Almost certainly too low. Likely under 100 cfs.
Most likley too low for whitewater.
The creek rounds a bend (almost 90-degrees left) just before encountering Main Street (CTH.A). It tumbles down a small ledge combination, then immediately turns 90-degrees right, passing through a vertical-walled dells as it passes under the bridge. This zig-zag/ledge-combination may cause beginner/novice boaters a bit of trouble. At high water, this is a tricky maneuver to negotiate.
This is not really a 'waterfall', not really a serious 'hazard', and is not really a 'playspot', but it is definitely one of the highlights of this run, and (if you are in doubt) should be scouted before putting-in above this location on this run. Those who are uneasy about being able to make this move might be able to portage (carrying over the highway, though it's not real easy to re-enter river downstream).
