Mill City Falls is a 3' riverwide ledge across the river just before the take out for the popular Packsaddle run.  It is generally run left or right of center to avoid "Waterspout Rock"  which, as the name implies, tends to spout water and is often used as a marker.  There are rocks in the river right channel that can cause issues for inflatable kayaks and smaller craft.

Mill City Falls can be scouted from the take out during the shuttle on the pedestrian bridge.
