For many years the Sonoran Desert was considered uninhabitable, but by exploiting nearby rivers and tapping into underground aquifers, cities like Tuscon and Phoenix have been able to thrive amongst the sands. By the late 1980s these reserves had become depleted and Arizona had to find a new way to meet the demand for water. In a four billion dollar engineering project, called the Central Arizona Project, they transported water from the Colorado River to prevent the cities from running dry.
