Hatches and Trout Flies for the McKenzie River Oregon

The first mayfly that hatches at the beginning of a new year on the McKenzie River is the
Blue-winged Olives. These are mostly
baetis species. These hatches take place in January,
February and March. These mayflies also hatch late in the year during September, October,
November and December. January and February also has hatches of Little Winter Stoneflies.

Trout can be taken on imitations of midges on the McKenzie River throughout the year but are
more popular during the times the water is cold and few other aquatic insects are hatching.

March Browns hatch during the month of March starting about the middle of the month. This
hatch usually last about a month and a half, depending on the area of the river. Brown
stoneflies also begin to hatch in March. They are present until the first of second week of April.
Little Short-horned Sedges or caddisflies hatch from the last of April into the first of
August,depending on the section of the river your fishing.

Golden stoneflies start showing up in April on the McKenzie River. They are usually present up
until about the first or second week of July. Little Yellow Stoneflies also start hatching this
month. You will find different species from April into the month of August. Many anglers call
these Yellow Sallies.

PMDs or Pale Morning Duns start hatching around the first of May. These little mayflies hatch
up until August, depending on the section of the river you are fishing. Green Sedges or
caddisflies will hatch in April. This hatch last until about the first of June. The larvae of these
caddisflies, imitated by the Green Rock Worm, will take trout all year.

Spotted Sedges, or caddisflies, hatch on the McKenzie River from May through the month of
August. These are the largest of the caddisfly hatches and consist of several species that are
almost identical.

Salmonflies start hatching in late May. These large stoneflies will continue to hatch untill about
the first of July, depending on the section of the river you are fishing. Yellow Quill mayflies
hatch during June and July. Pale Evening Duns hatch in July.

October Caddis hatch in September and October. These are rather large caddisflies.

Don't overlook the terrestrial insects. They can be very important during the summer and early
fall months of the year. Imitations of grass hoppers, ants, and beetles all catch trout. The
terrestrial season starts in June and last through the month of September.

Streamers are very important flies to have with you anytime of the year fly fishing the McKenzie
River. Those that imitate sculpin are usually very effective. Others should imitate baitfish and
minnows. These will come in very handy anytime the water is stained from rain or melting snow.

Fish eggs are an important form of food below Leaburg Dam. Salmon eggs are in the
river during November and December. Flies imitating these eggs are very effective as well as
other traditional steelhead flies.

We recommend our own "Perfect Flies", of course, but not because they are ours. Its because
they are the best flies you can buy. They imitate specifics insects at all the stages of their life
trout feed on. They are highly effective when used properly. If you haven't already tried them,
we suggest you do. You won't be disappointed.
