Scenario planning
Table 3.7.4 outlines the potential environmental watering and expected water use under a range of planning scenarios.
The environmental watering regime for Reedy Lake and Hospital Swamps will be informed by the outcomes of an independent review of the lower Barwon wetlands watering trial 2016–17 to 2019–20, which is due to be completed early in 2020–21.
After the independent review of the lower Barwon wetlands watering trial is complete, Corangamite CMA will consult
with the Lower Barwon Community Advisory Committee
to determine the recommended watering regime for both wetlands from October 2020 to June 2021. Any future management of Reedy Lake and Hospital Swamps is expected to include a winter filling phase under all scenarios and so that watering action has been included in the table. This section of the seasonal watering plan will be formally varied before October 2020 to describe the potential watering actions that may be delivered for the rest of the 2020–21 water year. Variations to the seasonal watering plan will be published on the VEWH website (www.vewh.vic.gov.au) before the planned watering actions are delivered.

 Planning scenario
   Dry
   Average
   Wet
   Expected river conditions
 • Some natural inflows from the Barwon River in winter/ spring
• Dry conditions over summer will assist in the drying of the wetlands
 • Some natural inflows from the Barwon River in winter/ spring
• Conditions over summer may assist drying of the wetland water levels
 • Overbank flows are likely to wet the wetlands as a result of higher river flows, stormwater inflows and local rain/run-off
• Extensive drying of the wetlands is unlikely
 Reedy Lake
  • Winter/spring fill
  • Winter/spring fill
  • Winter/spring fill
 Hospital Swamps
   • Winter/spring fill
   • Winter/spring fill
   • Winter/spring fill
  1 The table only includes potential watering actions for July–September 2020. Potential watering actions for the rest of the year will be based on the independent review of the lower Barwon wetlands watering trial 2016–17 to 2019–20.
