Flow is moderated by dams upstream of run thus increasing the window of runnability slightly.
Visual from CR553 bridge (near Marquette Mountain Ski Area, at listed take-out for upper section, put-in for lower section) or visual inspection of rapids below dam at put-in.
We also look at the outflow of the pipe through which water is diverted around the dam at the put-in.
At a "full pipe" this run will be a real hands-full. Boaters should proceed with caution at 'full pipe' levels, as there are many twists and turns, and the river is prone to having deadfall and snags (since it seldom gets a chance to 'flush'). Boaters must be ready to catch 'one-boat-eddies'. With a "half-pipe" the run is much more forgiving.
(Note: "Full pipe" will not really quite fill the end of the pipe due to the upturned angle.)
Best month to catch it is April, May (about half as likely), October and November (about half that likely).
