Relatively high rainfall up on the mountain quickly drains through these river systems, contributing to high
water flows and the swift clearance of excessive sedimentation. This has resulted in, clean, clear water

g/m3 grams per cubic metre, and equivalent to milligrams per litre (mg/L). In
water, this is also equivalent to parts per million (ppm), but the same
does not apply to gaseous
estuaries such as the Tongaporutu, Waitara
and Pātea rivers, and the confines of Port Taranaki.
The Taranaki region has a temperate climate with
generally abundant rainfall. The incised nature of
ring plain streams means that flooding is not a
major problem. However, occasional intense rainfall
events can lead to rapid rises in river levels and
flooding in hill country valleys and elsewhere.
