Western March Brown Mayfly Hatches

Rhithrogena morrisoni (that's the scientific name)

Western March Browns are your first "easy-to-see" hatch of the new season. Look for March Brown hatches on local rivers when water temperatures start reaching 42 degrees consistently. This can occur in most lower elevation watersheds in mid-February and continues through March and early April. Hatching March Browns can create some very exciting surface film and dry fly fishing. Hatches of duns usually start in the early after noon and spinner falls are in the late evening.

Pounding the bottom with weighted March Brown Nymph can provide constant action from mid-morning into the early stages of the hatch. The March Brown Nymph in sizes #12 & #14 will be your bread and butter fly. However nymphal color tends to adapt to the color of the stream bed. Most March Brown nymphs are dark, some are nearly black. Your catch may increase if you thin out the legs with your leader clipper and color them with a black felt marker. Fishing two flies at once will increase your odds of hooking up. Usually two different colors or sizes are used. The Guide's Choice Hares Ear is a valuable pattern to have with you, and will some times out fish the more realistic patterns. Most March Brown Nymphs are fairly skinny #14's, but slightly larger flies can also work. March Brown nymphs live in riffles and fast, rocky runs. As the nymphs near maturity, they migrate to slower water. During the migration, they can loose their grip and drift in the current. For this reason trout will congregate in places where fast riffles start to slow down and on the seams between the fast and slow water. Fish your nymphs where the current changes speed. Approach the water carefully. Start by fishing the slower water first with flies that are lightly weighted. Your flies will be most effective if they are perfectly dead drift. Cast them slightly upstream and mend a little slack into you presentation. As you work your way out into the faster current, add lead shot to keep your flies near the bottom.

As the water warms at mid-day the nymph rise toward the surface to hatch. Some of these nymphs are intercepted by trout during this upward migration. Try tying a March Brown Soft Hackle to a dropper 3' above your nymphs. This technique can pay extra dividends. Swinging soft hackle emergers during the early stages of the hatch can also be deadly effective and lots of fun.

As the Duns begin to hatch, trout will rise to the surface to catch them. This often produces the most visually exciting part of the day. Big trout rising to March Browns during the peak of the hatch can be very splashy. Often the rise starts much quieter as trout pick off the emergers just below the surface. And some duns will emerge from the shuck slightly below the surface. At this time a March Brown Soft Hackle or Flymph fished just below the surface can be your best fly. The Flymph is often even more effective if you add a March Brown Cripple or dry fly to a dropper 1' to 3' from your soft hackle and fish both flies dead drift.

March Browns and their possible related species seem to come in a variety of shades and colors. That is why there is some disagreement between anglers fishing different watershed as to what the actual colors of March Brown Duns are. The ones that hatch most often on the Sandy River are brown with mottled wings. We have seen that same fly on the Deschutes and Clackamas Rivers. On the Deschutes we have also seen spring time mottled wing mayflies the were grey wing olive. The trout like both kinds. Our friends that fish the McKenzie report March browns that are shades of gray. To be on the safe side you should carry several brown patterns, a blue wing olive parachute and a Parachute Adams in dark tones. If they are all #14 you're probably in the game.

Duns and emergers produce the best fishing, but some trout will sip spinners in the quietest of water. A March Brown "spinner fall" can extend your fishing day. Spinner falls usually occur over faster water areas. However they create the most reliable feeding activity if they raft up in back eddies down stream. Sometimes the afternoon back eddy rise that you think is midge emergence is actually created by collecting dead March Brown spinners.

Best tackle to fish a March Browns is a 9' #4 or #5 weight rod with an action that works easiest at the 20' to 50' cast range. I prefer a weight forward line that is a little on the heavy side, is a moderate color and is very clean so that it easily shoots smoothly at all ranges. The standard 9'-5X trout leader is good starting point. You might go to 4X if you get brutalized by big fish. Remember the best fly is the one that is perfectly placed in a risers feeding lane.
Have a great spring.
