sch.7-sec.3 Days between fish migration flow events

An environmental flow objective for surface water to which this plan applies is that the performance indicator mentioned in subsection (2) is not more than what the performance indicator was immediately before the commencement. The performance indicator, for nodes A to L, is the total number of days in all intervening periods for each node as a percentage of the total number of days in the simulation period. In this section— fish migration flow event , for a node, means a continuous period of 1 or more days, between 1 September of a year and 31 May of the next year— starting when the daily water flow at the node is more than the fish movement threshold stated for the node in the following table; and ending when the daily water flow at the node is less than the fish movement threshold stated for the node in the following table. intervening period , for a node, means a period between fish migration flow events for the node that is— greater than the number of years stated for the node in the following table; and during the simulation period.
