RedactedNarrative: INITIAL CALL:
  
  At approximaely 1540 hours on 6/6/15 I overheard NPS Dispatch contact NPS Ranger and inform him that a vessel accident had occurred.  Dispatch stated the involved party and the vessel were now in the RV Camp Loop at Bullfrog.
  
  RESPONSE:
  
  I responded in my patrol vehicle to the RV campground loop and informed NPS Ranger that I would take the accident report. 
  
  INVESTIGATION:
  
  I located the involved vessel near camp site 9.  It had visible damage to the bimini top and exterior of the railings on the pontoon boat.  I contacted the vessel owner, OPERATOR, and asked him to tell me what had happened.  OPERATOR informed me that he and 7 other people were on the boat just down stream from Hall's Crossing and on the opposite side of the channel.  He stated it had been raining and he (operator/owner) decided to seek shelter near the wall of a canyon in that area.  He stated they were watching waterfalls of water cascade over the canyon walls adjacent to them.  At approximately 3:00 p.m. one of those cascading waterfalls began to pour onto OPERATOR's pontoon vessel.  This caused his vessel to tip severely and slam into the canyon wall they were up against.  He stated it took them quite a while to break free from the water and to get away from the wall in the wind.  He stated that besides being shook up, that everybody on board was physically okay.  He stated one male might have injuries to his arms and one female may have broken a finger.
  
  I asked OPERATOR to fill out a witness statement after he changed into dry clothes while I documented the damage to the vessel.  I took photos of the damage to the vessel (attached) and recorded the vessels information.  There was extensive damage to the bimini top, the counter/bar area and the railings of the vessel along with other damage that was documented.  I then began to collect the information of all the passengers who had been on the vessel at the time of the accident with the assistance of NPS Ranger.  NPS Ranger (EMT) interviewed two people who had been reported to possibly have been injured.  Subject1 had scratches/scrapes on his arms from trying to hold the vessel off the canyon wall.  Subject2 had bruising on her hands & wrists from doing the same thing.  Neither desired any medical treatment and both were directed to the location of the Clinic in Bullfrog should they change their mind.
  
  While acquiring information on the passengers on the vessel, a passenger showed me a video on his phone.  The video showed them on the involved vessel near a canyon wall watching waterfalls cascade over the canyon walls into the lake in very close proximity to them.  Passenger stated the video was taken just prior to their accident event.  From the video it was clear to me they had placed the vessel in a very unsafe location given the wind and rain storm conditions at the time.
  
  I received the witness statement from OPERATOR and reviewed it.  All the other passengers gave verbal accounts of the incident that were of the same nature as Operator's statement.  I asked OPERATOR to email me his vessel insurance information when he arrived at home as he did not have it with him. I received that email the following day.  I informed him his insurance company could contact me to get information on how to obtain a copy of his accident report.
  
  CONCLUSION:
  
  Based on the statements of Operator and the other passengers on the vessel I spoke with I believe the following to be an accurate representation of what occurred in this accident.
  
  At approximately 1500 hours on 6/6/15 Operator operated his vessel to a location near Lost Eden Cyn, close to a canyon wall with the intention of staying there under some cliff overhangs to wait out the current rain/wind storm that was passing through the area.  In this location he and other passengers were watching waterfalls cascade over the cliff walls in close proximity to their vessel. I believe that OPERATOR thought this was a safe location du
