RedactedNarrative: On July 25th 2014, Lake Mead Interagency Dispatch received a 911 call about a Jet Ski accident that occurred outside of Callville Bay (CVB).  Rescue 4, Ranger and I responded to the accident. I interviewed the operator of Jet Ski #1 who stated that he stopped to see where his brother was (operator of ski #2) when he saw him coming at him. He tried to turn away and then he ran into the side of Jet Ski #1. The operator of Jet Ski #2 fell into the water and started to convulse and was not alert. He was pulled out of the water by a Good Samaritan. The juvenile operator of jet ski #2 was subsequently transported to the hospital by Rescue 4.
