Columbia River Temperature and Salmon Migration

Wednesday, May 8, 2019 @ 1:00 pm - 2:00 pm

Free

Martin Merz is a physical scientist with the Environmental Protection Agency (EPA) Region 10 in Seattle. His work is largely focused on river temperature issues, from a physical, biological and regulatory perspective. Approximately two to three million adult salmon and steelhead return from the ocean and migrate up the Columbia River each year. In his talk, Martin will focus on those fish who migrate during the summer months when Columbia River water temperatures are warm (and therefore adverse to their health and spawning success), and why cold water refuges from cooler tributary rivers are important. Time for questions to follow. RSVP: 206.297.0875.
