HALLOWELL — A new report says more than half of Maine’s high-hazard dams are overdue on their mandatory inspections.

The Maine Center for Public Interest Reporting says 24 of Maine’s 93 dams are classified as “high hazard potential,” meaning failure or incorrect operation could result in loss of life. The other 69 dams are “significant hazard dams,” meaning a failure could cause property or environmental damage.

The center says records from the Maine Emergency Management Agency show 15 of the high-hazard dams are overdue on being inspected. State law requires inspections every two years.

The state doesn’t have any inspection records for six of the dams, either because they haven’t been inspected or because of poor record-keeping.

The agency could produce reports showing on-time inspections for only three of the high-hazard dams.
