One hundred years after leaders from seven Western states gathered to sign what was at the time a historic agreement, the Colorado River is once again at a breaking point. 

The federal government is now paying communities in California, Arizona and Nevada to avoid using water from the Colorado River, and hydropower production has fallen due to historically low levels in the nation’s largest dams.

This is leading some experts to advocate for making changes to the Colorado River Compact, which was signed on Nov. 24, 1922. 

Ahead of this anniversary, here’s a look at Colorado State University resources and water experts who can provide insight on the history of the compact, the state of water in the West and what’s next for the Colorado River.
