Weekly AI Outlook as of 07/31/26
Flow is reading 518 cfs on the Metolius — notably below the historical summer norm of 1,200–1,600 cfs cited in the seasonal outlook, which is worth watching. At 58.5°F, water temps have climbed well above the spring creek's typical 46–50°F baseline, crossing the PMD trigger threshold and pushing toward the upper comfort range for bull trout. With a 91°F high forecast today before a break to the low-to-mid 70s through the weekend, early mornings and evenings are your windows — fish will be stressed midday. PMDs are in peak emergence; expect activity mid-morning into early afternoon on this spring system. Rhyacophila caddis should fire at dusk. Fly Fisher's Place had a recent report but no specific pattern intel was provided — outfit accordingly with PMD Comparaduns and Sparkle Duns #16–18, and an X-Caddis or Elk Hair Caddis #16 for evening. No recent shop intel with tactical detail — outlook based on current conditions.
- Flow: 518 cfs as of 7/31 — well below typical summer levels of 1,200–1,600 cfs. Lower flows mean flatter, clearer water; long leaders and precise presentations required.
- Hatches: PMDs (peak month) active mid-morning to early afternoon. Caddis (Rhyacophila) at dusk. PMD Comparadun/Sparkle Dun #16–18; X-Caddis #16 for evening.
- Water Temp: 58.5°F — above this spring creek's normal 46–50°F baseline. PMD threshold crossed; bull trout thermal stress a concern during today's forecast 91°F high.
- Best Window: Early mornings and evenings. Avoid midday during today's 91°F forecast. Cooler days Sat–Mon (70s) may extend productive windows through the afternoon.

About this Water
- Spring Creek
- Best months: Apr–Oct, peak May–June (Green Drake)
The Metolius River in central Oregon springs full-formed from the base of Black Butte and runs cold and crystal-clear through old-growth ponderosa pine country. The water is famously beautiful — dense aquatic vegetation, gravel runs, and the kind of clarity that exposes every angler's mistake. Native bull trout and redband trout are the wild residents, supplemented by stocked rainbows in some reaches. The river is fly-only above Bridge 99 and demands long leaders, fine tippets, and patient stalking. Hatches are subtle and continuous: midges, BWO, golden stones, and the famous Green Drake emergence in late spring.
The Metolius emerges from the ground at over 50,000 gallons per minute — one of the largest single-source springs in the United States — creating a river that runs at 48°F year-round regardless of air temperature or season.
January Outlook
The Metolius is one of the few rivers that is genuinely fishable in January — its constant 46–50°F spring-fed temperature never fluctuates. Midges and Baetis nymphs produce fish even in the coldest Oregon winters.
Productive Patterns
- Zebra Midge
- RS2
- Baetis Nymph
- Soft Hackle Midge
Tips
Winter on the Metolius is quiet and beautiful. The Camp Sherman area stays accessible. Midge pupa fishing in the slower pools between the campgrounds. The river looks the same in January as August — remarkable consistency.
Water Notes
Constant 1,200–1,600 cfs. Water 46–50°F year-round. Never freezes. The most thermally stable river in Oregon.
February Outlook
February midges and early Baetis on the Metolius. The spring-fed constant temperature keeps fish active through the winter.
Productive Patterns
- Zebra Midge
- Baetis Sparkle Dun
- RS2
- Soft Hackle Emerger
Tips
February on the Metolius is excellent for the dedicated angler willing to brave cold air temps. The water stays 46–50°F regardless. Focus on the flat sections near Camp Sherman for midge activity on sunny afternoons.
Water Notes
Constant 1,200–1,600 cfs. Water 46–50°F. Air temps cold but water never changes. One of Oregon's finest winter fisheries.
March Outlook
March on the Metolius brings the first significant surface activity. Early Baetis and midge hatches produce rising fish on warm afternoons in this unique spring-fed Oregon river.
Productive Patterns
- Baetis Sparkle Dun
- Midge Dry
- RS2
- Soft Hackle
Tips
March is when the Metolius begins showing its spring creek character. The first consistent afternoon rises of the year. Fish the Camp Sherman flats in the afternoon when Baetis begin hatching. The fish here see everything — leaders to 12 feet and 6X tippet minimum.
Water Notes
Constant 1,200–1,600 cfs. Water 46–50°F. Spring creek precision required year-round.
April Outlook
The Metolius is a unique spring-fed river that emerges from the base of Black Butte fully formed. Cold, clear, and full of large, educated redband rainbows.
Productive Patterns
- Callibaetis Sparkle Dun
- Elk Hair Caddis
- Midge Pupa
- Soft Hackle
Tips
The Metolius requires patience. The fish are notoriously selective — spring creek-level presentations in a spring-fed river environment. The Camp Sherman area is the most accessible.
Water Notes
Constant spring-fed flows 1,200–1,600 cfs. Water a constant 46–50°F year-round. Never subject to runoff or drought.
May Outlook
PMD and Caddis hatches join the Metolius program in May. One of Oregon's most technical rivers coming into peak season.
Productive Patterns
- PMD Sparkle Dun
- Elk Hair Caddis
- Pale Evening Dun
- Soft Hackle Emerger
Tips
May is the Metolius transition from early-season midges to the full PMD and caddis program. The river sees more anglers now — arrive early for the best pools near Camp Sherman. Evening caddis produce rising fish from 6–9pm.
Water Notes
Constant 1,200–1,600 cfs. Water 46–50°F constant. Spring hatch season building.
June Outlook
The Metolius in June with Pale Evening Dun hatches and Caddis. The evening hatches draw large redbands to the surface.
Productive Patterns
- Pale Evening Dun
- Elk Hair Caddis
- PMD Cripple
- Soft Hackle Emerger
Tips
The Metolius is a sanctuary for technical fly fishers. Fish are large, educated, and in constant, stable current. Long leaders and precise presentations are mandatory.
Water Notes
Constant 1,200–1,600 cfs. Water 46–50°F constant. One of the coldest summer rivers in Oregon.
July Outlook
Excellent summer fishing on the Metolius. The constant 48°F temperature makes it a thermal refuge for trout in the summer heat.
Productive Patterns
- Callibaetis
- PMD Cripple
- Elk Hair Caddis
- Ant
Tips
The Metolius is at its most valuable in summer — a cold, clear spring river in the middle of hot, dry Oregon. Fish the flat sections between the campgrounds for the most consistent action.
Water Notes
Constant 1,200–1,600 cfs. Temperature an incredible 46–50°F even in August. A genuine cold-water refuge.

