Travelling across North America, DamNation investigates the growing change in national attitude from strange pride in big dams as domineering engineering projects, to the growing truthful awareness that dams have always been the great killers of rivers, wildlife, the salmon, the forests, coastlines, watersheds. Life is bound to water and health of rivers, and now, dam removal in many forms—including Monkey Wrenching—is reclaiming that life and spreading. Where dams come down, rivers come back, allowing the salmon to return after decades of being concreted out. By making firsthand unexpected discoveries moving through rivers and the landscapes altered by dams, DamNation presents a much-needed metamorphosis in values, from conquest of the natural world to knowing ourselves as part of nature; to respect, and be humbled. With over two million dams in North America alone—75,000 of them over six feet tall—there's much work to be done. Let's get to it.
