Summary of current water allocations
Below are tables summarising current water allocations for regulated river, unregulated river and groundwater water sources.
Allocations that are normally expressed in megalitres per unit share – for example high security, general security and aquifer access – are expressed in the tables below as percentages. One megalitre (ML) per unit share equates to 100% allocation, whereas 0.05 ML per share equates to 5% allocation.
Tables for the unregulated rivers and groundwater sources report by exception, that is, only those water source licence categories that did not receive full allocations are listed.
Carryover water
Water users may have access to unused water in their account carried over from the previous year. Carryover rules vary between water sources and between licence categories. Towns, domestic and stock, and most high security licence categories cannot carryover.
Drought stage
The current drought stage for each inland river valley is included in the table. These range from Stage 1 (Normal operations) to Stage 4 (Critical drought). The drought stage is determined in accordance with the critical trigger levels outlined in incident response guides (IRGs) developed by the department. Further information on the IRGs is available at extreme events.
