About the upper iowa river


The Upper Iowa River is a 156-mile-long tributary of the Mississippi River that flows through the northeast region of Iowa. The river originates in the highlands of Minnesota and flows through a series of rapids, pools, and limestone bluffs before entering the Mississippi. The river has a significant history, with early settlers using it for transportation and powering mills. Today, the river is mainly used for recreational purposes such as fishing, canoeing, and camping. There are several dams and reservoirs along the river, including the Lake Hendricks Dam and the Upper Iowa Dam, which provide hydroelectric power and serve as popular recreational areas. The agricultural industry also benefits from the river, with local farmers using the river for irrigation and livestock watering.
