New South Wales is currently reducing groundwater entitlements in over allocated aquifer systems such that total entitlements are more closely aligned with sustainable yields. This however will still not address the problem of local over abstraction where 'clusters' of bores exist which can be further compounded by relatively poor aquifer hydraulics at thoselocations. This situation can lead to groundwater levels falling to unacceptable depths. To address with this problem, the New South Wales government has developed a process to limit abstractions in these locally affected areas such that groundwater levels are brought back todesirable depths. Custom designed software has been developed to aid this process and help quantify the extent to which local extraction should be limited and also to define the timeframe over which the restrictions should be inforced such that water level objectives can bereached.
