The Navajo Nation will argue Monday at the Supreme Court that the United States must meet the water needs of their reservation in Arizona, amid long-standing tensions about how to apportion the dwindling flow of the Colorado River.
In the first oral arguments of a two-week sitting of the high court, the Navajo will defend a ruling from the U.S. Court of Appeals for the 9th Circuit that kept alive their long-running legal effort to force the government to come up with a plan to provide enough water.
In court filings, the tribe contends that an 1868 treaty promised both land and water sufficient for the Navajos to return to a permanent home in their ancestral territory.
