State, federal and tribal leaders met in Boulder, Colorado to talk about the Colorado River's next chapter. They don't appear close to an agreement.

Some experts say the System Conservation Pilot Program is costly and may not be the most effective way to save Colorado River water.

The tribe has one of the largest single outstanding claims in the Colorado River basin, and Thursday's vote marks one of many approvals needed to finalize a deal that has been years in the making.

A proposed water rights settlement for three Native American tribes in Arizona has taken a significant step forward with an introduction in the Navajo Nation Council. It's the first of many approvals needed to finalize a deal decades in the making.

A company spun out of NASA’s Jet Propulsion Laboratory began survey flights over the Uinta Mountains this year. Water managers are already using the data to manage Colorado River water wisely.

Eighteen tribes that use Colorado River water sent a list of principles to the federal government as contentious talks about how to share the shrinking supply continue.

“This kind of money is huge for southern Utah,” said Republican Rep. Celeste Maloy. “It's hard to overstate how high the stakes are.”

Arizona's Gila River Indian Tribe said it does not support the Lower Basin's proposal for post-2026 river management, adding a new layer to the complicated negotiations.
