Quick Summary
The West Branch is still the strongest New York trout option in this morning's report set. USGS showed 658 cfs, 3.06 feet, and 48.7 F at Hale Eddy during the 8 AM check, which is nearly unchanged from yesterday and keeps the tailwater cold and fishable. Current Upper Delaware source context reports a 549 cfs Cannonsville release, dense morning fog, sun after the fog breaks, olives, Cahills, Isonychias, flying ants, and sulphurs that are getting spottier as the hatch winds down. Wade with restraint at this level, and treat the upper West as mostly a dry-fly and wet-fly game where algae makes heavy nymphing less efficient.
Conditions Snapshot
| Field | Value |
|---|---|
| Status | Good. Cold tailwater temperature, steady release-supported flow, and current bug activity give anglers a real shot; algae and selective late-summer trout are the main limits |
| Flow | 658 cfs at Hale Eddy during the 8 AM check |
| Gauge Height | 3.06 feet at Hale Eddy |
| Water Temp | 48.7 F at Hale Eddy |
| Clarity | Not reported by official gauges; current local context does not indicate a blowout or major clarity problem |
| Trend | Stable to slightly lower compared with yesterday morning |
| Best Window | Late morning through afternoon after fog lifts; check again during evening soft light |
| Best Method | Dry flies, emergers, and soft hackles first; nymph the lower West where algae is less likely to foul the rig |
| Wadeability | Limited. Fish known bars, softer edges, and controlled crossings rather than forcing mid-river moves |
Weather
For Hancock and Hale Eddy, the National Weather Service forecast calls for areas of fog before 10 AM, then mostly sunny weather with a high near 77 F. Wind should be light from the southeast at 1 to 6 mph. Tonight brings patchy fog and a rising chance of showers and thunderstorms, with the better rain chance arriving overnight into Sunday. Today's light wind helps dry-fly accuracy, but bright sun after the fog burns off may push the best surface work toward shade, riffle edges, foam lines, and any water with visible bug activity.
River Notes
The Hale Eddy gauge is holding in a dependable late-August band. There is enough water for drift boats and bank-to-bank current, but it is still not casual wading water. Move slowly, stay on stable footing, and plan casts from gravel bars, bank edges, and inside seams instead of trying to reach every rise.
Current Upper Delaware source context lines up with the official gauge: the Cannonsville release remains steady at 549 cfs, the West Branch is cold, and the morning fog should give way to brighter conditions. The practical fishing note is still algae on the upper river. If a nymph rig keeps fouling, do not grind through it all morning. Watch slicks and foam lines for heads, blind-cast larger mayfly dries where appropriate, and swing soft hackles through riffle tails or bank seams between surface windows.
Hatch Activity
Official gauges do not report hatches. Current Upper Delaware source context supports Dark Blue Winged Olives, sulphurs, tan caddis, Light Cahills or summer stenos, Isonychias, and flying ants. Sulphurs are fading, but they still matter on the coldest water. Ants remain a key late-summer changeup, especially when fish refuse standard mayfly patterns.
| Hatch | Size | Notes |
|---|---|---|
| Dark Blue Winged Olive | 16-18 | Best in fog, shade, broken light, or slick water with steady sipping fish |
| Sulphur | 16-20 | Spotty and waning, but still worth carrying on the cold upper West Branch |
| Flying Ant | 18-24 | Fish banks, foam seams, and tailouts when trout ignore mayfly profiles |
| Tan Caddis | 16-20 | Useful as pupa, emergers, or small adults in broken current |
| Light Cahill or Summer Steno | 14-16 | Good mixed-hatch dry for afternoon and evening searching |
| Isonychia or Slate Drake | 10-12 | Blind-cast dries, swing wets, or fish nymphs along faster banks and riffle edges |
Recommended Flies
| Category | Fly | Size | Notes |
|---|---|---|---|
| Dry | BWO Comparadun, CDC Olive, or olive emerger | 16-18 | Use when trout work small mayflies in slicks or soft seams |
| Dry | Sulphur Sparkle Dun, CDC Emerger, or Comparadun | 16-20 | Keep a few ready for the coldest upper-river water even as the hatch fades |
| Dry | Flying Ant | 18-24 | Important late-summer changeup around banks, foam, and quiet tails |
| Dry | Isonychia Parachute, Slate Drake, or Light Cahill | 10-16 | Search broken water before trout lock onto smaller flies |
| Wet | Soft Hackle Pheasant Tail, Soft Hackle Sulphur, or Isonychia Wet | 12-18 | Swing through riffle tails and bank seams between surface pushes |
| Nymph | Pheasant Tail, Frenchie, Sulphur Nymph, or Isonychia Nymph | 12-20 | Best on lower-West seams where algae is less of a problem |
Tactics
Start by watching the water. If fog hangs in or fish are already dimpling, fish a long leader with one accurate dry or a dry-and-emerger pair. If there are no steady rises, cover bank seams and riffle tails with an Isonychia dry, Cahill, or soft hackle before adding weight. On the upper West, change method or water if algae keeps fouling the rig. Keep wading conservative at 658 cfs, and use the West Branch as the safer coldwater option if nearby freestones warm toward 68 F later in the day.
