Fish shallow in the spring, go
deep durirtg the heat of the
SUmmer, come back toward the
surface as autumn temperatures
COol the upper waters, and plunk
for the depths again during the
r months.
In general, this rule for the
anler can be followe5 with con-
fidence throughout t h e year
When fishing in Oregon lakes
for mt species of cold water
I.i. There are plenty of excep-
" u''to'this,general-rule, but.we
n safely say that anglers will
experience the best Success if
*. they follow the "thermocline."
'During the'summer a lake un-
normal circumstances be-
e stratified into three lay-
ers: the warmer upper portion
and the much colder deep por-
tion separated ,by a layer of wa-
ter !led the th.ermocline in
temperature change is ra-
" mra its top to its : bottom.
athis thermocline has a deci-
d"iiifluence on your angl'ng:
Bear in mind that during the
summer the position of the ther-
aOcllne depends to a great deal,
ln the total area over which
tile Wind has full opportunity to
ert its influence. In general,
smaller the surface area the
gher will be the: position of the
aermocline. In addition, there
aasome lakes, especially the
llow ones, where stratifica-
tion is uncertain. There are all
gradations between those lakes
Which are too shallow to stratify
and:the &ep ones where stratifi-
cation is positive.
EXamples of this stratification
mi..ht be Sv,uth Twin lake near
Wkkiup reservoir as compared
to Odell or Paulina lake. At the
former the thrmocline may de-
velop no deeper than 15 or 20
feet below the surface, while in
the latter • two the thermocline
may be as deep • as 60 to 100 feet
or more. I am certain that many
uf yu readex:s, while swimming,
espeeiall.y du.ring the early part
of the summer, have suddenly
encountered a cold strata of wa-
ter .pe'haps 10 Seetor so bentatl

As kfds we believed this to be
caused by a cold, underwater
spring, and it was considered a
daredevil feat to dive down into
this cold strata of water. Little
did we know his phenomenon
was the •development 'of the
thermoeline, the annual stratifi-
cation of a lake.
We won't go into the chemical
and biological complex of a
lake. Needless to say, there is no
such thing as chemically pure
• water. Such water voiald be a
biological desert. "The existence
of life within water depends up-
on the presence of that miscell-
aneous array of substances, and
in a general way, the richer the
contained substances the greater
the prod, uctivity.
The thermocline i s actually
the transition zone between the
warmer and more productive up-
per waters ,of a lake and the lo-
i wer, colder section. Although
oxygen depletion may occur in

ihe deCOr @orUon;,. the co ae
water has a greater ability to
retain oxygen than the warmer,
upper area. Depletion in the 1o.
wer depths may occur when the
xygen consuming processes oc.
:ur at a more rapid rate than
the oxygen supplyinz proce,:cs.
Even though the loss of oxygen
i is more rapid in the upper area,
it is kept well supplied through
wind and wave action.
The basic food for all life
within a lake, including fist, is
the many forms of small plants
and animals known aa planiAc...
Phytoplankton (plants) sustain
life through the process of plto-
tosynthesis and their depth with-
in a lake depends upon the
depth of light penetration a::
well as water temperature. Zoo-
plankton (animals) follow their
food source, the phytoplankton,
but here again, these animals
are directly influepced by lighl
and water temperature. In othe
words, within the plankton com-
plex there is°a series of organ-
isms which lifts "potential f-
stuffs to different levels of avail-
ability, beginning with the inor-
ganice materials and culminat-
ing in small but highly organi-
zed plankton animals which in
turn become one of the main
ing c'(nditions.
To illustrate • how pro/oud this
may be, game commission biolo-
gists working in diving suits at
Odell lake last summer obse."v-
ed within the thermocline a thin
layer of plankton so dense it
was impossible to see through it.
As one skin diver reported, "the
layer was so dense it was like
l:,oi,:ing at the edge of a flat
sheet of metal." AboVe or below
this edge the plane extended out
as far .as the worker could see
under the availabie light condi-
tions. The abundanoe el plank-
ton at or near the thermocline
was also revealed by towing
plankton nets at various depths
and at periodic intervals during
the summer.
The vertical distribution el
plankton through the summer
tollows closely the temperature
changes as well as the light.pen-
etrati0n and degree of intensity.
Daily migrations occur among
some species, toward the surface
at night and in the reverse direc,.
tion with the onset of daylight.
Perhaps this might, explain in
part why angling is eonsidered
best during the early morning
hours and again Just . before
nightfall. ,

mind let's take a look at what
might happen over the course of
a summer.
In early spring the food s(mr-
ce for fish (plankton) may be
well distribute_d throughout the
water of a lake. Water at this
period is of a uniform, cold tem-
perature and light intensity is
soft. As spring progresses and,
surface water warms, the plank-
ton complex seeks its tempera-
ture requirement and moves to
lower levels. The intensity of the
light also increases; and since
most forms of plankton require
the softer, ultraviolet rays, this
too causes a downward migra-
tion toward the depths. During
the peak of the summer there
may be a heavy concentration of
plankton near and within the
thermocline strata since this at-

and therefore, are but indirectly
