WATER SHARING PLAN FOR THE ROCKY CREEK, COBBADAH, UPPER HORTON AND LOWER HORTON WATER SOURCE 2003 - REG 17

17 Flow classes

(1) For the Rocky Creek and Cobbadah management zones this Plan establishes the following flow classes:

(a) very low flow class at or less than 2 megalitre per day (hereafter "ML/day"),

Note: 2 ML/day is referred to as the cease to pump on a falling river and the commence to pump on a rising river in these management zones.

(b) A class flows greater than 2 ML/day and at or less than 3 ML/day,

(c) B class flows greater than 3 ML/day and at or less than 11 ML/day, and

(d) C class flows greater than 11 ML/day.

(2) For the Upper Horton management zone this Plan establishes the following flow classes:

(a) very low flow class at or less than 2 ML/day,

Note: 2 ML/day is referred to as the cease to pump on a falling river and the commence to pump on a rising river in the Upper Horton management zone.

(b) A class flows greater than 2 ML/day and at or less than 6 ML/day,

(c) B class flows greater than 6 ML/day and at or less than 21 ML/day, and

(d) C class flows greater than 21 ML/day.

(3) For the Lower Horton management zone this Plan establishes the following flow classes:

(a) very low flow class at or less than 4 ML/day,

Note: 4 ML/day is referred to as the cease to pump on a falling river and the commence to pump on a rising river in the Lower Horton management zone.

(b) A class flows greater than 4 ML/day and at or less than 18 ML/day,

(c) B class flows greater than 18 ML/day and at or less than 67 ML/day, and

(d) C class flows greater than 67 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.
