Winter Baetis Hatches Dry fly sight-fishing at its best.
Baetis Nymph Baetis Soft Hackle Baetis Surface Emerger
Baetis mayflies are an extremely widespread genus.  Several species  are multi-brooded and may have two or more generations  per season.  There are at least five sub-species that hatch from Oregon streams and lakes.  Hatches can occur nearly any time of year.  This makes them common trout food and therefore very important to fly anglers.  Baetis are found in both the western and  eastern United States.  The Latin name is the popular name used by the angling public. They are also commonly called  blue-winged olives.  However Baetis can also have tan or gray bellies.  Trout can be very selective and prefer one shade over another.  Most Baetis look gray on the water and can be quite deceptive.  It pays to catch a hatched insect and examine it closely under magnification.  Baetis are small, #16–20, but they hatch in big numbers.  The best hatches occur on over-cast, rainy days.  Hatches can start in late morning and extend into early after noon.  
Baetis nymphs are swimmers.  They inhabit many water types in streams, but prefer weedy riffles and runs.  Use a "kick screen" in the morning.  If you find Baetis nymphs with wing pads that are very dark, chances are there will be a hatch during that day.  Nymphs will start getting restless in the morning.  This is a good time to pound the bottom with Baetis Nymph patterns.  Nymphs start drifting down the river and swimming to the surface in the late morning.  Some nymphs might make several attempts to reach the surface before they actually make it.  These insects are very small and don't provide much food value unless they can be taken easily in a large quantity. The best places to fish are where riffles with small graveled weedy runs enter slow pools or slow back-eddies.  The nymphs leave the bottom of the riffle and drive along the bottom for a distance.  Then they attempt to swim to the surface while the water velocity slows down. When the nymphs reach the surface of the water, their wing pads break through the meniscus.  They can hang there for several minutes as floating nymphs.  As the skin splits down the back of the head and between the wing pads the dun starts to emerge through this tear. At this point the insect can neither swim nor fly.  It is completely helpless and a perfect target for trout. The hatching duns can collect in quieter flows in very large numbers.   The trout know where these conditions regularly occur and also collect in large numbers.  Feeding is usually slow and quiet.  Look for snouts and fin tips.  Target individual fish with pin-point casting.

Stable Isotopes Resolve the Drift Paradox for Baetis Mayflies in an Arctic River
By: Anne E. Hershey, ­John Pastor, ­Bruce J. Peterson, and ­George W. Kling­

The colonization cycle hypothesis states that stream ecosystems would become depleted of insects if flying adults did not compensate for drifting immatures. Using long—term drift and benthic abundance data, we show that a Baetis mayfly nymph population moves downstream during development in the Kuparuk River in arctic Alaska. Baetis relative benthic abundance decreased from early to late season in an upstream unfertilized river section, while simultaneously increasing in the downstream fertilized section. Baetis nymphs drifted significantly more in the upstream unfertilized section, compared to the downstream fertilized section where food was more abundant. Approximately one—third to one—half of the nymph population drifted at least 2.1 km downstream during the arctic summer. A stable isotope tracer experiment and mathematical models show that about one—third to one—half of the adult Baetis population flew 1.6—1.9 km upstream from where they emerged. These results provide a quantitative test of the colonization cycle for the dominant grazer/collector in the Kuparuk River. Quantifying the colonization cycle is essential to understanding stream ecosystem function because offspring of downstream insects are needed for nutrient cycling and carbon processing upstream. Since downstream drift and upstream flight are important components in recovery of streams from disturbances, our results provide a quantitative method for predicting recolonization rates from downstream, essential to estimating recovery.

Baetis Nymph
Baetis nymphs are swimmers.  They prefer weedy riffles and runs.  Use a "kick screen" in the morning.  If you find Baetis nymphs with wing pads that are very dark, chances are there will be a hatch during that day.  Nymphs will start getting restless in the morning.  This is a good time to pound the bottom with Baetis Nymph patterns.  Tied for the winter hatch.

Baetis Soft Hackle Baetis Soft Hackle
Some winter Baetis start to emerge below the surface of the water and others get hung up in the shuck and are still-born.  Still others get swept into fast water and are pulled back under by the currents and drown.  Fishing a soft hackle replica in the surface film on a slack line can fool some of the pickiest feeders.
This pattern is tied for the winter hatch. It is a Mark Bachmann pattern tied by FLYH2O.

Baetis Surface Emerger
Winter Baetis Mayflies can be very dark colored.  Many are jet black.  As the nymph swims to the surface he adult insect is already separating itself from the nymphal shuck.  Bright green bands form at each abdominal segment.  As the skin splits down the back of the head and between the wing pads of the nymph, the dun starts to emerge through this tear.   At this point the insect can neither swim nor fly.  It is completely helpless and a perfect target.

Rick Hafele and Dave Hughes burst on the scene in the 1980's with their ground breaking book, "Western Hatches". Rick & Dave have devoted much time to understanding and matching the hatches that nourish resident trout west of the Rocky Mountains. Their works are on-going, and will last forever in the annuls of scientific understanding of invertebrate fauna.
Hafele & Hughes are two names that go together like bugs and water!

In their first book together since their 1981 classic Western Hatches, aquatic entomologist Rick Hafele and fly fishing author Dave Hughes, combine their extensive knowledge to describe in detail the widespread and diverse western mayflies, unraveling their mysteries, revealing how to identify them, how to match them, and how to fish their imitations.

Researched, written, and photographed over a period of more than twenty years, Western Mayfly Hatches covers all mayfly hatches important in the entire range of western states and provinces.  Color photos reveal the important aspects of each stage of each important mayfly hatch.  Scientifically accurate illustrations by artist Richard Bunse depict the details that will allow you to recognize key differences between species for both nymph and adult stages.  A series of fly patterns, from suggestive through impressionistic to imitative, are listed for each stage of each hatch.  The full dressing is given for each fly, and each is photographed in color by Jim Schollmeyer.

    Also included is information on collecting and observing mayflies, mayfly behavior and natural history, fly-tying techniques, presentation methods for nymphs, emergers, duns, and spinners, plus much more.  Unique "hatch ranking tables" list the important aspects of each hatch, and provide a means for determining its importance relative to all other hatches.  Hatch charts show graphically the emergence period of each hatch throughout the year, and the time of day you might encounter the insect on the water being fed upon selectively by trout.

    Includes more than 350 color photographs, 75 illustrations, and more than 175 fly patterns, You'll be amazed how much information you'll discover within the pages of this book.  Western Mayfly Hatches leaves no stone unturned.

Monster Muskie
Muskellunge are the largest member of the pike family, Esocidae. The name comes from the Ojibwe word maashkinoozhe, meaning "ugly pike", by way of French masque allongé.
More information on Muskellunge (Muskies) is available on Wikipedia.
Look at that big fly. So you think some of our west coast steelhead flies are big, just take a look at that giant fly hanging from the muskie's mouth. This 50"+ fish was caught by Nick Pujic, manager of
The Canadian Fly fisher Magazine from Moira River in Eastern Ontario. He used a Sage 1090-4 Xi2 rod and the fight lasted about five minutes. Any musky on a fly is an accomplishment; they don't call them the fish of 10,000 casts for nothing!  Nick's Muskie is the fish of several lifetimes over.
