Upper Delaware, New York
West Branch Delaware Fishing Report: August 2, 2026
The West Branch remains the strongest New York trout option, with cold Hale Eddy water, a 500 cfs Cannonsville release, and a practical sulphur-and-olive window before afternoon storms become the main safety issue.
- Status
- good
- Flow trend
- stable
- Best window
- Late morning through early afternoon before thunderstorms build
- Best methods
- dry flies, emergers, nymphs
Quick Summary
The West Branch is still the best choice among the active New York trout reports. USGS showed 591 cfs, 2.93 feet, and 49.6 F at Hale Eddy near the 9 AM refresh, which keeps the upper tailwater cold and fishable while surrounding freestones need more caution. Current local Delaware-system context now points to a 500 cfs Cannonsville release, decent sulphur activity around Deposit, olives mixed in, and some Isonychias and Cahills. Fish the late morning into early afternoon window, then watch the sky closely because the National Weather Service has showers and thunderstorms likely later today and tonight.
Conditions Snapshot
| Field | Value |
|---|---|
| Status | Good. Cold, controlled tailwater water gives anglers a real dry-fly and emerger window, but thunderstorms can shorten the day |
| Flow | 591 cfs at Hale Eddy near the 9 AM USGS refresh; Cannonsville release reported at 500 cfs |
| Gauge Height | 2.93 feet at Hale Eddy |
| Water Temp | 49.6 F at Hale Eddy |
| Clarity | Not reported by official gauges; recent local context described the West Branch as fishable after late-July rain |
| Trend | Stable this morning, with only minor movement from the 8 AM report value of 586 cfs |
| Best Window | Late morning through early afternoon for Deposit-area sulphurs and olives; leave room to get off the water if storms develop |
| Best Method | Small sulphur dries and emergers, BWO dries, soft hackles during active bugs, and light nymph rigs on the lower West Branch |
| Wadeability | Limited. Stay with known edges and controlled steps; a boat gives better coverage at this flow |
Weather
For Hancock and Hale Eddy, the National Weather Service forecast calls for a high near 80 F, mostly cloudy skies early, south wind around 8 mph, and a chance of showers and thunderstorms after 2 PM. Tonight has a much higher thunderstorm chance with a low near 65 F and roughly a quarter to a half inch of possible new rainfall. The morning and early afternoon are the better fishing window; lightning and rapid runoff from localized storms are the main weather constraints.
River Notes
This remains a tailwater-first trout call. The Hale Eddy temperature is comfortably cold for trout, and the flow is in a useful summer range, but it is not low enough to treat the river as easy wading. Start near the upper release influence if you want the best dry-fly water and temperature cushion; if you want to nymph, current local guidance favors the lower West Branch. If the surface bite is slow, fish a small emerger or soft hackle just under the film before going to a heavier nymph rig. Keep an eye on the radar and avoid committing to long floats or remote wades once storms start building.
Hatch Activity
Official gauges do not report hatches. Current Delaware-system reporting and early-August tailwater timing support sulphurs as the anchor hatch on the upper West Branch, especially around Deposit, with small olives, Isonychias, tan caddis, Light Cahills, rusty spinners, and terrestrials still worth carrying.
| Hatch | Size | Notes |
|---|---|---|
| Sulphur | 16-20 | Main upper West Branch hatch, with the most current local emphasis around Deposit; smaller emergers and cripples matter late in the hatch cycle |
| Blue Winged Olive | 18-24 | Good choice under clouds, in soft slicks, or when fish refuse the larger sulphur profile |
| Isonychia | 10-14 | Sporadic larger mayfly for riffle edges, blind casts, and dropper rigs |
| Tan Caddis | 16-18 | Pupa, soft hackles, and adults remain useful in broken water |
| Light Cahill | 14-16 | Evening option if storms miss and light conditions stay favorable |
| Rusty and Sulphur Spinners | 16-24 | Last-light option on flats if weather allows a safe evening session |
| Ants and Beetles | 14-20 | Bank-side summer backup between hatches |
Recommended Flies
| Category | Fly | Size | Notes |
|---|---|---|---|
| Dry | Sulphur Sparkle Dun, Comparadun, or CDC Emerger | 16-20 | Primary upper-river pattern set for the midday hatch |
| Dry | BWO Comparadun or CDC Dun | 18-24 | Use when cloud cover has fish on smaller olives |
| Dry | Isonychia Parachute or Comparadun | 10-14 | Searching fly for faster edge water and sporadic larger rises |
| Dry | Elk Hair Caddis or X-Caddis | 16-18 | Good prospecting profile between mayfly pushes |
| Dry | Rusty Spinner or Sulphur Spinner | 16-24 | Carry for evening flats only if storms stay away |
| Dry | Ant or Beetle | 14-20 | Useful along shaded banks in summer tailwater conditions |
| Wet | Soft Hackle Sulphur or Soft Hackle Pheasant Tail | 14-18 | Swing just under the surface when bugs are active but rises are uneven |
| Nymph | Pheasant Tail, Frenchie, or Split-Back Mayfly | 14-18 | Use in broken seams where algae is manageable |
| Nymph | Isonychia Nymph | 10-12 | Good anchor profile in riffles and faster slots |
Tactics
Start with a dry-fly or emerger plan on the upper West Branch, especially if clouds keep the water from getting too bright and sulphurs show around Deposit. Use a long leader, make the first cast count, and switch between dun, emerger, cripple, and soft hackle profiles before changing pools. If you nymph, keep it light and favor lower-West broken seams instead of dragging through algae-heavy flat water. Do not ignore the weather: thunderstorm risk is high enough that the safest plan is a shorter session with an easy exit route.
