RedactedNarrative: On April 24, 202 at approximately 1120 hours, I, Game Warden 1, was notified of a vessel that had been stranded in Cresent Cove located in the Virgin Basin of the Lake Mead National Recreation Area of Clark County. The weather was rough with high winds expected over the next couple days and waves ranging from 2-4 foot in height. 
  
  The reporting party (RP) was Callville Marina who had been in contact with the stranded party the night prior. Callville Marina had rented a 59-foot houseboat to the party who brought along a personally owned 21-foot open bow boat. The renting party stated their rented houseboat had run aground and had swamped their personal boat due to the high winds the night prior. I was assisted by my Field Training Officer, Game Warden 2.
  
  The RP stated they had talked to the renting party and all occupants were safe and unharmed. The RP had asked that NDOW conduct a welfare check on the occupants and vessels. While enroute to the stranded vessel's location we made contact with a representative from Callville Marina. The representative stated they were able to the houseboat back into the water and off the ground, but the eight (8) occupants were unable to be taken aboard due to the winds. We were informed that the marina had two waiting deck boats for the occupants to get them back to the marina. The deck boats were positioned in the “narrows” of Lake Mead where the wind was navigable. We offered to take the occupants from their location to the awaiting deck boats for safety concerns. 
  
  Upon arrival I observed a red and white vessel, California identification, on the shore facing in a south-east direction. The vessel's port side was high in the air with the starboard side in the water being filled by water with each wave coming onshore. Debris from the vessel was strown in the water. Water filled the boat in its entirety due to the waves over the starboard side gunnel. East of the swamped vessel was the rented houseboat. The houseboat appeared to be removed from being stranded as we were previously informed. 
  
  Once ashore I was able to make contact with all eight (8) occupants who denied any injuries. One of the occupants, later identified as Operator, was the owner of the swamped vessel. All occupants were asked to don their personal floatation devices from the houseboat and board the NDOW patrol vessel. Once all occupants were seated, we were able to transport them through the narrows to an unnamed cove (GPS Coordinates 36.14887, -114.57224) where the marina's deck boats were waiting. All occupants were transferred to the marina's vessels without incident and were transported to the Callville Marina. We cleared this incident shortly after.
  
  On April 26, 2021 I was able to contact Operator and have him complete a statement form. Operator's statement states that the night prior they had been sitting in the houseboat when they heard banging. They emerged from the houseboat to find his personal boat being pushed ashore by the waves. He and two others boarded the vessel and attempted to reposition it. During this attempt, the boat was swamped by oncoming waves and began taking on water. Operator and the two others exited the boat, once placed on shore, and got in the houseboat. They called the marina who instructed them to remain within the houseboat and wait for help the next day. 
  
  The houseboat was later retrieved by the marina and the swamped vessel was recovered by US Tow and taken to their secure location. A brief estimate of the damage on the vessel would show that approximately $10,000 in damage had occurred due to the amount of water in the vessel and the description of the vessel provided by the tow company once it was removed. 
  
  Nothing further.
