WATER SHARING PLAN FOR THE GWYDIR REGULATED RIVER WATER SOURCE 2002 - REG 30

30 Volume of the long-term extraction limit

(1) This Plan establishes a long-term extraction limit for this water source being the lesser of:

(a) the long-term average annual extraction from this water source that would occur with the water storages and water use development that existed in 1999/2000, the share components existing at the commencement of this Plan and application of a limit on supplementary water access licence extractions of 1 megalitre per unit share and the other water management rules defined in this Plan, or

(b) the long-term average annual extraction from this water source that would occur under Cap baseline conditions.

Note: An assessment of the long-term average annual extraction that would occur under the conditions specified in subclause (1) (a) has been made using the Gwydir IQQM computer model with system file WSP8TST6.SQQ. This indicates a long-term average annual extraction volume of 392,000 megalitres.

Note: An assessment of the long-term average annual extractions resulting from the baseline conditions in subclause (1) (b) has been made using the Gwydir IQQM computer model with system file dv93465a.s6_IQQMV6.61.001. This indicates a long-term average annual extraction volume of 415,000 megalitres.

Note: The long-term extraction limit recognises the effect of climatic variability on the availability of water, in accordance with section 20 (2) (c) of the Act as historic climate and river flow information is used in its determination.

(2) The values referred to in subclauses (1) (a) and (1) (b) shall be adjusted for any access licence dealing under section 71R of the Act.

(3) For the purposes of establishing the long-term extraction limit and auditing compliance with it, the following shall be included:

(a) all water extractions by all categories of access licences in accordance with the rules used for accounting of Cap diversions for Schedule F of the Murray Darling Basin Agreement,

(b) domestic and stock and native title rights extractions,

(c) volumes of water delivered as adaptive environmental water,

(d) floodplain harvesting extractions estimated to be taken for use in conjunction with extractions authorised from this water source, and

(e) water allocations assigned from access licence water allocation accounts in this water source to access licence water allocation accounts in another water source.

(4) For the purposes of establishing the long-term extraction limit and auditing compliance with it:

(a) the assessed volume of extractions shall be reduced by the volume of water allocations being assigned from the water allocation accounts of access licences in any other water source to the water allocation accounts of access licences in this water source, and

(b) the following shall not be included:

(i) replenishment flows made in accordance with this Plan, or

(ii) diversion of water pursuant to the planned environmental water rules in Part 3 of this Plan.
