Table 5.2.9 Potential environmental watering for the central Murray wetlands under a range of planning scenarios
1 Tier 1 potential environmental watering for the central Murray wetlands is not classified as tier 1a or 1b because the water available for use is shared across various systems and it is not possible to reliably determine the supply specifically available for the central Murray wetlands.
2 Wetlands are listed in priority order for tier 1 and tier 2 under all scenarios.
3 Environmental water requirements for tier 2 actions are additional to tier 1 requirements.
5.2 Victorian Murray system
 Planning scenario
   Drought
   Dry
   Average
  Wet
  Expected river conditions
  • Catchment runoff and natural flow into the wetland are unlikely
  • Some catchment run-off and
natural flow into
the wetlands are possible, particularly in winter/spring
  • Low to moderate catchment run-off and natural flow into the wetlands are likely, particularly in winter/spring
  • Catchment run-off and natural flow into the wetlands is likely with potential widespread flooding in some wetlands, particularly winter/ spring
