Steelhead Haven Landslide Remediation

Project Description

One of the primary factors limiting Chinook production in the Stillaguamish watershed is fine sediment input before and during spawning and incubation. As stated by the Washington Department of Fisheries in the 1970's, "The principal factor limiting salmon production within the North Fork is sedimentation resulting from a major clay slide. Below that point, heavy silt deposits cover most of the gravel riffles, making them unsuitable for successful spawning and egg incubation. This condition also inhibits natural cycles of aquatic insect growth, reducing food production, and consequently low...
