The Little Arkansas watershed (HUC 11030012) covers approximately 1,550 square miles in central Kansas, USA. The hydrology of the watershed is characterized by a mix of perennial and intermittent streams, and it is primarily fed by precipitation. The watershed is also known for its specific snowpack, which can be significant during the winter months. Surface water in the watershed is largely used for agricultural irrigation purposes. The main reservoirs in the area include Cheney Reservoir and El Dorado Reservoir, which serve as important sources of drinking water for surrounding communities. Interesting climatic facts include the occurrence of frequent thunderstorms during the summer months and the occasional occurrence of severe weather events such as tornadoes. There has been a trend towards increased precipitation in the watershed in recent years, leading to concerns over flooding and erosion.
