The sound of rain was disappointing this morning, and did not look like
clearing for some time. We had an errand to do in the city before heading
further afield and while the rain did hold off, making our umbrellas and rain
coats redundant, it was still a very dismal picture.
We headed off up the highway, turning east onto the Coalfields Highway,
an excellent wide road, fairly recently realigned, taking us up into the
Darling Scarp which still continues to protect the Swan coastal plains from the
extensive inland. Despite the low cloud and busy windscreen wipers, we could
see that we were passing through a very picturesque landscape; rolling hills,
farmlands and thick jarrah and marri forests.
Eighteen kilometres from the South Western Highway turnoff, we turned
south into the Wellington National Park, passing through a further twelve
kilometres of dense forest, until we reached the Wellington Dam.
This was completed in 1931, constructed in less than two years, a
project providing work for the unemployed during the Depression years. In 1944
the height of the dam wall was raised by a metre, and in 1960, a further 15
metres. The wall is now 366 metres across and 34 metres high. Big gates keep
the curious out; we were unable to walk across the wall as I would have liked. The
reservoir has a capacity of 186 million kilolitres of water when full, however was
far from that today.
The dam provided drinking water for inland towns, with a pipeline built
to Narrogin in 1956, and later extended to other towns. Western Australia’s
second hydro-electric power station was built on the Collie River about 400
metres downstream from the dam in 1956, and is still in use today, able to
produce enough power to supply 1,500 homes.
The total catchment of the Collie River covers about 4000 square
kilometres, all eventually flowing into the Leschenault Estuary we visited a
few days ago. The river flows have been boosted since 1903 with water pumped
from the coalmines near Collie, however lower rainfall since the 1960s has
reduced the amount of water flowing into the Wellington Dam. Widespread
clearing for farmland in the catchment over the past century has caused
salinity levels in the water to rise. In 1976 clearing controls were introduced
and in 1979 a re-afforestation program began in an effort to control this
common problem. However the salinity levels continued to rise to a point where
the dam could no longer be used as a source for drinking water, for which it
was originally built.
It is hoped that with continued re-afforestation work, salinity will be reduced
to an acceptable level and fresh water will once more be available from the
Wellington Dam.

Rain cloud |
We jumped the puddles down to the lookout from where we watched the rain
mist lifting from the heavily wooded gullies and out over the reservoir with
its exposed muddy banks. This seems to be the norm for most reservoirs seen on
our travels apart from those in Queensland we visited in early 2011 after the
floods. We looked for the brochures detailing the walks on offer in the
National Park but were unable to find any.
We back tracked to the Coalfields Highway and pressed on a further
eighteen kilometres to Collie, an inland town located 204 metres ASL in the
Scarp with 9,000 folk whose economic wealth comes from coal and related
industry. That comment tends to make one think of a dark dirty dismal
industrial centre, however this is not the impression one gets either entering
the town or spending a little time there. I can well imagine this was not always
so, because for many years Collie was also a rail centre with twelve lines
running through the centre of the town. It still does but the trains are fewer
and far cleaner. The streets are wide and clean, and while it would be an
exaggeration to suggest it is a “lovely” town, one cannot say anything negative
about it. In fact the residential areas we passed through were most attractive,
with many lovely modest new houses and according to those advertised in the
real estate agent’s windows, all reasonably priced.
Collie also lies on the Bibbulum Track, one of the world’s Great Walks, that
which starts at Kalamunda in the Perth Hills and finishes down in Albany,
stretching nearly one thousand kilometres. As we left the Information Centre,
four young men arrived, all with heavy packs on their backs, all wearing woolly
hats, having walked through from Dwellingup, where we were just a few days ago.
The Track brings business to the town and to every other place along the route,
walkers requiring accommodation, hot showers and decent meals to supplement the
plain fare one eats on such a hike.
