Ten imperiled aquatic species (nine fishes, three of which are federally listed as endangered or threatened, and a caddisfly) are known to inhabit the Etowah basin, and five others (mussels) are believed extirpated.
The Etowah Aquatic HCP is proposed to formally cover the three federally listed fish species. The other six fish species are not proposed to be
formally covered by the HCP but will benefit from the avoidance, minimization and mitigation measures in
ways very similar to the listed species. The Etowah Aquatic HCP can serve as an appropriate basis for an HCP
for these six species should they be listed in the future.
The amber darter (Percina antesella) and the Etowah darter (Etheostoma etowahae) are federally listed as endangered, while the Cherokee darter (Etheostoma scotti) is listed as threatened; both the Etowah and Cherokee darters are endemic to the Etowah. The Coosa madtom (Noturus munitus), freckled darter (Percina lenticula), holiday darter (Etheostoma brevirostrum) and bridled darter (Percina sp. cf. macrocephala) are state-listed in Georgia and likely to be considered candidates for federal listing.
