From the Washington Regs:
COLUMBIA RIVER – where the river coincides with the boundary between Washington and Oregon, the license of either state is valid. Anglers
must comply with the laws of the state in which they are fishing. An angler licensed only in Oregon may not fish on the Washington shore or in
Washington sloughs or tributaries. An angler fishing the Columbia River is restricted to one daily limit even if licensed by both states.
From the Oregon Regs:
1. In the Columbia River where it forms the state boundary line, not including tributaries, sloughs and lands, the following rules apply:
a. License and tags of either state are valid except when the other state’s season is closed;
b. Anglers must follow the rules of the state in which they are fishing;
c. Anglers are restricted to one daily catch and one annual sturgeon catch limit from the Columbia River, even if licensed
in Oregon and Washington;
d. Anglers that are residents of either Oregon or Washington may launch or take out their boats from either shore, regardless
of which state license they hold;
Only one limit regardless.
