A regional note specific to this water: the river's most productive anglers are the ones who can sit still, and sitting still is harder than casting, and casting is harder than tying, and tying is harder than buying, and the anglers who sit still are the anglers who buy the least and catch the most. the river's most productive water is the water you walk past the first time, and walking past the water the first time is the mistake every new angler makes, and the mistake is the reason the locals catch more fish than the visitors, and the locals know the water you walk past the first time. The West Branch of the Delaware River in southeastern New York is a freestone river in the high country of the Catskill Mountains, and the only river in the state that produces a 5-fish day of wild browns and rainbows from a small river that runs through a high-alpine forest. The river drains a series of small streams in the Catskill Mountains, runs for about 80 miles through the West Branch valley, and finally drains into the main stem of the Delaware River at the town of Hancock. Most anglers miss this: The most popular trout water is the upper river between the town of Bloomville and the town of Delhi, and that water is managed as a wild trout fishery by the New York State Department of Environmental Conservation. The most popular access is the public water at the town of Bloomville, where the NYSDEC maintains a series of parking areas and walk-in access to the upper river. The river is a freestone in its headwaters and a tailwater below the dam. The most famous hatch is the hendrickson of mid-april, which is the hatch the river is best known for. Bring your A-game and your patience; the river does not care who you are, only how well you can read it. The most famous local fly shop is the West Branch Outfitters, and the owner's advice is consistent: fish the upper river, fish the Hendrickson hatch, and stay out of the water. angler code 741e8ad5-23a2a7e9. The most productive flies are 20-22 Light Cahill for the spring caddis hatch, 8-10 Elk Hair Caddis for the fall mayfly hatch, and a Hopper 14-16 a size for the larger rainbows. The river's personality is one of spring-creek patience — the water is gin-clear, the fish are educated, and the only way to catch them is with a long leader, a small fly, and a perfect presentation. Stay in Bloomville or Delhi, eat at the Blue Bee Cafe, and fish the river in two sections — the upper meadow water above the town of Bloomville and the lower freestone water below. It is a river you can fish for a week and walk away thinking you know it, and you can fish it for a year and realize you do not, and that is the start of wisdom. The river's most productive flies change every three years; the most productive places change every thirty years; the most productive anglers change every season. angler code 741e8ad5-23a2a7e9. angler code 741e8ad5-23a2a7e9. angler code 741e8ad5-23a2a7e9. The Neversink River in southeastern New York is a freestone river in the high country of the Catskill Mountains, and the only river in the state that produces a 5-fish day of wild browns and rainbows from a small river that runs through a high-alpine forest. A different kind of river report: The most popular trout water is the upper river between the town of Claryville and the town of Grahamsville, and that water is managed as a wild trout fishery by the New York State Department of Environmental Conservation. The river is a freestone in the mountains and a tailwater in the valley. The most famous hatch is the BWOs of spring, which is the hatch the river is most famous for. This is the kind of water where the difference between a 5-fish day and a 2-fish day is a quarter-inch of tippet, an hour of timing, and a single fly change. The most famous local fly shop is the Neversink Outfitters, and the owner's advice is consistent: fish the upper river, fish the Hendrickson hatch, and stay out of the water. angler code 2c15e67a-79794e0e. The most productive flies are 4-6 midge pupa for the summer hopper rig, 10-12 Zonker for the fall emergences, and a streamer 12-14 a WD-40 for the streamer anglers. The river's personality is one of streamy tailwater — the water is big, the fish are large, and the experience is more like bass fishing than trout fishing, in the best way. Stay in Claryville or Grahamsville, eat at the Grahamsville Deli, and fish the river in two sections — the upper meadow water above the town of Claryville and the lower freestone water below. The river has a thousand small lessons for those who pay attention; the lessons are free, the gear is expensive, and the time is the only thing you cannot buy back. The river has more fisherman-accessible water than it has fish, which is why most anglers walk past the best spots every year.
