Round Lake anchors this southern Minnesota landscape where the high plateau of the Coteau des Prairies shapes the drainage of the region. This 2019 survey captures the highly engineered water system of Nobles and Jackson counties, where an intricate network of agricultural infrastructure like Judicial Ditch Number Nine, Judicial Ditch Number Thirteen, and County Ditch Number Ten regulates the flow across the prairie. These man-made channels connect natural water bodies such as Plum Lake and Illinois Lake, eventually feeding into the W Fork Little Sioux River.
