Cape Town – The recent rainfall in Cape Town is not enough to beat the drought affecting the city, Weather SA said on Friday."The rain does not make a difference to dam levels, because it is just too little. Dams with such a large capacity need at least 100mm of rain to see a difference in water levels," forecaster Stella Nake said.The city has received 24.4mm of rain in the past 24 hours. In Villiersdorp, where Cape Town’s Theewaterskloof dam is situated, 32.4mm of rain fell. Stellenbosch received 39.4mm of rain.
