Highlights

Activities

Water delivery via irrigation drip systems was trialled on a small area of black box. Trees and understorey plants responded positively, with this management option now being considered for other areas across Chowilla where black box is mostly in poor and declining condition (Photo: SA DEW)

Community

Traditional Owners at Chowilla worked with South Australian agency staff to implement Aboriginal Waterways Assessments which lead to the delivery of additional water for the environment support the successful completion of the kungardi (black swan) breeding cycle at Coombool Swamp. (Photo: SA DEW)

Vegetation

Reeds, rushes and other wetland plants flourished in response to water delivery at Lake Littra, providing habitat for bugs, fish and birds in an otherwise dry landscape. (Photo: SA DEW)

Waterbirds

An estimated 2,000 birds from 20 different species were observed at Coombool Swamp. This included migratory wading species such as sharp-tailed sandpipers, red-necked stints and the black-tailed godwit (rated rare in South Australia). Coombool also attracted seasonal species such as banded lapwings, a swamp harrier and Australian hobby. (Photo: SA DEW)

Fish

The number of Murray cod in 2020 was greater than all the previous years of sampling – mainly due to the high numbers of young-of-year (considered less than a year old) fish which was the highest in the 15 years of monitoring. (Photo: SA DEW)

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.
