To understand the war over salmon, we have to go back to 1855. That’s when chiefs from the Yakama Nation and other Pacific Northwest tribes signed treaties that are still used as the basis for laws and policies around salmon fishing. Some tribal members believe the Yakama signed a treaty under duress. In some ways, this document represents the first of a multi-generational series of promises the U.S. government made and broke. It also created a powerful legal framework the Yakama still use to advocate for fishing rights.
