1. Gathering at the Gristmill Marker
"The first settlers took land in the timber and along the streams. For one thing they doubted the value of soil on the open prairie; for another, they needed water power for their saw- and gristmills."
DuPage County: A Descriptive and Historical Guide
Between 1847 and 1887, the manmade channel below made Warrenville a booming economic and social center.
This "millrace" directed the power of the West Branch DuPage River to a waterwheel, which turned gears inside a gristmill. Area farmers brought corn, rye, wheat and other "grist" to the mill, which ground the crops into flour or meal. One prosperous mill that operated here, the Warrenville Roller Mills, ran night and day and still turned people away.
A farmer could wait in line for hours to drop off his harvest but used the time to visit and catch up on the latest news. Many even brought their children, who often swam in the millpond upstream.
