.............................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 Upper Madison - Part 4
This continues the hatches that were covered yesterday in part 3. Another mayfly that hatches in the Upper Madison is the Western Green Drake. We have not found this one in large quantities on the Madison in the park, but we would suggest you have flies available in the event you encounter a hatch. It starts about the middle of June and last until the middle of July depending on the particular section of the river. The hatch usually occurs mid-day, depending on many factors and the spinner fall usually occurs near dark.
The next hatch we show is the Pink Ladies. These mayflies are the Epeorus albertae species which are clinger nymphs. These are also called Slate Cream Duns. Eastern anglers would find that they are close in looks and behavior to the Quill Gordons. The female is called the Pink Lady. This hatch is best imitated with a wet fly because the duns hatch on the bottom or between the bottom and the surface. They do not hatch on the surface. They will float down the streams in the cold water for a few feet before departing the water and they trout will take some from the surface very aggressively even in the colder water. Most anglers prefer a dry fly imitation and the dry imitation of the dun will work most of the time, just not as effectively as the wet fly. These mayflies usually hatch in the late afternoon. These are our "Perfect Fly" imitations. Notice the wet fly emerger.
March Browns, or Rhithrogena species, hatch starting around mid-July and can last until near the end of August depending on the location. You will find these in the fast water sections of riffles and runs. These mayflies hatch during the day from mid-morning until mid-afternoon but never in any large quantities. The spinners fall usually takes place in the evenings.
At the same time, the Flavs or Small Western Green Drakes start hatching in some locations. These clinger nymphs prefer the moderate water or smoother sections of the Madison River in the park. The hatch usually occurs during the late afternoon and is usually short unless the sky is overcast or cloudy. The spinner fall also occurs in the late afternoons.
Tricos hatch in the slow water sections near the park boundary close to Hebgen Lake. This hatch can last from mid-July to through September.
Callibaetis or Speckled-winged Quills will also hatch in the slow water sections near the park boundary close to Hebgen Lake. Like the Tricos, this hatch can last almost through the month of September. The spinners fall about the same time the mayflies hatch, usually in late morning.
Tomorrow I will get into the Caddisflies hatches that occur on the Madison River. They are just as, if not more important, as the mayfly hatches.
