|In 1885, a cholera and typhoid epidemic killed thousands when sewage was washed into Lake Michigan, the source of drinking water for the city. By 1890 the Chicago Sanitary District succeeded in reversing the flow of the Chicago River to divert sewage away from Lake Michigan. The Chicago River System is more than 150 miles long and has one island.
It is a thrilling sight for tourists and residents (at least this resident) alike.
I live within a half mile of this place and walk my dog there and ride my bike there almost every day.
