#13649 20 Mar 2020 Approved Notes:

Mouth closed but an illegal opening occurred on 19-03-20 which created some outflow out for a short period before the channel closed up again by early am 20-03-20

About .30m of last rock above water level at start of river

Water over increased area of top track, low track has water up to ocean car park. Campground has no visible water but very small puddle on north side of OCR before bridge. No water visible on G.O.R.    Small area of shallow water flowing from river is travelling north across OOR  - vehicle access was still possible

#13608 7 Mar 2020 Approved Notes:

Observation taken @ low tide

Sand height has increased between mid beach & mouth. Beach shape has changed, higher @ mid beach with broad projection extending slightly out to sea, while area towards mouth is higher - the area to east is lower & undulating. A sandbar is running parallel to shore about 40m. out, starting from the projection & continuing close to mouth

Upstream flats up to G4 are starting to flood . No water over OOR nor in area upstream G4 apart from small area between G5& G4

#13605 1 Mar 2020 Approved Notes:

Observations made @ Low tide

River perched-some waves going up into river with return to ocean. Waves occasionally overtopping all along beachfront. Previous very rough seas have over topped beach front & travelled down wide shallow depression behind  entering river channel on both sides of rocks - action of backwash to ocean has reduced height of beach front near mouth & created a very low gradual rise up to the start of the river

Seal on Princetown beach 02-03-2020

#13586 21 Feb 2020 Approved Notes:

Reducing outflow carrying a large amount of sand. Then travelling  along foreshore to east Also lighter discharge going to west.Height of beach from mid beach to mouth has increased but from mid beach where it is highest to east the end  it is much  lower. Waves from last high tide have been overtopping & travelling along a wide shallow depression to enter channel around rocks. Sheer east side to channel near mouth indicates a strong flow at last change of tide

#13606 11 Feb 2020 Approved Notes:

Fast flow out from receding tide & reduced wave height. Slight discharge to east.     Mid beach highest area -undulating to east end. Depression between beach front & dunes remains.Waves have been travelling down this area & entering river channel on both sides of rocks (confirmed by swash line)

Heavy wet fog with poor visibility

Large patches of seagrass & algae along SE & E side of lagoon. Large areas of algae forming in Latrobe creek wetlands

1 dead flounder near river channel -stranded

#13552 27 Jan 2020 Approved Notes:

Strong longshore drift meeting outflow & incoming SW swell =large waves across entrance with some covering rocks  & going up channel into lagoon.  Overtopping waves at east end of beach have created a wide depression between beach front & dunes. Tidal range for 27-01-2020 was between 1.13 @ 02:33 & 0.17 @ 19:57

#13551 24 Jan 2020 Approved Notes:

Very shallow outflow out over increased sand build up at entrance & along channel. Very rough sea with occasional very high waves creating back wash & strong longshore drift which meets incoming SW swell & slight outflow = some small waves entering along east side of channel. Beach front very high at east end of beach but over topping waves have made a very large pool in the wide lower area between it & the dunes, this wide area extends west towards entrance.

Bittern was sighted near flood markers on Old Ocean Road on 19-01-20  (Mark Cuthell)

#13512 17 Jan 2020 Approved Notes:

Very pale discharge out only around the mouth. Increased sand build up at entrance & along channel. Flow very shallow & narrow except where it becomes very wide downstream of rocks. Occasional long shore drift across entrance & some small waves entering & travelling along east side of channel into lagoon

Very large no. of small 2-3 cm. fish + a few larger ones in shallow water along east side of lagoon

16-01-20- extremely thin dead Petrel washed up on ocean beach

#13494 7 Jan 2020 Approved Notes:

AHD board @ G6 covered with silt -unreadable

Very pale narrow, shallow outflow curving to east out over high sand build up. Waves & longshore drift impacting across entrance. Large amount of sand visible moving in flow down channel. Sand bar exposed also very large sand area projecting into lagoon south side of lagoon.

