It is about {{convert|323|mi}} long[1] and is open to small river craft to Iowa City, about {{convert|65|mi}} from its mouth. Its major tributary is the Cedar River. CourseIt rises in two branches, the West Branch and East Branch, both of which have their headwaters in Hancock County, each about {{convert|38|mi}} long and which join in Belmond.[1] The Iowa then proceeds roughly in a southeast direction, passing through the city of Iowa Falls, through a scenic valley to Steamboat Rock, then through the cities of Eldora, Marshalltown, Tama, and Marengo, and through the Amana Colonies in Iowa County. In Johnson County, it becomes impounded by the Coralville Dam in the Coralville Reservoir, which turns southward to the spillway. The river runs generally south and passes through Iowa City and the University of Iowa campus. A lowhead dam at Burlington Street in Iowa City is the last dam before the river's confluence with the Mississippi. South of Iowa City, it is joined in Washington County by the English River, and then in Louisa County it is joined by the Cedar River to flow into the Mississippi. UsesThe Iowa River is noted for recreational and commercial fishing. Game fish include largemouth and smallmouth bass, walleye, northern pike, channel and flathead catfish, crappie and other panfish. The Coralville Reservoir is commercially fished for carp and buffalo fish. Pine Lake State Park is located on the Iowa River at Eldora. FloodsThe Iowa can flood, notably in the June 2008 Midwest floods, and the Great Flood of 1993. The Cedar and its tributaries, including the Shell Rock River, can contribute to flooding events. It tore down the historical swinging bridge in Charles City, Iowa. See also
