The Iron River is a 31-mile-long river in northern Wisconsin that flows into Lake Superior. It played an essential role in the history of the region, serving as a transportation route for early settlers and loggers. The river's hydrology is characterized by its relatively steep gradient, rocky bottom, and clear water. There are several reservoirs and dams along the river, including the Delta Reservoir, which was created in 1923 to generate hydroelectric power for the area. Today, the Iron River is used primarily for recreational purposes, including fishing, boating, and camping along its banks. The river also supports local agriculture, providing a vital water source for crops and livestock in the surrounding area.
