Across the northeastern United States, numerous small, often obsolete dams on streams and rivers are being torn down, reopening historic migration routes for river herring and other fish. The removals, less publicized than high-profile Western dam demolitions, are occurring piecemeal across the region as agencies and conservation groups target structures that block fish passage.
