This specimen resembled several others of around the same size and perhaps the same species, which were pretty common in my February sample from the upper Yakima. Unfortunately, I misplaced the specimen before I could get it under a microscope for a definitive ID.

The specific collection location data from this map were pulled from the Global Biodiversity Information Facility (GBIF) website under the Creative Commons license. Data there come from a variety of sources, some of which are populated by hobbyists. Both the precision of the location and accuracy of the identification could be low. This map is not an authoritative scientific source, nor an exhaustive list of everwhere this taxon is found, but it should be good enough for anglers.
