Find out how water for the environment is planned and prioritised, how environmental outcomes are identified, and how we plan for future use of water for the environment.

In 2018, the Murray–Darling Basin Authority commissioned an independent review by eminent hydrology experts of the risks posed by reduced return flows. This was in response to concerns raised that increases in groundwater sustainable diversion limits and irrigation efficiency projects may lead to reductions in river flow and offset the benefits of surface water recovery for the environment.

Over recent years there have been significant changes in water use on the River Murray between Barmah and the South Australian border. This study investigates the changes historical data shows over time.
