Table 5.7.2 Potential environmental watering for the Loddon River system under a range of planning scenarios
5.7 Loddon system
 Planning scenario
   Drought
   Dry
   Average
   Wet
  Expected river conditions
 • Negligible contributions from unregulated reaches and tributaries of the Loddon River, consumptive water deliveries in the irrigation season
• Reduced passing flows in autumn/ winter likely
 • Small inflows from unregulated reaches and tributaries of the Loddon River contributing to low flow, consumptive water deliveries in the irrigation season
 • Natural flow will provide low flow and multiple freshes, most likely in winter/ spring
• Consumptive water deliveries in the irrigation season
• No spill likely
 • Spills from Loddon system storages will provide extended- duration high flow and overbank flow most likely in late winter/spring
 Expected availability of water for the environment1
   • Up to 15,600 ML
   • 17,700 ML
   • 20,700 ML
   • 20,700 ML
   Loddon River (targeting reach 4)
   Potential environmental watering – tier 1a (high priorities)
 • One to three summer/autumn freshes
• One winter/spring high flow
• Summer/autumn low flow
• Winter/spring low flow at
lower magnitude (accumulating passing flows savings)
 • One to three summer/autumn freshes
• One winter/spring high flow
• Summer/autumn low flow
 • One to three summer/autumn freshes
• One winter/spring high flow
• Summer/autumn low flow
• Winter/spring low flow
 Potential environmental watering – tier 1b (high priorities with shortfall)
  • Summer/autumn fresh delivered at upper magnitude
• Winter low flow delivered at upper magnitude
  • Winter low flow delivered at upper magnitude2
• One autumn high flow
   • One autumn high flow
 Potential environmental watering – tier 2 (additional priorities)
   • One autumn high flow
