Boland Mountains
DID YOU KNOW?

The Boland Mountains provide 97% of Cape Town's water supply.

The big six dams that supply the city with water are all in or very close to this water source area. The Breede River, the largest river in the Western Cape, and a key resource for economic activities in the region, flows out of the area.

It loses 4.1% of its water to invasive alien trees and, were it not for previous alien clearing, Cape Town may well have hit Day Zero during the recent drought crisis.
