Geography
The Piako River has an annual mean flow of 17 cubic metres per second (600 cu ft/s) (at Paeroa-Tahuna Road), with a total catchment area of approximately 1,440 square kilometres (560 mi2). The river system is approximately 100 kilometres (62 mi) long, aligned in a north–south direction and occupies much of the central and western Hauraki Plains (or more broadly, the Thames Valley), extending from Hinuera in the south before discharging into the Firth of Thames in the north, five kilometres west of Thames.
The Piako River has two major stems: the first, and main, stem drains the northern Te Miro-Tahuroa hills, and the Pakaroa Range. The dominant tributaries on the eastern slopes of these hills are the Piakonui and Piakoiti Streams.
