I have done approximately 12 dives here spanning from August to December 2003. The best vis was in late September to October which was around 15 to 20 feet. Lots of perch, lingcod, rock fish, greenling, etc. Not much for crabbing though. I have dove slack and during tidal exchange either of which you can do. If diving during tides, plan on doing a semi-drift dive. Overall, pretty good.
