#13610 13 Mar 2020 Pending Notes:

Rain last 48 hrs = 0 mm; Atmos. pressure = 1011 hPa.

Rained continuously during monitoring period!

Heavy wind and wave surges pushed water across the berm opposite the BmP2 observation site. These inflows temporarily raised the estuary water level by up to 2 cm.  

#13574 15 Feb 2020 Pending Notes:

Rain past 48 hrs = 1.4 mm; Atm. Press. = 1012 hPa

Mouth opening continues to shift south.

#13544 24 Jan 2020 Pending Notes:

Rain past 48 hrs = 14.6 mm; Atm. Press = 1009 hPa.

River mouth has moved Southwards. Although no tidal influence was observed, dark water stains on the estuary bank indicated that there was tidal intrusion during the 1.8 m high tide of the previous night.

#13469 22 Dec 2019 Approved Notes:

No rain past 48 hrs; Atm press = 1024 hPa.

#13413 18 Nov 2019 Approved Notes:

Rainfall past 48 hrs = 0.8 mm; Atm. Press = 1015 hPa

Tidal influence would have been greater at 04:18 hrs when the predicted tide height was 2.03 m. 

#13372 21 Oct 2019 Pending Notes:

Rainfall past 48 hrs = 0.8 mm; Atm. press. = 1030 hPa.

River level observed to be slowly dropping after recent rains. 

#13312 13 Sep 2019 Approved Notes:

Rainfall past 48 hrs = 1.6 mm; Atm. press = 1023.5 hPa.

There is an ongoing build-up of sediment and debris at the river gauge. (See photo.)  River height readings may not be possible during dry months.  

Question for Estuarywatch co-ordinator: Vegetation growth has progressively obscured our vision of the river mouth from Photopoint BmP3. (See photo BmP3-3). Other viewpoints have advantages, and may deserve consideration. (See, for example, photo BmP2-5.)  

#13245 14 Aug 2019 Approved Notes:

1.8 mm rain past 48 hrs; atm. press. = 1027 hPa

#13187 8 Jul 2019 Approved Notes:

Rain past 48 hrs = 8 mm; Atm. pressure = 1024 hPa

School holidays: Visitors with dogs frequent estuary vicinity. 

#13120 10 Jun 2019 Pending Notes:

Rainfall past 48 hrs = 1 mm; Atm. press. = 1006.2 hPa

Estuary water level high, accompanied by considerable width.

Note the river levels observed at BmP2 were not steady, but showed short term fluctuations within the range 1.16 to 1.23 m, according to wave action at the river mouth.  

#12910 8 May 2019 Approved Notes:

19 mm rain during past 48 hrs; atmospheric pressure = 1019 hPa.

At GOR bridge observation point BmP2, a developing sand berm was observed spreading across the river towards the fishing platform. 

#12847 12 Apr 2019 Approved Notes:

Rain past 48 hrs = 0 mm;  Atm Press = 1024 hPa.

Holiday makers enjoying perfect weather.

#12779 21 Mar 2019 Approved Notes:

Rain past 48 hrs = 0.4 mm; Atm Press. = 1018.2 hPa

Solid berm across mouth, which has been closed for 10 days. 

River has flooded above its banks.

Recent rain in watershed today raised river height 3 cm from 12:15 to 15:00 hrs.

#12709 20 Feb 2019 Approved Notes:

No rain during past 48 hrs; Atmos pressure = 1014 hPa. 

At mouth, river has cut through sand berm deposits.

#12643 16 Jan 2019 Approved Notes:

0 mm rain during past 48 hrs; Atm press = 1010.1 hPa

River mouth characterized by meandering channel; rocks exposed where river enters ocean. 

#12589 12 Dec 2018 Approved Notes:

Rainfall past 48 hrs = 0;  Atmospheric pressure = 1007.5 hPA.

Wide build-up of sand at mouth narrows mouth and river passage. 

Observed decrease in water level between 14:00 & 17:15 is more likely due to drawdown of river after the mouth opening in the prior 24 hrs, rather than to tidal influence. No upstream influence was observed at high tide. 

Vegetation growth over the years on the bank below the BmP3 observation point is starting to obscure vision of the estuary on the inland side. (e.g., compare image BmP3-3 with past images from the same data point taken in Dec 2012.)

#12520 11 Nov 2018 Approved Notes:

Rain past 48 hrs = 0 mm;  Atm press = 1022 hPa

Narrow opening at mouth, with large exposed expanse of sand, even at high tide.  Rocks well-exposed on NE side of mouth. 

 

#12431 2 Oct 2018 Approved Notes:

Rainfall last 48 hours 0.0mm,  Air Pressure 1023.6 hPa

#12365 31 Aug 2018 Approved Notes:

Rainfall past 48 hrs = 0.2 mm; Atmos pressure = 997.7 hPa.

River mouth wide and relatively deep. 

Water level at gauge showed periodic fluctuations (within a range of 0.06 m), due to the surge and ebb of surf at the river mouth.

#12301 1 Aug 2018 Approved Notes:

Rainfall past 48 hrs = 10.8 mm

Atm pressure = 1017.8 hPa

Due to recent rains there is downriver flow, but this is opposed by the high tide, resulting in small net change of river height at the estuary during the time we were monitoring. 

#12237 4 Jul 2018 Approved Notes:

Rain past 48 hrs = 0; Atm pressure = 1014.6 hPa

 

#12111 4 Jun 2018 Approved Notes:

Rain past 48 hrs = 0.2 mm; Atm press = 1024 hPa

#12014 3 May 2018 Approved Notes:

Rain past 24 hrs = 0; Atm press = 1008.6 hPa

Car park at Barham bridge is now clear of roadworks materials.

Flock of about 100 terns on berm south of mouth.

 

#11904 20 Mar 2018 Approved Notes:

Rain past 48 hr = 2 mm; Atm. press = 1025.4 hPa

River level high - banks flooded at bridge. At low tide mouth would be closed, but at full tide (14:30) storm surge waves breach over the berm at the river mouth and move up the river. 

Terns and gulls sheltering on land-ward side of dune build-up at mouth. 

Photo note: BmP3_1 & _BmP3_2 are simple crops of BmP3_pan, made using garden-variety photo app.  

#11817 16 Feb 2018 Approved Notes:

Rain past 48 hrs = 4.5 mm; Atmos Pressure = 1013.7 hPa

As of 1/1/2018, car park has been cleared and graded with crushed rock.

Sand deposited at mouth has produced high water levels in estuary, with the small berm just washed over at high tide. At other times, the mouth is closed. 

Starting with the next sampling, photographs BmP3-1 and BmP3-2 will not be uploaded.  Panoramic photo BmP3-3 includes all information contained in BmP3-1 and BmP3-2, and moreover, is easier to interpret.
