Local Partners Help Salmon Return to Historic Tidal Wetland
Fisheries biologists have determined shallow tidal wetlands offer juvenile salmon a refuge from predators and a place to feed and transition from fresh to saltwater.
The juvenile salmon, also called smolts, will spend as long as 60 days resting and foraging in wetlands as they prepare for their long ocean migrations.
Ecologists say the re-opening of the tidal wetland is important to Columbia River fisheries since approximately 65 percent of the river’s historic estuary wetlands no longer exists. Other projects aim to restore hundreds of acres more habitat throughout the estuary.
Environmental experts from the Columbia River Estuary Study Task Force, or CREST, are leading the project with the Bonneville Power Administration providing project oversight plus a large portion of the $1.2 million needed for construction.
