The Lower Sheyenne Watershed (HUC 09020204) covers an area of approximately 2,086 square miles in eastern North Dakota. It is characterized by low-relief topography, rolling hills, and a few steep valleys. The watershed has a humid continental climate with cold winters and warm summers. The Sheyenne River, which runs through the watershed, is the primary source of surface water. The river is fed by tributaries such as the Maple River, Goose River, and the Rush River. The watershed experiences an annual snowpack, which contributes to the river flow during spring melting. The main reservoirs in the watershed are the Baldhill Dam and the Lake Ashtabula reservoir. The main constituents of the reservoirs are sediment, nutrients, and dissolved organic carbon. In recent years, the watershed has experienced an increase in extreme weather events, including floods and droughts. These events have brought attention to the importance of sustainable management of the watershed.
