SCHEDULE 4 – Environmental flow objectives

Part 1 - Low flow objectives

1 At each node mentioned in table 1, column 1—
(a) the percentage of the total number of days in the simulation period that the 50% non-zero daily flow is equalled or exceeded be at least the percentage stated, for the node, in table 1, column 2; and
(b) the percentage of the total number of days in the simulation period that the 80% non-zero daily flow is equalled or exceeded be at least the percentage stated, for the node, in table 1, column 3; and
(c) the percentage of the total number of days in the simulation period that the 90% non-zero daily flow is equalled or exceeded be at least the percentage stated, for the node, in table 1, column 4; and
(d) the percentage of the total number of days in the simulation period that the daily flow volume is zero be not more than the percentage stated, for the node, in table 1, column 5.
