West Branch Delaware Fishing Report: August 6, 2026

Quick Summary

The West Branch is in good summer shape this morning, but today's weather deserves attention. USGS showed 648 cfs, 3.0 feet, and 50.2 F at Hale Eddy during the morning report check, a little lower than yesterday and essentially leveling into a good early-August flow. Current Upper Delaware source context reports a 500 cfs Cannonsville release, steady midday sulphurs around Deposit, some small olives, Isonychias, and Cahills, plus algae on the upper river that makes dry flies and wets cleaner choices than heavy nymphing. Fish the cold tailwater with confidence, but watch the radar as afternoon showers and thunderstorms develop.

Conditions Snapshot

Field	Value
Status	Good. The river is cold, at a useful summer level, and fishable before storms become a factor
Flow	648 cfs at Hale Eddy during the morning report check
Gauge Height	3.0 feet at Hale Eddy
Water Temp	50.2 F at Hale Eddy
Clarity	Not reported by official gauges; current local context describes the Delaware flows as leveling and at a good August level
Trend	Stable to slightly falling from yesterday morning's 695 cfs report check
Best Window	Midday sulphurs on the upper West Branch, then shaded banks and flats before storms
Best Method	Dry flies, emergers, and wet flies first; nymph the lower West where algae is less limiting
Wadeability	Limited to fair. Pick stable edges and avoid casual mid-channel crossings

Weather

For Hancock and Hale Eddy, the National Weather Service forecast calls for partly sunny weather with a high near 87 F and southwest wind up to 5 mph. Showers and thunderstorms become likely this afternoon, with a 70 percent precipitation chance and another chance of storms tonight. The cold tailwater temperature is favorable for trout, but lightning and fast runoff from localized storms are the practical safety concerns today.

River Notes

The West Branch is settling into a strong summer level below Cannonsville. At 648 cfs at Hale Eddy, it is friendly for drift boats and gives careful wading options along softer margins, but it is not a low-water creek crossing situation. Start higher in the tailwater if you want the coldest water and the midday sulphur program. If you fish below Oquaga Creek or on lower river seams, use the current breaks, inside bends, and shaded banks where trout can feed without fighting the main push.

Water temperature remains the best part of this report: 50.2 F at Hale Eddy gives trout a wide buffer against today's warm air. That buffer does not automatically apply to nearby freestones or warmer Delaware sections. Carry a thermometer if you leave the cold tailwater 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 around midday, small Blue Winged Olives mixed in, scattered Isonychias and Cahills, tan caddis, and spinner/terrestrial possibilities around softer light. Because algae remains a nuisance up top, keep the surface and near-surface program ready before committing to bottom-heavy rigs.

Hatch	Size	Notes
Sulphur	16-20	Main reported summer hatch on the upper West Branch; carry duns, emergers, cripples, and spinners
Blue Winged Olive	18-24	Small olives may be mixed into the sulphurs, especially in cloud cover and storm light
Isonychia	10-14	Useful as a wet, nymph, or searching dry along faster riffle edges
Tan Caddis	16-20	Pupa and soft hackles are good when rises are scattered
Light Cahill	14-16	Carry for evening or lower-light bank seams if storms hold off
Rusty and Sulphur Spinners	16-24	Worth having near last light only if lightning is not in the area
Ants and Beetles	14-20	Good summer backup along grass, undercuts, and shaded bank cover

Recommended Flies

Category	Fly	Size	Notes
Dry	Sulphur Sparkle Dun, Comparadun, or CDC Emerger	16-20	First choice during the upper-river sulphur window
Dry	BWO Comparadun or CDC Olive	18-24	Match the smaller olives mixed into the hatch
Dry	Isonychia Parachute or Light Cahill	10-16	Good searching dry when fish are not locked on sulphurs
Dry	Ant or Beetle	14-20	Bank pattern for warm, humid August afternoons
Wet	Soft Hackle Sulphur or Soft Hackle Pheasant Tail	14-18	Swing under the film when adults are present but rises are not steady
Nymph	Pheasant Tail, Frenchie, or Perdigon	14-18	Use on cleaner lower-West seams if algae limits upper-river nymphing
Nymph	Isonychia Nymph	10-12	Work riffles and faster edges with enough weight to tick bottom
Streamer	Small Sculpin or Woolly Bugger	6-10	Backup for storm-stained edges, shade, or bank-oriented fish

Tactics

Treat the upper West as a technical dry-fly river first. Watch the film around midday for sulphurs and olives, then rotate through emerger, cripple, dun, and spinner profiles before changing water. If fish are feeding just below the surface, swing soft hackles or fish a small wet behind a dry instead of dredging through algae. Nymphing is a better choice lower on the West where rigs stay cleaner. Storms are the limiting factor today: leave open water immediately if thunder is near, and be cautious around any quick color change or floating debris after a heavy cell.
