RedactedNarrative: One 16 foot Bluefin aluminum boat with 6 occupants left Bartlett Lane boat ramp at Buffalo Bill Reservoir at approximately 5:00 p.m.  Boat travelled south and west towards the South Fork Dike to fish for walleye.  At approximately 6:00 p.m., the wind picked up from the Northwest and waves started building.  The operator started working the boat back towards the Bartlett boat ramp.  After travelling approximately 300-400 yards, the boat began taking on water.   The bilge pump was activated but could not keep up with the amount of water entering the boat.  The boat quickly filled and basically sunk.  Four juvenile occupants and two adult males left the boat.  Subject was able to turn the boat over in the water and the 4 juveniles climbed/held onto the boat.  As the boat drifted, the anchor became entangled on the bottom of the lake and stopped the progress of the boat.  Subject2 decided to swim to shore to get help.  Subject2 used a small Igloo cooler for flotation.  Passers by on the road noticed the capsized boat and reported to Park County Sheriff’s Office.  A man passing by drove to the boat ramp area where his boat was stored, launched his boat and responded to the victims.  He was able to retrieve the four juveniles and tow the boat with subject clinging to it safely to shore.  Once on shore, PCSO Search and Rescue members were able to right the boat.  All victims were evaluated at the scene by medical personnel for hypothermia and released at the scene.  The boat was removed at the scene.
