Lake Waiparera is the largest of the Aupouri Peninsula lakes (108 hectares) but is relatively shallow (5.2 m). The lake catchment is approximately 70% pasture (mostly fenced) with the remainder in native scrub or wetland. The lake has several inflows, mostly drains on the south western side, but also a drain on the north-western and north eastern shores. There are no obvious outflows (source lawa.co.nz).
