Western Cape dams continue steady recovery: LATEST figures

· The South African

Cape Town’s major dams continue to show healthy recovery levels, with overall storage reaching 72.9% this week as winter rainfall steadily replenishes the city’s water supply system.

According to the latest dam level report released on Tuesday, 9 June, the six major dams supplying the Cape Town metro are collectively storing 654 618 megalitres of water out of a total capacity of 898 221 megalitres.

Well ahead of 2025

The latest figures show a slight increase from the previous week’s overall storage level of 72.4%, while remaining well ahead of the 62.9% recorded at the same time last year.

The largest dam in the system, the Theewaterskloof Dam, is currently 74.5% full, up from 61.8% during the corresponding period in 2025.

The Berg River Dam is sitting at 76.9%, while Voëlvlei Dam is at 59.3%.

Among the strongest performers is Wemmershoek Dam, which has reached 97.9% capacity, compared to just 57.8% at the same stage last year.

The Steenbras Upper Dam stands at 82.3%, while the Steenbras Lower Dam is currently 48.7% full.

Three-quarters full in total

The city noted that because each dam varies significantly in size, the most accurate measure of available water is the total quantity stored across the system as a percentage of overall capacity.

On that basis, the metro’s dams are now holding nearly three-quarters of their combined storage capacity.

Recent rainfall across the Western Cape has contributed to gradual increases in several of the province’s key water supply dams, with overall storage levels continuing to track well above those recorded a year ago.

While dam levels remain healthy, authorities continue to encourage responsible water use as the winter rainfall season progresses.
