1 October 1990- 10 bottlenose dolphins were
found in Lake Goegrup,2 unfortunately having already died. 8 were rescued,and
freeze-branded 01 to 08 then released under the new bridge. All were males and
measured approx. 2.2 metres in length.
3 February 1991- 2 bottlenose dolphins were
trapped in Lake Goegrup, already freeze-branded 02 and 03. They were released
under the new traffic bridge.
13 January 1992- 1 Bottlenose dolphin found
trapped in Lake Goegrup, already freeze-branded 06,had to be put down due to
horrific sun burns
5 December 1994- 4 bottlenose dolphins
stranded on mudflats at Soldiers Cove , all males, and were freezebranded
12,13,14, and 15. These dolphins were released to deeper water from the old
boat ramp, south of the old traffic bridge
10 December 1995- bottlenose dolphin
freezebranded 12 was observed in a poor condition in Yunderup. This dolphin was
captured and given a vet assessment, and a blood profile taken, then released.
He was found dead on 23 December 1995 inside the Dawesville Cut, cause of death
established by post mortem to be peritonitis.
8 November 1996- A dolphin stranded on the
mudflats of Falcon for six or seven hours prior to being rescued. The adult
2.2metre bottlenose was struggling in water only 15cms deep. Although
distressed, the dolphin was not sunburnt or hurt. The dolphin's condition was
checked by a vet, before he was placed on an inflateable raft and towed to
deeper water. This dolphin was not freezebranded.
13 March 1997- 6 bottlenose dolphins were
trapped in Lake Goegrup, 2 adult females, 1 juvenile female, and 3 males. These
dolphins were freezebranded 01 (a male rebranded from previous stranding), 17
(male), 20 (female), 21 (female calf), 22 (her mother), 23 (male). Number 23
carried an old brand, probably from the 1990 Lake Goegrup stranding which may
have been 05.
29 Sept 97- A mother and her young calf were
rescued from stranding in the shallows in the yunderup branch of the peel
inlet. This is near Coopers mill. Canoeists found the pair about 10am in some
distress. Together with a local resident they used sacks to successfully take
the mother and calf out to deeper water. The mother in particular suffered bad
burns to her back.
8 March 1998 - 3 adult dolphins were stranded
in low water off Mandurah quays during the night. Two were able to be coaxed
out to deeper water and safety. However, the third dolphin needed to be lifted
by sling and caried out by rescuers as it was physically stranded, unable to
move at all by itself. All dolphins reunited once they were in safer waters and
swam off strongly. No sunburn was reported. The dolphin that was physically
stranded had an old freezebranded number on its dorsal, the first letter being
0.
26 March 1998 - A dead dolphin was found in
Mandurah's estuary waters. The dolphin had lost many of it's teeth and so was
very old. It was not freezebranded and no visible signs of injury were
observed. Measurements were taken, 2.57m in length, dorsal height 140mm, body
width 635mm. It was presumed it had died from natural causes (old age)
30 March 1998 - Two dolphins were sighted
stranded in Lake Goegrup, one physically unable to move on mudflats, the other
swimming nearby in a deeper channel unable to escape due to the low tides. The
stranded dolphin was freezebranded number 17, who has been stranded before.
This dolphin had a series of cuts on its head, so regular it was thought they
may have been injuries from a boat propeller. As well as these cuts, it also
had an injury on it's tail, from the stranding. It was decided to place 17 on a
sling and carry him to the deeper channel, to join the other dolphin. Though
obviously exhausted and stressed from its stranding, this dolphin breached out
of the water, once it was released and in safety. As the tides rose overnight,
it was hoped both dolphins would then be able to navigate across, and out of
Lake Goegrup safely. A search of Lake Goegrup and the Peel inlet the next day,
revealed this plan had been successful, and number 17 was seen swimming
strongly with a large pod of other dolphins.
19 April 1998 - A dolphin was seen pushing and
carrying her dead (miscarried) calf on her snout, surrounded by a large pod of
other dolphins in the Peel Inlet.
15 July 1998 - A young calf was seen trailing
prawn netting underneath it, and wrapped around its body, swimming with it's
mother number 22. Initial efforts to catch the calf were unsuccessful and a
full CALM response was planned for the next day. However, on finding the baby
again the next morning, it was clear the calf had been able to escape the
netting by itself overnight. This calf is now named FALLON.
18 August 1998 - An adult dead dolphin was
washed up on San Remo beach. very badly decomposed. No identifying marks or
features could be distinguished.
26 August 1998 - 2 whales were sighted off
silver sands beach inshore, one appearing to be in trouble. Despite the second
whales attempts to be guiding the other out to deeper water, one of the whales
then beached alive. However, it died within an hour and obviously had been very
sick. It was found to be an adult fin whale, approx 15m, 40 tonnes approx,
possibly 30 yrs old, with no visible wounds other than scrapes from being
tossed onto the rough sand repeatably in the rough shore waves. It had stood no
chance of survival.
15 April 1999- A dead male calf was found
washed up on the beach between Halls Head and Falcon. Only approx 4 months old,
it probably died from starvation as it was very emancipated.
15 October 1999 - A dead female 1.64m
bottlenose dolphin was found washed up on a sandbed in the peel inlet. Cause of
death unknown.
27 November 1999 - Decomposed dead adult
dolphin found washed up on the beach at Falcon. Had most probably been caught
in craypot ropes and drowned. Length 2.4m
10 February 2000 - Dead male bottlenose
dolphin found decomposing on Madora Beach. May have been very old as it's teeth
were almost completely worn down flat. Length 2.35m
2 very young calves, possibly stillborns found
dead and badly decomposed south of white hills Dawesville. Lengths 1.m and
1.2m.
