All declared dam owners must produce a written risk report on all foreseeable risks to the dam:

• at least once every 5 years, and
• if you propose to make a major change to the dam, at the time the change is being designed that takes the proposed change into account, and
• if required to do so by Dams Safety NSW.

The risk report must use the risk management framework under clause 14 of the Dams Safety Regulation 2019, and set out

• the societal risk rating and the highest individual risk rating of the dam calculated using the Societal and Individual Risk Rating Methodology, and
• an explanation of any assumptions used when making that calculation.
