 5.2 Victorian Murray system
Table 5.2.14 Potential environmental watering actions and objectives for the Lindsay, Mulcra and Wallpolla islands
 Potential environmental watering action
  Functional watering objectives
  Environmental objectives
   Wallpolla Island
     Wallpolla Horseshoe Lagoon (partial or complete fill in spring/autumn)
     • Wet/drown river red gum saplings in the bed of Wallpolla Horseshoe to limit their coverage
• Provide suitable breeding conditions for waterbirds
• Provide shallow-water habitat and open-water habitat to create foraging and breeding opportunities for waterbirds, frogs and turtles
• Provide the conditions for lake bed herbaceous plants and semi-aquatic plants to grow in the littoral zone during the drying phase after watering
• Provide nursery habitat for naturally occurring fish populations and juvenile golden perch and silver perch stocked by Victorian Fisheries Authority to increase growth rates before fish are released to the Murray River
                 Finnigans Creek (low flow in spring)
 • Provide connections between Wallpolla East, Sandy Creek and Finnigans Creek to allow nutrient exchange, increased wetland productivity and the dispersal of plant propagules
• Provide variable water levels in the littoral zone to improve wetland productivity and promote the growth of native aquatic and fringing plants
• Provide variable water levels in the littoral zone to provide feeding habitat for shorebirds
• Provide open-water habitat to create foraging opportunities for waterbirds
        Sandy Creek (low flow in winter/spring)
 Wallpolla Creek East (low flow in winter/spring)
 1 The autumn fresh in the Lindsay River also has an operational objective of providing water that can be efficiently delivered to Lake Wallawalla via pumping.
