A third of the State’s divertible water resources are brackish or saline and no longer suitable for drinking, with a further 16% of marginal quality.
In addition, with stream salt loads likely to increase five-fold over the next 50 years it is important to know the salinity status of rivers in the South West drainage division. This program determines the salinity status and trends for rivers within the Avon, Northern Agriculture, South Coast and South West NRM regions.
The key objectives of this component are to:
- Identify stream salinity, flow status and trends for rivers within four NRM regions of Western Australia.
- Present key information to stakeholders and the community (in the form of maps and brochures).
