Have fished the Mouth of the Kalama area a few times to date and haven't seen a decent day there yet (other than 1 day of good C&R for Nates) trolling or anchoring!!And with the mud coming down the Washington rivers right now, I think I'd look for a spot on the O-side, like down below Willow Grove at Stella or County Line over on the Oregon side.

Good luck, where ever you wind up!
