In 2000, I was 18 years old and working at my first job with the Karuk Department of Natural Resources. That year, as we watched the Klamath River visibly thicken with neon green toxic algae, the Northwestern-based power company PacifiCorp announced it would be seeking another 50-year license for operation of its hydroelectric dams upstream. The four dams had been built in the 20th century to generate hydroelectric power, with, I believe, little forethought about the long-term consequences. It didn’t take contemporary science to tell us our problem was flowing from the dams. Their reservoirs were the same noxious color.
