In re Rights to Waters of Yakima River Drainage Basin (Acquavella)

The issue before the Supreme Court in this case concerned the adjudication of water rights in the Yakima River Basin. The parties brought various challenges to the conditional final order of the trial court determining their water rights. The Court of appeals transferred the case to the Supreme Court for direct appeal. Upon review, the Court reversed the trial court’s decision concerning the quantification of irrigable land on the Yakama reservation, and reversed the trial court’s determinations regarding the Nation’s right to store water. The Court affirmed the trial court’s conclusions regarding the rights of nontribal claimants to excess water, but reversed the application of the “future development excuse” under RCW 90.14.140(2)(c) for nonuse of a water right. Finally, the Supreme Court affirmed the trial court’s denial of several individual water rights claims.
