Beaverkill-Willowemoc Fishing Report: July 8, 2026
The Beaverkill and Willowemoc are falling into good wading shape, but current local temperature context puts the Beaverkill in trout-stress territory, so rest the freestones and fish cold tailwater instead.

Quick Summary
The Beaverkill and Willowemoc are easier to wade than they were after recent rain, but the 9 AM refresh moves this report from marginal to a rest-the-freestones call for trout. USGS showed the Beaver Kill at Cooks Falls at 366 cfs and 64.0 F, and Willowemoc Creek near Livingston Manor at 67.7 cfs and 61.5 F during the official check; current local Catskills reporting also put the Beaverkill around 70 F by 8 AM. With sun and an afternoon high near 81 F in Roscoe, these streams can warm farther. Skip trout fishing on the freestones today and fish cold tailwater such as the West Branch Delaware instead.
Conditions Snapshot
| Field | Value |
|---|---|
| Status | Unsafe for trout on the freestones today because local temperature context has the Beaverkill in trout-stress territory |
| Flow | 366 cfs at Cooks Falls on the Beaver Kill; 67.7 cfs near Livingston Manor on the Willowemoc |
| Gauge Height | 2.29 feet at Cooks Falls; 2.13 feet near Livingston Manor |
| Water Temp | 64.0 F on the Beaver Kill and 61.5 F on the Willowemoc at the USGS gauges; local reporting put the Beaverkill around 70 F by 8 AM |
| Clarity | Not reported by official gauges; current local reporting treats the freestones as summer-mode water |
| Trend | Falling over the last 24 hours on both gauges |
| Best Window | Skip trout fishing on the freestones today; fish cold tailwater instead |
| Best Method | Thermometer-first decision making, with the practical trout option shifted to cold tailwater |
| Wadeability | Good from a footing standpoint, but temperature makes trout fishing a poor choice |
Weather
For Roscoe, the National Weather Service forecast calls for early fog, then sun with a high near 81 F and light southwest wind. Tonight should be partly cloudy with fog returning and a low near 60 F. No active NWS alerts were posted at the morning check. Thursday brings another warm day with a chance of scattered showers and thunderstorms, so today's falling flows may not stay unchanged if storms hit the basin.
River Notes
The freestones have dropped into more manageable flows, but the main issue is trout stress, not footing. The official gauges still showed cooler water at their measurement points, while current local reporting put the Beaverkill around 70 F by 8 AM. That is enough of a conflict to make the conservative call: do not target trout on the Beaverkill or Willowemoc today unless you personally verify safe temperatures well below 68 F, and even then keep it brief. For a full day of trout fishing, move to colder tailwater.
Hatch Activity
Local Catskills context remains in summer mode: sulphurs, olives, Cahills, Isonychias, tan caddis, Yellow Sallies, Yellow Drakes, and spinners are the relevant box inventory, but water temperature overrides hatch matching on the freestones today. Save the trout box for colder tailwater. Do not grind through warming pools just because the flows are wadable.
| Hatch | Size | Notes |
|---|---|---|
| Blue Winged Olive | 18-22 | Relevant on cold tailwater or genuinely cool shaded water; do not chase them in warm freestone pools |
| Sulphur | 16-18 | Expect better daytime activity on cold tailwaters |
| Light Cahill | 14-16 | Carry for cold-water alternatives rather than forcing freestone trout fishing |
| Isonychia | 10-12 | A good tailwater searching bug when there is no organized hatch |
| Tan Caddis | 16-18 | Pupa and soft hackles can be useful where water remains cold enough |
| Yellow Sally and Yellow Drake | 8-16 | Carry a few for mixed summer surface activity on cold water |
| Rusty Spinner | 14-20 | Evening freestone use is not recommended unless temperatures are safely below 68 F |
Recommended Flies
| Category | Fly | Size | Notes |
|---|---|---|---|
| Dry | BWO Comparadun or CDC Dun | 18-22 | Use on cold tailwater or verified cool water only |
| Dry | Sulphur Comparadun or Sparkle Dun | 16-18 | Better on cold tailwater today |
| Dry | Light Cahill or Parachute Adams | 14-16 | Visible searching dry for colder alternatives, not warm freestone pools |
| Dry | Isonychia Parachute | 10-12 | Prospecting fly where temperatures are safe |
| Dry | Rusty Spinner | 14-20 | Only if evening water is verified safely below 68 F |
| Nymph | Pheasant Tail or Frenchie | 14-18 | For cold-water alternatives or verified safe water |
| Nymph | Isonychia Nymph | 10-12 | Use on cold tailwater riffle edges and seams |
| Wet | Soft Hackle Pheasant Tail or Partridge and Yellow | 14-18 | Useful where trout water is cold enough to fish responsibly |
| Nymph | Tan Caddis Pupa | 16-18 | Dropper option for colder water |
Tactics
Treat the thermometer as the first piece of tackle. With current local reporting already putting the Beaverkill around 70 F this morning, the cleanest plan is to leave these freestones alone for trout and move to cold tailwater or another species. If you check a small, shaded tributary or spring-influenced reach, fish only if it is safely below 68 F, keep any session short, avoid photos and long fights, and stop as soon as temperatures climb.
