RedactedNarrative: On October 8, 2014, at approximately 16:45 hours, I (Game Warden) was notified via dispatch that there was a watercraft accident on Alcova Reservoir in Fremont Canyon. WE responded to Alcova Reservoir. Upon arrival we met two individuals on shore next to a mostly submerged vessel. When asked who was operating subject admitted to being the one who was operating at the time of the collision. The other individual was the owner of the boat. Operator explained that it was his first time operating a boat ever in his life. He over corrected going around a corner in the canyon and ran over a submerged rock, thus causing damage to the underside of the boat. The boat began taking on water and they docked next to the shore and call 911. When asked how much he had to drink, Operator responded that he had one shot 5 hours earlier and that was it. I asked Operator a few questions, ran preliminary BUI maneuvers as well as Horizontal Gaze Nystagmus (HGN). Operator passed the alphabet and counting test, but failed the finger to thumb test. Operator showed no signed of HGN. Operator was not under the influence at the time of the collision. Occupant was informed that he needed to retrieve what was left of his boat as soon as he could. Operator and Occupant were taken back to Oakie Beach to their vehicle. No one was injured. Operator was issued a citation for careless operation of watercraft (W.S. 41-13-203).
