The Wisconsin River is a major tributary of the Mississippi River, stretching over 430 miles from its source in northern Wisconsin to its confluence with the Mississippi River. The river has a rich history, once serving as a major transportation route for fur traders and loggers. Today, the river plays an important role in Wisconsin's economy, supporting hydroelectric power, agriculture, and recreation. The river is home to several large reservoirs, including Lake Wisconsin, Petenwell Lake, and Castle Rock Lake, which are used for power generation and flood control. The river is also a popular destination for fishing, boating, and camping. Agricultural uses of the river include irrigation for crops and livestock watering. The hydrology of the Wisconsin River is closely monitored to ensure sustainable use and protection of this valuable resource.
