This is an example of a rolling dam that I could not photograph in Yorkville, IL because they had already replaced theirs with a safer design. I took the following picture to grab the big splash by the dam above the picnic table.
When I zoomed in even further, you could see the foundations of mill ruins.

I took some ground level pictures of the water flowing through the ruins. This one was the best.
