The Beaverkill sits at 452 cfs with 42.3°F water — excellent late-May conditions with clear, wadeable flows. Water temp is just shy of key hatch thresholds, but BWOs and midges are active during midday warmth. Dette Flies reports black stoneflies, small caddis, and BWOs emerging on warmer afternoons. Focus nymph rigs with small mayfly and caddis patterns as your bread and butter, switching to dries when you spot rises during the 11am-2pm window when air temps climb into the 60s.

- Hatches: BWOs #18-20 and small black caddis emerging midday. Hendricksons winding down, Sulphurs approaching as water warms
- Water Temp: 42.3°F — just below caddis emergence threshold. Watch for 50°F crossing to trigger more consistent surface activity
- Best Window: 11am-2pm when air temps hit 60s. Early mornings productive with nymphs before switching to dry/dropper rigs

About this Water

- Best months: Apr–Oct, peak May–June
The Catskills are the cradle of American fly fishing — the Beaverkill, Willowemoc, and Esopus together form the geographic and historical heart of the sport in the United States. Theodore Gordon, Lee Wulff, and the Dette family all fished and tied here. The Beaverkill below Roscoe (Junction Pool, where the Willowemoc meets it, calls itself 'Trout Town USA') offers classic Eastern dry-fly fishing for wild brown trout and stocked rainbows. The water is technical, the fish educated, and the historical weight palpable. Hendrickson, Sulphur, and Quill Gordon hatches define the season.
Junction Pool in Roscoe — where the Willowemoc joins the Beaverkill — is widely regarded as the most historically significant pool in American fly fishing, featured in Theodore Gordon's 19th-century writings and in countless fly-tying lineages since.
