Lake Winnebago is the largest inland freshwater lake in Wisconsin, covering an area of 137,700 acres. The lake is located near Stockbridge, Wisconsin, and has played an important role in the region's history, serving as a transportation route for Native American tribes and European explorers. The hydrology of the lake is influenced by several tributaries that provide surface flow, including the Fox River, Wolf River, and Fond du Lac River. Additionally, the lake's snowpack provides a significant amount of water during the winter months. The lake is used for recreational activities such as fishing, boating, and ice fishing. The surrounding agricultural land uses the lake as a source of irrigation and drinking water.
