RedactedNarrative: Deputy was on duty for the vilas county sheriffs office in marked squad. I was dispatched to a boat accident on long lake where the skier fell and had a possible broken leg. They brought the injured party back to the shore at their residence. Upon my arrival i met with the operator who advised she was towing her father who was slalom skiing behind the boat while she was operating. 
  
  Upon my arrival medical personal was attending to the skier, who was the operators father and the registered owner of the boat. The male was conscious and cooperative. He described that he fell wrong and when he hit the water he broke his leg. 
  
  The skier was transported to eagle river hospital for treatment. 
  
  Operator advised she was not sure if she had boater safety. Dispatch checked and no record was on file. The operator advised she was towing her father and watching him in the wide angle mirror properly attached to the watercraft. She advised she did not see the fall, but noticed he'd fallen down. When she circled around she discovered he sustained an injury from falling into the water while skiing and transported him back to shore. I issued the operator a written warning and advised she needed to complete boater safety and email me a copy of certificate or she was going to be issued a citation if she failed to comply. The operator advised she comes to the state yearly to operate boats.
