Upper Delaware, New York
West Branch Delaware Fishing Report: August 8, 2026
The West Branch is cold, clear enough, and fishable at Hale Eddy, with sulphurs and small olives still worth planning around before afternoon thunderstorms become the main limiter.
- Status
- good
- Flow trend
- falling
- Best window
- Midday on the upper cold tailwater, then selected evening water if storms stay away
- Best methods
- dry flies, wet flies, nymphs
Quick Summary
The West Branch remains the strongest New York trout option in this morning's report set. USGS showed 684 cfs, 3.11 feet, and 51.4 F at Hale Eddy during the 9 AM refresh, down slightly from the first-pass check and still in a practical summer range for drift boats and careful edge wading. Current Upper Delaware source context reports a 500 cfs Cannonsville release, usable clarity, midday sulphurs on the upper West Branch, and small olives, Isonychias, Cahills, caddis, and terrestrials in the mix. Fish the cold tailwater first, treat the upper algae as a reason to stay with dries when fish are up, and leave room in the plan for scattered afternoon thunderstorms.
Conditions Snapshot
| Field | Value |
|---|---|
| Status | Good. Cold tailwater temperature and a moderate Hale Eddy flow keep the river fishable, with thunderstorms as the main safety constraint |
| Flow | 684 cfs at Hale Eddy during the 9 AM refresh |
| Gauge Height | 3.11 feet at Hale Eddy |
| Water Temp | 51.4 F at Hale Eddy |
| Clarity | Not reported by official gauges; current local context reports fishable clarity on the West Branch |
| Trend | Falling slightly from the first-pass check, from 689 cfs to 684 cfs |
| Best Window | Midday on the upper West Branch for sulphurs and olives; evening only if lightning is not nearby |
| Best Method | Dry flies and emergers on the upper river when fish show; nymph the lower West Branch during quiet periods |
| Wadeability | Limited to selected edges, inside bends, and stable gravel. Boats remain a good option |
Weather
For Hancock and Hale Eddy, the National Weather Service forecast calls for patchy morning fog giving way to a partly sunny day, a high near 82 F, southwest wind around 6 mph, and scattered showers and thunderstorms developing from midday through afternoon. Rainfall amounts are forecast to stay light in most cells, but any thunderstorm can bring lightning, short-term color changes, and floating debris. The water temperature is favorable for trout; the weather window is the risk to manage.
River Notes
At 684 cfs, the West Branch has enough water for boats and enough shape for careful waders who stay disciplined. Focus on soft seams, inside bends, bank edges, and tailouts rather than forcing broad crossings. The cold Hale Eddy temperature gives trout a strong summer buffer, especially above and around the stronger tailwater influence.
Upper-river dry-fly water is the best starting point if you want surface activity, but local context now points to algae as a practical nuisance up top. Keep that reach simple with dries, emergers, and spinners when fish are feeding, then move to the lower West Branch if you want to nymph during slower periods. Local context continues to favor the West Branch over the warm Catskill freestones for daytime trout fishing. If you move downstream or fish below tributary influence, keep a thermometer handy and watch for stain from storms. Stop targeting trout anywhere readings approach 68 F, and get off the water immediately if thunder is close.
Hatch Activity
Official gauges do not report hatches. Current Upper Delaware source context supports summer sulphurs on the upper West Branch, small Blue Winged Olives, Isonychias, Light Cahills, tan caddis, tricos in the morning, and terrestrial patterns along banks. Cloud cover and showers can help the small-olive and wet-fly bite, but lightning should end the session.
| Hatch | Size | Notes |
|---|---|---|
| Sulphur | 16-20 | Main upper-tailwater target; carry duns, emergers, cripples, and spinners |
| Blue Winged Olive | 16-24 | Good match for cloud cover, showers, and mixed surface feeding |
| Isonychia | 10-14 | Useful as a searching dry, wet fly, or nymph in faster seams |
| Light Cahill | 14-16 | Carry for late-day riffle activity if storms miss the river |
| Tan Caddis | 16-20 | Pupa and soft hackles can cover water before steady rises begin |
| Trico | 20-24 | Morning option in slow flats when fish are set up and the wind is manageable |
| Ants and Beetles | 14-20 | Good summer bank option around grass, shade, and undercut edges |
Recommended Flies
| Category | Fly | Size | Notes |
|---|---|---|---|
| Dry | Sulphur Sparkle Dun, Comparadun, or CDC Emerger | 16-20 | Primary choice during the upper-tailwater hatch window |
| Dry | BWO Comparadun or CDC Olive | 16-24 | Use during cloud cover, showers, and small-ring rises |
| Dry | Trico Spinner | 20-24 | Morning flat-water pattern when fish are working tiny bugs |
| Dry | Isonychia Parachute or Light Cahill | 10-16 | Searching profile for riffle seams and broken water |
| Dry | Ant or Beetle | 14-20 | Fish close to shaded banks, grass, and undercuts |
| Wet | Soft Hackle Sulphur or Soft Hackle Pheasant Tail | 14-18 | Swing under the film when fish feed just below the surface |
| Nymph | Pheasant Tail, Frenchie, or Perdigon | 14-18 | Use before bugs show or in seams without visible rises |
| Nymph | Isonychia Nymph | 10-12 | Work riffle edges and faster banks with a controlled swing at the end |
| Streamer | Small Sculpin or Woolly Bugger | 6-10 | Backup for stained edges after rain or low-light pushes |
Tactics
Start by watching for surface rhythm before rigging heavy. If sulphurs, olives, or tricos are on the water, use a long leader, accurate fly-first presentation, and a single dry or emerger rather than repeated false casts over feeding fish. Keep upper-river nymph rigs to a minimum if algae is fouling flies; if you need a subsurface program, use the lower West Branch seams with a light nymph rig or soft hackle and move deliberately instead of wading through good water. Check radar often after lunch; if thunder is audible or a storm puts color into a tributary, end the session.
