In a few weeks, the Supreme Court will hear arguments in Tarrant Regional Water District v. Herrmann, an Oklahoma-Texas water case that experts say could have ripple effects on water-sharing agreements throughout the country.

It’s a complicated case, filled with disputes over geography, compact language, and questions of sovereignty. The stakes are high because water is increasingly precious, and states are getting serious about protecting a resource that’s key to economic progress.

The Tarrant water case is deep, but StateImpact wants to be your Red River guide. We’ve assembled a visual map to help you wade through the key components of this important Supreme Court case.
