The Red River of the North defines the winding boundary between Minnesota and North Dakota, its deep meanders cutting through the flat agricultural lands of Polk and Grand Forks Counties. In this mid-century landscape, the natural flow of the Turtle River and Grand Marais Creek is supplemented by an extensive system of engineered waterways, including Judicial Ditch No 75 and County Ditch No 41. These features reflect the area's intensive effort to manage drainage for farming on the Red River Valley floor.
