In mountainous districts, lakes or man-made reservoirs are used to furnish a good head of water to generate hydro-electric power. Natural lakes are preferred to artificial reservoirs because the volume of water that flows from them varies very little throughout the year. For instance, the Niagara River flowing from Lake Erie to Lake Ontario has a very regular supply of water for its power stations, whereas the Catawba River in the Carolinas which does not flow from a lake, has very little water during dry season. Cotton mills have been forced to close down during the period of drought due to insufficient power supplies to run the mills. The Lloyd Barrage on the Indus at Sukkur suffer from similar defects. The Abu Bakar Dam of the Cameron Highlands supplies much hydro-electricity for central West Malaysia.
