At the above date and time I, RFC of the GA Department of Natural Resources, received a call from Cherokee 911 about a boat incident involving a PWC on Lake Allatoona in the area of Field's Landing.  I went to the incident site by truck and met with Deputy from the Cherokee County Sheriff's Office and he informed me of the parties involved.  I spoke with the operator and he said that he and his girlfriend were cruising on the PWC near the no wake markers at the landing.  Operator then said that he made a turn to the left at approximately 35 MPH and passenger fell off the right side of the PWC and then he fell off the left side.  Operator said he called for help and was assisted by a passing boater.  passenger hit the right side of her forehead on an unidentified object causing a laceration approximately 5 inches long.  passenger was transported and treated at Northside Hospital Cherokee.
