The site navigation utilizes arrow, enter, escape, and space bar key commands. Left and right arrows move across top level links and expand / close menus in sub levels. Up and Down arrows will open main level menus and toggle through sub tier links. Enter and space open menus and escape closes them as well. Tab will move on to the next part of the site rather than go through menu items.
Here's a mostly bird's-eye view of the project from start to finish
Construction projects tend to generate a significant amount of interest from the public — especially grown men — and that definitely was the case with the Hammel Woods dam removal and modification project in Shorewood.
From people stopping on Jefferson Street and blowing past barricades to watch or pleading with us on social media to provide more updates than we did, it seemed everyone wanted to get a glimpse of the action. That action moved quickly.
The removal project, funded by the Lower DuPage River Watershed Coalition, began in July with an estimated completion date of October, but it wrapped up a month early. We were there every step of the way to document the process.
Here’s a look back.

The first step was to install a cofferdam to stop the flow of the river around the worksite. (Photo by Chad Merda)
The cofferdam had metal frames for support. (Photo by Chad Merda)
The dam removal was done in two stages, with crews first working on the east side of the river. (Photo by Chad Merda)
Tarps were placed over the metal frames and secured on the riverbed with sandbags. The water inside the cofferdam was then pumped out. (Photo by Chad Merda)
The dam was then exposed and crews had a safe and dry working environment. (Photo by Chad Merda)
It was then time to get an excavator in there to get to work. (Photo by Chad Merda)

The rocks help create riffles in the water, which will oxygenate it. (Photo by Chad Merda)
Once attention turned to the west side of the river, the work included removing the concrete overlook connected to the dam. (Photo by Chad Merda)

As part of the project, an ADA-accessible kayak launch was installed south of where the dam had been located. (Photo by Chad Merda)
