As negotiations over the Colorado River's water allocation continue, Arizona tribes like the Gila River Indian Community are facing the prospect of significant reductions in their annual water supply. The tribe has implemented conservation measures like solar panels over canals and automated irrigation systems, but could still lose up to half of the water it has received in recent years.

Why it matters

The Colorado River is a vital water source for millions across the Southwest, and any reductions in allocation will have major impacts on communities that rely on this resource. Arizona tribes like the Gila River Indian Community have long-standing water rights, and cuts to their share could threaten their agricultural operations, economic development, and overall way of life.

The details

The Gila River Indian Community has taken proactive steps to conserve water, including installing solar panels over canals to reduce evaporation and implementing automated irrigation systems. However, the tribe could still lose up to 50% of the water it has received annually as part of the ongoing Colorado River negotiations between states, tribes, and the federal government.

• The Colorado River negotiations have been ongoing for years as states and tribes work to determine water allocation amid drought conditions.
• The Gila River Indian Community has received a specific annual water allocation from the Colorado River for many years.

What’s next

The ongoing Colorado River negotiations will determine the final water allocation for the Gila River Indian Community and other tribes in the region. A decision is expected by the end of 2026.
