What to Expect in March

Blue-winged olive
October caddis
Golden stonefly

Hatches divided by half-month.
 Super    Major    Minor    Slight    None


As we get into the longer daylight and warmer days of March, you can expect more consistent hatches of blue-winged olives . Look for them around 1:00-1:30 (standard time). If they're hatching, toss a size 18 olive Sparkle Dun or Parachute Baetis .

Pre-hatch, try a stonefly nymph dead-drifted near the bottom, or (better) a two-fly rig with a stonefly nymph on the point and a Pheasant Tail Nymph or red Serendipity on a dropper.

Look, too, for Cinygmula mayflies. They hatch this time of year, and can be matched with a size-16 cream-colored Sparkle Dun . See Cinygmula Mayflies for details of this mayfly.

If you see big orange caddis flying around, don't assume you overslept and that it's now fall again. The Metolius sees some silver stripe caddis (an October caddis cousin) in the spring. Carry a few big, orange dry flies in size 8 with you, but pupa patterns, such as the Bird of Prey (available at The Fly Fisher's Place) work best.

March browns hatch here, too, if the weather is mild this month. But before you tie on a March brown imitation, make sure the trout are actually taking them. Just because it's hatching, it doesn't mean the trout care.

Midge hatches are still a factor in March. Red Serendipities and other pupa/larva pattern should be in your box. Watch hatches carefully: what you may think is a blue-winged olive hatch may actually be midges. Carry some Griffiths Gnats as well as Sprout Midges for a dry fly option.

With more daylight, anglers can fish longer and may run into some evening events. Look for size-16 caddis and falls of blue-winged olive spinners as dusk approaches.

Bull trout are still active. Target them now before they migrate to Lake Billy Chinook.