26 Febraury 2000 - Mother and calf pair found
stranded in shallow water between the Serpentine and murray river entrances.
People crabbing nearby were able to successfully assist the pair out to deeper
safe waters.
1 May 2000 - Dead male bottlenose dolphin
washed up on the beach 1/2km south of Avalon. Length 2.5m teeth quite flattened
with age.
15 August 2000 - A female short finned pilot
whale washed up dead alone at falcon beach, very decomposed. It was thought to
be already dead by approximately 2 weeks. Length 4.1m. No teeth seen
2 December 2000 - A severely sunburnt dolphin
was first noticed by Dolphin Encounters Mandurah. This dolphin must have been
stranded and been able to eventually work itself free once the tide rose. It
has later been established this was the male dolphin freeze branded with number
15 and his constant companion male freezebranded number 14 was also stranded
and suffered burns. Both dolphins are now recovered.
27th December 2000 - 3 beaked whales stranded
in mandurah. One was found dead at Avalon. The other two were assisted by CALM,
emergency rescue officers, the volunteer dolphin rescue group and many members
of the public, out to sea. One of these whales later restranded at Secret
Harbour and was then successfully rescued and taken far out to sea by boat
beyond the reef. The total rescue efforts took nearly 10 1/2hrs. As neither
whale was reported restranded or dead, it is considered that the two rescues
were successful.
A dolphin with it's tail and body caught in craypot ropes
in the ocean south of the Dawesville cut now owes its life to three mandurah
residents who successfully cut it free.
24 June 2001 - A small male calf was found
dead washed up on Seascape beach. Length 1.37m long. It is thought it may have
run foul of heavy surf and the reef during a recent storm.
Mid to late August 2001 A young calf is
reported to have been found dead washed up in the Estuary, near the Cut. Also on
4 September 2001 - A 2m bottlenose dolphin was found dead on rocks at the Cut
under the Dawesville Bridge.
6 May 2002- A young (almost newborn) male calf still with
foetal folds unfortunately got itself wedged under branches at the side of the
Serpentine river in very high tide conditions due to a storm, and drowned. The
calf was heard calling out in distress to the nearby pod, just prior to its
death.
Winter 2003 - A pilot whale died after
battling heavy seas off Madora Bay
March 2004 - A mother and calf stranded in
Lake Geogorup and suffered severe burns. The calf was unfortunately later found
dead off the Yunderup canal entrance on Friday 26th March 2004.
27th March 2004 - A Gray's beaked whale was
found stranded in a shallow inlet bay immediately adjacent to the Dawesville
Cut. The whale was assisted to deeper water with the high tide. After
restranding the following day still in the Harvey Estuary area, the whale was
herded by boats out to the ocean through the Dawesville cut.
18 May 2004 - The dolphin freezebranded 21 was
seen mourning the loss of her new calf. Her mother also had a dead calf this
year.

2nd August 2009 – Thanks go
out to the many people who reported a calf in the Dawesville cut with a huge
mass of fishing line and seaweed tangled on its body and tail, making it very difficult for the calf to
swim.
We’re happy to report CALM immediately attended on Sunday
2th August and after a lengthy rescue effort was successful in removing the huge
mass that was tangled round the calf
including fishing line and many hooks.
Well done to CALM for a huge effort and their success. We do ask
the public to continue to keep an eye on the calf and dolphins in general in
Mandurah. And PLEASE remove any rubbish you may see in/around our waters.
Fishing line, plastics, ropes etc in particular!
8th
September 2009 -Dead Adult male dolphin found near Mandurah Quays. Was missing all
its front teeth so was quite old.
8th October 2009 -Badly decomposed
young male dolphin approx 6 ft found in shallows near Mandurah Quays.
9th November 2009 - A juvenile
dolphin was rescued from stranding in very shallow waters in cox bay. many
thanks to everyone who assisted!
Weekend following the above stranding this
rescued juvenile dolphin was reseen twice, back swimming alongside it’s
mother (its mother is the dolphin with only half a fin “Uboat” )J
The rescued juvenile has some sunburn on its back and can also be
recognized by a nick out of the back of its dorsal fin about halfway down. A very successful rescue!
2010 NEWBORNS. – As far as I know there
was 4 new calves born and still alive by the end of March amongst the main
estuary/inlet dolphin pods. Of course there is probably more born further
afield in Harvey estuary and Dawesville ocean.
one calf was born late December 2009 one born early January 2010, one
born Feb 2010. One is reported to be born 3rd march in mandjar
bay!
Mothers are dolphin with
nick out of fin half way down, dolphin freezebranded 21, and one with no
identifying marks on her dorsal. Another with very large unusual shape dorsal
may also be a mum.
We believe a 5th newborn is now in
the inlet as of 17th may 2010.
On a sadder note the male dolphin with freezebrand 23 has not been seen
for a long time. He would be in his older age possibly over 30yrs.
12 June 2010 - A dolphin is seen pushing her stillborn or dead newborn calf near the Mandurah marina. Dolphins mourn
their dead and she is likely to stay with the body for several days.
A smaller adult, she may be a first time mother and unfortunately
there is a high mortality rate in first calves especially.
Our MANY thanks to Doug Coughran of CALM for
providing much of the early dated information and Royceart for the lovely
dolphin icons
