Hatches are matched from Westfly's database of "standard" fly patterns.


Size 2-10 Woolly Bugger, Bunny Leech, Hale Bopp Leech, Possie Bugger. Black, browns, olives

Lakes; backwaters and slow sections of rivers: count-down-and-retrieve, slow retrieve, wind drift

► Size 10-12 Woolly Buggers (brown, black) or leech patterns are a standard strategy here. Cast down-and-across, then retrieve in quick, two-inch pulls with a pause between each pull. You can also team your streamer with a Prince nymph and drift the combo past rocks.


► At the beginning of June, look for a hatch of gray drakes (aka black drakes) on the upper river above Klamath Marsh. Access is tricky due to private property.

► If you're unfamiliar with the Williamson and want to catch its big rainbows, hire a guide. This is the most difficult river in Oregon to fly fish well. Fish often hang out around structure, and unlike most rivers you can't spot that structure from the surface clues. A guide can save you a lot of frustration and get you access through private property.

► If the weather is hot, we could see Hexagenia hatches in the slower water below Chiloquin near the end of June, but this hatch doesn't usually start until early July.

► Not many fish move out of Klamath Lake and into the Williamson until early July, but if we have an extended hot spell, they might start upriver in late June. The Williamson's resident trout can top 20 inches, however, and that should be enough to get the interest of most anglers.
