I don't believe it's a legal requirement to have a rot cord in Oregon -- Washington and California, I believe it is. I've never crabbed at Yaquina (which seems odd for me). But pretty much any of the coastal bays will have crabs with the lack of rain (although I'm guessing Astoria/Columbia sucks right now with the high water... just a guess).
Tip: Seals and sea lions generally leave poultry (bait) alone. Not always the case with fish bait. If you get poultry ahead of time, if you have a place you can put it outside without critters getting to it, do so. The stinky and nastier the better, in my experience (but less pleasant to handle). Don't drop traps in the channel, but often just to the sides can be a good spot.
