The West Nodaway Watershed (HUC 10240009) covers approximately 133 square miles in northwest Missouri. It is primarily agricultural land, with corn and soybean being the main crops grown. The watershed is drained by several streams, including the West Nodaway River, which flows into the Nodaway River. The area experiences a humid continental climate, with hot summers and cold winters. Snowfall is common in the winter months, with an average snowpack of around 10 inches. Surface water quality is generally good, with some localized impairments due to agricultural runoff. There are several small reservoirs within the watershed, used primarily for recreational purposes. Interesting climatic facts include the area's susceptibility to severe thunderstorms, and the occasional occurrence of tornadoes. Trends in the watershed show an increase in precipitation in recent years, which has led to an increase in flooding events.
