Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
The Notropis calientis faces severe threats from habitat degradation and water extraction in its limited desert spring systems. Agricultural development and groundwater pumping have dramatically reduced water levels in the thermal springs this species depends upon. Introduced predatory fish species and habitat modification from recreational activities further compound the pressures on remaining populations.
Habitat
This species is endemic to thermal springs and associated outflow streams in desert regions of the southwestern United States. It requires warm, clear spring waters with specific temperature ranges and minimal flow variation.
