The Snowy Mountains Scheme
To my long-suffering, faithful Aussie reader: I
heard a wild rumour that a person in England reads these pages so I'm
going to try and write the story of the Snowy Scheme as if for somebody
who doesn't know Australia and has never heard of the Scheme. There won't
be many pictures either, as only 2% of the Scheme's infrastructure is
above ground. You are doubtless fully conversant with the story so please
bear with me. Let me know of any inaccuracies you spot. Okay, here we
go . . .
Imagine the map of Australia. There is range of mountains running from
the Cape York Peninsula way up in the north all the way down to the south
coast. The Great Dividing Range, as it is called, sits about one hundred
kilometres inland from the east coast. Further south it incorporates the
Blue Mountains and the Snowy Mountains. Rainfall to the east of the mountains
is reasonably plentiful but when the clouds rise over the range they are
unable to hold as much moisture so they drop it as rain or snow on the
mountains. The farmers on the fertile land to the west of the range, therefore,
are in a dry air stream and frequently suffer drought. This has always
occurred, it is nothing to do with Australia's present drought which has
made things infinitely worse.
Early in the 1900s there was a more severe drought than usual and the
people to the west of the mountains became desperate. They knew that large
quantities of rain and snow fell on top of the mountains and that much
of it found its way into rivers which flowed east to the Pacific Ocean.
To the desperate farmers that was a terrible waste and they began to wonder
whether some way could be found to divert those rivers their way. The
politicians of the day were also interested because much more food could
be grown in the rich lands of the River Murray basin if more water could
be made available.
Surveyors went into the mountains on horseback, took measurements and
bored holes to test the rock and came to the conclusion that such a scheme
was possible. Civil engineers became involved and realised the enormous
potential for a win-win situation. If all that water high in the mountains
could be made to pass through turbines as it descended, the result would
be megawatts of electrical power without burning any fuel. So, water to
where it was needed, electricity as a by-product and no fuel costs. (Today
they would also add, "and no greenhouse gases".) The water would
emerge to the west of the mountains as pure as when it fell from the clouds.
What politician could resist the glory - and votes - that such an outcome
would bring? None that I can think of, anyway.
Very ambitious plans were drawn up to carry out a larger civil engineering
project than had ever been attempted in Australia, or perhaps even in
the world. The Commonwealth Parliament passed an Act to create the Snowy
Mountains Hydro-electric Authority and appointed a man called William
Hudson to run it. This was way back in 1949, only four years after the
Second World War had ended.
You might be thinking that it all seems a lot of fuss just to drill a
tunnel under a mountain and divert a river. Well, it wasn't quite
that simple. To give you a true idea of the magnitude of the project that
William Hudson undertook, it involved:
• Building 16 major dams
with a total storage capacity of 7,000 gigalitres. That's thirteen times
the volume of Sydney Harbour.
• Drilling 145 kilometres of interconnecting tunnels through
granite.
• Building 80 kilometres of aqueducts.
• Building towns for construction workers.
• Relocating complete towns which would otherwise be inundated
by dam water.
• Building hundreds of kilometres of new roads through densely
forested mountainous country.
• Installing 7 hydro-electric power stations, two of which
would be deep underground. Altogether there are 31 turbines.
• Installing one pumping station (gravity takes care of
the rest).
• Bringing to Australia 60,000 workers from more than 30
countries to work on the scheme with 40,000 Australians.
So, as you'll see, it was not something
William (later Sir William) would do one Saturday afternoon then go home
for his tea.

Lake Eucumbene, the main storage reservoir
for the Scheme, was down to 14% capacity. A row
of trees that had previously bordered a street in the century-old village
of Adaminaby were half
exposed. The village had been replanted eight kilometres away. A hundred
buildings were moved.
The Snowy project took twenty five years
to complete. It finished on time and on budget in 1974. It cost $820 million
and one hundred and twenty lives.
Each year the Scheme delivers an average of 2,360 gigalitres (four times
Sydney Harbour) of water for crop irrigation west of the ranges while
generating 4,500 gigawatt-hours of power. Since this power is fed into
the national grid, the Scheme displaces 4.5 million tonnes of greenhouse
gases each year.

