As with any other structure, dams require regular inspections to identify and prevent any damage or deterioration of its many components.

Inspections can range from those required by dam safety agencies, those required by the owner and other stakeholders, as well as general observations recorded by operations and maintenance staff. Observations from inspections help build a performance history of the dam spanning different seasons and consecutive water years against which future observations can be compared to identify any changing conditions.
