The Iowa River is a tributary of the Mississippi River and runs about 329 miles across the state of Iowa. It has been an essential part of Iowa's history, being used for transportation of goods, power generation, and irrigation. The river's hydrology has been significantly impacted by agricultural practices, with high levels of sediment and nutrient runoff leading to water quality issues. Several dams and reservoirs have been constructed along the river to control flooding and provide recreational opportunities, including the Coralville Reservoir and Dam, Lake Red Rock, and the Iowa City Reservoir. These reservoirs provide water for irrigation and recreation, including boating, fishing, and camping. The Iowa River remains an important part of Iowa's landscape and economy, with efforts being made to improve water quality and preserve its ecological health.
