The Hammonton High School senior, wearing his Civil Air Patrol uniform, told Action News those 90 minutes felt like days.
He was near a broken dam with friends when he put his foot in and got swept away.
"I really didn't know what was about to happen because the water was moving real fast and I felt myself hitting things, I didn't know if I was going to make it out," Reid said.
Firefighters finally reached the teen who was carried away on a stretcher.
Reid suffered minor injuries.
"My God, I know God was with him that day, but I cannot thank enough the rescuers," Kevin's mother Gina Stant said.
A day later, the scene was quieter at the dam but, south of it, dozens of residents are dealing with flood waters.
Atlantic County homes in the Weymouth section of Hamilton Township haven't been flooded, but they are definitely surrounded as the Great Egg Harbor River rises.
"A mess, a huge mess, it's going to be a lot of cleaning up to do," resident Ashley Kline said.
Weekend rainfall north of this area turned the typically slow waterway into a raging river. In Ashley's backyard, the river is supposed to start at stairs, but the flood waters have reached her basement.
She and her family knew the river would rise because Atlantic County sent out a warning, so they tied down the stairs and other furniture and they moved their cars.
"It's not going to recede until tomorrow and now with the rain, not until late tomorrow," Ashley said.
But the Thomas family says it didn't get that warning.
They live across the street from Weymouth Furnace Park which now looks like a lake.
"Our patio furniture already floated away, when I got up at two in the morning, it was already gone," Eliane Thomas shouted across the flood waters to the Action News crew.
While those homeowners are keeping a close eye on the river, Reid doesn't plan to get near one anytime soon.
He admits going near the broken dam may not have been the smartest thing to do.
"No, it wasn't smart at all," Reid said.
