A modest Colorado River proposal

A group* of my Colorado River collaborators has put together what we hope can be a useful set of foundational principles as the basin states and federal leadership search for a path toward a negotiated agreement for post-2026 Colorado River management. They’re based on a number of key premises: The Colorado River Compact will remain …

But, he continued, “that’s highly unlikely.” Via Anastasia Hufham in the Salt …
