Beaverkill and Willowemoc Fishing Report: June 30, 2026

The Beaverkill is already above the trout-temperature cutoff this morning, and the low Willowemoc leaves little margin, so skip these freestones for trout today.

Status
unsafe
Flow trend
falling
Best window
Skip freestone trout fishing; choose cold tailwater or warmwater alternatives
Best methods
skip warm trout water, cold tailwater alternatives, warmwater options

Quick Summary

Skip the Beaverkill and Willowemoc for trout today. USGS showed the Beaver Kill at Cooks Falls at 118 cfs and 68.7 F during the morning check, which is already above the 68 F trout-stress line before the hottest part of the day. The Willowemoc near Livingston Manor was cooler at 61.0 F but very low at 29.6 cfs, and the Roscoe forecast still calls for a warm, humid day with a chance of afternoon thunderstorms. If you want trout, move to cold tailwater water; if you want to stay local, pick reservoirs, lakes, or other warmwater options.

Conditions Snapshot

FieldValue
StatusUnsafe for trout on the Beaverkill; not recommended on the low Willowemoc because the day will keep warming
Flow118 cfs at Beaver Kill at Cooks Falls; 29.6 cfs at Willowemoc Creek near Livingston Manor
Gauge Height1.22 feet at Cooks Falls; 1.88 feet near Livingston Manor
Water Temp68.7 F at Cooks Falls; 61.0 F near Livingston Manor during the morning USGS check
ClarityNot reported by official gauges; low summer freestone conditions require extra caution even where water looks clear
TrendFlows are low to falling, with water temperature now the main trout-safety constraint
Best WindowNot recommended for trout today
Best MethodSkip freestone trout fishing; use cold tailwater alternatives or warmwater species instead
WadeabilityPhysical wading may be possible in spots, but trout stress makes fishing these freestones the wrong call

Weather

For Roscoe and Livingston Manor, the National Weather Service forecast calls for mostly cloudy conditions with a high near 86 F and a slight chance of showers and thunderstorms between about 2 PM and 3 PM. Southwest wind is forecast at 3 to 9 mph. Tonight has a chance of evening showers and thunderstorms before mostly cloudy conditions and a low near 65 F. The warm forecast means the Beaverkill temperature problem will not improve during the fishing day.

River Notes

The Beaverkill gauge is the deciding fact: 68.7 F in the morning is too warm to justify trout fishing. Even if a shaded bank or spring seep reads cooler, the main river is already past the point where catch-and-release trout pressure is responsible. The Willowemoc reading is cooler, but 29.6 cfs is thin water with limited thermal cushion and little room for fish to recover after a fight. Leave these freestones alone for trout today and check the cold tailwaters instead.

Hatch Activity

Local Catskills context still includes the summer mix of sulphurs, Blue Winged Olives, Isonychias, Light Cahills, caddis, and evening spinners. On the Beaverkill and Willowemoc today, those bugs are not a reason to target trout in warm, low water. Save the hatch box for colder water and carry a stream thermometer for the rest of the week.

HatchSizeNotes
Sulphur16-18Regionally active; fish it only on water that remains safely cold
Blue Winged Olive18-22Clouds may help, but temperature still controls the trout decision
Isonychia10-12Useful nymph or emerger on colder riffle water, not on warm Beaverkill trout today
Light Cahill14-16Evening possibility on alternate cold water
Tan Caddis16-18Pupa and soft hackles remain good searching choices in cold moving water
Rusty Spinner14-20Last-light option only after a thermometer confirms safe temperatures elsewhere

Recommended Flies

CategoryFlySizeNotes
DrySulphur Comparadun or Sparkle Dun16-18Carry for cold tailwater water, not for the warm Beaverkill today
DryBWO Comparadun or CDC Dun18-22Small cloudy-day option only where temperatures stay safe
DryLight Cahill or White Wulff14-16Visible evening fly for alternate cold water
DryRusty Spinner14-20Use only after a fresh temperature check on colder water
NymphIsonychia Nymph10-12Good summer nymph in cold riffles away from stressed freestone trout
NymphPheasant Tail or Frenchie14-18Mayfly nymph for tailwater seams and pocket water that remains cold
NymphCaddis Pupa16-18Work riffles and pocket water on safer alternatives
OtherStream ThermometerNot reportedRequired in this heat; stop targeting trout whenever water approaches 68 F

Tactics

Do not try to build a short trout window on the Beaverkill today. It is already too warm in the morning, and hooking fish in that water puts unnecessary stress on them. If you are in Roscoe, move to a cold tailwater, fish a reservoir edge, or switch to bass, panfish, or another warmwater option. If you check any trout water yourself, take a temperature before fishing and stop immediately if readings approach 68 F. Watch the afternoon radar and get off open water if thunder develops.
