Functional watering objectives
• Maintain salinity within 25,000–60,000 EC (may go up to 80,000 EC) to support suitable habitat and breeding conditions for Murray hardyhead and growing conditions of submerged aquatic plants
• Maintain salinity within 25,000–60,000 EC (may go up to 80,000 EC) to support suitable habitat and breeding conditions for Murray hardyhead, and growing conditions of submerged aquatic plants
• Provide permanent water as habitat for waterbirds
• Promote growth and maintenance of submerged and emergent aquatic vegetation
• Provide feeding and breeding habitats for growling grass frog and other frog species
• Provide open water and foraging habitats for shallow wading waterbirds and mudflat specialists to feed and breed
• Provide refuge and recruitment sites for freshwater turtles
• Promote the growth and maintenance of existing red gum trees
• Provide feeding and breeding habitats for growling grass frog and other frog species
• Provide recruitment sites for freshwater turtles
• Provide resting, feeding and breeding habitat to support waterbirds
• Support the growth of recently established reed beds to create nesting habitat for Australasian bittern
• Maintain water level above 74.0m AHD (Australian Height Datum) to support critical habitat and breeding for the southern purple spotted gudgeon
• Promote the growth of planted and naturally recruited river red gums, native semi-aquatic and aquatic plants, which provide high-quality habitat for waterbirds to feed and breed
• Maintain feeding conditions for waterbirds if significant waterbird breeding occurs
• Promote the growth and establishment of wetland plant communities to provide high quality habitat for waterbirds, reptiles and frogs to feed and breed
• Maintain food for nesting waterbirds if significant breeding occurs
• Deliver carbon-rich water to Pyramid Creek to increase the productivity of riverine food webs
