On the big-picture side The Lesotho Highlands Water Project (LHWP) is a massive Government program resulting from a treaty signed in 1986 which was an agreement to sell water from the Lesotho mountain areas to South Africa. Visit their website at http://www.lhwa.org for project details. In addition to financial and hydroelectric power benefits the LHWP has been instrumental in the formation of the beautiful Ts’ehlanyane National Park. From the LHWP website:
For visitors, there is an information centre, which features a model of the whole project, showing all the phases. You can also go on a tour of the dam wall which is arranged by the Lesotho Highlands Development Authority Visitor Centre. The Katse Botanical Gardens is an added attraction.
The Katse Fish Farm project was born, working with nature in the pristine waters of the Kaste Lake in the Highlands of Lesotho. The Katse Fish Farm project (the only commercial fish farm in Lesotho) is currently producing 300 tons of trout per year.
