United States v. Black Canyon Irrigation Dist.Annotate this Case
This water rights appeal stems from two consolidated subcases, numbers 65-23531 and 65-23532, litigated in the Snake River Basin Adjudication (SRBA). The subcases concerned the United States’ late claims filed in January 2013, which asserted “supplemental beneficial use storage water rights” claims under the constitutional method of appropriation to store water in priority after flood-control releases. The special master recommended that the State’s motion for summary judgment be granted, concluding the Late Claims should be disallowed because, as the Director of the Idaho Department of Water Resources (Director) recommended, the Late Claims asserted rights that had not been claimed when the underlying water rights were adjudicated and decreed. Alternatively, the special master concluded the Late Claims should be disallowed because, as intervenor Black Canyon Irrigation District (BCID) asserted, the decreed water rights already authorized the rights the Late Claims now assert, and hence, the Late Claims were unnecessary. The district court agreed with the special master insofar as the Late Claims were precluded. However, the district court rejected the special master’s alternative recommendation that the Late Claims were duplicative of the rights already decreed and unnecessary. The district court entered judgment reflecting these conclusions. The United States appealed the district court’s ruling on preclusion, but finding no reversible error, the Idaho Supreme Court affirmed.
