    Thermocline?

    Only saw this in a few spots I was fishing yesterday, Am I seeing the thermocline?

    Don't know what it is but I really don't think it's a thermocline. From what I see in the lakes I fish the thermocline is a much straighter line. This looks to have an arch to it. I've to some pretty pics of what I see but I've never posted one? If you'd like to see.... I'd give it a try

    I'm not a graph guru by any stretch of the imagination but I don't believe that to be a thermocline. From pictures and articles I've never come across a thermocline at that depth in 55° water. I would think at that temp the lake/reservoir was pretty much turned over.

    Not the same but one lake I fish there is a I think they are called Phytoplankton as evening arrives and getting darker you can watch them rising off the bottom. Has to be deeper then 25 feet as it gets darker the whole screen starts to fill up with it. It looks just like the first pic in Waynes post.

    This is an early morning plankton column. It was gone about 3 hours later when I passed over the same area:

    So we've established it's not the thermocline or phytoplankton. Could it just be a setting? Sensitivity and Contrast are still default

    looks like a blue back herring school. that is how they school up. same for alewives. Threadfin and Gizzards make the balloon shape. The brighter the sunshine, the higher in the water column they will come which is why you can get great topwater in the middle of a sunny day. Threadfin do the opposite.

    Posted the pic on a local fishing forum and a couple folks chimed in saying it's probably perch. One guy said he saw the exact same thing and he started jigging and pulled them up one after another.
    Makes sense as there are perch in this lake
