Ecology: Inhabits slow moving spring pools and associated runs; primarily associated with aquatic vegetation (e.g., watercress) where it feeds and reproduces (Boschung and Mayden 2004; Duncan et al 2010).
Means of Introduction: The species was originally stocked to create a second population. At the time of the original introduction, the species was known only from Glenn Springs. That site was immediately adjacent to Jefferson County Route 20, and would have been imperiled by any road expansions. In 1965, 43 specimens from Glenn Springs were stocked in Prince Springs in hope that a second population would afford the species more security (U.S. Fish and Wildlife Service 1980a; Howell, personal communication). The Watercress Darter was listed as a federally endangered species in 1970 (U.S. Fish and Wildlife Service 1980a). The species was later discovered at two other sites during a survey conducted between 1977 and 1978. During the period 1976-1977, all three native populations were at risk. Glenn Springs deteriorated because of sewage contamination; Thomas' Spring was to be dredged, the sportfish removed and then replaced with catfish; and the Roebuck Springs population contracted "gas bubble" disease (U.S. Fish and Wildlife Service 1980a). On 19 January 1988, 400 fish were transplanted from Roebuck Springs, 200 to Tapawingo Springs and 200 to Avondale Springs, as part of an endangered species recovery plan designed to save this species from extinction (U.S. Fish and Wildlife Service 1992).
Status: Established at Tapawingo Springs (Howell, personal communication). Failed at Prince Springs, possibly due to competition from redfin darters E. whipplei (U.S. Fish and Wildlife Service 1992). Sampling the year after the initial transplant failed to find any individuals. Additional sampling trips in the past ~30 years also have failed to find any individuals (Howell, personal communication). The transplant is believed to also have failed at Avondale Springs (Howell, personal communication). No individuals have been recovered; however, the site is difficult to sample (U.S. Fish and Wildlife Service 1992).
Impact of Introduction: The introduction of Watercress Darters to Tapawingo Springs caused the extirpation of rush darter (E. phytophilum), a Federally Endangered species of darter described in 1999, at that locality (George et al. 2009)
