Blanchard Dam is a dam across the Mississippi River, in Bellevue Township and Swan River Township, Morrison County, near the city of Royalton, Minnesota.[1] Blanchard is a hydroelectric station owned and operated by Minnesota Power. The dam sits slightly upriver from the former Soo Line rail bridge. The bridge now carries a recreational trail.

Blanchard Dam is the tallest dam on the Mississippi River at 47 feet of water head.[citation needed]

Because of its design, it provides the most accurate water flow statistics of the Mississippi in central Minnesota. Daily, monthly and yearly statistical data in cf/s (cubic feet per second) since 1924 are available at the United States Geological Survey website.

Blanchard Dam is also one of a very few known places on earth where Staurolite is found.[citation needed]
