River Murray irrigators in South Australia will get more water from next month with a decision by the state government to lift allocations from two to six per cent.
River Murray Minister Karlene Maywald said while 300 gigalitres of in-flows to the River Murray system were recorded during July, the majority flowed into tributaries in NSW and Victoria.
The improvement to the shared resources was estimated at just 35 gigalitres.
"Unfortunately, these in-flows to interstate tributaries are not part of the water resource available for sharing between all states," Ms Maywald said.
"At the moment we are just not seeing the rain falling in the areas that will contribute in-flows to the shared resource, which is what we need for South Australia to have access to more water."
Ms Maywald said the government would continue to update allocations to irrigators on the 15th of each month.
"Maximising the amount of water available to irrigators as early as possible in the season is essential to help producers plan their irrigation for the year," she said.
