Yellowstone River

The Water: The Yellowstone River is the longest undammed river in the lower 48 and is always changing. It is float-only with 671 fishable miles to explore. The Yellowstone River hosts 61 fish species with 41 native fish species including: Sturgeon, Catfish, Paddlefish, Yellowstone Cutthroat Trout, Mountain Whitefish, and non-native Brown and Rainbow Trout.

Namesake: The two most common beliefs are that the Yellowstone is named from the Minnetaree name meaning Yellow Rock River, or named from the Cheyenne for the sandstone bluffs on the lower Yellowstone.

Headwaters: The North Fork and South Fork flow from peaks in the Absaroka Range at the Continental Divide flowing North and feed Yellowstone Lake in Yellowstone National Park.

Estuary: The Yellowstone River is the principal tributary of the Missouri River, flowing into the Mighty Mo just across the Montana/North Dakota border outside of Williston, N.D.
