Lindsay, Mulcra, Wallpolla highlights 2016–17


A workshop with a group of Indigenous women discussed the range of animals and plants at Lindsay, Mulcra and Wallpolla Islands, and explored how water for the environment can benefit these, including snakes, lizards and possums.  


There was a diverse range of native fish across most of the site. Golden perch, freshwater catfish and bony herring were in higher abundance than previous years.


Wetlands contained more water than in the previous year, which provided great feeding and breeding habitat for waterbirds. Record numbers were recorded across the site. Lake Wallawalla, near Lindsay Island, was one of the most popular destinations for a range of waterbirds. 


River red gum are in the best condition since monitoring began in 2008.

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.

Current activities

Lindsay, Mulcra and Wallpolla Islands is currently planning the delivery of water for the environment as connectivity flows through Mullaroo Creek and Lindsay River in 2018/19. A partial fill of Lake Wallawalla will depend on water availability and weather conditions.

Good numbers and diversity of waterbirds were again observed at Lake Wallwalla in January 2018. 

Positive signs in response to the 2016 natural floods and high rainfall continue to be witnessed across the site. Black box and river red gum trees are producing new foliage and buds. Areas of lignum were also observed to have improved in condition, although there are still some areas that are showing signs of stress.
