Federally Threatened and Endangered Fish Species
Way to Go!
There are two federally endangered and two federally threatened species in the park. The two endangered species are the smoky madtom and the spotfin chub (turquoise shiner).
The two threatened species are the yellowfin madtom and the duskytail darter. Flame chubs are listed as a “species of concern” because they are rare within the park, but thriving in other areas within the U.S. They are all about the size of an average adult human finger.
