About the Event
Session 1 of a three-webinar series interacting with experts on the Green-Duwamish Watershed. Participants will work with Nik Novotny, a Fish Biologist from Tacoma Water to explore the historic relationship between farming, flooding, and salmon habitat in the Green Duwamish Valley with a focus on the consequences of building Tacoma's Diversion Dam and Howard Hanson Dam. How and why were the original dams constructed? What happened to salmon populations when they were completed? Is there a plan for engineering fish passage? How would you do it? The PBL entry event for this integrated unit of study is to engineer, fund, and build fish passage around Howard Hanson Dam and to predict what would happen to salmon and Orca populations once in place.
