Text: Our role is not to pass judgment on the economic policy implications of the Red River Compact. Our role is to ascertain what the Compact says about state regulation of apportioned water. We hold that the Red River Compact insulates Oklahoma water statutes from dormant Commerce Clause challenge insofar as they apply to surface water subject to the Compact. We also uphold the Oklahoma statutes against Tarrant's preemption claim. We do not address Tarrant's challenge to the Oklahoma statutes insofar as they apply to water not subject to the Compact because Tarrant's claim on that issue is not justiciable. After oral argument, Tarrant moved to strike certain parts of OWRB's supplemental appendix regarding the Reach II, Subbasin 5 issue because the district court had declined to consider the additional materials. We take the Reach II, Subbasin 5 issue to be a matter of Compact interpretation and need not consider the supplemental materials. Therefore, we dismiss the motion to strike. The district court's grant of summary judgment to OWRB on the dormant Commerce Clause and Supremacy Clause issues is AFFIRMED. The district court's dismissals of the Stephens County and Apache Tribe claims as not justiciable are AFFIRMED.
