The Central Arizona Project and Its Infrastructure
The Central Arizona Project (CAP) plays a crucial role in transporting Colorado River water across the state, utilizing six pumps to lift water 800 feet and moving it through a 336-mile canal system. This infrastructure, designed to operate at a capacity of approximately 3,000 cubic feet per second, is essential for supporting agricultural fields and the state’s largest urban areas. Initially authorized in 1968, CAP took about 20 years to complete, enabling Arizona to harness its full allocation of river water as established by various legislation and negotiations. The development of this project was not only a significant engineering feat but also a critical response to the growing water demands of the population and agriculture in Arizona.
