- A clear 20 feet (outgoing tide)
Good viz and easy swim at high slack tide. Current picked up heavily by the end.
So much marine growth you could barely discern the bottom of the bridge piers! Tens of thousands of feather duster worms covering all hard surfaces. Tons of kelp greenlings, crabs, and big pile perch about.
Dive report for 3/8/25

- 20 feet
Great conditions at a great site. Had the first 70min as near total slack along bridge pilings before ebb picked up. Dive start 10:47am and exit at 12:42pm. Water just clear enough to look up from 35ft and see the dark outline of the bridge above to navigate between pilings. Pilings covered in short plumose anemones (mostly white but some orange, yellow/green, and creamy ones too). Yellow and orange sponge, huge clumps of feather dusters and invasive bryozoans.
