Cutthroat trout, Oncorhynchus clarkii, are widely distributed along the western coast of North America. They can be found as far north as Alaska’s Prince William Sound and as far south as California’s Eel River (Willers, 1991). Their range also extends inland where they can be found on most waterways with linkages to their western range along the Pacific coast (Trotter, 1987).
