Supporting information

The surface water liability decrease on banked environmental water managed by the Sydney Catchment Authority in the Sydney region is 0 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 0 ML.

As the banked environmental water entitlement has been deleted during the 2011–12 year, the total surface water  liability is zero (21.6 Other surface water liability increases and 5.6 Other surface water liability), the diversion is zero and therefore the forfeiture is zero.
