West Branch Delaware Fishing Report: July 11, 2026
The West Branch is the clear New York trout option today, with cold release water, a modest bump at Hale Eddy, and a summer mix of sulphurs, olives, Cahills, Isonychias, and caddis.
- Status
- good
- Flow trend
- rising
- Best window
- Cold-water daytime dry-fly windows on the upper West Branch, then evening if storms miss the river
- Best methods
- dry flies, nymphs, wet flies
Quick Summary
The West Branch remains the best trout choice in this New York report set. USGS showed 653 cfs and 46.8 F at Hale Eddy, with Stilesville at 525 cfs and 45.3 F during the morning check, so the river has cold release water while nearby freestones are near or above the trout-stress line. The release was reported at 500 cfs, with a small overnight pulse showing in the Hale Eddy number; fish the coldest water first, use nymphs or swung wets when nothing is rising, and be ready for sulphurs, olives, Cahills, Isonychias, caddis, and evening spinners if thunderstorms stay away.
Conditions Snapshot
| Field | Value |
|---|---|
| Status | Good on the cold tailwater; avoid warmer freestone trout water nearby |
| Flow | 653 cfs at Hale Eddy; 525 cfs at Stilesville |
| Gauge Height | 2.98 feet at Hale Eddy; 8.09 feet at Stilesville |
| Water Temp | 46.8 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 fishable summer clarity, with algae still possible near Deposit |
| Trend | Rising modestly at Hale Eddy from yesterday morning; nearly steady at Stilesville |
| Best Window | Cold-water daytime dry-fly windows on the upper West Branch, then evening if storms miss the river |
| Best Method | Nymphs and wet flies between hatches; dries, emergers, and spinners when trout feed on top |
| Wadeability | Limited. Use known crossings and softer edges; do not push deep seams at 600-plus cfs |
Weather
For Hancock and Hale Eddy, the National Weather Service forecast calls for a high near 83 F, partly sunny skies, and light northeast wind. A chance of showers and thunderstorms develops during the day, with a smaller storm chance before evening. There were no active NWS alerts at the morning check, but lightning is still a hard stop. Pack a rain shell, watch the sky, and leave exposed water when thunder is nearby.
River Notes
The West Branch has the cold water advantage today. Hale Eddy is up about 100 cfs from yesterday morning while Stilesville is only slightly higher, which fits a small overnight release pulse settling back toward normal. That little extra water helps the tailwater fish bigger than the low summer freestones, but it also keeps wading selective. Stay near the upper cold-water influence if you want daytime dries, check flies often if algae is fouling them around Deposit, and slide lower only when nymphing or swinging wets makes more sense than watching blank slicks.
Hatch Activity
The current Delaware summer menu is still in play: sulphurs on the colder West Branch, olives in shade or clouds, Cahills and Isonychias as larger searching profiles, tan caddis, terrestrials along banks, and spinners at last light if the air stays calm enough. Afternoon thunderstorms can improve cloud cover, but do not trade safety for a hatch.
| 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 slow slicks with steady risers |
| Light Cahill | 14-16 | Good visible searching dry and a reasonable evening profile on broken water |
| Isonychia | 10-12 | Nymphs and wets belong along riffle edges; a dry can prospect when risers are sparse |
| 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 cut off the evening |
| Ants and Beetles | 14-20 | Useful summer backups along shaded banks and soft edge water |
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
Begin with a light nymph rig or a soft hackle in shaded seams, riffle edges, and the softer sides of tailouts. If algae is coating the fly near Deposit, check the point and dropper often or move to cleaner nymphing water. When fish start rising, simplify to one dry or a dry with a short emerger dropper, lengthen the leader, and get above the fish before casting. Keep wading conservative at the higher Hale Eddy flow, and stop targeting trout anywhere your thermometer approaches 68 F.
