Tahuya was used to be decent about 5 years ago but has really gone downhill. The Dewatto can be fair to good but timing the runs is really tricky and can vary by more than a month. They both get hit a lot by indian netting. I've even seen the nets draped fully across the river mouths.
Make sure you are watching the regs closely (pinched barbs, releasing all SRCs, etc.). I am glad to see more fish and game patrols out there. Depnding on where you are coming from there a lot better fisheries without the drive into oblivian.
