The Amana Millrace begins 6.5 miles west of here at the Iowa River. Workers from the seven Amana villages first began construction in 1865 using hand tools and oxen-drawn scrapers and wagons. The earthen levees were reinforced with wood posts and fascines, bundles of sticks and branches bound tightly together. Progress on the canal was slow until the community purchased a steam powered dredge to complete the project. Water first flowed through the turbines in Amana in 1869, and maintaining the millrace proved as challenging as its construction. Siltation in the canal was a constant problem. In the 19th and early 20th centuries dredge boats were used to keep the channel flowing. Each year the dredge boat and its crew worked their way upstream from here, and the four-man crew lived on the boat. The kitchen houses in the village closest to where the dredge was working provided meals for the crew. Colony folklore held that the canal is deepest near Middle Amana because the dredge boat crew was fond of Middle Amana cooking and lingered there. Dredging the canal required each bridge over the millrace to be dismantled and reassembled as the dredge passed. In winter the dredge was moored just upstream from this location. In the 1920s the dredge boats were replaced with gasoline powered draglines that traveled along the levees.
