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


Size 14-16 Pheasant Tail. Brown


Size 14-16 Quigley Cripple, Film Critic, Hackle Stacker. Gray to tan

Lakes, slow water: chuck-and-sit


Size 14-16 Sparkle Dun, Hairwing Dun, Adams, Comparadun. Gray to tan

Lakes, slow water: chuck-and-sit

► Callibaetis get smaller and darker as the season progresses, so size 16 flies will be needed.

► Look for late-morning to mid-afternoon hatches.

► Trout will feed on active nymphs for several hours before the hatch. Take advantage of this by casting a Flashback Pheasant Tail and retrieving it ever so slowly with an intermediate line and a leader of at least 12 feet.

Callibaetis hatches will continue throughout the month, but August hatches are typically weak; they pick up again in September.


Size 8-16 Soft Hackle, . Body: black, brown, white; Shroud: tan

Lakes; backwaters and slow sections of rivers: verticle retrieve, slow retrieve


Size 10-16 Elk Hair Caddis, Parachute Caddis, X Caddis. Body: black, brown, white, cream

Lakes; backwaters and slow sections of rivers: chuck-and-sit

► These caddis are recognizable by their very long antennae. Evening hatches may occur. Try a size 8-10 Goddard Caddis.

► These caddis are recognizable by their very long antennae. Evening hatches may occur. Try a size 8-10 Goddard Caddis.


Size 10-22 Chans Chironomid Pupa, Zebra Midge. Black, gray, olive, red, creams, browns

► The trick is to match the size and color of the pupae (size is more important than color). When in doubt, try casting two or three flies at a time, with different size/color patterns on droppers. This lets you find out which patterns the trout prefer. Once you've got it figured out, just cast a single-fly rig.


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

► Always a good choice here.


Size 2-8 Muddler, Woolly Bugger, Clouser Minnow, Possie Bugger. Browns, olives, silver, greens

Lakes; rivers over gravel and cobble, undercut banks: count-down-and-retrieve, slow retrieve, wind drift, deep swing

Sticklebacks are common in the lake due to illegal live bait fishing by bass anglers (the bass were also an illegal introduction). So imitations can be useful.


► You can improve your odds by going to a long leader.

► Algae blooms can occur at this time of year. If you run into one, seek clearer water. This is possible in Crane Prairie due to the temperature gradient in the lake. You'll find cooler water at the inlets of the Deschutes and Quinn rivers.

► As always at Crane Prairie, a slow retrieve is productive, whether you're casting a Woolly Bugger, damselfly nymph, size 16 Pheasant Tail, stickleback imitation, or even a midge pupa.

► The Rock Creek, Cultus channel, Quinn channel, and Deschutes channel areas should improve throughout the month. Trout will probably concentrate in the channels as the water warms and drops.

► Extended periods of high pressure bring light, almost non-existent, east winds and bright days. Fishing will be poor on those days. Under these conditions, seek wind riffled water, if you can find it. Trout will be more receptive there.

Woolly Buggers and green leech patterns are always worth casting, especially near dawn or dusk.

► August is a touchy month here, as it is in most lakes. Algae blooms can be an issue. Trout will be moving into the old river channels--if they're not there already--as the water warms up and water quality declines.