Back in 1839, the Governor of the Swan River Colony offered a reward for
the discovery of a significant coal deposit. Coal was accidentally discovered in
Collie by George Marsh in 1883 while shepherding for Arthur Perren who had a
pastoral lease on the Collie River. Marsh had gathered some black “stones” from
the Collie River bed to place around his campfire to boil his billy, when to
his amazement they caught alight. Uncertain of the significance of his find, he
reported the matter to Perren who realised it was coal. The source of the
discovery remained a secret until an exploration party organised by David Hay
found coal in the river in 1890. Meanwhile George Marsh had gone west of the
state shepherding, where he died of typhoid in 1892, none the wiser of the
significance of his own discovery. The reward for the discovery of coal was
claimed by Perren and Hay. I guess the good part of this story, even for the
dead Marsh, is that he is remembered for having missed out on the glory, and
the reward. But then as they say, you can’t take it with you.
And just in case you have been thinking that Collie is named for its
coal or the colliers who worked the mines, it is not. The Collie River was
named by Dr Alexander Collie, RN who discovered and named the river in 1829. In
summer, in its natural state, the Collie River was a series of pools as so many
rivers and creeks in Australia are. Now, with massive human intervention, it
can be manipulated to whatever state the bureaucrats decree.
The coal
fields were developed in the late 1890s, but then that early mining was rife
with cave-ins, fires and other horrors. I suspect if we had bothered to visit
the museum I might have learned a whole lot more about these early years, however
it was not really until the middle of the last century that there was really
significant development.
Collie’s
coal mining did not really take its rightful place in Western Australia’s
economy until the settlement was connected to the rest of the world. The first rail
line was completed in 1898 and CY O’Connor, the Commissioner of Railways, whose
name seems to have been popping up all along this coast as I immerse myself in its
social history, saw the coal fields as an essential element in the development
of Western Australia. He considered that if the agricultural lands of the state
were to develop, they would need transport in the form of an efficient rail
network and he saw Collie coal as the most logical fuel option.
The Collie rail marshalling yards, in their day, the
largest in the state, were an important source of employment for the town and
an essential link in the state’s economy for over seventy years. But from 1970
onward there was a steady decline in the size and importance of the Collie rail
operation, mainly due the growth of road transport and the use of diesel for
locomotives.
In 1950,
Wesfarmers Premier Coal commenced business as Western Colliers, producing
energy resources for Western Australia’s mining and electricity industries,
principally supplying much needed energy to the Kalgoorlie Goldfields. The
first coal was produced by open cut mining at Collieburn before the
introduction of two underground mining operations in 1952. The second of these
mines, Western No 2, would become the State’s largest underground mine,
operating for forty two years to produce more than 14 million tonnes of coal. The
biggest single mine was the Western No 5 open cut operation, established in
1970, which produced more than 20 million tonnes during an operating life of twenty
seven years.
In 1989,
Western Collieries was acquired by the diversified agricultural and industrial
corporation Wesfarmers, that which owns Coles and Target, introducing the
modern era of coal mining at the Company’s Collie operations. Underground
mining closed in 1994, and all production was relocated to the efficient open
cut operation at the Premier mine site, ten kilometres east of the Collie
township.
Today
Wesfarmers Premier Coal is the State’s major coal producer, supplying fuel for
45% of electricity generated for the South West Interconnected Grid.
On our
map we noticed other industries near the town: the Worsley Alumina Refinery,
the Bluewaters and Collie Power Stations and the infamous Muja Power Station. This last station is currently very much in
the news, having undergone repair and upgrade at enormous expense to the tax
payer and while partly operation, is unlikely to ever be brought up to its full
capacity. Here in Western Australia this is as big news, just as are the revelations
of the country’s new Prime Minister as he scarmongers using words like “conflict”
in an international context. Still these are early days, and all so
interesting.
We walked up and down the main street of the town and patronised several
businesses, including the busy bakery for calorie ridden pastries. We were delighted to learn about the rather
strange sculpture of the bookmaker, titled “The
Book of Odds” in the main street to celebrate the obscene amount of unchecked
betting activity that went on in the middle of the last century. In 1948, a
policemen sergeant reported that there was evidence that about fifteen
bookmakers were in operation, and that of a population of about 6,000 adults,
he estimated that 1,500 or maybe 2,000 bet regularly. It was police practice to
turn a blind eye.
