The Yahara River is a tributary of the Rock River in southern Wisconsin in the United States. It is about 62 miles (100 km) long (including the distance across intervening lakes), and drains an area of 536 square miles (1,390 km2). Via the Rock River, it is part of the watershed of the Mississippi River. The Yahara River links the lakes around which the city of Madison was built.
The river rises in the town of Windsor in northern Dane County and flows for a short distance in the town of Leeds in Columbia County, then returns to Dane County and flows southward through the village of DeForest, the unincorporated community of Windsor, and the towns of Burke and Westport into Lake Mendota in the city of Madison. Downstream from Lake Mendota, the river turns southeastward and flows through Lake Monona, Lake Waubesa and Lake Kegonsa, and passes through the city of Monona, the village of McFarland, the towns of Dunn and Pleasant Springs, the city of Stoughton and the town of Dunkirk (including the unincorporated community of Dunkirk) in Dane County; and the towns of Porter (including the unincorporated community of Stebbinsville) and Fulton (including the unincorporated community of Fulton) in northern Rock County. It joins the Rock River in the town of Fulton, approximately 9 miles (14 km) northwest of Janesville.
The U.S. Board on Geographic Names (USBGN) issued a decision clarifying "Yahara River" as the stream's name in 1903. According to the Geographic Names Information System, it has also been known historically as "Catfish River", "Gahara River", and "Myan-mek." The USBGN's 1903 investigation noted that the name "Catfish River" was in widespread use in Rock County at that time, and that "Yahara River" was more commonly used in Dane County.
