RedactedNarrative: On 06/15/2015 at appox 09:36 I received an email from Region 4 dispatch regarding a  property damage boating accident that had occurred on 06/14/2015.  I called the owner/operator and made arrangements to  meet him later that evening.  At appox. 18:00 I went to his residence.  He stated that on 06/14/2015 he was loading his PWC''s on a trailer at Roddy Branch Access Area on the Little River in Blount County.  After Vessel 1 was loaded on the trailer he started loading Vessel 2 and lost control of Vessel 2 and hit Vessel 1.
