Lead Bouncer,

While tribal fishermen may fish the LCR, as far as I know, no treaty tribe has adjudicated (meaning approved by a federal court) fishing rights in the LCR as "usual and accustomed fishing area." That would prevent them from fishing in the LCR unless WDFW, ODFW, USFWS, and NMFS gives at least a tacit approval, as in failure to object implies consent.
