I know we’re about halfway through the diving season here this year, but I just got out for my first dive of the season this afternoon. I headed down to Cardinal, Ontario with my dive buddy and we dove on the wreck of the Conestoga. Our bottom time was about 50 minutes. The water was a balmy 76F and the viz wasn’t bad at all. I was quite surprised in the lack of significant zebra mussels on the wreck. My dive buddy and I were wondering whether the zebra mussel population is being reduced by being eaten by the gobies and/or the zebra mussels having been a little too efficient in their filtering of the water meaning they’re basically dying off for lack of food.
When I have a moment, I’ll see if I can post a picture of the dive profile from my dive computer.
