(3) However, the authorisation to take water under subsection (2) in a water year ends when the combined volume of water taken by the water allocation holder since the start of the water year equals the nominal volume for the water allocation.
(4) In this section—

"combined volume of water taken" , for a water allocation holder, means the total of—
(a) the volume of water taken by the water allocation holder under subsection (2) ; and
(b) the volume of water taken by the water allocation holder under section 53 that relates to the volume of water calculated under section 53 (3) (a) (i) .

53 Supplying and taking water under a water allocation

(1) The ROL holder may supply under a high priority water allocation in a relevant subscheme, and the water allocation holder may take, in a water year, the nominal volume for the water allocation.
(2) The ROL holder may supply under a medium priority water allocation in a relevant subscheme, and the water allocation holder may take, in a water year, the volume of water calculated under subsection (3) .
(3) The volume of water is calculated by—
(a) if—
(i) subsection (5) does not apply—multiplying the nominal volume for the water allocation by the announced allocation percentage for the medium priority water allocations in the relevant subscheme to which the water allocation belongs; or
(ii) subsection (5) applies—calculating the volume of water under subsection (5) ; and
(b) adding the volume of water, if any, that the water allocation holder carried over to the current water year under section 49 ; and
(c) adding the volume of water, if any, that the water allocation holder brought forward to the current water year under section 50 ; and
(d) subtracting the volume of water, if any, that the water allocation holder brought forward in the previous water year under section 50 .
(4) Subsection (5) applies if, during the water year, the water allocation holder—
(a) takes a volume of water under section 52 (2) ; and
(b) the volume of water mentioned in paragraph (a) is more than the difference between—
(i) the nominal volume for the water allocation; and
(ii) the volume of water calculated under subsection (3) (a) (i) .
(5) The volume of water for subsection (3) (a) (ii) is the volume calculated using the following formula—
where—

"NV" means the nominal volume for the water allocation.

"CWSV" means the volume of water that the water allocation holder takes under section 52 (2) during the water year.

Subdivision 2 - John Goleby subscheme

54 Application of sdiv 2

This subdivision applies to the John Goleby subscheme.

55 Definitions for sdiv 2

In this subdivision—

"first water period" , for a water year, means the period in the water year starting at the start of the water year and ending on the earlier of the following—

(a) if John Goleby Weir is overflowing at the start of the water year—
(i) when the weir stops overflowing;
(ii) 4 months after the start of the water year;
(b) if John Goleby Weir is not overflowing at the start of the water year—
(i) when the weir overflows;
(ii) the end of the water year.

"last water period" , for a water year, means the water period in the water year that ends on the end of the water year.

"subsequent water period" , for a water year, means each period in the water year starting at the end of a water period and ending on the earlier of the following—
(a) if John Goleby Weir is overflowing at the start of the period—
(i) when the weir stops overflowing;
(ii) 4 months after the start of the period;
(iii) the end of the water year;
(b) if the John Goleby Weir is not overflowing at the start of the period—
(i) when the weir overflows;
(ii) the end of the water year.

"water period" , for a water year, means—
(a) the first water period in the water year; or
(b) a subsequent water period in the water year.

56 Announced allocation percentage—initial percentage

(1) The ROL holder must, within 5 business days after the start of a water year, calculate a provisional allocation percentage for the John Goleby MP water allocations under section 59 .
(2) The announced allocation percentage for the John Goleby MP water allocations is the provisional allocation percentage calculated under section 59 .
(3) However, if the provisional allocation percentage calculated under section 59 is less than zero, the announced allocation percentage for the John Goleby MP water allocations is zero.
(4) The announced allocation percentage—
(a) takes effect on the first day of the water year; and
(b) subject to section 57 , has effect as the announced allocation percentage for the John Goleby MP water allocations for the first water period in the water year.

57 Announced allocation percentage—further calculations

(1) During the first water period in the water year, the ROL holder must calculate a provisional allocation percentage for the John Goleby MP water allocations under section 59
(a) within 5 business days after the start of each quarter of the water year, other than the first quarter; and
(b) within 10 business days after a major inflow for the John Goleby subscheme, other than a major inflow that causes John Goleby Weir to overflow.
(2) Also, the ROL holder may, at any time during the first water period in the water year, calculate a provisional allocation percentage for the John Goleby MP water allocations under section 59 .
(3) If the provisional allocation percentage calculated as mentioned in subsection (1) or (2) is greater than the announced allocation percentage currently in effect for the John Goleby MP water allocations, the provisional allocation percentage—
(a) takes effect as the announced allocation percentage for the John Goleby MP water allocations on the day on which the calculation is made; and
(b) has effect as the announced allocation percentage for the John Goleby MP water allocations for the first water period in the water year unless a greater announced allocation percentage takes effect under this section.

58 Publication of announced allocation percentage and start of subsequent water period

(1) The ROL holder must, within the required time after an announced allocation percentage takes effect for the John Goleby MP water allocations under section 56 or 57 , publish details of the announced allocation percentage for the water allocations on the ROL holder’s website.
(2) Also, the ROL holder must, within 5 business days after the start of a subsequent water period in a water year, publish details of the date on which the subsequent water period started on the ROL holder’s website.
Note—
Section 61 (4) states the volume of water that may be taken in a subsequent water period by the holder of a John Goleby MP water allocation.
Editor’s note for subsections (1) and (2)—
Details for the water supply scheme are on the ROL holder’s website.
(3) In this section—

"required time" means—
(a) for an announced allocation percentage that takes effect under section 56 —5 business days; or
(b) for an announced allocation percentage that takes effect under section 57 —2 business days.

59 Calculating provisional allocation percentage for John Goleby MP water allocations—ss 56 and 57

The provisional allocation percentage for the John Goleby MP water allocations is the lesser of the percentage calculated using the following formula, rounded up to the nearest whole per cent, and 100%—

where—

"UV" means the usable volume for John Goleby Weir.

"DIV" means the total volume of water taken under the John Goleby MP water allocations in the first water period in the water year in which the provisional allocation percentage is calculated.

"VIWY" means the total volume of water carried over to the current water year under section 60 by holders of John Goleby MP water allocations.

"MPA" means the total of the nominal volumes for the John Goleby MP water allocations.

60 Carry over

The ROL holder may allow the holder of a John Goleby MP water allocation to carry over unused water from the last water period in a water year to the first water period in the next water year.

61 Supplying and taking water under a John Goleby MP water allocation

(1) This section applies to the supply and taking of water in a water year under a John Goleby MP water allocation.
(2) In the first water period in the water year, the ROL holder may supply, and the holder of the water allocation may take, the volume of water calculated under subsection (3) .
(3) The volume of water is calculated by—
(a) multiplying the nominal volume for the water allocation by the announced allocation percentage for the John Goleby MP water allocations; and
(b) adding the volume of water, if any, that the water allocation holder carried over to the current water year under section 60 .
(4) In a subsequent water period in the water year, the ROL holder may supply, and the holder of the water allocation may take, the nominal volume for the water allocation.
(5) However, the total volume of water supplied or taken under the water allocation in the water year must not exceed 2.5 times the nominal volume for the water allocation.
