One of the many highlights of Lesotho is a visit to Katse Dam, centrepiece of the Lesotho Highlands Water Project which channels the water of the Lesotho Highlands via an incredible series of dams and tunnels through the mountains eventually coming out of the Ash River Outfall near the town of Clarens in South Africa’s Free State province where it gravity feeds to supply Johannesburg and Pretoria with water.
It was touted as the greatest engineering project in the southern hemisphere in the 1990’s when it was under construction. Nowadays the sight of the massive dam hemmed in by the mountain valley is well worth beholding!
