The Tunnels and Water System of Chicago : Under the Lake and Under the River

Wallis describes the completion of the first great tunnels, built in response to the polluted waters of the Chicago River and Lake Michigan. Winters also produced the problem of fish finding their way into the water supply: "Every drop of water the city drank was highly flavored with fish, and one was obliged to look twice in his goblet to see that he did not swallow one alive."
