RedactedNarrative: On 07/26/2017, I was notified of a boating incident at Smith Mountain Lake involving a PWC in the area of marker R28.  Additional information indicated that a male subject, who was the operator of the PWC, had been transported by EMS to Roanoke Memorial Hospital for treatment of a possible broken leg.  Information was gathered from the operator of the PWC and a friend who was riding with him on a separate PWC.  The injured male subject advised that he hit a group of irregularly moving wake while on his PWC, causing him to be thrown from his PWC in injuring his left leg.  He denied striking any objects while operating his PWC and inspection of the PWC did not reveal any obvious damage from a collision.  The male subject that was riding a separate PWC advised that he did not see the incident but found the injured male subject in the water approximately 50' from his PWC complaining of severe left leg pain.  He then towed the injured male subject to the nearest dock and awaited EMS arrival.  The injured male subject was transported to Moneta Rescue Squad, Medic 8-3 to Roanoke Memorial Hospital for treatment.
