A comprehensive review of live, trusted news sources does not confirm the existence of a recent or breaking report titled or framed as “The West’s water war arrives in Washington.” Despite extensive searches across major international and U.S. outlets, no verifiable article matching this description, scope, or narrative could be identified.

While disputes over water allocation in the western United States—particularly involving the Colorado River Basin—remain an active and widely reported policy challenge, there is no newly emerging, standalone report documenting a specific escalation or event in Washington under the phrasing provided.

In the absence of confirmed reporting, producing a rewritten article that meets standards of factual accuracy and journalistic integrity is not possible at this time.

Further clarification or source material would be required to proceed.
