Construction phase for a restoration project on Haskel Slough, a ~2.4 mile long (71 acre) side channel of the Skykomish River near Monroe, Washington. The slough provides critical spawning and rearing habitat for Chinook salmon and other listed fish species. There is a deteriorating training dike at the upstream end of the slough that prevents surface flow connectivity with the exception of extreme flood events. The goal of the future restoration project is to enhance juvenile salmon rearing and flood refugia habitat in Haskel Slough by modifying the inlet dike to promote increased connectivity, water quantity and water quality. Additional project benefits will include floodplain water storage, and prevention of safety and infrastructure damage resulting from catastrophic dike failure.
