@simonkabs,
what do you mean 'only one major dam since 1940'?
Facts are:
1968 - Kindaruma
1974 - Kamburu
1978 - Gitaru
1981 - Masinga (perhaps this is one you are recognising)
1991 - Turkwel (many claim that this one is a 'White Elephant',yet when you look at the generation figures,Turkwel is the most reliable of all the hydros!! It's only problem was the inflated cost)
2008/9 - Sondu/Miriu
Behind the gardens...Behind the wall...Under the tree (Including: Red...Dark Blue...Yellow)
Nothing is real unless it can be named; nothing has value unless it can be sold; money is worthless unless you spend it.
