Lower Deschutes River Report – May 14, 2026: Salmonfly Hatch Heating Up
Chubby Chernobyl, Stimulator, Elk Hair Caddis, Pheasant Tail Nymph, Woolly Bugger
Lower Deschutes River – May 14, 2026
The bottom line: The Lower Deschutes is fishing well heading into what should be a prime week for the salmonfly hatch. Flows are elevated but fishable, the water is warmer than average for mid-May, and the big bugs are starting to make their move to the banks. Get out this week.
Current Conditions
The USGS gauge at Moody (gauge #14103000) recorded 3,800 cfs and a water temperature of 59.7°F (15.4°C) as of early this morning — provisional data as of 5:45 AM PDT. Flows are elevated for mid-May but well within the fishable range on this big freestone river. Expect slightly off-color water in the Maupin corridor as snowmelt continues to push through. Higher water concentrates fish near the banks and in seams off main current, which actually makes locating fish more predictable when you know where to look.
Hatch Activity
The salmonfly (Pteronarcys californica) hatch is underway on the lower Deschutes. Local guides are reporting egg-laying adults and the stonefly nymph migration to the banks is in full swing. Warm water temps — 60°F is well above average for this date — point to this week being prime time for big dry fly action. Caddis are also thick right now, creating a second dry fly opportunity. PMDs and Pale Evening Duns are present but fish are not keying on them heavily yet.
Top Fly Recommendations
- Chubby Chernobyl – The go-to high-floating dry for the salmonfly hatch. Fish it big (size 6–8) near the banks and along grassy ledges where adults congregate.
- Stimulator – An excellent salmonfly and stonefly imitation; orange or red body in size 6–8. Proven producer during the hatch window.
- Elk Hair Caddis – With caddis thick on the water, a size 14–16 tan or olive EHC fished in a tandem dry rig behind a stonefly pattern is money right now. Available at bugsnjugs.com.
- Pheasant Tail Nymph – Size 14–16, dead-drifted deep. The subsurface migration of stonefly nymphs is a feast for trout, and a PTN mimics the smaller nymph forms well.
- Woolly Bugger – In olive or black, size 6–8 — swing it through the faster runs for an aggressive eat from a big lower Deschutes redband.
Pro tip: A dry-dropper rig with a Chubby Chernobyl or Stimulator up top and a Pheasant Tail Nymph 18–24" below is the most versatile setup right now. If fish are eating off the surface, stick with the dry. If not, switch to an indicator and dredge a tandem nymph rig through the deeper seams.
Best Access Points
- Maupin City Park / Harpham Flat – Classic access. Harpham Flat historically produces well during the salmonfly hatch.
- South Junction – Good access above Sherars Falls; wade-fishable at current flows from riffles and ledge water.
- Sherars Falls – Watch for active tribal dipnet fishing. Respect fishers and all restricted access zones.
- Oak Springs (below Sherars Falls) – Excellent drift-boat water; some bank access available through this canyon reach.
Hazards & Notes
⚠️ Flows are elevated at 3,800 cfs — wading requires caution. Felt or studded soles and a wading staff are strongly recommended. The river is excellent for drift boats at these levels. Tribal dipnet fishing is active near Sherars Falls — give all fishers plenty of room. USGS data is provisional and subject to revision.
