Fall Fishing Fall starts getting real in
October. Some days can
be nice in the afternoon,
With Bro but you can usually plan

on it being a little chilly,
(A Look Back At Early Fall) especially in the mornings.
By Brian Brosdahl
Most deep lakes in the Ice
Belt have their

thermocline disappear in
September and the lakes
usually go through
turnover in early October.

Large shallow lakes or

shallow bays of large lakes
do not set up a
thermocline during the
summer because the
entire water column gets
turned-over every time
there is a heavy wind.

Deep lakes set up a
thermocline during the
summer. The thermocline
is simply the narrow band
of water that separates
the warm upper level of
the lakes from the cold

lower level of the lakes
that often runs out of
suitable oxygen later in
the summer.

If walleyes live in a shallow lake, many of the fish tend to move shallow as soon as the water cools
down and becomes more comfortable for the fish.

At the same time, fish living in deep lakes have been located above the thermocline during the heat of
summer, so they seem to be anxious to go into deeper water as soon as the water cools and the
thermocline disappears.

This means there are walleyes and other fish heading in opposite directions during the fall, depending
on what type of lake or what part of the lake the fish are located.
