CTUIR Fish Habitat Restoration in the Grande Ronde River Basin

The Confederated Tribes of the Umatilla Indian Reservation (CTUIR) Grande Ronde Subbasin Restoration Project was initiated by the Confederated Tribes of the Umatilla Indian Reservation in 1996 to protect, enhance, and restore riparian and instream habitat for natural production of anadromous salmonids in the Grande Ronde River Subbasin.

The project is coordinated with multiple basin partners to promote land stewardship and enhance habitat for focal fish species, primarily spring Chinook salmon, summer steelhead, bull trout, resident trout and other native species. Emphasis is placed on improving juvenile rearing habitat and adult spawning habitat by restoring natural channel morphology and floodplain function, cold water refugia, and complex aquatic habitat that supports required life histories for focal species.

Project Goal

Protect, enhance and restore functional, healthy and sustainable floodplain, channel and watershed process for the purpose of protecting and restoring fisheries and aquatic species in the Grande Ronde Basin.

Project Objective

Specific project objectives are developed to address habitat limiting factors determined during baseline surveys and assessment. Objectives for reporting period are directed towards planning/design of new projects in preparation for implementation.
