Key water management issues

While the natural flow of rivers and streams in the Sydney Central-Georges River catchment has been altered by water storages such as dams and weirs, the basin is considered an unregulated system. This is because there are no water storages owned and operated by State Water or the NSW Office of Water to provide water to licensed water users, such as farmers.

Alteration of the natural river flow and intensive urban and industrial development are key water management challenges. Specific issues include:

  • Water quality – pollution and algae and weed growth
  • Riverbank management – urban and industrial development
  • Environmental water – sufficient flows and freshes to maintain river health
  • Increasing demand for water – urban population and industry growth

Water sharing plans

To preserve water resources in river and groundwater systems for the long term it is critical to balance the competing needs of the environment and water users. Water sharing plans establish rules for sharing water between the environmental needs of the river or aquifer and water users, and also between different types of water use such as town supply, rural domestic supply, stock watering, industry and irrigation.

Water sharing plans in this catchment:

  • Greater Metropolitan Region Groundwater
  • Greater Metropolitan Region Unregulated River

Under the Water Management Act 2000 all water sharing plans are required to have performance indicators to assess whether the plans have been effective in meeting their objectives.
