Theewaterskloof Dam—the linchpin of the region's municipal supply—has surged to 77.78% capacity standing in stark contrast to the 63.06% recorded this time last year.
Winter rains have delivered a massive boost to the Western Cape’s water security, pushing major supply systems to the brink of the critical 80% threshold and triggering a remarkable recovery for the province's largest reservoirs.
According to the latest data released by the Department of Water and Sanitation, the Cape Town Water Supply System rose to 77.63% capacity this week, a solid increase from last week's 76.94%. The broader provincial state of dams mirrored this positive momentum, climbing to 78.84% from 77.97% as catchments across the region continue to intercept consistent seasonal rainfall.
Leading the charge is the massive Theewaterskloof Dam—the linchpin of the region's municipal supply—has surged to 77.78% capacity, standing in stark contrast to the 63.06% recorded this time last year. Operational flexibility has been further bolstered by smaller, high-elevation reservoirs like Steenbras Upper, which are officially overflowing at 102.17%, and Wemmershoek, hovering on the knife-edge of spilling at 99.95%.
Meanwhile, the Olifants-Doorn catchment boasts a staggering turnaround; the Clanwilliam Dam now stands at 96.00%, more than doubling the dismal 41.42% recorded during the same week last year. Even the drought-stricken Garden Route is seeing relief, with Knysna’s Akkerkloof Dam climbing to 41% due to active pumping from its balancing systems.
