Arizona v. California

Arizona v. California is a Supreme Court case addressing how water rights are allocated from the Colorado River. Arizona challenged California’s use of water ahead of its legal entitlements, arguing that California was taking more than its fair share under existing agreements. The case focused on interpreting water compacts and ensuring equitable distribution among states. In 1964, the Court ruled that Arizona was owed additional water from California based on prior agreements, emphasizing fair allocation and respecting states’ contractual rights to share the Colorado River’s limited water resources.
