46. Every dam owner must, from the dam commissioning date, establish and maintain a logbook in which activities and important events relating to the safety of the dam are recorded in chronological order.
In addition to the information required under section 21 of the Act, the logbook must contain
(1)  a brief description of all inspection activities carried out, indicating the reservoir level at each inspection;
(2)  a brief description of every safety review conducted; and
(3)  a description of any maintenance, repair or structural alteration work to the dam.
The logbook must also contain, where applicable,
(1)  a description of unusual natural events, such as earthquakes, a flood with a 20-year or more recurrence interval, rainstorms or windstorms, landslides, floating islands, and ice conditions;
(2)  a description of events caused by human activity, such as vandalism or sabotage or work carried out near the dam, that could affect its stability;
(3)  any deviation from operational constraints relating to dam safety established at the time of dam design or in a safety review, in particular with respect to the full supply level and to filling and drawdown speeds;
(4)  a description of special activities, such as behaviour tests or investigations; and
(5)  a description of operations that have been carried out, excluding regular flow controls.
The owner of an existing dam must enter in the logbook, to the best of the owner’s knowledge, the actions that have been taken and the significant events that have occurred from the dam commissioning to the date of coming into force of the Act.