Edge of channel directly downstream of rocks has sheer east side

Sand high & projecting out to sea @ mid beach & continuing on to east end. Waves have overtopped beach front in this area & run down shallow channel in sand towards entrance

#13468 19 Dec 2019 Approved Notes:

AHD board @ G6 covered with thick silt -Unreadable

Dark discharge flowing out over an increased height of sand buildup around mouth & to south. SW swell impacting on west side of sand projection mid beach creating backwash & longshore drift which is mixing with incoming swell causing small waves up to rocks then low against east side of channel continuing around & across front of large sand projection to SE corner of lagoon. Area east of 1st rock has been filled with sand & water only flowing through narrow gap between !st & 2nd rock with a larger area of flow against cliff.

Very low tide has exposed large areas of sand on ocean beach & in lagoon where areas of algae occur along east side of lagoon. Algae is also covering areas of both west & north wetlands

#13453 13 Dec 2019 Approved Notes:

AHD G2 0.50    AHD G6  1.00 @  11:45

Outflow reducing - dark discharge only around entrance & south out to sea. Sand has built up in channel & at mouth. As a result of wave impact & recent short time swell times the beach has dramatically changed with very high /wide build up of sand projecting a long way out to sea from about 50m from entrance to east end.This build up has high front to sea & a large depression behind the front extending towards dunes. South west swell is impacting on start of projection & causing some longshore drift back to west across the mouth. The beach from the start of the projection to mouth is lower & has formed a bay

#13429 22 Nov 2019 Approved Notes:

Dark discharge out mainly around the mouth -slight paler water along shoreline.

SW /WSW swell = occasional longshore drift to mouth creating small waves along east side of channel into the lagoon. Mid beach has 2 high areas of sand the most easterly one projecting out to sea. Waves going over this have created a small area of retained salt water further up the beach. Beach is undulating N/S with depressions allowing waves to go further up on beach & scour out sand with backwash

Sand on south side of lagoon well exposed extending far into lagoon. Separate sand bar closer to G2 is also exposed. The area on east side has a very large amount of green algae covering dying sea grass. Latrobe wetlands also has algae over most of the water

#13408 13 Nov 2019 Approved Notes:

AHD G6 2.64 @ 14:50

Dark discharge mainly around mouth, paler going east along foreshore.SW swell 14-13 sec impacting most of the beach except for around the mouth which is receiving the resulting longshore drift crossing & producing small waves down channel where sand being carried in outflow is visible. Beach has many wide deep north/south depressions caused by wave impact & backwash

Very large area of sand extending north into lagoon but sand bar is not visible

Extremely large number of Bluebottles in swash line all along beach

#13395 10 Nov 2019 Approved Notes:

AHD G6 3.24 @ 14:28

Very dark strong discharge out around the mouth for about 100 m. also continuing a long way to the east along the shoreline. Eastern end of beach covered with dark silt. The strong outflow has created sheer east side to channel about 1 m. high above water level (87 ml rain @ G6 over past 8 days). Beach is undulating & scouring areas especially at mid beach where backwash is taking out a lot of sand  -waves in all directions at this area creating occasional longshore drift across mouth. Large amount of sand build up remains downstream of rocks but is being covered by outflow & entering waves. More erosion on east face of Pt. Ronald.

Large areas of deep flood water covering large areas from G4 & G5 (also some between G5 &G6) but very little downstream G4. OOR only had slight flow across near flood markers (run off only.

#13382 5 Nov 2019 Approved Notes:

AHD G6 1.29 @13:20

Outflow reducing but dark discharge out around mouth & along foreshore to the east. More sand visible in channel & larger build up down stream of rocks . Occasional longshore drift across mouth. Sand is wide & high at east end of beach with a slight bay forming

Low tide - sandbar in lagoon slightly exposed. Large amount of rotting vegetation along waters edge east side of lagoon also remains of dead Wallaby/Kangaroo?

#13383 18 Oct 2019 Approved Notes:

AHD G6 1.64  &  08:30

Some flow out but difficult to access Gp1 site because of near gale force gusty wind from NW. Wind coming in all directions depending on location - but mainly across lagoon to SE cr.  Very strong down channel driving large amount of sand into sea. Very high & low tides during 18-10-19 with SW/WSW swell of between 12-13 secs. duration impacting mainly @ east end of beach creating longshore drift to  mouth where backwash was rolling sand all along the edge of the channel

Only 1 photo because of conditions

#13361 12 Oct 2019 Pending Notes:

AHD board unreadable

unusual conditions with ESE swell 6-7 sec time duration. Very low water levels uncovering a very large sand build up in lagoon. Outflow very shallow over large wide area at entrance but channel deeper upstream rocks. Continual longshore drift across mouth. Beach front very high at mid beach

#13336 20 Sep 2019 Approved Notes:

AHD G6 about 2.20    G2 about  0.28 AHD boards covered with silt & debris = estimate only

Dark discharge out around mouth, along foreshore turning out to sea at eastern end of beach. Moderate SW swell impacting east end of beach & longshore drift across entrance -sand has built up higher at mid beach.. Low tide has exposed sand bar in lagoon also decaying vegetation scum covering sea grass along edge of low track. North wind is driving waves into SE corner of lagoon.

Continuing erosion occurring on cliff face



#13274 23 Aug 2019 Approved Notes:

Reduced dark discharge out alongside foreshore extending far to the east.   High seas earlier this week have created a high beach area at mid beach & increased sand build up at entrance. The east end of the beach has been scoured out & is lower than previously. Waves from rough sea are impacting on beach creating strong longshore drift that goes over the outflow creating small waves that travel up channel into lagoon

Flood water  is draining but levels remain high upstream G4

Dead Shearwater on beach near entrance

#13273 16 Aug 2019 Approved Notes:

AHD G6 -flood level over top of pole

Dark discharge out along foreshore to east. Strong & dark  along channel -east side about 30-50 cm sheer face. Waves impacting high on beach causing longshore drift to cross over top of discharge & send small waves down east side of channel & enter lagoon

Heavy rainfall has caused deep extensive flooding upstream of G4. but none affecting OOR down stream

#13243 10 Aug 2019 Approved Notes:

AHD G6 2.50  @ 10:53

Dark discharge out to east along foreshore. Waves occasionally going very high up on beach. Very strong longshore drift going over top of outflow & impacting on cliff face. Wind gusts of over 7+ carrying sand off the beach into channel & lagoon. Wind much stronger along beach but more sheltered from SW  near cliff

51 ml rainfall recorded @ G6 from 07-08-19 to 11-08-19

#13242 7 Aug 2019 Approved Notes:

AHD @ G6  1.93 @ 09:32

Dark discharge out along foreshore & continuing to east. Waves from last hi tide have been well up on beach where more sand has built up at mid beach with wide depression between there & east end. More sand has also built up along east side of entrance. Because of low water levels large areas of sand have become exposed in lagoon & inlet pipe on auto monitor at G2 is well above water level. Waves from longshore drift across entrance are crossing over outflow & combining with WSW/SW swell resulting in very small waves entering channel around rocks.

Erosion continues on S & SE face of Pt Ronald. Large build up of algae or duck weed? at west side of northern wetlands below township.

#13227 28 Jul 2019 Approved Notes:

AHD G6 2.73 @ 09:44   Flats upstream of G4 have deep water cover but down stream G4  flats have very little water

Dark discharge out along foreshore to east, small waves entering along east side of entrance/channel into lagoon with some longshore drift occurring. Large amount of debris has been cast up on the side of low track & new scour holes have been created by backwash caused during storm surge on 23-07-19. Sand has now become higher around east side of entrance & edge of channel now slight gradual slope

#13226 23 Jul 2019 Approved Notes:

South west swell with HIGH seas - some waves over 7m. impacting beach & entrance, travelling completely across channel into lagoon where part of surge turns to east & very strongly impacts on east side of low track rising high into vegetation. More of the surge continues to north then turns west to rise high & wash over the fishing platform at G2. Backwash from initial impact on east side of lagoon travelled directly across & impacted on western cliff face

#13208 19 Jul 2019 Approved Notes:

Very strong dark discharge out around mouth & to east, increased flow caused by very low tide 0.17 @ 06:31 - large amount of foam over exposed rocks & beach at east end of beach. Despite strong outflow waves are entering & travelling down sheer east side of a  25-30m. wide channel (.50-1.00m high) which is collapsing into the flow. At the start of the lagoon waves turn sharply east travelling over the increased sand build up resulting from recent very rough seas. Waves in all directions at entrance & large amount of sand moving in the flow along the channel. Area directly around mouth has been lowered & more of the old breakwater post has been exposed