Now after midday, we headed twelve kilometres north to the Harris Dam
for lunch and a bit of exercise. While the rain had cleared, the picnic
facilities up at the Dam were wet, so we ate inside which we seem to do more
often than not these days. Then we donned coats and sturdy walking shoes and
set off to walk part of the Bibbulum Track, just four kilometres toward Perth,
as far as the Harris Dam hut, and what a beautiful walk it was!
|
Walking the Bibbulum Track |
We climbed above the dam through forest with an under-story of bracken,
banksia and palms along with the usual sort of small scrub that seems to
survive anywhere. Everywhere there was evidence of past logging, ancient stumps
still standing testament to the industry that took place here and sometimes
great dead trunks which would have barricaded the track had Park staff not come
through and cut corridors through the girth. The fallen trees are left to
decompose where they once stood, as they would if humans had never come this
way although it seems such a shame that excellent timber goes to waste. Further
along the track we were pleased to see the grass trees again. At one point I
saw a kangaroo bound away, disturbed by our presence. We spotted a Scarlet
Robin, such a beautiful bird and a Superb Wren, but the other fauna we might
have seen including the normally elusive Red-eared Firetails, Chuditch and Quenda,
were all exactly that; elusive.
I was interested to read on one interpretative panel that there are
around one hundred bird, twenty seven mammal, forty reptile and thirteen frog
species within the forest, but that “foreign species like foxes, cats and
kookaburras” threaten the survival of many of these native creatures. I had
never considered kookaburras to be a “foreign” threat to its fellows.
Further research revealed that the Laughing Kookaburra is in fact only
native to eastern mainland Australia and has been introduced to New Zealand,
Tasmania and Western Australia. Individual birds were released in Perth in 1898
and it is the descendants of these that are considered the enemy of the
Department of Environment and Conservation. I was very sorry to learn this; I
do so love these wonderful birds.
It took us nearly an hour to walk in because I was constantly distracted
by the wonderful fungi along the side of the track as well as some surprisingly
lovely flowers, too early for the spring flower season for which this coast is
well known. Arriving at the hut, a three walled shelter complete with wide bunk
shelves, a water tank, a fireplace and a lonely long drop dunny far away up a
track in the bush, we found a sleeping bag that a tramper had dropped as they
left or forgotten to pick up after a last minute dash into the bush. We moved
it out of the rain but thought it unlikely the owner would return for it. Such
is the life of consumables these days; he (or she) will simply buy a new one.

More lovely funghi |
Our return took us just over three quarters of an hour and we enjoyed
that as much as the walk in. We were so impressed with this short section of
the Bibbulum Track, we thought we might look out for more southern sections,
and would, in theory, love to do the entire walk. Perhaps we would just walk
through forest sections or perhaps just recommend it to those younger and
fitter than ourselves.
We drove up to the lookout over the dam and walked across to the other
side. The Harris Dam was completed in 1990, and like the dam it replaced, took
just two years to construct. It supplies drinking water to approximately 40,000
people in more than thirty towns and small communities on the Great Southern
Towns Water Supply Scheme, including Collie, Narrogin and the far away Hyden
near the famous Wave Rock which is currently on our “Shall we or shall we not”
list.
The dam’s catchment area is 321 square kilometres and it is capable of
holding 72 billion litres, making it the second largest dam in the South West
Region after Wellington Weir. The dam wall is a 37 metre high earth embankment.
We stood at the end of this and looked down upon the wide spillway which looks
as if it has been dry for many years.
Our plans for the day had been far more extensive than that so far,
however the day was already well done and we decided we did not want to rush
through the other attractions on our list. We would leave them for another day,
and so we came on home, just in time to miss the rain which had held off for
most of the day after all.
