Put today's dam level, the restriction level or a water-saving tip on your website or blog. It's free, takes one line of code and updates itself. Prefer to build your own? The same figures are open as JSON.
<script src="https://www.waterdashboard.co.za/widget.js" data-variant="level" async></script>Theewaterskloof can hold more than half of all the water in the six dams (53%).
Each circle's size is how much the dam holds when full. The water inside covers the share of the circle the dam is full, so a half-full dam is half covered.
