The area is characterized by forests, wetlands, and lakes, with the Chippewa River being the largest and most important waterbody. The hydrology of the region is heavily influenced by snowmelt, with spring snowpack contributing significantly to streamflow. The region experiences cold winters with an average snowfall of 60-70 inches, and mild summers. Surface water quality in the region is generally good, although some areas have been impacted by agricultural runoff and urbanization. The region also has several reservoirs, including the Holcombe Flowage and the Lake Wissota reservoir. Interesting climatic facts include the region being prone to severe thunderstorms and tornadoes in the summer months, and an increasing trend in winter precipitation over the past few decades.
