WATER PLAN (BURNETT BASIN) 2014 - SCHEDULE 7

SCHEDULE 7 – Environmental flow objectives

Part 1 - Surface water objectives

1 At each node mentioned in table 1, column 1, the number of periods of no flow of at least 6 months in the IQQM simulation period is to be no more than the number stated for the node in table 1, column 2.

2 At each node mentioned in table 2, column 1—
(a) the mean annual flow in the IQQM simulation period, expressed as a percentage of the mean annual flow for the pre-development flow pattern, is to be at least the percentage stated for the node in table 2, column 2; and
(b) the median annual flow in the IQQM simulation period, expressed as a percentage of the median annual flow for the pre-development flow pattern, is to be at least the percentage stated for the node in table 2, column 3.
