Securing your future water needs: Harnessing carryover and other water products
30 April 2021
Key messages:
- Last summer’s La Nina reduced irrigation demand
- The MDBA active storage is at 45% (this time last year active storage was at 27%)
- Other storages are generally at or above average
- The Bureau of Meteorology climate forecast is currently neutral for the next 3 months (anything could happen in terms of rainfall and inflows)
- Major Victorian High Reliability water shares are expected to reach 100% in 2021-22 under average or wetter inflow scenarios
- Currently, around 500 GL is held in privately owned allocation accounts in the Victorian Murray system and about 500GL in the Goulburn system
- Approximately 650 GL likely to be carried over in the NSW Murray system and 565 GL in the Murrumbidgee system
- A Carryover Calculator is available for Victorian water systems to explore your unique on-farm carryover scenarios
A table that summarises carryover rules for major entitlement types in the sMDB is below:
| Entitlement type | Carryover highlights |
| Vic High Reliability | up to 100%, 5% loss, subject to spill risk, returned after declaration |
| Vic Low Reliability | up to 100%, 5% loss, not subject to spill risk* |
| NSW Murray General Security | up to 50%, no loss, forfeit future allocation above 110% |
| NSW M’bidgee General Security | up to 30%, no loss, forfeit future allocation above 100% |
*unless there is water allocated onto this entitlement
- When looking to secure water for the future, consider:
- Goals for the water secured – such as providing a low-cost input for annual crops versus security for perennial plantations
- Access to capital
- Exposure to risk such as the volume that could be allocated to you in a season, the market spot price and the potential for disputes
- Options to secure water include:
- Permanent entitlement or water shares
- Entitlement lease
- Forward allocation contracts (including options)
- Temporary allocation market
- Carryover (“parking” or using your own space)
- Other options that can be negotiated between a buyer and a seller
- Each option has its own benefits and risks
- Generally, using a combination of the above options is the best strategy.
