Restoring, enhancing, improving watershed or stream function and process.

Mel Sampson Coho Facility

Background: During the pre-treaty era, 44,000 to 150,000 coho returned to the Yakima Subbasin annually. By the mid-1980s they were extinct. Habitat loss and overharvest are factors that led to the extinction. The fish’s cultural significance combined with U.S. v. Oregon objectives to restore salmon to upriver areas resulted in the release of hatchery fish (raised outside the subbasin) beginning in the mid-1980s. 

Yakima Basin "Wood Fiesta"

The Yakima Basin "Wood Fiesta" Helicopter Aquatic Restoration project is a multi-watershed collaborative effort aimed at enhancing aquatic habitat in remote watersheds that have been greatly altered by past management practices.  Large wood will be placed in stream and on the floodplain of seven Yakima River tributaries using a helicopter to improve habitat for native fish species.  The projects are located in remote areas where terrain and or vegetation limits the use of ground-based equipment to place large wood.  More information on these projects and associated temporar

Yakama Nation Superfund Section Technical Consultant RFQ

The Yakama Nation requests qualifications (RFQ) from engineering and consulting firms to accomplish the work elements outlined in this Request for Qualifications (RFQ) and provide technical assistance to support YNF’s work on cleaning up and restoring hazardous waste sites in the Columbia River Basin. Yakama Nation will review the response to this RFQ to establish one or more technical support contracts. This RFQ will be considered viable for contracting purposes for FY2018, 2019, and 2020.

The RFQ can be found below in the Project Downloads.

Natapoc Habitat Enhancement Project (Large Woody Material Option)

 This project entails placing large woody material (LWM) along the mainstem Upper Wenatchee River in crib-like structures.  The length of the treatment will be for approximately 100 yds. however; the treatment will be non-continuous in favor of utilizing gaps in the riparian canopy as well as further minimizing disturbance to riparian bank vegetation for exact structure placement.  

Nason Creek Recreation and Large Wood Assessment

This report presents the findings of the Nason Creek Recreation Assessment.  The goal of this study is to support the work of the Yakama Nation and partners as they continue to seek ways to balance the ecological benefits of habitat restoration projects for salmonid species with the safety and recreation experience of river users.
This study employed a mix of qualitative and quantitative methods to achieve the following objectives:
- Characterize existing boating recreation use levels;

Chewuch River Reach Assessment

The Chewuch River supports populations of salmonids that are currently listed under the Endangered Species Act (ESA), including spring Chinook salmon, summer steelhead, and bull trout. Habitat for these species has been impacted by anthropogenic activities throughout the basin. Specific goals of this assessment include:
• Identify actions that address critical aquatic habitat impairments limiting the productivity of local salmonid populations.

Goodfellow/Chotzen Floodplain Reconnection

The proposed Goodfellow/Chotzen Floodplain Reconnection Project (Sunnyslope side channel) utilizes natural processes to restore floodplain functions in an approximately 5-acre area located along the left bank (north side) of the Wenatchee River at RM 1.4. The project will remove a low earthen berm from the floodplain, allowing water from an existing side channel to access a larger portion of its historic floodplain during high flows.

Sunnyslope ELJ

This project created a logjam habitat feature to stabilize approximately 800 feet of eroding left bank on the Lower Wenatchee River. THe large wood was placed above top of bank and will likely interact with the river once the bank erodes.  This project will restore large wood to this portion of the Wenatchee river channel. The large wood will provide complexity and improve fish habitat in addition to stabilizing the eroding bank.
