RedactedNarrative: While on vessel patrol at Glen Canyon National Recreation Area at approximately 1615 hours, I received a distress call from dispatch stating a red and white ski boat was taking on water in Bullfrog Bay. The location was not clearly given. UT State Ranger was also on the water and we started looking for the vessel in Bullfrog Bay. Ranger located the vessel just south of the Old Ferry Launch Ramp near East Side of Stanton Creek. The vessel was approx. 50 yards from shore. There were three individuals at the vessel. One male individual was the owner and operator of the vessel. 
  
  The vessel was taking on water, there was approx. 6 inches of water in the vessel on the floor. The vessel was facing the shore line and it was propped on a shallow bed of rocks located 2 or 3 feet under the water surface. Ranger side tied to the vessel and towed the vessel back to the main launch ramp where we assisted putting the vessel back on its trailer before it sank. During the tow OPERATOR'S vessel he used a pump to pump out the water inside the vessel so it would not sink.
  
  I contacted OPERATOR after we got his vessel back to safety. OPERATOR provided me with insurance and registration for the vessel. I conducted a vessel inspection and nothing was noted missing in the vessel. I asked OPERATOR what took place when he got in the accident. OPERATOR stated he was towing a wakeboarder during the accident. He stated that he was traveling approximately 20 MPH. OPERATOR looked back to see if the individual being towed got out of the water. When he looked back forward he noticed a rock sticking out of the water. He was 50 yards from shore. This location in Bullfrog Bay has many rock hazards above and below the surface. The depth of the water goes from 30 ft to 4ft throughout the area. When OPERATOR noticed the rock he swerved toward the shore to avoid the rock hazard. While trying to avoid the rock the vessel struck a submerged rock outcropping. The outdrive broke off and the vessel was sitting on the rocks taking on water. There were no injuries noted from passengers or OPERATOR. Pictures were taken of the vessel and damage was documented.
  
  The vessel had a scratch on the bow side of the vessel. The vessel had three fins underneath and all three had apparent damage from striking the rocks. The outdrive was missing and the bracket holding the outdrive was sheared off. The rudder was bent and the force cracked the fiberglass and bent the rudder back. There were scratches also noted on the bttome of the vessel.
