Fishing in Yellowstone's Northeast

Overview of Yellowstone, highlighting northeast region

Includes the Yellowstone and Lamar rivers and tributaries between the north park boundary and Chittenden Bridge near Canyon.

  • Blacktail Pond area is closed to public use and travel, including angling, until July 1 to protect nesting birds and sensitive vegetation.
  • Only a State of Montana fishing license is required to fish the Yellowstone River, downstream of Gardiner, Montana.

Permanently Closed to Fishing

  • Trout Lake inlet stream is permanently closed to fishing to protect spawning cutthroat trout.
  • Yellowstone River, from Chittenden Bridge near Canyon downstream through the Grand Canyon of the Yellowstone to a point directly below Silver Cord Cascade, is permanently closed to fishing to ensure angler safety.

Possession Limits

Native Trout Conservation Area

  • Catch and release all native fish.
  • No possession limit on nonnative fish.

To preserve native cutthroat trout in the Lamar River drainage— including Slough Creek and Soda Butte Creek—all nonnative fish, including rainbow trout, brook trout, and identifiable cutthroat/rainbow hybrids must be killed in these areas:

  • Lamar River drainage, including all tributaries and lakes, upstream from the Lamar River Bridge.
  • Slough Creek drainage, including all tributaries and lakes, upstream from the campground.

In areas downstream of these locations, killing of nonnative fish is recommended, but not required. If you don’t know, let it go.
