The Yahara River is fed by several creeks and tributaries, including the Badfish Creek and the Upper Sugar River. There are several dams along the river, including the Tenney Park Dam in Madison. The flow of the river varies seasonally, with the highest flows occurring in the spring during snowmelt and spring rains. During the summer months, the flow can be very low due to decreased rainfall. Interestingly, the Yahara River is home to a diverse array of fish species, including northern pike, walleye, and smallmouth bass. The Yahara River has been the subject of ongoing ecological restoration efforts, which aim to improve water quality and restore fish and wildlife habitat.
