The Pomme de Terre watershed (HUC 10290107) covers an area of approximately 1,106 square miles in southwestern Missouri. The hydrology of this watershed is dominated by small streams and tributaries that flow into the Pomme de Terre River. The area receives an average of 45 inches of precipitation annually and experiences a humid continental climate. Snowfall is relatively light and typically melts quickly due to the mild winter temperatures. Surface water in the watershed is used for recreation, drinking water, and irrigation. Pomme de Terre Lake, a reservoir in the watershed, is managed for flood control and provides recreational opportunities. The primary constituents of the reservoir include sediments from erosion and nutrients from agricultural runoff. Trends in the watershed include increased urbanization and agricultural intensification, which can impact water quality and quantity.
