There are many ways that a drought can be defined. A dictionary definition is simply an "absence of moisture" or "prolonged dry weather." Another common approach is to relate a drought to times when the demand for water exceeds the available supply of water. When there are widespread shortages, or projections of shortages, it becomes quite apparent that a drought is occurring. At other times, if most demands are being satisfied, it may be difficult to say we are in a drought. In Colorado and other arid western states, a drought may affect farmers, cities, and other water users differently depending on the severity of the drought and the water supplies owned or available for their use.
