The environmental consequences of dam failures has received considerable global attention in recent times. To help inform the design criteria, frequency of monitoring and inspections, requirement for emergency preparedness plans/emergency response plans, and other operational considerations, the Canadian Dam Association (CDA) uses a dam failure consequence classification system. The environmental component of the existing consequence classification system lacks a clear scientific basis and uses vaguely defined classification criteria.
