The Middle Wabash Busseron Watershed (HUC 05120111) covers an area of approximately 1,660 square miles and is located in west-central Indiana. The hydrology of the watershed is primarily influenced by the Wabash River and its tributaries, including the Busseron Creek. The watershed experiences a humid continental climate with hot summers and cold winters. The region typically receives 25-30 inches of snow annually, which can contribute to springtime flooding. Surface water in the watershed contains high levels of sediment and nutrients, which can lead to harmful algal blooms and other water quality issues. There are several reservoirs within the watershed, including the Sullivan Lake and Shakamak State Park Lake, which are popular for recreation. In recent years, the watershed has experienced an increase in extreme weather events, including intense rainstorms and extended periods of drought, which can have significant impacts on agriculture and water resources.
