Acceptable flood capacity of referable dams
Safety standards are set for referable dams to provide protection to the downstream community from the effects of dam failure.
The Guidelines on safety assessments for referable dams (PDF, 1.6MB) describes the evaluation of dam safety risks at referable dams, whether those risks are acceptable and remediation of any identified deficiencies including recommended timelines for spillway upgrades and circumstances requiring a reduction of full supply level at a dam.
The guideline was previously titled Guidelines on acceptable flood capacity for water dams. The new guideline broadens consideration to the overall dam failure risk rather than focus solely on spillway capacity.
