Significant hazard dams are dams where failure or misoperation results in no probably loss of human life but can cause major economic loss, environmental damage or disruption of lifeline facili-ties Maine law requires they be inspected every four years.

High hazard dams are dams where failure or misoperation will probably cause loss of life Maine law requires they be inspected every two years.

Where there is a dam inspection date but no condition notes, this indicates that the Army Corps of Engineers inventory noted the existence of a report, but not its contents.
