Sad state that these ocean waters are in. The waters are not very clean here to begin with and having an environmental catastrophe such as this is just a further blow.
Last I heard of the supposed cause was that a boat’s or ship’s anchor may have caused the breach (unconfirmed).
We used to fish these waters when I was younger when my Dad had a boat (30 - 40 ft)…just sport fishing and going to Catalina Island and cruising the waters. It was great fun but lots of hard work when we were done…everything needed to be washed (boat, fishing poles, trailer) with soap & water to get rid of the corrosive salt water. That and getting the fish scales off of the fishing poles. and frequently tending to the Teak wood trim on the boat.
But we had great fun!
