The Snowy Hydro Scheme

Alright. So, today’s Aussie fact. It’s all about the Snowy Hydro Scheme. And so, my thought pattern was, okay, the phrase is ‘on thin ice’. What is there in Australia that is ice or snow or the cold that I can talk about? And I thought about the Snowy Mountains, and then I thought about the Snowy Mountain Hydro Scheme. So, I wonder if you guys have heard about this.

So, what is it. The Snowy Hydro Scheme is a hydroelectricity and irrigation complex in south-east Australia. The Scheme consists of 16 major dams, seven power stations, one pumping station, and over 225 kilometres of tunnels, pipelines, and aqueducts that were constructed between the years of 1949 and 1974. So, (it) went for about 25 years.

Astonishingly, only 2% of the construction work is visible above the ground. It was completed on time and in budget in 1974 at a total cost of $820 million dollars, which today, is the equivalent of more than $6 billion dollars. Pretty Penny.

So, this scheme was the largest-ever engineering project undertaken in Australia and was overseen by Chief Engineer, Sir William Hudson. Around two thirds of the workforce employed in the construction of the Snowy Hydro Scheme were recently-arrived immigrant workers desperate for work who originated from over 30 different foreign countries. The total number of workers on the Scheme was more than 100,000 in that 25-year period, and the official death toll reached 121 people. I don’t know if that’s a lot or if that’s not very many. Sounds like a lot.

At the completion of the project, the Australian government maintained much of the diverse workforce and created the Snowy Mountains Engineering Corporation, SMEC, which remains an international engineering consultancy company up to today.

So, why was the Snowy Hydro Scheme built? You know, why was it put into place?

The Snowy Hydro Scheme was implemented to solve a yearly problem for farmers and inhabitants of south eastern Victoria. So, every year here in the snowfields in the Australian Alps the snow would fall on the Great Dividing Range and it would melt in spring time and summer time obviously, and then flood the low-lying flood plains and river flats in places like East Gippsland in southeast Victoria as the water flowed out into Bass Strait and into the Tasman Sea. Thus, each year, farmers didn’t know if their crops would be ruined by these floods or not.

In order to divert the excess snowmelt water and spare the farmers their yearly headache, the Snowy Hydro scheme was implemented, and this had numerous benefits including channeling the water away from the farmers crops into the Murray and Murrumbidgee River irrigation areas, which allowed farmers to access this water via the irrigation systems, and also, they were able to harness the power of the water and turn into electricity using hydroelectricity. Right?

So, how was this done? The water falls about 800 meters and travels through large hydroelectric power stations, which generate peak-load power for the Australian Capital Territory, New South Wales, and Victoria.

And in 2016, The Snowy Mountains Hydroelectricity System/Scheme, whatever you want to call it, was added to the Australian National Heritage List.

So, whether you’re into skiing and snowboarding, hiking or camping, or you just want to check out the dams and power plants and other things related to these Snowy Mountains Hydro Scheme, the Snowy Mountains in the Australian Alps are definitely a beautiful spot worth checking out if you find yourself in the south east of Australia.
