LEVEL OF CONCERN: MODERATE
Mountain whitefish persist in some fragmented water bodies in California, but their overall abundance and distribution are reduced from historical levels and may be continuing to decline. Population estimates and comprehensive distribution surveys are lacking; while their overall status remains uncertain, it appears to have declined.
Based on current limited research, Mountain whitefish populations appear to have become constrained by poor water quantity and quality throughout their range. Ongoing water diversion and drought have combined to reduce suitable available habitat for the species.