The Tunnels.
How does it all work? Several rivers, amongst them the Snowy, are dammed
high in the mountains, flooding valleys to form lakes. All the lakes are
inter-connected via underground tunnels. The largest lake, Lake Eucumbene,
stores any excess water from all the other dams for future use. The water
is piped through underground tunnels down to the power stations. Water
from higher up may drive one power station, then lower down, a second
power station. When its energy has all been converted to electricity,
the water is stored in reservoirs low down on the western side of the
mountain range, ready to be released into the Murray or Murrumbidgee Rivers
from where it will flow to the irrigation areas.
In a completely unexpected way, this engineering marvel changed the nature
of Australia for ever. Workers came from all over the globe to work together
on the Snowy Scheme. Remember, just four years earlier many of those same
men had - literally - been trying to kill one another in World War II.
Now they worked side by side in rugged, inhospitable terrain. The work
was hard and the temperature varied from freezing in winter to scorching
in summer. Many lived in primitive conditions, some under canvas. But
work together they did and enriched Australian society by bringing their
own mix of ideas, skills, accents, cultures, cuisine, dress, etc. It was
the beginning of what is today called our multicultural society and Australia
is better for it.
The Snowy Scheme has, justifiably, always been regarded with great pride
as one of the greatest marvels of the modern world, however there is a
negative aspect, one that you'll never read about in all the glossy brochures.
The Snowy River used to be legendary, one of Australia's mightiest and
wildest rivers. When the Scheme dammed its head waters it was all but
destroyed. In some places only 1% of the original flow remained, a trickle
meandering around the wide, sandy river bed between slime and weeds, the
banks cluttered with exotic (in the sense of 'foreign') willow trees and
blackberries. The people living along the river's course battled for years
for more water to be released into the lower Snowy. It was a one-sided
battle against politicians who didn't care and powerful commercial interests.
In 1998, (due to a political crisis, I believe) they won a break-through.
The governments of the states of New South Wales and Victoria which, between
them, own 87% of the Scheme, agreed to incrementally release more water
into the Snowy until its flow reaches 21% of the original by 2010. The
river needs 28% of its original flow to remain healthy, according to scientists,
but it's a start. Also, the willows and blackberry bushes were to be removed
over a 60 kilometre stretch of the river and native trees planted in their
place.
The picture of the lower Snowy River shown from the Dalgety Bridge (Page
42) looks sad, but at least there is some flow, and there will be more
by 2010. If, that is, the politicians keep to their agreement under increasing
pressure from the current drought and don't cave in to the insatiable
irrigators. Any bets?
So there you have it, the Snowy Mountains Scheme, an engineering marvel
without doubt, but it has left opposing interests squabbling over the
water. The governments which own the scheme are promising more water for
the Snowy and other affected rivers, and more water for the irrigators.
This at a time when rainfall is declining and the dams are all extremely
low. Surely even politicians can see the nonsense in that? When push comes
to shove the Scheme owners will come down on the side of the irrigators
as that water first produces electricity then goes on to grow export crops.
Water released much higher up into the Snowy looks pretty and is good
for the environment . . . but earns no revenue. I'd guess it will eventually
lose out . . . unless there are enough votes involved.
A Trip Around The Mountain

