Adult salmon returning to the Hatchery are an important component of tribal fisheries activities. The focus of the fishery is the large pool located below the Leavenworth NFH spillway.

The fishery is important to tribal members as one of the few remaining places in Washington State that offers a productive fishing opportunity utilizing traditional methods.
