Quick Summary
The West Branch remains the most dependable trout water in the active New York report set. USGS showed 596 cfs and 47.3 F at Hale Eddy, with Stilesville steady at 507 cfs and 44.6 F during the 8 AM check. Current Upper Delaware source context points to cloudy, humid conditions, cold release water, and a summer hatch mix of sulphurs, Cahills, Isonychias, olives, and caddis. Start subsurface or with a dry-dropper while the river is quiet, then be ready to simplify to dries when fish settle into a hatch or evening spinner fall.
Conditions Snapshot
| Field | Value |
|---|---|
| Status | Good; cold tailwater temperatures, steady release flows, and light wind give anglers a clear trout option |
| Flow | 596 cfs at Hale Eddy; 507 cfs at Stilesville |
| Gauge Height | 2.94 feet at Hale Eddy; 8.08 feet at Stilesville |
| Water Temp | 47.3 F at Hale Eddy; 44.6 F at Stilesville |
| Clarity | Not reported by official gauges; current local context does not point to a major color problem on the West Branch |
| Trend | Stable release water at Stilesville and a slightly lower Hale Eddy reading than yesterday morning |
| Best Window | Midday cloud cover into the evening spinner window if storms stay away |
| 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 at familiar access points and soft edge water; a boat remains the easier way to cover the river |
Weather
For Hancock, NY, the National Weather Service forecast calls for partly sunny skies and a high near 79 F with very light west wind. The hourly forecast starts mostly cloudy around 8 AM, then trends partly sunny through midday. Tonight brings a low near 56 F, patchy fog, and isolated showers or thunderstorms early, so leave the water if thunder develops. No active NWS alerts were returned for the Hancock point during the morning check.
River Notes
The upper West Branch has the cold-water advantage again today. Stilesville is holding at the 500 cfs release level, while Hale Eddy is just under 600 cfs, which is enough water for good drift-boat coverage and enough push to make wading selective. Focus on seams, riffle edges, shaded banks, and flats where fish show themselves rather than pushing deep to reach one riser. The light wind helps dry-fly fishing, and the mix of clouds and cool release water should keep midday sulphurs and olives in play before the evening spinner window.
Hatch Activity
Current Upper Delaware context continues to center on sulphurs, Isonychias, Blue Winged Olives, tan caddis, Light Cahills, and spinner activity. Keep emergers and cripples close; fish may take just under the film before committing to duns or spinners.
| Hatch | Size | Notes |
|---|---|---|
| Sulphur | 16-18 | Primary summer hatch to plan around; carry emergers, duns, cripples, and spinners |
| Blue Winged Olive | 16-22 | Clouds favor olives; use low-profile dries or emergers for selective fish |
| Isonychia / Slate Drake | 10-12 | Nymphs, wets, and larger dries fit riffles and broken seams |
| Tan Caddis | 16-20 | Fish pupa and soft hackles before adults become obvious |
| Light Cahill | 14-16 | Good larger pale mayfly option in riffles and late-day glides |
| Rusty Spinner | 10-20 | Important in the evening if wind stays down and thunderstorms hold off |
Recommended Flies
| Category | Fly | Size | Notes |
|---|---|---|---|
| Dry | Sulphur 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 under clouds and for small, deliberate rises |
| Dry | Light Cahill Parachute | 14-16 | Covers larger pale mayflies in broken water and evening slicks |
| 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 or Frenchie | 14-18 | Compact mayfly dropper before the main hatch |
| 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
Start with an Isonychia nymph, small mayfly nymph, caddis pupa, soft hackle, or dry-dropper through seams and riffle edges. If fish begin rising consistently, lengthen the leader, drop to a single dry or dry-and-emerger pair, and avoid lining fish in the clear tailwater. Keep a spinner box ready for evening, but do not wait out lightning in the valley. At this flow, wade from known edges and avoid pushy mid-river slots.
