My two cents:
The things shown in yellow are the harder objects.
Those large yellow hooks are no doubt big predators.
The blue/purple stuff looks like bait balls.
The predators near the bait balls are probably more active/
feeding/more catchable.  Not sure, but some of the predators
may have crashed through the bait balls (those thick yellow spots).
It looks like you have some fish or rocks on, or near the bottom.

Those verticle streaks can be caused by a few things:
  1) One or more of your lines in the water getting within
      the transducer cone.
  2) Some hydrilla/grass/fishing line on your transducer.
  3) And this is the best scenario: They are smaller forage fish hauling
      ass to not get eaten.  This means that the predators are
      feeding.  It's Miller time. :)

Speedtroller:
 Your system looks to be tweaked extremely well.
 Those are some fantastic, clear images there.
 Everything in those images is clear and crisp.
 It just don't get any better than that.
 I wouldn't ever change a thing on your settings.

 Great job.

Fish Farts.  ;D
I think those diagonal lines are made by gas released from the bottom or something near or on the bottom (those smaller fish must have really been scared!).

itgeek and hb greg thanks for your input. as far as the fish and bait balls i think we are all of the same opinion. i have posted these same pics on a couple local forums here in georgia. in the responces i have recieved 99.9 percent say the lines are air bubbles coming from the bottom.. which now after thinking about it more. i do remember seeing a lot of that happening when we were in that spot. water was like glass so that makes a lot of sense. thanks for you`re input it is always greatly appreciated.
