 5.5 Broken system
Table 5.5.4 Potential environmental watering for lower Broken Creek under a range of planning scenarios
 Planning scenario
   Drought
   Dry
   Average
   Wet
  Expected river conditions
 • No unregulated flows in winter
• No unregulated flows throughout the irrigation season (mid-August to May)
• No diversion of unregulated Murray River flow available
  • Some unregulated flows in winter
• No unregulated flows throughout the irrigation season (mid-August to May)
• No diversion of unregulated Murray River flow available
  • Unregulated flows in winter/spring
• No unregulated flows during October to May (except
for an occasional unregulated fresh in spring)
• Diversion of unregulated Murray River flow available during mid-August to October
  • Unregulated flows in winter/spring
• No unregulated flows during November to May
• Diversion of unregulated Murray River flow available during mid-August to November
  Potential environmental watering – tier 1 (high priorities)1
  • Year-round low flow
• Winter/spring/summer/autumn high flow
• Winter/spring freshes
  Possible volume of environmental water required to achieve objectives
  • 44,800 ML
   • 45,680 ML
   • 55,650 ML
   • 43,150 ML
  Priority carryover requirements
  • 5,000 ML
  1 Tier 1 potential environmental watering for lower Broken Creek 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 lower Broken Creek