Australia's highest town, Cabramurra. Weird,
isn't it? The roofs must be designed to prevent
snow building up. They all face west - to collect the afternoon sun, perhaps?
The gash in the
hill behind is a fire break.
One
day we took a circular drive covering 320 kilometres, effectively encircling
Mount Kosciuszko. On the way we visited Cabramurra, a town built for the
Snowy Scheme workers and the highest town in Australia. It was 5,000'
up in the mountains. A southerly was blowing strongly and it was very
cold. It was a strange town which seemed totally deserted. The picture
of Cabramurra (above) was taken from a weather station on the peak above
the town on the site of the old school. God help those poor kids if the
weather was often like it was the day we visited! The site is totally
exposed. The anemometer (wind gauge) pictured was part of the weather
station. It might give an idea of the wind strength.
We also visited a village called Adaminaby and chatted to the attendant
in the petrol station. The town had originally been situated on the bed
of what is now Lake Eucumbene. She urged us to visit the site and we did.
The top picture above will give you an idea of what we saw, though it
can't really convey how very low the water level was. We found a large
pontoon high and dry, moored by a heavy cable a good hundred metres away
from the water. A sign mounted on it pronounced that it was a private
warf and that moorings and boat hire were available. I wonder, will it
will ever float again?
We saw much fire damage on our drive. Fire, of course, is a part of the
Australian life cycle for many plants. Gum trees are seldom destroyed
by fire and will recover in a few years. What we saw, however, were whole
mountainsides of dead trees. They were not blackened but a silvery grey
colour and entirely leafless. We were told they were Alpine Ash trees
and that they don't recover from fire. However the fire does burst open
their seed pods and when everything has cooled down, many germinate and
saplings spring up around the skeletons of their dead parents. Sure enough,
there were multitudes of saplings of about two metres in height around
the dead trees, but as the forest burned four years ago it is going to
take a very long time before it fully recovers. Eventually the
old trees will fall, rot away, and their nutrients will be absorbed back
into the soil to benefit their offspring. Those that don't fall across
roads, that is, and that's a worry. Much of the road we travelled was
lined on both sides with dead trees.

Dead Alpine Ash trees to the horizon.
We initially thought that Alpine Ash was
a Northern Hemisphere import to Australia but some Eucalyptus native trees
are known as Ash because of a resemblance to the European trees. That
explains why all the saplings looked like gum trees - they are. This species
just adopts a much longer-term solution to surviving fire.
Our day's drive was rather like a roller coaster ride. One minute we were
5,000' up, the next we down at 700', then back up again. At least we weren't
dragging the caravan that day. We met some scary drivers, too. We were
climbing a steep hill and approaching a sharp right hand bend. We had
a mountain on our right side and a precipice on our left. Suddenly a car
came screaming around the bend from the opposite direction far too fast,
sliding across to our side of the road. The driver saw us quickly - I
was driving with headlights on for just such an eventuality - and swung
his wheel to the left. His back end broke away and his car slewed sideways
for an instant before recovering just in time and shot past us, still
going like a rocket. We both saw the driver. He wasn't a young hoon, he
must have been at least my age (30 years and 423 months). It looked like
he had his wife with him - I hope she gave him a good serve.
As we turned onto the final leg of our drive we could see the high mountains
in the distance and . . . was that snow? Somebody had earlier told us
there may be snow at the weekend. The day felt bitterly cold. The temperature
had not risen above 10°C until
well into the afternoon and the chill of a strong
south wind made it feel much colder. Had I had the brains to wear sensible
clothes instead of shorts, T-shirt and sandals, I might have fared better.
Anyway, we decided that snow three
thousand feet higher up was quite on the cards. When
we got a lot closer we had another look through the binoculars. Our 'snow'
was actually just bare granite above the tree line. What a disappointment.

What we saw, and . . .
. . . what we thought we saw.
Stop Press: We
later discovered it had snowed on the top, but the snow didn't
stick.
Our final call was at the 'Murray One' Hydro-electric Power Station and
some amongst you will be delighted to hear that all the interesting photographs
that I took for you came out black because I'd accidentally knocked a
setting on the camera. However, before entering I did take one picture
from the road above the power station which you can see below.
There are ten turbines at Murray 1 which is the second largest power station
in the Snowy Scheme and capable of supplying approximately 1,000,000 homes
according to the glossy brochure. The 'tailwater' (the water that has
already passed through the turbines) runs out into a channel which feeds
it into a reservoir called the Murray 2 Pondage. This pond - which is
actually a dammed lake - is about 600' above the level of the Murray 2
Power Station and that head of water is sufficient to drive the turbines
in Murray 2. The tailwater from Murray 2 is stored in another reservoir
for controlled release into the Murray River to be used for irrigation.

