Upper Delaware, New York
West Branch Delaware Fishing Report: July 14, 2026
The West Branch has a strong cold-water release cushion this morning, with Hale Eddy near 930 cfs and 46.0 F, but the active Heat Advisory makes early, late, and cold-water discipline important.
- Status
- good
- Flow trend
- rising
- Best window
- Early and late around the cold upper West Branch; midday only where the release water stays cold
- Best methods
- dry flies, nymphs, wet flies
Quick Summary
The West Branch remains the best trout option in this New York set because the release water is cold and useful. USGS showed 930 cfs and 46.0 F at Hale Eddy, with Stilesville at 570 cfs and 45.9 F during the 9 AM refresh, so the upper river has both temperature protection and enough push to make wading selective. The tradeoff is heat: the National Weather Service has a Heat Advisory in effect through this evening and forecasts a high near 94 F with haze and west wind, so plan around cold water, shade, and lower-light windows instead of treating the whole system as equal.
Conditions Snapshot
| Field | Value |
|---|---|
| Status | Good on the cold West Branch tailwater; avoid warmer freestone and lower-system trout water during the heat |
| Flow | 930 cfs at Hale Eddy; 570 cfs at Stilesville |
| Gauge Height | 3.54 feet at Hale Eddy; 8.16 feet at Stilesville |
| Water Temp | 46.0 F at Hale Eddy; 45.9 F at Stilesville during the 9 AM USGS refresh |
| Clarity | Not reported by official gauges; current local Delaware context continues to emphasize the cold upper West Branch |
| Trend | Rising versus yesterday morning after another Cannonsville pulse; still a fishable cold release range |
| Best Window | Early and late around the cold upper West Branch; midday only where the release water stays cold |
| Best Method | Dry flies when fish show on sulphurs, olives, Cahills, or spinners; nymphs and wet flies between surface windows |
| Wadeability | Limited. Hale Eddy near 936 cfs is not casual wading; use edges, established crossings, or a boat |
Weather
For Hancock and Hale Eddy, the National Weather Service has a Heat Advisory in effect through 8 PM. The forecast calls for sunshine and haze with a high near 94 F, heat index values near 97 F, and west wind from 3 to 10 mph. Tonight is forecast mostly clear with a low around 72 F. The air will be hot enough that the tailwater release is the main trout-safety factor, so stay close to the cold influence and be careful about long handling times even when the gauge temperature looks excellent.
River Notes
Cannonsville release pulses are again shaping the day. Hale Eddy remains several hundred cfs higher than yesterday morning, Stilesville is still above the 500-cfs base range after easing from the early pulse, and both official temperatures are in the mid-40s. That is good trout water, but it also means anglers should pick wading spots carefully and avoid trying to cross broad slicks or pushy tailouts. The best plan is to work the upper West Branch where the cold release dominates, then reassess light, wind, and surface activity before committing to lower water.
Hatch Activity
Current local Delaware context supports the same July cold-tailwater mix: sulphurs on the upper West Branch, small olives mixed in, Isonychias, summer Cahills, tan caddis, and evening spinners when the light gets low. Terrestrials are still worth carrying along grassy banks, but the best dry-fly fishing should come from matching actual bugs over cold water rather than blind prospecting through the heat of the day.
| Hatch | Size | Notes |
|---|---|---|
| Sulphur | 16-20 | Primary upper West Branch summer mayfly; carry duns, emergers, cripples, and soft hackles |
| Blue Winged Olive | 18-24 | Small olives can mix with sulphurs, especially in shade, haze, or soft slicks |
| Light Cahill | 14-16 | Useful visible searching dry and evening profile on broken water |
| Isonychia | 10-12 | Nymphs and wets are good through riffle edges; dries can cover sparse larger rises |
| Tan Caddis | 16-20 | Pupa and soft hackles can fill gaps before and after mayfly activity |
| Rusty Spinner | 14-20 | Carry for last light if the wind and heat ease enough for a fall |
| Ants and Beetles | 14-20 | Bank-side backups for shaded edges and summer flats |
Recommended Flies
| Category | Fly | Size | Notes |
|---|---|---|---|
| Dry | Sulphur Sparkle Dun, Comparadun, or CDC Emerger | 16-20 | First choice for upper-river sulphur fish |
| Dry | BWO Comparadun or CDC Dun | 18-24 | Use for small olive fish in slicks and shaded lanes |
| Dry | Light Cahill or White Wulff | 14-16 | Visible dry for pale mayflies and broken-water prospecting |
| Dry | Isonychia Parachute or Comparadun | 10-12 | Good larger profile along riffles and heavier seams |
| Dry | Rusty Spinner | 14-20 | Keep ready for calm last light |
| Dry | Ant or Beetle | 14-20 | Summer bank option when hatch activity is uneven |
| Nymph | Pheasant Tail, Frenchie, or Split-Back Mayfly | 14-18 | Fish soft seams before the surface window develops |
| Nymph | Isonychia Nymph | 10-12 | Work riffle edges and let the fly finish with a controlled swing |
| Wet | Soft Hackle Sulphur or Soft Hackle Pheasant Tail | 14-18 | Good during emerging bugs or when fish flash below dries |
| Nymph | Tan Caddis Pupa | 16-18 | Useful dropper between mayfly pushes |
Tactics
Start with the coldest water and be conservative about footing. With Hale Eddy near 936 cfs, edge seams, inside bends, and soft bank water are better choices than mid-river wading. If fish are not showing, use a compact nymph rig or swing soft hackles through riffle edges, then switch to a longer leader and single dry or dry-emerger setup when sulphurs, olives, or Cahills get fish looking up. The safety note today is heat: the gauge temperature is excellent on the West Branch, but lower and warmer water can be stressful, so carry a thermometer if you leave the cold release influence.
