On arrival I identified the victim as Operator2, and Operator1 as the cause of the accident.  Operator1 stated that he and Operator2 were operating the PWCs in the canyon section of Glendo Reservoir.  He stated they were making their way back towards the main body of water in Elkhorn Bay when he started carving turns.  He turned his PWC and a large wage splashed him and obscured his vision.  At this point he saw Operator2 in front of him, but was unable to stop the machine before colliding into Operator2’s left leg.  I then interviewed Operator2.  Operator2 stated they were leaving the canyon and making their way into Elkhorn Bay when Operator1 began making turns.  Operator2 slowed down and veered to the right to go around Operator1.  At the same time, Operator1 had also slowed down, turned and collided with Operator2, striking him in his left leg.  Neither individual reported consuming alcohol, SFSTs and PBT results of 0% blood alcohol content confirmed this.
 
On July 12 2013, I (Game Warden) was conducting watercraft safety inspections on Glendo Reservoir. At approximately 13:08 hours while patrolling the area of the dam, I was contacted by SALECS of a boat accident involving two PWCs and that the individuals are currently located at Whiskey boat ramp. 
 
At 13:10 hours I arrived at Whiskey boat ramp. Wyoming State Park Rangers were already on scene as well as an EMT that happened to be in the area. The victim was lying on the dock having first aid applied to his leg by the EMT; I identified him as the victim and made sure the area was safe and if any medical aid was needed from me; none was. Operator2’s leg appeared swollen with a few cuts/scratches around his knee; there was no sign of bleeding. 
 
I then identified the operator of the PWC that collided with Operator2. Operator1 states that he and Operator2 are acquaintances and that Operator2 rents the basement of his home. 
At this time, an ambulance from Platte County arrived to tend to Operator2, and I began my interview with Operator1. 
 
Operator1 stated that he and Operator2 were operating the PWCs in the canyon section of Glendo Reservoir. He stated they were making their way back towards the main body of water in Elkhorn Bay when at he started carving turns. He turned his PWC and a large wake splashed him and obscured his vision. At this point he saw Operator2 in front of him, but was unable to stop the machine before colliding into Operator2’s left leg. He states that both individuals were able to stay on and maintain control of their PWC and were able to safely operate the machines back to Whiskey boat ramp.

Operator1 had pulled both the PWCs off the water and onto his trailer where I inspected and took pictures of both machines for documentation. I was unable to see any sign of related damage to either of the PWCs. 
At approximately 13:17 hours I checked to see if Operator2 was still in good condition and contacted Laramie Regional Supervisor to inform him that an accident had occurred, he was in the area and arrived on scene shortly after. 
 
While Warden interviewed Operator1, I stepped into the ambulance to interview Operator2. Operator2 stated they were leaving the canyon and making their way into Elkhorn bay when Operator1 began making turns. Operator2 slowed down and veered to the right to go around Operator1. At the same time Operator1 had also slowed down, turned and collided with Operator2, striking him in his left leg.
 
I then asked Operator2 if he had consumed any alcoholic beverages that day, to which he responded that he hadn’t had a drink in a long time. I then asked if he was under any prescription drugs, to which he responded yes, propanol for high blood pressure
