This page provides information on the volume of water allocated or carried over in each of the regulated systems that is currently available for use or trade, including a graphical comparison with the previous two years.
Water which is not used remains in storage for use or trade later in the season or to be carried over into the next season (subject to the carryover rules).
In the Murray, Goulburn and Campaspe systems any water quarantined in spillable water accounts is not available for use until a declaration of low risk of spill is made for the season. More information on spillable water accounts may be found here.
In some systems carryover is not allowed and so unused water is written off at the end of the season. This is the case in the Ovens system in the north and in the southern systems.
