About three years ago I did a dive I refer to as the "milk dive". Our local quarry has Wednesday night diving (which is great for those of us that usually are stuck doing other things on the weekends) and this was one of those nights...There was a series of storms going through the area, but they were done and gone away before it was time to jump in. It WAS; however, drizzling slightly when we all arrived, so we set up on the lower access under the pavilions. Since it was raining that night, we figured that it would be deserted, and it was, but die-hards we are, we decided to go with it. Being that we were at the lower access, we entered there. We walked out about 20 yards to where it started to drop off, and then did a little surface swim to get out to the 15 ft. water. We gave our signal, and descended. THere were three of us, Two regulars and a guy that wanted to give the Wednesday night thing a go. AS soon as I dropped down, I looked at my computer to watch my descent rate, and couldn't see it in front of my face! So I moved it closer, no luck...after about 30 seconds to a minute, I ascended to see if the others were still down and I just surfaced in time to see their heads popping up about 10-15 feet away from me! Needless to say we couldn't continue at that area, so we decided to swim over to what's known as the bowl area and see if it was clearer over there...THANKFULLY it was and we didn't need to abort the dive. (yeah, lug all that gear, set it up, get it wet for a 1 minute dive! ) It was like diving in a glass of milk the run off was so thick! Now normally the quarry is about 3-5 ft visibility during algae bloom time, but this was crazy!
We dove yesterday and the visibility was about 20+ feet...not too bad!
