What We Know About Upper Yakima Bull Trout Populations: Isolated populations of bull trout living in the Upper Yakima Basin face significant challenges such as blocks to adult migration, degraded instream habitats, and invasive species. Sensitive to warming temperatures, they are also increasingly challenged by a changing climate. As a result, Yakima Basin bull trout populations currently consist of low numbers of adult spawners. Extreme seasonal dewatering presents an additional challenge, resulting in frequent stranding and desiccation of juveniles.
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.
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
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.
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.
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;
Xapnish Property - Toppenish Creek
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.
