Fishing this type of structure is guaranteed to hammer limits of fall trout. But what’s the easiest way to find them? Read on to see how!
Deep water is important to fish. When weather turns for the worst, they have a place to run and hide.
It’s the same thing for fish! Especially speckled trout.
Deep water is their “thunder bunker”.
It’s easy to locate them without even launching the boat, though you’ll have to fish them in order to see if trout are there or not.
This video does a pretty good job of explaining how, but if you want to learn the finer details of why trout go deep when the weather gets bad, then be sure to read the rest of the article.
Not because deeper water is warmer (warm water rises and cold water sinks), but because deeper water is stable.
Rolling waves and fast temperature changes affect fish in shallower water more strongly than fish in deeper water.
Fish metabolism changes with body temperature, which matches the surrounding water temperature.
And fish body temperature can vary as much as 40 degrees! If that happened to us, we would die.
But fish don’t.
They don’t die because they can adapt by changing their body’s chemical processes.
And this adaptation requires a “time out” to adjust.
This time out is reduced by inhabiting the stability that deep water offers.
Even during the summer deep water offers shade and cooler temperatures to rest in, so identifying and fishing deep holes is still a good idea, so long as they are near spawning areas.
Knowing the biology of your target species (in this case, speckled trout) is key to predicting what they will do next.
When using this knowledge, you’ll know where to go looking for them, and when you go looking for their “thunder bunkers” you’ll know exactly where to cast a line!
