Upper Delaware, New York
West Branch Delaware Fishing Report: August 1, 2026
The West Branch remains the practical New York trout choice, with a 500 cfs Cannonsville release, cold Hale Eddy water, and current local context pointing to upper-river sulphurs and olives.
- Status
- good
- Flow trend
- stable
- Best window
- Midday sulphurs on the upper river, then check evening spinner water
- Best methods
- dry flies, wet flies, nymphs
Quick Summary
The West Branch is still the best trout option in the active New York report set. USGS showed 607 cfs, 2.96 feet, and 48.6 F at Hale Eddy near the morning check, and the current Delaware-system report lists the Cannonsville release at 500 cfs. Expect the same summer tailwater pattern: sulphurs and smaller olives on the upper river around midday, a few Isonychias mixed in, and more reliable subsurface work lower on the West Branch where algae is less of a problem. Wading is limited rather than easy at this flow, so pick known edges and skip long crossings.
Conditions Snapshot
| Field | Value |
|---|---|
| Status | Good. Cold, controlled tailwater water is fishable and current local context keeps the West Branch in the lead among New York trout options |
| Flow | 607 cfs at Hale Eddy near the morning USGS check; Cannonsville release reported at 500 cfs |
| Gauge Height | 2.96 feet at Hale Eddy |
| Water Temp | 48.6 F at Hale Eddy |
| Clarity | Not reported by official gauges; current Delaware-system context reports the West Branch fishable while freestones continue recovering from the storm pulse |
| Trend | Mostly stable to slowly falling after the late-July rain event |
| Best Window | Late morning through early afternoon on upper-river sulphurs and olives; recheck evening spinner flats if clouds hold |
| Best Method | Dry flies and emergers on the upper West Branch, soft hackles during active bugs, and lighter nymph rigs on cleaner lower-river seams |
| Wadeability | Limited. A boat gives better coverage, and waders should stay with soft edges and familiar footing |
Weather
For Hancock and Hale Eddy, the National Weather Service forecast calls for areas of early fog, mostly cloudy skies, a high near 84 F, and light south wind around 0-5 mph. Tonight stays mostly cloudy with a low near 63 F. Sunday brings a better rain and thunderstorm chance, so today's window is the cleaner weather day before another unsettled stretch.
River Notes
This is a cold tailwater report, not a blanket green light for every Delaware-system trout water. The West Branch has the release and temperature cushion; the freestones are still coming down from the same storm that pushed the Beaverkill and Willowemoc into flood conditions earlier in the week. On the upper West, plan around technical dry-fly water and expect algae to make heavy nymphing frustrating. If surface activity stalls, move to broken seams lower on the West Branch or wait for better light instead of forcing drifts through flat, bright water. Carry a thermometer if you leave the upper tailwater and stop targeting trout if any lower-river reading approaches 68 F.
Hatch Activity
Official gauges do not report hatches. Current Delaware-system reporting and early-August tailwater timing support sulphurs as the main upper West Branch bug, with small olives, Isonychias, tan caddis, Light Cahills, spinners, and terrestrials still worth carrying.
| Hatch | Size | Notes |
|---|---|---|
| Sulphur | 16-20 | Primary daytime hatch on the upper West Branch; smaller patterns remain important |
| Blue Winged Olive | 16-24 | Carry small duns and emergers for softer light or fish that refuse sulphurs |
| Isonychia | 10-14 | Sporadic larger mayfly for riffle edges and searching wet flies |
| Tan Caddis | 16-20 | Pupa, soft hackles, and adults belong in the box for broken water |
| Light Cahill | 14-16 | Evening option if water temperature and light stay favorable |
| Rusty and Sulphur Spinners | 16-24 | Last-light option on flats and slower pools |
| Ants and Beetles | 14-20 | Summer bank-side backup between hatches |
Recommended Flies
| Category | Fly | Size | Notes |
|---|---|---|---|
| Dry | Sulphur Sparkle Dun, Comparadun, or CDC Emerger | 16-20 | Main upper-river pattern set for the midday hatch |
| Dry | BWO Comparadun or CDC Dun | 18-24 | Use when fish switch smaller in shade, slicks, or cloudy periods |
| Dry | Isonychia Parachute or Comparadun | 10-14 | Larger searching dry for faster edges |
| Dry | Elk Hair Caddis or X-Caddis | 16-20 | Prospecting option between mayfly pushes |
| Dry | Rusty Spinner or Sulphur Spinner | 16-24 | Keep ready for evening flats if fish settle in |
| Dry | Ant or Beetle | 14-20 | Summer terrestrial for bank-side fish under brighter light |
| Wet | Soft Hackle Sulphur or Soft Hackle Pheasant Tail | 14-18 | Swing just under the surface when bugs are active but rises are inconsistent |
| Nymph | Pheasant Tail, Frenchie, or Split-Back Mayfly | 14-18 | Better lower on the West Branch where algae is less limiting |
| Nymph | Isonychia Nymph | 10-12 | Useful in riffle edges and faster slots |
Tactics
Start on the upper West Branch if you want dry-fly water and cold temperatures. Use a long leader, place the first cast carefully, and be ready to change from a dun to an emerger or soft hackle when fish show but do not commit cleanly. If you nymph, keep the rig simple and avoid the algae-heavy upper-river stretches where every drift turns into maintenance. Watch footing at 607 cfs, stay out of mid-river crossings, and keep an eye on Sunday storms if you are planning a second-day trip.
