We will, if deemed prudent and determinable, propose to designate critical habitat for two Colorado fishes (headwater chub and roundtail chub) under the Endangered Species Act. These species are found in headwater reaches, creeks, and small rivers in Arizona and New Mexico. We are developing a listing determination as a separate rulemaking action (RIN 1018-BA86).
