Dam levels

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.

**Current Dam Water Levels - 7/8/2026**
Major dams	Storage
Major dams	Ml	%
	Capacity when full	7/8/2026
Berg River	130 010	90.9
Steenbras Lower	33 517	53.6
Steenbras Upper	31 767	93.2
Theewaterskloof	480 188	77.8
Voëlvlei	164 095	61.5
Wemmershoek	58 644	98.6
Total Stored Ml	898 221	698 139
% Storage		77.7

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.
