The Real History Behind Reversing the Chicago River with Mr. Dick Lanyan, who spent 48 years with the Metropolitan Water Reclamation District of Greater Chicago, where he became the executive director and ran the day-to-day operations - which addresses the industrial waste load equivalent for 9 million people. Very early in our American history, the potential for Chicago to be the center of an expansive water system, connecting the East and the West with its location on Lake Michigan and along the Chicago River, prompted the federal government to establish Fort Dearborn in 1803 where Chicago now sits. There is no shortage of written and digital stories about the Chicago River and how it was reversed almost 124 years ago on January 1, 1900. It is referred to as an engineering marvel – and certainly – it took engineering know-how and back breaking work to create this “Big Ditch.”  But, the story of Chicago’s challenges as a booming metropolis started way before the re-direction of the Chicago River and has everything to do with its location on the southwestern shore of Lake Michigan and the great Chicago population boom.  Further, Chicago's days of flooding are far from over related to climate change and its continued large population.
