sch.7-sec.1 Mean annual flow

An environmental flow objective for surface water to which this plan applies is that the performance indicator mentioned in subsection (2) is not less than what the performance indicator was immediately before the commencement. The performance indicator, for nodes A, H and I, is the mean annual flow at each node as a percentage of the pre-development flow for the node. In this section— mean annual flow , at a node, means the total volume of flow of water at the node in the simulation period, divided by the number of years in the simulation period. pre-development flow , for a node, means the mean annual flow at the node simulated as if— there were no dams or other water infrastructure in the plan area; and no water had been taken under authorisations in the plan area.

• (a) there were no dams or other water infrastructure in the plan area; and
• (b) no water had been taken under authorisations in the plan area.
