Kuna tofauti kubwa sana ya DAM na Water Pan.
Ordinary Kenyans call even swamps dams.
Ruto anamaanisha 5 DAMS and 95 Water pans.
Nyandarua area has so many such water pans that were constructed by the Brits in the 1940s, 1950s but most of them have fallen to dereliction, if they were to do desilting it would save the tax payers huge revenues
