RedactedNarrative: Vessel 1 was fishing when a thunderstorm blew over Willard Bay Reservoir.  The vessels anchor line wasn't long enough to keep the vessel in place so the operator decided to move the vessel toward the middle of the lake.  The vessel hit a swell causing the motor to cut out.  The operator was unable to get the vessel started again.  The wind pushed the boat into the rocky dike on the west end of the reservoir.  The anchor was placed on the rocks but the force of the wind swamped the boat to the point only the bow was visible on the water.
