Wirn wirndook Yeerung (Macalister River)
Water for the environment delivery planned.
A water for the environment delivery is planned for Wirn wirndook Yeerung (Macalister River), with dams and storages typically capturing increased autumn and winter inflows from rainfall, the river downstream of the reservoir has lower flows than would naturally occur at this time of year.
A continuous low flow through to the end of June helps to maintain the depth and connection between instream pools, providing access to habitat for water bugs, fish and platypus.
The late autumn fresh provides another opportunity for the downstream migration of Australian grayling and contributes freshwater to the lower reaches of the Latrobe River and lower Latrobe wetlands.
