RedactedNarrative: On August 25, 2019 I, US Park Ranger was advised by Bullfrog Clinic staff of a person receiving treatment from a boat accident that occurred earlier that day. I contacted the operator of the vessel in the clinic. He stated to me that him and his family were on their ski boat in the San Juan Arm of Lake Powell when a wind event began to cause large waves where they were located. As a result of the wind and waves, a wake board on the ski rack on the vessel broke loose and struck subject in the head causing a laceration. As a result of the injury, subject received stitches at the Bullfrog Clinic. Operator also stated to me that the wake board tore the vinyl on the rear seat cushion but estimated the damage as under $500.
