Catskills, New York
Beaverkill and Willowemoc Creek Fishing Report: June 7, 2026
The Beaverkill and Willowemoc are wadeable after a small bump, but warm Beaverkill water makes this an early-or-late trout-temperature call.
- Status
- fair
- Flow trend
- rising
- Best window
- Early morning and the last hour of light, with strict trout-temperature checks
- Best methods
- dry flies, nymphs, wet flies
Quick Summary
The Beaverkill and Willowemoc are wadeable and fishable in the right windows, but this is only a fair trout report because the Beaverkill remains warm enough to demand restraint. USGS showed the Beaver Kill at Cooks Falls at 229 cfs, 1.79 feet, and 63.9 F at about 7:30-7:45 AM EDT; Willowemoc Creek near Livingston Manor was 50.4 cfs, 2.03 feet, and 57.9 F at about 7:15 AM EDT. Local Catskills context from this morning described the rivers as bumped slightly and in good wading shape, with nymphs, wet flies, dry-droppers, and the best dry-fly work near dark. The safety note matters most: the Beaverkill reached the 70 F range yesterday, so carry a thermometer and stop targeting trout well before the water reaches 68 F.

Weather
For Roscoe, NY, the National Weather Service forecast calls for a high near 75 F with mostly sunny conditions after morning clouds and a slight chance of showers late in the afternoon. Northwest wind should run 7-13 mph. Tonight is forecast to be partly cloudy with a low around 52 F. No active NWS alerts were found for the Roscoe point at report time, but afternoon sun and wind can still push freestone water temperatures into poor trout-fishing territory.
River Notes
The flow bump helps the fishing compared with very low summer-like water, but it does not erase the temperature issue. The Willowemoc is cooler at the morning gauge and is the better first look if you are set on fishing freestone water. The Beaverkill is already in the low 60s in the morning and reached the 70 F range yesterday, so treat Cooks Falls and similar lower, exposed water as a short-window fishery. Fish shaded riffles and pocket water early, then recheck temperatures through the day rather than assuming the morning number will hold.
Hatch Activity
The Catskills remain in an early-June mix of Gray Fox, sulphurs, Isonychia, Blue Winged Olives, Blue Sedge, remaining Green Drakes and Coffin Flies, plus evening rusty and sulphur spinners. Local context points to the best dry-fly fishing close to dark, while daytime periods favor nymphs, wets, and dry-dropper rigs in faster riffles and pocket water. If water temperatures climb, the right move is to stop fishing rather than wait out the hatch over stressed trout.
| Hatch | Size | Notes |
|---|---|---|
| Gray Fox | 12-14 | Good around pool heads, riffles, and broken mayfly activity |
| Invaria Sulphur | 14-16 | Key late-day mayfly; carry emergers, duns, and spinners |
| Isonychia | 10-12 | Nymphs and wets are useful in faster seams before surface feeding steadies |
| Blue Winged Olive | 18-20 | Worth having for shade, cloud cover, and selective fish |
| Blue Sedge | 14-16 | Fish pupa, wets, and adults through riffles and pocket water |
| Green Drake / Coffin Fly | 8-10 | Still possible near dusk, but do not force big bugs over smaller rise forms |
| Rusty or Sulphur Spinner | 10-18 | Most useful near dark if temperatures remain safe |
Recommended Flies
| Category | Fly | Size | Notes |
|---|---|---|---|
| Dry | Gray Fox Comparadun | 12-14 | Visible mayfly for broken water, bank seams, and pool heads |
| Dry | Sulphur Sparkle Dun or Spinner | 14-16 | Use later in the day when lighter mayflies draw steady rises |
| Dry | Green Drake or Coffin Fly | 8-10 | Carry for dusk, but match smaller bugs if fish show smaller rise forms |
| Dry | BWO Comparadun | 18-20 | Use under clouds, in shade, or over small sipping fish |
| Dry | Blue Sedge or Tan Caddis | 14-16 | Search riffle edges and pocket water when caddis are moving |
| Nymph | Isonychia Nymph | 10-12 | Work faster seams and riffle margins during slower surface periods |
| Nymph | Caddis Pupa | 14-16 | Dead drift or swing through riffle tails and pocket water |
| Nymph | Pheasant Tail or Copper John | 14-18 | Good dry-dropper choice for clear pocket water |
| Wet | Partridge and Yellow or Leadwing Coachman | 12-16 | Swing when mayflies or caddis are active but rises are scattered |
| Streamer | Small Olive or Brown Bugger | 6-10 | Only a low-light option if water is cool enough and visibility is good |
Tactics
Start early on shaded riffles, pocket seams, and bank-side lanes. A dry-dropper, caddis pupa, Isonychia nymph, or soft hackle is a better daytime plan than standing over flat, warming water waiting for risers. If fish start rising near dark and the thermometer still says the water is safe, lengthen the leader and match Gray Fox, sulphurs, caddis, olives, drakes, or spinners by rise form. If the Beaverkill pushes toward 68 F, switch waters or stop fishing for trout.
