Live gauge data is unavailable for today, but the most recent web intel (June 20) puts the Beaverkill at 139 cfs and 63.3°F — fishable and wadeable, though water temps will climb toward the stress threshold by midday on a sunny 72°F afternoon. Fish hard early and plan to be off the water by noon.

Best Time Window
- 6 AM - 10 AM: Prime nymphing and BWO dry-fly window in shaded riffles before water temps climb; fish are active and feeding aggressively.
- 10 AM - 12 PM: Terrestrial ant fishing along undercut banks and tree-lined runs; midday lull on hatches but opportunistic fish will take a well-placed ant.
- 6 PM - 8 PM: Evening Sulphur and Cahill hatch in the flats and pool tails; best dry-fly action of the day with spinner falls possible at last light.
Guide's Tip
From the benchWith water temps likely pushing into the upper 60s by midday, concentrate your dry-fly and nymph effort in shaded riffles and the heads of pools during the first three hours of daylight. Come evening, position yourself at the tail of the longer flats by 6 PM and watch for the Sulphur and Cahill spinner falls — fish will stack up in the slick water and sip confidently. Keep your net in the water and releases quick; warm-water fish need every advantage. Monday's heavy rain forecast (1–2 inches) will likely blow the river out, so today is your best shot this weekend.
