Subject: Thermocline?


Would like to know about Thermocline and how it relates to fishing. A
lake that I like "Shabbona in IL" in the map details says a Thermocline
forms in the summer around July.

Thanks Ray


Steve is pretty much right on about what I understand about thermoclines.
There is one thing I would like to add. The thermocline is sometimes
readable on your graph if you turn off the fish id function. Sometimes its
necessary to manually adjust the sensitivity too. Anyway, the way I
understand it is that at night the plankton in the water tend to concentrate
just at the bottom of the top layer of water. This is what you are seing on
your graph. As the sun comes up and the day wears on they tend to shift up
and spread throughout the warm upper layer casuing the thermocline to become
more difficult to read. This does not mean its not there. The importance
of the thermocline is multi fold. Because the plankton concentrate at that
level often bait fish and therefore predatory fish will too.
