WATER SHARING PLAN FOR THE KANGAROO RIVER 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:

(i) at or less than 2.96 megalitres per day (hereafter "ML/day") on a falling river and at or less than 4 ML/day on a rising river in the first year of this Plan,

(ii) at or less than 4 ML/day on a falling river and at or less than 5.4 ML/day on a rising river, in year 2 of this Plan, and

(iii) at or less than 5.4 ML/day on a falling river and at or less than 7 ML/day on a rising river in years 3 to 10 of this Plan.

Note: 2.96, 4 and 5.4 ML/day are referred to as the cease to pump on a falling river, and 4, 5.4, and 7 ML/day are referred to as the commence to pump on a rising river. The 7 ML/day corresponds to the estimated 95th percentile flows in the critical month.

Note: Provisions are established for access to the very low flows under clause 62.

(b) A class:

(i) flows greater than 2.96 ML/day and at or less than 30 ML/day on a falling river, and flows greater than 4 ML/day and at or less than 30 ML/day on a rising river in the first year of this Plan,

(ii) flows greater than 4 ML/day and at or less than 30 ML/day on a falling river, and flows greater than 5.4 ML/day and at or less than 30 ML/day on a rising river in year 2 of this Plan, and

(iii) flows greater than 5.4 ML/day and at or less than 30 ML/day on a falling river. and flows greater than 7 ML/day and at or less than 30 ML/day on a rising river in years 3 to 10 of this Plan.

(c) B class flows greater than 30 ML/day and at or less than 118 ML/day, and

(d) C class flows greater than 118 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.
