At any point on a watercourse in the plan area—
(a) the mean annual flow, expressed as a percentage of the mean annual flow for the pre-development flow pattern, be at least 70%; and
(b) the median annual flow, expressed as a percentage of the median annual flow for the pre-development flow pattern, be at least 60%.
At each node mentioned in column 1 of the table below—
(a) the mean annual flow, expressed as a percentage of the mean annual flow for the pre-development flow pattern, be at least the percentage stated for the node in the table, column 2; and
(b) the median annual flow, expressed as a percentage of the median annual flow for the pre-development flow pattern, be at least the percentage stated for the node in the table, column 3.
