The owner/operator launched his boat from the Utah Marina and was traveling to an East Shore Sub-division when a storm arose.  He was unable to make the sub-division north of Idaho's East Beach Campground and pulled the boat just below the campground.  He unloaded his passengers by which time the vessel was taking on water.  It swamped and as the waves continually crashed against the vessel it sunk a short time later.  The vessel was left in the lake over night as this storm occurred in the late afternoon/evening around 18:30.
