The Choctaw Nation and the Chickasaw Nation filed suit in federal court to prevent the sale of water by the state.
The tribes sued the Oklahoma Water Resources Board and Oklahoma City. They want the state to negotiate agreements with them.
Oklahoma City gets half of its water from lakes within the tribe's former reservations, the city manager said.
The tribes say they still own rights to those lakes through the 1830 Treaty of Dancing Rabbit Creek.
