Dam protection and water after fire

Fire can remove the vegetation that protects dams and waterways. This can increase erosion, ash runoff and water quality issues, particularly after rainfall.

What to do after fire

  • Check dam walls and spillways for damage, cracking or erosion
  • Remove debris from spillways and inflow points
  • Fence dams where possible and pump water to troughs
  • Watch for dark, smelly water or scum – these can indicate poor water quality

Before rain

  • Install simple sediment traps or silt fencing above dams and along drainage lines
  • Leave burnt vegetation and fallen timber in place to slow water flow

If water was taken for firefighting

You may be eligible for free replacement water. Contact the VicEmergency hotline on 1800 560 760 to check eligibility and whether the program is still running.

Who to contact for more information

Land, waterways and weeds

Dams and dam safety

  • DEECA (Department of Energy, Environment and Climate Action) is the state regulator for dam safety in Victoria and sets the rules and standards under the Water Act 1989.
  • Goulburn Valley Water looks after the dams and reservoirs it owns and operates, including drinking water storages, and can provide advice on dams in its service area.

If you are unsure who manages a specific dam, start with Goulburn Valley Water, who can direct you to the appropriate agency if needed.
