The Lower Minnesota Watershed (HUC 07020012) spans over 8,500 square miles in Minnesota, and encompasses parts of Blue Earth, Brown, Le Sueur, Nicollet, Redwood, Renville, Sibley, and Watonwan counties. The watershed is characterized by its rolling hills, fertile soils, and abundant natural resources. Hydrologically, the Lower Minnesota Watershed is fed by numerous small tributaries and streams, which flow into the Minnesota River. Snowpack is an important component of the watershed's hydrology, as it contributes to spring runoff and groundwater recharge. Surface water quality in the watershed is generally good, with some impairments due to agricultural and urban runoff. The watershed features several large reservoirs, including the Lac Qui Parle and Upper and Lower Redwood Reservoirs. Interesting climatic facts include the watershed's relatively high precipitation rates, which average around 30 inches per year. Recent trends in the watershed include increasing urbanization and agricultural intensification, which may have impacts on water quality and quantity in the future.
