The Murray Darling Basin Plan is Commonwealth Government legislation which came into effect on 22 November 2012.
It sets enforceable annual limits on the quantities of surface water and groundwater that can be taken from the Basin water resources.
The Basin Plan includes an Environmental Watering Plan that aims to protect and restore the environmental assets of the Basin, and a Water Quality and Salinity Management Plan that will establish water quality parameters for managing Basin water resources.
Water resource plans set out how water will be managed and generally correspond with existing Basin state water management areas.
More information about the plan, its rollout and subsequent amendments is available from the Murray Darling Basin Authority website.
