In crisis
The species is endangered and is protected in areas such as the Watercress Darter National Wildlife Refuge in Jefferson County. The IUCN lists it as being "Endangered" due to its small range, small total population size and vulnerability to deterioration in the quality of the water in the springs in that it occurs. The FWS has ordered the dam to be restored and the pond refilled in an effort to save the remaining darters.
The Alabama Department of Conservation and Natural Resources is suing the City of Birmingham for destroying endangered species and their wetland habitat.
