Buffalo-Whitewater
Watershed Hydrology
The Buffalo Whitewater Watershed (HUC 07040003) covers an area of approximately 1,650 square miles in southeastern Minnesota. The watershed is characterized by rolling hills and agricultural land use. The hydrology of the watershed is dominated by the Whitewater River and its tributaries, which provide the majority of surface water flow. The area experiences a continental climate with cold winters and warm summers. The watershed receives an average of 30-35 inches of precipitation per year, with snowfall being a significant contributor to the winter months. The watershed contains several reservoirs, including the Lake Pepin Reservoir, which is used for recreational activities and as a water supply source. The water quality in the watershed is generally considered to be good, although there are concerns about nutrient enrichment and sedimentation. In recent years, the area has experienced an increase in extreme precipitation events, which can lead to flooding and erosion.
