    Nice article I have read it several times.

    The logic would be following the information presented that measuring the oxygen level at various depths would be an important auxiliary to watching changes in pressure. Unfortunately measuring oxygen just doesn't seem practical.

    How does the thermocline relate to the advice in the article?

    I think I wrote an article pertaining to that topic but I'm not sure how relatable it is.

    Most of my thermocline work has been done in the great lakes where there is a VAST break and tempurature difference. In a lot of instances, we use thermoclines there just as you would structure in most other bodies of water.

    Thermocline in the great lakes is most often effected by wind direction and wave action than anything else. You can have mid July days with a south wind that brings up really warm surface water. The fish will scatter (salmonoid species) as they just cannot stand that tempurature. You concentrate on tempurature breaks to find fish. When the North Winds blow, it will start to mix the cold and warm water and develope those thermoclines. We are not talking little ones in some lakes that can be in a hole or on the edges of streams. We are talking break lines that extend down 40 feet and might run 15 miles!

    I suspect that pressure "could" push those break lines down with high pressure and bring them up with low pressure. More than anything, we look for winds to change our thermoclines more than pressure. Again, not really sure how relatable it would be to really small bodies of water (compared to Lake Michigan that is)!

    Supposedly, fish feed more on a rising barometer than on a falling barometer. They also like to feed when the barometer initially starts to fall, but not for too long after the barometer starts falling.

    Good luck!

    I look at the barometer and see what it says just to help me figure how and what the bite will be. as stated earlier I go anyway and just enjoy the day

    I don’t know what it was today, but myself and another boat on the lake did terrible today. A week ago they were jumping in the boat, same lake, same depth, speed, technique, same water temp, same everything. The only noticeable change was wind direction and speed, but not significant. I think barometric pressure has an effect, as well as moon phase, weather fronts etc. I’m with the others though, if I can go, I’m going.

    I get out as often as I feel like it and when I remember to, I’ll check pressure and wind direction before I head out. If the pressure is over 30., I know the fish will be either deeper or buried in the brush piles. Some days both. Wind direction helps me pick out an area to fish before I even launch the boat. Neither will stop me from going and enjoying the day on the lake.

    Thirty plus years ago my friends Grandpa who lived and had a boat house on the lake kept a mason jar filled with water with an empty mountain dew bottle upside down in it. When the water covered the words "Mountain Dew" he would fish, by the time the water would reached the rifle he would usually have a limit. Since he lived on the lake he didn't waist time if they weren't biting.

    On a falling Barometric pressure most time will bring rain or some other Percipitation in.

    Another "twist" to all this is that most info on the barometer's effect on fish .... says it's is on relatively "shallow" fish. Fish in the deeper portion of the water column don't seem to be affected as much, if at all.

    We already know that critters seem to know, sometimes ahead of time, when the weather is going to make a change. That change in barometric pressure could possibly be "felt" by them, and instinct or prior experiences may warn them of those changes. Nature's wild critters are usually more "in tune" with their surroundings than we are, since they can't artificially change them, so they've adapted to deal with them.

    "We already know that critters seem to know, sometimes ahead of time, when the weather is going to make a change"

    They know their habitat far better than we do.
