SA Constraints Measures Community Infrastructure Investigation

What is being decided?

To further enhance environmental outcomes and improve community resilience to River Murray high flows, the South Australia Constraints Measures project is seeking community input to help develop future project proposals that balance environmental, social and economic outcomes, while reflecting the needs and priorities of communities and businesses.

We are asking the community to:

  • Identify local opportunities that would benefit from infrastructure upgrades or impediment removal.
  • Provide feedback on what information and tools would be useful in self-managing the effects of high flows on their land or business.
  • Highlight locations they know to be impacted by high flows up to 80 GL/day.


Background

The South Australia Constraints Measures project is working to remove constraints, or barriers, that limit the delivery of environmental water along the River Murray in South Australia, to improve the health of its floodplains and wetlands.

While the main goal of relaxing constraints is to provide greater potential for environmental flows to floodplains and end-of-system, the SA Constraints Measures project is also working to improve access, where possible, to the river and facilities for water managers, communities and landholders during natural high flow events.

High flow events that enable flows over riverbanks are essential for the health of the river system, and planning controls developed as a result of the 1956 flood event have guided construction of infrastructure on the floodplain to minimise impacts of future high flows and floods. However, during high flows, inundation of some riverfront land, jetties, marinas, pontoons and public roads can occur.

The SA Constraints Measures project is investigating ways to mitigate the effects of high flows on infrastructure and communities, including improving access for communities and landholders during natural high flow events.


How to get involved

  • Find out more by reading the consultation guide.
  • Use the interactive map to drop a pin and comment (with optional photo) to identify either of the following:
    • in-scope opportunities within your local area for infrastructure upgrades or impediment removal
    • locations impacted by high flows up to 80 GL/per day.
  • Complete the online survey to provide feedback on potential SA Constraints Measures project works.

For more information on the SA Constraints Measures project, please visit www.environment.sa.gov.au/Constraints

This stage of the consultation (Phase 1) is open until 5pm Friday 20 February 2026.

Next steps

Feedback provided will help us understand the effects of high flows on the community and will be used to inform future infrastructure planning, including the SA Constraints Measures project proposal for future funding (due for submission December 2026) to deliver potential future projects.
