Adams Street Bridge (MINIMAL CLEARANCE!)

Immediately after passing a railroad bridge you come to Adams Street Bridge. At best boatable flows, this bridge will have little (or no) clearance. (Photo is at 100 cfs on USGS gauge.)

At flows over 150-200 cfs, make certain to scout this from the take-out before putting on so you'll be aware of conditions here and have your strategy planned. Eddies exist above the bridge (on either side) but current is strong and it will take agressive paddling to be sure to catch them if you need to.

(My only run of this predated the gauge on Waubonsie, so a gauge on Mill Creek was the best reference at the time. With that gauge showing 320 cfs, there was NOT sufficient clearance to comfortably pass under this bridge. Mill Creek has 27.6 sq.mi. at its gauge, whereas Waubonsee has only 19.1 at its gauge, so (assuming a direct correlation, which may or may not be valid) that might correspond to a reading of ~220 cfs on the Waubonsie gauge. The only way to get through might have been to flip under, maybe count to ten, then roll up, but we weren't comfortable trying that.)

The take-out and confluence with the Fox River is just about 120 yards downstream, so (if you need to exit to get around Adams Street) you can decide whether to bother getting in your boat, or just keep your boat on your shoulder to walk to your vehicle(s).
