Wallacut River Acquisition & Restoration

This project permanently protects113 acres of forested wetland habitat at the confluence of the Wallacut River and Baker Bay (Columbia River mile 3), a back water area of the lower Columbia Estuary.  The project site includes numerous tidal channels and sloughs, some now hydrologically disconnected from the Columbia by the installing flood control structures.  Future restoration concepts include removing tide gates and culverts to re-establish tidal influence, removing invasive plant species and restoring the native plant community.

Milton Creek Riparian Planting

This project installs a diverse mix of native trees and shrubs in a 35 to 100 foot buffer along one mile of Milton Creek, in order to benefit resident Coho, Chinook, lamprey, cutthroat trout and steelhead.  The project is located several miles up Milton Creek, a Columbia River tributary that enters Multnomah Channel near the entrance to Scappoose Bay.

This project received non-Estuary Partnership funding, but was co-sponsored by the Estuary Partnership.

Louisiana Swamp

Louisiana Swamp project restores 35 acres of tidal wetland habitat

In August 2013 the Lower Columbia Estuary Partnership, Lower Columbia River Watershed Council, Columbia Soil and Water Conservation District and US Fish and Wildlife Service began moving earth to restore 35-acres of wetland habitat at the “Louisiana Swamp” site on the lower Columbia River, 4.5 miles west of Clatskanie, OR. The collaborative partnership with the property manager, GreenWood Resources, Inc.

Kloppman, Large Wood Debris Installation

This project installs 53 pieces of large wood into the stream and riverbanks to enhance in-stream habitat and restore spawning and rearing habitat for Coho, cutthroat trout, steelhead, and lamprey to 1,800 feet of the Clatskanie River.  The project site is located several miles up the Clatskanie River outside the lower Columbia floodplain.

This project received non-Estuary Partnership funding, but was co-sponsored by the Estuary Partnership.

 

Horsetail Creek Floodplain Restoration

The Lower Columbia Estuary Partnership, U.S. Forest Service, and partners completed construction of fish passage and salmon habitat improvements within the historic Columbia River floodplain in September 2013. Construction crews, heavy equipment, and helicopters worked in the vicinity of Horsetail and Oneonta Creeks, five miles west of the Bonneville Dam, for two months. Revegetation efforts at the site are on-going. 

Honeyman Creek

This project restores hydrologic connection to 58 acres of wetland and 1.6 miles of slough by replacing three existing culverts with bridges and installing an additional culvert at a disconnected slough.  The floodplain site is located on the Malarkey Ranch south of Scappoose Bay in the Scappoose Bottomlands.  The project addresses a number of unimproved road crossings that traverse numerous sloughs and channels.  These crossings limit the site’s tidal connectivity with the Columbia River and fish access to the floodplain.

Hardy Creek

This project completes a feasibility study to evaluate different restoration options within lower Hardy Creek.  The site is located near the confluence of Hardy Creek and the Columbia in the Pierce National Wildlife Refuge at Columbia River mile 142.  The lower portion supports salmonid populations, including spawning populations of chum, Coho, and steelhead.  However, it and its neighboring side channels have unstable banks and lack large wood and riparian vegetation.

Gnat Creek North

This project restores full tidal connection to 60 acres of diked tidal wetland through dike breaches; installs large wood, removes invasive species, and plants native species.  The project site is located on the west bank of Gnat Creek 0.6 miles upstream of its confluence with Blind Slough, and three miles upstream from the Columbia River confluence in Cathlamet Bay at Columbia River mile 26.  The site is privately owned and immediately downstream and across the creek from the Gnat Creek project completed in 2012.
