RedactedNarrative: On Friday, July 15, 2022, I was contacted about a vessel that had struck one of the TVA oxygen lines at the low end of Fort Loudoun Reservoir on the previous evening.  Subject stated that he had struck the line that was at the surface and that he wasn't sure if there had been any damage to his vessel.  After he had a chance to inspect his vessel, he discovered some damage to the bottom of his vessel and it was slowly taking on water.  He contacted me on July 18, 2022 and requested an accident report.
