The East Branch is the Catskills' other tailwater — the one that lives in the West Branch's shadow, and is better for it. Below Pepacton Reservoir at Downsville, the reservoir's cold bottom releases hold water temperatures in the 50s well into a Catskill summer, so the upper river fishes for wild, stream-bred browns when the freestone Beaverkill and Willowemoc a valley over are pushing 70F and shutting down. The releases are smaller and less reliable than the Cannonsville flows that feed the West Branch, so the East Branch runs skinnier and clearer — a river of long flat pools, weedy spring-creek glides, and braided island channels where a wild sixteen-inch brown will refuse a size-18 sulphur that's dragging by an inch. It rewards a good drift and punishes a sloppy one.

The river splits at a personality line where the Beaverkill dumps in near the hamlet of East Branch. Above that, from Downsville down through Shinhopple, it's small, cold, and mostly wadeable — a technical dry-fly and light-nymph fishery for wild brown trout and the occasional brook trout out of the tributaries, best from Downsville down where the releases keep it honest. Below the Beaverkill the river roughly doubles in flow (Fishs Eddy runs 300-plus CFS in summer against about 150 up top), warms, and turns into big drift-boat water with more rainbow trout down to the West Branch junction at Hancock. That lower stretch is superb in spring and fall, but the last few miles can climb past 80F in a July heat wave, which pushes trout upstream toward the cold.

Access is a mix of DEC public fishing rights and pull-offs along Route 30 and Route 17/I-86, private frontage below the Beaverkill, and boat launches centered on Downsville and Hancock. Pressure exists but runs lighter than the West Branch and the famous Beaverkill/Willowemoc — the East Branch is where locals go when the marquee water is crowded. The one number to know before you drive is the Downsville release: when it climbs toward roughly 850 CFS, Pepacton is starting to spill and the upper river goes high and off-color. In a normal summer you're fishing 100-250 CFS up top.

Species

  • Brown Trout
    Primary · Apr-Jun, Sep-Oct · 10-18", some to 20"+

    The defining fish, especially the upper tailwater from Downsville to Shinhopple — wild, stream-bred, and genuinely selective on the flat pools. Holdover stocked fish mix in, but the appeal is the wild browns that sip small mayflies on a dead-drift.

  • Rainbow Trout
    Common · May-Jun, Sep-Oct · 10-16"

    More common in the lower river below the Beaverkill confluence, part of the Upper Delaware system's wild rainbow strain. Strong, acrobatic fish that show best on the drift down toward Hancock.

  • Brook Trout
    Present · May-Jun · 6-10"

    Wild resident brook trout drop in from colder tributaries and the extreme upper reaches — a bonus rather than a target, most likely in cool water high in the system.

  • Smallmouth Bass
    Present · Jun-Sep · 8-14"

    Resident in the warmer lower river near Hancock through the summer months. Incidental for trout anglers but a legitimate warm-water option when the lowest miles heat up.

Ideal wading flow100–300 CFS
Blow-out>854 CFS
Ideal water temp50–65°F

Two prime windows plus a spring opener. Late May through June is the marquee dry-fly stretch — the Hendrickson tail into sulphurs, March Browns, and the short, famous Green Drake window. September and October bring cooler water, BWO and Isonychia, lighter pressure, and pre-spawn browns. April kicks off with early caddis, Quill Gordons, and the first Hendricksons. Midsummer is a morning-trico, evening-sulphur, and terrestrial game — and in a heat wave, an upper-river-only game, since the cold Downsville tailwater is the system's refuge when the last miles near Hancock climb past 80F.

Upper East Branch — Downsville to Shinhopple / Beaverkill Confluence

WadeBrook Trout · Brown Trout · Rainbow Trout

The cold tailwater below Pepacton Dam — small, clear, and spring-creek in character, with long flat pools, weed beds, and braided channels around islands, plus some pocket water near Downsville. Bottom releases keep it in the 50s all summer, making it the system's cold-water refuge when the freestones are too warm. DEC public fishing rights and pull-offs line Route 30, and most of the reach wades. Home water for wild brown trout and the odd tributary brook trout.

Best for: Wild brown trout on technical dry-fly and light nymphing — fine tippet and careful drifts for selective fish on flat water.

Lower East Branch — Beaverkill Confluence to Hancock

FloatBrown Trout · Rainbow Trout

Below the Beaverkill inflow the river roughly doubles in volume and becomes broad drift-boat water — big pools and riffles running down to the West Branch junction at Hancock, where the two branches form the Main Stem. Wild rainbow trout become more common alongside the browns, and the Fishs Eddy gauge captures the combined East Branch and Beaverkill flow. The lowest miles warm into the 80s in a July heat wave, so trout push upstream toward the cold; spring and fall are the productive windows.

Best for: Wild rainbow trout and brown trout on spring and fall dry-fly and streamer floats.

Regulations

Current fishing rules and restrictions

The East Branch is governed by New York's statewide trout-stream regulations — there is no separate special-regulation reach listed for it in the DEC Region 4 table (that table covers the reservoirs, not the river). Harvest season runs roughly April 1 through mid-to-late fall depending on the reach, with statewide artificial-lure catch-and-release in the closed period. Confirm the current-year category and reach boundaries against the NY Freshwater Fishing Regulations Guide before a trip.

