Yellowstone Trout Salmo lewisi (Girard)

The Yellowstone or Lewis trout inhabits the Snake River basin above Shoshone Falls, and the headwaters of the Missouri. It is abundant throughout this whole region in all accessible waters, and is particularly numerous in Yellowstone Lake. As already stated the trout of Yellowstone Lake certainly came into the Missouri basin by way of Two-Ocean Pass from the Upper Snake River basin. One of the present writers has caught them in the very act of going over Two-Ocean Pass from Pacific into Atlantic drainage. The trout on the two sides of the pass cannot be separated, and constitute a single species.
