This study evaluates the survivorship of planted trees at the Elysian Meadows restoration site with and without tree shades. With the increase of drought associated with climate change, the Skagit River System Cooperative is researching new strategies to overcome challenging … Continued
This study evaluates the one-year survivorship of deep-planted cottonwood poles installed by the Skagit River System Cooperative at the Skiyou Island Restoration site. With increasing drought associated with climate change, we are researching new strategies to overcome challenging growing conditions, … Continued
In the last century, average temperatures have risen in the Pacific Northwest and models predict additional increases over the next decades. The Office of the Washington State Climatologist (2024) recorded a 3.3 °F increase in Washington and a 3.6 °F … Continued
Human-made fish passage barriers have been identified as one of the leading contributors to aquatic habitat fragmentation (Sheer & Steel 2006). Salmonids and aquatic life rely on complex, continuous habitat to support population health, abundance, and reproductive success (Flitcroft et … Continued

Conservation and recovery efforts for depressed populations of wild Chinook Salmon Oncorhynchus tshawytscha are improved by detailed classifications of basic natural history traits for juveniles across habitats. The Skagit River system in northern Puget Sound provides a unique opportunity to study the … Continued
Estuaries provide rearing habitat for some juvenile ocean type Chinook Salmon. To gauge the importance of this habitat and characterize its use in the Skagit River, we calculated the respective percentages of juvenile and adult populations represented by juvenile life … Continued
This monitoring and adaptive management plan provides guidance for implementing effectiveness monitoring and adaptive actions for the Milltown Island restoration project in Skagit County, Washington being implemented by Washington State Department of Fish and Wildlife. The monitoring and adaptive management … Continued
The 2005 Skagit Chinook Recovery Plan (SCRP) was written in response to the 1999 threatened listing of Puget Sound Chinook Salmon under the Endangered Species Act. The SCRP includes recovery strategies with candidate actions for geographic areas associated with specific … Continued
Despite decades of restoration work, Chinook Salmon Oncorhynchus tshawytscha in the Pacific Northwest remain under the protection of the U.S. Endangered Species Act (ESA). Chinook Salmon in the Skagit River basin play a vital role in the abundance and recovery of the … Continued
This project plan provides a description for implementing effectiveness monitoring at the Britt Slough restoration project and at the South Fork Dike Setback Phase 2 restoration project in Skagit County, Washington. The project plan includes brief descriptions of the following: … Continued
The success of pinniped (seals and sea lions) recovery in Puget Sound has potential impacts on commercially and culturally important fish species, such as Pacific Salmon. Skagit River Chinook Salmon (Oncorhynchus tshawytscha) are listed as Threatened under the Endangered Species … Continued
Skagit River Chum Salmon escapement methodologies were originally developed in 1976 and 1977 (Hendrick 2003). The methodology was based on mark-recapture studies to determine distribution and proportional abundances along the Skagit River that were used to established six “index” reaches. … Continued
Habitat restoration planning and design can be informed by information on spatial patterns in habitat use, which can be obtained from temporally and spatially extensive monitoring efforts. Using records from long-term monitoring in four tidal deltas, we modeled how landscape … Continued
In 2018, the Skagit River System Cooperative (SRSC) formed the Skagit Culvert Working Group together with project partners Skagit County, the Skagit Fisheries Enhancement Group, and the Upper Skagit Tribe, to complete the initial phase of a project to update … Continued
