RedactedNarrative: Watercraft #1, a PWC, was pulling a 2-person inflatable tube with two juvenile girls sitting upright in a seated position. They were operating near the shoreline and the inflatable tube struck a tree stump that had been sticking out of the water. The tube ruptured on the lower left side and partially deflated. The force of the impact caused both girls to sustain injury. The Owners of the PWC were contacted, got in their pontoon boat and went to the scene in the bay and transported the girls back to shore. They were attended to by first responders on scene, and one girl was transported by ambulance. The other girl was later taken to the emergency room for an evaluation of her injuries. Life jackets were being worn and alcohol was not a factor. There was no damage to the personal watercraft.
