† Populations may not be currently present.
Means of Introduction: Apparently introduced to June Lake and to the Santa Clara River system as a result of a release of Owens River water from the Los Angeles Aqueduct (Moyle 1976; Bell 1978). Introduced into the Owens River sanctuary as a conservation precautionary measure (Moyle 1976).
Status: Established in parts of California outside its native range, including populations in June Lake and those in the Owens Valley sanctuary (Moyle 1976). The status of the introduced Santa Clara River population is uncertain (Moyle 1976; Bell 1978).
Impact of Introduction: Possible hybridization with the Santa Ana sucker Catostomus santaanae in the Santa Clara River system (Moyle 1976; Bell 1978).
