Highlights

Activities

Local school groups visited the floodplain to learn about ecology and culture. Following an Acknowledgement of Country from Mallee CMA’s Aboriginal Engagement and Water Officer, the groups learned about significant sites such as middens, scar trees and boundary trees. Students also collected data and worked with a scientist to learn about floodplain plants and animals. (Photo: Mallee CMA)

Community

The benefits of water for the environment to river red gums at Hattah-Kulkyne National Park were presented to a native tree forum in Mildura, with attendees hearing about the scientific methods used to measure healthy tree populations.. (Photo: Mallee Catchment Management Authority)

Vegetation

Following natural floods in 2012, consecutive years of water for the environment delivery has sustained trees and plants during dry and hot conditions. (Photo: Mallee CMA)

Waterbirds

Six regent parrots, a nationally listed species, were detected at Lake Lockie during the autumn bird survey. (Photo: Mallee CMA)

Fish

Surprisingly, Murray cod bred and survived to become juveniles in Lake Mournpall in 2019. Their presence suggests that the Hattah Lakes can support young large-bodied native fish. (Photo: Chris Bloink, Ecology Australia)

Each year, water is released into the environment depending on the climatic conditions. See the outcomes of water over time for a long-term view of how natural and released water affects the health of rivers.
