Beaverkill in summer low-water mode — terrestrials take center stage

What's biting

What's next

The First Quarter moon on June 23 sets up productive low-light windows at first light and the hour before dark — plan early starts rather than midday sessions. With the Beaverkill holding around 36.5 cfs, fish will be spooky on open runs during bright conditions. Longer leaders (12–15 feet), finer tippets (6X or 7X), and upstream or downstream-reach casts will matter more than usual; classic across-and-swing presentations will put fish down in water this clear.

Terrestrials are the primary daytime story. Ants, beetles, and inchworms become increasingly reliable as June turns the corner — Flylords Mag's recent piece on the Chugger specifically calls it out as a must-tie "for the summer heat," and any foam-backed ant or beetle in size 14–18 is worth carrying. Keep presentations tight to shaded banks and undercut roots where fish hold without committing to open water.

In the evenings, expect whatever hatches remain — sulphurs or caddis, depending on the specific stream — to fire late. Gink and Gasoline's coverage of the trico hatch and spinner fall is worth bookmarking before your next outing: trico activity typically begins in early morning on calmer flats, and late June is when those size 20–22 spinner imitations start earning their keep on the lower Catskills sections.

For the next two to three days, absent a significant rainfall event, flows on both the Beaverkill and East Branch Delaware are likely to hold steady or edge slightly lower. Cold overnight temperatures typical of Catskills elevations in late June may buffer any daytime water temperature spike, but anglers targeting brook trout in the Adirondacks should concentrate on morning windows and spring-fed headwater tributaries where temps stay in the ideal range. If afternoon thunderstorms materialize — common in the region through July — a brief flow bump can produce a short window of active surface feeding as fresh terrestrials get washed in.

Weekend anglers should plan for early access: Trout Unlimited's "True Cast" column acknowledges that summer canoe and tube traffic on Catskills drainages like the West Branch Delaware is a real seasonal factor, and the best fishing on well-known water ends well before the recreational crowds arrive.

Context

At 36.5 cfs, the Beaverkill at Cooks Falls is on the lower end of the typical late-June range for that gauge — not in drought territory, but lean enough to call for cautious wading and a light footprint. The East Branch Delaware at 155 cfs reflects a larger watershed and sits within the normal early-summer envelope for that drainage.

Late June is historically a pivot point for Catskills and Adirondacks trout fishing. The famous spring hatches — Hendricksons, March Browns, Green Drakes — are largely finished by the third week of June. What replaces them is a more exacting game: smaller patterns, delicate presentations, and disciplined attention to shade and water temperature. This is when the Catskills' reputation as a technical dry-fly fishery is fully validated.

Hatch Magazine's piece on fishing through drought conditions captures the wider truth of summer low-water trout angling across the Northeast — even in a normal year, late June means shifting to morning sessions, seeking cold-water refugia, and scaling down to size 20–22 patterns during spinner falls. Those habits apply here regardless of whether 2026 is running wet or dry by historical comparison.

No specific data on how this season is tracking against prior years was available in the current angler intel feeds. Without regional guide or shop reports, it is not possible to characterize whether fish counts or hatch intensity are running ahead of or behind a typical summer. Trout Unlimited continues active restoration work across Catskills and Adirondacks drainages — the cold, clean water these streams depend on is the product of decades of habitat conservation, and the current moderate flows suggest these systems are holding up under early-summer pressure.
