The next Science on Tap at the Kiggins Theatre is 7 p.m. Sept. 11, “Un-Damming the Klamath: River Health as Defined By Its Ecosystems and Its Peoples.” Tickets are $15 to $45 at kigginstheatre.com/movie/science-on-tap-un-damming-the-klamath. In 2023, work began on removing one of four dams along the Klamath River – the world’s largest dam removal – after decades of activism finally found success. Learn more about the Klamath River dam removals, ecosystem, and people in this Science on Tap, presented by Desiree Tullos, a professor in the Biological and Ecological Engineering Department at Oregon State University, and Bryan Tilt, professor of anthropology.
