Played golf out at Theewaterskloof yesterday. Although there are still lots of little islands poking up as well as the tops of shrubs and trees visible, it looks infinitely better than it did 5 or 6 months ago. If we can survive the Summer and get good rains again next Winter, it might end up close to full.

9.91 mm at Dwarsberg
New Tom Brown report available
I would never have thought, great! Looks like a few more mm on Monday :)

We had a very good OCT17 in terms of Dwarsberg mm, last few years before that have been as poor as we are having now.

I drove past Theewaterskloof dam yesterday... still looks incredibly low. Hella lot better than in March this year though when I was last there.

Its is a big dam with a large surface area
In other words, its a big shallow dam. Even when 80% full it still looks half-empty...

Will probably take another 2 years of good rain to fill.
Given that it takes 2 years to fill, Theewaterskloof is not really a dam, but an overflow reservoir for the Berg River Dam, which takes less than 6 months to fill in normal years.

There were mutterings that it should never have been built so large, because valuable farmland was taken out of production. In reality that last 20% of capacity is very rarely used, and evaporation is a huge issue. However, there is zero chance of the dam wall being lowered.

More rain on the way in the next few days. Meanwhile here in PTA, we have roads flooded low water bridges closed, subways flooded, and more than 60 mm of rain in less than an hour.
