|16-04-2018 Estuary Entrance Opening
31/03/2018 at 16.00 the Barham river mouth has closed. The sea is smooth. The estuary height is 0.9m.
02/04/2018 at 17.40 the Paradise River Gauge is at 0.168m [fairly low]. The estuary height is 1.18m and the sea is smooth. The berm clearance is 0.23m.
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.
14/04/2018 at 10.00 the estuary height is 1.58m. Seas are slight but there is a strong West wind.
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.
16/04/2018 at 07.30 the estuary height is 1.7m, sea conditions are moderate to rough.The river mouth looks as if it has had an early morning natural opening. From fine debris lines it seems to have reached a peak estuary water height of 2.1m before the RM opening. The Paradise river gauge is at 0.32m. At 12.30 the estuary height is 1.2m.
|23-03-2018 Estuary Entrance Opening
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.
22/03/12018 at 08.15 the estuary height is 1.64 and the berm clearance is just under 0.2m. At 1.6m the estuary water starts to spread out into the backwater.
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.
|22-02-2018 Estuary Entrance Opening
15/02/2018 at 11.00 the River Mouth is closed and the estuary height is 1.09m. There is and has been strong West winds, and rough seas that were the main causal factor of the river mouth closure.
By the 19th the estuary height is 1.42m.
22/02/2018 at 11.15 the estuary height is 1.535m. The river mouth has just been opened illegally by a member of the Public. I estimate that a natural opening would occur at 1.7m or below.
23/02/2018 at 09.15 the estuary height is 1.01m.
|27-01-2018 Estuary Entrance Opening
24/01/18 at 09.00 the river mouth is closed. It is calm with light winds but I am sure there was moderate seas during the night. The estuary height is only 0.88m. The Paradise river flow gauge is at 0.165.
On Friday the 26th the estuary height is 1.1m.
27/01/2018 at 09.00 the river mouth has naturally opened and the estuary height is 0.92. This is the first multiple day river mouth closure of the season.
|28-05-2017 Water level
28/05/2017 at 13.39 the predicted high tide is 1.32mAHD. At 13.40 at the harbour the tide reading is 1.49mAHD [2.43mCD]. There is fresh NWW winds and the barometer is 1006.3. A large swell with the high tide is backing up and filling the estuary. At 13.45 the estuary height is 1.44mAHD.
