Here are a couple of pictures of Dam Number 4, which is scheduled to be removed this winter.
Both of these photos were taken two days ago from the east bank of the river in Rosemont.
This is a low-head dam, which present drowning dangers for canoeists. After the water rolls over the seeming harmless dam a hydraulic boil develops, which is why low-heads are dubbed "drowning machines." The actions of the boil have prevented freezing--whereas most of the Des Plaines is presently frozen over.
