Blanchard Dam is a dam across theMississippi River, inBellevue Township andSwan River Township,Morrison County, near the city ofRoyalton, Minnesota.^[1] Blanchard is ahydroelectric station owned and operated by Minnesota Power. The dam sits slightly upriver from the formerSoo 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 accuratewater 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 theUnited States Geological Survey website.

Blanchard Dam is also one of very few known places on earth whereStaurolite is found.^[2] Here, the mineral Staurolite sometimes forms cross rocks or “fairy stones”. Blanchard Dam also has Camping and Fishing sites located within 200 yards of the dam. The Soo Line recreational trail crosses the river on a bridge located about 75 yards from the dam. The bridge is suspended about 100 ft above the Mississippi River. The original bridge remains and not been rebuilt since its use by the Soo Line Railroad.
