Lamar Valley to Yellowstone River Confluence is a stretch on Lamar River, Wyoming.

Also called Lower Lamar and Lamar Canyon.

It is fishable and wade only.

Montana Angler: a 7 mile stretch, less pressured; the Northeast Entrance Road bridge divides it roughly in half; upstream is a steep canyon with car-sized boulders. Firehole Ranch uses 'Lamar Canyon' and 'Lower Lamar' (river veers away from roads for its last leg).

It is downstream of Lamar Valley.
