Remedies

Affirmation of the district court's decision granting summary judgment in favor of the federal government.The ruling effectively upholds the federal government's exclusive authority to regulate water rights on federal lands within Idaho, invalidating Idaho's attempts to assert control under state law.

Scenario: You own land adjacent to a national forest in Idaho and want to divert water from a stream that flows through both federal and private land.

Your Rights: Your right to use that water may be subject to federal regulations and prior federal reserved water rights, especially if the stream originates or flows through federal land. Idaho's state water permit system might not be the sole determinant.

What To Do: Consult with an attorney specializing in water law and federal land management to understand how federal reserved water rights and the Clean Water Act might impact your diversion plans. You may need to navigate both federal and state permitting processes.

Scenario: An Idaho state agency is trying to impose state water quality standards on a federal wildlife refuge within the state.

Your Rights: The federal government's authority to manage its lands and resources, including water quality under federal law (like the Clean Water Act), likely preempts the state's attempt to impose its own standards on the refuge.

What To Do: The federal agency managing the refuge should assert its federal authority and rely on federal regulations. If challenged, they should cite federal preemption principles, potentially referencing this Ninth Circuit ruling.
