The endemic Cahaba shiner (Notropis cahabae) was described in 1989 from individuals collected in a 76-mile-long section of the upper Cahaba River. It was listed as an endangered species when its known range decreased to less than 15 river miles. A new, possibly larger, population of Cahaba shiners was discovered in the main channel of the upper Locust Fork in 1998.
