Tomyhoi Lake

Tomyhoi Lake is a lake located in the Mount Baker Wilderness, in Whatcom County, Washington. It is between Tomyhoi Peak, Yellow Aster Butte, and Mount Larrabee, just south of the Canada–United States border.
Access is via Tomyhoi Lake Trail, from FR-3065, although due to avalanche debris and downed trees the last half-mile of the trail to the shores of the lake is more difficult than the rest.
The lake was formed by a landslide dam. The water quality of the lake is considered very clear.

Recreation

Hiking is a popular activity around the lake, with a trail up the lake itself, as well as Yellow Aster Butte Trail breaking off. Camping is also available at and around the lake.
The Washington [Department of Fish and Wildlife] advertises the lakes as having an overabundant amount of brook trout and strongly encourages anglers to fish as much as is legal each day.
