A Pennsylvania dam built 150 years ago to power a mill is now being removed, restoring free-flowing water

The removal of Hoffman's Mill Dam in Pennsylvania has revitalized Brandywine Creek, allowing it to flow freely once again. Built around 150 years ago, the dam no longer served any functional purpose and instead obstructed fish migration, accumulated debris, and intensified flooding risks. The removal was carefully planned and executed by a coalition of organizations to protect local wildlife.