  • Statewide trout-stream limits apply: default 5 trout per day, no more than 2 over 12 inches — confirm the East Branch's assigned category, as some Delaware-system reaches carry stricter artificial-only or reduced-creel designations.
  • Harvest season is widely reported as April 1 through October 15 from Downsville down to Shinhopple, extending to November 30 from Shinhopple to Hancock; statewide artificial-lure catch-and-release applies in the closed period (Oct 16 - Mar 31).
  • New York freshwater fishing license required, age 16+.
  • The East Branch above Hancock is not border water — use NY inland trout-stream regs, not the NY/PA border-water rules that govern the Main Stem and West Branch.

Reach boundaries and the exact season/creel category should be verified against the current NY 2026 Freshwater Fishing Regulations Guide before publishing a trip plan — the statewide 2021 trout-stream overhaul assigns categories per reach.

Access & Logistics

Getting there, fly shops, and lodging

Getting There

Downsville, NY

~2.5-3 hrs NW of New York City; ~1 hr SW of the Albany area. Nearest larger airports are Binghamton (BGM, ~50 min from Hancock) and Albany (ALB, ~1.5 hrs); NYC-metro airports ~3 hrs.

Fly Shops

Camping & Lodging

State and private campgrounds cluster around Downsville and Shinhopple; lodges and cabins concentrate at Hancock and the West Branch Angler resort at Shehawken, with motels in Downsville and nearby Roscoe.

DEC public fishing rights and pull-offs line Route 30 through the upper river and Route 17/I-86 along the lower. The upper reach from Downsville to Shinhopple is largely wadeable; below the Beaverkill much of the bank is private, so a drift boat launched near Fishs Eddy or Hancock is the standard approach. Roscoe ("Trout Town USA," about 20 minutes away) is the regional fly-fishing hub.

Conditions data is live from public monitoring networks. Regulations change annually — always verify current rules with your state fish & wildlife agency before fishing.

Delaware River System

Delaware RiverNY

The "Big D" — the largest wild-trout river in the East, formed where the cold West and East Branch tailwaters meet at Junction Pool in Hancock. Powerful, technical flat-water pools full of stream-bred wild rainbows and browns, a rare Catskill spring shad run, and legendary Hendrickson, sulphur, and green drake hatches. Summer water temperature, not low flow, is the limiting factor.

Neversink RiverNY

The river where American dry-fly fishing was born — Theodore Gordon worked out the first American-tied dries here in the 1890s. Today it's really two rivers split by a dam: a cold, technical no-kill catch-and-release brown-trout tailwater below Neversink Reservoir that stays fishable through August heat, and a warmer wild freestone above the reservoir near Claryville holding brook and brown trout.

West Branch Delaware RiverNY

The East's premier cold dry-fly tailwater, running below Cannonsville Dam to Junction Pool at Hancock. Bottom-release water keeps wild browns and rainbows on flat, gin-clear pools where selective fish and long, fine leaders are the price of admission.

Other regions

Beaverkill RiverNY

The birthplace of American fly fishing — the freestone Theodore Gordon and the Dettes fished, meeting the Willowemoc at Junction Pool in Roscoe, "Trout Town, USA." A wide, classic Catskill river of long riffles and deep pools with the sport's most storied named water (Cairns, Barnhart's, Hendrickson, Horse Brook Run) in the no-kill reaches below Roscoe. Wild and stocked browns throughout, wild brookies up high, on a hatch calendar that runs from Quill Gordons in April through the famous dusk Green Drake spinner fall in late May. A wade river best in spring and fall — the lower reaches warm into the 70s by July, which is why DEC closes the Horton reach July 1-August 31.

Esopus CreekNY

The working-man's Catskill river — a dense wild rainbow fishery that keeps fishing when the Beaverkill and the Delaware branches run the color of chocolate milk, because the Shandaken Portal pipes cold reservoir water into the upper creek and turns the Phoenicia reach into a de-facto tailwater. The flip side: Portal releases and turbid Stony Clove Creek can cloud it up on their own schedule.

Salmon RiverNY

New York's marquee Great Lakes tributary: a short, dam-controlled Lake Ontario river that fills with Chinook and coho salmon every fall and holds fresh steelhead and lake-run brown trout all winter. A run-timing, egg-and-swing fishery from the Altmar hatchery down to the Pulaski town pools and the private Douglaston Salmon Run, with flow set by the Lighthouse Hill hydro dam, not the weather.

West Branch Ausable RiverNY

The most famous trout stream in the Adirondacks: a boulder-strewn freestone of plunge pools and pocket water tumbling past Whiteface Mountain, where Fran Betters tied the Ausable Wulff. Wild browns and brook trout, easy roadside access off Route 86, and two year-round catch-and-release stretches.

Willowemoc CreekNY

One of the two streams the Catskill dry-fly tradition was built on — it meets the Beaver Kill at Junction Pool in Roscoe, "Trout Town USA." A classic medium freestone of tea-stained riffles and pools, mostly stocked browns and rainbows in the lower river with wild brookies up in the small headwaters, best fished during the famous hatch parade from Quill Gordons in April through summer Sulphurs. A wading stream end to end, anchored by a year-round catch-and-release no-kill stretch above Roscoe.
