My dad was a civil engineer and in the early 1960's he did the survey work for the PK le Roux Dam, which l think was renamed VanderKloof. Thanks for your interesting and informative work always. I still have my grandfather's planimitre, an instrument for measuring on a map the catchment area of a river at a specific point. The people who designed the dam must have known how much water to design for for a 1000-year flood, knowing that such a thing would happen.
Thanks Jors for the "dam" fine video and "dam" interesting facts and figures. You create such interest, that it makes us all want to travel to these places ourselves. Thanks for sharing your interests and passions and promoting our lovely country! ❤😊🙏
Hey Jors! thanks for this. I also find these huge constructions quite fascinating. Those 'bollards' in the spillway create a break in the water curtain which allows air to get sucked in behind the water curtain preventing a vacuum build-up. In their absence the vacuum behind the curtain would pull it back to the wall as the air would all have to come from the sides of the curtain. Because the water is trying to follow its natural trajectory, the curtain can break allowing air straight in but only in 'gulps' so to speak. As a result the curtain starts fluctuating away from and back to the wall. Given the tonnage involved the water curtain starts hammering the wall and can cause damage. It may be that in the history of dam building this actually happened and someone was able to figure out what was happening. The phenomenon is well known among dam designers.👍
Thank you for this very interesting video. It amazing how well built the dam walls were back in the day, strong foundations & workmanship! Nice to see your wife with you. Look forward to the next one! Have a good 2nd week of 2024. Cheers from PE
Hello Jors, happy new year to you and your family for 2024. Thanks so much for sharing. Really appreciate and enjoy your video coverage and your knowledge sharing of the dams and rivers. Your photography and explanations are exceptional! In mid January 2022 I took my family to see Gariep and Vanderkloof dams overflowing, as well as Augrabies Falls in flood. It was an exhilarating once in a lifetime experience for most of my family. I will try again to do the same one day if the opportunity presents itself. The enormous power of the water as it flows over those huge dam walls is a sight to behold. We can be so proud to have these structures as part of South Africas 'water' infrastructure! Enjoy and safe travels. Cheers.
Die water is pragtig - baie dankie! Praat van babers - hoe groot kan 'n baber word? Ek het vissermanstories gehoor dat die babers teen die damwal (binne-in die dam) so groot word dat hy 'n man kan sluk. Waar, of visserman se storie?
Goeie more Jors, dit was 'n baie pragtige video. Amper meer mooi op kamera as om self te kuier by die dam. Die ingenieurs werk is natuurlik van die hoogste kwaliteit! Die natuurskoon rondom die dam is net so mooi, alles meltsaam op 'n besonderse manier. Die visse was interessant. So die water is ook 'n baie goeie kwaliteit dit spreek vanself. Baie dankie dat ons kon sien hoe goed die watervlak en vloei van die rivier is. Hoop julle het veilig gery voordat die storm gebreuk het want partykeer is daat meer water in die wolke as wat 'n mens dink. Mooi loop.
Wow, simply love it ! I know Eskom does the maintenance on the generation side of things, how good is the maintenance on the water input and output side by Water Affairs. ? So glad you did a dam visit or two for us on presumably your New Years breakaway. Enjoy and relax !
Dankie Jors, Indrukwekkende struktuur. In een vd skote rivier-af is daar n bree groen strook ontboste area. Dit is seker onder die kraglyn? Selfs as dit is, lyk dit "onnodig" wyd? Miskien uit oormaat van versigtigheid as daar n brand sou wees?
Hi Lanie, ek het hom gister aand opgesit en daar was fout met die klank, ek het daai een toe private gemaak en hom weer opgelaai met regte klank vanoggend.
Net 'n ope vraag aan iemand wat weet: Word daar gereeld onderhoud/ toetse gedoen op die nood sluise om te kyk of dit nog werk? Ek weet van kleiner damme onder munisipale beheer waar daar dam sluise is wat glad nie meer werk nie agv 'n gebrek aan onderhoud
EK het Gariep dam se sluise al oop gesien tydens vloed, ek kan nie onthou of dit 1988 was of later nie. Of hulle dit gereelds toets is ek nie seker nie, maar die ontwerp van die sluise is van so aard dat minimale onderhoud nodig is. Ek weet dat daar op Kouga dam wel onlangs onderhoud aan sluise gedoen is , seels wat gelek het is vervang.
Baie mense is onder die indruk dat daardie noodsluise die kragstasie is ,ek het al by Gariep gestaan en luister hoe hulle aangaan omdat die turbines dan nou nie loop nie😂😂😂
Was taught as a child, no crocs in our rivers flowing towards the West, only in those flowing towards the East. Seems to hold true as a general baseline.

