The Ninnescah Watershed (HUC 11030016) covers an area of approximately 3,362 square miles in south-central Kansas. The watershed is characterized by a semi-arid climate, with average annual precipitation of 28 inches, and a high evapotranspiration rate due to the warm temperatures. The Ninnescah River is the main waterbody in the watershed, and it is fed by several tributaries. The watershed is home to several reservoirs, including Cheney Reservoir, which provides drinking water and recreational opportunities. The snowpack in the Ninnescah Watershed is typically low due to the semi-arid climate. Surface water is limited in the summer months, with intermittent streams and dry riverbeds being common. The reservoirs in the watershed are also impacted by sedimentation and nutrient loading, which can affect water quality. Climate trends in the Ninnescah Watershed include increasing temperatures and variable precipitation patterns. Drought events have become more frequent in the region, which can impact agriculture and water resources. Land use changes, such as urbanization and agricultural expansion, can also impact the hydrology of the watershed.
