Upper Delaware, New York
West Branch Delaware Fishing Report: August 4, 2026
The West Branch has dropped back to a better fishing level at Hale Eddy with cold water, good reported clarity, and a usable mix of sulphur dries, olives, wets, and nymphs.
- Status
- good
- Flow trend
- falling
- Best window
- Midday sulphur window in Deposit, then late afternoon into evening if the water stays clear
- Best methods
- dry flies, nymphs, wet flies
Quick Summary
The West Branch is in better shape this morning than it was after yesterday's rain. USGS showed 804 cfs, 3.33 feet, and 51.8 F at Hale Eddy during the 8 AM report check, down from the prior morning and still comfortably cold for trout. Current Upper Delaware source context reported good clarity, a 500 cfs Cannonsville release, summer sulphurs on the upper West Branch around midday, and algae on the upper river that can make subsurface rigs frustrating. Treat this as a good fishing day, with careful wading, dries and wets up top, and nymphing focused more on the lower West where algae is less limiting.
Conditions Snapshot
| Field | Value |
|---|---|
| Status | Good. The river is cold, falling, and reported clear enough to fish, though wading still requires care |
| Flow | 804 cfs at Hale Eddy during the 8 AM report check |
| Gauge Height | 3.33 feet at Hale Eddy |
| Water Temp | 51.8 F at Hale Eddy |
| Clarity | Reported good on the West Branch this morning; official gauges do not measure clarity |
| Trend | Falling over the prior 24 hours |
| Best Window | Midday sulphurs in the Deposit reach, then late afternoon into evening if cloud cover or low light helps fish look up |
| Best Method | Dry flies and wets on the upper river; nymphs or a dry-dropper on the lower West |
| Wadeability | Limited to fair depending on access. Use softer margins and skip heavy mid-river pushes |
Weather
For Hancock and Hale Eddy, the National Weather Service forecast calls for fog early, then sunny weather with a high near 83 F and almost no wind. That is comfortable for casting but bright for trout. Plan around shade, broken water, and the known midday sulphur window rather than expecting all-day surface feeding. No meaningful rain is in the daytime forecast, so the main safety issue is pushy post-rain water rather than lightning or new runoff.
River Notes
The 24-hour trend is the important change: Hale Eddy fell from roughly the low 1,300s yesterday morning to 804 cfs during this check. That puts the river back into a much more usable range for drift boats and selective wading, with enough current to keep trout comfortable in the main seams. Fish the upper tailwater if you want the coldest water and a dry-fly shot, but be ready for algae that can foul nymph rigs. If you need to fish subsurface, the lower West should be the better starting point. Clarity was reported improved this morning, but anglers should still watch for isolated stain or debris after yesterday's runoff.
Hatch Activity
Official gauges do not report hatches. Current Upper Delaware source context supports summer sulphurs around midday in Deposit, small Blue Winged Olives, scattered Isonychias, Cahills, tan caddis, and spinners. Bright sun may shorten the dry-fly window, so keep wets, emergers, and a dry-dropper ready when fish are not rising steadily.
| Hatch | Size | Notes |
|---|---|---|
| Sulphur | 16-20 | Best reported midday hatch on the upper West Branch; carry duns, emergers, and cripples |
| Blue Winged Olive | 18-24 | Small olives are mixed in; more important during shade, haze, or low-light edges |
| Isonychia | 10-14 | Scattered larger mayfly and a useful nymph or wet-fly profile in faster water |
| Tan Caddis | 16-20 | Pupa and soft hackles can cover broken riffles when surface activity is weak |
| Light Cahill | 14-16 | Carry for evening or softer light windows |
| Rusty and Sulphur Spinners | 16-24 | Worth having at last light if the water stays calm enough for flat-water risers |
| Ants and Beetles | 14-20 | Useful along grassy banks during bright summer weather |
Recommended Flies
| Category | Fly | Size | Notes |
|---|---|---|---|
| Dry | Sulphur Sparkle Dun, Comparadun, or CDC Emerger | 16-20 | First box to open during the Deposit sulphur window |
| Dry | BWO Comparadun or CDC Dun | 18-24 | Match the smaller olives mixed into the sulphurs |
| Dry | Light Cahill or Isonychia Parachute | 10-16 | Prospecting option along riffle edges and softer bank seams |
| Dry | Ant or Beetle | 14-20 | Good summer backup under grassy banks and overhanging cover |
| Nymph | Pheasant Tail, Frenchie, or Perdigon | 14-18 | Use on the lower West where algae is less likely to ruin every drift |
| Nymph | Isonychia Nymph | 10-12 | Good searching fly in faster seams and riffle drops |
| Wet | Soft Hackle Sulphur or Soft Hackle Pheasant Tail | 14-18 | Swing just under the film when bugs are present but rises are scattered |
| Streamer | Small Sculpin or Woolly Bugger | 6-10 | Backup if you find leftover stain or bank-oriented fish |
Tactics
Start on the upper West if your goal is dry-fly fishing during the sulphur hatch. Use a longer leader, watch one lane at a time, and switch between dun, emerger, and cripple profiles before changing size too far. If algae makes nymphing impractical above Oquaga Creek, move downriver and work nymphs or wets through walking-speed seams and inside bends. Wading is improved but not casual at 804 cfs; avoid heavy mid-channel crossings and fish from stable margins.
