Standing at upper Wacker Drive and Columbus, it’s always astonishing to remember that before 1803, you would be wading in Lake Michigan. The modifications that have been made to the Chicago River have included dredging, channeling, damming, tunneling, legal decisions and breaching it at its South Branch headwaters to flow away from Lake Michigan. Likewise, we have altered the shoreline of Lake Michigan and struggled with it as it fluctuated about six feet from a record low in 2013 to a record high in 2022.
