- good
- Flow trend
- stable
- Best window
- Midday into early evening on the cold tailwater, with a weather check before afternoon storms
- Best methods

Quick Summary
The West Branch remains the best New York trout option in this report set. USGS showed 663 cfs, 3.07 feet, and 50.7 F at Hale Eddy during the morning report check, only a small bump from yesterday and still a useful summer level for drift boats and careful edge wading. Current Upper Delaware source context keeps the upper tailwater in the better shape than the freestones, with sulphurs, small Blue Winged Olives, Isonychias, Cahills, and spinner possibilities. Fish the cold water first, but treat afternoon thunderstorms as the limiting factor.
Conditions Snapshot
| Field | Value |
|---|---|
| Status | Good. Cold water and a steady summer flow make the West Branch fishable, with weather as the main constraint |
| Flow | 663 cfs at Hale Eddy during the morning report check |
| Gauge Height | 3.07 feet at Hale Eddy |
| Water Temp | 50.7 F at Hale Eddy |
| Clarity | Not reported by official gauges; current local context points anglers toward the upper tailwater for the best wading and dry-fly opportunity |
| Trend | Stable to slightly rising from yesterday morning's 648 cfs report check |
| Best Window | Midday sulphurs and olives on the upper West Branch, then lower-light seams if storms stay away |
| Best Method | Dry flies and emergers when fish show; wet flies and light nymph rigs before the hatch builds |
| Wadeability | Limited. Work stable edges and do not make casual mid-channel crossings |
Weather
For Hancock and Hale Eddy, the National Weather Service forecast calls for patchy morning fog giving way to mostly sunny weather, a high near 87 F, and light west wind. Showers and thunderstorms are possible later in the day, with a 50 percent precipitation chance. The tailwater temperature is favorable for trout, but lightning and quick color changes below storm cells should decide when to leave the river.
River Notes
At 663 cfs, the West Branch is not low, but it is in a practical summer range. Boats have enough water, and careful waders can fish selected edges, inside bends, and softer tailouts without forcing crossings. The cold Hale Eddy temperature gives trout a strong buffer against today's warm air, especially above and around the stronger tailwater influence.
Start high if you want the most dependable temperature and surface-feeding program. Local source context this morning still favors the tailwaters over the Beaverkill and Willowemoc while those freestones rise from rain. If you fish lower on the West Branch, keep an eye on stain, debris, and any fresh runoff from afternoon storms. Carry a thermometer if you leave the cold-water influence, and stop targeting trout anywhere readings approach 68 F.
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, and evening spinner possibilities. With rain and cloud cover around, keep small olives and wet flies handy even if the main target is the sulphur window.
| Hatch | Size | Notes |
|---|---|---|
| Sulphur | 16-20 | Main upper-West hatch; carry duns, emergers, cripples, and spinners |
| Blue Winged Olive | 18-24 | Useful in cloud cover, light rain, and mixed surface activity |
| Isonychia | 10-14 | Good searching profile in riffles and faster bank seams |
| Light Cahill | 14-16 | Worth carrying for late-day riffle water if storms hold off |
| Tan Caddis | 16-18 | Pupa and soft hackles can cover water before steady rises begin |
| Rusty and Sulphur Spinners | 16-24 | Last-light option only if lightning is not in the area |
| Ants and Beetles | 14-20 | Good summer bank pattern around grass, shade, and undercuts |
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 | 18-24 | Match the small olives during cloud cover or light rain |
| Dry | Isonychia Parachute or Light Cahill | 10-16 | Useful searching dries in faster riffle seams |
| Dry | Ant or Beetle | 14-20 | Fish tight to shaded grass, undercuts, and bank cover |
| 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 the hatch or where fish are not looking up |
| Nymph | Isonychia Nymph | 10-12 | Work riffle edges and faster seams with a controlled swing at the end |
| Streamer | Small Sculpin or Woolly Bugger | 6-10 | Backup for stained edges after rain or during low light |
Tactics
Watch the water before rigging heavy. If sulphurs or olives are present, fish a single dry, an emerger, or a dry with a small wet dropper before switching to bottom rigs. During quiet periods, cover broken seams with soft hackles or a light nymph rig, then move slowly between feeding lanes instead of forcing long wades. Thunder ends the session: leave open water immediately if you hear it, and be cautious below tributaries if a storm cell adds color or floating debris.
