Freshwater mussels have also rebounded because of the improvement in water quality. During 2000 and 2001, DNR divers sampled nearly 200 sites from Dayton south to Red Wing. They counted more than 12,000 specimens of 27 species. Thirty years ago they would have had difficulty recovering any live mussels at all from much of that stretch.

Divers found shells of two federally endangered mussels, the Higgins' eye pearly mussel and winged mapleleaf but did not find live specimens, suggesting the species had recently vanished from the stretch.
