Last weekend, four of us went diving at Dutch Springs on Sunday. All day saturday God was trying to drown this part of Pennsylvania. Ok, not really, but it did rain ALOT which resulted in a lot of sediment being washed into the quarry. I found out how much when we descended at the pumping station. I am practicing my bouyancy control, up, down, and sideways, controlling my descents as well as ascents. My buddy on the other hand later told me, "I don't add air to my BC until I reach the bottom". ANYWAY, we were maybe 10-15' apart going down, and I could barely see him. When I passed the 30' mark, it was like descending into pea soup. I could see, but there was no distinct light source. That was an erie feeling. We stayed withing 3-4' of each other as we followed the pipes to the wall and worked our way around.
