 of what was to come. The gatekeeper's wife watched from their cabin as the dam exploded upward. Four riders galloped down the valley as fast as possible to warn people of the oncoming flood. Some residents fled to higher ground, while others refused to believe the awful news. Many never heard the warning. A 6 metres (19.7 ft) tall flood swept everything away. Damage totaled US$1 million and 144 people died.

Mill towns petitioned Boston for assistance. The legislators eventually granted $120,000 to rebuild bridges and roads, which set a precedent for a state government to provide direct assistance after a natural disaster. The disaster led to improvements in public safety. The Massachusetts legislature imposed standards for the construction, maintenance, and inspection of dams. Engineering of large-scale public projects had to meet state mandates. Engineers became academically-trained professionals. Four-fifths of the businesses in the Mill Valley were eventually rebuilt on their original locations. The mill owners gradually regained their financial standing and their place as pillars of society. Factories powered by the rushing Mill River continued to dominate life in the valley for another quarter century, until steam, and then electricity, replaced water power.
