Description    


The West Fork Evans Creek Large Woody Debris (LWD) Project will improve spawning and rearing habitat along approximately 11 miles of the West Fork Evans and Sand Creeks in Jackson County through a partnership between Olympic Resource Management, Silver Butte Timber Company, Lone Rock Resources, BLM, Seven Basins Watershed Council, and the Applegate Partnership & Watershed Council. West Fork Evans Creek is designated as a “core area” and the highest priority for restoration under the Final Recovery Plan for SONCC Coho salmon. In addition to ESA-listed Coho salmon, the project will benefit fall Chinook salmon, summer and winter steelhead, and cutthroat trout. Current BLM and ODFW surveys have indicated a decline in the coho population of West Fork Evans Creek. Past management practices in the watershed have reduced the amount of LWD instream, habitat complexity, and pool habitat; modified instream habitat; and increased sedimentation.

This project will install 152 instream LWD structures and 18 blockades to exclude OHV use from 3.6 miles of unauthorized roads that provide OHV-access to the creek and adjacent riparian area. These actions will increase the quality and quantity of over-summer and over-winter rearing habitat for juveniles, improve migration and spawning habitat for adults, increase macroinvertebrate populations, improve habitat and stream channel complexity, increase the accrual and retention of spawning gravels, improve riparian health, and reduce sedimentation. These factors will increase spawning success and juvenile survival rates thereby supporting fish populations.

This proposal will support fish population recovery for ESA-listed and state-listed species and address DEQ-listed limiting factors. Partners include Olympic Resource Management, Silver Butte Timber Company, Lone Rock Resources, BLM, Seven Basins WC, ODFW, Rogue Basin Partnership, and Middle Rogue Steelheaders.


PCSRF FFY 2017 funds will be used on project costs incurred during the PCSRF FFY 2017 contract award period. State funds will be used to complete the project.Because the projects scheduled end date is after the PCSRF FFY 2017 award closes, no funds allocated for this project are reported as match to PCSRF funds.

Project Benefit    


This project will address the greatest limiting factor in the recovery of the Upper Rogue population of coho salmon as identified by the 2014 Final Recovery Plan, in West Fork Evans Creek, the area listed as highest priority for restoration. Additionally, this project will directly benefit Chinook salmon, summer and winter steelhead, and cutthroat trout. The installation of large wood and restrictions in OHV-use will increase the quality and quantity of over-summer and over-winter rearing habitat for juveniles, improve migration and spawning habitat for adults, increase macroinvertebrate populations, improve habitat and stream channel complexity, increase the accrual and retention of spawning gravels, improve riparian health, and reduce sedimentation. These factors will increase spawning success and juvenile survival rates thereby supporting fish populations.

The project will support coho salmon population recovery. It will improve the most limiting factor: a lack of quality rearing habitat. This project will increase the quantity and quality over-winter habitat by increasing complexity and over summer habitat by increasing the amount of large woody debris instream. The quantity and quality of summer habitat will be improved through increasing channel and habitat complexity. This project will increase the number and abundance of large woody debris, increase gravel retention, and reduce sedimentation of existing gravel. Juvenile coho salmon, the most limited life stage, will benefit from increased pool habitat and cover for rearing which will improve juvenile fish survival. West Fork Evans Creek contains higher densities of juvenile coho salmon than other watersheds of the Upper Rogue Population therefore relatively higher current use will increase the benefits to this population.

This project will benefit SONCC fall Chinook salmon which are present within the project area. The project area has a low gradient, however the frequency and extent of current use depends on accessibly which is tied to the timing of fall rains and streamflows. However, due to recent dam removals on Evans Creek, the extent of Chinook salmon use has been documented further upstream in the tributaries of Evans Creek than previously noted. The extent and current use of West Fork Evans Creek has not been fully studied, however adults will benefit from increased quantity and quality of spawning habitat, reduced sedimentation of existing gravel, increased sorting and retention of gravel, and increased frequency of resting pools during upstream migration.

Klamath Mountain Provence summer and winter steelhead and cutthroat trout will benefit from improved the quantity and quality of spawning and rearing habitat through the installation of large woody debris. The quantity and quality of summer habitat will be improved through increasing channel and habitat complexity. This project will increase the number and abundance of large wood, increase gravel retention, and reduce sedimentation of existing gravel, and increased frequency of resting pools during upstream migration. This project will address the limiting factors for summer steelhead including water quality and riparian condition.
