Notes:
Rainfall in last 48 hours 7.8 mm Atmospheric Pressure 1000.0 hPa. |
|
#10333 | 25 May 2016 | Approved |
Notes:
Rain in last 48 hours 8.6 mm Atmospheric Pressure 1009.6 hPa Since last months monitoring high sea swells+ high tides + low Pressure produced several days of wave surge that appears to have moved much sand across the first berm and depositing it into the river. |
|
#10257 | 20 Apr 2016 | Approved | Notes: Rainfall lst 48 hrs 0mm, Atmospheric Pressure 1020hPaWater level at rain gauge is high with fishing platforms under water. Wide berm across closed mouth has caused the river to widen considerably,flooding hood plover nesting area. Berm length was 38metres. | |
#10196 | 11 Mar 2016 | Approved |
Notes:
Rainfall last 48 hours 7.2 mm. Atmos. Press. 1018.3 hPa Photo included of brush pile @fishing platforms car park - it continues to grow!!. Berm opposite fishing platform is quite high with colonizing vegetation well established. No evidence of wash over by waves. The Algae mat noted last month is now senescing. The river moouth opening, though wide, is shallow inhibiting water flow either in or out. Mouth would be CLOSED at low tide. We have enclosed a copy of a letter addressed to Otway Coast Committee regarding the brush dumping at the car park, for your information. |
|
#10076 | 15 Jan 2016 | Approved | Notes: Rainfall last 48 hours 4.2mm. Atmospheric Prressure 1032.5 hPa. Water stain on sandbank sugests the river level rose with the higher tide of 1.67 @04.06am, with rough waves surmounting the the berm at the mouth. Berm along the beach front is spotted with pioneering plants, and has been fenced off for hooded plovers nesting. Berm length 65.5m. | |
#10010 | 15 Dec 2015 | Approved |
Notes:
Rainfall last 48 hours 0mm, Atmospheric Pressure 1016 hPa Vegetation has established along the berm opposite the fishing platform and towards the mouth Water stain on river banks at the mouth suggests river level has been higher during the last 24 hours, suggesting the river level has been higher, possibly due to wave intrusion at high tide (1.66m ) at 03:05 |
|
#9954 | 21 Nov 2015 | Approved | Notes: Rainfall last 48 hrs 4.8 mm. Atmospheric Pressure 1022 hPa | |
#9839 | 13 Sep 2015 | Approved |
Notes:
Rainfall last 48 hours 0mm; Air Pressure 1022.5hPa A modest high tide and low rainfall resulted in low river level. Dunes well established. |
|
#9791 | 18 Aug 2015 | Approved |
Notes:
Rainfall last 24 hours 12.6 mm, Atmospheric Pressure 1023.1. There is a large build up of sand opposite the fishing platform at BmP2. Mouth opening is wide, with tidal waves traveling upstream for approx. 100 m. Monitors were absent from the region on holiday, so that the Mode information is lacking |
|
#9740 | 15 Jul 2015 | Approved |
Notes:
Rainfall last 48 hours 20.8 Atmospheric Pressure 1018 hPa High rainfall caused strong outward flow of river at mouth |
|
#9666 | 15 Jun 2015 | Approved | Notes: Rainfall lat 48 hours 0mm, Atmospheric Pressure 1025.3 hPa, Tidal inflow extended about 30 metres upstream. Noticeable sand deposition on foredune along beach front. | |
#9591 | 6 May 2015 | Approved | Notes: Rainfall last 48 hours 38 mm. Atmospheric Pressure 1008.3 hPa. Storm surge, high tide and high rainfall all contributed to exceptional water levels, overwashed berms and dramatic scenery. It is possible that at low tide the mouth would be closed - the water depth across the mouth was quite shallow at high tide. | |
#9528 | 7 Apr 2015 | Approved | Notes: Rainfall last 48 hours 1.4mm. Air pressure 1013.5Kpa. Very stormy weather. | |
#9433 | 3 Mar 2015 | Approved | Notes: Atmospheric Pressure 1017.3, rainfall last 48 hours 0 mm. River level is above banks, minor flooding in the riparian zone. Mouth berm is narrow, and a bigger high tide would wash over the berm blocking the river. There is a broad pondage of river water behind the berm. Tidal influence is questionable. The river level dropped marginally, probably due to river seepage underneath the berm. Berm length is 14 meters long. | |
#9359 | 2 Feb 2015 | Approved | Notes: 0.6 mm rain during past 48 hrs. Atmospheric pressure = 1020.4 hPa. Mouth closed! River just flooding over banks into campground oval. | |
#9288 | 4 Jan 2015 | Approved |
Notes:
Rainfall last 48 hours 6.00 mm. Atmosppheric Presssure 1018.1 hPa Mouth open with water flowing out through narrow winding channel. |
