Table 5.4.4 Potential environmental watering for the Goulburn wetlands under a range of planning scenarios
1 Tier 1 potential environmental watering for the Goulburn 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 Goulburn 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.
5.4 Goulburn system
 Planning scenario
   Drought
   Dry
   Average
  Wet
  Expected river conditions
 • Catchment runoff and natural flow into the wetlands are highly unlikely
 • Catchment runoff and natural flow into the wetlands are unlikely
 • Some catchment runoff and natural flow into some of the wetlands are likely, particularly in winter/ spring
 • Catchment runoff and natural flow
into the wetlands may significantly contribute to
water levels in the wetlands, particularly during winter/spring
