Overview of the Drought Status
Cape Town is heavily dependent on surface water which is contained within 6 major dams (Wemmershoek, Voelvlei, Steenbras, Theewaterskloof and Berg River Dams).
Below is a breakdown of the state of the Western Cape dams as of 10 March 2025
For the City of Cape Town Water Outlook click Water Outlook for 2024. For access to the interactive Dam Level Model, click here to download. For the Dam Level Model User Guide, click here. Although some dam levels are increasing with rainfall, the Western Cape is still at risk and therefore the South African Weather Service (SAWS) has recommended that drought measures continue for the foreseeable future. As such businesses need to plan for a new normal.

While many businesses are based in Cape Town, operations and supply chains may be located in other parts of the Western Cape. Thus it is critical for businesses to be aware of the water situation across the province.
