RedactedNarrative: Both passengers boarded the kayak to travel down the North Platte River.  As they approached a diversion dam, they both decided to go over the top of the dam rather than portage around it.  The survivor stated that the drop when going over the dam was much larger than he had anticipated and when they hit the water on the other side both were ejected from the kayak.  The survivor stated that he saw the other passenger a few times as he surfaced trying to get out of the current but was unable to get to her.  The survivor was able to grab onto rocks and pull himself out of the river.  He observed the other passenger floating face down in the river.  Survivor attempted CPR but was unable to resuscitate the other passenger..
