The Yahara River is a 65-mile long tributary of the Rock River in southern Wisconsin. The name “Yahara” is a Native American word meaning “sparkling waters”. The river is an important source of water supply for the city of Madison and provides a habitat for many fish and wildlife species. The Yahara River has several reservoirs and dams. The most well-known of these is Lake Mendota, which is the largest of the four lakes that the Yahara River flows through. Other reservoirs include Lake Monona, Lake Waubesa, and Lake Kegonsa. These reservoirs provide recreational opportunities for the local community, including fishing, boating, and swimming. The Yahara River also has agricultural uses, as it passes through many farms in the region. However, the river has experienced water quality issues due to agricultural runoff and urbanization.
