Supply measure projects
Supply projects are improved ways to manage the Basin’s rivers to more efficiently deliver water for the environment.
Supply measure projects include environmental works, such as building or improving river or water management structures, and changes to river operating rules to achieve environmental outcomes with less water.
The South Australian Government submitted to the Murray-Darling Basin Authority (MDBA) a range of supply projects:
- The Living Murray projects: Chowilla, Pike, and Katarapko floodplains
- Flows for the Future
- Riverine Recovery Project: Yatco Lagoon and the Phase 1 and Phase 2 Wetlands Project
- South Australian Riverland Floodplain Integrated Infrastructure Program (SARFIIP) - Pike and Katarapko Floodplain Project
- South East Flows Restoration Project
- SA Constraints Measures Project
Together with New South Wales and Victoria, South Australia is also jointly responsible for implementing the Enhanced Environmental Water Delivery Project and The Living Murray environmental works and measures program.
Sustainable diversion limits in the Southern Connected Basin can be adjusted up and down through these projects, providing flexibility when needed. Supply measure projects (commonly called ‘offset projects’) allow diversion limits to be increased when they can achieve the Basin Plan’s target environmental outcomes with less water through improved ways to manage the Basin’s rivers to more efficiently deliver water for the environment. They include environmental works (such as building or improving river or water management structures), changes to river operating rules, and activities that address constraints to the delivery of water for the environment.
The Basin Plan requires the MDBA to undertake a reconciliation of supply measure projects in 2027 to determine if the package of projects have the potential to deliver the expected environmental outcomes.
