Likely under 50 cfs. Likely too low for any real whitewater.
USGS lists a sampling site (nearly a mile upstream of our 'hypothetical put-in') with drainage area of 9.3 square miles.
This location may prove at least as likely a put-in/access point, either from the road, or (with permission) parking at the St. Norberts Catholic Church to carry across a ball field which backs upon the creek.
