Response Statement - Umatilla Dace
This small freshwater fish has a limited distribution in Canada encompassing habitats that have been extensively modified by widespread hydroelectric developments (change from riverine to reservoir habitats, altered flow regimes). It is likely that habitat will continue to be lost and degraded owing to hydroelectric operations, climate change, and increased water extraction. This species is also susceptible to aquatic invasive species that are widespread in the Columbia-Kootenay Rivers’ portion of the species’ range.  Proposed additional hydroelectric and water storage development in the Similkameen River drainage is a potential major threat to habitat quality.
