Carryover allows water entitlement holders to take their unused water allocation in the following season. It provides all water users - irrigators, urban water corporations, and environmental managers – with greater flexibility to manage their own water availability between seasons.

Carryover is possible in the regulated water systems of northern Victoria, except for the Ovens system where storages are too small to support carryover, and in the Werribee water system in the south. Carryover is also allowed in some groundwater systems, and for bulk entitlement holders in the Wimmera.

Carryover rules

Carryover rules make sure that water carried over cannot unfairly impact on allocations to everyone’s water entitlements. Rules vary between water systems depending on how the volume of water entitlements relates to the size of the dams and how they are managed.
