RedactedNarrative: On May 10, 2020, Game Wardens were attempting to rescue a group of stranded boaters off the shore, just west of Swallow Bay at Lake Mead.  An emergency call came over the radio from National Park Service Dispatch about a capsized vessel with 12 people in the water just east of where we were working.  I broke off and quickly arrived on the scene of the capsized vessel.  There were 12 people all over in the water.  I immediately began pulling people out of the water and requested more officers to join me.  I pulled 4 females and one male out of the water at which time Game Warden was on scene. We learned that there was a 3 year old female trapped under the capsized vessel that was still floating upside down.
  
  There was an adult male with the vessel, the grandfather of the missing child, who began helping me hook a tow line to the bow eye so the vessel could be towed to shore in an attempt to make rescue efforts easier.  As I began towing into shore, the vessel began sinking rapidly and dragging the rear of my boat down.  The male that I had pulled out of the water was standing at the tow rope with a knife and I had him cut the tow line.  Grandfather was still with the vessel and Warden moved in and hooked a tow line to the bow with the help of Grandfather and towed the vessel into a protected shoreline.  I immediately took off all of my duty gear and, along with multiple members of the party, began rescue efforts for the trapped juvenile.  Warden went back out and finished retrieving individuals off a reef.  As more Game Wardens and National Park Service Rangers arrived, we were able to pick the bow of the vessel up far enough for Game Warden to get under, locate the juvenile, and pull her to safety.  She was immediately transferred to National Park Service medics and was determined to be unharmed.
  
  Based on the operator and witness statements, as the vessel was heading out into the lake to return to the marina, the waves were so bad, that the operator decided to go back to shore.  As he turned, they struck a submerged reef, which put about a 2-foot-long by 3-4-inch-wide gouge in the underside of the hull towards the bow.  As this happened, large waves broke over the stern of the vessel and swamped it.  As the vessel began to sink, the operator ordered everyone out of the boat.  All were able to get off the boat except for the 3-year-old juvenile.  Statements said that there were 11 people on board the vessel, however, when trying to officially document and identify those 11, only 10 could be officially documented as having been on board.  All but 1 person in the water had PFDs on, the male that I pulled out of the water did not have on a PFD but was able to use a Type IV style PFD to stay afloat.  The grandfather, who was in the water was Grandfather, who had swam out from shore.  He did not have on a PFD either.
