Project Summary

Project 2010-005-00 - Abernathy Tidal Restoration
Project Number:
Abernathy Tidal Restoration
The Washington Department of Fish and Wildlife (WDFW) -- in partnership with BPA -- will conduct ecosystem restoration within the tidal reaches (RM 0.0 – 0.56) of Abernathy Creek. The purpose of this Estuary Habitat restoration is to provide enhanced adult holding and spawning habitat and juvenile salmonid rearing habitat -- to help recover ESA-listed anadromous fish species within a naturally functioning estuary ecosystem. Under Phase 3 of this Project, WDFW will implement the "Construction" of the Abernathy Tidal Restoration preferred alternatives -- as a Washington Estuary Habitat MOA Project. (Phase 1 was Feasibility Study and Phase 2 was Design).

Anadromous salmonid species in the Abernathy Creek watershed include fall chinook salmon, chum salmon, coho salmon, winter steelhead, and sea-run coastal cutthroat trout. Salmon and steelhead numbers have declined to only a fraction of historical levels. In addition to anadromous salmonids, depleted stocks of Pacific lamprey, Eulachon (proposed for listing), and green sturgeon (threatened) also exist in Abernathy Creek.

Species ESU ESA Status Historical Population Size Recent Numbers
Fall Chinook LCR Chinook Threatened 5,000-7,500 300-400
Chum LCR Chum Threatened 6,500-40,000 50-100
Coho LCR Coho Threatened 10,000-30,000 unknown
Winter Steelhead Coastal Steelhead Not listed 2,000 50-500
Sea-Run Cutthroat -- Not listed unknown <15
Pacific Lamprey -- Not listed unknown unknown
Green Sturgeon Southern DPS Threatened unknown unknown
Eulachon LCR Proposed Threatened unknown unknown
Phase 3 Construction Tasks:

A. Conduct the Construction Tasks from July 15, 2012 through October 31, 2012.
a. Mobilization; delivery of equiqment, and storage of logs and construction materials on-site.
b. Survey and flag key design elements, including wetland protection.
c. Renovate access road and remove trees to be used for large wood structures.
d. Put any sediment reduction structures and coffer dams in place, as needed to protect stream environment and ESA fish.
e. Excavate blind channels.
f. Build hummocks with soils excavated from channels.
g. Haul excavation spoils offsite, including road bed rock and old boat ramp materials.
h. Build large wood structures and engineered log jams.
i. Conduct plantings and other revegetation actions.
j. Demobilization.
B. Develop a monitoring plan for revegetation, and a long-term Operations and Maintenance Agreement with BPA.

Description: This is a photo of the gravel road at the top of the floodplain near Abernathy Creek that headed down to the collapsed boat ramp prior to removal in 2012.



Location: 46.194468° N, -123.165435° E

Dimensions: 1536 x 2048

Description: This photo was taken looking south down the eastern Blind Channel A that was constructed in an area that previously had a gravel road down the middle. This channel was excavated within the floodplain and LWD added for fish.



Dimensions: 648 x 486

Description: This is a view of Abernathy Creek at high flow when the tides are coming into the creek just upstream of the old collapsed boat ramp where the channel braids naturally. The dominate vegetation was reed canary grass



Location: 46.192150° N, -123.166825° E

Dimensions: 2048 x 1536

Description: This photo was taken during the initial stages of construction at Abernathy Creek following the removal of the old boat ramp that was replaced with this large engineered log jam feature. Several blind channels were excavated, the areas secured with LWD and planted with native vegetation.



Dimensions: 1296 x 972
