Montello Lake is formed from the Montello River which flows into the Fox River at what we now know as the City of Montello in Marquette County, Wisconsin. If you work your way back to the source of the Montello River, you’ll find it called Westfield Creek as well as the Crooked River. The little river is a hard worker, dammed in Westfield and generating power there for the Westfield Power Company and dammed also at Harrisville where it also generated power until recently. The Montello dam today, generates power for North American Hydro.
