RedactedNarrative: On 05-05-2017 at approximately 1200 hours, I responded to Palisades Reservoir in Bonneville County Idaho. We were dispatched to a possible boat crash near the Indian Creek boat launch. Witnesses had said that they found a lot of debris near the shore line and a dog that was alone. Witnesses described the items as personal belongings that could have been on a boat. While responding to the scene another witness called 911 saying they had found 2 male bodies floating in the water near Big Elk creek on the reservoir with life jackets on. At this time several boats were called to assist in locating the victims and any other possible wreckage or victims. I responded to Calamity boat dock with a small boat. Current estimates of the reservoir capacity was 8% full and calamity was the only boat ramp that was accessible. Another Deputy had launched a boat prior to my arrival and confirmed that there was a third female victim located in close proximity of the other 2 males. GPS coordinates were documented of all three victims along with water temperature.  The area where the victims were located is known as Van point.
  
  All three victims were wearing life jackets and. The two males were tethered together and the female was alone. The first Victim was wearing a type 3 PFD and the other male tethered to him was subject2 and he was wearing a type 2 PFD. Both males had no apparent injuries and were fully clothed. The female victim  was wearing a type 2 PFD and was also fully clothed. Subject3 had apparent head trauma to the forehead area. It is unknown what caused the trauma at this time. All three victims were removed from the water and transported to Calamity Boat ramp. The County Corner was notified and he responded as well. Woods Funeral home was also notified as the next non-preference funeral home provider.
  
  Once the victims were secured on shore, we began to search the shore lines for any other victims and possible crash location. A searcher on the shore had located a floating orange object approx. 300 yards from shore between the Blowout boat ramp and Indian Creek boat ramp on the east shore. I responded to the area and located a faded orange gas tank that appeared to be anchored to something along with a blue rope. The depth of water in that area was 11.5 feet and the water temperature was 48.3 degrees F. The GPS location 43 degrees was 15’ 25.2”, -111 degrees 07’41.0” and began to investigate. We located a white rope attached to the blue rope that was connected to small boat. As we began to pull the boat from the bottom, we located an anchor attached to the white line. The boat, light blue in color with hull #WN4743NW registered out of the state of Washington. We were able to completely remove the boat from the water. A Honda outboard motor was attached to the boat which was attached to the faded orange gas tank. The boat was a 1982 Ottawa brand boat, 16 feet in length. 
  
  The registration showed subject as the owner of the boat. Numerous pictures were taken of the boat as we removed it. There was no apparent damage to the hull of the boat. There was no obvious signs of damage anywhere on the boat and the motor was in neutral gear. All the parts of the boat were loaded into our boat and taken to Calamity boat dock. No other debris or parts were located. We were also were able to confirm from the victim’s friends that there was only three occupants on the boat along with gear and a dog. 
  
  The process of notifying next of kin has begun and at the time of this report all the families have not been notified. The boat and the vehicle was towed by Majestic Towing to the Bonneville County Jail impound for safe keeping. The Coroner said that the victims would be autopsied to confirm cause of death. The Coroner also guessed the time of death to be the night before. I believe the accident was caused by the boat being overloaded, and overpowered, which caused it to take on water, capsize and then sink placing all persons into the 48 degree water which ultimately lead to their deaths.
  
  All pictures and GPS locations have been attached to the report. An IDPR Boat crash form has been completed and the IDPR staff was notified. 
  I have nothing further to report at this time.
