 5.2 Victorian Murray system
Table 5.2.15 Potential environmental watering for Lindsay, Mulcra and Wallpolla islands under a range of planning scenarios
 Planning scenario
   Drought
   Dry
   Average
  Wet1
  Expected conditions
 • Year-round low
flow in the Murray River and no natural floodplain wetting. Weir pools will be drawn down below full supply level year- round. Substantial wetland drying will occur.
 • Rare high-flow events in the Murray River and no natural floodplain wetting. Weir pools will be drawn down below full supply level year- round. Substantial wetland drying will occur.
 • Short periods of high flow, most likely in late winter/ spring, providing minor wetting of the floodplain. Weir pool levels raised in winter/spring and drawn down in summer/autumn.
 • Long periods of
high flow, with
major spills from storages resulting in widespread wetting of the floodplain
and wetting of most wetlands. Weirs would be removed to allow the passage of natural flows.
