Physical CharacteristicThe Waipaoa River rose to within 5 or 6 in (12.7-15.2 cm) of the banks at about 10am on the 30th.

Large quantities of silt brought down wiped out the navigable channel for shipping purposes, which had been recently dredged. From about 200 ft () inside the entrance, the silting extended for practically the whole length of the channel, reducing the depth to 4 ft (1.2 m).