The Murray 1 Power Station. Water under
great pressure enters through the pipes driving ten
turbine generators which convert the water's energy into electrical energy.
The electrical energy
is boosted to 330,000 volts in transformers before being fed to the grid
by the transmission lines
seen against the sky. The tailwater exits into a channel in front of the
building on its way to
the Murray 2 Power Station and finally the Murray River for crop irrigation.
At the rear of the building was a driveway
with a notice forbidding people to walk down it or alight from vehicles.
The driveway ran behind a row of ten 330,000 volt transformers so, naturally,
I strolled down it to have a look. If I'd had a heart pacemaker, a sign
advised me, the magnetic fields from the transformers could mess it up
and perhaps kill me. But I don't have a pacemaker and I knew that the
power station was not operating on a Sunday afternoon because the demand
was low. Hydro power stations can start up in three minutes so the Snowy
output is largely used to supplement the coal fired stations at times
of peak demand. Or so the lady in the café told me, suppressing
a yawn.
Another Go at Kosciuszko
I told you earlier that we hoped to have another
shot at reaching the summit of Mount Kosciuszko. When Tuesday dawned cold
and clear we decided to give it a go, and by 09:45 we had driven to Thredbo,
parked, and ridden the chairlift to the start of the track. This alone
was a major accomplishment for us. Well, for me anyway, I'm not
a 'morning person'.
Let me say at the outset that this is not a difficult climb.
The chairlift had done most of the work before we'd even started, by lifting
us 1,860 feet up from Thredbo. All we had to do was cover the 6.4 kilometre
walk to the summit, ascending 950 feet in the process, and then walk back.
So, rounding off, about a 13 kilometre walk which incorporates a 1,000'
climb (as you go down sometimes, then have to regain the lost height).
To make it even easier, all the rough bits are ironed out by the steel
walkway.

This stuff was a dream to walk on, and
it went almost to the summit.
At the foot of the final
leg to the summit we came across some men with trucks and a back-hoe,
building a public toilet into the hillside. Talk about an anticlimax!
There we were, thinking how well we'd done, miles from anywhere and on
the roof of the world (well, it felt like it) and there's a bloody construction
site.

I've been in some pretty high toilets but they don't
normally boast about it.
Okay, so it was really "Rawson's Pass" but you gotta have some
fun.
Anyway, 11:30 saw us standing
on the highest point on the Australian mainland. (I saw it so described
somewhere. Is there a higher point in Tasmania, or on another Australian
island? I don't know.)

The three of us on the peak of Mt. Kosciuszko -
that's good old Alice, our GPS, I'm holding.
Two of my Bright Ideas
Gentlemen, this is for you if, like me, you are co-opted to push a supermarket
trolley while your wife picks up and puts down every item in the shop.
How many times has she sent you to look for toothpaste, or apples, or
a 60 watt light bulb . . . and then totally vanished? Frustrating isn't
the word as you roam the isles in search of her, trying to negotiate a
passage between trolleys abandoned in the centre of an isle by women while
they stand back and gaze at the shelves opposite, or worse, gossip in
a group, oblivious to everyone else. Technology has provided an answer
and applied it to cars. Does your car have central locking? You click
a button on the key fob, the indicators flash and the doors lock/unlock?
Suppose the car manufacturer supplied you with a small device that also
reacted to the code transmitted by your key fob alone. You pin
it to your wife and when she pulls that disappearing stunt, you simply
press the button and from somewhere in the supermarket comes a piercing
beeping similar to a road work vehicle reversing. You then simply home
in on the sound and when you can see her, cancel the signal with your
key fob. No more wandering the isles while your stress levels rise, searching
in vain for the Little Woman. Additionally, when you stop to
look at interesting stuff in the hardware department and she
immediately vanishes with a loud sigh - she does, doesn't she? - you can
instantly locate her when it suits you.
All you have to do, dear reader, is find some way to prevent
her unpinning the device and leaving it under the broccoli
in the chest freezer. Then we'll patent it.
After that we'll work on a loud horn, the type with a large rubber bulb
that you squeeze, and have them fitted to all supermarket trolleys. It
would then be a joy to find a trolley blocking an isle. Your job, dear
reader, is to find a way of preventing nasty little children from using
them. Then we'll patent it.
Perisher Valley and Charlotte Pass
The day was bright and sunny with fluffy white clouds chasing each other
across the sky; too good a day to waste. So we packed up and headed for
Perisher Valley and Charlotte Pass. We were duly relieved of $16 as we
entered the Park and carried on climbing towards Perisher. Soon we saw
solid, low cloud ahead, hiding the mountain tops, and in no time visibility
deteriorated and fine rain covered the windscreen. We drove through Perisher
where nothing seemed to be happening and continued up to Charlotte Pass.
The road finally ended in a loop - nowhere to go but back. We could see
nothing of what was probably stunning scenery. The Charlotte Pass turn-off
was only a short distance back so we turned onto it and drove down a steep,
narrow concrete road towards some roofs we could see through the murk.
The place looked deserted and the concrete gave way to gravel and mud.
We drove around and the only sign of life we saw was two rabbits that
were not the least bit worried by our clattering diesel.
About to leave, disappointed, we spotted lights on in a building which
looked like it might serve coffee. The outside temperature was 7°C
and the wind was blowing the rain horizontally. We
made a dash for the door and found ourselves in a large, warm room
with a cheerful fire burning. It turned out to be the Stillwell Lodge.

