Minnehaha Creek is a tributary of the Mississippi River that extends from Lake Minnetonka in the west and flows east for 22 miles. The creek might have been unremarkable except for the 53 foot Minnehaha Falls located near the creek's confluence with the Mississippi. Minnehaha Park is listed on the National Register of Historic Places as the Minnehaha Historic District. Minnehaha Park is also within the Mississippi National River and Recreation Area, a unit of the National Park Service.
