River Murray irrigators can now use 100 per cent of their entitlements, the state government has announced, ending four and a half months of restrictions.
An extra 40 gigalitres of water became available to South Australia during the past fortnight, enabling the increase from a 94pc water allocation.
However, Environment and Water Minister David Speirs recommended water users begin planning for what would be a dry year ahead.
"Ongoing dry conditions across the (Murray-Darling) basin could have an impact on future water resource availability," he said.
In April, the government will announce the minimum allocation to be expected at the start of the next water year, on July 1.
Storages across the basin are at 41pc capacity, or about half the long-term average for this time of year.
