The largest dam removal project in United States history is underway along the California-Oregon border — a process that won’t conclude until the end of next year with the help of heavy machinery and explosives.

    I don’t think @[email protected] said hydropower is no longer needed. They just said there’s no need for so many dams anymore, and I think that’s correct in this case.

    A lot of these older and extremely underpowered dams were built in important riverways. They decimated salmon runs but produced only small amounts of power in return. For a recent example, Elwha Dam removal in Washington State comes to mind. It and another dam produced only 38% of the electricity needed to operate one sawmill, but it killed salmon habitats.
