Notes

Observation taken on the high tide. Ocean waves were washing into the estuary and causing the water in the lower part of the estuary to rise and fall by about 20 cm at the gauge board. The Powlett river was extemely high over the weekend of 23rd and 24th of June and also earlier in the month. High rainfall on the 21st and 22nd of June was responsible for closing many of the local roads and highways. Much debris has been deposited by the ocean waves inside the estuary on the eastern bank.
Very cold morning. NW wind Brrrrrrrrrrrrrrrrrrrr
