Not quite what you are describing, but there are a series of vleis and wetlands in the area, in this case visible from Ou Kaapse Weg lookout:

Yes, the same view, but showed all the vleis as one big lake, very few houses so I presume it was from the 1800's

Still hunting it out

I assume all 5 dams on Table Mountain will be overflowing after this. Would be worth the hike up to go check it out. The Hely-Hutchinson and De Villiers overflows is usually spectacular

There is a video of one of the main waterwalls/rivers being blown upwards by the strong winds yesterday.

I am old, but I wasn't alive in the 1800s...

In 100 years time most of the Cape Flats will be underwater, due to sea level rise...

Keep going. We need to fill those dams.

That is not a small amount of water...

Edit: Given it's capacity, that is an amount of 25 million m^3 of water, at an inflow rate of 300m^/sec for 24 hours! The 'consumption' rate of 1 million m^3/sec was exceeded by a factor of 25:1 during that period...

The SAWS reports widespread heavy rain over much of the SW-Cape during the 24 hours to 8am on Wed 10th: https://www.weathersa.co.za/images/data/climate/nr_daily_rai.pdf
Highest include Villiersdorp 101mm, Franschhoek 94mm, Kirstenbosch 76mm, Paarl 61mm, Ceres 59mm, Wellington 57mm, etc. Areas away from the mountains received somewhat less rain.

The 10 day update (tomorrow) will make for interesting reading.

And Theewaterskloof is mainly meant to capture snow melt, so I foresee a lot more inflows.
 
People in Newtown Wellington were asked to evacuate apparently. There's a dam wall that's seemingly about to collapse.

Muizenberg circa 1950 - see the flats were just sand dunes and seasonal vleis - maybe this is even before they brought in port jackson and rooikrans to stabilize the sand.
 
I see a few of my colleagues have received notices from their respective schools that the Dept of Education has shut all schools in the Metropole tomorrow. They must be expecting some bad weather then!

My kids school just let us know as well, schools closed.

I don't see specific things in the forecast that would make them close schools tomorrow (Thurs 11th). Maybe just being cautious, and worried about cumulative flooding and wind damage. Or catching up on the 'missed' warnings on Tues 9th?

Yeah seems overrated. Alas, we live in a time of weak men.
