San Luis & Delta-Mendota Water Authority v. United States was a 2006 United States Supreme Court decision addressing takings claims by water districts arising from federal operation of the Central Valley Project and compliance with the Central Valley Project Improvement Act. The case involved disputes among the Bureau of Reclamation, California, agricultural districts in the San Joaquin Valley, and tribal interests including the United States Fish and Wildlife Service, with implications for federal liability under the Fifth Amendment to the United States Constitution and the Tucker Act before the United States Court of Federal Claims and the United States Court of Appeals for the Federal Circuit.
The dispute arose from operational changes to the Central Valley Project imposed to protect fisheries and comply with the Central Valley Project Improvement Act and species protection measures under the Endangered Species Act of 1973 and directives involving the Delta-Mendota Canal and San Luis Reservoir. Petitioners included the San Luis & Delta-Mendota Water Authority, the Westlands Water District, and other irrigation districts in Merced County, Fresno County, and Stanislaus County. Respondents included the United States, the Secretary of the Interior, and federal agencies such as the Bureau of Reclamation and the United States Fish and Wildlife Service. Competing interests included environmental groups, commercial fisheries on the Sacramento River, and municipal water users in Bay Area and Southern California served by the State Water Project and Central Valley Project exports.
Key legal questions concerned whether altered water deliveries constituted a compensable taking under the Takings Clause of the Fifth Amendment to the United States Constitution and whether plaintiffs had a claim under the Tucker Act's waiver of sovereign immunity in the Court of Federal Claims. Issues included the characterization of alleged property rights in water under California water law and federal reclamation law, the causation and traceability of injury to individual districts from federal actions, and whether a claim challenging interim operational criteria constituted a ripe justiciable claim under doctrines developed in cases such as Penn Central Transportation Co. v. New York City and First English Evangelical Lutheran Church of Glendale v. County of Los Angeles.
Petitioners initially sought relief in the United States District Court for the Eastern District of California and later pursued monetary claims in the United States Court of Federal Claims under the Tucker Act. The District Court handled equitable and declaratory claims seeking injunctions against Bureau of Reclamation operations, while the Court of Federal Claims addressed inverse condemnation and money damages. The proceedings involved extensive factual records about water accounting at O'Neill Forebay, operational rules at Keswick Dam, and biological opinions prepared by the National Marine Fisheries Service and United States Fish and Wildlife Service. The Federal Circuit later reviewed the compensation claims after appeals from the Court of Federal Claims.
The United States Court of Appeals for the Federal Circuit held that some plaintiffs had presented cognizable takings claims and that causation and traceability issues could be resolved consistent with Tucker Act jurisdiction. The Federal Circuit examined precedents including United States v. Causby and Montezuma Cty. v. United States in shaping standards for regulatory takings where federal operation of a reclamation project reduces water deliveries. The decision remanded certain claims for further factfinding on damages calculation and the existence of property interests under California statutory law and federal reclamation contracts.
The Supreme Court of the United States granted certiorari to resolve whether federal compliance with environmental statutes and biological opinions could give rise to a taking compensable under the Fifth Amendment to the United States Constitution when water deliveries were curtailed. The Court issued an opinion addressing justiciability, causation, and the scope of the Tucker Act, considering analogous decisions including Lucas v. South Carolina Coastal Council and Lujan v. Defenders of Wildlife. The Court's ruling narrowed available takings claims in the context of federal water operations by clarifying requirements for proximate cause and the nature of compensable property interests, and it remanded aspects of the case for further proceedings consistent with its opinion.
The decision affected water rights disputes across California, influencing litigation strategies by irrigation districts such as Westlands Water District and policy choices by federal agencies including the Bureau of Reclamation and the United States Fish and Wildlife Service. It shaped intersections among the Endangered Species Act of 1973, federal reclamation law, and state water law doctrines, and informed subsequent cases in the Federal Circuit and Court of Federal Claims about compensation for regulatory actions. The ruling remains relevant to allocations from Central Valley Project facilities like Tracy Pumping Plant and to negotiations involving stakeholders such as Metropolitan Water District of Southern California and environmental organizations like the Natural Resources Defense Council.
