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

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.
