Highlights

Activities

Macroinvertebrate surveys found large numbers and types of mudflat invertebrates that had extended their distribution in the North Lagoon of the Coorong. Long-term recovery of invertebrates means better food availability for native fish and waterbirds. (Photo: S. Dittmann).

Community

The Living Murray Indigenous Partnerships Program Forum was held at the Coorong, Lower Lakes and Murray Mouth Icon Site. First Nations’ representatives from along the River Murray heard from the Traditional Owners (Ngarrindjeri), scientists and local community about the importance of flows connecting the river and the sea for the environment and its people.

Vegetation

Seasonal variation in Lower Lakes water levels has improved the growth of plants around the edges of the lakes, providing nesting places for birds and shelter for small native fish such as the southern pygmy perch. (Photo: S. Wedderburn)

Waterbirds

Watering of the Tolderol Game Reserve wetlands supported over 1,000 migratory shorebirds across 18 listed species, including the sharp-tailed sandpiper and red-kneed dotterel. (Photo: S. Dittmann)

Fish

High numbers of pouched (top) and short-headed (bottom) lampreys were recorded in winter moving through the barrages upstream to freshwater. Lamprey, like many other fish in this part of the system, rely on connectivity between fresh and saltwater to survive and breed. (Photo: T. Steggles)

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.
