Decoding the Colorado River Compact: 5 Arizona Water Projects Affected by the Agreement

The Colorado River Compact, signed in 1922, has had a profound impact on Arizona's growth, water rights, and major projects like the Central Arizona Project (CAP). This agreement, which involves seven states including Arizona, Nevada, Utah, New Mexico, Wyoming, Colorado, and California, governs the use of the Colorado River's waters. Understanding how this compact affects Arizona's water supply is crucial for outdoor enthusiasts and travelers alike.

Water Storage Projects

The CAP, a 336-mile canal system that brings water from the Colorado River to central Arizona, is one of the most significant projects affected by the Colorado River Compact. Other notable water storage projects include:

• Lake Mead: The largest reservoir in the United States, Lake Mead is a vital water storage facility that supplies water to Arizona and other downstream states.
• Lake Powell: A massive reservoir created by the construction of the Glen Canyon Dam, Lake Powell is a popular destination for boating and fishing.

Irrigation Projects

The Colorado River Compact has also impacted irrigation projects in Arizona. The CAP canal system supplies water to agricultural areas in central Arizona, while other projects like the Salt-Gila Aqueduct provide water to cities like Phoenix and Tucson.

• Central Arizona Project Canal: This 336-mile canal system brings water from Lake Havasu to central Arizona.
• Salt-Gila Aqueduct: A major irrigation project that supplies water to cities along the Salt River.

Water Treatment Plants

The Colorado River Compact has influenced the development of water treatment plants in Arizona. These facilities are essential for purifying and distributing water to meet the needs of growing populations.

• Phoenix Water Treatment Plant: This facility, located near downtown Phoenix, treats water from the CAP canal system.
• Tucson Water Treatment Plant: Located on the Santa Cruz River, this plant supplies treated water to Tucson residents.

Hydroelectric Power

The Colorado River Compact has also affected hydroelectric power generation in Arizona. The Glen Canyon Dam and other dams along the Colorado River produce electricity for Arizona and other downstream states.

• Glen Canyon Dam: This massive dam produces over 3,000 megawatts of electricity and stores water in Lake Powell.
• Davis Dam: Located on the Colorado River near Laughlin, Nevada, this dam generates hydroelectric power for Arizona and California.

What to Expect

Visitors to Arizona can expect stunning natural beauty, rich cultural heritage, and diverse outdoor recreation opportunities. When planning a trip to these water projects, consider the following:

• Best Time to Visit: Spring and fall are ideal times to visit Arizona's water storage projects, as temperatures are mild and wildflowers are in bloom.
• Accessibility: Many of these projects have public access roads and viewpoints, while others require hiking or boating to reach.

Practical Info

• Check with the U.S. Bureau of Reclamation for up-to-date information on water levels and recreation opportunities at Lake Mead and Lake Powell.
• Contact the CAP agency for more information on irrigation projects and water treatment plants in central Arizona.
• Visit the Glen Canyon Dam website for details on hydroelectric power generation and tour schedules.
