Temperature for Lake Barramundi
by Johhny Mitchell
Paranoia and fixation with water temperature readings on the depth
sounders is common place with many barra anglers. Summer and Winter
fishing will see many anglers in search for the warmest possible
water theories govern angler movements in many cases, but does
it govern the fish in the same manner? If we all targeted warmer
water in winter we would all certainly catch fish eventually,
but is it a necessity for fishing success? Certainly Not!
If all barra searched for the warmest water in a lake in winter,
or summer, then 100% of the population would all be in one location,
and so would all the anglers. Now that's a lot of fish and boats
in one spot. But it's not so. On days where the conditions suit
for barra to move shallow in winter, there is also mass numbers
of fish staying deeper within the lake core, a minimum of 20-40
ft below in water up to three degrees C cooler than those barra
in the warmer shallows. Both schools of fish are catchable with
mid lake angling down to 30ft below in 15 Degree Celcius sub pockets
producing quality fish at select times.
are poikilothermic, which means their body temperature conforms
to that of varying water temperatures. Metabolisms adjust
accordingly.They can be caught in water that varies up to
1- 3 degrees celcius on any given day and at times the best
fishing comes from water cooler than warmer regions sounded.
Current flows, stability in temperature and digestive systems
of barra need close scrutiny. This chapter can expand your

surface temperatures on the day can produce the best fishing in
winter. Fishing the fringes in water that is cooler than that
of shallower back pockets will see many barra landed, so an angler
needs to expand on reasons as to why barra can be caught in contrasting
water temperatures. Is temperature as important as one thinks
for angling purposes? The winter of 2007 will go down as a harsh
period for landlocked barramundi in Australia. Awoonga's daytime
surface temperatures dropped to at least 14.9 degrees Celcius.
barra trips at this time saw up to two and three barramundi hooked
per session in these difficult circumstances. Lake Awoonga's barramundi
were still catchable in these ultimate extremes amongst chilling
South-West winds, so it's almost fair to say that it is never
too cold to catch barra in Lake Awoonga, but death is imminent
if conditions worsen. It
was basically the rock bottom balancing point.
lakes and blue skies allow sunlight to penetrate the surface.
A heat transfer occurs. Calm, cloudless nights and cool
air eat away at lake temperatures. Stable temperatures in
deeper zones as well as fluctuating surface layers are shifted
around the lake by wind born currents. Mixing occurs. Ideal
circumstances for fish can come and go. Extra thought needs
to be applied on when and why for best success.

a complete reversal, water temps in summer can reach 35 Degrees
Celcius in lakes and sensational fishing can be had in shallow
and deep regions, casting and trolling. There are 4 major terms
that come to mind with this temperature topic. Temperature fluctuation,
temperature stability, lake current flow and barramundi digestive
add further light on a central topic, successful warm water fishing
circumstances may quite often only appear one day a week in winter,
leaving an angler who hunts for warm water searching for Loch
Ness on the next six. Fish that search for a heat advantage do
so at a certain stage of digestion. Depending on what stage of
the bodily process these fish are at, some will and some won't
strike a lure or food offering.
when you visit a barra lake you wiill find fish that at times
look for the best suitable water to help digest food and others
that don't require that added help from mother nature at that
time. It solely depends on the water conditions created by the
weather. Variances in food item sizes taken by barra are often
dictated by times of stability and increase in temperature versus
times of fluctuating temperatures. Taking notes on temperature
movement and duration is a key. There is so much more than meets
the eye. Open minds open doors.
cool winter morining at Peter Faust Dam saw barramundi on
the prowl and striking surface lures just on and after day
break. Cool surface water and hungry fish. No need to wait
for waters to warm. Why wait for warmer water at noon? Some
great fishing is already over.
