July 2016 SNOQUALMIE WATERSHED FORUM TEN-YEAR STATUS REPORT 2005-2015 Real Progress, Real Challenges: Working Toward Salmon Recovery and Watershed Health The Snoqualmie Watershed Forum is a partnership of elected officials, citizens and representatives from conservation organizations supporting salmon recovery and ecological health in the Snoqualmie and South Fork Skykomish Watersheds. Member governments include King County, the Snoqualmie Tribe, Tulalip Tribes, the cities of Duvall, Carnation, North Bend and Snoqualmie, and the Town of Skykomish. Since 1998, the Forum and its many partner organizations have worked to protect and restore salmon habitat and improve overall watershed health through collaborative action. From 1998-2005, the Forum played a key role in developing the Snohomish River Basin Salmon Conservation Plan, and since that time has led its implementation in the King County portion of the basin. The Forum’s work is funded by contributions from its member governments, as well as grants from the King County Flood Control District. In 2015, Forum member governments signed an interlocal agreement that renews this partnership through 2025. 3 I INTRODUCTION 4 I HOW ARE SALMON DOING IN OUR WATERSHEDS? 8 I HABITAT RESTORATION: PROGRESS AND CHALLENGES 14 I PROTECTING EXISTING HABITAT IS ALSO CRITICAL FOR FISH 16 I MONITORING EFFORTS TELL US ABOUT THE WATERSHED AND OUR RECOVERY WORK 18 I SUMMER 2015 TEMPERATURE STUDY MAY HOLD LESSONS FOR THE FUTURE 20 I WORKING ON PRIORITIES FOR FISH, FARMS AND FLOODS 22 I SUCCESSES AND FUTURE CHALLENGES 2 SNOQUALMIE WATERSHED FORUM Ten-Year Status Report 2005-2015 Skykomish Snoqualmie The encouraging gains made through restoration are still being outpaced by habitat KING COUNTY loss and degradation throughout Puget Sound.
