Upper Delaware, New York
West Branch Delaware Fishing Report: July 25, 2026
The West Branch is steady, cold, and fishable around Hale Eddy, with a 500 cfs Cannonsville release, reliable sulphur activity, and limited but useful wading.

- stable
- Best window
- Midday sulphurs near Deposit, then late afternoon into evening
- Best methods
- dry flies, wet flies, nymphs
Quick Summary
The West Branch is the strongest trout option in this New York set this morning. USGS showed 576 cfs, 2.90 feet, and 46.6 F at Hale Eddy during the morning check, while current Delaware-system context continues to show a 500 cfs Cannonsville release and a good level for both floating and careful wading. Expect the most consistent dry-fly window around the upper West Branch when sulphurs and olives start, with wets or nymphs as backups in cleaner lower-river seams. The water is cold and fishable, but the day warms quickly, so keep the lower river and any mainstem trout fishing temperature-aware.
Conditions Snapshot
| Field | Value |
|---|---|
| Status | Good. Cold tailwater temperature, steady release flow, and current hatch context make this a useful July fishing window |
| Flow | 576 cfs at Hale Eddy during the morning USGS check |
| Gauge Height | 2.90 feet at Hale Eddy |
| Water Temp | 46.6 F at Hale Eddy |
| Clarity | Upper tailwater reported off-color after storms in parts of the drainage; official gauges do not report clarity |
| Trend | Stable compared with yesterday morning at Hale Eddy |
| Best Window | Midday sulphurs near Deposit, then late afternoon into evening if wind stays light |
| Best Method | Dry flies and emergers during sulphur and olive activity; wets or nymphs in cleaner seams if fish are not rising |
| Wadeability | Limited. Work known edges, bars, and softer crossings only; boats still cover this flow more comfortably |
Weather
For Hancock and Hale Eddy, the National Weather Service forecast calls for sunny skies with a high near 83 F and light southeast wind around 0 to 5 mph. Tonight should be mostly clear with a low around 54 F. Light wind helps presentation on slow pools, but bright sun can make fish selective and can warm downstream trout water away from the cold release.
River Notes
The release is holding the West Branch in a consistent summer tailwater shape. Hale Eddy is only slightly lower than yesterday morning, so boat timing, wade access, and hatch timing should not need major adjustment. Current local context points to daytime sulphurs around Deposit, small olives mixed in, and some Isonychias and Cahills in faster water. Algae remains a practical issue on parts of the upper river when fishing subsurface, so do not spend the best hatch period cleaning nymphs if fish are willing to rise. If the top end is dirty from recent storms, slide to clearer water, fish shorter accurate dry-fly drifts to visible feeders, or use soft hackles and sparse nymph rigs on the lower West Branch.
Hatch Activity
Official gauges do not report hatches. Current Delaware-system reporting and late-July tailwater timing support sulphurs, small olives, Isonychias, tan caddis, Light Cahills, sulphur spinners, rusty spinners, and terrestrials. Smaller sulphur and olive patterns should be ready first on the flats, with Isonychia and caddis profiles better for riffle edges and broken seams.
| 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 the sulphurs, especially in softer light or shaded slicks |
| Isonychia | 10-14 | Useful in riffles and faster edges; also a good 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/searching mayfly for broken water |
| Sulphur and Rusty Spinners | 16-24 | Worth carrying near dark if wind stays down |
| Ants and Beetles | 14-20 | Good bank-side backup during quiet periods or bright sun |
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 on calm slicks |
| 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
Start by watching before rigging. If sulphurs or olives are moving, fish one accurate dry or a dry with a small emerger dropper and use enough leader to handle slow slicks. If the surface is quiet, swing soft hackles through riffle tails or shift to the lower West Branch with a sparse nymph rig where algae is less likely to foul every drift. Keep wading conservative around 575 cfs, avoid long pushy crossings, and give drift boats room in narrower channels.
