RedactedNarrative: On Sunday 29 August 2021, I responded to a hit and run boat accident that took place up the Emory River portion on Watts Bar Lake. According to owner and witnesses, a black and white jet ski hit the back of their wakeboard boat.  The individual on the jet ski reboarded his jet ski and took off.  OP1 and his passengers stated they were drifting at the time trying to adjust their wake when the jet ski came up from behind turned at the last second and struck the rear of their vessel with the left side of his jet ski.  After the collision, when everyone was determined to be uninjured, Occupant asked the guy on the jet ski if he was ok the unknown individual said yes reboarded his vessel and took off.  OP1 looked over his boat saw there was considerable damage and went back to Webster Road Access Area where he called 911 then TWRA dispatch.  The accident occurred approximately 5:30PM.  This all occurred on Watts Bar Lake in Roane County.
