National Water Account 2018

Adelaide: Key findings

For the water account period 1 July 2017–30 June 2018

  • Despite high rainfall in July–August 2017, rainfall for the year was below average.
  • Relatively poor rainfall for most of the year resulted in the first annual decrease in surface water storage in three years.
  • The decrease in the region's surface water availability meant inter-region transfer from the River Murray increased from last year to meet urban demand.
