Clay and I floated the lower Mckenzie on into the Willamette, from Armitage to Cross Roads ramp this Tuesday. Fish were rising from the start of our float around 10am. I had to pry the indicator rod from Clay’s hands and quickly insert the Sage Circa 589-4, after that it was all dry all day. We did a little swinging of flies but by far our best luck was with dry flies. Caddis flitted about from the start, and as the sun won out over cloud cover the caddis grew thick. We stopped on numerous riffles with fish up and feeding. Best paterns were Parachute Adams, Purple Rooster, March Brown Parachutes and Peacock Caddis. As the sunshine of Tuesday afternoon intensified so did the caddis hatch. The caddis hatch became so intense in spots that we moved away from the spot in search of fewer bugs and less selective fish.
The weather looks to have shifted into clouds and showers for the next week or so, a perfect storm for the angler in my mind. With low snow pack and low reservoirs in the Willamette Valley water conditions are likely to remain ideal despite rainfall. Warm rainy days are without question the very best for March Brown hatches. The adult and emerging insect becomes “stuck” in the film and on the surface much longer, giving the fish a great opportunity to eat them. The Caddis that have hatched and will also be available but not as intense as on bright warm days. Fishing will be excellent!
