Undammed: Freeing Rivers and Bringing Communities to Life

Free-flowing rivers in the United States are an endangered species. With more than 500,000 dams in place, we've dammed and diverted almost every major river, straightening curves and blocking passage for fish and other aquatic animals, pushing many to the brink. Now a heartening new movement is helping to demolish harmful or obsolete structures and restore new life to rivers and the communities that depend on them. In doing so, it offers a pathway to undoing environmental harm to nature—and to ourselves.

In Undammed, environmental journalist Tara Lohan takes a clear-eyed look at the unexpected benefits of dam removal after centuries of dam-building. In helping to restore rivers, she argues, we're protecting our own communities by improving water quality, enhancing public safety, and boosting fish populations that feed people and restore rights for Native American Tribes. In Europe, where river barriers occur almost every half-mile, the US movement is spurring a rival effort to restore natural flow to rivers degraded by obstructions.

Undammed is an inspirational look at our changing relationship with the natural world, showing the cascade of benefits that come when we no longer turn our backs on rivers. And in helping to restore rivers, we're helping ourselves.
