South Africa dam levels.
This site is built around Cape Town. We track the six dams of the Western Cape Water Supply System (WCWSS) every day, run a Day Zero scenario predictor against them, and write up the local water-supply story in depth. For the rest of South Africa we don't carry our own data — the most reliable picture comes from the Department of Water and Sanitation.
The Western Cape dams supply Cape Town and the surrounding Boland and Overberg towns. Six dams hold the water — Theewaterskloof, Voëlvlei, Berg River, Wemmershoek and the two Steenbras dams. The Western Cape page has the per-dam breakdown.
Where to look outside the Cape.
National dam data is published weekly by the Department of Water and Sanitation. The hydrology section of the DWS website is where the news outlets pull their numbers from. There isn't a single one-page dashboard for every dam in the country, but the links below cover most of what's published.
