Planning Your Fly-fishing Trip To Yellowstone
...........................  ......................Fly Fishing Yellowstone National Park

When to Come and What To Expect:

Fly Fishing: Yellowstone National Park - July - Grayling Creek

Grayling Creek is a little sleeper trout stream that everyone that drives by on their way
to fish the Gallatin River. It is located along the #191 highway North of West
Yellowstone. Several miles of the stream can be accessed from the road. It doesn't
contain the largest trout in Yellowstone Park, but it probably contains as many as any
other stream there. The stream flows into Hebgen Lake.

Most of the trout are cutbows, or a mixture of rainbow and cutthroat trout, but you may
also catch some rainbows and cutthroats. If it were not for the Gallatin River not far
from Grayling Creek, probably everyone would stop to fish its waters. It is usually clear
and warm enough to fish by the end of June or the first week of July.

The fish probably only average 6 to 12 inches, but there are some larger. You will
usually find them around the many undercut banks. When the water first clears you will
find a variety of aquatic insects that will start to hatch including Pale Morning Duns and
Blue-winged Olives. Stoneflies will begin to hatch the first of July. There are plenty of
Yellow Sallies, or Little Yellow Stoneflies, and even some Golden Stoneflies that hatch
in the stream.

Caddisflies will become more plentiful as the month goes by including species of
Spotted Sedges, Little Short-horned Sedges and Green Sedges. The evening caddis
egg laying activity usually turns the trout on good, provided it is warm. The temperature
will begin to drop fast each day in July as soon as the sun hits the horizon.
