Deschutes River Report – May 12, 2026: Salmonfly Hatch Hits Full Stride from Maupin to Warm Springs
Chubby Chernobyl, Stimulator, Elk Hair Caddis, Parachute Adams, Pheasant Tail Nymph, Copper John, Woolly Bugger
Deschutes River Fishing Report — May 12, 2026
Lower Deschutes | Maupin Area | Above & Below Sherars Falls
The moment Central Oregon fly fishers wait all year for is here. The Salmonfly hatch on the Lower Deschutes is firing in full swing from Trout Creek downstream through Maupin, and with a forecasted high of 90°F today (Tuesday, May 12), the hatch front is expected to push all the way up to the Warm Springs boat ramp by mid-week. Golden Stoneflies and Yellow Sallies are also active alongside the big bugs, making this one of the most exciting multi-hatch windows of the season.
Current Conditions
- Flow: 3,860 CFS (USGS Gauge 14103000 – Deschutes at Moody, 5:45 AM PDT)
- Water Temp: 60°F (15.4°C) — ideal for active fish and hatch activity
- Clarity: Clear — the dam-controlled lower Deschutes is running clean despite spring flows
- Overall Conditions: Excellent
Flows are running at a healthy spring level. The river is pushing water but remains very fishable throughout the canyon. Wading anglers should use caution in faster pockets and stick to known safe crossings.
What's Hatching
Salmonflies (Pteronarcys californica) are the headline act — these prehistoric-looking giants are emerging and flying bank-to-bank through the Maupin section. Golden Stoneflies and Yellow Sallies are mixing in throughout the day. Expect the best surface action in the morning and evening when adults land and flutter on the water. Midday can produce explosive takes if you work tight to shaded banks and overhanging brush. Get your cast under the trees — this is side-arm, tight-loop territory.
Top Fly Recommendations
Dry Flies (go big!):
- Chubby Chernobyl (#6–8, orange/black) — the go-to salmonfly adult imitation; high visibility, floats all day
- Stimulator (#6–10, orange or golden yellow) — covers both Salmonfly and Golden Stone; fish tight to the banks
- Elk Hair Caddis (#12–14) — excellent in the evening as caddis join the mix after dark
- Parachute Adams (#14–16) — reliable mid-day searching pattern when fish go selective
Nymphs (for when they won't look up):
- Pheasant Tail Nymph (#14–16) — dead-drift through seams and runs; a constant producer
- Copper John (#14–16) — adds flash and weight; great in faster water
- Woolly Bugger (#6–8, black or olive) — swing it through deeper pools for aggressive trout and steelhead
Access Points
Primary access for the Maupin area is off US-197 at the town of Maupin itself, with wade fishing below the city park and boat launches at Maupin City Park and Harpham Flat. The Heritage Landing takeout below Sherars Falls offers good access to the gorge section. Above Sherars Falls, Sandy Beach and Trout Creek launch are prime entry points for the upper canyon float. Note: The river has been crowded — expect company on popular runs. Weekday fishing will be noticeably better than weekends during the hatch.
Hazards & Notes
Sherars Falls remains a mandatory portage — do not attempt to run it. Flows at 3,860 CFS make wading challenging in mid-river; stay in slower edges and back-channels. Native steelhead rules apply — all wild steelhead must be released unharmed. Please respect spawning redds.
