Engineering & Design RFP - Nason Creek Floodplain River Mile 3.4 to 4.6 Project

The Yakama Nation Fisheries is seeking proposals from qualified engineering firms to award an engineering services contract in support of salmon habitat restoration activities taking place in Nason Creek in Chelan County, Washington.  Based upon the proposals received under this solicitation the Confederated Tribes and Bands of the Yakama Nation will award a design contract to the best quality bidder for the Scope of Work described within this RFP. 

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

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.  

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.

Pacific Lamprey Project

The Yakama Nation is working to restore natural production of Pacific lamprey to a level that will provide robust species abundance, significant ecological contributions and meaningful harvest within the Yakama Nations Ceded Lands and in the Usual and Accustomed areas.

Twisp River Cattle Management

The Twisp River Cattle Management Project provides riparian protection for Upper Columbia Steelhead in the Twisp River Watershed. The project was done on federal lands in partnership with the United States Forest Service (USFS).

Chewuch River 8 Mile Ranch Project

The 8 Mile Ranch Project (8 Mile Ranch) restores habitat and hydraulic refuge for fish rearing and holding within one reach of the Chewuch River. The work performed provides fish habitat, stream complexity and restores a functional riparian zone in an area currently without any vegetation.

Branch Creek Armored Stream Crossing

Branch Creek enters North Fork Toppenish Creek at river mile 3.2, and drains a 23-square-mile watershed. Mid-Columbia River steelhead use the stream for spawning and rearing. Two locations on Branch Creek were identified as suitable for culvert removal and replacement by armored stream fords. One is located at RM 1.1 and the other at RM 1.4. The project is located in the NW1/4, NE1/4, Township 9 North, Range 14 East, Section 1, on tribal trust land in the closed area of the Yakama Reservation.
