Both in amending the routes to miss the very bad spots - as noted by a previous poster who lives in the area. And in noting the potential issues with the pont. SO much easier to plan route markers and staff allocation earlier. The pont is very much like Augrabies. It is impacted by weather a few hundred kilometers away. And once the catchment dams are full the resultant high water flow levels are inevitable. As a descendant from Swellendam I am VERY glad this event is going ahead !! The economical spin offs for the town and wider area is very good. DNC, JohanDiv, Danger Dassie and 3 others 5 1 Link to comment Share on other sites More sharing options...

We have more rain before Saturday in the overberg so the rivers will be flowing faster by Saturday Edited July 23 by DieselnDust JohanDiv and ChrisF 2 Link to comment Share on other sites More sharing options...

This statistic is shown in the bottom line of the table. Seems like its overflowing to me. This was data as per 22 July 2024 numbers. I like numbers. We do this weird thing here, in that we can overfill out dams so they go way beyond their capacity, TWK for instance can hit about 106% before it's actually overflowing. so ja, it's not actually sending the water to the breede in massive amounts, currently about 10% of flow at swellendam is from riviersondereind. 1 hour ago, JohanDiv said: A friend sent me a video of the overflow he took this morning.

There are effectively zero dams on the breede, all the irrigation schemes are weirs and canals. The floods come and a 10days later it's back to normal, but heavy rainfall in the catchment and then a 2-3 days lag max. Got nothing to with dams.

TWK max rate can vary but ya 106% sounds about right to be within the factor of safety for the dam wall structure. Point is filling a dam is not like filling a bath. Inflow is continuous basis the degree of ground water saturation in the catchment including mountains and water table. These are currently high so any additional rainfall will go straight to the dam and that is currently at maximum capacity so sluice gates will be open delivering continuous flow to the downstream rivers. The challenge with the Pontoon is the speed of flow . Its doesn’t much additional cumecs to make it unsafe to operate. Generally Swellendam has very predicatable weather patterns and it appears the organisers are linking in with the necessary safety and environmental agencies re the risk of the pontoon over the coming weekend basis the predicted rain fall in the WC.

FarmerMTB Posted July 23 Share Verskoon my taal, maar my Engels is op die oomblik net so vrot as wat my fiksheid is. Het vandag en afglope 3 dae groot dele van die 100miler se roete gery. Dit is soos roete op die oomblik lyk en kan baie verander indien ons reen kry en hy verander selfs agv daai manne wat in die geel lorries ry en so lekker op 'n graaf kan hang. Soos iemand reeds gese het het ons aansienlik minder reen hier in Swellendam gekry as die res van die Kaap. En dan het ons hier waar julle gaan ry, nog minder reen as in die dorp, onder die berg gekry, maar aangesien dit 'n nat jaar was tot hede, loop die fonteine nog sterk: party in die pad en ander oor die pad. Huidiglik is die pad droog. Die hoof grondpaaie, Napkei, Malgas, Platrug en Ouplaas-pad is drooi sonder modder-gate. Dis die kleiner paadjies wat die groot grond-paaie verbind is wat nat kolle het (en seker modder gaan word as jy deel is van die laaste fietse wat daar deur-gaan) Dis nie die hele pad nie, maar die fonteine gaan nie teen die naweek ophou loop nie, en 'n padskraper gaan ook nie iets daar kan doen nie. Let wel, dis net kolle op die verbindings-paaie. Soos ek gese het kan dinge vinnig verander, want hier loop reeds 'n padskraper en op 2 plekke het hulle die nat kontein-kol uitgegrawe om dit beter te maak. Ek dink die nuwe roete gaan jul 'n ander deel van die ruggens was, of soos ek altyd se: Die gat-kant van die wereld Geniet jul Race JohanDiv, Shebeen, Rowl and 7 others 5 5 Link to comment Share on other sites More sharing options...

Op die staduim 98% van die pad is droog. Die ander 2% is net nat, Tarentaal-(photo) baie water. Vryheid- water loop oor pad(Klein stroompie), Malanskraal- paar kolle in drif en waar oor werf gaan, Haarwegskloof-so 1km wat water in pad syfer. Tussen die nat-kolle trek die stof die stof. Dus as jy voor ry gaan jy bietjie nat word, as jy agter ry gaan jy vuil word. Die pad is 100% beter as 2022 se modder.

FarmerMTB Posted July 23 Share Had this great idee of handing out free beer as the bikes pass our farm, but the problem is you pass me at 58km... Don't think anyone will want a beer at 10'Oclock in the morning with 11*C temperatures!!! Link to comment Share on other sites More sharing options...

mrcg Posted July 23 Share Weather is looking ok in terms of rainfall, however currently the forecast is for strong gusty winds from about 11am. Which means either lekker tailwind or side-on / head-on. Good luck riders Link to comment Share on other sites More sharing options...

There was a renegade waterpoint at about 35km giving out witblitz shots in the rainy/muddy 2022 event. that lit the fire for sure!
