RedactedNarrative: On 8/14/2017 at 0858 hrs, a passing boater located a pontoon boat (WC #1) that had run aground on Tanglewood Island. He did not see anyone and called 911. The fire brigade, ambulance and county deputies all responded. They located the watercraft's owner. He had left the scene and returned to his cabin across the bay. He was checked over by the ambulance and refused medical treatment and stated his only injury was to his lip from when he went forward into the steering column. 
  
  He stated he had brought a friend over to Muskego Point at approximately 2330 hrs the night before. He was returning across the lake towards his residence. He could see the lights to his boat house but got his bearings off. He drove his pontoon boat at almost full throttle up on Tanglewood Island. His son brought him back to his cabin the night prior. He stated he had not been drinking, nor was he wearing his life jacket. He was the only person on board at the time of the accident. By the time he talked to the deputies, he had already made arrangements to get the pontoon removed. There was some damage to the watercraft.
