It is unclear whether the distribution of the Independence Valley speckled dace has expanded or diminished since the sub-species was listed. Distribution trends are not known, but the species’ current range in Canada is likely similar to its modern historic range. For Speckled Dace, the current population estimate of approximately 940,000 adult fish may be low (due to sampling methodology) and its entire distribution may not have been sampled; as well, the estimate is a single one, so a population trend cannot be discerned. Throughout its broad distribution the speckled dace occurs as hundreds of divergent populations, many of which have been named as subspecies. Established in San Luis Obispo Creek and Webber Lake, California (Moyle 1976a), and in Ruby Marsh, Nevada (La Rivers 1962).
