The U.S. Supreme Court has approved a settlement ending the long-running dispute over Rio Grande water allocations among Texas, New Mexico, and Colorado, with the United States also participating in the case. The decree resolves one of the Court’s highest-profile original-jurisdiction water fights and establishes the framework for how water deliveries from New Mexico to Texas will be handled going forward.

The litigation centered on the Rio Grande Compact, an interstate agreement governing allocation of river water.
