The Lower Republican Watershed (HUC 10250017) covers an area of approximately 2,260 square miles in the states of Kansas and Nebraska. The hydrology of the watershed is primarily influenced by the Republican River, which is fed by several smaller streams and tributaries. The area is characterized by a semi-arid climate with hot summers and cold winters. The specific snowpack varies from year to year, but typically accumulates in the winter and melts in the spring, contributing to spring runoff. Surface water in the watershed is used for irrigation, municipal water supply, and recreation. The primary reservoirs in the area are Harlan County Reservoir and Milford Lake. Interesting climatic facts include occasional severe droughts and floods, which can impact the hydrology of the watershed. In recent years, there has been a trend towards drier conditions and decreased snowpack, which may have implications for water availability in the future.
