RedactedNarrative: On April 25, 2015 at 1055 hours I was contacted via Butler County Dispatch about a boat that was taking on water in the area North of Bluestem point at El Dorado Reservoir. I was given a contact number to a relative who was also in a boat nearby. I contacted the number and found that all occupants of the boat were fine and were currently loading onto the other boat. I informed them I would meet them at the Shady Creek Marina.
   
  I arrived at the Marina at 1145 hours to meet Operator who informed me he was the owner and operator of the boat. I asked Operator what happened and he stated they were fishing and he was using the small motor to keep steady against the waves while they were fishing. Operator stated he looked back and noticed the back of the boat away from the waves was filling with water. I asked Operator if he had hit anything while on the water and Operator stated he knew about 5 minutes before they had bounced on rocks but didn''t think it was hard enough to damage the boat. Operator stated when he realized he wouldn''t be able to keep the boat afloat, he went around the cove and drove straight to the shore. Operator stated once at the shore or in about 3 to 4 feet of water the boat continued to sink. Operator also mentioned when he fired up the big motor to drive to shore, the nose of the boat went very high in the air indicating the back of the boat was full of water more than he thought. I told Operator we would return to his boat later in the afternoon when the wind died down.
   
  I returned to meet Operator at 1600 hours and we loaded onto my patrol boat and returned to his boat. On approach I could see the boat was resting on the bottom of the lake in about 3 feet of water with the back end submerged and the front higher. I explained to Operator I would not be attempting to tow the boat across the water with the condition it was in as I felt once we got to deeper water it would sink the boat. Operator asked what he needed to do and I told him to talk with his insurance company about recovering the boat because I didn''t have the equipment to do so. Operator proceeded to salvage everything he could from the boat and place it into mine. When we were finished I returned to shore and provided Operator with my phone number and the case number.
  I have nothing more to report at this time.
