Table 5.6.2 Potential environmental watering for the Campaspe River under a range of planning scenarios
 Planning scenario
   Drought
   Dry
   Average
   Wet
  Expected river conditions
 • Little or no natural flow
• No passing flows in winter
• Operational water deliveries
 • Some natural flow
• Increased passing flows
• Operational water deliveries
 • Some natural flow
• Increased passing flows
 • Some natural flow
• Increased passing flows
• Spills from storage
 Expected availability of water for the environment
   • 9,700 ML
   • 20,300 ML
   • 35,400 ML
   Potential environmental watering – tier 1a (high priorities)
• Summer/autumn low flow
• Reduced winter/spring low flow
• Year-round fresh (if needed)
  • Summer/autumn low flow
• One winter/spring fresh
• Winter/spring low flow
• One to three Summer/autumn freshes
• Year-round fresh (if needed)
 • Summer/autumn low flow
• One to two winter/ spring freshes
• Winter/spring low flow
• One to three Summer/autumn freshes
• Year-round fresh (if needed)
 Potential environmental watering – tier 1b (high priorities with shortfall)
  • Increased magnitude winter/spring low flow
 • N/A
  • N/A
 Potential environmental watering – tier 2 (additional priorities)
  • One winter/spring fresh
 • Additional winter/ spring fresh
  • N/A
 Possible volume of environmental water required to achieve objectives1
   • 9,700 ML (tier 1a)
• 3,200 ML (tier 1b)
• 4,100 ML (tier 2)
  • 18,200 ML (tier 1a)
• 4,100 ML (tier 2)
   • 27,700 ML (tier 1a)
  1 Environmental water requirements for tier 2 actions are additional to tier 1 requirements.
