The Redwood River originates near Ruthton, among the wind farms high atop the Buffalo Ridge. The elevation at its source, makes the Redwood one of the flashiest rivers in the state. The most canoeable portion of the river begins near Marshall and ends at Lake Redwood in Redwood Falls. Those who wish to continue on the Redwood to the Minnesota River will have to portage around the Lake Redwood Dam under the Highway #19 Bridge, re-entering in Alexander Ramsey Park.
