Western Cape dam levels fell marginally in the week ending 23 August 2026, with provincial storage dropping from 80.28% to 80.12% and the Cape Town Water Supply System declining from 77.87% to 77.26%. Theewaterskloof Dam, the largest in the system, stood at 77.56%, according to Department of Water and Sanitation figures reported by News24 on 19 August.
Provincial water officials say restrictions are not imminent, but the City of Cape Town has warned that the risk has risen compared with previous years. A live dam tracker on 24 August showed provincial dams averaging 79.9%, down 0.3 points on the week and 4.2 points lower than the same week in 2025.
"We are not anticipating water restrictions for now," Ntombizanele Bila-Mupariwa, provincial head of the Department of Water and Sanitation, told News24 on 19 August. "However, should any municipality see that they are heading for a period when they need to implement restrictions, they can do so."
The City of Cape Town issued a statement on 7 August when dam levels were at 78.1%, urging residents to conserve water through the coming summer. "The City’s latest 2026 Water Outlook does not indicate an immediate risk to water supply, but the risk of restrictions has increased compared with previous years," the statement said.
Cape Town’s water security remains sensitive nearly a decade after the 2015–2018 drought that pushed the metropole to the brink of "Day Zero", when Theewaterskloof fell below 20% capacity. Current levels are far healthier than the crisis years, but the year-on-year decline and below-average winter rainfall have prompted officials to prepare contingency plans.
Bila-Mupariwa told SABC News on 23 August that the province was monitoring dam levels closely. "The minute we see that it is going to reach a percentage where we have to start the water restrictions, we are definitely going to do so," she said.
No Western Cape municipality has yet announced restrictions, and the provincial government has not declared a drought disaster. The City has asked residents to reduce consumption as rainfall tapers off and evaporation increases through the spring and summer months.
It remains unclear whether below-average rainfall will persist into the spring, and no municipality has indicated a date for potential restriction announcements. Cape Flats will check the next weekly dam-level update from the Department of Water and Sanitation on 31 August.
