Scientific Thermocline....

[Doug Vahrenberg]

No the Thermocline is the bottom level of where fish can live. They can be anywhere from the surface down to that level so it helps to eliminate unprodcutive waters. But many times in clear reservoirs the fish like to live as deep as possible so they can hide in the shadows if no cover exists. Using your fish finder to find the depth the fish are helps when the fish are inactive and won't chase for dinner. Guess it's like walking in to a fast food restaurant or going thru the drive thru sometimes you like to go in and other times you just don't want to leave the comfort of your vehicle. Sometimes fish will travel for food and sometimes they want it the easiest way and that's close to the comfort zone or summertime home like at the edge of a thermocline.

Ah! In fast food terms I understand. Only the agressive fish move much to get your bait. The fish that waits near the thermocline under the shad ball for some of the shad to fall down to them to eat are often the larger fish as they don't expend as much energy to get their food. I want to catch the drive through fish!

Thanks again for sharing. You always educate here and on the boaters forum.
