PROTECTION STATUS: Not listed
RANGE: Utah's west desert, Wasatch Front, and the Sevier River
THREATS: Urbanization, water development and groundwater pumping, livestock grazing, and competition from nonnative species
POPULATION TREND: The decline of the least chub was first noted in the 1940s. By 1996, local extirpations in many areas where this fish was once abundant set it on the path to the brink of extinction, with only six remaining wild populations intact.
