RedactedNarrative: On 06/09/19, I Game Warden was on patrol on the Colorado River, below Davis Dam. At approximately 1455 hours, I was flagged down by a Personal Watercraft (PWC) (V1) with two occupants saying that they were in a vessel collision and wanted to file a report. 
  
  Operator1 stated that he was travelling down river behind another PWC (V2) when V2 made a sharp port side turn around and began travelling upriver. Operator1 said he tried to avoid the collision but was travelling at a speed that did not allow him time to avoid the collision. 
  
  When speaking with Operator2, he stated he was travelling down river when he turned around on V2 and that when he finished his port side turn around his PWC was impacted by V1. This collision was caused by V1 operating at a high rate of speed and operating too closely to another vessel by V1 and having an improper lookout by V2.
