The river receives contributions from several tributaries, including Token Creek and Six Mile Creek, and is impounded by several dams, including the Lake Mendota Dam. Seasonal trends in flow are typically higher in the spring due to snowmelt and precipitation, while flows are lower in the summer and fall. The hydrology of the Yahara River is influenced by human activities, including urban development and agricultural practices. A quirky fact about the Yahara River is that it is known for its excellent fishing opportunities, particularly for musky and walleye.
