The Cannon River is a 112-mile-long tributary of the Mississippi River in southeastern Minnesota. The river was named after Colonel William Cannon, an early settler in the area. It starts in Rice County and flows eastward through Faribault, Northfield, and Cannon Falls before emptying into the Mississippi River near Red Wing. The river is known for its scenic beauty and has several popular recreational activities like kayaking, fishing, and camping. It also provides water for irrigation and agricultural use. The river has four main reservoirs - Shields Lake, Lake Byllesby, Lake Pepin, and Lake Tetonka - and several dams used for hydroelectric power generation. In the past, the river was used for transportation of goods, but today it serves primarily as a source of water for the local community.
