Decoding the Colorado River Compact's Impact on Arizona's Water Supply

The Colorado River Compact, signed in 1922 by seven states including Arizona, has had a profound impact on the state's growth, water rights, and major projects like the Central Arizona Project (CAP). Understanding this complex formula is essential for outdoor enthusiasts, travelers, and residents alike to appreciate Arizona's unique landscape and navigate its water-rich heritage.

The Colorado River Compact allocates 7.5 million acre-feet of water among the seven states, with Arizona receiving approximately 2.8 million acre-feet per year. This allocation is divided between agricultural, industrial, and municipal use, affecting various regions in Arizona, including the Central Valley and the Phoenix metropolitan area.

The compact's formula has been subject to interpretation over the years, leading to disputes and controversies. The 1968 Colorado River Basin Project Act amended the original agreement, allowing for additional water storage and distribution projects. Today, these modifications continue to shape Arizona's water management policies.

To better comprehend the complexities of the Colorado River Compact, consider the following key points:

• Water Rights: Arizona has a priority date of 1907, giving it first claim to the river's waters.
• Allocations: The state receives approximately 2.8 million acre-feet per year, divided among various users.
• Projects: Major projects like the CAP and Lake Powell have significantly impacted water distribution.
