The Pomme de Terre River is the northern-most tributary of the Minnesota River. It is named for the potato-like native plant used as food by the Dakota inhabiting the area. Pomme de terre is French for potato. The river runs through a variety of land types, including low blufflands, woods, pasture and some farmland. Watch for farm fences that may be strung across the river! The gradient of the Pomme de Terre River is 4.1 feet per mile on average. There are no major rapids.
