Where are Deep Holes for Speckled Trout?

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!

How to Find Deep Holes for Specks

Deep water is important to fish. When weather turns for the worst, they have a place to run and hide.

Imagine this:

You are outside enjoying the 72 degree weather and shining sun. Suddenly, a storm blows in, ruining the great weather and sending you running inside.

It’s the same thing for fish! Especially speckled trout.

Deep water is their “thunder bunker”.

How do we find these deep holes?

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.

Note: this video is from Inshore Fishing 101, a course available inside LAFB Elite.



What does deep water provide for fish?


Not because deeper water is warmer (warm water rises and cold water sinks), but because deeper water is stable.

The strong west winds of a nasty cold front can drop water levels so fast that speckled trout in shallow water might find themselves exposed.

Rolling waves and fast temperature changes affect fish in shallower water more strongly than fish in deeper water.

Knowledge Bomb

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!

    Hey Robbie, I appreciate you commenting!

    There’s a few places they’re biting at, but I only disclose that to members of LAFB Elite.

    Awesome very informative

    Devin, I may have missed it but did u do a f/u from your trip 10/1/18. I enjoyed the preparation phase and wanted to view your results, especially since that area is where I enjoy fishing.

  • Fran says:

    Also, I like the bombshells on deep holes… tks

  • Devin says:

    You’re welcome, Francis! Thanks for being a regular, man!

    Devin, I thoroughly enjoy your wisdom and knowledge as it relates to catching speckled trout. I’m trying to learn how to use Google Earth as well as you do, but it’s a slow process. Today, you really helped me understand about deep holes, even thought as you stated, the water color all looks the same.
    One more comment if you do not mind. How can you find clear waters from Google Earth? If you mentioned this before, please accept my apologies.

    Hey Jeff, I’m glad to see you like this article.

    Very good news!

    Okay, to answer your question…

    Ya know, there are some good articles somewhere in here, but the really good stuff is inside LAFB Elite.

    Since you’re a member, here’s a link: https://www.lafishblog.com/courses/sfms-part11-finding-the-best-redfish-spots/

    You’re looking for the sections titled, “The Myth of Clean Water”, “Using Satellite Imagery to Find Awesome Redfish Ponds”, “Sorting Good Ponds From Bad” and “Identifying Consistently Clean Water”.

    That should keep you busy for awhile. lol
