Weekly AI Outlook as of 06/05/26
The McKenzie is running 2090 cfs at 52.5°F — ideal flow for wading and drifting, with water temps just hitting the sweet spot for caddis emergence. No recent shop intel — outlook based on current conditions. With caddis peak season in full swing, focus midday emergence windows when Hydropsyche start moving. The weekend's warming trend should trigger strong afternoon hatches before Monday's heavy rain potentially muddies things up.
- Flow: 2090 cfs — perfect wading flow, boulder gardens accessible, back eddies holding fish without dangerous current
- Hatches: Peak caddis month with water at 52.5°F triggering Hydropsyche emergence. Elk Hair Caddis #16, X-Caddis, Soft Hackle patterns
- Water Temp: 52.5°F — crossed the caddis threshold, approaching Golden Stone temps (55°F). Prime zone for afternoon emergence activity
- Best Window: Midday through afternoon as air temps climb to mid-60s Saturday. Monday's 1.5" rain could change everything by Tuesday

About this Water
- Freestone
- Best months: May–Oct, peak Sept–Oct (October Caddis)
The McKenzie River in western Oregon is the birthplace of the McKenzie River drift boat — the design that defined modern western fly fishing transport. The river runs cold and clear out of the Cascades through old-growth Douglas fir country, supporting wild redband rainbow trout and a robust population of native cutthroat and bull trout. The water is technical: small, fast, and demanding precise mending and presentation. October Caddis in fall produces the most exciting dry-fly fishing of the season.
The McKenzie River drift boat — a flat-bottomed wooden craft with a high prow and stern — was developed on this river in the 1930s and remains the iconic vessel of western fly fishing.
January Outlook
January on the McKenzie is the winter off-season. High flows from Cascade rain and snow swell the river. The upper McKenzie above the hatchery holds resident rainbow trout in the slower pools. The Willamette Valley setting is quiet.
Productive Patterns
- Midge Nymph
- Soft Hackle
- Baetis Nymph
- Small Streamer
Tips
Winter McKenzie fishing is quiet — the summer drift boat crowds are gone. Resident rainbows in the slower pools near the campgrounds. The upper sections above Leaburg Dam are most accessible for winter wade fishing.
Water Notes
3,000–8,000 cfs. Water 42–48°F. High winter flows. Resident trout fishing in slower sections.
February Outlook
February McKenzie fishing continues in winter mode. Flows often remain high from Cascade snowmelt and Oregon Cascades rain. Midges and Baetis nymphs on mild afternoons.
Productive Patterns
- Midge Pupa
- Baetis Nymph
- Soft Hackle Emerger
- Woolly Bugger
Tips
The upper McKenzie above Blue River provides access to smaller-water resident trout fishing in February. The main river above Leaburg remains high — focus on the headwater sections for quieter conditions.
Water Notes
2,500–7,000 cfs. Water 42–48°F. Cascade snowmelt and rain. Upper sections most fishable.
March Outlook
March brings the first Baetis activity to the McKenzie. Flows begin dropping toward prime as spring progresses. The river corridor is beautiful with spring greens emerging in the Cascade foothills.
Productive Patterns
- Baetis Sparkle Dun
- Elk Hair Caddis (small)
- Soft Hackle
- Midge Dry
Tips
Late March can be excellent on the McKenzie when flows drop after a dry spell. The upper sections near Leaburg come into shape first. Early Skwala activity may appear in the section below the hatchery.
Water Notes
2,000–5,000 cfs. Water 44–52°F. Flows dropping. Early hatches beginning.
April Outlook
April spring fishing on the McKenzie. Golden Stone hatches begin in April and flows are typically dropping toward ideal float conditions.
Productive Patterns
- Golden Stone (small)
- Elk Hair Caddis
- PMD Sparkle Dun
- Soft Hackle
Tips
April is when the McKenzie begins its transformation from winter river to prime float river. The first Golden Stone activity in the upper sections. Float trips from Finn Rock down become possible as flows moderate. Local drift boat operations are booking up.
Water Notes
1,500–4,000 cfs. Water 48–56°F. Spring conditions with Golden Stone activity building.
May Outlook
The McKenzie River in Oregon is prime May fishing with Golden Stones and Caddis. The upper McKenzie above Leaburg Dam is the best section.
