The Yahara River (/jəˈhærə/) is a tributary of the Rock River in southern Wisconsin. 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.
