RedactedNarrative: While on patrol within the boundaries of Glen Canyon NRA near Rock Creek I was notified of a vessel in distress at Buoy 39. I located the vessel well outside the main channel between the channel marking buoy and the shore. I noticed the back of the vessel seemed higher than the front and it was high centered on a large rock outcropping that was just beneath the surface of the water.
  
  I contacted vessel and identified the operator. I spoke to another subject who had an active warrant out of the Salt Lake area (they did not want to retrieve the individual.) Subject stated he was cruising at normal speed (estimated 10 mph) and was headed down lake Subject stated that he was shaving off the corners and was out of the designated channel and outside the channel marker buoy.  He stated that he struck an underwater island and did not see it until it was too late. Subject stated that he felt the vessel jolt as it ran aground on the left portion and could hear as it scraped "halfway down the pontoon". During subsequent efforts to back off the rock and then run over the rock, Subject hit the port engine on a rock causing the lower unit to bind and discharge oil into the water. The engine was clearly damaged as I looked at it and it would not run. I requested valid insurance and registration for the vessel. Subject acknowledged the vessels registration was expired as confirmed with dispatch, but did have proof of insurance.
  
  Although the houseboat was outside the designated channel, it blocked visibility around the turn and posed a night time boating and navigational hazard. I agreed to attempt to tow the vessel free of the rock and photographed the scene and the vessel. The houseboat was operational and was maneuvering successfully on one engine. There was little wind and the party wished to continue down lake. I issued Subject the above violations and cleared the scene and completed this report.
