sec.14 Performance indicators for environmental flow objectives
The performance indicators for the environmental flow objectives are— for assessing periods of low flow— 50% daily flow; and 90% daily flow; and daily flow less than 1ML; and number of periods of no flow of at least 1 month but less than 3 months; and number of periods of no flow of at least 3 months but less than 6 months; and number of periods of no flow of at least 6 months; and for assessing periods of medium to high flow— mean annual flow; and 1.5 year daily flow volume; and 5 year daily flow volume; and 20 year daily flow volume; and for assessing seasonal flow patterns— flow regime class; and annual proportional flow deviation.
