Upper Delaware, New York
West Branch Delaware Fishing Report: July 4, 2026
The West Branch remains cold and fishable for the holiday, but falling release water and an afternoon thunderstorm forecast put the best trout windows early, shaded, and late.
- Status
- good
- Flow trend
- falling
- Best window

- Best methods
- dry flies, nymphs, wet flies
Quick Summary
The West Branch is the best New York trout option in this report set today. USGS showed 754 cfs and 47.1 F at Hale Eddy, with Stilesville at 560 cfs and 45.5 F during the morning check, so the tailwater remains cold while nearby freestones are already too warm for trout. The release pulse has stepped down again, which means softer edges are fishable but mid-channel wading should stay conservative. Fish the morning shade, watch the sulphur and olive water in the evening, and treat afternoon thunderstorms as the main safety issue.
Conditions Snapshot
| Field | Value |
|---|---|
| Status | Good on the cold tailwater, with falling release water, limited wading, and afternoon thunderstorm risk |
| Flow | 754 cfs at Hale Eddy; 560 cfs at Stilesville |
| Gauge Height | 3.24 feet at Hale Eddy; 8.14 feet at Stilesville |
| Water Temp | 47.1 F at Hale Eddy; 45.5 F at Stilesville during the morning USGS check |
| Clarity | Not reported by official gauges; recent local context points to cold tailwater water as the reliable choice |
| Trend | Falling after another overnight release pulse, with cold water still providing good trout-temperature protection |
| Best Window | Morning shade and fog, then the evening spinner and emerger window if storms stay away |
| Best Method | Nymphs and wet flies before steady surface activity; technical dries, emergers, and spinners during sulphur, olive, Cahill, Isonychia, or caddis windows |
| Wadeability | Limited. Stay on known edges and do not push into heavier current while the release is changing |
Weather
For Hancock and Hale Eddy, the National Weather Service forecast calls for a high near 87 F, partly sunny conditions early, light northwest wind, and showers and thunderstorms becoming likely from midday into the afternoon. Rainfall could be light during the day with additional storms tonight. The cooler air helps compared with the recent heat, but lightning and sudden local runoff still matter. Have a short exit plan before fishing long flats or exposed banks.
River Notes
The current plan is to stay on the cold West Branch rather than moving to warmer parts of the system. The river is lower than yesterday morning but still carrying enough release water for boats and careful edge wading. Falling water can make fish slide from banks and shelves toward defined seams, and it can also make flat-water risers more selective. Start where the cold release gives you cover and temperature stability, then adjust as the flow settles. Nearby Beaverkill, lower East Branch, and mainstem water should be checked carefully or avoided for trout where temperatures are over the line.
Hatch Activity
Upper Delaware reports and early-July seasonal context continue to point to sulphurs, Light Cahills, Isonychias, Blue Winged Olives, caddis, dark sedges, and spinners. The cold West Branch is the right place to use that information today. Expect the better dry-fly work to come in shade, cloud cover, fog, or the evening window rather than under high sun.
| Hatch | Size | Notes |
|---|---|---|
| Sulphur | 16-20 | Main summer mayfly; carry duns, emergers, cripples, soft hackles, and small droppers |
| Blue Winged Olive | 18-24 | Best during fog, clouds, light rain, or storm-softened light |
| Isonychia | 10-12 | Nymphs and swung wets can cover riffle edges and bank-side current |
| Light Cahill | 14-16 | Useful larger pale mayfly when evening rises are scattered |
| Tan Caddis | 16-20 | Pupa, soft hackles, and low-riding adults can fill gaps before steady mayfly activity |
| Dark Blue Sedge | 14 | Darker caddis or skated patterns can matter in faster evening water |
| Rusty Spinner | 14-20 | Keep ready for last light if thunderstorm wind does not break up the fall |
Recommended Flies
| Category | Fly | Size | Notes |
|---|---|---|---|
| Dry | Sulphur Comparadun, Usual, or Sparkle Dun | 16-20 | Primary dry when fish settle into pale mayflies |
| Dry | BWO Comparadun or CDC Dun | 18-24 | Use in fog, clouds, light rain, or low light |
| Dry | Light Cahill or White Wulff | 14-16 | Visible searching dry for mixed evening bugs |
| Dry | Rusty Spinner | 14-20 | For the final flat-water window when fish are sipping cleanly |
| Nymph | Pheasant Tail, Frenchie, or Split-Back Mayfly | 14-18 | Good under a dry or lightly weighted through softer seams |
| Nymph | Isonychia Nymph | 10-12 | Fish riffle edges and let the fly finish on a controlled swing |
| Wet | Soft Hackle Pheasant Tail or Soft Hackle Sulphur | 14-18 | Good when fish flash below emergers but do not show noses |
| Nymph | Tan Caddis Pupa | 16-18 | Useful before the evening surface window |
| Other | Ant or Beetle | 14-18 | Worth carrying for shaded banks if hatch activity stalls |
Tactics
Start with nymphs, wet flies, or a dry-dropper along shaded seams, soft banks, and current breaks while the river settles from the overnight pulse. If fish begin rising in a repeatable lane, switch to a single dry or dry-and-emerger setup and lengthen the leader before changing flies too often. Keep your feet conservative; falling water can make wading feel easier just as fish move into softer, quieter holding water. If thunderheads build, leave exposed water early. Do not use the cold West Branch as a reason to fish warm neighboring trout water later in the day.
