Hatches and Trout Flies for Smith River
The hatches on the Smith River are as varied as the fishing conditions and diversity of the
water in its hundred mile plus course. As with almost any western trout stream, the
Blue-winged Olives are important and hatch twice a year. These little mayflies start
hatching in the later part of March and last through the month of May. They hatch again
starting around the middle of September and last through October.

One of the most praised hatches on the Smith River are the Salmonflies. These large
stoneflies start hatching around the middle of May. They last until about the middle of
June but can string out to near the first of July depending on the weather and the part of
the river you are fishing.

About the first of June you will also find hatches of Golden Stoneflies. They can last to
near the end of June. Remember, both of these stoneflies are more common in the riffles
or run sections of the river.

There are also hatches of Little Yellow Stoneflies. These take place from about the middle
of June until the end of July depending on the section of the river you are fishing.

Pale Morning Duns are another important aquatic insect. These little mayflies can hatch
from about the first of June through the month of August, depending on the section of

Brown Drakes inhibit the pools and the more moderate sections of the stream. They can
hatch from about the first of June for most of the month.

There are Tricos hatches that occur in the slower parts of the river from about the first of
August through September and into the first of October.

Caddisflies are very plentiful on the Smith River. There are several species of them but
the most prevalent are the Spotted Sedges. Different species of these caddisflies hatch
from May through September.

There are isolated hatches of Little Black Caddis, or Brachycentrus caddisflies, that occur
in late April and early May, depending on the weather. Little Short-horned Sedges are
plentiful during June and July.

Green Sedges hatch during June and July and into August. These are mostly found in the
fast water sections of the river. Make sure you have some Rock Worms.

The large October Caddis hatch from about the middle of September through the middle
of October depending on the section of the river.

Streamers are very important flies to have with you any time on the Smith River. They
work best early in the morning and late in the day near dark but also, anytime the water is
high or slightly off color. The river has plenty of sculpin and minnows for the trout to eat.

Terrestrials may be the most important of all insects. They start showing up in large
quantities around the first of July and last until the end of September. Grasshoppers are
very plentiful due to the large ranches and farms surrounding the river throughout its
length. Imitations of ants and beetles are also plentiful. You may encounter some flying
ants but predicting when, is next to impossible. August would be the best chance to find
the water covered with them but you should carry some flies anytime during the summer.
