What happened

While most were celebrating the overflowing local dams, the farmers of the Gamtoos Valley and residents of the lower Gamtoos were counting the costs of the damage caused by the devastating floods.

Why it matters

There is a lot of opinion on the whole scenario, but one thing is for sure, all should be happy that the local supply dams were at a low level before the flood water arrived.

Common ground

The Algoa System stood at a combined capacity of just 36% before the rains started on Tuesday, then rose to 106% by Thursday and 115% by Friday morning.

Perspective signals

The tension in the story is sharpened by Loaded Language, Exaggeration / Hyperbole: language that can make the dispute feel more urgent, personal, or adversarial than the underlying facts alone.
