Drought in the Southwest

Drought in the Southwest

Prolonged dry conditions are a natural part of life in the Southwest. Past records from tree-rings indicate that the Southwest has experienced protracted “mega” droughts that lasted about 50 years, a duration unlike the 1950s and 2000s droughts that caused economic losses to agriculture, ranching, industry and many other sectors. Because of recurring drought, many efforts have been made to minimize its impacts on human activity. The Colorado River, for example, stores about four years of water supply to buffer the affect of several consecutive years of below-average streamflows. However, some sectors are more vulnerable to drought than others, and drought can appear rapidly after just one season of below-average precipitation. Summer grasses, for example, that provides fodder for livestock do not grow in abundance or with as much health if the monsoon rains fizzle.
