RedactedNarrative: Three occupants launched Vessel 1, a canoe.  The river current was strong and water levels were high.  They navigated downstream a short distance and ended up striking debris/trees on the right shoreline after losing control.  The collision caused the canoe to tip.  All three occupants were tossed from the canoe and began to be swept downstream.  They attempted to get to the canoe with their gear in it, but were unsuccessful.  They were able to get to the bank.  One of the occupants had a cell phone in a dry bag and called 911 for assistance.  No injuries
