The performance indicators for the environmental flow objectives are—
(a) for assessing periods of low flow—(i) 50% daily flow; and(ii) 90% daily flow; and(iii) daily flow less than 1ML; and(iv) number of periods of no flow of at least 1 month but less than 3 months; and(v) number of periods of no flow of at least 3 months but less than 6 months; and(vi) number of periods of no flow of at least 6 months; and
(b) for assessing periods of medium to high flow—(i) mean annual flow; and(ii) 1.5 year daily flow volume; and(iii) 5 year daily flow volume; and(iv) 20 year daily flow volume; and
(c) for assessing seasonal flow patterns—(i) flow regime class; and(ii) annual proportional flow deviation.
