Toxic water quality in the Klamath River is a direct result of both upper basin agricultural development (the draining of wetlands and intense chemical use), and the presence of PacifiCorp's dams, creating warm, stagnant pools for algae to develop. Massive algae pools in Upper Klamath Lake.
<h2>Un-Dam the Klamath (#UnDamtheKlamath) is a social movement in the United States to remove the dams on the Klamath River primarily because they obstruct salmon, steelhead, and other species from accessing the upper basin which provides hundreds of miles of spawning habitat. The dams have also significantly harmed Hupa, Karuk, Klamath, and Yurok lifeways and communities. Copco #1, Copco #2, Iron Gate (all in California) and J.C. Boyle (in Oregon) are the four hydroelectric dams on the Klamath River that are being advocated for removal.</h2>
