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.

Historical River Levels
The Upper Iowa River is a 156-mile-long (251 km) tributary of the Mississippi River in the upper Midwest of the United States.
Its headwaters are in southeastern Minnesota, in Mower County (Le Roy and Lodi townships) near the border with Iowa. It then flows through the Iowa counties of Howard, Winneshiek, and Allamakee, and finally into the Upper Mississippi River. Along its course, it passes through the Iowa cities of Chester, Lime Springs, Florenceville, Kendallville, Bluffton, and Decorah. Its watershed comprises nearly 641,000 acres (2,590 km2).
The Upper Iowa and its tributaries are part of the Driftless Area of Iowa, a region that was ice-free during the last ice age. Unlike areas to the south and west, the area was not planed down by glaciation or covered in glacial drift, with the result that there are steep, high-walled canyons that little resembles what one normally sees in Iowa rivers in the western and southern regions of the state. The lack of any serious development makes this the only river in Iowa eligible for designation as a National Wild and Scenic River. It has not yet attained this status, partly because much of the land and the riverbottom itself are privately owned.
It is an excellent river for canoeing, taking paddlers through the scenic bluff country. Many put their canoes in at Kendallville or down river from there, but some more intrepid paddlers prefer to start at Lime Springs by the Lidtke Mill or at Florenceville.
A number of wildlife refuges and preserves dot the river's basin. Bird sightings on the river usually include bald eagles, great blue herons, turkey vultures, and barn swallows.
In April 2007, the Iowa Natural Heritage Foundation announced the purchase of 1,224 acres (5 km2) of additional land; currently off limits to the public, stabilization and restoration work will be done to the riverbank, with removal of non-native vegetation and replanting with more appropriate species.
The Upper Iowa was sometimes historically called the "Iowa River", creating confusion with the larger Iowa River to the south. The Upper Iowa was also called the "Oneota River", and the large number of Late Prehistoric sites along its bluffs caused the early archaeologist Charles R. Keyes to name the Oneota Culture for the river.
