DistributionRead full entry
Global Range: (1000-5000 square km (about 400-2000 square miles)) According to most recent literature, the range includes the Goose Lake basin, Oregon and California, where the subspecies is widely distributed in Goose Lake (average elevation 1,433 meters) and occurs also primarily in low-elevation sections of tributary streams (to 1,441 meters in California and at least 1,550 meters in Oregon), including, in California, Lassen, Willow, Branch, and Corral creeks (Moyle et al. 1989), and Dry Creek, Drews Creek and tributaries, Antelope Creek, Thomas Creek, Cox Creek, and the north and south irrigation canals in Oregon (Heck et al. 2008). Genetic data indicate that the tui chubs in the upper Pit River drainage below Goose Lake also should be included in the taxon thalassinus (Chen et al. 2009). With the Goose Lake and Pit River populations, Harris (2001) included tui chub populations in the Cow Head basin and Warner basin in thalassinus, which he regarded as a distinct species (S. thalassinus). Pending peer-reviewed publication of Harris's (2001) dissertation, we here regard the range of thalassinus as encompassing the Goose Lake basin and (following Chen et al. 2009) the upper Pit River basin. but not the Cow Head or Warner basins. Goose Lake is a disjunct subbasin of the upper Pit River and as recently as 1868 and 1881 occasionally overflowed into the upper Pit River (Chen et al. 2009).
