RedactedNarrative: Vessel 1 was travelling downriver; at the time, the dam upstream was releasing water and the current was moving at approximately 2000 CFS.  Vessel 1 then struck a tree, ejecting both parties on board into the water.  Both parties were able to climb on top of Vessel 1 and hold onto the tree that was struck.  Both parties were rescued by the Division of Watercraft and transported to the hospital for hypothermia.
