Granite Reef Diversion Dam: A Comprehensive Overview
The Granite Reef Diversion Dam, an engineering marvel located in the heart of the United States, stands as a testament to human ingenuity and the importance of water management. This article delves into the various aspects of the Granite Reef Diversion Dam, providing you with an in-depth understanding of its significance, construction, and impact on the surrounding environment.
Location and Purpose
The Granite Reef Diversion Dam is situated in the state of Arizona, United States. Its primary purpose is to divert water from the Salt River to the Central Arizona Project (CAP), a vast water conveyance system that supplies water to the Phoenix metropolitan area and other parts of the state.

Design and Construction
The Granite Reef Diversion Dam was designed by the Bureau of Reclamation, an agency within the United States Department of the Interior. Construction began in 1973 and was completed in 1977. The dam is a concrete gravity dam, which means it relies on its own weight to hold back water.
The dam is approximately 1,050 feet long and 200 feet high. It has a spillway that can handle a maximum discharge of 50,000 cubic feet per second. The design of the dam ensures that it can withstand the force of the water and maintain its structural integrity for many years to come.
Environmental Impact
The construction of the Granite Reef Diversion Dam had a significant impact on the surrounding environment. The dam altered the natural flow of the Salt River, which affected the local ecosystem. However, efforts have been made to mitigate these effects.
One of the most notable environmental initiatives is the Granite Reef National Wildlife Refuge, which was established to protect and restore the natural habitat of the area. The refuge provides a home for various species of birds, fish, and other wildlife, ensuring that the ecosystem can thrive despite the changes brought about by the dam.
Water Supply and Distribution
The Central Arizona Project, to which the Granite Reef Diversion Dam diverts water, is a crucial component of the state’s water supply. The project transports water from the Colorado River to the Phoenix metropolitan area and other parts of the state, providing a reliable source of water for millions of people.
The CAP system consists of more than 3,000 miles of canals, pipelines, and pumping stations. The water is transported through a combination of gravity and pumping, ensuring that it reaches its destination efficiently. The Granite Reef Diversion Dam plays a vital role in this process by diverting water from the Salt River to the CAP system.
Economic Impact
The Granite Reef Diversion Dam and the Central Arizona Project have had a significant economic impact on the state of Arizona. The project has created thousands of jobs during its construction and operation, and it continues to provide employment opportunities for many people.
In addition, the reliable water supply provided by the CAP has allowed for the development of agriculture, industry, and residential areas in the Phoenix metropolitan area and other parts of the state. This has contributed to the economic growth and stability of the region.
Conclusion
The Granite Reef Diversion Dam is a remarkable engineering achievement that has had a profound impact on the state of Arizona. Its construction and operation have provided a reliable water supply for millions of people, while also addressing the environmental and economic challenges of the region. As the state continues to grow, the Granite Reef Diversion Dam will remain an essential component of its water management strategy.
