Deep Tunnels and Fried Fish: Tracing the Legacy of Human Interventions on the Chicago River

Reversing the flow of the Chicago River is just one of many interventions to the natural system. In section II, the authors trace the historical use of innovative engineering approaches for managing the Chicago River. Then, the article analyzes two current engineering solutions that continue the pattern of human intervention. Section III turns to the tunnel and underground reservoir project, the vast system of deep tunnels designed to manage wastewater and storm water flooding. Section IV reviews the aquatic nuisance species dispersal barrier or electric fence as it is commonly referred to. This barrier is a last ditch effort to protect the Great Lakes watershed from the Asian carp
