RedactedNarrative: On June 4, 2018 at approx. 1230PM, a couple launched a yellow, sit-on-top style sea kayak on the Arkansas River which was running at 1150 CFS/ Once they got into the main current, the kayak flipped over after colliding with a rock causing both passengers to enter the water. 
  
  One passenger was able to swim to shore and grab onto a rock, the other disappeared. The missing passenger was found drowned 2.5 miles downriver in an irrigation canal hours later. It was reported that the drowning victim was originally improperly wearing a Type III PFD designed for water skiing, and not swift water.  The PFD was found at the top of one of the rapids along the stretch. The victim was found not wearing the PFD. Neither passenger had experience white water kayaking
