RedactedNarrative: Operator was anchored below the Ozark lock and dam and was going to change his position.  V1 was anchored from the bow and stern.  He first pulled the bow anchor and then began pulling the stern anchor.  At that point water started coming over the stern of V1 and within seconds V1 was submerged.  Operator managed to grab a life jacket and ice chest and made it to the rock jetty below the lock wall where he was rescued and brought back to the boat ramp.
  
  V1 is still submerged and location is unknown at this point.  The flow on the river at the time of the accident was 19,000 cfs.