The original name was indeed PK le Roux. Thanks for the information, that is cool.

As always, a very informative clip. Thank you.

Of course, back in the day, we had proper qualified engineers and construction companies. Unlike the current rabble.
Dankie Jors! Altyd goeie aanbieding en uiteensetting. 👏👌
Dankie Jors dat jy Vanderkloof damwal besoek...en geniet. Ek was destyds stadsklerk daar, van 1980 tot 87.
Môre Jors 🌞 baie dankie dat julle ons saam vat op julle familie roadtrip. Groete vir jou en jou hartsmense 🙏🌻
Dankie Jors, baie interessant, wonderlike wolke daar!

I agree, seeing the watet flowing first hand is an incredible experience.
I was lucky enough to see the Gariep in Dec 21 and the Van der Kloof Dec 22 in full spillway overflow.
Geniet die inligting en wou nog altyd die dam besoek en nou het ek baie dankie
Very interesting thanks Jors
This dam has very pleasing lines.
Thanks Jors, very interesting. Enjoy the week ahead.
Ke ya LEBOHA,My Broer. A Beautiful Engineering. masterpiece
Good Evening 😊 Thanks for sharing 👍🏼 Awesome dam👌🏽 God bless 🙏🏽 Greetings from Limpopo Province
Dankie Jors , goeie werk

Always so informative,love your videos 👍👍
Dankie waardeer jou updates
Incredibly impressive. Has to be one of the largest dams surely.
It is the second largest in South Africa tomorrow we visit the largest, Gariep dam.
Dankie Jors,
Indrukwekkende struktuur.
In een vd skote rivier-af is daar n bree groen strook ontboste area.
Dit is seker onder die kraglyn?
Selfs as dit is, lyk dit "onnodig" wyd? Miskien uit oormaat van
versigtigheid as daar n brand sou wees?
Die verskil in water kwalityd tussen Gariep en Vanderkloof is merkbaar...
Waar kan mens kamp daar en visvang ?
We should fish from the bridge jors
Going to Groblershoop towards the end of the month and afraid I might not be able to fly fish😪
Môre Jors 🌞 ek het nou ń kennisgewing gesien van ń nuwe video. Ek het geklik toe wys dit “this video is private”?
Hi Lanie, ek het hom gister aand opgesit en daar was fout met die klank, ek het daai een toe private gemaak en hom weer opgelaai met regte klank vanoggend.
Nou waarom is die naam van PK Le Roux verander na Vanderkloof?
Vir dieselfde rede as wat die Verwoerddam nou Gariepdam heet. As sy naam Prince Charles was het jul hom natuurlik dood stil gelos.
😎
Net 'n ope vraag aan iemand wat weet:
Word daar gereeld onderhoud/ toetse gedoen op die nood sluise om te kyk of dit nog werk?

Bly maar mooooooi
Quick silly question but are there crocs in the Orange river?
There are no crocodiles or hippos in the Orange River
Unless you are having trouble getting your children out of the water, then there are lots…
Rhere are no crocs in the Orange river.
Was taught as a child, no crocs in our rivers flowing towards the West, only in those flowing towards the East. Seems to hold true as a general baseline.
