The Barwon Darling is an unregulated river system and extraction from year
to year is highly variable it depends on rainfall and river flows (not storage
releases).
High extractions correspond with high flow events, particularly when on farm
storages can be used to temporarily store water. Below are the annual usage
figures from the Barwon Darling river system from 1993⁄94 to
2016⁄17.
To put this into context, it is worth noting that, although some years have
very low or no flow, the average annual flow at Wilcannia (near the bottom of
the unregulated system and effectively the inflow to the Menindee system),
measured for over 100 years, is greater than 1,730,000 megalitres per year,
meaning more than a full Menindee system every year on average.
