RedactedNarrative: On Saturday, July 10th, 2021, I, Game Warden 1, was patrolling Lake Mead by land.  At approximately 1412hrs, I was driving on the Hemenway Launch Ramp when I heard a large concussion from an explosion.  Game Warden 2 was patrolling nearby via a patrol vessel and obviously heard the same concussion and contacted me via radio to respond to the fuel docks at Las Vegas Boat Harbor.  
  
  I drove to the fuel dock headwalk and ran to the vessel that was starting to burn.  I reached out to the bow of V1 and attempted to swing the stern toward the dock to rescue any victims.  V1 started going up in flames.  I, with help from Good Samaritan's and fuel dock workers, attempted to extinguish the flames with fire extinguishers.  I called out and heard voices on the stern of V1.
  
  Game Warden 2 arrived on scene and was attempting to rescue any victims onto his patrol vessel.  I could hear Game Warden 2 calling out to the victims to get off the burning boat and jump into the water.  I called out into the black smoke to any victims to get off the burning boat and jump into the water as well.  The conditions were extreme, and I couldn't see anyone due to the dark thick smoke.  I was looking under the smoke into the water and saw two arms reach up onto the dock.  A Good Samaritan and I pulled the first victim, Operator, out onto the dock.  V1 continued to burn and was taking on water and sinking.  I continued to look for another victim and could see another person in the water below the smoke.  Passenger was clinging to a type IV.  I called out to him to swim toward me.  I reached out and pulled him to the dock, and with help from the Good Samaritan, pulled him up onto the dock.  
  
  Game Warden 2 pushed V1 from the dock with his patrol vessel as it finally sank right off the fuel dock.  As Good Samaritan's tended to the victims, Game Warden 2 pulled his vessel to the dock and took over care on Passenger, applying pressure to his head laceration.  National Park Service (NPS) Rangers arrived and took over as medical.
  
  I obtained my camera and photographed the scene.  I obtained witness statements from two dock employees who observed the explosion.  Both victims were transported to nearby hospitals for their injuries.  Game Warden 2 and I were treated and released from Boulder City Hospital for smoke inhalation.  Officer 3 arrived and took over the scene, photographing and taking information as employees from Las Vegas Boat Harbor pulled the vessel up and onto a trailer.
  
  On July 12, 2021, I met with State Fire Marshal's from the Nevada Department of Public Safety, and they investigated the explosion.  Their initial investigation showed that the cause from the explosion was due to a flammable vapor inside the engine compartment that was ignited from an unknown source causing an explosion.  Their final report is still pending.
