Western states that have been brawling over the drought-stricken Colorado River have finally found something they can agree on: a shared hatred of the Trump administration’s plans for managing the waterway.

But states, farm districts, cities, tribes and other major players on Monday unabashedly laid into the options the Bureau of Reclamation has laid out for doing so.

The comments — part of a draft environmental review process — are a last-ditch effort to influence Interior’s approach to a problem that affects the water supply for 40 million people from Denver to Phoenix to Los Angeles. They are also a first big step in laying the groundwork for the high-stakes Supreme Court battle that looks increasingly likely to ensue.