The restaurant and lounge in Stillwell Lodge. A
cheerful place that gave us a lovely welcome.
We were their only visitors
and the staff gave us a wonderfully warm and friendly welcome - and
served us coffee and muffins. One wall of the room consisted entirely
of windows and we sat and watched the rain driving past and felt very
snug.
On finally leaving the lodge we drove back down towards Perisher which,
like other alpine towns, was totally geared up for winter sports. Like
Thredbo, it had an enormous but empty carpark. There didn't seem to be
anything to see or do so we continued on back, quickly leaving the rain
and mist behind us as we descended.
We decided to explore a sealed but unsigned road that we came across.
It went for miles and miles, sometimes along precarious ledges cut into
the mountain side. It was totally deserted but since it must have cost
a fortune to build, it must lead somewhere. Eventually we came to the
end - at the Guthega Hydro-electric Power Station. There were no signs
telling us to shove off so we parked in their car park on the banks of
the Snowy River and ate our lunch. The river was but a trickle as it approached
the power station, but then the station's tailwater joined it and instantly
it became a happy, swirling, turbulent torrent. The water that left the
power station had been dammed upstream and piped down to the turbines,
so it was the Snowy's own water which rejoined it.
The river's joy was to be short-lived however; a few kilometres downstream
it was again dammed at the Island Bend Pondage. This time its flow disappeared
underground, en route to the Geehi (G-high) Dam and then on
to the Murray 1 Power Station, the Murray 2 Power Station and finally
the Murray River for irrigation. We looked at the Snowy below the Island
Bend Dam and found no flow at all. Had there been, it would have flowed
into the Jindabyne Lake. Another dam, no escape.
You've probably noticed that my view of the Snowy River Hydro-Electric
Scheme has become tarnished since I first started this page. Initially
I was taken in by the propaganda put out by the P. R. people employed
by the Scheme. Certainly it is a marvel of engineering, but that's only
one aspect of it. Before we left Jindabyne - and not without regret, let
me tell you - I bought a book which describes the fight for the Snowy
River when it was finally discovered that the Snowy River Authority was
to take practically every drop of water from the river for itself. It's
not a pretty story and it certainly gives the lie to the glossy brochures.
Neither does it paint many of the politicians involved in a good light.
Should you be interested, it's called Snowy River Story by Claire
Miller. Claire is a senior journalist for The Age newspaper.
The book is available from ABC Books.
That's it on the Snowy Mountains, the Snowy River and Jindabyne. I hope
we return one day but now we head to the National Capital, Canberra.
We have a link to that Australian
classic poem, The Man From Snowy River, below.
