Taxonomic Comments
Buth et al. (1992) found that Chasmistes cujus and Catostomus tahoensis were diagnostically different for 20 genetic characters; they found no genetic evidence of hybridization in a sample suspected, on the basis of morphology, to be of hybrid origin.

Hybridizes with C. platyrhynchus, the mountain sucker (Lee et al. 1980). See Smith (1992) for a study of the phylogeny and biogeography of the Catostomidae.

Range Extent20,000-200,000 square km (about 8000-80,000 square miles)
Number of Occurrences21 - 80
Rank Reasons
This species is somewhat broadly distributed, considered common, and is not subject to any major threats.
Range Extent Comments
The Tahoe sucker is native to the Lahontan Basin in southeastern Oregon, Nevada, and northeastern California, USA (Page and Burr 2011). Based on specimen records from Global Biodiversity Information Facility and observations from iNaturalist, range extent is estimated to be approximately 168,000 km² (GBIF 2023, GeoCat2023, iNaturalist 2023). It has also been introduced in the upper Sacramento River system, California, but this non-native range was not considered for this range extent estimate (Page and Burr 2011).
Occurrences Comments
This species is represented by dozens of occurrences (GBIF 2023, iNaturalist 2023).
Threat Impact Comments
There are no major threats to this species.
Ecology & Habitat

Habitat

Habitat is primarily large lakes and reservoirs but also includes pools along lower reaches of streams (Lee et al. 1980, Page and Burr 2011). In Lake Tahoe, adults usually are at moderate depths (move into shallower areas at night), whereas young are found in shallow water or in tributary streams. In Pyramid Lake, these suckers occur in inshore waters in summer, offshore in winter. In lakes, spawning occurs over rock and gravel substrates, in water 5-18 meters deep. In streams, spawning occurs in gravel riffles.

Ecology

All age classes school to some extent (Sigler and Sigler 1987).

Reproduction

Spawns mainly April-early summer. Sexually mature at 4-5 years in Lake Tahoe, 2-3 years in Pyramid Lake. Lifespan 4-5 years in Pyramid Lake; grows slower and lives longer in Lake Tahoe.
