The Lower North Loup Watershed (HUC 10210007) covers an area of approximately 1,030 square miles in central Nebraska. The watershed is primarily agricultural, with corn and soybean being the dominant crops. The North Loup River is the main waterway in the watershed, and it is fed by several smaller creeks and tributaries. The area experiences a humid continental climate with cold winters and hot summers. The snowpack varies from year to year depending on the amount of precipitation received. The watershed contains several reservoirs, including Calamus Reservoir and Davis Creek Reservoir. These reservoirs are used for recreation, irrigation, and flood control. The surface water quality in the watershed is generally good, but there are concerns about sedimentation and nutrient runoff from agricultural activities. Climate trends indicate that the area is experiencing more frequent and intense precipitation events, which can lead to flooding and erosion.
