DESCRIPTION
The Brownes Creek Instream Habitat Restoration project sought to implement woody debris into a wood deprived system. Woody debris is essential for functioning riverine habitat systems. This project was located within the lower 2 miles of Brownes Creek, just upstream from the confluence with Hoko River in the westerly portion of Clallam County.
The Makah Tribe used this funding to restore formerly productive in-stream Chinook habitat in Brownes Creek that was destroyed when a massive debris torrent scoured the channel and valley walls up to 20-30 feet high, and removed all wood from the channel for a distance of two miles. The debris torrent initiated from a plugged culvert and deep road-fill failure on Washington State lands and was amplified by another deep fill a mile downstream on private timberland. Peak Chinook spawner counts dropped from an average peak live count of more than 36 fish per mile during the period 1997-1999 to zero in 2000, and 6 in 2001.
A large amount of wood was scoured from the channel and deposited outside of the bank-full width. The project moved the wood back into the stream using winches, a log loader, or a swing-yarder, depending on location. Additional wood was added where the creek is accessible from the road. Approximately one mile of stream was directly treated, and additional stream segments were seeded at crossings. Channel disturbance was minimized by walking equipment on wood or large swamp mats when near or in the channel.
The tribe placed wood in Brownes Creek throughout the two-mile reach. Over 10 log jams were passively created, up to 100 key-piece-sized LWD pieces were introduced, up to 1,000 individual LWD pieces were introduced, up to 10,000 conifer trees (spruce and cedar) were planted, and over 500 pounds of grass seed were planted. The wood was not cabled nor otherwise artificially secured. Some of it was buried in the bank but most has been allowed to move and position itself where the water has pushed it into distinct log jams.
These achievements will go a long way to rehabilitating the Chinook, coho, steelhead and cutthroat populations of Brownes Creek well into the future.
