For the purposes of the National Water Account 2010, all surface water entitlements in the Adelaide region are considered to be unregulated because water cannot be ordered by licence holders. Consequently, the surface water liability is not recognised in the water accounting statement.
There are surface water allocations for the Barossa Prescribed Water Resource Area and Little Para Prescribed Watercourse. Carryover of allocations is permitted in the Barossa, but not for the Little Para. Further information on these surface water entitlements is presented in the Water rights, entitlements, allocations and trade note.
