RedactedNarrative: On 6/18/2016 at approximately 2330, units 1 and 2 collided on Lake Keowee near the mouth of Kelly Creek and the dam.  The operator of Unit 1 stated he had been fishing at the hot hole area near the dam and was coming from the Canal Bridge area towards Gap Hill.  The operator of Unit 2 was coming from the mouth of Kelly Creek towards the Canal Bridge when the two vessels collided.  At 2344 on June 18, 2016 Officer2 called me (Officer1) and stated that we had a boating accident with injuries on Lake Keowee.  Officer2 was still out patrolling Lake Keowee and went to Gap Hill Landing where the occupants of Unit 1 were because the vessel was sinking.  He took statements from the two occupants, Operator1 and Passenger1, who were on board the bass boat and took pictures of the boat.  Officer2 informed me that the bass boat had damage to the hull at the bow of the boat and that was the primary point of impact on the bass boat.  Operator1 stated that he was coming from the Canal Bridge toward Gap Hill.  He said they were running between 30 and 35 mph when he heard Passenger1 say there was a boat right in front of them so he cut hard left.  At this time he struck Unit 2 near their stern and proceeded to slide down the side of the pontoon before coming to a stop.  Passenger1 provided the same information in his statement.
  
  Officer2 gave me the contact information for the owner of Unit 2 and also the grandfather of two of the victims and informed me that the victims were being transported in a personal vehicle to Cannon Memorial Hospital in Pickens, SC.  I made contact with the grandfather upon reaching Cannon Hospital and he informed me that the victims were en route and we made plans for myself and Officer2 to come and look at his pontoon boat on 6/19/16.  I made contact with the 4 victims:  Operator2, Occupant1, Occupant2, and Occupant3 and the parents of Operator2 and Occupant1 at the hospital.  I took statements from the four victims prior to them receiving treatment.  Occupant1, Occupant2, and Occupant3 were all holding ice bags to their heads and Occupant3 had a laceration on her right ear upon arriving at the hospital.  The three girls were treated that morning at the hospital.  They each received CT scans of their heads.  Occupant3 received an x-ray of her left knee and seven stitches to her right ear.  They did not receive results from their CT scans that morning and had not received word from the hospital when Officer2 and I arrived to evaluate the pontoon later that day and have not received word from the hospital as of yet.  Operator2 received medical treatment on 6/21/16 at Gwinnett Medical Center in Duluth, GA.  He was referred to their concussion clinic and told he had a sprained right knee and ankle and to just keep ice on it.
  
  After the collision Operator2 was able to navigate the boat back to his grandfather's dock in Kelly Creek. The three girls all gave very similar statements about the accident stating they were unaware of the boat prior to getting struck by Unit 1.  Operator2 stated that he saw Unit 1 at the last minute and attempted to avoid them by cutting the pontoon hard right.  When myself and Officer2 inspected the boat on 6/19/16 we were able to corroborate the statements that were given.  The initial point of impact on Unit 2 was approximately 3 feet from the stern on the port side.  The railing, benches, tables, and chairs that were on the port side were in various pieces and positions on the deck.
