THE YELLOWSTONE STORY

A free-flowing river from Yellowstone Lake to the Missouri

The Yellowstone leaves its namesake lake and canyon, crosses Montana’s Paradise Valley and prairie badlands, and joins the Missouri near the North Dakota line. With no large storage dam on its mainstem, snowmelt, ice and sediment still shape an unusually long connected river, even as diversion structures influence fish movement and irrigation.

For thousands of years
A river across Tribal homelands
Crow, Northern Cheyenne, Assiniboine, Sioux and other Indigenous nations have longstanding cultural and subsistence relationships with the Yellowstone basin.
1872
Headwaters included in Yellowstone National Park
Creation of Yellowstone National Park protected the lake, falls, canyon and upper river within the new park boundary.
Late 19th century
Railroad and towns follow the valley
The Northern Pacific corridor encouraged settlement and commerce along the lower valley, layering new infrastructure onto older Indigenous routes.
20th century
Diversions support irrigation
Low-head diversion structures moved water to farms but also created barriers for fish including endangered pallid sturgeon.
Modern fish-passage work
A bypass channel at Intake
A new bypass channel around Intake Diversion Dam was built to reconnect lower Yellowstone habitat for pallid sturgeon and other native fish.

FISHING

Fishing the river

Yellowstone cutthroat trout are central to the upper river in and near the national park; Montana reaches also support rainbow and brown trout, warmwater species and, far downstream, paddlefish. Park rules, Montana fishing districts, invasive-species requirements and seasonal closures differ substantially.

Before you fish
  • Rules, seasons, closures and consumption advice vary by jurisdiction and can change; consult the linked fish and wildlife agency before a trip.
  • A gauge reading describes conditions at that monitoring location; it does not establish fishing quality or safety elsewhere on the river.
