Upper Delaware, New York
West Branch Delaware Fishing Report: July 9, 2026
The West Branch remains the best New York trout option today, with a steady 500 cfs Cannonsville release, cold Hale Eddy water, and summer hatches on the colder tailwater.
- Status
- good
- Flow trend
- stable
- Best window
- Early nymphs and wets, then colder-water dry-fly windows from midday into evening
- Best methods
- dry flies, nymphs, wet flies
Quick Summary
The West Branch is the clear trout choice in this New York set today. USGS showed 557 cfs and 47.1 F at Hale Eddy, with Stilesville at 507 cfs and 45.3 F during the morning check, so the cold tailwater is in good summer shape while nearby freestones are warming. Expect nymphs or swung wets to be most dependable early, then watch the colder water for sulphurs, olives, Cahills, Isonychias, caddis, and a possible spinner window if evening wind and storms stay away.
Conditions Snapshot
| Field | Value |
|---|---|
| Status | Good on the cold tailwater; stay on release-influenced water as the afternoon turns warm |
| Flow | 557 cfs at Hale Eddy; 507 cfs at Stilesville |
| Gauge Height | 2.86 feet at Hale Eddy; 8.08 feet at Stilesville |
| Water Temp | 47.1 F at Hale Eddy; 45.3 F at Stilesville during the morning USGS check |
| Clarity | Not reported by official gauges; current local Delaware reporting has the West Branch in normal summer shape |
| Trend | Stable, with both main West Branch gauges nearly unchanged from yesterday morning |
| Best Window | Early nymphs and wets, then colder-water dry-fly windows from midday into evening |
| Best Method | Nymphs and wet flies before bugs show; dries, emergers, and spinners when fish work the surface |
| Wadeability | Limited. The flow is manageable in known spots, but avoid aggressive crossings and deep pushy slots |
Weather
For Hancock and Hale Eddy, the National Weather Service forecast calls for a high near 88 F with partly sunny skies and very light southwest wind. There is only a small early-day precipitation signal in the hourly forecast, but Friday has a better chance of showers and thunderstorms. Today’s warm air makes water choice more important than fly choice: fish the cold release water and use a thermometer before moving onto warmer tributaries or mainstem reaches.
River Notes
The Cannonsville release was reported at 500 cfs, and the USGS readings at Stilesville and Hale Eddy confirm a steady cold-water setup. That does not make the river easy, but it does make it a responsible trout option on a hot July day. Start in shaded seams, riffle edges, and tailouts where trout can feed without sitting in the fastest current. If you leave the West Branch, verify temperatures before fishing; the Beaverkill and lower system are already close to or above trout-stress levels.
Hatch Activity
Current Delaware system context remains a summer mix: sulphurs on the colder West Branch, small olives in soft light, Cahills and Isonychias for larger searching profiles, tan caddis, and evening spinners. Blind-casting an Isonychia or Cahill can cover water when there is no organized hatch, but be ready to downsize quickly if trout start sipping smaller sulphurs or olives in slick water.
| Hatch | Size | Notes |
|---|---|---|
| Sulphur | 16-20 | Primary cold-tailwater mayfly; carry duns, emergers, cripples, and soft hackles |
| Blue Winged Olive | 16-24 | Most useful in fog, clouds, shade, or smooth water with steady feeders |
| Light Cahill | 14-16 | Good visible searching dry and part of the mixed evening menu |
| Isonychia | 10-12 | Fish nymphs and wets along riffle edges; use the dry as a searching pattern |
| Tan Caddis | 16-20 | Pupa, soft hackles, and low-riding adults can pick off fish between mayfly pushes |
| Rusty Spinner | 14-20 | Keep ready for calm last light |
| Ants and Beetles | 14-20 | Useful summer backups along banks and shaded edges when hatch activity is sparse |
Recommended Flies
| Category | Fly | Size | Notes |
|---|---|---|---|
| Dry | Sulphur Sparkle Dun, Comparadun, or CDC Emerger | 16-20 | Primary cold-tailwater dry when sulphurs bring fish up |
| Dry | BWO Comparadun or CDC Dun | 16-24 | Use in fog, shade, and quiet slicks |
| Dry | Light Cahill or White Wulff | 14-16 | Visible option for pale mayflies and broken water |
| Dry | Isonychia Parachute or Comparadun | 10-12 | Good prospecting fly along riffles and heavier seams |
| Dry | Rusty Spinner | 14-20 | For the evening flat-water window |
| Dry | Ant or Beetle | 14-20 | Bank-side summer backup when fish are opportunistic |
| Nymph | Pheasant Tail, Frenchie, or Split-Back Mayfly | 14-18 | Light nymphing through soft seams before surface activity develops |
| Nymph | Isonychia Nymph | 10-12 | Work riffle edges and finish the drift with a controlled swing |
| Wet | Soft Hackle Pheasant Tail or Soft Hackle Sulphur | 14-18 | Useful when trout flash below emergers but will not commit on top |
| Nymph | Tan Caddis Pupa | 16-18 | Good dropper before or between mayfly windows |
Tactics
Begin with a light nymph rig or a swung soft hackle through shaded seams, riffle edges, and the softer sides of tailouts. Once fish start showing, switch to a single dry or dry-and-emerger setup, lengthen the leader, and work one fish at a time rather than running the bank. Use a Cahill or Isonychia dry as a searching fly in broken water, but downsize to sulphurs or olives in slow slicks. Keep wading conservative at 500-plus cfs, and stop targeting trout anywhere water approaches 68 F.
