West Branch Delaware Fishing Report: July 5, 2026

Quick Summary

The West Branch remains fishable and cold this morning while the nearby freestones are already too warm for responsible trout fishing. USGS showed 561 cfs and 48.4 F at Hale Eddy, with Stilesville at 516 cfs and 45.7 F during the morning check. Flows have stepped down from yesterday, so wading is more approachable along known edges but still not a reason to push into heavy current. Fish the cold tailwater before storms build, then use any safe evening clearing for sulphurs, olives, Cahills, caddis, and spinners.

Conditions Snapshot

Field	Value
Status	Good on the cold tailwater, with falling flows, limited wading, and afternoon/evening thunderstorm risk
Flow	561 cfs at Hale Eddy; 516 cfs at Stilesville
Gauge Height	2.87 feet at Hale Eddy; 8.09 feet at Stilesville
Water Temp	48.4 F at Hale Eddy; 45.7 F at Stilesville during the morning USGS check
Clarity	Not reported by official gauges; cold release water is the key advantage today
Trend	Falling from yesterday morning, with enough release water to keep the West Branch protected from the July heat
Best Window	Morning through early afternoon before storms, then any safe evening clearing or spinner window
Best Method	Nymphs, wet flies, and dry-dropper rigs until fish show; technical dries, emergers, and spinners when surface feeding develops
Wadeability	Limited to improving. Use known gravel and soft edges, and stay out of fast mid-channel current

Weather

For Hancock and Hale Eddy, the National Weather Service forecast calls for fog early, a high near 83 F, light wind, and showers or thunderstorms becoming likely this afternoon. Tonight brings a higher chance of rain and storms, with more unsettled weather into Monday. The low wind helps dry-fly fishing, but lightning and quick local runoff are the main safety constraints. Have a short exit route if you fish long flats, islands, or steep banks.

River Notes

The West Branch is the clear trout option in the New York set today because the release water is keeping temperatures safely cold. The river is lower than yesterday, which should make some edges easier to approach, but the best fishing will still be in cold, covered water rather than warm neighboring reaches. Falling water can make fish slide off bank seams and settle into defined lanes, shelves, and softer riffle edges. If the afternoon storms arrive, leave exposed water early and do not move to the Beaverkill or other freestones for trout just because clouds appear.

Hatch Activity

Recent Upper Delaware local context and early-July seasonality continue to support sulphurs, small olives, Isonychias, Light Cahills, tan caddis, dark sedges, terrestrials, and evening spinners. Expect the most dependable surface work under fog, clouds, rain-softened light, or evening shade rather than under bright midday sun.

Hatch	Size	Notes
Sulphur	16-20	Main cold-tailwater mayfly; carry duns, emergers, cripples, and soft hackles
Blue Winged Olive	18-24	Best in fog, cloud cover, light rain, or the storm-softened window
Isonychia	10-12	Nymphs and swung wets can cover riffle edges and faster bank water
Light Cahill	14-16	Useful evening searching dry when pale bugs are mixed
Tan Caddis	16-20	Pupa and low-riding adults can fill gaps before steady mayfly activity
Dark Blue Sedge	14	Darker caddis or skated patterns can matter in broken evening water
Ants and Beetles	14-18	Worth carrying for shaded banks if hatch activity stalls
Rusty Spinner	14-20	Keep ready for last light if thunderstorm wind does not break up the fall

Recommended Flies

Category	Fly	Size	Notes
Dry	Sulphur Comparadun, Usual, or Sparkle Dun	16-20	Primary dry when fish key on pale mayflies
Dry	BWO Comparadun or CDC Dun	18-24	Use during fog, clouds, light rain, or low light
Dry	Light Cahill or White Wulff	14-16	Visible pattern for scattered evening fish
Dry	Rusty Spinner	14-20	For flat-water sippers near last light
Dry	Ant or Beetle	14-18	Good shaded-bank option if bugs are sparse
Nymph	Pheasant Tail, Frenchie, or Split-Back Mayfly	14-18	Fish under a dry or lightly weighted through softer seams
Nymph	Isonychia Nymph	10-12	Work riffle edges and let the fly finish on a controlled swing
Wet	Soft Hackle Pheasant Tail or Soft Hackle Sulphur	14-18	Good when fish flash below emergers without showing noses
Nymph	Tan Caddis Pupa	16-18	Useful before the evening surface window

Tactics

Start with soft bank seams, shaded flats, and riffle tailouts where the cold release gives fish both cover and oxygen. Nymphs, wet flies, or a dry-dropper are the better search tools until you see repeatable rises. Once fish commit to a lane, simplify to one dry or a dry with an emerger and lengthen the leader before changing patterns too quickly. If thunderheads build, quit early rather than waiting for the first close strike. Keep checking temperatures if you leave the West Branch; the cold reading here does not make the rest of the system safe.
