The Cherokee tribe owns a section of the Arkansas River in Oklahoma that has been appraised at $15 million. The ownership of the river bed is in dispute and is the subject of litigation. The U.S. Supreme Court ruled in favor of the tribes in 1970, but the matter still needs to be resolved by Congress. The appraisal includes land beneath the water, sand, gravel, and mineral resources. The Corps of Engineers is involved in the Arkansas River navigation project, which is also part of the dispute. The Cherokee tribe should be compensated for their river property according to their attorney.
