AHD estimate only as board is covered with algae & silt

Pale reducing flow out around mouth & slightly to east. Very low water level with large areas of sand exposed in the lagoon. Previous sand projection & sand bar uncovered

#13165 21 Jun 2019 Approved Notes:

Low water level because of tide & reducing flow, dark discharge around mouth with small waves entering & going upstream across the lagoon on G2. East side of channel is sheer sided (up to about .40 high at start of channel)

Remains of the previous sand projection going north into the estuary was visible because of lower water levels

No water over any tracks & flood water has drained from flats around G4, but remains from midway between G5&G4 up to G6

#13135 14 Jun 2019 Approved Notes:

Strong dark outflow from lagoon along wide channel out around mouth & to east. Rough sea sending waves high up on beach resulting in strong longshore drift  which continues to scour  sand from beach area  around mouth which is now lower. Both ends of channel are very wide - most of previous sand projection into the lagoon has been removed but an area remains further to the east. Despite heavy rainfall the flats downstream G4 are draining but extensive flooding occurs upstream to G6. No water over roads or tracks apart from low track which has water only in very low areas

#13077 17 May 2019 Approved Notes:

Mouth open with rocks well exposed, sea moderate but higher waves breaking on sand bar, active longshore drift across with some waves entering up channel into estuary scouring out sand at east side.

Large tongues of sand projecting into lagoon -exposed areas in new formation in front of tunnel

#12901 3 May 2019 Approved Notes:

AHD G6 1.42 @ 08:40

Shallow outflow opening wide over sand build up at entrance - very large amount of sand visible under water in estuary extending past tunnel entrance. sea moderate but some high sets breaking on sandbar about 50m. out & going very high up on beach. Occasional small waves from longshore drift & incoming sw swell going part way up channel to where it narrows down to about 2m.wide. Waves are going over top of high sand build up at mid beach (formerly a narrow projection but now extending towards east end of beach) where water then runs east along an area on top of high sand to slightly lower area where abruptly turning towards ocean it scours out narrow N/S channel - very large amount of sand visible in outflow & back wash in ocean at that area

Water level in downstream of G2 is high, water over top track & nearly up to ocean car park. No water on any roads but at side of OOR between flood markers & GOR. Flats south side of G4 & downstream have visible water cover - further upstream water from runoff (about 30 ml. on 01-05-19) is only in very low areas & drains

#12894 30 Apr 2019 Approved Notes:

AHD G6 1.28 @ 11:45 = both G6 & G2 are the same

Mouth barred- the actual length of the berm without water is not great but only a very narrow very shallow projection is coming out of the estuary where an extensive sand build up is visible extending well into the estuary almost up to the tunnel entrance. Height of berm from estuary is .10 with gradual slope down to ocean. the recent storm has considerably lowered the beach around entrance & up to the sand spit at mid beach

No water over any roads but flats DS G4 have water cover.

#12891 26 Apr 2019 Approved Notes:

AHD @ G6 about 0.96  @  13:58  board covered with silt

Observations made during hi tide & storm surge - wind from SE  8-9 along beach but even stronger turning down channel  Not possible to use Gp1 site so taken from below.

Waves entering from high sea combined with a very high tide. No fresh discharge only shallow salt return over high sand build up in channel. Waves going up to base of dunes all along beach & channel. Entering very wide at mouth & completely across channel. SW swell with over 8m waves strongly impacting east end of beach creating very strong longshore drift & backwash. Waves overtopping high part of beach about 50m from west cliff then turning west & around into the channel meeting incoming waves from SW swell also going down  creating an extremely strong N-S backwash - also whirlpools at start of estuary, this action has left significant depressions in the sand . The wind action has also sent large amounts of sand from the beach down the channel & into the estuary       

#12890 25 Apr 2019 Approved Notes:

AHD G6 about 0.78  - board still covered with silt

Waves entering across a wide area & travelling down channel into estuary -large amount of green water is visible almost to tunnel entrance & can be seen mixing with darker fresh throughout the estuary. Only salt return occurring over high sand build up in channel. Outflow is very narrow & shallow - often no flow at all. Waves going very high up all along beach & entering very wide at mouth. At 15:50 a very strong longshore drift was visible going across entrance -impacting on west cliff & sending strong waves up channel

1 dead Gannet on beach near entrance & about 10 others feeding in area around the ocean sandbar.                                                                                         2 dark grey Pacific gulls feeding in estuary

AHD G6 about 0.98 @ 08:40  AHD board still covered with silt

Observations made close to very low tide 0.1  @  07:12

Very pale thin discharge out to sea & along to sand projection at mid beach. Out flow very shallow - channel about 20m wide .5 to .15 deep. at start of estuary. At mid channel it narrows to about 8m.then becomes more shallow & wider around rocks.Flow spreads very wide as waves enter at mouth. East side of channel has .20m sheer face as it approaches rocks.

Waves have been high up on beach at last hi tide. A large sand projection has formed at mid beach with area of beach behind scoured out. Strong longshore drift from east end travelling to spit where it meets incoming SW swell -large amount of sand visible in waves going out to sea. Only occasional longshore drift across mouth meeting small outflow & strong sw swell resulting in some waves going up the channel - large amount of sand visible in breakers around mouth.     While sea is moderate there are higher wave sets are occurring

#12860 19 Apr 2019 Approved Notes:

Very pale discharge out (mainly salt water return).                                   Outflow very shallow around rocks & entrance. It is wider but also shallow at start of channel from estuary, the previous high sheer east side of channel has been reduced but sand is a lot higher around rocks. Some waves entering & continuing upstream.

