The performance indicators for the environmental flow objectives are—
(a) for assessing periods of low flow—the base flow; and
(b) for assessing periods of medium to high flow, the following—(i) mean annual flow;(ii) median annual flow ratio;(iii) annual proportional flow deviation;(iv) mean wet season flow;(v) 4% daily exceedance duration flow;(vi) 10% daily exceedance duration flow;(vii) 2 year daily flow volume;(viii) 5 year daily flow volume;(ix) 20 year daily flow volume; and
(c) for assessing the first post-winter flow event—the performance indicators listed in schedule 6 , part 3 .
