The winged mapleleaf is an endangered freshwater mussel found in the St. Croix River in Minnesota and Wisconsin, the Ouachita and Saline Rivers in Arkansas, and the Bourbeuse River in Missouri. The St. Croix River contains the only population known to be reproducing. Propagation efforts are progressing with hopes of restocking portions of the mapleleaf's historic range.
