What was allocated to Arizona per the 1963 U.S. Supreme Court ruling regarding Colorado River water?

The 1963 U.S. Supreme Court ruling regarding the allocation of Colorado River water established a specific apportionment of water among the states that share the river's resources. Arizona was allocated a significant portion to ensure its water supply for agricultural, urban, and industrial uses. The court determined that Arizona should receive 2.8 million acre-feet of Colorado River water annually. This allocation was crucial for Arizona's growth and development, enabling the state to secure a reliable water source to meet its expanding needs. Understanding this allocation is key to grasping the complexities of water rights and entitlements in the arid Southwest, where competition for water resources remains a pivotal issue.
