9th Circuit opinion on federal reserved right to groundwater

The United States Supreme Court did not accept an appeal of the 9th Circuit’s ruling on federal reserved rights in the landmark case, Agua Caliente Band of Cahuilla Indians v. Coachella Valley Water District, et al., upending almost a century of understanding about the difference between federal, state and private rights to groundwater vs. appropriable surface water.  This means that expensive litigation is in the future, as case goes back to the federal district court for determination of the quantity and quality of groundwater to which the Tribe has a claim.
