In a pivotal Supreme Court session on March 20, 2024, the justices delved into the complexities of the ongoing water rights dispute between Texas, New Mexico, and the federal government. The case, Texas v. New Mexico and Colorado, centers on the interpretation of the Rio Grande Compact, which allocates water resources between the two states.

As the courtroom buzzed with anticipation, the discussions revealed deep-seated tensions regarding the management of water resources, particularly the D2 baseline, a critical measure established in the 1980s. The justices scrutinized whether adopting a modified D2 equation would fundamentally alter the operations of water management projects, such as the Elephant Butte Reservoir. This modification could impact how water is released and managed, raising concerns about long-standing agreements with downstream districts.

Justice Alito raised a crucial point about Texas's previous claims and the potential abandonment of those claims mid-litigation. The dialogue highlighted the federal government's role, with some justices expressing apprehension that allowing federal intervention could expand the court's jurisdiction beyond its intended scope. Justice Gorsuch articulated concerns about the implications of federal involvement in state disputes, suggesting it could set a precedent for future cases.

Miss Bennett, representing New Mexico, defended the consent decree reached between the states, arguing that it aligns with the compact's terms and merely refines existing methodologies for measuring water delivery. She emphasized that the compact divides the river's waters, but the specifics of those allocations have been a point of contention, with the court previously urging states to resolve such issues cooperatively.

The justices also explored the nature of consent decrees, questioning whether they should be treated differently in original jurisdiction cases compared to other legal contexts. The discussion underscored the complexity of water rights and the intricate balance between state and federal interests.

As the session concluded, the justices were left to ponder the ramifications of their decisions—not just for Texas and New Mexico, but for the broader landscape of interstate water rights and federal involvement in state matters. The outcome of this case could reshape the future of water management in the region, highlighting the delicate interplay between cooperation and conflict in resource allocation.
