The Lower Saline Watershed (HUC 08040204) covers an area of approximately 1,925 square miles in central Kansas. The area is characterized by a continental climate with hot summers and cold winters. The watershed is largely agricultural, with crops such as wheat, corn, and soybeans dominating land use. The hydrology of the watershed is influenced by the Smoky Hill River, Saline River, and their tributaries. The region experiences moderate annual precipitation, with the majority of rainfall occurring in spring and summer. Snowpack is generally low, and snowmelt contributes to the surface water supply. The two major reservoirs in the watershed, Kanopolis and McPherson, serve as important sources of drinking water and recreation for the region. Interesting climatic trends include increasing temperatures and precipitation variability in recent years. Drought conditions have also been observed in the area.