Beach rises & falls with deep depressions (N -S direction) -2 bays have formed with a projection out to sea at mid beach. Area at east end has had full impact of previous WSW swell & rough seas extending well back towards dunes. Low water level has exposed large areas of sand on beach but sand bar in estuary is under water.

Many very small fish observed in shallow water beside low track.

#12842 9 Apr 2019 Approved Notes:

AHD G6 1.18 @12:20  (estimate only as board is covered with silt)

Mouth is open but high seas & SW swell (waves over 6m.) are entering completely across entrance & channel & travelling into estuary as well as going up to base of dunes all along the beach. Waves are up to base of dune at Gp1 site. Only salt water is entering & returning - green water extends into the estuary & well upstream of G2. Waves (some over 2m high) going down channel then turn east at start of estuary but  an occasional wave proceeds north alongside of cliff face. Wind about 6 SE along beach but from S along channel  gusts are stronger (7). Large amount of sand blowing into estuary as well as being carried in large waves down the channel . In between waves a large amount of sand is visible in channel with only a very  slight flow of salt water return down below the side of  cliff                

#12820 4 Apr 2019 Approved Notes:

Estimated height @  G6 0.68 - board unreadable because of silt build up

Dark discharge from reducing outflow around the mouth & to west, pale discharge continuing along foreshore to east. Entrance about 50m wide with sheer sides to channel from 1-2 m. high. Sand has built up on east side of channel -also directly downstream of rock. Longshore drift across mouth over sw swell with backwash return & some waves entering up the channel into the estuary. Waves are going high up on the beach at east end of beach which rises & falls creating some deep areas. Height of beach drops as it reaches the mouth

All tracks & roads are without water including low track where an extremely large number of small (1-3 cm) fish were actively swimming. Small fish were observed in all areas of estuary

D.O. levels @ G2 have greatly improved with flow going upstream while monitoring

AHD G2 1.65       G6 1.65  @10:35

Mouth closed but waves have been over berm & up into the estuary @ last hi tide -7 dead eels were stranded trying to cross over to sea. Strong sw/ssw swell impacting at mid beach creating strong backwash with occasional longshore drift.   Wide area of beach near cliff is much lower than that towards east where sand is very high

Water is up to the sides of OCR west of camp ground (which has increased water cover).  Areas of OCR south & further east along return track have deep holes scoured out by vehicle traffic. Water has started to cover small area of GOR between Latrobe creek bridge & start of OCR. Water at side & over OOR at Flood markers.  Water across flats DS G4 but not US G4. Flats around G5 have significant water cover that is not completely visible because of high vegetation

AHD G2 1.57 @ 09:14 but between 1.57 & 1.58 @ 12:35  AHD G6 1.52 @ 08:40

Observations made at low tide.

Mouth opened at low tide between rocks at base of cliff not through the berm sand build up which remained intact. Flow from estuary was coming down through a channel about 3-4 m across widening to 7m where it sharply curved west towards cliff - height of channel east side in that area 1m.  Depth about .10-.20m . Waves had been overtopping the berm at last hi tide & running down west along the beach towards cliff along the sand behind the berm travelling down a previously formed depression. The beach rises & falls creating wide N-S depressions. High wave sets impacting on sandbar & going high up on beach = backwash & longshore drift.

Very large no. small fish in shallow water around estuary & in water at edge of roads. Peregrine falcon at entrance

Continuing rough seas & strong west winds over past days (6.3-6.1 swell height) on 03-11-18) have created a small low berm which was observed formed across mouth around  06-11-18 pm.   The top of the middle rock was still uncovered. Waves had been over topping the berm at the last hi tide & entering the estuary - indicated by  sand & swash line. Beach undulating with some very low areas. Sand very high at east end where sheer sided areas occur at the top of a steep decent to ocean - beach slopes down towards start of berm & entrance. Waves have been up to base of dunes in some areas - indicated by swash line which contained large dense areas of small shells, tiny crabs, shrimp, extremely small Janthina-janthina & larger 'By the wind sailors'.

No water in camp ground or over any roads/tracks. Water up to the ocean car park along low track & up to the side of the recently raised OOR near flood markers (drains & sides of OOR are currently undergoing maintenance)

Flood water occurs on both west & east flats @ Kangaroobie, G4 (Rivernook) flats are under water with wide flow through dip in causeway. US G4 water in drains only up to between G5&G4 . Upstream from there to G5 water covers large areas on both sides of channel. Water just starting to enter upstream of Coxon's track (G5)

AHD @ G6 1.60 @ 07:15 rising to 1.61 @14:58                                           AHD @ G2 1.43 @ 07:15 rising to 1.46 @ 17:00                                                

#12453 19 Oct 2018 Pending Notes:

Strongly flowing dark discharge around entrance & travelling south with some moving east along foreshore.

Beach is undulating with waves going further in low depressions (running north south), large amount of sand in back wash from these areas. Strong longshore drift across mouth.

Heavy local rainfall combined with higher falls in catchment (41 ml. recorded @ G6 -total since 15-10-2018) have greatly increased flow with river flushing strongly. Depth profile showed similar readings from top to bottom of water column at G5 & G4

#12447 15 Oct 2018 Approved Notes:

AHD G6 0.95 @ 09:15  AHD board difficult to read because of silt.

Observations made at low tide. Extremely pale discharge out around mouth over large sand build up - also sand building up in channel. Reduced flow only passing through very narrow gap between 1st & 2nd rock and a larger area over rapids between 2nd. & 3rd rock. Some water passing between 3rd. rock & cliff base

Sand on south side of estuary extending north into estuary.  North wind driven waves (gusts much stronger than 4 ) have cut sheer side to the projection. Sand bar also exposed.  The east side of the channel south of rocks also has sheer side -possibly  resulting from tidal action
