Upper Delaware, New York
West Branch Delaware Fishing Report: July 29, 2026
The West Branch came through last night's rain in fishable shape around Hale Eddy, while nearby freestones are flooding and more showers keep safety in play.
- Status
- good
- Flow trend
- falling
- Best window
- Midday sulphurs near Deposit, with radar and gauges open all day
- Best methods
- dry flies, wet flies, nymphs, streamers
Quick Summary
The West Branch is the fishable New York trout option in this morning's set, but it sits inside a flood-watch day and should be treated with care. USGS showed 679 cfs, 3.10 feet, and 50.2 F at Hale Eddy during the 8 AM check, with the gauge already easing after the overnight bump. Local Delaware-system context reported a 500 cfs Cannonsville release, clear enough water on the West Branch, and much harder flooding on the Beaverkill and parts of the East Branch. Fish the upper West Branch sulphur and olive window near Deposit if conditions stay stable; keep radar and gauges open, avoid long commitments, and leave if thunder, dirty feeders, or a fresh rise develops.
Conditions Snapshot
| Field | Value |
|---|---|
| Status | Good, with flood-watch caution. The Hale Eddy reading is cold and fishable, but surrounding rivers are high and additional showers or thunderstorms could change the river quickly |
| Flow | 679 cfs at Hale Eddy during the 8 AM USGS check |
| Gauge Height | 3.10 feet at Hale Eddy |
| Water Temp | 50.2 F at Hale Eddy |
| Clarity | Not reported by official gauges; current Delaware public source context reported the West Branch clear enough to fish after the storms |
| Trend | Falling after an overnight storm bump at Hale Eddy |
| Best Window | Midday sulphurs near Deposit before or between showers; evening only if the river is stable and lightning risk is gone |
| Best Method | Dry flies and emergers during sulphur and olive activity; soft hackles or nymphs in cleaner lower-river seams; streamers only if rain adds safe, fishable stain |
| Wadeability | Limited. Known soft edges may fish, but boats are easier and long crossings are a bad plan during a flood watch |
Weather
For Hancock and Hale Eddy, the National Weather Service forecast issued around the morning check calls for a high near 76 F with northwest wind around 6 mph. Showers and thunderstorms become more likely through the afternoon, with showers and thunderstorms likely again tonight. A Flood Watch remains the main weather constraint for the Delaware and Sullivan County area through this evening, so the safest approach is to fish near an exit and keep checking both radar and the Hale Eddy gauge.
River Notes
The West Branch was spared the worst of last night's runoff compared with the Beaverkill and other Delaware tributaries. A cold 50 F tailwater reading and a workable Hale Eddy flow give anglers a real opportunity, especially in the Deposit reach where the release keeps temperatures steady and daytime sulphurs remain the main event. The tradeoff is situational safety: feeder creeks can carry color, nearby rivers are already flooding, and another thunderstorm cell could turn a manageable float or wade into a poor decision. Keep the first pass on the upper West Branch, watch water color at tributary mouths, and do not assume the lower system is in the same shape as the Hale Eddy gauge.
Hatch Activity
Official gauges do not report hatches. Current Delaware-system reports and late-July tailwater timing support sulphurs, small olives, Isonychias, tan caddis, Light Cahills, spinners, and a few terrestrials. The upper West Branch remains a small-fly, dry-and-emerger game when fish are showing; algae still makes heavy upper-river nymphing less attractive than clean surface or near-surface presentations.
| Hatch | Size | Notes |
|---|---|---|
| Sulphur | 16-20 | Main Deposit-area hatch; carry duns, emergers, cripples, and soft hackles |
| Blue Winged Olive | 16-24 | Small olives can mix with sulphurs under clouds or light rain |
| Isonychia | 10-14 | Useful as a larger searching dry, wet fly, or nymph around riffles and edges |
| Tan Caddis | 16-20 | Pupa, soft hackles, and adults cover broken water between mayfly pushes |
| Light Cahill | 14 | Pale mayfly option for evening broken water if storms clear |
| Rusty and Sulphur Spinners | 16-24 | Carry for last light, but skip the spinner fall if thunder or a fresh rise is nearby |
| Ants and Beetles | 14-20 | Bank-side backup during quiet periods, especially if fish are not locked on mayflies |
Recommended Flies
| Category | Fly | Size | Notes |
|---|---|---|---|
| Dry | Sulphur Sparkle Dun, Comparadun, or CDC Emerger | 16-20 | Primary match for upper West Branch risers |
| Dry | BWO Comparadun or CDC Dun | 16-24 | Use when fish key on smaller olives mixed into the sulphurs |
| Dry | Isonychia Parachute or Comparadun | 10-14 | Larger profile for riffle edges and searching water |
| Dry | Elk Hair Caddis or X-Caddis | 16-20 | Small tan caddis option for riffles, seams, and prospecting |
| Dry | Light Cahill or Pale Evening Dun | 14 | Evening option only if storms clear and the river is stable |
| Dry | Rusty Spinner or Sulphur Spinner | 16-24 | Keep ready for last light, but do not stay on the water through thunder |
| Dry | Ant or Beetle | 14-20 | Bank-side summer backup during pauses in hatch activity |
| Wet | Soft Hackle Sulphur or Soft Hackle Pheasant Tail | 14-18 | Swing through riffle tails during emergences |
| Nymph | Pheasant Tail, Frenchie, or Split-Back Mayfly | 14-18 | Better in cleaner lower-river seams; check the fly often for algae |
| Nymph | Isonychia Nymph | 10-12 | Good larger subsurface choice near riffle edges |
| Streamer | Woolly Bugger, Sculpin, or Zonker | 4-8 | Carry for safe stained-water edges after showers, not for fishing through lightning or a fast rise |
Tactics
Start by reading the river, not just the calendar. If sulphurs or olives are moving in the upper river, fish one accurate dry or a dry with a small emerger dropper and keep the leader long enough for flat tailwater fish. If the surface is quiet, swing soft hackles before dropping into a sparse nymph rig, and avoid upper-river algae mats. If a shower adds a little color without a dangerous rise, work a modest streamer tight to softer banks and structure. Stay conservative around 680 cfs, skip long crossings, and leave immediately if thunder is close, feeder creeks turn dirty, or the Hale Eddy gauge starts climbing again.
