RedactedNarrative: Two PWCs carrying 3 passengers each were operating near the North Shore of John Martin Reservoir. Operator 1 of Vessel 1 was making sharp turns trying to spray Vessel 2, which caused Vessel 1 to capsize. All passengers were wearing Type 3 PDFs fitted correctly. Two passengers resurfaced, but Victim 1 was trapped under the capsized Vessel 1. Operator 2 of Vessel 2 drove over to Vessel 1 and rescued Victim 1 from the water. Victim 1 was unresponsive for 30 seconds before Operator 2 performed CPR after which Victim 1 coughed up water and became responsive. Operator 2 brought Victim 1 to shore where they vomited but remained conscious. An ambulance transported Victim 1 to a hospital to receive further medical attention.
