About water availability
We use the rules in water sharing plans to distribute available surface and groundwater resources sustainably and fairly. We also ensure that water entitlements and allocations are secure and tradeable in accordance with plans and rules.
A water allocation, or available water determination, is the proportion of a licensed water user’s entitlement credited to their water account for use. Allocations vary over time based on the water available in dams, river flows and the prevailing catchment and weather conditions.
