The states of California and Oregon have both tried to challenge Klamath tribe's water rights, but have been rebuffed. Local farmers tried unsuccessfully to claim water rights in the 2001 cases, "Klamath Water Users Association v. Patterson" and "Kandra v. United States" but these were decided in favor of the Department of Interior's right to give precedence to tribal fishing in its management of water flows and rights in the Klamath Basin. In 2002, U.S. District Judge Owen M. Panner ruled that the Klamath Tribes' right to water preceded that of non-tribal irrigators in the court case "United States vs. Adair," originally filed in 1975.
