized boat on the Chattahoochee River just south of McGinnis Ferry Road in Suwanee.

The men were in a small aluminum jon boat and were not wearing life jackets, according to a witness.

The boat reportedly struck a log in the river, causing it to overturn, Rutledge said.

The boat drifted for about 10 minutes when a second boater on the water encountered the capsized boat.

The second boater told authorities the current had separated the two men, with one clinging to the overturned boat and other in the middle of the water across the river, Rutledge said.

The witness was able to rescue the man in the middle of the river, but as he trying to reach the second man, the boat went underwater, taking the man with it.

That was the last contact that he had with the missing boater, Rutledge said.

The rescued man was taken to Gwinnett Medical Center in Duluth. He had no obvious injuries and his condition was not life threatening.

A later search effort included Forsyth County and Johns Creek fire departments and DNR.

Authorities aren’t releasing the missing man’s name yet, saying only that he in his late 50s.

Water generated from Buford Dam was stopped at about 11:10 a.m.
