Rangen, Inc. v. Idaho Dept of Water Resources

Appellant Rangen, Inc., filed a petition before the Director of the Idaho Department of Water Resources, alleging that junior ground water pumping in the Eastern Snake Plains Aquifer was materially injuring its water rights. The Director issued an order granting Rangen a curtailment of certain junior priority ground water pumping affecting Rangen’s water rights. The Director also interpreted the source and point of diversion elements of Rangen’s water rights to have a scope smaller than Rangen’s actual historical use. Rangen and intervenor Idaho Ground Water Appropriators, Inc. (“IGWA”) each filed petitions for judicial review. The issues raised by IGWA in its petition for judicial review were not at issue here; rather Rangen raised various issues related to the interpretation of its water rights and the sufficiency of the evidence before the agency. Specifically, Rangen appealed the Director’s determinations that Rangen could divert water only from the mouth of the Martin-Curren Tunnel and only within the ten-acre tract listed on its water right partial decrees. Rangen also appealed the Director’s adoption of an adverse expert’s analysis and the Director’s conclusion that junior priority ground water users are using water efficiently and without waste. The district court affirmed the Director’s orders, and Rangen appealed to the Idaho Supreme Court on substantially the same issues with substantially the same arguments. Finding no reversible error in the district court's judgment, the Supreme Court affirmed. View "Rangen, Inc. v. Idaho Dept of Water Resources" on Justia Law
