The Loup Watershed (HUC 10210009) covers an area of about 4,300 square miles in central Nebraska. The watershed is characterized by a flat topography and is drained by the Loup River, which originates in the Sandhills region. The hydrology of the watershed is mainly driven by precipitation, and the snowpack can accumulate up to 20 inches in some areas during the winter months. The surface water in the watershed is primarily used for irrigation, domestic, and industrial purposes. The reservoirs in the watershed are mainly used for flood control and irrigation. Interesting climatic facts include the high variability of precipitation and temperature throughout the year, with summer temperatures reaching up to 100°F and winter temperatures dropping below 0°F. Trends show an increasing frequency and intensity of extreme weather events, such as floods and droughts, in the Loup Watershed.
