- Best methods
- dry flies, nymphs, wet flies
Quick Summary
The West Branch remains the strongest trout option in this New York report set because Hale Eddy is cold, steady, and at a comfortable wading flow. USGS showed 566 cfs, 2.88 feet, and 46.0 F at Hale Eddy at about 7:45 AM EDT, nearly unchanged from yesterday morning. Local Delaware-system context from June 5 still points to steady reservoir releases, early-June sulphurs, caddis, March Browns, Gray Fox, Cahills, olives, Isonychia, Green Drakes, and evening spinners, but no fresh June 6 Delaware River Club page was reachable during this check. The National Weather Service has showers and thunderstorms likely late in the day, so fish the morning and early afternoon carefully, then get off exposed water if thunder develops.

Weather
For Hancock, NY, the National Weather Service forecast calls for a high near 85 F with mostly cloudy skies and a chance of showers and thunderstorms after 2 PM, becoming likely late in the afternoon. Southwest wind should run 1-8 mph. Tonight is forecast to bring showers and thunderstorms early, then patchy fog with a low around 59 F. No active NWS alerts were found for the Hancock point at report time, but lightning is the main safety constraint if storms build over the valley.
River Notes
At 566 cfs, Hale Eddy is still a practical wading flow, not a high-water boat-only situation. Cover bank-side seams before stepping in, then work riffles, shaded shelves, and soft edges where cold release water keeps fish comfortable. The morning temperature gives trout a good buffer, but warm air can make downstream or mainstem water a different decision than the Hale Eddy gauge. If you leave the upper tailwater influence, carry a thermometer and stop targeting trout if water approaches 68 F.
Hatch Activity
The Delaware system is still in its mixed early-June window. Local public conditions checked for context support sulphurs, Gray Fox, March Browns, Isonychia, tan or gray caddis, olives, some Green Drakes and Coffin Flies, and sulphur or rusty spinners near dark. Bright or stormy weather can break the day into short windows; watch for caddis and mayfly activity in riffle chop before committing to flat-water fish.
| Hatch | Size | Notes |
|---|---|---|
| Dark Blue Winged Olive | 18-22 | Useful in shade, chop, or cloudy periods when fish ignore larger mayflies |
| March Brown / Gray Fox | 10-14 | Good searching profile for riffles, pool heads, and bankside seams |
| Sulphur / Light Cahill | 14-18 | Carry emergers, duns, and spinners for softer water and low light |
| Isonychia | 10-12 | Nymphs and wets are useful in faster seams before visible surface feeding develops |
| Tan or Gray Caddis | 14-18 | Fish pupa, soft hackles, or adults around riffles and evening activity |
| Green Drake / Coffin Fly | 8-10 | Worth carrying near dusk, but match smaller rise forms if fish are on sulphurs or olives |
| Rusty or Sulphur Spinner | 10-20 | Most important on calm slicks and tailouts before weather disrupts the evening |
Recommended Flies
| Category | Fly | Size | Notes |
|---|---|---|---|
| Dry | March Brown or Gray Fox Comparadun | 10-14 | Use as a visible searching dry in broken water before a specific hatch takes over |
| Dry | Sulphur Sparkle Dun or Spinner | 14-18 | Primary late-day mayfly choice in softer seams and tailouts |
| Dry | Elk Hair Caddis or Spent Caddis | 14-18 | Good around riffles when caddis are moving or spent |
| Dry | Green Drake or Coffin Fly | 8-10 | Keep ready for dusk without forcing it over smaller feeding fish |
| Dry | Rusty Spinner | 10-20 | Use a long leader and careful reach casts on calm spinner lanes |
| Nymph | Isonychia Nymph | 10-12 | Work riffles, pocket seams, and pool heads during brighter periods |
| Nymph | Caddis Pupa | 14-18 | Dead drift or swing through riffle tails and edge seams |
| Wet | Partridge and Yellow or Leadwing Coachman | 12-16 | Swing when bugs are present but rises are scattered |
| Streamer | Small Olive Sculpin | 4-8 | Best early, late, or under a storm-darkened sky if visibility is good |
Tactics
Start by watching slow pools and soft bank water before wading. If you see steady noses, match the rise form first; if not, prospect riffles with a larger mayfly dry, a dry-dropper, caddis pupa, Isonychia nymph, or soft hackle. Afternoon storms can turn a good fishing window into a safety problem quickly, so keep an exit route in mind and do not stay on open water through thunder. If the evening clears, slow down and sort out whether fish are on sulphurs, caddis, olives, drakes, or spinners before changing flies repeatedly.
