The Central Arizona Project Canal is a crucial infrastructure that supplies water to 80% of Arizona's population. It redirects water from the Colorado River, impacting urban and agricultural development. Despite its design, the canal inadvertently acts as a water harvesting structure, creating microclimates and supporting native vegetation. This highlights the ecological benefits and challenges of such infrastructure in desert environments.
