The Watonwan River is usually calm, but can flow quickly at times. Many paddlers enjoy the 30-mile segment from Madelia to the river's confluence with the Blue Earth River at Garden City. You'll pass sloping, tree-lined banks with farmland just beyond. There are no major rapids. Be alert for the occasional snag (fallen tree), which may tip an unwary paddler.
Established in 1996 as a state water trail, the Watonwan River's name has changed slightly from its original name, Watanwan, which means "where fish bait abounds" in Dakota.

This route is for experienced paddlers. Enjoy beautiful scenery as you paddle an area of challenging Class I rapids, view nearby Triple Falls, and pass the "Big Moe" boulder. This stretch should be avoided if river levels are high. The paved Red Jacket Trail connects both access points, offering an opportunity for a pedal (biking)/paddle experience.
