Yellow (Wisconsin R. trib) - CTH.N to CTH.A (Little Bull Falls) (up to 7 miles) (WI)
A short ways down (maybe 50 yards) is a road which is underwater at boatable flows which has a culvert/bridge on river right that could potentially pull a swimmer under and into a possible snag. The submerged road also forms a runnable low-head dam-type feature. (It was runnable for our group at our flow, but be sure to scout before running this and each of the dams in the park.)
