The Milwaukee River is a 115-mile-long tributary of Lake Michigan that flows through Wisconsin. In the late 19th and early 20th centuries, the river was heavily polluted due to industrialization, but has since been cleaned up and is now popular for recreational activities such as kayaking and fishing. The river's hydrology is managed by several man-made reservoirs and dams, including the Menomonee and Kinnickinnic Rivers, which were dammed to create power for industrial use. These reservoirs also help control flooding in the area. The river is used for agricultural irrigation and is important for the region's economy. Today, the Milwaukee River is a symbol of the city's ongoing revitalization and commitment to environmental sustainability.
