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.

3-D Habitat Enhancement Project

This fish habitat enhancement project recreates habitat that is below historical and potential conditions. A total of 7 logjams were constructed in areas that would naturally accumulate wood, channel migration rates will be slowed while improving fish habitat. Large woody debris (LWD) was partially buried in adjacent banks and it extends out into the active channel. Buried vertical snags are associated with each logjam site to provide stability and increase wood recruitment.

Nason Creek Inner Zone Project Identification

A Reach Assessment (RA) of the Lower White Pine Reach (LWP) of Nason Creek, Chelan County, WA was completed in 2009 by the USBR. The RA examines the condition of fluvial geomorphic processes and the effect on salmonid habitat, and identifies priority restoration strategies and areas. The effort presented in this document builds on the work completed in the RA by identifying more specific project opportunities within portions of the reach.

Upper Wenatchee Stream Corridor Assessment and Habitat Restoration Strategy

The Yakama Nation Upper Columbia Habitat Restoration Program has completed an assessment of site conditions and potential restoration projects in the Upper Wenatchee river.  This assessment evaluates aquatic habitat and watershed process conditions in order to identify habitat restoration strategies.  For more information, see the report and appendices attached.

Entiat Stilwaters 3-D Reach Assessment

In 2009, the Yakama Nation  procured field investigations and analyses for fish habitat project alternatives for Reach 3-D of the Entiat River.  The 3-D Reach starts at River Mile (RM)24 and ends at RM 25.  The 3-D reach has been listed as a priority reach by the Bureau of Reclamation's Priority Reach Assessment Analyses.  The Regional Technical Team (RTT) selected priority reaches and drafted priority actions for implementing habitat actions on February 11, 2009 for the Stillwate
