Watonwan River
Template:Use American English Script error: No such module "Infobox".Template:Template otherScript error: No such module "Check for unknown parameters". The Watonwan River is a tributary of the Blue Earth River, Script error: No such module "convert". long, in southern Minnesota in the United States. Via the Blue Earth and Minnesota rivers, it is part of the watershed of the Mississippi River, draining an area of Script error: No such module "convert". in an agricultural region. The Watonwan drains about a quarter of the Blue Earth River's watershed.[1]
The river was the site of the capture of Bob, Cole and Jim Younger (members of the James–Younger Gang) near Madelia in 1876.[2]
Geography
The Watonwan River rises in Amboy Township, approximately Script error: No such module "convert". southwest of Jeffers in central Cottonwood County, and flows generally eastwardly across flat till plains through northern Watonwan and western Blue Earth counties, past the city of Madelia. It flows into the Blue Earth River approximately Script error: No such module "convert". southwest of Mankato and Script error: No such module "convert". upstream of the Blue Earth's confluence with the Minnesota River.[1][3][4]
The river's largest tributaries are its north and south forks. The South Fork Watonwan River,[5] Script error: No such module "convert". long, rises in southeastern Cottonwood County and initially flows eastwardly into southern Watonwan County, briefly entering Martin County and passing Odin; then northeastwardly through eastern Watonwan County to its confluence with the Watonwan River upstream of Madelia. The North Fork Watonwan River,[6] Script error: No such module "convert". long, rises in Cottonwood County and flows eastwardly into northern Watonwan County, joining the Watonwan River about a mile (2 km) southeast of La Salle.[7][3]
Approximately 84% of the larger watershed of the Blue Earth River, which includes that of the Watonwan River, is used for agricultural cultivation, primarily that of corn and soybeans.[1] Small lakes and wetlands in the Watonwan watershed provide significant habitat for Minnesota's waterfowl population, though many stretches of the river and its tributaries have been subject to ditching and channelization for agricultural production and localized flood reduction.[2]
Flow rate
At the United States Geological Survey's stream gauge near the community of Garden City in Garden City Township, Script error: No such module "convert". upstream from the river's mouth, the annual mean flow of the river between 1940 and 2005 was Script error: No such module "convert".. The highest recorded flow during the period was Script error: No such module "convert". on June 20, 1993. The lowest recorded flow, caused by an ice dam, was Script error: No such module "convert". on December 24, 1989.[8]
