Clatsop County Estuary Restoration Project Proposed

by CBB Staff
Columbia Basin Bulletin - May 2, 2003

The U.S. Army Corps of Engineers is proposing a $900,000 restoration effort to improve about 10 miles of salmonid habitat near Brownsmead, Ore.

The project, sponsored by Clatsop County Diking Improvement Company No. 7, would improve the connection of Blind and Sapsal sloughs to the Columbia River through the installation of new or improved tide gates and culverts.

The Bonneville Power Administration and Columbia River Estuary Study Taskforce are assisting with local funding and coordination. Work would begin in September 2003 and take about six weeks.

The Corps has prepared an Environmental Assessment to address environmental impacts associated with the proposed work.

In 1938, the Corps of Engineers made substantial improvements to the levees for the diking districts. Between initial private and subsequent Corps efforts, the Brownsmead area was severed from the tidal actions of the Columbia River estuary.

The proposed project would restore salmonid access to and improve egress from 9.6 miles of former off-channel rearing and resting habitat through improved culverts and tidegate installation. Additional rearing and resting habitat would be available in the numerous small channels that dissect the area. Access for adult salmonids to Anderson Creek for spawning also would be improved.

The proposed action includes the following elements:
