Description    


Lower Columbia River FEG Upper Washougal River Restoration- Phase II project addressed degraded floodplain conditions and functions identified by the LCFRB (LE) and WDFW as limiting salmon and steelhead production in the upper watershed. The project treated specific reaches of the mainstem Washougal River between RM 18 to RM 22 that had become deeply incised in a bedrock channel due to log drives and catastrophic forest fires in the late 1800’s and early 1900’s. The project directly benefitted a primary population of ESA listed summer steelhead and Fall chinook, as well as contributing populations of ESA listed winter steelhead and coho salmon. Other species present in the treatment reaches include resident cutthroat and rainbow trout, mountain whitefish and Pacific lamprey.

LCFEG installed 7 large logjams and over one hundred large diameter logs to restore channel function that was limiting production of salmonids. The logjams were installed to split or redirect flows resulting in altered hydraulic conditions resulting in sediment deposition which reduces wetted channel width. At the same time these large structures create a velocity refuge for all fish attempting to over winter in the bedrock confined channels where the structures were installed. Over 100 large diameter single logs were installed individually or stacked to increase elevation. These logs were very successful in capturing gravels and redirecting flows up to OHW level. Adult chinook, coho and steelhead use these new gravels extensively for spawning purposes and juvenile fish of all species use the diverse rearing habitat created by the high density of logs found in the treatment areas. Logs placed in lower Dougan creek have resulted in substantial sediment deposition at the foot of an otherwise impassable chute which may open another five miles of habitat to steelhead.

The structures were designed by LCFEG staff with technical input received from Pat Powers and Tim Abbe. Watters Excavation provided heavy equipment needed to place the logs in the river per LCFEG staff direction. College interns and offender crews from nearby Larch Correctional facility provided thousands of hours of labor to secure the logjams. Retired engineer and LCFEG board member Ed McMillan provided technical assistance. Clark Public Utilities Environmental Services manager and LCFEG board member provided low cost riparian plants and technical assistance. Skamania County, DNR and Longview Timber LLC provided access to their river front properties where the project was implemented.







Project Benefit    


The goal of the project is to improve instream morphology and habitat in salmon bearing streams. The objective of the project is to increase instream cover, spawning, and resting areas.
