Upper Delaware, New York
West Branch Delaware Fishing Report: July 6, 2026
The West Branch remains the safest cold-water trout option, with steady release flows, cold temperatures, good reported clarity, and a Flood Watch through Tuesday morning.
- Status
- good
- Flow trend
- stable
- Best window
- Morning through early afternoon between storms, then only any safe evening clearing
- Best methods
- dry flies, nymphs, wet flies
Quick Summary
The West Branch is still the best New York trout choice in this report set because the Cannonsville release is keeping the tailwater cold while nearby freestones are high, rising, or too warm for a responsible trout recommendation. USGS showed 576 cfs and 48.2 F at Hale Eddy, with Stilesville at 516 cfs and 45.7 F during the 9 AM refresh. Those flows are fishable, and West Branch Angler reported good clarity around 8:30 AM, but the National Weather Service Flood Watch means this remains a limited-wading day. Start with nymphs, wets, or a dry-dropper until fish show, then be ready for sulphurs, olives, Cahills, Isonychias, caddis, and spinners in soft light.
Conditions Snapshot
| Field | Value |
|---|---|
| Status | Good on the cold tailwater, with stable release flows, limited wading, and a National Weather Service Flood Watch through Tuesday morning |
| Flow | 576 cfs at Hale Eddy; 516 cfs at Stilesville |
| Gauge Height | 2.90 feet at Hale Eddy; 8.09 feet at Stilesville |
| Water Temp | 48.2 F at Hale Eddy; 45.7 F at Stilesville during the 9 AM USGS refresh |
| Clarity | Not reported by official gauges; West Branch Angler reported good clarity at Hale Eddy around 8:30 AM, and Delaware River Club reported the West Branch still looked fine after morning rain |
| Trend | Near stable to slightly up from yesterday morning at Hale Eddy, with Stilesville holding around the same release level |
| Best Window | Morning through early afternoon between storms, then only any safe evening clearing or spinner window |
| Best Method | Nymphs, wet flies, and dry-dropper rigs until fish rise; technical dries, emergers, and spinners when surface feeding develops |
| Wadeability | Limited. Use known gravel, soft edges, and short exits; stay out of heavy current and leave exposed water when storms build |
Weather
For Hancock and Hale Eddy, the National Weather Service forecast calls for showers and thunderstorms with a high near 72 F, east wind around 5 mph, and an 80 percent chance of precipitation. New rainfall of a quarter to a half inch is possible today, followed by a chance of showers tonight and more unsettled weather Tuesday. A Flood Watch is in effect through Tuesday morning, so treat tributaries, feeder creeks, islands, and low crossings conservatively even if the main West Branch release remains steady. The lower light and gentle wind can help dry-fly fishing, but lightning and quick runoff are the main constraints. Do not wait on exposed bars or islands if thunder becomes audible.
River Notes
The West Branch has the strongest trout case today because the upper tailwater is cold and the release is steady. Delaware River Club's current report noted a 500 cfs Cannonsville release, a West Branch that still looked fine after rain, and higher flows in the East Branch and Beaverkill drainages. West Branch Angler's 8:30 AM update also reported only a small bump at Hale Eddy, good clarity, mid-day sulphurs on the upper West Branch, olives under the wet overcast forecast, and nymphing as a good backup. That matches the official gauge picture: the West Branch is manageable, while the freestone water has become a safety and temperature problem. Fish the cold tailwater deliberately rather than moving to warmer side water just because it looks easier to wade.
Hatch Activity
Current Upper Delaware local context and early-July seasonality point to sulphurs, Light Cahills, Isonychias, olives, caddis, terrestrials, and evening spinners. West Branch Angler reported small mid-day sulphurs on the upper West Branch and expected the wet overcast pattern to help olives. Expect the best surface work in fog, clouds, rain-softened light, and any safe evening clearing rather than in flat bright light.
| Hatch | Size | Notes |
|---|---|---|
| Sulphur | 16-20 | Main cold-tailwater mayfly; carry duns, emergers, cripples, and soft hackles |
| Blue Winged Olive | 18-24 | Best in fog, clouds, light rain, or storm-softened light |
| Isonychia | 10-12 | Nymphs, wets, and visible dries can cover riffle edges and faster bank lanes |
| Light Cahill | 14-16 | Good searching dry when pale bugs mix into the evening hatch |
| Tan Caddis | 16-20 | Pupa, soft hackles, and low-riding adults can fill gaps before steady mayfly activity |
| Rusty Spinner | 14-20 | Keep ready for last light if rain and wind do not break up the spinner fall |
| Ants, Beetles, and Hoppers | 10-18 | Useful along shaded banks when hatch activity stalls; hoppers become more relevant through the warm season |
Recommended Flies
| Category | Fly | Size | Notes |
|---|---|---|---|
| Dry | Sulphur Comparadun, Usual, or Sparkle Dun | 16-20 | Primary dry when fish key on pale mayflies in the cold water |
| Dry | BWO Comparadun or CDC Dun | 18-24 | Use during fog, clouds, light rain, or low light |
| Dry | Light Cahill or White Wulff | 14-16 | Visible option for scattered evening fish |
| Dry | Rusty Spinner | 14-20 | For flat-water sippers near last light when weather allows |
| Dry | Ant, Beetle, or Small Hopper | 10-18 | Good shaded-bank choice if hatch activity is thin |
| Nymph | Pheasant Tail, Frenchie, or Split-Back Mayfly | 14-18 | Fish lightly weighted through softer seams and tailouts |
| Nymph | Isonychia Nymph | 10-12 | Work 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 without showing steady noses |
| Nymph | Tan Caddis Pupa | 16-18 | Useful before the evening surface window |
Tactics
Start in the coldest release water with soft bank seams, shaded flats, and riffle tailouts. A dry-dropper, light nymph rig, or swung wet fly is the right searching approach until you see repeatable rises. If the water takes on color after heavier cells, a small dark or olive streamer can be worth a careful bank pass, but do not use that as a reason to wade pushy water. Once a fish settles into a lane, simplify to one dry or a dry with an emerger and lengthen the leader before cycling through too many patterns. Keep the day mobile but conservative: rain can move small feeders quickly, the Flood Watch raises cutoff risk, and thunderstorms make exposed wading a poor bet. If you leave the West Branch, carry a thermometer and stop targeting trout before water reaches 68 F.
