East Fork Grays River, Mitchell Creek & Left Bank Tributary Restoration Project


The Cowlitz Indian Tribe (Tribe) has secured grant funding through the Washington Recreation and Conservation Office (RCO), from Washington Coastal Restoration and Resiliency Initiative (WCRRI), and the Salmon Recovery Funding Board (SRFB), to procure materials and implement a large-scale 3.1 mile instream habitat restoration project on the East Fork Grays River, and adjacent tributaries called Mitchell Creek and Left-bank Tributary, located in Pacific County, Washington.


General Information:

The Cowlitz Tribe previously solicited bids from contractors to supply certain materials for this project to streamline construction given the limited in-water work window. In support of this and other upcoming restoration projects, the Cowlitz Tribe purchased and harvested 40.7 acres of timber roughly adjacent to this project site. All trees were tipped over whole with rootwads attached and decked within the nearby harvest units. Average DBH of harvested timber is 13 inches. Additionally, the Tribe had approximately 200 large diameter (24-54 inch) oversized logs and whole trees with rootwads attached (ranging in 30-70 foot length) delivered to the project site for use as key logs in proposed large wood habitat structures and engineered log jams (ELJ’s). All wood proposed for this restoration project is decked onsite and is available to the selected contractor.

The legacy of an ancient people in southwest Washington is rich with descendants who manage a growing portfolio of health, education, scientific research, housing, transportation, development, elder care, conservation and legal issues. The Cowlitz Tribe is a growing force in community building in what are now Clark, Cowlitz, Lewis and parts of Pierce, Skamania and Wahkiakum Counties, a vast territory occupied by numerous Cowlitz villages prior to non-Cowlitz exploration and seizure. Today, an elected Tribal Council is composed of professionals adept at managing multiple programs and projects.
