Dam Safety in Vermont

Vermont has 362 dams tracked in the National Inventory of Dams. Of these, 67 (18%) are classified as high hazard — meaning failure would probably cause loss of human life — and 131 are classified as significant hazard. Currently, 104 dams in the state have a condition assessment of poor or unsatisfactory, indicating recognized safety deficiencies.

The average dam in Vermont is 90 years old. Many of these aging structures were built before modern dam safety standards were established, which increases the importance of regular inspections and maintenance. The most common purpose for dams in Vermont is recreation, accounting for 190 of the state's dams.

The federal inventory is not every dam in Vermont. It includes dams rated high or significant hazard, plus low-hazard dams above a size threshold (taller than 25 feet holding more than 15 acre-feet, or taller than 6 feet holding more than 50 acre-feet). Small, older dams below that line are usually left out, even though they can still shape the streams around them. The state's own dam safety program often tracks many more, and it is the agency that inspects most of them.
