Agricultural life in this corner of northwest Minnesota is defined by an extensive drainage network, where the Clearwater River is joined by engineered waterways such as Judicial Ditch Number One and County Ditch Number Sixtyfour. This intricate system of ditches, including County Ditch Number Fiftyseven and County Ditch Number Eighteen, reflects the region's historical efforts to reclaim prairie wetlands for productive cultivation.
