The West Branch of the Delaware is the water most Eastern anglers measure everything else against. It runs about 17 miles from Cannonsville Dam at Stilesville down to Junction Pool at Hancock, where it joins the East Branch to form the main-stem Delaware, and its cold comes straight off the bottom of Cannonsville Reservoir — a New York City water-supply impoundment. That bottom release is the whole fishery: through the dog days of a Catskills summer, when nearly every freestone in the region pushes into the 70s and shuts down, the West Branch below the dam can sit in the low 50s. Flows here are set by reservoir releases and interstate water rules under the Flexible Flow Management Program, not by the weather, so the river fishes cold and technical all summer long.

The trout are wild — browns first, with a strong contingent of wild rainbows — and decades of pressure on flat, gin-clear water have made them expert refusers. This is technical dry-fly water above all else: fish rise selectively, often to the smallest bug on the water, and leaders run 12 to 15 feet down to 5X and 6X. How the river fishes depends entirely on what's coming out of the dam. Around 375-475 CFS at Hale Eddy it's almost fully wadeable; at 600-800 CFS a drift boat becomes the better tool with 60-70% still wadeable; north of 1,500 CFS it's too big and pushy to wade safely. A low, warm-release year concentrates fish and anglers in the top few miles near Stilesville where the water stays coldest, while a cold, generous release spreads them the whole way to Hancock.

The hatches are the draw: Hendricksons in April, an extended sulphur season from May into September, Green Drakes in late May and June, blizzard Trico spinner falls in late summer, and Isonychia into fall. It gets crowded — this is a destination fishery within three hours of New York City, and a prime hatch evening on the Hale Eddy flats can feel like a parade of drift boats. Down low the river swings onto the NY-PA state line and becomes boundary water. Full-service fly shops, lodges, and Orvis-endorsed guides cluster around Deposit and Hancock, and their daily reports are genuinely useful for reading the release schedule before you commit to the drive.

Species

  • Brown Trout
    Primary · May-Jun, Sep-Oct · 10-20"+

    The signature fish and the dominant species — wild, self-sustaining, and famously selective on the flats. Fish to 20"+ are realistic. They will inspect a size-18 sulphur, drift with it, and refuse it, so long fine leaders and a drag-free presentation matter more than the pattern. Best on dries during hatches; streamers move the biggest pre-spawn browns in the fall.

  • Rainbow Trout
    Common · May-Jul · 10-17"

    A strong wild population, thickest in the cold upper reaches below the dam. Hard-fighting and often holding in the faster riffle water where they'll take an Isonychia or sulphur emerger more willingly than the pool-tail browns.

  • Brook Trout
    Occasional · Spring, fall · 6-10"

    Present but uncommon in the mainstem — more a tributary and headwater fish that drops in from cold feeder creeks. A wild brook trout here is a nice incidental, not a target.

  • American Shad
    Occasional · May-Jun · 3-6 lb

    Anadromous shad run up the main stem and nose into the lowest West Branch near Hancock in late spring. Incidental to trout fishing, but a fun heavy-rod diversion during the run.

  • Striped Bass
    Occasional · Spring · varies

    Occasional stray in the lowest reaches near the confluence during the spring run. Not a West Branch trout-fishing target.

Ideal wading flow375–475 CFS
Blow-out>1,500 CFS
Ideal water temp50–62°F

Late May-June is the marquee window — the peak convergence of sulphurs, Green Drakes, and cool flows. September-October is the second act: Isonychia and BWOs, cooler water, streamer season for pre-spawn browns, and thinner crowds. July-August stays alive on Trico mornings and cold releases when other rivers cook, but it's low, clear, and technical. April opens with Hendricksons and Quill Gordons. As a bottom-release tailwater, warmth is rarely a concern near the dam; in a low-release summer the cold concentrates in the top few miles below Stilesville, while the lower river toward Hancock can warm as the release dissipates — watch water temp down low in a dry year.

Sections

3 sections on this river

Stilesville — Cannonsville Dam to Deposit

WadeBrown Trout · Rainbow Trout

The coldest water on the river, straight off the bottom of Cannonsville Reservoir — riffle-and-pool with faster pocket water up top. The USGS gauge at Stilesville sits just below the dam, and in a low, warm-release summer this is where the wild brown trout and rainbow trout, and the anglers, concentrate because it stays coldest. The Route 17 bridge at Deposit is the downstream boundary of the year-round no-kill section.