|
#9226 | 25 Nov 2014 | Approved |
Notes:
Rainfall last 48 hrs 8 mm. Atmospheric Pressure 1017.4 hPa. While there was no tidal influence at the time of monitoring, the high tide at 2 am did raise the river height considerably, leaving a tide water mark on river bank. Berm at the river mouth has been greatly reduced resulting in a flat beach. The River channel has been pushed against the mainland river bank. The flow through the mouth is shallow with a HT of 1.4m The shrubs previously obscuring the view of the river gauge have been trimmed back and gauges are now clear for reading. |
|
#9178 | 29 Oct 2014 | Approved |
Notes:
Rainfall last 48 hours 12 mm Considerable sand deposiition near mouth of the river. River level relatively high, causing good outward flow. Shrub growth around the river gauge is obsscuring view of readings. We will take branch cutting tools next month. |
|
#9148 | 1 Oct 2014 | Approved |
Notes:
Rainfall lst 48 hours 22 mm 24 hours previously gale force winds and heavy rain Currently weather much modified, sea relatively moderate, but breakers have steep fronts. Mouth outlet open but SHALLOW. Hooded plovers now on beach. |
|
#9094 | 2 Sep 2014 | Approved |
Notes:
Rainfall last 48 hours 8 mm Atmospheric Pressure 1019.8 hPa |
|
#9033 | 30 Jul 2014 | Approved | Notes: Rainfall during past 48 hrs was 23 mm in Otways. Atmospheric pressure = 1008.8 hPa. High-tide storm surge combined with recent rain produce elevated water levels in estuary. Berm breached in several places adjacent to river mouth. | |
#8990 | 5 Jul 2014 | Approved |
Notes:
Rain in last 48 hours 13mm Atmospheric Pressure 1009 hPa. Stormy weather during sampling with breakers causing storm surge up the river mouth, while rainfall provided good downstream flow at the same time. |
|
#8916 | 5 Jun 2014 | Approved | Notes: 5.6 mm rain in past 48 hr; atmospheric pressure = 1020.4 hPa | |
#8852 | 7 May 2014 | Approved | Notes: In the 48 hrs before these observation, 1.2 mm of rain was received. Atmospheric pressure = 1029.3 hPa. Rain (43mm) during previous week has raised water level in river; level now dropping. | |
#8813 | 3 Apr 2014 | Approved |
Notes:
Air pressure 1020.6 hPa; 0.4 mm rain previous 48 hr. At high tide waves overwash berm and push a storm surge upstream. At low tide there would be no surface flow. |
|
#8772 | 7 Mar 2014 | Approved |
Notes:
Rain fall last 48 hours Air Pressure 1022.5 hPa |
|
#8703 | 1 Feb 2014 | Approved |
Notes:
Rainfall last 48 hrs 0 mm, Atmospheric Pressure 1014 hPa January has been very dry, and has had a number of very hot days. Mouth opening is very narrow. At low tide the river flow would be blocked. |
|
#8649 | 2 Jan 2014 | Approved |
Notes:
2.6 mm of rain in past 48 hr. Air pressure = 1008.8 hPa. Water levels given above are estimates only because silt deposits conceal gauge readings less than the 0.6 m mark. Tidal influence was inferred from water water stain on bank above the current water level. |
|
#8609 | 2 Dec 2013 | Approved |
Notes:
Air Pressure 1016 hPa, Rainfall last 48 hours 0.00 m The river gauge was silted up to the 0.6 m mark, and Water Level entries are estimates only. Tidal influence was noted from the water stains left on the sand banks from an overnight high tide at 22:57 pm with a reading of 1.4m |
|
#8545 | 2 Nov 2013 | Approved |
Notes:
No rain last 48 hrs; Atmospheric pressure = 1015.5 hPa *** Water levels are estimates only as at these low levels the river gauge is obscured by mud deposition. |
|
#8511 | 4 Oct 2013 | Approved |
Notes:
Air pressure = 1021.0 hPa; 11.4 mm rain during past 48 hrs recorded at Cape Otway. Heavy rains and gale winds characterize preceding week. |
|
#8476 | 8 Sep 2013 | Approved | Notes: Air pressure 1027 hPa. | |
#8451 | 14 Aug 2013 | Approved |
Notes:
Rainfall last 48 hours 31 mm, Air Pressure 999.2 hPa River level is high due to heavy rainfall in preceding week, and to the high tide hindering outward flow. Berm at river mouth has been been eroded to lower its height. Mouth opening has widened. |
|
#8319 | 6 Jun 2013 | Approved |
Notes:
Rainfall last 48 hours 2.8 Air Pressure 1012.9 hPa Waves moving upstream at mouth of river |
|
#8257 | 1 May 2013 | Approved |
Notes:
