The Yellowstone cutthroat trout (Oncorhynchus clarkii bouvieri) is a subspecies of the cutthroat trout (Oncorhynchus clarkii). It is a freshwater fish in the salmon family (family Salmonidae). Native only to a few U.S. states, their original range was upstream of Shoshone Falls on the Snake River and tributaries in Wyoming, also across the Continental Divide in Yellowstone Lake and in the Yellowstone River as well as its tributaries downstream to the Tongue River in Montana.[2] The species is also found in Idaho, Utah and Nevada.[3]
It is believed that it got into Yellowstone River (which drains into Atlantic) from Snake River (which drains into Pacific) drainages through a small creek known as Parting of the Waters. It is one of the few aquatic species that has crossed a continental divide.[4][5]
