Minneapolis in Hennepin County, Minnesota — The American Midwest (Upper Plains)
Beneath the Surface
—Saint Anthony Falls Heritage Trail —
Drawing from a 1996 archaeological report of the north wall of the waterpower canal at the Pettit Mill. Water flowed through penstock openings to drive turbines in the mills.
Most of the flour companies had demolished their mills along the river by 1950, and gravel covered their foundations during the building of the Upper Lock in the 1960s. Still, many remnants of the milling era remained when this photograph was taken. The Minneapolis Eastern Railway, whose trestle looms in the foreground, once carried box cars to the mills. The Washburn A Mill appears in the foreground. It was the last mill here to operate on direct-drive waterpower.
In 1885 engineer William de la Barre (in the bowler hat) persuaded mill owners to build more efficient water power systems. Workers lengthened the canal, increased the drop to the turbines, and rebuilt railroad trestles. Visible in the photo are the Crown Roller Mill (under the arrow), the Stone Arch Bridge, and a trestle support.
De la Barre supervised work on new tailraces in about 1890. The area shown here is located just below the current entrance to the parking lot at the Upper Lock.
