“The Yahara River is a tributary of the Rock River, about 62 miles (100 km) long[1] (including the distance across intervening lakes), in southern Wisconsin in the United States. Via the Rock River, it is part of the watershed of the Mississippi River. The Yahara links the lakes around which the city of Madison was built.

The river rises in northern Dane County and initially flows southwardly past DeForest and Windsor into Lake Mendota in Madison, below which it turns southeastward and flows through Lake MononaLake Waubesa and Lake Kegonsa and passes the communities of MononaMcFarland and Stoughton. It joins the Rock River in northern Rock County, 9 miles (14 km) north of Janesville.

The U.S. Board on Geographic Names settled on “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.”

During World War II, a U.S. Navy gasoline tanker, the USS Yahara (AOG-37), was named after the river.”  – Reference source:
