Case Explained: YUROK TRIBE, ET AL V. KLAMATH WATER USERS ASSOCIATION, ET AL

Court: United States Court of Appeals for the Ninth Circuit Filed: 2026-06-17 Docket: 3:19-cv- The Ninth Circuit affirmed the district court’s ruling that the Endangered Species Act (ESA) applies to the Bureau of Reclamation’s operation of the Klamath Project and that the federal court had jurisdiction to decide the crossclaim seeking confirmation of this authority. The panel held that Section 7(a)(2) of the ESA, which mandates consultation to ensure agency actions do not jeopardize endangered species or destroy their habitat, applies because the Bureau retains sufficient discretion in operating the project; the Reclamation Act provides broad goals rather than specific non-discretionary mandates that would conflict with the ESA. The court reaffirmed *Klamath Water Users Protective Ass’n v. Patterson* as controlling precedent, rejecting arguments that Supreme Court decisions like *National Association of Home Builders v. Defenders of Wildlife* or Ninth Circuit cases like *NRDC v. Haaland* rendered *Patterson* obsolete, noting that *Haaland* concerned the reinitiation of consultation under specific settlement contracts rather than the general applicability of the ESA to the Project’s operations. Furthermore, the court determined that the district court’s decision did not constitute a “judicial taking” because it resolved a question of federal statutory compliance rather than adjudicating state-law water rights. Finally, the panel held that the doctrines of prior exclusive jurisdiction and *Colorado River* abstention did not bar the federal court from hearing the case, as the issue involved federal ESA obligations distinct from the state court’s ongoing adjudication of water rights priorities. The practical consequence is that the Bureau of Reclamation remains legally obligated to operate the Klamath Project in compliance with the ESA, including maintaining minimum water levels and stream flows for endangered species, and the district court’s declaratory judgment confirming this authority stands.