Rainfall last 48 hrs 11 mm. Air Pressure 1021.3 hPa The river level is above the banks, flooding the camp ground, and the horse paddock as well as rest of flood plain near the river edge. Additional rainfall will intensify flooding. The berm opposite the fishing platform at the bridge has risen in height. At the Golf Course observation post the high tide breakers did travel over the closed mouth, but there is no outward flow of river water . Berm across the mouth at high tide is shallow, but wide 35 meters on river side and 7 metres on seaward side. |
|
#8199 | 28 Mar 2013 | Approved | Notes: Air Pressure 1013.9 hPa, Rainfall last 48 hrs 2.6 mm. Stormy conditions at time of sampling. River above banks and spreading to flats. Waves breaking over berms which have been reduced in height since last monitoring. At high tide waves were breaking over the shallow berm across mouth which would block outward flow at low tide. See photos. | |
#8125 | 28 Feb 2013 | Approved |
Notes:
Air Pressure 1017.3 hPa, Rainfall last 48 hrs 14.0mm Water Level in the river high with flooded fishing platforms, and full banks. Level is due to the sand bar which is just underwater at high tide at estuary mouth. Mouth would be closed at low tide. See additional photo for BmP3 showing mouth. The location of the mouth has shifted north since last monitoring. Berm has been greatly reduced in height |
|
#8048 | 31 Jan 2013 | Approved | Notes: Rainfall last 48 hrs 8.6, Air Pressure 1011.5 hPa. River level comparatively high. At HT the mouth was open with in flowing tide. However the depth at the mouth was very shallow, suggesting the mouth would be closed at low tide. This would help to account for the high river level. | |
#7973 | 31 Dec 2012 | Approved |
Notes:
Rainfall last 48 hours 0mm Air Pressure 1018.9 Mouth entrance is quite narrow, <3 metres Vegetation has been cleared around the river gauge near the bridge so that the gauge can now be easily read |
|
#7950 | 5 Dec 2012 | Approved |
Notes:
Atmospheric Pressure 1011.7 hPa Rainfall last 48 hours 7.4 mm Thick vegetation obscures the lower two river gauges, the reading above are a close estimation. WE shall take pruning tools on our next monitoring visit. |
|
#7910 | 31 Oct 2012 | Approved |
Notes:
Rainfall last 48 hours 0mm Air Pressure 1010.0 hPa First Water Level height is an estimate as water was below the silt covering the gauge. Wind direction has been entered as E, however there was no wind, and therefore no direction. This is not an option on the program. |
|
#7851 | 4 Oct 2012 | Approved |
Notes:
Rainfall over last 48 hours 0mm Atmospheric Pressure 1008.9 hPa |
|
#7713 | 11 Sep 2012 | Approved | Notes: Air Pressure 1020.5 hPa, Rainfall over last 48 hours 0mm Preceeding weather has been marked by very high winds (mode W) responsible for deposition of sand on beaches and berms | |
#7503 | 31 Jul 2012 | Approved |
Notes:
Rainfall over last 48 hrs 2mm Air Pressure 1029.7 hPa |
|
#7401 | 9 Jul 2012 | Approved |
Notes:
Nil wind, no direction. Rainfall last 48 hrs 0mm, Air Press. 1022 hPa Mouth wide and deeper than usual Sighting of whales directly off shore of mouth, Mother and Babe? |
|
#7204 | 5 Jun 2012 | Approved |
Notes:
Air Pressure 1018.6 hPa, rainfall last 48 hrs 47.8mm Intense storm on 04/06/12. Rack line shows river height at peak of flood greater than 1.28m. Large waves breaking over berm opposite fishing platform. Mouth is wide, storm waves battering edge of berm, greatly modifying its structure. Wave surge at HT is impeding the outward flow of flood waters. |
|
#7108 | 4 May 2012 | Approved |
Notes:
Rainfall last 48 hours 12 mm Air Pressure 1019.5 hPa River full to height of bank top, high rainfall in upper catchment over last 3 days has produced strong river outflow through recently opened estuary mouth. Large flock of terns resting on river banks at fishing platform. |
|
#6823 | 6 Mar 2012 | Approved | Notes: Atmospheric pressure 1024.1 hPa, Rainfall in last 48 hrs 2 mm. Note very strong winds over the previous week. The height and width of the dune between ocean and river has increased in height and width, with vegetation starting to colonize the dune opposite the fishing platform photosite. Although there was no tidal influence at the time of monitoring, the overnight high tide (1.5m) had pushed the level of the river higher, to leave wet stained sand along river bank. |