Productive Patterns
- Elk Hair Caddis
- Callibaetis Sparkle Dun
- Ant
- Soft Hackle
Tips
Escape the summer heat at the Metolius — the camp sites fill on weekends but the fishing pressure is spread across miles of river. Fish the sections between the campgrounds for the most consistent action. Evening caddis is excellent.
Water Notes
Constant 1,200–1,600 cfs. Water 46–50°F — remarkable in August. The Metolius is Oregon's top summer heat refuge for trout.

Fall Baetis hatches on the Metolius. The river fishes consistently through all seasons.
Productive Patterns
- Blue Winged Olive
- Elk Hair Caddis

Tips
October is the Metolius at its least pressured and most productive. Reliable BWO hatches on overcast afternoons. The redband rainbows are in peak condition. Camp Sherman in fall is a special experience.
Water Notes
Constant 1,200–1,600 cfs. Water 46–50°F year-round. Fall foliage around the Cascade camp area is beautiful.
November Outlook
November returns the Metolius to solitary fishing. Midges and late Baetis produce fish year-round in this remarkable spring-fed Oregon river.
Productive Patterns
- Zebra Midge
- Blue Winged Olive
- RS2
- Soft Hackle Midge
Tips
The Metolius in November is quiet and productive. The constant temperature means fish never go dormant. Midge fishing in the pools and Baetis hatches on mild afternoons. Camp Sherman is peaceful and mostly empty.
Water Notes
Constant 1,200–1,600 cfs. Water 46–50°F. The spring-fed river looks identical to summer. One of the most consistent winter fisheries in the Pacific Northwest.
December Outlook
December winter fishing on the Metolius is genuinely productive — the constant spring-fed temperature keeps fish active all year. Midges and midge pupa are the primary patterns.
Productive Patterns
- Zebra Midge
- RS2
- Midge Pupa
- WD-40
Tips
The Metolius is one of the only rivers where December fishing is indistinguishable from June in terms of river conditions. The cold air is offset by the never-changing water. A bucket-list winter trip for dedicated technical fly fishers.
Water Notes
Constant 1,200–1,600 cfs. Water 46–50°F year-round. December is exceptional — conditions identical to summer.
