Blaine, I used to work for Jones...in 07 in fact, so maybe I did the supplemental stocking. The water hasn't reached the furthest post location yet, but soon will if we get much precip. Good advice on the ice and setting the joists. water line is known to the nearest .01" with our laser so that shouldn't be a problem. What I am wrestling with is how close to waterline to set the joists. We have a relatively small watershed and dry summers like the last two will most likely leave the presence of a "high dive" off the decking to the water!
