Very low. Desperate boaters will find some play is possible. (Gauge does NOT track flows in this reach well. Check postings on RapidsRiders.org message board.)
Put In rapid on the Vermillion River offers a short but technical entry point for paddlers, with multiple small boulder gardens and tight technical lines requiring precise maneuvering. The rapid's entrance can be rocky and somewhat blind, demanding careful scouting and a clean approach to navigate the initial drop and subsequent rocky sections.
