04/05/2018 at 8.30 the river mouth is just closed with the berm clearance zero. The estuary height has peaked at 1.21m. Seas are smooth.

This is the last river mouth closure for the season. There was a total of 5 river mouth closures for the season.

07/04/2018 at 09.30 the estuary height is 1.42m. An artificial opening of the river mouth has failed; closed by the following high tide. The berm clearance is below 0.3m.

12/04/2018 at 10.00 the estuary height is 1.53m, there is a moderate sea and moderate west wind. The berm has not been topped by waves since 07/04/2018.

15/04/2018 at 11.15 the estuary height is 1.92m. Gales and the rough seas  are crossing the berm in all areas without established vegetation.

15/04/2018 at 15.40 the estuary height is 1.98m and the berm clearance is 0.1m. Weather conditions are calmer. The Paradise river gauge after rain is at 0.37m but with little sediment in the water.

04/03/2018 at 18.00 the River mouth is closed, the sea is smooth and the estuary water height is 1.04m. The river flow is very low, below 0.15 at the Paradise river gauge. The high tide and low river flow appear to be the main contributors to the river mouth closure.

13/03/2018 at 11.30 the estuary water height has reached 1.26m.

The 19th, 20th and  21st of March seas are rough.

23/03/2018 at 09.00 the estuary height is 1.642m. The overnight high tide had covered an approved attempt at an artificial opening. The berm clearance is 0.23m.

23/03/2018 at 10.00 An approved artificial opening is being dug out again to protect a couple of camp sites which were not needed or used on the weekend.

23/03/2018 at 03.15 the river mouth is open and the estuary height is 1.32m.The artificial river mouth openings are being approved at lower and lower estuary water heights.
