Fish passage barrier removal, restore native vegetation, improve water quality, restore rearing and refuge habitat for Col River coho salmon, fall Chinook salmon, and Steelhead trout.

The project removes a 1930 era diversion dam across the main channel of the Sandy River near the confluence with the Little Sandy River. Implementation of the project restores flows to the east channel allowing natural physical/biological processes to occur in support of local and upstream ESUs. The project reconnects approximately 190 acres of the historical channel with the estuary.
This project will restore hydrologic connection from the Post Office Lake floodplain wetland with the estuary while protecting privately owned farmland. The objective is to re-establish access and improve wetland function to approximately 80 acres of shallow water habitat for juvenile salmonids. Project Site Acres = 80. This project is identified in the Fish & Wildlife Service Review of Conceptual Lower Columbia River Refuge Salmonid Restoration Projects
Lord Island - Channel modification to improve embayment circulation for about 335 acres of marsh/swamp and shallow-water habitat.
Fish passage barrier removal, restore native vegetation, improve water quality, and restore habitat for listed salmonids.
Project will address a naturally occurring levee breach along the Columbia mainstem. Will include a setback levee, and other elements
Tide Gate retrofit on National Wildlife Refuge near Cathlamet WA. increase tidal flushing and fisheries access to approximately 110 acres [need confirmation from the Corps on as-built acres/# of tidegates].
Bio-control agents are deployed to help slow existing stands of purple loosestrife. This exotic invasive plant species is spreading throughout emergent tidal marshes in the estuary.
This project aims to improve water circulation in Sturgeon Lake. The improvements to water circulation in Sturgeon Lake will improve access to the lake for juvenile salmon and trout from the Columbia River, providing seasonal over-wintering and rearing habitat. The project would also reduce the sedimentation occurring in the lake and may enhance water quality by flushing out nutrients and bacteria.
