BISMARCK, N.D. — Officials in Missouri and the Canadian province of Manitoba are appealing a federal judge’s decision that would bring Missouri River water to residents of northwestern North Dakota.

North Dakota Attorney General Wayne Stenehjem called the appeal filed Tuesday a “disappointment.” He says specific legal issues being appealed have not been disclosed.

Judge Rosemary Collyer in August ruled that the $244 million Northwest Area Water Supply project complies with federal environmental law.

NAWS was first authorized by Congress 31 years ago but has been tied up in the courts because the state of Missouri and the Canadian province of Manitoba have concerns about water quality and water depletion.
