Túuši Wána Design Project Touchet River RM 14

The Confederated Tribes of the Umatilla Indian Reservation (CTUIR) proposes this design project on the mainstem Touchet River. The design will focus on a 3 mile stretch of the mainstem channel. The 3 mile stretch runs from river mile (RM) 14.2 to 17.2 in Walla Walla County. The overall outcome of this project phase is to create a final (100%) engineered stamped peer-reviewed design that will lead to an instream restoration project. Is is anticipated that the deign will set the stage for a process-based restoration project consistent with the CTUIR River Vision. As such, the design will focus on reconnecting floodplain as well as restoring fish habitat primarily by adding instream variety where it is now absent. Mid-Columbia steelhead, bull trout and re-introduced Chinook salmon all migrate through this reach and spend part of there adult and juvenile life there. This project will improve the conditions in the river for these species as well for other aquatic species of interest to the Tribes like lamprey and fresh water mussels.

The primary objective is to create a 100% design and construction documents within one year of funding that will, when implemented, enhance habitat for native fish and wildlife by facilitating more natural ecosystem function throughout the site.
