WISCONSIN FLOW REPORT
Last Updated: December 24, 2025
Wisconsin's rivers are experiencing varied streamflow conditions, with several notable fluctuations that are of interest to river and water enthusiasts. The Fox River at Oshkosh, with a significant 48.85% above normal streamflow of 6980 cubic feet per second (cfs), could indicate potential flooding, affecting local communities and possibly impacting popular whitewater areas. Conversely, the Manitowoc River at Manitowoc is running low at 77.19% below normal, with a flow of 133 cfs, which may affect recreational activities. Seasonal trends show some rivers, such as the Trempealeau River at Dodge, with an elevated flow at 61.26% above normal, possibly due to melting snow or rainfall, while others like the Bois Brule River at Brule, despite a 53.78 cfs increase in the last 24 hours, remain at a low 19.18% of their normal flow.
Specifically, the Wisconsin River at Wisconsin Rapids records a flow of 2280 cfs, 38.95% below normal, which could signal flow drought conditions, whereas the Grant River at Burton is notably higher at 28.98% above its usual flow. The St. Croix River near Danbury saw a considerable rise of 112.9 cfs in the last 24 hours, now at 12.4% above normal, which should alert paddlers and anglers to changing conditions. The state's watersheds are thus presenting a complex picture, with some areas experiencing potential flooding, such as the Fox River at Oshkosh, while others like the Manitowoc River hint at lower water levels, affecting river navigation and habitat conditions. These trends underscore the importance of monitoring streamflow data for safety and the health of Wisconsin's aquatic ecosystems.
Wisconsin is characterized by a humid continental climate with distinct seasonal variations in temperature and precipitation. Major rivers include the Mississippi, St. Croix, Wisconsin, and Menominee, which are fed by tributaries that drain into the Great Lakes or the Mississippi River. The region also contains numerous reservoirs and dams, including the Wisconsin River system and the Chippewa River. Hydrology in Wisconsin is affected by snowpack, which can lead to spring flooding, and by changes in land use and agricultural practices. In recent years, the state has experienced an increase in extreme precipitation events, leading to more frequent flooding and erosion. Overall, the state's hydrology is complex and influenced by multiple factors, including climate, topography, and human activity.
