RedactedNarrative: On 07/18/18 at 5:57 pm, operators were Operating their personal watercraft's (PWC) approximately 200 yards east of the east boat ramp located at Spring Shores Marina on the Lucky Peak Reservoir.
     Operator1 and Operator2 were operating within close proximity of each other, jumping their PWC's off each other's wake. At one point, Operator1 lost control of his white 1994 Kawasaki PWC and was thrown into the water. While Operator2 was jumping Operator1's wake, his purple 1996 Kawasaki PWC approached Operator1 who was in the water. Operator2 did not see Operator1 in the water and as his PWC passed Operator1, the port side of the stern of his PWC collided with Operator1's head. This impact with Operator1 caused an approximate one 1 inch laceration to the back of Operator1's head. Operator1 was also knocked unconscious.
     Witnesses approached Operator1 and removed him from the water. At that time, Operator1 regained consciousness. Operator1 was transported by boat to the east ramp of the Spring Shores Marina where I made contact with him. I asked Operator1 if he knew what happened. Operator1 stated he couldn't remember anything after he launched his PWC into the water and didn't remember the collision or being knocked unconscious. I asked Operator1 if he consumed any alcoholic beverages today. He said no. I did not observe any indicators of impairment. I then made contact with Operator2. Operator2 also denied consuming any alcohol and I did not observe any indicators.
     Operator1 was evaluated by Ada County Paramedics. Operator1 was treated on site for his injuries and declined to be transported to the hospital. 
     I photographed both PWC's and provided the report information to Operator1 and Operator2.
