Over a hundred years ago, the Klamath River was caught up in the audacious endeavor to tame the West. Engineers built the Klamath Hydroelectric Project over a 60-year period starting in 1902, harnessing hydropower for a growing region. Six dams were built on a 55-mile stretch of river flowing through the shrubby basalt landscape of Southern Oregon and Northern California. Within a few short decades, the dams came to be seen as part of a fixed landscape—inevitable even. But of course, infrastructure projects and landscapes aren’t fixed. Rivers change course, bridges collapse, and even mountains move—acts of God, or nature, or human failing.
