Thanks T. I definately saw the same stuff a little earlier on the local lake.

Here's a tip to maximize the use of your fish finders display area is once you find the thermocline is to maximize the screen area for "fishable" waters. Since most fish cannot survive below a thermocline since the oxygen level is too low. Instead of looking at the entire water column use the MAX Depth Feature and remove the "unfishable" water from the display and it will increase the amount details you can see in the waters fish can live.

Here is an image of the Humminbird 798c in Auto Depth Mode:

If your targeting fish or thermocline is at a know depth you can set a MAX Depth like I did in this image at 40 foot and increases the size of the details and makes it easier to target the fish.

IF you set Max Depth it will place an "M" next to the Bottom Depth Reading to show you are setting the Maximum Depth to view. Make sure you reset to auto if you want to navigate and see the bottom.

Thats great stuff, but is it a thermocline or a chemocline? Some say they
are analogous, I've been reading alot about this and NOAA is doing a very
intense study. That whole crowd is split, some say a thermocline is 39* with
only a couple degrees varience through-out the year. The chemocline guys
say its the specific gravity that seperates them, with hydrogen sulfide
being the main ingredient, along with others including tannic acid. Basically
the by-products of decomposition. Anyhow you look at it we're about to get
even more advancement and a better understanding of what exactly we are
seeing with our electronics. I think of the water as a pair of "photogray"
glasses, the deeper you go, the less light there is. Clarity and turbidity
affect plant growth, which in turn relates to DO, but I'm no rocket scientist.
