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.

Sandy River Dam Removal

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. 

Ridgefield NWR - Post Office Lake

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

Dairy Creek 1135 - Sturgeon Lake

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.
