13.6 Other surface water liability decreases

Supporting information

The surface water liability decrease on banked environmental water managed by the Sydney Catchment Authority in the Sydney region is 5,363 ML.

As releases of banked environmental water ceased from 1 July 2011 and the water accounted as remaining in the bank was deleted during the 2011–12 year, the adjustment and forfeiture on the surface water liability is equal to the water that remained in the bank.
