ATLANTA - Authorities say a man last seen stranded on an island in the Chattahoochee River has been found alive hours after crews rescued other people he was with.
Officials tell Channel 2 Action News that five people were stranded on an island area of the river Monday night. Crews rescued four people and searched for a fifth, described as an adult male in his 20s.
Authorities say the man showed up at his house in Gwinnett County around 4 a.m. Tuesday.
Emergency crews from Fulton County, Gwinnett County, Johns Creek and Roswell worked the rescue the Chattahoochee Recreational Area off Barnwell Road in Johns Creek.
Johns Creek Fire Chief Jeff Hogan says four men and one woman had been walking and swimming in the area. Shortly before 9 p.m. they were on an island in the river and realized the water was starting to rise. As they attempted to make it to shore, one man was washed downstream.
Gwinnett County Fire Capt. Tommy Rutledge says water was released from the Buford Dam not long before the man disappeared.
Rutledge says the water level can rise from 6 to 11 feet during that release. They're not sure if this is what caused the disappearance, but say it would have created conditions to sweep the man away.
Several agencies had boats out on the water using sonar technology and a helicopter using infrared as they searched for the missing person.
Hogan says the water temperature is between 47 and 52 degrees, and hypothermia was a concern.
