RedactedNarrative: O1 was driving v1 back towards the boat ramp after fishing. V1 was headed west, into the waves. A large wave hit v1 and came over the bow. O1 believes that v1 then lost power and v1 was turned sideways. Another large wave than flipped v1 upside down. None of the occupants were able to retrieve life jackets before the boat was overturned. P2 used a cell phone to call 911. 911 would not connect, so he called brookings police department. The brookings police department, transferred the call to huron police department. Wco responded to the call and located v1. All occupants were rescued. V1 was towed to shore and removed from the lake on 06/16/2014. Alcohol or drugs were not factors in the accident. The wind/waves were the cause of the accident.
