Almost certainly too low. Likely under 100 cfs.
Most likley too low for whitewater.
Access may be possible here (to shorten the trip), but shoulders are not as wide as our listed take-out. At this point you have run the best of the gradient, but there are good rips downstream of this point.
Not far downstream (run mile 3.37), School Creek encounters the Kewaunee River. Flow will be increased accordingly, and the remaining distance to the listed take-out should pass quickly.
