The Lower Fox Watershed (HUC 07120007) covers approximately 6,350 square miles and includes portions of Wisconsin and Michigan. The Fox River is the main hydrological feature in the watershed, with Lake Winnebago being the largest surface water body. The area experiences a temperate climate with an average annual snowfall of 45 inches. The snowpack can occasionally cause flooding, especially during the spring melt. The watershed contains several reservoirs, including the Menominee, Peshtigo, and Long Lake Reservoirs, which are used for recreation, fishing, and hydroelectric power generation. The reservoirs contain high levels of phosphorous and nitrogen, which contribute to harmful algae blooms. An interesting climatic trend is the increase in extreme precipitation events in the area, which can further exacerbate flooding. Additionally, land use changes, such as urbanization and agriculture, have impacted the watershed's water quality and quantity.
