.............................Fly Fishing Yellowstone National Park


I am calling this series Yellowstone Journals and Additional Information. It is a collection of a
rambling mixture of experiences on the streams with some notes, tips and additional
information thrown in. Some of this comes from my video tape logs (record of video shot)
and  notes made on my daily note books.

Fly Fishing the Gallatin River - Part 3

As soon as the water clears up from runoff the insects begin to hatch (some
hatch before it ends) and the Gallatin River comes alive. The trout spent a long
time in very cold water and seem to want to eat everything in sight. There are an
amazing number of aquatic insects in this small river. It seems like when the
hatches start, everything hatches at once. Of course that is not exactly the case
but there are a lot of different insects that hatch at the same time. Thank
goodness, the trout don't become very selective in the section of the Gallatin in
the park. The just line up at the ends of the current seams and the ends of the
runs and feed.

The river is usually deeper on one side than it is the other even when there are
no turns in its course. There are a lot of undercut banks. By the way, there are
also some deep holes along the stream. If you are not careful you will step into
one not noticing it in the thick grass. They can be three or four foot deep so it is
possible to break a leg or at least take a hard fall. When there is no hatch
underway, one of my favorite ways to fish the river is to walk the banks in an
upstream direction, casting ahead and allowing the fly (usually a terrestrial) to
come back downstream close to the banks. I usually cover a lot of water fairly
fast this way. Tomorrow I will tell you about stepping in one of the hole but today
I will keep on the fishing.

When the hatches end in the afternoons before any spinners start falling or the
caddis start laying their eggs, the terrestrial patterns will usually work fine. Grass
hoppers, beetles and ants work especially well if you keep them close to the
undercut banks. There are a lot of natural insect that get into the water along
the banks. A dropper rig with a hopper on top and a mayfly nymph or caddis
larva imitation dropped a couple of feet below the hopper works well on the
cutbows. It works well on the whitefish too and sometimes you get more whitefish
on the dropper fly than trout.
