Quick Summary
The West Branch is near 743 cfs at Hale Eddy and 649 cfs at Stilesville after another substantial release increase. The Cannonsville release is reported at 616 cfs. Cold, green-tinted water and added depth support nymphing and streamer fishing before a possible late olive window. Wade conservatively because familiar crossings have changed since Tuesday morning.
Conditions Snapshot
| Field | Value |
|---|---|
| Status | Good. Cold water and useful depth provide several options, though the rising release limits crossings |
| Flow | 743 cfs at Hale Eddy; 649 cfs at Stilesville |
| Gauge Height | 3.22 feet at Hale Eddy; 8.23 feet at Stilesville |
| Water Temp | 49.8 F at Hale Eddy; 52.3 F at Stilesville |
| Clarity | Green tint associated with the reservoir turning |
| Trend | Rising sharply as the larger reservoir release moves downstream |
| Best Window | Late afternoon into evening |
| Best Method | Nymphs and streamers before the hatch; dries for established late-day rises |
| Wadeability | Limited. Stay near known banks and avoid crossings that were comfortable at Tuesday's lower flow |
Weather
The National Weather Service forecast for Hancock calls for sun and a high near 66 F. South wind should remain manageable at 3 to 8 mph. Tonight should turn partly cloudy with a low near 48 F. No active NWS alert covered the forecast point at the 9 a.m. check.
River Notes
Hale Eddy has climbed from about 561 cfs Tuesday morning to 743 cfs, while Stilesville rose from 491 to 649 cfs. A current regional report puts the Cannonsville release at 616 cfs and ties the increase to the Montague flow target. The increase supplies useful fall depth, but anglers should treat the river as changed water and check each crossing from the bank.
Wednesday's regional update favors nymphs early and dry flies later, with small olives providing most of the surface activity. The larger release may move loose algae through the upper river, while lower sections should offer cleaner nymph drifts. The green reservoir tint does not rule out fishing and may favor streamers. Isonychias, Light Cahills, and small hebe mayflies round out the hatch list, but wait for repeat rises before changing from the subsurface program.
Hatch Activity
| Hatch | Size | Notes |
|---|---|---|
| Blue Winged Olive | 16-20 | The main reported late-day hatch; focus on soft seams and pool tails |
| Hebe | 18-20 | Small olive sulphurs are part of the current mayfly mix |
| Isonychia | 12-14 | Nymphs and wets can search riffles and broken water before surface activity |
| Light Cahill | 14-16 | A scattered larger mayfly that can serve as a searching dry |
| Rusty spinner | 12-18 | Carry for isolated late-day spinner activity |
| Caddis | 16-20 | Pupa remain useful in riffles and pocket water |
Recommended Flies
| Category | Fly | Size | Notes |
|---|---|---|---|
| Nymph | Isonychia Nymph, Pheasant Tail, or Frenchie | 12-20 | Drift pool heads, riffle edges, and deeper seams before the surface window |
| Nymph | Caddis Pupa | 16-20 | Work riffles and pockets with a controlled drift |
| Wet | Isonychia Wet or soft hackle | 12-18 | Let the fly swing toward shore at the end of the drift |
| Dry | BWO Comparadun or CDC Olive | 18-22 | Use a long leader after finding a fish that rises repeatedly |
| Dry | Light Cahill or Rusty Spinner | 12-18 | Match larger mayflies or spent adults only when they appear |
| Streamer | Woolly Bugger or slim sculpin | 6-10 | Cover shaded banks and deeper seams early |
Tactics
Start with a compact nymph rig through pool heads and riffle margins, or work a small streamer beside shaded structure. Use enough weight for the new depth without dragging the bottom. Late in the day, watch soft seams and pool tails for olives. Change to a single dry only after a fish establishes a steady rhythm. Avoid blind crossings while the release continues to move through the system.
