Yellowstone National Park

Lewis River

This river drains Shoshone and Lewis lakes and is a tributary of the Snake River. In 1872, members of the second Hayden survey called the river "Lake Fork" because it was a fork of the Snake that began in those two lakes. An 1876 map showed the river marked "Lewis Fork" (of the Snake), named from Lewis Lake.

Directions

From Grant Village Intersection: Travel approximately five miles south. You'll find the river just north of Lewis Lake on west side of the road.
