Question

Why did builders and engineers change the water flow of the Chicago River? Please Answer And I Will Reward!

Answer 1

Finally, in 1900, the Sanitary District of Chicago, then headed by William Boldenweck, completely reversed the flow of the Main Stem and South Branch of the river using a series of canal locks, increasing the river's flow from Lake Michigan and causing it to empty into the newly completed Chicago Sanitary and Ship Canal. In 1999, this system was named a 'Civil Engineering Monument of the Millennium' by the American Society of Civil Engineers (ASCE).[5] Before this time, the Chicago River was known by many local residents of Chicago as "the stinking river" because of the massive amounts of sewage and pollution which poured into the river from Chicago's booming industrial economy. Through the 1980s, the river was quite dirty and often filled with garbage; however, during the 1990s, it underwent extensive cleaning as part of an effort at beautification by Chicago Mayor Richard M. Daley.
