The South Fork Big Nemaha Watershed (HUC 10240007) covers approximately 247,000 acres in Kansas and Nebraska. The hydrology of the watershed is characterized by intermittent streams and shallow groundwater recharge. Snowpack is not a significant factor in the watershed. Surface water in the watershed includes streams and several small reservoirs used for irrigation and recreation. The primary reservoirs are Lovewell Reservoir and Glen Elder Reservoir. The watershed is primarily used for agriculture, with corn and soybeans being the predominant crops. Interesting climatic facts include the occurrence of severe droughts in the 1930s and 1950s, as well as a trend towards warmer temperatures in recent decades. However, the long-term climate data for the area is limited. Overall, the South Fork Big Nemaha Watershed is an important agricultural region with several small reservoirs that contribute to the local economy and recreation.
