- Status
- good
- Flow trend
- stable
- Best window
- Midday sulphurs near Deposit, then late afternoon into evening before storms
- Best methods
- dry flies, wet flies, nymphs
Quick Summary
The West Branch remains the best trout water in this New York set this morning. USGS showed 576 cfs, 2.90 feet, and 47.1 F at Hale Eddy during the morning check, and current Delaware-system source context continues to show a 500 cfs Cannonsville release. The river is at a workable level for floating and careful edge wading, with the better dry-fly chance around the upper West Branch sulphur water near Deposit. Carry rain gear and watch the sky after midafternoon, because the National Weather Service has scattered shower and thunderstorm chances in the forecast.
Conditions Snapshot
| Field | Value |
|---|---|
| Status | Good. Cold tailwater temperature, steady release flow, and current sulphur activity make this a useful July trout option |
| Flow | 576 cfs at Hale Eddy during the morning USGS check |
| Gauge Height | 2.90 feet at Hale Eddy |
| Water Temp | 47.1 F at Hale Eddy |
| Clarity | Not reported by official gauges; local Delaware context points to fishable water with algae still an issue on parts of the upper river |
| Trend | Stable compared with yesterday morning at Hale Eddy |
| Best Window | Midday sulphurs near Deposit, then late afternoon into evening if storms stay away |
| Best Method | Dry flies and emergers during sulphur and olive activity; wets or nymphs in lower, cleaner seams if fish are not rising |
| Wadeability | Limited. Use known bars, soft edges, and conservative crossings; boats remain the easier way to cover this flow |
Weather
For Hancock and Hale Eddy, the National Weather Service forecast calls for a high near 82 F with partly sunny skies and light south wind around 2 mph. Isolated to scattered showers and thunderstorms are possible from midafternoon into early evening, then areas of fog are possible overnight with a low around 58 F. Light wind helps dry-fly presentation, but any thunderstorm cell can change safety quickly, especially for anglers in drift boats or on open riffles.
River Notes
The West Branch has not changed much from yesterday morning, which is useful news for anglers trying to plan a float or a short wade session. The Hale Eddy gauge is holding near 576 cfs, and the 500 cfs Cannonsville release is keeping the upper tailwater cold enough for full-day trout conditions. Current local reporting points to daytime sulphurs around Deposit, olives mixed in, and a few Isonychias, with smaller patterns still important on slow water. If you need to nymph, favor the lower West Branch or cleaner seams and check flies often; algae remains a practical problem on parts of the upper river. Downstream and mainstem water should still be treated with a thermometer as the afternoon warms.
Hatch Activity
Official gauges do not report hatches. Current Delaware-system reports and late-July tailwater timing support sulphurs, small olives, Isonychias, tan caddis, Light Cahills, spinners, and terrestrials. The upper West Branch sulphur window remains the main dry-fly play, while Isonychia, caddis, and soft hackle profiles cover riffles and transitions when fish are not locked on small duns.
| Hatch | Size | Notes |
|---|---|---|
| Sulphur | 16-20 | Main upper-West Branch hatch; carry duns, emergers, cripples, and soft hackles |
| Blue Winged Olive | 18-24 | Small olives can mix into sulphurs, especially under clouds or in shaded slicks |
| Isonychia | 10-14 | Useful in riffles, broken edges, and as a wet-fly or nymph profile |
| Tan Caddis | 16-20 | Pupa, soft hackles, and adults can cover seams between mayfly pushes |
| Light Cahill | 14-16 | Pale evening or searching mayfly for broken water |
| Sulphur and Rusty Spinners | 16-24 | Worth carrying near dark if wind and thunderstorms allow a calm spinner window |
| Ants and Beetles | 14-20 | Good bank-side backup during bright or quiet periods |
Recommended Flies
| Category | Fly | Size | Notes |
|---|---|---|---|
| Dry | Sulphur Sparkle Dun, Comparadun, or CDC Emerger | 16-20 | Primary match for upper West Branch risers |
| Dry | BWO Comparadun or CDC Dun | 18-24 | Use when fish key on smaller olives mixed with sulphurs |
| Dry | Isonychia Parachute or Comparadun | 10-14 | Larger profile for riffle edges and dry-dropper searching |
| Dry | Elk Hair Caddis or X-Caddis | 16-20 | Small tan caddis option for riffles and seams |
| Dry | Light Cahill or White Wulff | 14-16 | Visible pale dry for evening broken water |
| Dry | Rusty Spinner or Sulphur Spinner | 16-24 | Keep ready for last light if storms do not interrupt the spinner fall |
| Dry | Ant or Beetle | 14-20 | Bank-side option when bright sun slows mayflies |
| Wet | Soft Hackle Sulphur or Soft Hackle Pheasant Tail | 14-18 | Swing through riffle tails during emergences |
| Nymph | Pheasant Tail, Frenchie, or Split-Back Mayfly | 14-18 | Use in cleaner lower-river seams and check for algae often |
| Nymph | Isonychia Nymph | 10-12 | Good larger subsurface choice near riffle edges |
Tactics
Watch the water before committing to a rig. If sulphurs or olives are moving, fish one accurate dry or a dry with a small emerger dropper and lengthen the leader for slow flats. If the surface is quiet, swing soft hackles through riffle tails or nymph the lower West Branch with a sparse rig where algae is less likely to foul every drift. Keep wading conservative around 575 cfs, avoid long pushy crossings, give drift boats room, and leave the water immediately if thunder is close.
