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. 

Rainfall last 48 hours 0.0mm,  Air Pressure 1023.6 hPa

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.

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. 

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

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

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.

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.  

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.

No rain previous 48 hrs; atm pressure = 1015 hPa.

Roadworks adjacent to monitoring point BpM2 have been completed and parking area restored.

Rainfall past 48 hrs < 1 mm; Atmospheric pressure = 1015 hPa.

Location and shape of mouth has altered considerably since last monitoring visit. 

Rain past 48 hrs = 0; Atm. press. = 1008.9 hPa.

Water level not readable on gauge due to mud bank deposits. Judged to be < 0.5 m. At finish of observations the level was still below 0.5 m, but was estimated to have risen by 1-2 cm.

Observed wetting of sandbanks near the photopoint, presumed to be due to the previous high tide, supports the existence of tidal influence.

Access to monitoring point BmP2 is considerably impeded by untended vegetation growth and by stockpiles for ongoing road construction. New season's growth also hinders access along the foot track leading to BmP3.

Rain during past 48 hrs = 0.4 mm; atm press = 1004.6 hPa

Car park at Barham bridge closed to traffic owing to use by roadwork plants and for storage of roadwork materials. Significant roadworks still in progress.

4.0 mm rain during past 48 hrs; Atm. press = 1026 hPa.

Carpark at bridge continues to be used as base for ongoing drain and roadworks. Rolls of coir matting have been laid around the area to restrict run-off into the estuary. (See pix.)

Due to heavy rain in catchment over the past week, river mouth is wide with consistent outflow.

Rainfall past 48 hrs = 1 mm; Atmospheric pressure = 1008.6 hPa

Heavy winds previous day; large ocean swells. 

Carpark at bridge observation point BmP2 is being intensively used for the storage of excavator plant machinery and gravel for ongoing drainage and sewage works. It appears that this work will continue for some months. See added photo attached.

Rain past 48 hrs = 11.6 mm; rain past week > 20 mm.

Air press. = 1029.4 hPa.

Rain during past week has raised river level above normal. Strong outward flow at mouth.

Rainfall past 48 hrs = 2.6 mm; Atmos. press - 1022.2 hPa.

High tide 11:45

Very still atmosphere. A stretch of mechanically-dumped sand was observed, placed to consolidate the beach of Mounts Bay in the vicinity of Marengo.

The condition of the car park at the bridge opposite the campground is in poor condition. Added to previous debris-dumps from the campground, there now exists a large mulch pile to further restrict parking and public access.

Rainfall past 48 hrs = 4.2 mm; Atmos. pressure = 1024.5 hPa.

Rain overnight has raised river level. Completely still atmosphere, overcast, grey, & smokey due to ongoing forestry controlled burn at Gellibrand.

Rainfall past 48 hr = 1.4 mm; Atmos. Press = 1009.5 hPa.

Otherwise closed, the mouth opens at peak high tides with small waves moving over the sand bar for a short distance upstream. No outward flow observed. Estuary is wide and relatively high due to the mouth closure when tide is not at peak.

Rainfall last 48 hours 0 mm;  Atmospheric Pressure 1012.1hPa.  River level higher than expected.  Open mouth was wide and shallow.  There would be an exposed sand bar at low tide.  New vegetation growth 30 metres upstream of river mouth.  Large flocks of gulls and terns resting on berm edge upstream of river mouth.

Rain last 48 hrs = 0 mm; atmos press = 1018 hPa.

Moderate high tide and smooth ocean so little wave action at mouth; wide strand on beach.

Estuary mouth narrow and shallow.

Water stain along river bank suggests tidal influence during previous (midnight) higher tide.

Rain past 48 hrs = 6.8 mm; Atm press = 1007.9 hPa

Following overnight rain, river height was observed to drop slightly during monitoring period.

Sand bank at bridge fishing platform is well established and vegetated with grass

Rainfall past 48 hrs = 2.4 mm

Atmos pressure = 1024.1 hPa

Sand has accumulated and spread horizontally, widening the berm at the open river mouth.

Rainfall past 48 hrs = 27.6 mm; atmos pressure = 100.6.6 hPa.

Rainfall past 48 hrs < 2 mm.  

Air pressure = 1017.8 hPa.

Large flock of terns on berm south of estuary mouth.
