Quick Summary

The Beaverkill-Willowemoc system is still a good Catskills choice this morning, with a fresher May 30 local Catskill report now available for hatch context. USGS showed the Beaver Kill at Cooks Falls at 308 cfs, 2.10 feet, and 54.3 F at 7:30 to 7:45 AM EDT, while Willowemoc Creek near Livingston Manor was 73.5 cfs, 2.16 feet, and 51.6 F at 7:15 AM EDT. The current local report describes the rivers as in good shape after cool nights, with sulphurs, Gray Fox, Isonychia, a few Green Drakes and Coffin Flies, olives, and tan or gray caddis available from late afternoon into evening. Flows are falling and wadeable; the main challenge today is north wind, so fish protected banks and riffles first.

Weather

For Livingston Manor and Roscoe, NY, the National Weather Service forecast calls for a high near 60 F with partly sunny skies. North wind is forecast at 12 to 18 mph with gusts as high as 33 mph, which can make the open pools and longer dry-fly casts difficult. Tonight should be mostly clear with a low near 38 F. There were no active NWS alerts for the checked point at report time.

River Notes

The Beaverkill is lower than yesterday but still has enough water to cover fish in classic riffles, pocket water, and deeper runs. The Willowemoc is getting clearer and more technical at 73.5 cfs, so approach slowly, keep false casting down, and avoid stepping into soft edge lanes before fishing them. Morning temperatures are safe for trout on both gauges. A cool, windy forecast lowers the immediate warm-water concern, but freestones can still warm unevenly in shallow afternoon water; use a thermometer if you fish late.

Hatch Activity

The newer May 30 Catskill source check keeps the hatch program current: expect a varied late-May box rather than a single-bug day. Sulphurs, Gray Fox, Isonychia, olives, caddis, and some Green Drake/Coffin Fly activity are all possible from late afternoon into evening. Wind may reduce visible surface feeding during the middle of the day, but nymphs and wets can keep you in the game until the river settles.

HatchSizeNotes
Sulphur14-16Important late-day mayfly on softer currents
Gray Fox12-14Good visible mayfly for riffles, tailouts, and evening lanes
Isonychia10-12Nymphs and wets are useful in faster water before obvious dry-fly activity
Tan / Gray Caddis14-18Fish pupa, soft hackles, and adults through riffles and evening edges
Blue Winged Olive18-22Useful if clouds build or you find quiet fish on smaller bugs
Green Drake / Coffin Fly8-10Carry for low light and heavier rise forms; activity is present but not the whole plan
Rusty Spinner10-20Key evening option if wind relaxes over flat water

Tactics

On the Beaverkill, start with larger nymphs, wet flies, or a visible dry-dropper in riffles and pocket water until trout show consistent rise forms. On the Willowemoc, lengthen leaders, stay low, and fish upstream edge water before walking through it. If gusts make precise dry-fly work impractical, swing wets across riffle tails or tight-line nymph the faster seams. Save spinner, Green Drake, and Coffin Fly work for calmer evening water, and keep checking trout temperatures if you fish shallow freestone sections late.
