The surface of the high desert lake is glassy. There are periodic splashy
rises, but you do not see any winged insects except for a cloud of black
midges above. Try a chironomid pupa. As the insect rises in the water
column they may be shedding their shuck before emergence. The trout glide
along the bottom in the flats of the lake, eyes looking upward. They key
on the movement the insect makes while removing itself from the shuck. The
fish skyrockets upwards turning at the last moment after snatching up the
helpless pupa. Small bugs, hard takes.
It is cloudy, dark and windy. You may be on any body of water. Nothing
going on that you can see. Try a streamer pattern. A baitfish imitation.
What color and size you ask? A good rule of thumb...Dark day, dark color.
Bright day, bright color. Higher background contrast. Larger patterns
will produce on these days. Big trout and wild fish are photo-sensitive to
sunlight. It is well documented that big browns feed nocturnally. Dark
days are great for big dark baitfish patterns. Bright sunny day, you may
want to try something with crystal flash in the pattern. Drop a hook size
or so for this situation. Silver or gold tinsel bodied flies work well on
sunny bright days.
We can get very technical about this also. Examining the undersides of
streambed rocks for nymphs, seeing what is holding in the vegetation along
the banks, using a specimen net to skim the water for exacting information.
Pumping the trout's stomach is the fun...You got to catch one first is the
problem!
Hope this will help you out a little when you have a problem deciding what
pattern to use.
Be the fly...Tom Loe
