Overview
Case summary
This Supreme Court case involved a dispute between Kansas and Colorado over the waters of the Arkansas River. Kansas sued to enjoin Colorado from diverting water for irrigation, claiming it diminished flow into Kansas and injured agriculture and property. The United States intervened, asserting federal power to control waters for reclamation of arid lands. The Court held it had jurisdiction over the interstate controversy. It rejected the federal government's claim, finding no constitutional authority for reclamation control within States. On the merits, the Court applied the doctrine of equitable apportionment, balancing Colorado's substantial benefits from irrigation against Kansas's minimal proven injuries. It dismissed the suits without prejudice, allowing Kansas to seek relief if future diversions destroy the equitable balance. The decision established important precedents on interstate water disputes and federalism.
Abstract
The Supreme Court exercised jurisdiction over a dispute between two states concerning diversions of river water for irrigation that allegedly diminished flow and injured downstream agriculture and property. The federal government intervened claiming authority over reclamation of arid lands, but the Court rejected this assertion of constitutional power. Applying equitable apportionment, the Court balanced the upstream state's irrigation benefits against the downstream state's injuries and dismissed the suits without prejudice, permitting future relief if diversions materially disrupt the balance.
