Upper Delaware, New York
West Branch Delaware Fishing Report: July 10, 2026
The West Branch remains the best New York trout option, with a steady 500 cfs release, cold Hale Eddy water, and a cloudier day that should keep the cold tailwater in play.
- Status
- good
- Flow trend
- stable
- Best window
- Cold-water daytime hatches near the upper West Branch, then an evening spinner or dry-fly window if storms stay away
- Best methods
- dry flies, nymphs, wet flies
Quick Summary
The West Branch is again the responsible trout choice in this New York report set. USGS showed 557 cfs and 47.3 F at Hale Eddy, with Stilesville at 507 cfs and 45.3 F during the morning check, so the release-influenced river is cold and steady while nearby freestones are already too warm for trout. Fish nymphs or swung wets before bugs show, then look for sulphurs, olives, Cahills, Isonychias, caddis, and possible evening spinner activity on the colder upper river.
Conditions Snapshot
| Field | Value |
|---|---|
| Status | Good on the cold tailwater; avoid warmer lower-system and freestone trout water |
| 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 | 47.3 F at Hale Eddy; 45.3 F at Stilesville during the morning USGS check |
| Clarity | Not reported by official gauges; current local Delaware context indicates normal summer clarity on the West Branch, with algae possible near Deposit |
| Trend | Stable, with both West Branch gauges essentially unchanged from yesterday morning |
| Best Window | Cold-water daytime hatches near the upper West Branch, then an evening spinner or dry-fly window if storms stay away |
| Best Method | Nymphs and wet flies early; dries, emergers, and spinners when trout feed on top |
| Wadeability | Limited. Fish known crossings and softer edge water; do not push through deep slots at 500-plus cfs |
Weather
For Hancock and Hale Eddy, the National Weather Service forecast calls for a high near 80 F, mostly cloudy skies, and northwest wind around 5 mph. Showers and thunderstorms are possible after 2 PM, with a lower chance lingering into the evening. There were no active NWS alerts at the morning check, but lightning is still a stop-fishing condition. Step off the river if thunder develops, and keep a rain shell in the boat or vest.
River Notes
The Cannonsville release was reported at 500 cfs, and the USGS Stilesville and Hale Eddy readings confirm a steady cold-water setup. That gives anglers a real trout option on a warm July day, especially close enough to the release to keep temperatures safe. The tradeoff is typical summer West Branch selectivity: algae can foul flies near Deposit, the best fish may feed in short windows, and long leaders matter in slower slicks. If you leave the tailwater, use a thermometer before casting; Beaverkill readings were already at or above the trout-stress line this morning.
Hatch Activity
The useful Delaware summer mix has not changed much: sulphurs on the colder West Branch, small olives in shade or clouds, Cahills and Isonychias for larger searching profiles, tan caddis, and spinners if the evening is calm enough. Cloud cover and light north wind should help the daytime dry-fly chance, but the afternoon thunder risk could shorten the window.
| 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 clouds, shade, fog, or smooth slicks with steady risers |
| Light Cahill | 14-16 | Visible searching dry and a good evening profile on broken water |
| Isonychia | 10-12 | Fish nymphs and wets along riffle edges; a dry can prospect when no steady hatch is visible |
| Tan Caddis | 16-20 | Pupa, soft hackles, and low-riding adults can pick up fish between mayfly pushes |
| Rusty Spinner | 14-20 | Keep ready for calm last light if storms do not interrupt the evening |
| Ants and Beetles | 14-20 | Useful summer backups along shaded banks and soft edges |
Recommended Flies
| Category | Fly | Size | Notes |
|---|---|---|---|
| Dry | Sulphur Sparkle Dun, Comparadun, or CDC Emerger | 16-20 | First choice when upper-river sulphurs bring fish up |
| Dry | BWO Comparadun or CDC Dun | 16-24 | Use in shade, clouds, and quiet slicks |
| Dry | Light Cahill or White Wulff | 14-16 | Visible dry for pale mayflies and broken water |
| Dry | Isonychia Parachute or Comparadun | 10-12 | 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 hatch activity is uneven |
| 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 let the fly finish with a controlled swing |
| Wet | Soft Hackle Pheasant Tail or Soft Hackle Sulphur | 14-18 | Good when trout flash under emergers but will not take a dry |
| Nymph | Tan Caddis Pupa | 16-18 | Useful dropper before or between mayfly windows |
Tactics
Start with a light nymph rig or soft hackle in shaded seams, riffle edges, and the softer sides of tailouts. If algae is fouling the fly near the upper river, check the point and dropper every few casts or slide slightly lower where the nymphing and wet-fly water is cleaner. When fish rise, simplify to one dry or a dry with a short emerger dropper, lengthen the leader, and make the first cast count. Keep wading conservative and stop targeting trout anywhere your thermometer approaches 68 F.
