lake michigan and chicago river



There was a time when the Chicago River did what all rivers do when confronted with a downhill run and a large body of water at the end of that run: it flowed east into Lake Michigan. Then, as the city grew with people, railroads, more people, more freight—both rail and ship—more people, manufacturing, retail, people, the river became the premier sewer of the region, moving all its waste into Lake MIchigan. Oh, my! Polluting the lake! What do we do?!?! Reverse the flow of the river, of course, to move the stuff somewhere else. Here is a concise history of the river from the Encyclopedia of Chicago. And here is a USGS map of the river system today.

Ah, what we do to clean up our messes, eh?

The Chicago Harbor Lighthouse was first built in 1893 at the mouth of the Chicago River. In 1917, after the Navy Pier was built, it was moved out here at the end of the breakwater in the harbor.

My Dad (project manager) built the latest part of Chicago's ongoing effort to clean up it's waterways.

The Leg of the Deep Tunnel that ran roughly under or near the river from Wilmette to the South Side. was built by Kenny Construction and others.

This massive holding tank was to capture combined runoff and waste sewage and hold it until it could be treated by the Metropolitan Sanitary District.
