RedactedNarrative: On sunday, october 11, 2015, two people set out to powerboat on the nolichucky river in hamblen county, tennessee. Operator and passenger launched a 2009 17'' alumacraft from a private ramp located off state route 160. Operator and passenger departed the private ramp around 15:00 hours and began recreational cruising. Operator navigated downstream, and came upon a head dam known to the indigenous population as enka dam. As the dam rapidly approached, operator realized his craft and all persons on board were in imminent peril. His failure to maintain a proper lookout and careless operation ultimately led to an avoidable collision with enka dam.
