Haskell Slough Salmon Habitat Restoration
Haskell Slough Salmon Habitat Restoration
Haskell Slough is located in Snohomish County Washington where native Pacific northwest salmon stocks are in decline. After 60 years of limited or no salmon production in a slough adjacent to the Skykomish River, 3 1/2 miles of old river bed was restored for salmonid use by excavating 6,000 feet of stream channel that connected 11 large existing groundwater-fed ponds. The new channels connect the system to the river at the downstream end of the project and have begun to restore salmon production to the slough.
