Upper Delaware, New York
West Branch Delaware Fishing Report: July 8, 2026
The West Branch remains the safest New York trout choice today, with steady cold release water, light wind, and technical dry-fly or wet-fly opportunities despite warm afternoon air.
- Status
- good
- Flow trend
- stable
- Best window
- Morning fog through the cooler afternoon tailwater window, then any calm evening spinner activity
- Best methods
- dry flies, nymphs, wet flies
Quick Summary
The West Branch is still the strongest trout option in this New York report set. USGS showed 561 cfs and 47.3 F at Hale Eddy, with Stilesville steady at 516 cfs and 44.8 F during the morning refresh. Local Delaware system reporting and the official gauges both point anglers toward the cold tailwater rather than nearby freestones in summer-mode water. Fish nymphs and wet flies early, then watch for sulphurs, olives, Cahills, Isonychias, caddis, and a possible evening spinner window if the wind stays quiet.
Conditions Snapshot
| Field | Value |
|---|---|
| Status | Good on the cold tailwater; warm air makes the West Branch a better trout choice than the freestones |
| Flow | 561 cfs at Hale Eddy; 516 cfs at Stilesville |
| Gauge Height | 2.87 feet at Hale Eddy; 8.09 feet at Stilesville |
| Water Temp | 47.3 F at Hale Eddy; 44.8 F at Stilesville during the morning USGS refresh |
| Clarity | Not reported by official gauges; current local Delaware reporting described the West Branch as in good shape after only light evening rain |
| Trend | Stable release flow, nearly unchanged from yesterday morning |
| Best Window | Morning fog through the cooler afternoon tailwater window, then any calm evening spinner activity |
| Best Method | Nymphs and wet flies before bugs show; dry flies and emergers once fish rise with confidence |
| Wadeability | Limited. Use known gravel and soft edges; avoid pushy crossings and deep slots |
Weather
For Hancock and Hale Eddy, the National Weather Service forecast calls for areas of fog early, then sun with a high near 85 F and very light southwest wind. Tonight should be partly cloudy with fog returning and a low near 63 F. No active NWS alerts were posted at the morning check. The warm afternoon air is the main fishing constraint, so stay on cold release water and carry a thermometer if you move away from the West Branch.
River Notes
The Cannonsville release is giving the West Branch a practical July advantage: cold water, steady flow, and enough volume to keep trout comfortable through a warm day. The best daytime plan is to stay in the upper and middle tailwater, work softly, and treat the clear cold water as technical rather than easy. Fish should use shaded banks, soft seams, tailouts, and riffle edges instead of the fastest center current. Nearby freestone water is warmer, so do not trade cold water for easier wading unless you verify temperatures first.
Hatch Activity
Current Delaware system reports continue to emphasize sulphurs, olives, Cahills, Isonychias, tan caddis, and evening spinners on the colder water. Morning and early afternoon may still require subsurface work, but fog, shade, and any soft light can help olives and emergers. Larger Cahill and Isonychia patterns are also useful as searching dries when there is no organized hatch.
| Hatch | Size | Notes |
|---|---|---|
| Sulphur | 16-20 | Main cold-tailwater mayfly; carry duns, emergers, cripples, and soft hackles |
| Blue Winged Olive | 16-24 | Most useful in fog, soft light, and smooth water where fish can key on small bugs |
| Light Cahill | 14-16 | Good visible searching dry during quiet periods and mixed evening activity |
| Isonychia | 10-12 | Fish nymphs and wets along riffle edges; blind-cast dries over faster seams |
| Tan Caddis | 16-20 | Pupa, soft hackles, and low-riding adults can cover non-mayfly feeders |
| Rusty Spinner | 14-20 | Keep ready for last light if the evening stays calm |
| Yellow Sally and Yellow Drake | 8-16 | Carry a few for mixed summer activity, but match what fish are actually eating |
Recommended Flies
| Category | Fly | Size | Notes |
|---|---|---|---|
| Dry | Sulphur Sparkle Dun, Comparadun, or CDC Emerger | 16-20 | Primary tailwater dry when sulphurs bring fish up |
| Dry | BWO Comparadun or CDC Dun | 16-24 | Use in fog, shade, and quiet slicks |
| Dry | Light Cahill or White Wulff | 14-16 | Visible prospecting fly for pale mayflies and broken riffle water |
| Dry | Isonychia Parachute or Comparadun | 10-12 | Good blind-cast choice along riffles and heavier seams |
| Dry | Rusty Spinner | 14-20 | For the evening flat-water window |
| 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 | Useful when trout flash below emergers but will not commit on top |
| Nymph | Tan Caddis Pupa | 16-18 | Good dropper before or between mayfly windows |
Tactics
Start with a light nymph rig, swung soft hackle, or dry-dropper in shaded seams and tailouts. When bugs appear, slow down and watch individual fish before changing flies; a clean first drift and a long leader matter more than covering water quickly. If you blind-cast, use an Isonychia or Cahill dry where riffles flatten and be ready to downsize if trout start eating small olives or sulphurs. Keep the wading conservative at 500-plus cfs, and stop targeting trout anywhere water approaches 68 F.
