The Missouri River defines the western edge of this landscape, carving through the boundary between Sioux and Emmons Counties. This 2024 survey documents the expansive waters of Lake Oahe, where the river’s original course has widened into significant features like Cattail Bay. To the north, Winona Island and the adjacent Winona Flats mark a shift in the riverine environment, where the floodplains meet the higher North Dakota prairie.
