RedactedNarrative: On July 26, 2015 at approximately 1359 hrs I, Game Warden, was at the Nevada Department of Wildlife (NDOW) Boulder City Office when I was notified by NDOW dispatch of a sunken vessel in WIshing Well Cove at Lake Mead.  NDOW dispatch advised that all the occupants were safe and accounted for and that National Parks Service was requesting NDOW assistance.
  
  I arrived at Wishing Well Cove by vessel at approximately 1502 hrs.  Game Warden was already on scene and the sunken vessel was no longer visible.  The occupants of the vessel were no longer on scene.  I had NDOW dispatch contact the reporting party and was advised that the occupants were at the boat rental shop at Callville Bay Marina.
  
  Game Warden and I arrived at Callville Bay Marina at approximately 1605 hrs.  We were met by an employee with Callville Bay Marina and the 9 occupants of the sunken vessel.  THen occupants stated that they had rented the vessel from Callville Bay Marina earlier that day.  They had been operating the vessel and pulling a tube throughout the morning when they stopped for lunch in Wishing Well Cove.  While drifting with the engine off in the cove the occupants noticed that there was water coming through the floor of the vessel towards the stern of the vessel.  They stated that they attempted to turn on the bilge pump but only a small amount of water appeared to be coming from the outlet for the pump.  They stated that they attempted to start the vessel, but the vessel gauges displayed low battery.  The occupants put on their personal floatation devices.  The occupants unloaded the 5 children and 2 adult women onto a nearby vessel.  the 2 adult make occupants attempted to paddle the vessel to shore, but the vessel sank prior to reaching the shoreline.
  
  I obtained written statements from the adult male occupants.  I advised the representative for Callville Bay Marina that I would need to see the vessel after it was recovered.  I collected the registration information for the vessel from Callville bay Marina.
  
  Game Warden and I cleared from the scene.
  
  On July 30, 2015 Callville Bay Marina notified me that they had recovered the vessel in approximately 65 feet of water and that they had placed the vessel in the parking lot on a trailer.
  
  On July 31, 2015 Game Warden and I went to Callville Bay Marina.  I photographed the vessel and talked with employees from Callville Bay Marina.  They stated that they were still unsure why the vessel sank.  They stated that they were going to place the vessel on stilts and fill the bilge with water to see if the vessel was leaking.  They had received a video of the accident from a bystander, which they emailed to me.
  
  On August 1, 2015 Callville Bay Marina placed the vessel on stilts in the parking lot.  Game Warden and I photographed the hull of the vessel and observed an approximately 3.5 inch crack on the underside of the hull on the port side.  I talked with Callville Bay Marina staff who stated that they were able to get the engine started and would likely be able to salvage the engine and repair the vessel.
