Catching Yellowstone Cold Water Trout - Part 16
continued from Part 15

This article continues with hatches of baetis, Blue-winged Olives during the
winter months or cold water. If the water and air is cold, the Blue-winged Olive
duns will ride the water for a relatively long time. Often the problem with it is that
the trout are also cold and as a result, are not very active. It is much easier for
them to take the nymphs and emerging nymphs in the surface skim than it is the
duns. Later in the year when the water is warmer, they tend to take the duns
much better. Unless the weather has turned cold, the dun imitations usually work
great. In most cases you will be fishing water between forty-five and fifty
degrees. The trout will occasionally take a dun imitation under those conditions
but you odds of success are much greater fishing a nymph or emerger pattern
when the hatch is underway.

Getting the trout to take your imitation over the real ones can be a challenge. If
you spot a trout feeding on the surface, the best procedure is to present your
nymph or emerger imitation to it in a timely manner. Most of the time you will
probably have to fish the current seams that are adjacent to pockets that I
described in yesterday's article.

We have two "Perfect Fly" imitations for the emerging BWOs. One of the most
successful patterns for this hatch is the trailing shuck version of the emerging
dun. It imitates a dun that is still stuck to its nymphal shuck. A Blue-winged Olive
hatch in cold water has more than its share of cripples. Apparently, the trout are
aware that duns still stuck to their shucks are easier to catch because trailing
shuck patterns works great in the cold water.

Our other emerger fly imitates the nymph when the wing pad first opens before
the shuck comes off. It has a CDC wing and is designed to float flush with the
surface skim like the real emerging nymphs. You will probably get more takes
using it but you want get as many hook ups because it is more difficult to detect
the takes than it is using the trailing shuck version. You will usually see the trout
take the trailing shuck version but that isn't necessarily the case with the CDC
emerger. You have to watch your leader much closer.


We will continue tomorrow.........
