The Middle Sheyenne Watershed (HUC 09020203) is located in North Dakota and covers a land area of approximately 1,221 square miles. The watershed is characterized by a continental climate with cold winters and warm summers. The hydrology of the area is primarily influenced by the Sheyenne River, which is the main source of surface water. The watershed also has several reservoirs, including Baldhill Dam and Lake Ashtabula, which store water for various purposes, including flood control and irrigation. Snowpack in the Middle Sheyenne Watershed can vary significantly from year to year, with some years experiencing above-average snow accumulation and others experiencing below-average accumulation. This can have significant impacts on the local hydrology, as snowmelt can contribute to surface water flows and groundwater recharge. Interesting climatic facts and trends in the area include a long-term trend of increasing temperatures and decreasing precipitation, which could have significant impacts on the watershed's hydrology and ecosystems. The Middle Sheyenne Watershed is also home to several unique plant and animal species adapted to the region's semi-arid climate.
