Upper Delaware, New York
West Branch Delaware Fishing Report: June 30, 2026
The West Branch remains the safest Upper Delaware trout option in the heat, with cold morning water, a stronger release-influenced flow, and the best dry-fly window early or very late.
- Status
- good
- Flow trend
- rising
- Best window
- Early morning fog and the last two hours of light
- Best methods
- dry flies, nymphs, wet flies
Quick Summary
The West Branch is the best New York trout target in this morning's report set. USGS showed 716 cfs and 46.2 F at Hale Eddy during the 8 AM check, with Stilesville at 560 cfs and 44.6 F, so the tailwater has the cold-water buffer the freestones do not. The day is still hot, humid, and storm-prone, so fish the fog or shade early, rest during the brightest heat, and come back for sulphurs, olives, Cahills, Isonychias, caddis, and possible spinner activity toward dark.
Conditions Snapshot
| Field | Value |
|---|---|
| Status | Good on the cold tailwater; watch heat, storms, and boat traffic through the afternoon |
| Flow | 716 cfs at Hale Eddy; 560 cfs at Stilesville |
| Gauge Height | 3.24 feet at Hale Eddy; 8.08 feet at Stilesville |
| Water Temp | 46.2 F at Hale Eddy; 44.6 F at Stilesville during the morning USGS check |
| Clarity | Not reported by official gauges; recent local reports described the West Branch as a clearer, safer cold-water option than the warm freestones |
| Trend | Higher than yesterday's local morning reports after rain and release-influenced flow; still fishable |
| Best Window | Early morning fog and shade, then the last two hours of light if storms stay away |
| Best Method | Nymphs and wet flies before surface activity; technical dries and emergers when fish show |
| Wadeability | Limited. Pick soft edges and known access; floating remains the cleaner way to cover water at this level |
Weather
For the Hancock and Hale Eddy area, the National Weather Service forecast calls for a mostly cloudy morning turning into a slight chance of showers and thunderstorms this afternoon, with a high near 90 F and heat index values around the mid-90s. Southwest wind is forecast at 2 to 8 mph. Tonight stays warm near 67 F with another small thunderstorm chance before mostly cloudy conditions. Lightning and heat are the safety issues even though the tailwater itself is cold.
River Notes
Cold water is the reason to choose the West Branch today. The Hale Eddy gauge was in the mid-40s during the morning check, while nearby freestones are low and warming fast. The bump to 716 cfs gives fish more cover and should keep some softer edges in play, but it also makes random wading a poor plan. Start with slower seams, shaded banks, and inside bends. If fog holds or clouds thicken, look sooner for olives and sulphurs. If the sun breaks hard, expect the better dry-fly work to slide toward evening.
Hatch Activity
Regional Upper Delaware sources checked this morning and from the most recent local posts continue to point to a summer mix rather than one simple hatch. Sulphurs, Blue Winged Olives, Light Cahills, Isonychias, tan caddis, and late spinners are all worth having. Presentation matters more than changing patterns every cast: long leaders, accurate reach casts, and a quiet first drift are important in the clear tailwater.
| Hatch | Size | Notes |
|---|---|---|
| Sulphur | 16-18 | Primary summer dry-fly target; carry duns, emergers, cripples, and soft hackle droppers |
| Blue Winged Olive | 18-22 | Best if clouds, fog, or showers keep the light down |
| Isonychia | 10-12 | Fish nymphs through riffle water and swing the end of the drift toward the bank |
| Light Cahill | 14-16 | Good larger pale mayfly to cover scattered evening rises |
| Tan Caddis | 16-20 | Pupa and soft hackles can fill the gap before fish commit to dries |
| Rusty Spinner | 14-20 | Keep ready for the last-light window if wind and storms stay manageable |
Recommended Flies
| Category | Fly | Size | Notes |
|---|---|---|---|
| Dry | Sulphur Usual, Comparadun, or Sparkle Dun | 16-18 | Match the main summer hatch on flat tailwater glides |
| Dry | BWO Comparadun or CDC Dun | 18-22 | Use under clouds, fog, or light rain when smaller olives show |
| Dry | Light Cahill or White Wulff | 14-16 | Useful searching dry and visible evening pattern |
| Dry | Rusty Spinner | 14-20 | Last-light fly if fish switch to spent mayflies |
| Nymph | Pheasant Tail, Frenchie, or Split-Back Mayfly | 14-18 | Drop under a sulphur dry or fish lightly weighted before surface activity |
| Nymph | Isonychia Nymph | 10-12 | Work riffles and bank-side swing finishes |
| Wet | Soft Hackle Pheasant Tail | 14-18 | Good emerger impression when fish flash below the surface |
| Nymph | Tan Caddis Pupa | 16-18 | Fish through riffle seams before the evening dry window |
Tactics
Fish this like summer tailwater, not spring freestone water. Use nymphs, wet flies, or a dry-dropper in shaded seams until you find steady risers. Once fish show, shorten the fly changes and lengthen the leader: a clean first cast with the right drift will beat a perfect hatch guess with drag. Avoid midday trout fishing on warmer nearby waters, keep an eye on radar, and leave the river immediately if thunder builds.
