The Soldier River is a tributary of the Missouri River, located in western Iowa. It is approximately 90 miles long and flows through the counties of Crawford, Ida, and Monona. The river was named after a soldier who drowned while fording it during the Blackhawk War in 1832. The Soldier River's hydrology is fed by precipitation and snowmelt, and it is primarily used for agricultural purposes such as crop irrigation and livestock watering. The river also has two major reservoirs, the Crawford Creek Impoundment and the Soldier River Reservoir, which are used for flood control and recreational activities such as fishing, boating, and camping. Several smaller dams along the river also provide recreational opportunities for locals and visitors alike.
