Context

The popular image of dam removal features a massive concrete wall tumbling into a western canyon to save the salmon. But in a 16 October 2026 piece for Smithsonian Magazine, the focus shifts to New England, where thousands of small, obsolete mill dams still choke local streams. The story tracks the neighborhood-level battle to tear down these colonial-era relics and let river herring return from the sea. It pauses on a surprisingly stubborn political question: why do towns fight so hard to keep the stagnant ponds of the industrial revolution instead of letting a river run free?
