Middle Lewis River Falls is a massive 33-foot vertical waterfall that requires precise boat positioning and expert-level skills to navigate safely. Paddlers must execute a near-perfect centerline drop with minimal margin for error, avoiding dangerous undercut rock formations and potential pin hazards on either side of the narrow vertical descent. Extreme caution is required, with mandatory scouting and safety support recommended due to the high consequence nature of this technical Class V waterfall.
