Upper Delaware, New York
West Branch Delaware Fishing Report: August 14, 2026
The West Branch remains a good August choice, with 749 cfs and 50.7 F water at Hale Eddy, a falling flow, and sulphurs, olives, Cahills, and Isonychias still driving the best dry-fly windows.

Quick Summary
The West Branch is still the strongest New York trout option in this morning's report set. USGS showed 749 cfs, 3.23 feet, and 50.7 F at Hale Eddy during the morning check, with the flow down from yesterday's storm bump and a reported 500 cfs Cannonsville release keeping the river cold. Wading is possible in selected soft-edge spots, but the flow still calls for careful feet and no casual crossings. Expect the best dry-fly chance on the colder upper river around the sulphur and olive activity, with nymphs or wet flies better on the lower West when the surface is quiet.
Conditions Snapshot
| Field | Value |
|---|---|
| Status | Good. The Hale Eddy gauge is cold and fishable for August, and current local context still supports daytime bug activity on the West Branch |
| Flow | 749 cfs at Hale Eddy during the morning check |
| Gauge Height | 3.23 feet at Hale Eddy |
| Water Temp | 50.7 F at Hale Eddy |
| Clarity | Not reported by official gauges; local context does not point to a blown-out river |
| Trend | Falling over the last day at Hale Eddy |
| Best Window | Midday on the colder upper West Branch for sulphurs and olives, with a lower-light evening check if wind stays down |
| Best Method | Dry flies and emergers over working fish; nymphs, wet flies, or a dry-dropper in faster lower-river lanes |
| Wadeability | Limited. Pick bars, banks, and inside seams carefully and avoid unnecessary crossings |
Weather
For Hancock and Hale Eddy, the National Weather Service forecast calls for sunny weather after early fog with a high near 82 F and light northwest wind around 0 to 5 mph. Tonight should be partly cloudy with patchy fog possible and a low near 53 F. The wind forecast is favorable for technical dry-fly work; the main weather constraint is bright sun, so shade lines, softer glare, and the heaviest bug activity should matter.
River Notes
The West Branch is settling into a useful mid-August tailwater range. The morning USGS reading at Hale Eddy was 749 cfs and 50.7 F, down from 826 cfs yesterday morning, so anglers have enough cover and current to move fish without the river being as pushy as it was after the storm bump. The cold release continues to make this water a better trout choice than the warmer Catskill freestones once the day heats up.
Local Upper Delaware context continues to point toward sulphurs as the best daytime dry-fly opportunity, especially on the upper West Branch. Small olives remain mixed in, and Isonychias and summer Cahills are useful searching bugs when fish are less selective. Algae remains a practical issue in parts of the upper river; if a nymph rig is fouling too often, switch to dries, emergers, wet flies, or move to cleaner lower-river lanes.
Hatch Activity
Official gauges do not report hatches. Current Upper Delaware source context supports summer sulphurs, small Blue Winged Olives, Isonychias, Light Cahills, tan caddis, and some terrestrial/spinner opportunity.
| Hatch | Size | Notes |
|---|---|---|
| Sulphur | 16-20 | Primary midday target on the colder upper West Branch |
| Blue Winged Olive | 18-22 | Small olives can mix with the sulphurs and cover subtle riseforms |
| Isonychia | 10-14 | Good searching dry, wet fly, and nymph in broken current |
| Light Cahill | 14-16 | Useful in lower light and as a searching dry when fish are not keyed to sulphurs |
| Tan Caddis | 16-20 | Pupa, soft hackles, and adults are worth carrying around riffles |
| Rusty Spinner and Terrestrials | 12-24 | Keep small spinners, ants, and beetles ready for picky bank or flat-water fish |
Recommended Flies
| Category | Fly | Size | Notes |
|---|---|---|---|
| Dry | Sulphur Sparkle Dun, Comparadun, or CDC Emerger | 16-20 | First box to open when the upper-river sulphurs start |
| Dry | BWO Comparadun or CDC Olive | 18-22 | Match small mixed-in olives and delicate tailwater riseforms |
| Dry | Isonychia Parachute or Light Cahill | 10-16 | Searching option for banks, riffles, and broken seams |
| Dry | Rusty Spinner, Winged Ant, or Beetle | 12-24 | Carry for spinner falls, bank feeders, and selective summer trout |
| Wet | Soft Hackle Sulphur, Soft Hackle Pheasant Tail, or Isonychia Wet | 12-18 | Swing through the film before and during sparse hatch activity |
| Nymph | Pheasant Tail, Perdigon, or Frenchie | 14-18 | Use in cleaner lower-river seams when the surface is quiet |
| Nymph | Isonychia Nymph | 10-12 | Fish faster edges with a controlled swing at the end of the drift |
Tactics
Start with a thermometer and a look at clarity, even on a cold tailwater. If fish are not showing, prospect shaded banks and faster seams with a soft hackle, Isonychia nymph, or compact dry-dropper before committing to a heavy nymph rig. Once bugs appear, lengthen the leader, fish one accurate dry or a dry-and-emerger pair, and make the first drift count. The flow is friendlier than yesterday but still enough to punish careless wading, so stay on softer edges and do not force crossings.
