Beaverkill River
The river that invented American dry-fly fishing, and still the best classroom for it.

Matched fly box
| Pattern | Imitates | Size | Technique |
|---|---|---|---|
| Hendrickson Comparadun | Ephemerella subvaria dun | #12-14 | Cast upstream on a 4.5-metre leader; the first heavy rise of the year is usually on this fly. |
| Coffin Fly | Green drake nymph | #10 | A Catskill original; fish it deep and slow before the drake hatch starts. |
| Catskill-style Light Cahill | Stenonema dun | #14 | The classic divided-wing dry; requires a slack-line cast and a long drift. |
| Iso Nymph | Isonychia nymph | #10-12 | Swim it actively in the riffle at dusk; Isonychia nymphs are fast swimmers. |
| Black Nose Dace | Dace | #6 | Streamer for autumn browns in the deeper bends below Cooks Falls. |
The river
The Beaverkill rises in the Catskill highlands and joins the East Branch of the Delaware at Roscoe, and its place in fly-fishing history is out of all proportion to its size. Theodore Gordon fished here; the first American dry-fly patterns were tied for this water. Today it is a small, intimate, brown-trout river with steady hatches in late spring and a serious thermal problem in July and August, when water temperatures climb into the low twenties and the fish should be left alone.
On this river
Casting to Catskill trout
These fish are educated and the water is clear and low. Use a 4.5-metre leader with a 60 cm tippet, make the cast from a position where you never cross a fish with your line, and accept that you will sometimes need to wait twenty minutes for one fish to resume feeding.
The dusk drake
Ephemera guttulata hatches in the last half hour of light in the first two weeks of June. Position yourself before the hatch starts, fish a single #10 dry, and cover rising fish on the near bank first because the light will be gone before you can reach the far side.
Autumn streamers
From late September the browns turn aggressive and the fly can be bigger than anything you used in spring. Fish a #6 streamer across the current on a sinking tip, strip it in 20 cm pulls, and concentrate on log jams and undercut banks — the fish are defending lies rather than feeding.
Licence and rules
When should I come?
The best months are May · Jun · Sep · Oct. May and June for dry flies; mid-September to November for streamers and olives
What licence do I need?
New York requires a fishing licence from 16; a one-day or seven-day nonresident licence is available. The Beaverkill is largely stocked put-and-take water with wild fish in the upper reaches, and there are special regulations on the no-kill stretches near Roscoe. Do not fish when the water temperature is above about 20°C — the catch-and-release mortality in warm water here is high enough to be a real problem.
How does the water behave?
The Beaverkill has no dam, so it lives and dies by rain. Spring flows are good; by mid-July the river is often down to 150 cfs and above 22°C in the afternoons, at which point the correct decision is to go and fish the Delaware tailwater instead. A heavy June thunderstorm will bring it up and cool it for two or three days — those are the days to be there.