Best for: Wild brown trout and rainbow trout on dries during hatches; nymphing and streamers when nothing is rising. The cold bottom release keeps this reach fishable through mid-summer heat.

Deposit to Hale Eddy

Wade & FloatBrown Trout · Rainbow Trout

Classic Delaware flat-and-riffle water — long glassy pools separated by riffles, the reach that made the river's dry-fly reputation. The Hale Eddy gauge at the bottom is the flow number every fishing report quotes. This is where the pickiest wild brown trout live, and where sulphur, BWO, and Trico hatches bring them up in numbers.

Best for: Selective sight-fishing to rising brown trout and rainbow trout during hatches — long leaders, fine tippet, and small flies. Very wadeable near 375-475 CFS and drift-boat friendly as releases climb.

Hale Eddy to Junction Pool

FloatBrown Trout · Rainbow Trout

The river swings toward the NY-PA state line and grows in volume, holding some of the most productive water on the system as it approaches Hancock. Balls Eddy and Shehawken (both PA) are the major launches; Junction Pool at Hancock is where the West and East Branches meet to form the main-stem Delaware. Bigger holding water for larger wild brown trout, best covered by boat.

Best for: Floating anglers covering water for wild brown trout and rainbow trout; strong hatches, larger holding lies, and streamer fishing in spring and fall. Best fished from a drift boat at higher releases; wadeable in spots at low flow.

Regulations

Current fishing rules and restrictions

New York manages the West Branch under a special catch-and-release, artificial-lures-only section immediately below Cannonsville Dam, with the rest of the river governed by NY-PA border-water rules (the lower reach forms the state line). A New York fishing license covers the PA-side portion of the boundary water. Verify current rules before fishing.

  • Special section (Cannonsville Dam downstream to the Route 17 / I-86 bridge at Deposit): catch-and-release only, artificial lures only, year-round
  • Border-waters trout (rest of the river / NY-PA boundary reach): open season April 1 - October 15, any method, daily limit 1 trout, no minimum length
  • Border-waters trout, October 16 - March 31: catch-and-release, artificial lures only
  • New York State fishing license required (age 16+); a NY license covers the out-of-state PA-side portion of the boundary water under the reciprocal NY/PA agreement
  • The special-regulation reach is not stocked — the fishery is wild and self-sustaining

Because the lower river is NY-PA boundary water, the DEC border-waters table also sets limits for other species (smallmouth bass, walleye, muskellunge, striped bass) that differ from inland NY rules. Regulations reflect the 2026 season; confirm the special-section boundaries and border-water limits annually.

Access & Logistics

Getting there, fly shops, and lodging

Getting There

Deposit, NY

~2.5-3 hrs from New York City; ~3 hrs from Albany; ~3 hrs from Philadelphia; ~40 min from Binghamton (BGM)

Fly Shops

Camping & Lodging

Streamside resorts anchor the corridor — West Branch Angler Resort (cabins, restaurant, on-site fly shop and guides near Hancock) and The Delaware River Club (lodging, fly shop, and school on the PA side near the border). The Troutfitter Inn sits right in Deposit at the top of the river. Bear Spring Mountain state campground and various private campgrounds fill in the Hancock-Deposit corridor.

Access is a mix of NY and PA marked pull-offs — Deposit and Hale Eddy on the NY side, Balls Eddy and Shehawken on the PA side — plus a lot of good water reachable only by boat. Deposit (Broome County) is the closest town to the Stilesville/upper reach and the dam; Hancock (Delaware County) sits at Junction Pool and is the hub for the lower river. Expect crowds on prime hatch evenings, especially on the Hale Eddy flats. Reading the daily reservoir-release schedule before you drive is the single most useful piece of planning here.

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.

East Branch Delaware RiverNY

The Catskills' quieter tailwater — cold releases from Pepacton Reservoir hold the upper river in the 50s through summer, growing wild, selective browns on long flat pools when the freestones nearby run too warm. Below the Beaverkill it doubles in size, warms, and turns to drift-boat water with more rainbows down to Hancock.

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.

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.
