May 19, 2022 — The final hurdle is in sight and expected to be overcome, in the decades-long fight to remove four dams from the Klamath River and hopefully allow restoration of the river’s Chinook salmon population which was once the third-largest in the country, but in recent years has plummeted by as much as ninety-eight percent. The four dams were built between 1903 and 1967 as part of PacifiCorp’s Klamath Hydroelectric Project and are now obsolete. Removing them will provide native migratory fish, like Chinook salmon, access to larger spawning grounds. It will also help restore the natural flow of the river, providing innumerable benefits to the entire ecosystem.
The repercussions that an exhausted river system with a dramatically declining salmon population can deliver are far-reaching and staggering. The slow-moving, warm water gives rise to parasites, like Ceratonova Shasta, which reaches unhealthy levels in this environment and begins to infect and kill the salmon. In addition to parasites, the higher water temperatures are also a deadly threat to the salmon that are necessary for the overall health of the river. After salmon return to the river to spawn and die their bodies provide key nutrients to other organisms in the river. This includes the trees that grow along the riverbanks whose roots help to prevent erosion and to maintain the structural integrity of the riverbank. The Native American Tribes in the Klamath Basin are also heavily dependent on the Chinook salmon, both culturally and for sustenance. Subsistence salmon fishing is a way of life for tribes like the Yurok and the Karuk. Along with the salmon and the river, their way of life is dying.
