The Lower Little Missouri watershed (HUC 10110205) covers an area of approximately 6,358 square miles in western North Dakota. The hydrology of the area is dominated by the Little Missouri River and its tributaries, which provide important water resources for irrigation, recreation, and wildlife habitat. The area experiences a continental climate, with cold winters and hot summers. Snowpack is an important source of water in the winter months, and is closely monitored to predict spring runoff. Surface water in the area is highly variable, with frequent flash floods and droughts. The region also has several reservoirs, including Lake Sakakawea, which is used for hydroelectric power generation, recreation, and flood control. Interesting climatic trends include an increase in average temperatures and a decrease in total annual precipitation over the past several decades, which has implications for water resources and agriculture in the region.
