|All Along the Outfall

I felt a little guilty asking Phil to take us to the White Point outfall pipe again. A boulder-buttressed, sand-flanked sewer pipe with a few strands of scraggy kelp doesnít promise a stellar underwater experience. It turned out to be a good call.
Off White Point, San Pedro CA, two reinforced, spun concrete pipes carry L.A. County Sanitation Districtís treated wastewater into the ocean on a daily basis. Lying between the main pipes is a double-barrel pipeline that extends to about 1 mile offshore. One leg serves hydraulic relief during heavy rains; the other leg is standby.

The eastern-most pipe is the one we dove. Ten feet in diameter, it has the most relief. Completed in 1967, it extends 2.25 miles offshore and empties in ~200 fsw.
We dropped anchor in 65-70 fsw. Given that it was a little dark and a little silty, the tangle of rocks and algae was bursting with some of our favorite photo subjects. Even better, the adjacent seabed tantalized us with a bonanza of newly deposited, glistening, squid egg cases. In some, development was far enough along that the embryos could be seen. Note the tear-shaped yolk sac and the faint red iris of the eyes (tighter shots).
Phil spotted this cabezon guarding 2 nests of eggs.
