Fly Fishing Freestone Rivers
In the first of this series on types of rivers, we examined the
pristine spring creek. In this second part of the series we will
look at freestone rivers. Freestone rivers make up the majority
of the world's free flowing cold water rivers. So named for the
rock and gravel that make up their riverbed. As most fly
fisher's know rock and gravel are vital to trout, steelhead,
salmon and other species that rely on these substances to make
their redds during spawning season.
Typically, for fly
fishing, freestone rivers are of most importance in the
mountainous regions. Where snow melt, glaciers, springs, and
rivulets, come together to form a river. Usually a fast flowing,
cold, well-oxygenated river. One that has aerobic, active forms
of life including insects and the corresponding fish that lives
on them. Because of the rock and other debris that line the
freestone bed and banks, trout and their insect prey have an
array of places to lie. The currents, however help the trout
with their turbulence, and whirling nature constantly offer up a
plethora of insect life for the choosing.
It is a double edged sword however, as the freestone giveth, the
freestone taketh away. No other major river form in this series
suffers so much from the forces of nature. Temperatures can be
extreme as are water flows. Flash floods can give way to drought
conditions in some cases over night. As well as longer cyclical
climate forces can enforce their will. Both insect and fish
populations can fluctuate wildly.
But what thrives is the heartiest of the hearty. Fish that used
to having to survive, indeed it is in their DNA, as well as the
flies. Stoneflies, mayfly crawlers and swimmers, and those
glorious caddis flies all call freestone rivers home.
When heading out to fly fish a freestone rivers, be ready with a
myriad of fishing flies.
The infamous patterns that conjure up afternoons spent fighting
and releasing feisty hard nosed trout will all be effective in
the freestone. Nymphs including the biggest names, Hare's Ear,
Pheasant Tail, Prince, and dry flies like Adams, Parachute
patterns, as well as hair wings, all were made for freestone
rivers.
Iin the early season be ready for high, fast and cold water.
Wading can be dangerous, but often unnecessary as high waters
will bring fish close to the bank, taking advantage of pockets
and undercuts, that normally are not there. And, remember that
river bottoms can change over the winter, so even a familiar
river can have unforeseen wading hazards.
