Fly Fishing Yellowstone - Madison and Firehole Rivers

The Madison and Firehole Rivers have dropped and cleared considerably. No,
they are not in perfect condition but yes, you can catch fish in either river.
These conditions are expected to improve with time.

One of main hatches to concentrate on is the Pale Morning Duns. These little
mayflies can turn the trout on enough that you can have some great dry fly
action but they can also frustrate many anglers that don't pay attention to what
happens during the hatch. Catching trout on the PMD hatch isn't just a matter of
having a PMD dun imitation tied on the end of your tippet.

These mayflies are often mixed in with Blue-winged Olives. You first need to
determine which mayfly it is hatching and which one the trout are feeding on.
That is sometimes impossible to do. On cloudy, overcast days both of these
hatches last much longer than they do on bright, clear days. When both are
hatching, you may just need to change flies and determine what is going on by
trial and error.

In addition to the PMDs and BWOs, you will probably see two or three species of
caddisflies that are hatching. Don't think for a minute that the trout in the
Firehole River or the Madison River will prefer the PMDs or BWOs over the
caddisflies. These are the Spotted Sedges, the net-spinning caddis that are
more plentiful than any caddisfly or the White Millers (
Necopscyhe species) that
may be even more plentiful than the Spotted Sedges. There will also probably
be some Little Short-horned Sedges hatching. Writers would call this "multiple
hatches". I call it a mess to solve.

You should get to the river around 10:30 to 11:00 AM. They normally hatch
around noon. If the PMDs have been hatching during the past few days, you
may need to go much earlier and check the stream for PMD spinners. They may
fall late in the afternoon or early in the mornings.

Tomorrow I will get into the details of fishing the PMD hatch.
