Abstract: A major atmospheric river caused significant flooding in northwestern Washington and southwestern British Columbia in November 2021. When there is flooding in the Skagit basin, the US Army Corps of Engineers directs regulation at two reservoirs, Ross Dam and Upper Baker Dam, to reduce damages in downstream communities. During the November 2021 event, the reservoirs provided significant benefit by reducing the peak flow in the river up to 40%. Sonja Michelsen will present on the hydrology of the November flood event and the Corps’ role in flood risk reduction through reservoir regulation.

Bio: Over the past six years at the Corps, Sonja has focused on riverine flood risk reduction. She has managed water in reservoirs across the northwest and conducted numerous hydrologic and hydraulic analyses. Sonja grew up in the desert southwest, an experience that highlighted the importance of water, and received her B.S. in Ecological Engineering from Oregon State University. She currently lives in Seattle.
