The Lower Big Blue Watershed, located in southeastern Nebraska, has a land area of approximately 1,270 square miles. Its hydrology is influenced by the Big Blue River, which runs through the center of the watershed, and numerous other tributaries. The area experiences a moderate continental climate, with hot summers and cold winters. Snowpack varies seasonally and is not typically a significant source of surface water. Surface water is primarily sourced from precipitation events and is used for irrigation, recreation, and municipal water supply. Reservoirs in the watershed are used for flood control and recreation. The watershed is known for its agricultural production, with corn and soybeans being the primary crops grown. Climate trends in the area include increasing temperatures and changes in precipitation patterns, which may have implications for water availability and agricultural production in the future.
