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.

Where the river changes
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.
