Quick Summary
The West Branch is the best New York trout option in this morning's set. USGS showed 653 cfs, 3.05 feet, and 49.1 F at Hale Eddy during the morning check, and current Upper Delaware source context reports a 549 cfs Cannonsville release with the West Branch in good shape. The river is cold, clear, and very fishable, but wading is still deliberate rather than casual at Hale Eddy. Expect the cleanest dry-fly opportunity around shaded water, morning edges, and the late-day window; nymph the lower West Branch if you need to go underneath because algae remains a problem up top.
Conditions Snapshot
| Field | Value |
|---|---|
| Status | Good. Cold tailwater water, clear reported conditions, and current hatch activity make this a useful day on the West Branch |
| Flow | 653 cfs at Hale Eddy during the morning check |
| Gauge Height | 3.05 feet at Hale Eddy |
| Water Temp | 49.1 F at Hale Eddy |
| Clarity | Not reported by official gauges; current local context reports clear water on the West Branch |
| Trend | Falling modestly compared with yesterday morning |
| Best Window | Morning shade, careful mid-day sight fishing, then late afternoon into evening |
| Best Method | Dry flies and emergers for olives, flying ants, Hebes, Isonychias, Cahills, and tan caddis; wet flies or light nymphs where algae is not fouling the drift |
| Wadeability | Limited. Use known gravel, softer edges, and conservative crossings; boats have the simpler river coverage |
Weather
For Hancock and Hale Eddy, the National Weather Service forecast calls for patchy fog early, then sun with a high near 76 F and a light northwest wind around 0 to 5 mph. Tonight should be partly cloudy with a low near 55 F. The light wind helps small dry-fly presentations, but full sun can make fish more selective until shade or evening light returns.
River Notes
Hale Eddy is down slightly from yesterday morning and remains in a comfortable tailwater range. The cold release keeps trout temperatures safely below the 68 F stress line, while the moderate flow gives fish cover along banks, riffle edges, slicks, and foam seams. Wade anglers should still move carefully and avoid making crossings just because the gauge is lower than yesterday.
Current Upper Delaware source context says the West Branch is in good shape while the other rivers are dropping and clearing after Thursday night's rain. That supports a dry-fly-first plan. If the upper river algae dirties nymphs every few casts, do not force it; fish dries, wets, or move lower where subsurface presentations stay cleaner.
Hatch Activity
Official gauges do not report hatches. Current Upper Delaware source context supports Blue Winged Olives, Hebes, flying ants, Isonychias, Cahills, tan caddis, and a few late Sulphurs.
| Hatch | Size | Notes |
|---|---|---|
| Blue Winged Olive | 16-24 | Carry both #16-18 olives and smaller technical patterns for slick water |
| Hebe | 18-20 | Useful during late-summer small-mayfly activity, especially in shade or softer light |
| Flying Ant | 18-24 | A key late-summer option for banks, foam lines, and fish that ignore mayfly profiles |
| Isonychia or Slate Drake | 10-14 | Search riffle edges and banks with dries, wets, or swimming nymphs |
| Light Cahill or Summer Steno | 14-16 | Keep ready for larger evening mayflies and mixed rise forms |
| Tan Caddis | 16-20 | Fish pupa, soft hackles, or sparse dries around riffles and shaded seams |
| Sulphur | 16-20 | Fading, but still possible enough to keep a few in the box |
Recommended Flies
| Category | Fly | Size | Notes |
|---|---|---|---|
| Dry | BWO Comparadun, CDC Olive, or olive emerger | 16-24 | Use for shaded slicks, slow seams, and small olive feeders |
| Dry | Flying Ant, Hebe, or small beetle | 18-24 | Fish tight to banks, foam seams, and quiet tailouts |
| Dry | Isonychia Parachute, Slate Drake, Light Cahill, or Summer Steno | 10-16 | Cover broken banks and mixed evening hatches |
| Wet | Soft Hackle Pheasant Tail, Isonychia Wet, or partridge soft hackle | 12-18 | Swing riffle tails and bank seams when rises are scattered |
| Nymph | Pheasant Tail, Frenchie, caddis pupa, or Isonychia Nymph | 12-20 | Best on the lower West Branch or other cleaner lanes; check often for algae |
| Streamer | Small olive or black sculpin, Woolly Bugger, or sparse baitfish pattern | 4-8 | Worth a short low-light test from a boat or along undercut banks |
Tactics
Start by looking for ants, olives, and small rise forms before adding weight. A long leader, reach cast, and single dry or dry-and-emerger setup will cover the most technical water. In broken banks and riffle tails, an Isonychia dry or wet fly can search without dragging a nymph rig through algae. If you nymph, stay lower, keep the rig light, and clean the flies often.
