RedactedNarrative: On Wednesday, June 23rd 2021, I was dispatched to Four Seasons Marina at approximately 1640 in response to a single vessel accident with one injury. I arrived on scene at 1721, as the injured party was being transported by EMS to the landing site to be transported to SkyLine Medical for injuries. Upon speaking with OPERATOR 1 and investigating the accident scene, OPERATOR 1 was operating a 24 ft Southbay pontoon vessel downstream from Pine Creek on Center Hill Lake. She was towing two individuals on a tube and had four individuals on board the vessel. She states she was not paying attention to the lake and the direction she was traveling, instead was watching the occupants being towed and on board. She ran the pontoon boat aground going approximately 20 mph. Upon striking the bank, OPERATOR 1 struck multiple tree limbs. She suffered lacerations to the head and neck area, as well as a broke right wrist and dislocated right shoulder. No one else on board the vessel suffered any injuries. After the accident occurred, fishermen assisted the occupants, loaded them onto their vessels, and transported them to Four Seasons Marina. OPERATOR 1 was admitted to Skyline Medical, treated for her injuries, and released. Not maintaining a proper lookout is the leading cause to this accident.