Productive Patterns
- Golden Stone
- Elk Hair Caddis
- PMD
- Stimulator
Tips
The McKenzie drift boat (designed for this river) is the classic way to fish it. Float from Leaburg to Armitage Park for the best experience.
Water Notes
2,000–5,000 cfs in May. Drops to fishable by late May. Water 50–58°F from Cascade snowmelt.
June Outlook
Peak season on the McKenzie. Golden Stone, Salmonfly, Caddis — the McKenzie's hatches are among the finest in Oregon.
Productive Patterns
- Salmonfly #4
- Golden Stone
- Elk Hair Caddis
- Stimulator #8
Tips
Float the upper McKenzie from Leaburg Dam upstream in early June for the Salmonfly. The canyon sections are spectacular and the rainbow trout are aggressive.
Water Notes
1,000–3,000 cfs. Water 52–60°F. The McKenzie is a classic Oregon float river.
July Outlook
Excellent hopper-dropper and evening caddis fishing. The McKenzie's classic wooden drift boats are ubiquitous in summer.
Productive Patterns
- Hopper-Dropper
- Elk Hair Caddis
- PMD Cripple
- Royal Wulff
Tips
Float the McKenzie for the full experience. The evening caddis hatch is outstanding. The river runs clear and cold from its Cascade headwaters.
Water Notes
800–2,000 cfs. Water 56–64°F. Classic Oregon summer float conditions.
August Outlook
August hopper-dropper and caddis fishing continues on the McKenzie. The Cascade-fed water stays cooler than lowland rivers. Evening caddis hatches are excellent.
Productive Patterns
- Hopper-Dropper
- Elk Hair Caddis
- Stimulator
- Dave's Hopper
Tips
The McKenzie stays relatively cool from its Cascade Lava Lake source even in August. Float from Leaburg to Armitage for the best access. Fish the bank edges for hopper action and the evening pools for caddis.
Water Notes
600–1,500 cfs. Water 58–65°F. Good summer conditions. Cascade-fed source keeps temperatures moderate.
September Outlook
Fall fishing on the McKenzie with BWO hatches and the beginning of coho and Chinook salmon runs in the lower sections.
Productive Patterns
- Blue Winged Olive
- Elk Hair Caddis
- Mahogany Dun
- Hopper
Tips
September on the McKenzie is excellent for rainbow trout with less pressure than summer. The BWO hatch produces consistent action from 1–4pm.
Water Notes
600–1,500 cfs. Water 52–60°F. Good fall conditions.
October Outlook
Fall coho and Chinook salmon enter the McKenzie below the hatchery at Leaburg. BWO hatches produce excellent resident trout dry fly fishing throughout the upper river.
Productive Patterns
- Blue Winged Olive
- Mahogany Dun
- Coho Streamer
- Egg Pattern
Tips
October on the McKenzie is excellent — fall salmon in the lower sections and resident trout dry fly fishing in the upper reaches. The BWO hatch on overcast afternoons is reliable. Float from Leaburg down for both species.
Water Notes
700–2,000 cfs. Water 50–58°F. Fall salmon running and resident trout BWO season. Outstanding variety.
November Outlook
November on the McKenzie brings fall steelhead into the hatchery sections and resident rainbow trout continue in the upper river. Flows increase with the first Cascade rains.
Productive Patterns
- Soft Hackle
- Egg Pattern
- Blue Winged Olive
- Midge Nymph
Tips
November McKenzie fishing includes both resident rainbow trout in the upper river and hatchery steelhead below Leaburg. Check ODFW regulations for the hatchery steelhead fishery. Late BWO activity on mild afternoons is possible.
Water Notes
1,000–3,500 cfs. Water 46–54°F. Fall conditions with increasing rainfall. Hatchery steelhead and resident trout.
December Outlook
December returns the McKenzie to winter conditions. Flows increase significantly with Cascade rain. Resident rainbow trout in the upper sections and late steelhead in the lower river.
Productive Patterns
- Midge Nymph
- Egg Pattern
- Soft Hackle
- Small Streamer
Tips
December fishing on the McKenzie requires picking good weather windows between winter storms. The upper sections above the Fin Rock area provide the most sheltered winter access. A good alternative to the coast rivers when those are blown out.
Water Notes
2,500–7,000 cfs. Water 42–48°F. Winter flows building. Upper river most fishable.
