sch.6-sec.2 First post-winter flow event objectives

The first post-winter flow event objectives are— first post-winter flow events that pass through dams, weirs, barrages, watercourses or lakes are to mimic the pre-development flow pattern of first post-winter flow events in duration, timing and magnitude; and for each node mentioned in table 4, column 1— the performance indicator mentioned in item 1(a) is to be at least the percentage stated for the node in table 4, column 2; and the performance indicator mentioned in item 1(b) is to be at least the percentage stated for the node in table 4, column 3; and the performance indicator mentioned in item 1(c) is to be at least the percentage stated for the node in table 4, column 4; and the performance indicator mentioned in item 1(d) is to be at least the percentage stated for the node in table 4, column 5; and the performance indicator mentioned in item 1(e) is to be at least the percentage stated for the node in table 4, column 6; and the performance indicator mentioned in item 1(f) is to be at least the percentage stated for the node in table 4, column 7; and the performance indicator mentioned in item 1(g) is to be at least the percentage stated for the node in table 4, column 8.
