Location: Chicago River Esplanade in the north bank of Chicago River ..
The Nicholas J. Melas Centennial Fountain was built in 1989 to commemorate the 100th anniversary of the Metropolitan Water Reclamation District of Greater Chicago. It is is located at McClurg Court and the Chicago River
The Water Arc Every hour on the hour, from 10:00 to 14:00 and again from 17:00 to midnight, the esplanade's Centennial Fountain shoots a massive arc of water across the river for 10 minutes. The entire exercise is meant to commemorate the labor-intensive reversal of the Chicago River in 1900, which tidily began sending all of the city's wastes downriver rather than into the lake.
