Agua Caliente Band of Cahuilla Indians v. Coachella Valley Water District

By
In this interlocutory appeal, the water agencies challenged the district court's grant of partial summary judgment for the Tribe and the United States. The judgment declared that the United States impliedly reserved appurtenant water sources, including groundwater, when it created the Tribe's reservation in California's arid Coachella Valley. The court concluded that in the Winters v. United States doctrine, federal reserved water rights are directly applicable to Indian reservations and other federal enclaves, encompassing water rights in navigable and nonnavigable streams; the Winters doctrine does not distinguish between surface water and groundwater; rather, its limits derive only from the government's intent in withdrawing land for a public purpose and the location of the water in relation to the reservation created; because the United States intended to reserve water when it established a home for the Tribe, the court held that the district court did not err in determining that the government reserved appurtenant water sources—including groundwater—when it created the Tribe's reservation in the Coachella Valley; and the creation of the Agua Caliente Reservation carried with it an implied right to use water from the Coachella Valley aquifer. The court held that state water rights were preempted by federal reserved rights; held that the fact that the Tribe did not historically access groundwater does not destroy its right to groundwater now; and held that state water entitlements do not affect the court's analysis with respect to the creation of the Tribe's federally reserved water right. Accordingly, the court affirmed the judgment. View "Agua Caliente Band of Cahuilla Indians v. Coachella Valley Water District" on Justia Law
