TopH2O - Depth of thermocline layer is different from one pond/lake to the next. Each water body has its own characters that make them unique. (many similar ponds in the region will also behave similar) Each has a pattern that tends to be consistant from one year to the next providing no unusual weather events occur. What you need to do is track the depth or decent of the thermocline of your pond over the coarse of a summer. It will usually remain similar after that, but as with everything else in nature exceptions do occur.
Deep water (14'-16') reef might only be used in the winter or during periods when oxygen is present around/in it.
