The Colorado River Basin's Millennium Drought The Colorado River Basin's Millennium Drought
Is the Colorado River Basin in a drought or is it aridifying? The Colorado River Basin is no stranger to drought. However, not all droughts are the same. It is important to know whether the current drought is actually the first stages of aridification, because planning for and managing a drought is different than aridification.
