Dam levels
08 October 2026
The City of Cape Town and the National Department of Water and Sanitation measures dam levels to check how much water is available for the region and whether water restrictions are necessary for residents and businesses. The dam levels are critical for Cape Town’s water supply.
Daily levels
The dams in and around Cape Town form part of the Western Cape Water Supply
System, which is an integrated and collectively managed system of dams, pump
stations, pipelines, and tunnels. In addition to servicing Cape Town, the
system supplies water to towns in the Overberg, Boland, West Coast, and
Swartland areas, and provides irrigation water for agriculture.

Because each dam size is different, the best indicator of overall dam water levels is the total quantity stored expressed as a percentage of total dam capacity. This statistic is shown in the bottom line of the table.
