WATER SHARING PLAN FOR THE JILLIBY JILLIBY CREEK WATER SOURCE 2003 - REG 17

17 Flow classes

This Plan establishes the following flow classes as the basis for sharing of daily flows:

(a) very low flow class at or less than:

(i) 0.5 megalitres per day (hereafter "ML/day") in year 1 of this Plan,

Note: The 0.5 ML/day in subclause (a) (i) corresponds to the estimated 94 th percentile of all days with flow, and is referred to as the cease to pump on a falling river and the commence to pump on a rising river.

(ii) 0.75 ML/day in year 2 of this Plan, and

Note: The 0.75 ML/day in subclause (a) (ii) corresponds to the estimated 92 nd percentile of all days with flow, and is referred to as the cease to pump on a falling river and the commence to pump on a rising river.

(iii) 1 ML/day from year 3 of this Plan,

Note: The 1 ML/day in subclause (a) (iii) corresponds to the estimated 90 th percentile of all days with flow, and is referred to as the cease to pump on a falling river and the commence to pump on a rising river.

Note: There is no A class in this water source.

(b) B class flows:

(i) greater than 0.5 ML/day and at or less than 3.3 ML/day in year 1 of this Plan,

(ii) greater than 0.75 ML/day and at or less than 3.3 ML/day in year 2 of this Plan, and

(iii) greater than 1.0 ML/day and at or less than 3.3 ML/day from year 3 of this Plan,

(c) C class flows greater than 3.3 ML/day and at or less than 8 ML/day, and

(d) D class flows greater than 8 ML/day.

Note: The flow classes have been determined based on flow information that inherently includes seasonal effects as well as evaporation and seepage losses.
