The lower mainstem Yakima River is inhospitable for salmonids during much of the summer due to high temperatures. In cooperation with private landowners, This project would promote riparian recovery through public outreach, project development and implementation. Native cottonwoods would ultimately be replanted on insufficiently vegetated stream banks. Monitoring plant survival would occur for three years, replanting as necessary. Summer temperatures would be reduced, which would help rebuild existing stocks. Summer chinook, which are now extinct in the basin, could then be reintroduced.

Project development phase Implementation
Biological results achieved
Annual reports and technical papers
Specific measureable objectives
Change in riparian canopy closure will also be measured.
Restoring riparian habitat will increase rearing productivity and improve water quality.
Underlying assumptions or critical constraints
Changes in riparian canopy will be determined with a densiometer.
Brief schedule of activities
The project would begin with the mailing of fliers to landowners. Public meetings would be held to discuss stream functions, appropriate management and the goals of the project. Past habitat restoration/protection successes that the Yakama Indian Nation has undertaken would be displayed. Landowners would be solicited to voluntarily initiate riparian restoration/protection on their land. After restoration projects have been implemented in year one, monitoring would occur in years two and three. Ultimately, field trips would be scheduled to display individual restoration projects.
From past research fish managers know that summer maximum temperatures in the lower Yakima River are too high to support salmonids. This effectively truncates the out migration of zero-age spring chinook, and prevents the reintroduction of stocks that require this reach during the critical season. This project would redress rearing habitat function through increasing riparian canopy closure, reducing sedimentation, increasing in-channel habitat complexity and improving water reducing substrate embeddedness.
The lower 100 miles of the mainstem Yakima River cannot support anadromous fish because of lethal temperatures.
Summary of expected outcome
Native riparian vegetation density will increase. In turn, water quality will improve because canopy closure will improve. Ultimately, summer maximum temperatures will decrease. Ultimately the project will be used as a local demonstration area to encourage additional landowners to protect and restore streams.
Dependencies/opportunities for cooperation
The restoration project will be developed in consultation with the USDA - NRCS and the WDOE. A cost-share application will be presented to the USDA - CFSA, the WDNR, the USFWS, and other agencies that administer funding programs.
Invasive weedy species may out-competent replanted species.
Monitoring of revegetation and weed invasion be done for three years.
