Connectivity along waterways and support for native vegetation, native fish, frogs and other animals were the focus of the pattern of releases for the Snowy and Upper Murrumbidgee rivers in 2021–22.
Under a wet scenario, environmental water managers worked with partner agencies and stakeholders to coordinate the delivery of water for the environment to:
- provide variable flows to the Snowy and Upper Murrumbidgee rivers, with higher releases during winter and spring typical of snowmelt rivers
- improve the condition of the Snowy River channel and provide suitable habitat for water-dependent animals such as macroinvertebrates and native fish
- provide habitat diversity, suitable habitats and increase resource availability and productivity for water-dependent animals including macroinvertebrates, frogs, platypus, turtles and fish, as well as provide opportunities for breeding and recruitment
- inundate wetlands and ponds to provide breeding opportunities for several native frog species including the whistling tree frog (Litoria verreauxii)
- facilitate connectitivity along multiple rivers including the Snowy, Upper Murrumbidgee and Goodradigbee rivers.
