Upper Delaware, New York
West Branch Delaware River Fishing Report: June 29, 2026
The West Branch is the best New York trout option again, with cold release water, steady flows, and a summer dry-fly program that should fish best outside the bright midday heat.
- Status
- good
- Flow trend
- stable
- Best window
- Early before the sun gets high, then the evening hatch and spinner window
- Best methods
- dry flies, dry-dropper, wet flies, nymphs
Quick Summary
The West Branch remains the strongest trout option in the active New York report set. USGS showed 571 cfs and 46.9 F at Hale Eddy, with Stilesville steady at 507 cfs and 44.4 F during the morning check. The day is forecast to be hot and sunny near Hancock, so use the cold tailwater advantage but avoid treating the whole river system as an all-day trout option. Local Upper Delaware context continues to point to sulphurs, Light Cahills, Isonychias, olives, caddis, and late spinners; fish subsurface or dry-dropper rigs until trout show themselves, then switch to precise dries in the evening.
Conditions Snapshot
| Field | Value |
|---|---|
| Status | Good; cold release water and stable flows give anglers a useful trout plan, but the hot sunny afternoon favors shaded water and evening timing |
| Flow | 571 cfs at Hale Eddy; 507 cfs at Stilesville |
| Gauge Height | 2.90 feet at Hale Eddy; 8.06 feet at Stilesville |
| Water Temp | 46.9 F at Hale Eddy; 44.4 F at Stilesville |
| Clarity | Not reported by official gauges; current local context does not point to a major West Branch color problem |
| Trend | Stable release water, with Hale Eddy slightly lower than yesterday morning |
| Best Window | Early before the sun gets high, then the evening hatch and spinner window |
| Best Method | Nymphs, wets, and dry-dropper rigs before steady rises; sulphur, olive, Cahill, Isonychia, caddis, and spinner dries for feeding fish |
| Wadeability | Limited but workable from familiar edges and softer access points; a boat remains the easier way to cover the river |
Weather
For Hancock, NY, the National Weather Service forecast calls for sunny skies and a high near 88 F. Wind should be very light from the northeast around 1 mph. Tonight is expected to be partly cloudy with a low near 63 F. No active NWS alerts were returned for the Hancock point during the morning check, but the hot, bright forecast makes timing and cold-water selection important.
River Notes
The upper West Branch is carrying enough cold release water to stay in play while the freestones warm. Stilesville is holding near the 500 cfs release level, and Hale Eddy is just under 600 cfs, which is friendly for boats and selective for wading. Start in known access points, fish from stable edge positions, and skip any pushy crossing. Bright sun can flatten the midday dry-fly bite, so use nymphs, wets, or a dry-dropper through seams, riffle edges, and shaded banks until fish show a consistent surface rhythm.
Hatch Activity
Current Upper Delaware context continues to center on sulphurs, Light Cahills, Isonychias, Blue Winged Olives, caddis, and evening spinners. Expect some trout to feed just under the film before clean rises develop, especially when the sun is high.
| Hatch | Size | Notes |
|---|---|---|
| Sulphur | 16-18 | Main summer mayfly to plan around; carry emergers, duns, cripples, and spinners |
| Blue Winged Olive | 16-22 | Better if clouds build; use low-profile dries or emergers for careful risers |
| Isonychia / Slate Drake | 10-12 | Nymphs, wets, and larger dries fit riffles, fast seams, and broken bank water |
| Light Cahill | 14-16 | Useful larger pale mayfly option in riffles and late-day glides |
| Tan Caddis | 16-18 | Fish pupa and soft hackles before adults become obvious |
| Rusty Spinner | 10-20 | Important in the evening if wind stays down |
Recommended Flies
| Category | Fly | Size | Notes |
|---|---|---|---|
| Dry | Sulphur Usual, Sparkle Dun, or Comparadun | 16-18 | First dry choice when pale duns show and fish feed cleanly |
| Dry | Sulphur Emerger or Cripple | 16-18 | Use when rises are subtle or fish are taking in the film |
| Dry | BWO Comparadun or CDC Dun | 18-22 | Good if clouds or small olives create slower, deliberate rises |
| Dry | Light Cahill Parachute or Grey Fox-style searching dry | 12-16 | Good over riffles and as the dry in a dry-dropper setup |
| Dry | Rusty Spinner | 10-20 | Carry a range for the last-light spinner fall |
| Nymph | Isonychia Nymph | 10-12 | Let it lift or swing at the end of the drift near riffle edges |
| Nymph | Pheasant Tail, Barr Emerger, or Split Back-style mayfly nymph | 14-18 | Good dropper below a sulphur dry or searching dry |
| Wet | Soft Hackle or Flymph | 12-16 | Swing through riffle tails when bugs are active but rises are scattered |
| Other | Caddis Pupa | 16-18 | Useful below the surface when tan caddis are active |
Tactics
Fish the coldest tailwater water first and stay flexible. A dry-dropper with a larger Cahill, Grey Fox, or Slate Drake-style dry over a small mayfly nymph can cover riffles before a defined hatch starts. If fish begin rising, lengthen the leader, remove extra weight and indicators, and make fewer casts from a better angle. Save spinner patterns for evening and do not extend trout fishing into warmer lower river sections just because the West Branch gauges are cold.
