Hi Toko,

Thanks for the extra information. Basically the whole scheme will be run in the park boundaries then and referring to Riemvasmaak kind of softens the idea. SANParks surely was involved in the agreement if it is in the park and strange only now to come forward with a survey and this late stage. The impact of this project on the falls will depend on the volume of water required to run the turbines unless the intention of the weir is to route the water to the upper streams seen in the map below. So it is very difficult to say what will happen without getting honest answers to the concerns raised. South Africa needs more energy and currently don't make enough use of clean energy for the generation of electricity, which makes this project attractive. It will however be very wrong to loose one of our natural heritage to achieve this goal. Did they give any answers on the possibility of the river drying completely after the weir and over the falls during dry seasons? 0-

@ Lisbeth:
Water is diverted from the river at the diversion weir and returned to the river through the tailrace. This leaves the intervening stretch of river with reduced flow, which has impacts on the environment and also on the water flow for the waterfall.
The construction works over 3 years will be the biggest impact.

Several hydropower and solar plants are already on the cards in the Northern Cape, hence the question if the additional 20 MW in a protected area are really required :-?

The plan is to let 30 m3/s flow through the southern arm of the river (which is obviuosly the usual flow in winter now) through to the Falls. The off-take would be a maximum of 37m3/s, provided there is "surplus" water.

So the falls and the main arm of the river won't be completely dry \O

Ja, I was talking about the construction jobs (And satellite benefits)

There are plenty of weirs in the river in that area...floods just go over them. Once again, our last drought was maybe 1997? -O-

That's another question.

So it will be only power lines to photoshop out from a landscape pic of the falls. lol lol lol

Orange River hydropower station may commence in 2016
16 Jul 2015 02:57 PM



Bids for construction of the proposed hydropower station on the Orange River on the farm Riemvasmaak north of the Augrabies Falls are due to be submitted by October.

HydroSA said if its bid was successful, construction would begin in August 2016 and take 36 months.

The hydropower station will extract water 1.5km upstream of the Augrabies Falls, returning the water 7.5km downstream of the Falls. This will generate up to 40MW of electricity.

SANParks previously expressed its concern over its effect on tourism caused by the visual impact the station as well as on visitors’ experience of the Falls.

SANParks has also expressed concerns over the negative effect on the Augrabies Falls, as a sizeable portion of the river would be used. “A minimum reserve flow is required to maintain ecosystem integrity, especially as the choice of the availability of electricity to consumers is likely to supersede the volume of water flowing towards the Falls because the provision of electricity will be regarded as a priority,” said Nadia Lemmetuis, Regional Communication Manager for SANParks.

While SANParks supports renewable energy generated by technologies such as hydro, wind, solar and biogas, the organisation does not support the construction of the weir, canal and portion of the power line within Augrabies Falls. This is because the area through which the canal is planned is a ‘highly protected zone’ and categorised as a special management area. SANParks is seeking to reach an agreement with the National Environmental Management over the Protected Areas Act, 2003.

HydroSA also completed construction on the Kakamas hydro-electric power station in Neusberg, in the Eastern Cape, in January.

Augrabies nat, park under threat.

Post by H. erectus »

It is quite understandable that national parks are becoming more and more
threatened by population increase. The world becoming a awful small place
for all and wildlife to eek out existence,...

The few remaining pure wilderness situations bearing the brunt for that is
where often the answer lies in mans greed to eek a living,.. At that point
which would be more important, Human life,...or animal existence,...

With permission, Gerhard Smit, article published, SA Tourism update,.....


Much is being made of job creation and the need for electricity in our country, I realise this however not at the cost of destruction while other alternatives are readily available.

My wife and I have been visiting our National Parks regularly since 1967, Augrabies is one of our wonders which has been carefully conserved and preserved by our National Parks authorities for many decades. Now a Hydro- Electric power generating facility is planned for construction in the Orange (Gariep) River a few kilometres upstream from the Augrabies National Park.

Few sights are as awesome or a sound as deafening as water thundering down the 56m Augrabies Waterfall when the Orange River is in full flood. The Khoi people called it ‘Aukoerebis’, or place of Great Noise, as this powerful flow of water is unleashed from rocky surroundings characterised by the 18km abyss of the Orange River Gorge.

Picturesque names such as Moon Rock, Ararat and Echo Corner are descriptive of this rocky region. Klipspringer and kokerboom (quiver trees) stand in stark silhouette against the African sky, silent sentinels in a strangely unique environment where only those that are able to adapt ultimately survive. The 55 383 hectares on both the northern and southern sides of the Orange River provide sanctuary to a diversity of species, from the very smallest succulents, birds and reptiles to Hartmann's mountain zebra, springbok, gemsbok and giraffe.

The >60 000 visitors to Augrabies (12.2% of visitors to our National Parks) per annum do not visit the park because it is there, they visit to experience and enjoy this wonders of a waterfall in an arid area. Augrabies is the sixth most visited National Park in the RSA.

The Orange River does not have a consistent high volume flow of water, it is dependent on rainfall upstream. In high rainfall seasons the falls are spectacular, during poorer periods flow is often reduced to not much more of a trickle over the falls.

Much is said in the EA documentation about the flow not being less than the required minimum for the flow through the Augrabies National Park. We all are well aware that our environment does not mean much when money is at stake. Wonderful EMP’s can be drawn up, but when the river flow diminishes sufficient mitigation will be improvised to use whatever is left in the river to keep the power station operational, why: because the people have gotten used to the electricity and now it cannot be cut. We are experiencing power outages now especially in winter also the drier months, the Northern Cape and the Orange River will not be spared.

There are much less harmful alternatives available, the Northern Cape is well known for having the most cloudless days with good sunshine per annum, and therefor solar energy could offer a guaranteed supply of non-destructive green energy for the inhabitants of the surrounding areas.

Wind energy is another source of non-destructive energy.

A Hydro Electric power station above the Augrabies National Park in the Orange River, will spell the end to one of our esteemed National Parks and also to the surrounding tourist industry.

Persons who also care for the environment and especially the arid Northern Cape are requested to register as Interested and Affected Parties (I&AP’s) with Shawn Johnston at email address: swjohnston@mweb.co.za and lodge their objections which will form part of the public participation process. Unfortunately time is running out.

Our Department of Environmental Affairs and our Government will now have the grand opportunity to prove to the RSA citizens and the world that they really care by not approving this project.
