Kinnickinnic (Milwaukee trib)

Zooming in, one can see a somewhat significant cement 'jump' between Bennett Avenue & Stack Drive. This could (at some flows) cause a significant stopper (hole), or . . . perhaps (at other, perhaps at most or all) flows, water may just 'sheet' quickly downstream from its base.

Looking upstream one sees a few minor (just more than 'curb block' height) obstructions. With anything but lowest flows, these are likely to be nearly completely immersed and cause virtually no surface feature nor disturbance
