RedactedNarrative: Operator was paddling his inflatable paddleboard when he somehow fell off into the water. He was seen splashing in the water by a witness. She said he yelled and it appeared that he was trying to get the attention of a boater nearby. She ran along the bike path to the south side of the lake to get closer and saw him go under the water and not resurface. His body was found about 3 hours later. He was not wearing a life jacket. The paddleboard was not required to be registered. Alcohol was not a factor.  Operator's drug use (THC) was listed as a factor.
