The Yellowstone cutthroat trout (Oncorhynchus clarkii bouvieri) is a subspecies of 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]

Population threats

Their range has been reduced by overfishing and

whirling disease in major spawning tributaries.[6]

From Birds and nature, 1904

Although lake trout were established in Shoshone and Lewis lakes in the Snake River drainage from U.S. government stocking operations in 1890, they were never officially introduced into the Yellowstone River drainage and their presence there is probably the result of accidental or illegal introductions.[6][7]
