Watershed Hydrology

The Maple Watershed (HUC 09020205) is located in the Upper Mississippi River Basin and spans over 3,000 square miles in southeastern Minnesota and northeastern Iowa. The watershed is heavily influenced by agriculture and includes a mix of croplands, grasslands, and forests. The hydrology of the watershed is characterized by multiple streams that eventually drain into the Upper Mississippi River. The Maple Watershed experiences a continental climate with cold winters and hot summers. Snowfall is common in the winter months, and the snowpack acts as an important water source for streams and rivers during the spring melt. Surface water quality in the watershed can be impacted by agricultural runoff, sedimentation, and nutrient pollution. Moreover, reservoirs in the Maple Watershed provide important water storage for agricultural irrigation and drinking water supply. Recent climate trends in the Maple Watershed include increasing temperatures, more frequent extreme precipitation events, and longer growing seasons. These changes have the potential to impact the hydrology and ecology of the watershed, including changes in streamflow, water quality, and vegetation patterns.
