This resource focuses on the crisis facing the Colorado River Basin, which supplies water to over 40 million people across multiple states and Mexico. It emphasizes the impact of a prolonged megadrought, the decline of Lake Mead's water levels, and the implications for regional economies and urban stability. Additionally, it explores the dependency of Phoenix, Arizona on advanced irrigation infrastructure and the challenges it faces as water sources dwindle. Through analysis exercises including observation, inference, and questioning, students are tasked with drawing parallels between historical water dependency and modern urban resource challenges, as well as predicting future migration patterns influenced by water scarcity.
