A 15-year-old metropolitan Atlanta girl was airlifted in critical condition to Grady Memorial Hospital Sunday afternoon after being hit by a boat near Nix Bridge Park.

The teen and two others were being pulled behind a boat on an inner tube about 4 p.m. when she was thrown off and hit by a pontoon boat as the family celebrated Father’s Day on Lake Lanier. The victim’s name has not been released.

Sgt. Mike Burgamy, with the Georgia Department of Natural Resources Law Enforcement Division, said Monday he did not expect to see charges filed in the case.

"The pontoon boat took evasive action and swerved to miss the first girl that fell off," Burgamy said. "He just didn’t see the second girl."

DNR impounded the pontoon boat as part of the ongoing investigation.

"We see this as a very unfortunate accident," said Burgamy, who added there was no alcohol involved in the collision.

Dawson County Emergency Services Battalion Chief Milton Keller said the victim was treated for severe lacerations to the head at the park before being flown to Grady’s trauma unit.

"It took the flight crew about 11 minutes to get to the scene and land from Gainesville," Keller said. "They were very complimentary of the treatment the Dawson County crew had given to the girl before they arrived."

Brian Richardson has lived in the Nix Bridge area for about 20 years and said Sunday’s boat wreck was the first he has seen in the cove, which he describes as "a small and pretty congested area of the Chestatee River."

"There is kind of a blind curve or corner," he said.

As of Monday, the teen remained in critical condition, Burgamy said.
