RedactedNarrative: On Friday, July 4 2014, I responded to Shoal Creek on Lake Lanier in reference to a boating incident.  Investigation revealed that the operator of vessel (1) entered Shoal Creek from a small cove on the Gwinett County side of the lake.  In doing so, he slowed his boat down to a speed that created a very large wake near a raft of four other boats.  He then turned in a manner that caused his wake to strike the side of the other boats.  The large wake, (approximately 6') caused the other boats to rock violently.  This caused anchor lines to snap and numerous items to fall from shelves and walls inside the other boats and for them to hit together.  Numerous individuals were knocked to the ground and victim (1) sustained a sprained wrist and complained of a back injury.  Vessels 2-5 were at anchor therefore had no contributing factors to the incident.
