Allocations & availability

Based on water sharing plans, the department ensures the available surface and groundwater resources are shared equitably, and that water entitlements and allocations are secure and tradeable.

The volume of water licensed users can access is known as an available water determination (or water allocation). Allocations vary from year to year based on an individual entitlement. This is dependent on a range of factors including dam storage levels, river flows and catchment conditions.

  1. Water accounting

    The department continues to progress major reforms driven by commitments made under the National Water Initiative which recognised the need for a standardised, cohesive and comparable approach for water resource accounting, reporting and data systems.
